The Eustachian tube (ET) is responsible for the ventilation, protection, and cleaning of the middle ear. ET dysfunction plays an important role in the pathogenesis of otitis media cases, and thus the treatment and prognosis of these cases is extremely dependent on adequate ET function, which can ultimately affect the success rate of middle ear reconstruction practices. Data research on the ET’s ventilation function is needed to ensure the success of therapy and surgery treatments in the case of Chronic Suppurative Otitis Media (CSOM) patients. This study aims to investigate ET ventilation functioning in benign type CSOM and non-otitis media subjects and to develop another modality to measure ET ventilation functioning in patients with intact and perforated tympanic membranes. A comparative cross-sectional study of 36 benign type CSOM patients and 80 non-otitis media subjects will be conducted using sonotubometry and the rated parameter measurements of ET opening frequency, amplitude and ET opening duration. Malfunctioning ventilation of the ET is more common among benign type CSOM subjects (47%) than among non-otitis media subjects (18.75%). There is a significant difference (p = 0.002) between the ET ventilation functioning of benign type CSOM subjects and non-otitis media subjects—benign type CSOM subjects have rates of malfunctioning ET ventilation that are 3.88 times higher than those of non-otitis media subjects. Patients with benign type CSOM are more likely to experience malfunctioning ET ventilation than are non-otitis media subjects.

Necrotising otitis externa in the immunocompetent patient: case series.

PubMed

Unadkat, S; Kanzara, T; Watters, G

2018-01-01

Necrotising otitis externa can be a devastating form of otitis externa. It typically tends to affect patients who are immunocompromised or diabetic. To date, there is very little in the literature about necrotising otitis externa in the immunocompetent patient population. The present paper discusses both the clinical and radiological findings in three cases of necrotising otitis externa in an immunocompetent patient cohort. The common factor among all three patients was their advanced age. Diagnosing necrotising otitis externa can be challenging because of the potentially non-specific symptoms and the absence of early radiological signs, particularly if patients are neither immunocompromised nor diabetic. Elderly patients should be considered in the same light as immunocompromised and diabetic patients in the context of necrotising otitis externa.

Evidence-based management of otitis media: a 5S model approach.

PubMed

Wasson, J D; Yung, M W

2015-02-01

The 5S model proposes five hierarchical levels (systems, summaries, synopses, syntheses and studies) of pre-appraised evidence to guide evidence-based practice. This review aimed to identify and summarise pre-appraised evidence at the highest available 5S level for the management of different subsets of otitis media: acute otitis media, otitis media with effusion, chronic suppurative otitis media and cholesteatoma in both adults and children. Data sources were pre-appraised evidence resources. Evidence freely available from sources at the highest available level of the 5S model were summarised for this review. System level evidence exists for acute otitis media and otitis media with effusion. Summary level evidence exists for recurrent acute otitis media and medical management of chronic suppurative otitis media. There is an absence of randomised controlled trials to prove the efficacy of surgical management of chronic suppurative otitis media and cholesteatoma. Until randomised controlled trial data are generated, consensus publications on the surgical management of chronic suppurative otitis media and cholesteatoma should be used to guide best practice.

Acute otitis media.

PubMed

Dickson, Gretchen

2014-03-01

One in 4 children will have at least 1 episode of acute otitis media (AOM) by age 10 years. AOM results from infection of fluid that has become trapped in the middle ear. The bacteria that most often cause AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Differentiating AOM from otitis media with effusion (OME) is a critical skill for physicians, as accurate diagnosis will guide appropriate treatment of these conditions. Although fluid is present in the middle ear in both conditions, the fluid is not infected in OME as is seen in AOM patients. Copyright © 2014 Elsevier Inc. All rights reserved.

2009-01-01

Malassezia-positive smears can be recognized from otitis externa, however, there are few references in the literature to the relation between Malassezia and otitis externa. Therefore, the bacterial and clinical characteristics of 72 cases (63 patients) with otitis externa were investigated at the Department of Otorhinolaryngology, Takinomiya General Hospital to analyze this. Thirty-seven cases were bacterial otitis externa, 20 cases were fungal otitis externa, and 15 cases were etiological agents unknown in this study. The causative organisms in fungal otitis externa were the genera Aspergillus (10 cases), Malassezia (5) and Candida (5), respectively. We suspected that 5 cases were caused by Malassezia because Malassezia cell counts were greater than 10 per field (x 400), and a large number of Malassezia were isolated from all cases. In these cases, many squamous epithelial cells were observed by direct examination, and cells from the middle or basal layer of the ear canal were also recognized in three cases. Therefore, accelerated turnover of epidermal cells of the ear canal was suggested. The main symptoms were itching and fullness in the ear, with observations of redness and erosion in objective deterioration, and we felt that these conditions were similar to seborrheic dermatitis (SD). In addition, these five cases were confirmed as fungus-related otitis externa by their improvement with antifungal agents.

Objectives. We examined relationships between otitis media risk factors, sociodemographic characteristics, and maternal knowledge and attitudes and early onset of otitis media. Methods. Pregnant women from Minnesota American Indian reservations and an urban clinic were enrolled in our study between 1998 and 2001. Follow-up was performed on enrollees’ infants until the children were 2 years old. Research nurses collected data by ear examination, from interviews and questionnaires given to enrolled mothers, and otitis media episodes that were abstracted from medical records. Results. Sixty-three percent of infants had experienced an otitis media episode by 6 months of age. Logistic regression analyses showed that maternal otitis media history, infant history of upper respiratory infection, and compliance with study visits were significantly related to early otitis media onset. Although high percentages of infants were exposed to cigarette smoke and other children and were formula fed, these factors were not related to otitis media. Mothers’ prenatal awareness of otitis media risks associated with environmental tobacco smoke exposure and formula feeding did not predict their postpartum behaviors. Conclusions. We found that infant history of upper respiratory infection and maternal otitis media history are risk factors for early otitis media in American Indian infants. Mothers’ prepartum knowledge and attitudes regarding otitis media did not predict their postpartum avoidance of risk behaviors. PMID:17194873

Objective The objective is to perform a comprehensive review of the literature up to 2015 on the genetics and precision medicine relevant to otitis media. Data Sources PubMed database of the National Library of Medicine. Review Methods Two subpanels were formed comprising experts in the genetics and precision medicine of otitis media. Each of the panels reviewed the literature in their respective fields and wrote draft reviews. The reviews were shared with all panel members, and a merged draft was created. The entire panel met at the 18th International Symposium on Recent Advances in Otitis Media in June 2015 and discussed the review and refined the content. A final draft was made, circulated, and approved by the panel members. Conclusion Many genes relevant to otitis media have been identified in the last 4 years in advancing our knowledge regarding the predisposition of the middle ear mucosa to commensals and pathogens. Advances include mutant animal models and clinical studies. Many signaling pathways are involved in the predisposition of otitis media. Implications for Practice New knowledge on the genetic background relevant to otitis media forms a basis of novel potential interventions, including potential new ways to treat otitis media.

The management of hearing loss associated with otitis media is multifaceted. Clinical practice guidelines set the collaborative prescriptive standards for the medical management of otitis media in children. Treatment of this condition does not end with the medical practitioner. There are far-reaching effects of otitis media and its sequelae that permeate every aspect of patients' lives including physiological, educational, and psychosocial. Therefore, a comprehensive interprofessional treatment plan must be designed taking into consideration best practices from a range of professions to maximize clinical outcomes, including the treating physician, speech-language pathologist, clinical audiologist, educational audiologist, and professionals in the educational setting.

The association between otitis media and vestibular symptoms has been hypothesized in the past. Thus, in this study, we aimed to critically analyze (based in a systematic review of the literature) whether patients who have otitis media are at greater risk of developing vestibular impairment or not. We performed a systematic review of the literature and identified potentially relevant articles reporting vestibular symptoms and results of vestibular function tests in patients with otitis media through searches of the PubMED, Web of Science, Scopus, and Google Scholar databases. The quality of the final set of records was assessed using the "Newcaste-Ottawa Scale". Of the 2334 records searched, 43 met our inclusion and exclusion criteria, and those included 2250 patients. The records comprised 20 longitudinal studies, 21 cross-sectional studies, and 2 case reports. Regarding the type of otitis media studied, 25 examined vestibular impairment in otitis media with effusion, 6 acute otitis media, and 12 chronic otitis media. Results of anamnesis, clinical exams, and several vestibular function tests are reported and critically discussed. Most studies evaluating the association between otitis media and vestibular symptoms have potential methodological flaws. Clinical evidence suggests that patients with otitis media have increased chances for having vestibular symptoms, delayed acquisition of developmental milestones, and abnormalities in several vestibular function tests as compared with controls. Future studies with rigorous methodology aiming to assess the clinical significance (and prognostic factors) of the association between otitis media and vestibular impairment are warranted. Key message Several studies demonstrated long-term sequelae secondary to otitis media. However, the evidence supporting those assumptions are based in low-quality evidence. Thus, better structured studies are warranted to better understand the clinical relevance of such association.

Pseudomonas otitis externa in elderly diabetics may extend aggressively to adjacent bone, cranial nerves, meninges, and vessels, leading to a clinical diagnosis of ''malignant'' external otitis. Early diagnosis is necessary for successful treatment. This study compares the findings of initial radiographs, thin-section tomography of temporal bone, CT scans of head and neck, technetium-99m methylene diphosphonate (MDP) and gallium-67 citrate scintigraphy, and single-photon emission computed tomography (SPECT) for detection of temporal bone osteomylitis in ten patients fulfilling the clinical diagnostic criteria of malignant external otitis. Skull radiographs were negative in all of the eight patients studied. Thin-section tomography was positive inmore » one of the seven patients studied using this modality. CT scanning suggested osteomyelitis in three of nine patients. Both Tc-99m and Ga-67 citrate scintigraphy were positive in 10 of 10 patients. These results suggest that technetium and gallium scintigraphy are more sensitive than radiographs and CT scans for early detection of malignant external otitis.« less

Tuberculous otitis media is a rare cause of chronic suppurative infection of the middle ear and a very uncommon form of extrapulmonary tuberculosis. Although there have been several case reports in the nonimmunosuppressive population of tuberculous otitis media, it has never been reported in an immunosuppressed allograft recipient. We present a case of diagnosed tuberculous otitis media after recurrent chronic otitis media treated several times with empiric antibiotic treatment. After the patient developed postauricular fistula and underwent surgical removal of granulation tissue, the diagnosis was made on the basis of histopathology and growth in culture of Ziehl-Neelsen. Clinical response promptly followed institution of antituberculous treatment including isoniazid, rifampicin, ethambutol, and pyrazinamide.

To evaluate the effects of otitis media with effusion on surgical parameters, patient safety, perioperative and postoperative complications. Total 890 children who underwent cochlear implantation between 2006 and 2015 were included. The ages ranged from 12 months to 63 months (mean: 32 months). The patients were divided into two groups according to the presence or absence of otitis media with effusion; otitis media with effusion group and non-otitis media group. Of 890 children, 105 had otitis media with effusion prior to surgery. In non-otitis media with group, there were 785 children. The average duration of surgery was 60min (ranged from 28 to 75min) in non-otitis media group, and 90min (ranged from 50 to 135min) in otitis media with effusion group (p<0.05). Granulation tissue and edematous middle ear and mastoid mucosa were observed in all cases of otitis media with effusion during the surgery. There was no significant difference between the complications of groups with or without otitis media with effusion (p>0.05). In 5 of 105 patients, there was a ventilation tube inserted before cochlear implantation, which did not change the outcome of implantation. There is no need for surgical treatment for otitis media with effusion before implantation since otitis media with effusion does not increase the risks associated with cochlear implantation. Operation duration is longer in the presence of otitis media with effusion. However, otitis media with effusion leads to intraoperative difficulties like longer operation duration, bleeding, visualization of the round window membrane, cleansing the middle ear granulations as well as mastoid and petrous air cells.

Tuberculosis is a global health problem that is especially prevalent in developing countries such as India. Recently, atypical presentation has become more common and a high index of suspicion is essential. This study analysed the various presenting symptoms and signs of tuberculous otitis media and the role of diagnostic tests, with the aim of formulating criteria for the diagnosis. A total of 502 patients underwent tympanomastoidectomy over a two-year period. Microbiological and histopathological examinations and polymerase chain reaction analysis of tissue taken during tympanomastoidectomy were performed. A total of 25 patients (5 per cent) were diagnosed with tuberculous otitis media. Severe mixed hearing loss, facial palsy, labyrinthine fistula, post-aural fistula, perichondritis and extradural abscess were noted. There seems to be a resurgence in tuberculous otitis media in India. Microbiological, histopathological and polymerase chain reaction tests for tuberculosis are helpful for its diagnosis.

Qualitative technetium Tc 99m bone scintigraphy using phosphate compounds and gallium 67 scintigraphy were described as a helpful means in diagnosing necrotizing external otitis (NEO). They were, however, claimed to be nonspecific. Quantitative Tc 99m methylene diphosphonate bone scintigraphy and gallium 67 scintigraphy were performed in eight patients with NEO and in 20 patients with severe external otitis, in order to prove usefulness of scintigraphy in the diagnosis of NEO. Ratios of lesion to nonlesion for bone scintigraphy were 1.67 {plus minus} 0.16 in patients with NEO and 1.08 {plus minus} 0.09 in patients with severe external otitis, and formore » gallium 67 scintigraphy they were 1.35 {plus minus} 0.24 in NEO patients and 1.05 {plus minus} 0.03 in patients with severe external otitis. There was no difference in uptake between diabetic patients with severe external otitis and nondiabetic patients. The scintigraphic studies were also evaluated using a qualitative scoring method (scores 0 to +4), according to the intensity of the radiopharmaceutical uptake. This method was found to be inferior in the diagnosis of NEO compared with the quantitative method. We conclude that lesion-to-nonlesion ratios greater than 1.5 and 1.3 on bone and gallium 67 scintigraphy, respectively, are indicative of NEO. Quantitative bone scintigraphy, which is quicker to perform, may be used as a single imaging modality for the diagnosis of NEO.« less

Acute otitis media causes discomfort to children and inconvenience to their parents. This study evaluated the quality of life in children with recurrent acute otitis media aged less than 24 months. Quality of life was evaluated in 149 children aged 10 to 24 months who were referred to the Oulu University Hospital on account of recurrent acute otitis media. The children were treated with or without surgery. Age-matched controls were selected randomly from the general child population. Parents completed the Child Health Questionnaire. The children with recurrent acute otitis media had a significantly poorer quality of life than control children. The control children with a history of a few acute otitis media episodes had a significantly poorer quality of life than those without any such history. The quality of life of the children with recurrent acute otitis media improved during the one-year follow up, regardless of the treatment, but did not reach the same level as healthy children. Acute otitis media detracted from quality of life when a generic measure was used. The mode of treatment used to prevent further recurrences of acute otitis media did not influence quality of life improvement.

Differentiating Acute Otitis Media and Acute Mastoiditis in Hospitalized Children.

Laulajainen-Hongisto, Anu; Aarnisalo, Antti A; Jero, Jussi

2016-10-01

Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

To determine the prevalence of otitis media with effusion in children younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. Retrospective study of 184 randomly included medical records from a total of 982 healthy infants evaluated for hearing screening tests. Diagnosis of otitis media with effusion was based on otoscopy (amber-gold color, fluid level, handle of malleus position), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing acute otitis media, upper respiratory tract infections on the assessment day or in the last 3 months, neuropathies and craniofacial anomalies were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between children with and without otitis media with effusion through likelihood tests and multivariate analysis. 25.3% of 184 infants had otitis media with bilateral effusion; 9.2% had unilateral. In infants with otitis media, the following were observed: chronological age of 9.6±1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. Otitis media with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to otitis media with effusion. Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. Copyright © 2015 Sociedade de Pediatria de São Paulo.

Acute otitis media (AOM) and otitis media with effusion (OME) are common infections in children, and their diagnosis and treatment have significant impacts on the health of children and the costs of providing national medical care. In 2009, the Korean Otologic Society organized a committee composed of experts in the field of otolaryngology, pediatrics, and family medicine to develop Korean clinical practice guidelines (CPG) for otitis media in children with the goal of meeting regional medical and social needs in Korea. For this purpose, the committee adapted existing guidelines. A comprehensive literature review was carried out primarily from 2004 to 2009 using medical search engines including data from Korea. A draft was written after a national questionnaire survey and several public audits, and it was editorially supervised by senior advisors before publication of the final report. These evidence-based guidelines for the management of otitis media in children provide recommendations to primary practitioners for the diagnosis and treatment of children younger than 15 yr old with uncomplicated AOM and OME. The guidelines include recommendations regarding diagnosis, treatment options, prevention and parent education, medical records, referral, and complementary/alternative medicine for treating pediatric otitis media.

Aspergillus otitis in small animals--a retrospective study of 17 cases.

Aspergillus spp. are saprophytic opportunistic fungal organisms and are a common cause of otomycosis in humans. Although there have been case reports of Aspergillus otitis externa in dogs, to the best of the authors' knowledge, this is the first retrospective case series describing Aspergillus otitis in dogs and cats. To characterize signalment, putative risk factors, treatments and outcomes of a case series of dogs and cats with Aspergillus otitis. Eight dogs and nine cats diagnosed with Aspergillus otitis. A retrospective review of medical records from 1989 to 2014 identified animals diagnosed with Aspergillus otitis based on culture. All dogs weighed greater than 23 kg. The most common putative risk factors identified in this study were concurrent diseases, therapy causing immunosuppression or a history of an otic foreign body. Aspergillus otitis was unilateral in all study dogs and most cats. Concurrent otitis media was confirmed in three dogs and one cat, and suspected in two additional cats. Aspergillus fumigatus was the most common isolate overall and was the dominant isolate in cats. Aspergillus niger and A. terreus were more commonly isolated from dogs. Animals received various topical and systemic antifungal medications; however, otic lavage under anaesthesia and/or surgical intervention increased the likelihood of resolution of the fungal infection. Aspergillus otitis is uncommon, typically seen as unilateral otitis externa in cats and larger breed dogs with possible risk factors that include immunosuppression and otic foreign bodies; previous antibiotic usage was common. © 2015 ESVD and ACVD.

Wayne State University, Hutzel Women's Hospital Neonatal Intensive Care Unit. Eighty-six preterm infants were included (gestational age <36 weeks). Otoendoscopy and tympanometry were performed to detect the presence of otitis media. Kappa statistic and logistic regression were used for statistical analysis. Otoendoscopy was performed in 85 patients. The frequency of otoendoscopy-diagnosed otitis media was 72.9% (62/85). Tympanometry could be performed on 69.76% of the ears. There was 73.5% agreement between the findings of tympanometry and those of otoendoscopy. The association between the presence of otitis media and gestational age at birth was statistically significant. The lower the gestational age, the higher the frequency of otoendoscopy-diagnosed otitis media (P = .001). Otoendoscopically diagnosed otitis media is frequent in preterm neonates. There was agreement between the results of tympanometry and those of otoendoscopy. The frequency of otitis media increased with lower gestational age. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Tuberculous otitis media and lupus vulgaris of face: an unusual association.

Tuberculous otitis media is a rare extra-pulmonary presentation of tuberculosis. Tuberculous otitis media is usually associated with pulmonary tuberculosis or tuberculosis involving nasopharynx and oropharynx. Lupus vulgaris is the most common morphological variant of cutaneous tuberculosis. The disease often affects the face and may be associated with nasal or nasopharyngeal tuberculosis. Lupus vulgaris associated with tuberculous otitis media is not reported in English literature. We report a case of 40 year old female patient who presented with symptoms of chronic suppurative otitis media and non-healing skin lesion of face. The biopsy of skin lesion showed granulomatous pathology and helped us to reach a diagnosis of tuberculous otitis media.

Tuberculous otitis media can be difficult to diagnose because it can easily be confused with other acute or chronic middle ear conditions. Compounding this problem is the fact that physicians are generally unfamiliar with the typical features of tuberculous otitis media. Finally, the final diagnosis can be difficult because it requires special culture and pathologic studies. To increase awareness of this condition, we describe two cases of tuberculous otitis media and we review the literature.

The aim of this study was to investigate the 4977 and 7400 bp deletions of mitochondrial DNA in patients with chronic suppurative otitis media and to indicate the possible association of mitochondrial DNA deletions with chronic suppurative otitis media. Thirty-six patients with chronic suppurative otitis media were randomly selected to assess the mitochondrial DNA deletions. Tympanomastoidectomy was applied for the treatment of chronic suppurative otitis media, and the curettage materials including middle ear tissues were collected. The 4977 and 7400 bp deletion regions and two control regions of mitochondrial DNA were assessed by using the four pair primers. DNA was extracted from middle ear tissues and peripheral blood samples of the patients, and then polymerase chain reactions (PCRs) were performed. PCR products were separated in 2 % agarose gel. Seventeen of 36 patients had the heterozygote 4977 bp deletion in the middle ear tissue but not in peripheral blood. There wasn't any patient who had the 7400 bp deletion in mtDNA of their middle ear tissue or peripheral blood tissue. The patients with the 4977 bp deletion had a longer duration of chronic suppurative otitis media and a higher level of hearing loss than the others (p < 0.01). Long time chronic suppurative otitis media and the reactive oxygen species can cause the mitochondrial DNA deletions and this may be a predisposing factor to sensorineural hearing loss in chronic suppurative otitis media. An antioxidant drug as a scavenger agent may be used in long-term chronic suppurative otitis media.

To investigate the clinical role of Vitamin D in prognosis of Otitis media with effusion. This prospective-controlled study was conducted at otolaryngology department in Duzce University, Turkey. The study group comprised children who were diagnosed with Otitis media with effusion between September 2016 and February 2017. Control group was conducted with children underwent circumcision or inguinal hernia repair operations that confirmed with ENT examination they do not have any sign of otitis media. After 3 months of follow-up without any treatment, unresolved cases who were accepted as chronic otitis media with effusion were operated under general anesthesia for ventilation tube application. Study and control groups were assessed depending on the serum 25(OH)Vitamin D levels at the end of 3 months; < 15 ng/mL was accepted as vitamin D deficiency. The results were compared with the control group in terms of vitamin D levels. Also, subgroup analysis was performed addressing to the complete recovery otitis media with effusion and chronic otitis media with effusion. One-hundred-seventy-four children with otitis media with effusion and 80 control patients were included to the study. One-hundred-eight (62%) out of 174 patients with otitis media with effusion was completely recovered after a 3-months follow up. Of those 66 out of 174 children, they had persistent diseases, underwent ventilation tube insertion after a 3-months follow-up. The mean 25(OH)Vitamin D level was 18.98 ± 10.60 in otitis media with effusion group and 28.07 ± 14.10 in control group and the difference was statistically significant between the study and control group (p < 0.001). Vitamin D deficiency was observed in 33 out of 66 patients (50.0%) in chronic otitis media with effusion group whilst 35 out of 108 patients (32.4%) in complete recovery otitis media with effusion group (p = 0.021). The rate of 25(OH)Vitamin D deficiency was 25% in control group which was statistically different

Otitis media is a more frequent occurrence in children, and the disease may progress from an acute to chronic state if appropriate and timely intervention is not initiated. A total of 212 children aged 6 months to 10 years were examined and treated for otitis media, in a 13-month hospital-based study. Acute otitis media was diagnosed in 130 (61.3 per cent) of the patients. There were 82 (38.7 per cent) chronic suppurative otitis media cases. The incidence of acute otitis media and chronic suppurative otitis media in the first year of life was 54.6 per cent and 45.1 per cent respectively. Chronic suppurative otitis media patients were assigned to one of three treatment groups. Recovery occurred in 70.4 per cent of amoxicillin-treated patients, in 88.9 per cent of amoxicillin-clavulanic acid treated patients and in 96.4 per cent of culture and antibiotic sensitivity test patients. Relapses were seen only in the amoxicillin (five cases) and amoxicillin-clavulanic acid (two cases) groups. The success rate in patients treated with antibiotics makes this option mandatory for an established diagnosis.

With the advent of antibiotics, complications of otitis media have become less common. It is crucial for physicians to recognise otitis media and treat its complications early. Herein, we present our institution's experience with patients who required emergency surgical intervention for complications of otitis media. Data on patients who underwent emergency surgery for complications of otitis media from 2004 to 2011 was retrieved from the archives of the Department of Otolaryngology, Changi General Hospital, Singapore. A total of 12 patients (10 male, two female) underwent emergency surgery for complications of otitis media. The median age of the patients was 25 years. Otalgia, otorrhoea, headache and fever were the main presenting symptoms. Extracranial complications were observed in 11 patients, and six patients had associated intracranial complications. The primary otologic disease was acute otitis media in six patients, chronic otitis media without cholesteatoma in three patients and chronic otitis media with cholesteatoma in three patients. Mastoidectomy and drainage of abscess through the mastoid, with insertion of grommet tube, was the main surgical approach. Two patients required craniotomy. The mean length of hospital stay was 16.2 days and the mean follow-up period was 16.3 months. Five patients had residual conductive hearing loss; two patients with facial palsy had full recovery. Otitis media can still result in serious complications in the post-antibiotic era. Patients with otitis media should be monitored, and prompt surgical intervention should be performed when necessary to attain good outcomes. Copyright: © Singapore Medical Association

It has been suggested that vitamin A deficiency may predispose to otitis media. We conducted a prospective, observational study of 200 children, ages 3 to 5 years, on the island of Saipan in the Commonwealth of the Northern Mariana Islands. Baseline measurements of serum retinol concentrations were obtained from the children, and incidence of otitis media was determined during the following year by review of medical records. The sera were also tested for concentration of other carotenoids (beta-carotene, alpha-carotene, lutein and zeaxanthin, beta-cryptoxanthin, lycopene), and alpha-tocopherol and baseline concentrations of these compounds were also examined for relationship to incidence of otitis media. Serum retinol concentrations of the children ranged from 13 to 58 microg/dl. Episodes of otitis media occurred in 22% of children during the follow-up period. Children with low serum retinol concentrations did not have an excess of episodes of otitis media (chi square for trend, 0.438; P = 0.508 for children grouped by serum retinol concentration; mean serum retinol concentrations were 29.1 and 28.6 microg/dl, respectively, for children who had and did not have a subsequent episode of otitis media). Controlling for potential confounding variables (duration of breast feeding, smoking in the household, illness or live virus vaccination in the 2 weeks before serum collection, day-care attendance) did not substantially alter this finding. Baseline serum concentrations of the other carotenoids and alpha-tocopherol also demonstrated no relation to incidence of otitis media. In the range of serum vitamin concentrations found in this population, the status of vitamin A and related compounds in children appeared to have no effect on the incidence of otitis media.

Acute otitis media (AOM) symptoms can be masked by communication deficits, common to children with autism spectrum disorders (ASD). We sought to evaluate the association between ASD and otitis media. Using ICD-9-CM diagnostic codes, we performed a retrospective case-cohort study comparing AOM, and otitis-related diagnoses among children with and without ASD. Children with ASD had a significantly increased rate of AOM, otitis media with effusion, otorrhea, and PE tube placement. Children with ASD were more than twice as likely to develop mastoiditis, and to undergo mastoidectomy and tympanoplasty. Children with ASD are more likely to have middle ear infections and otitis-related complications, highlighting the importance of routine middle ear examinations and close attention to hearing impairment in this population.

Tuberculosis is one of the most common infectious diseases of developing countries including Bangladesh. It rarely affects the middle ear. The objective is to review the literature on tuberculous otitis media and know the facts, incidence, etiology, clinical presentation, investigations and treatment of tuberculous otitis media. It is characterized by painless otorrhoea which fails to respond to the usual antimicrobial treatment, in a patient with evidence of tubercle infection elsewhere followed by multiple tympanic membrane perforations, abundant granulation tissue, and bone necrosis, preauricular lymph node enlargement. Loss of hearing is also found in patients with development of the diseases seen by the otoscopy. Combination chemotherapy is prescribed. Surgery may be required in some cases to remove sequestra and improve drainage. A high level of clinical suspicion is needed for early diagnosis and antitubercular therapy should be started as soon as possible to prevent the possible complication.

Otitis media is the most common disease of childhood, and represents an important health challenge to the 10-15% of children who experience chronic/recurrent middle ear infections. The middle ear undergoes extensive modifications during otitis media, potentially involving changes in the expression of many genes. Expression profiling offers an opportunity to discover novel genes and pathways involved in this common childhood disease. The middle ears of 320 WBxB6 F1 hybrid mice were inoculated with non-typeable Haemophilus influenzae (NTHi) or PBS (sham control). Two independent samples were generated for each time point and condition, from initiation of infection to resolution. RNA was profiled on Affymetrix mouse 430 2.0 whole-genome microarrays. Approximately 8% of the sampled transcripts defined the signature of acute NTHi-induced otitis media across time. Hierarchical clustering of signal intensities revealed several temporal gene clusters. Network and pathway enrichment analysis of these clusters identified sets of genes involved in activation of the innate immune response, negative regulation of immune response, changes in epithelial and stromal cell markers, and the recruitment/function of neutrophils and macrophages. We also identified key transcriptional regulators related to events in otitis media, which likely determine the expression of these gene clusters. A list of otitis media susceptibility genes, derived from genome-wide association and candidate gene studies, was significantly enriched during the early induction phase and the middle re-modeling phase of otitis but not in the resolution phase. Our results further indicate that positive versus negative regulation of inflammatory processes occur with highly similar kinetics during otitis media, underscoring the importance of anti-inflammatory responses in controlling pathogenesis. The results characterize the global gene response during otitis media and identify key signaling and transcription factor

Otitis media is one of the most common childhood diseases worldwide, but because of lack of doctors and health personnel in developing countries it is often misdiagnosed or not diagnosed at all. This may lead to serious, and life-threatening complications. There is, thus a need for an automated computer based image-analyzing system that could assist in making accurate otitis media diagnoses anywhere. A method for automated diagnosis of otitis media is proposed. The method uses image-processing techniques to classify otitis media. The system is trained using high quality pre-assessed images of tympanic membranes, captured by digital video-otoscopes, and classifies undiagnosed images into five otitis media categories based on predefined signs. Several verification tests analyzed the classification capability of the method. An accuracy of 80.6% was achieved for images taken with commercial video-otoscopes, while an accuracy of 78.7% was achieved for images captured on-site with a low cost custom-made video-otoscope. The high accuracy of the proposed otitis media classification system compares well with the classification accuracy of general practitioners and pediatricians (~64% to 80%) using traditional otoscopes, and therefore holds promise for the future in making automated diagnosis of otitis media in medically underserved populations.

Acute otitis media is the most common bacterial disease in children under five years; therefore, is one of the most common causes of pediatric consultation. Our objective was to determine the feasibility to consider this disease as a sentinel factor of medical attention. All the new cases of acute otitis media registered between 2008 and 2011 were collected and analyzed. Proportions, ratios, and incidence rates were determined. Also, the limits for proportions were calculated using mid P exact test. In children under five years, we observed 20 % of the cases of non-suppurative otitis media, and suppurative otitis media in 17 %. The reason for acute respiratory infection in relation to cases of otitis media in children of this age increased from 87:1 in 2008 to 53:1 in 2011. The reason of suppurative otitis media decreased in children under five years, even in 2009, when it was registered the highest number of new cases of acute respiratory infection. It was not feasible to determine if acute otitis media is a sentinel indicator; however, we could monitor medical attention indirectly.

2018-04-01

Objective: To investigate the incidence of tinnitus and its influencing factors in patients with chronic suppurative otitis media, and to provide clinical data for the study of the pathogenesis of tinnitus. Method: The clinical data of 77 patients with chronic suppurative otitis media who underwent modified radical mastoidectomy and tympanoplasty were investigated. When tinnitus and otitis media happened in the same side,then the tinnitus is judged to be otitis media related. Patients were further divided into otitis media related tinnitus and the no tinnitus groups. The differences of tinnitus severity, sleep disturbance, migraine (migraine features), snoring and gastroesophageal reflux were compared between the two groups in tinnitus occurrence and classification. Result: The incidence of otitis media related tinnitus was 55.8%(43/77). Most of the tinnitus happened(33/43) later than the occurrence of otitis media for several years or even decades. There were 43 cases of tinnitus associated with otitis media, and 31 cases without tinnitus. Between the groups, significant differences were observed in migraine features, and the P value is 0.011, while no significant differences were noticed in the severity of hearing loss and sleep disorders, snoring, gastroesophageal reflux. Ranking of otitis media related tinnitus was positively related to the degree of hearing loss, especially the bone conduction threshold. With Spearman rank correlation test,P values of mean value(250Hz,500Hz,1kHz,2kHz,4kHz), middle frequency (1kHz, 2kHz)and high frequency (4kHz) of bone conduction threshold were 0.010,0.019 and 0.003, and the correlation coefficients were 0.391,0.356 and 0.443, respectively. Conclusion: The occurrence of tinnitus in patients with otitis media may not be consistent with the time of otitis media, and theoretically later than the occurrence of otitis media is more reasonable. Whether tinnitus occurs in patients with otitis media is not related to sleep disorders

Tuberculous otitis media (TOM) is a rare cause of chronic suppurative infection of the middle ear. Due to that the symptoms and signs are often indistinguishable from those of nontuberculosis chronic otitis media and the fact that the index of suspicion is low, there is frequently a considerable delay prior to diagnosis. This can lead to irreversible complications such as facial nerve paralysis and labyrinthitis. Medical therapy with antituberculous drugs is usually effective. We report three cases with TOM diagnosticated and followed up in our Service from january 1993 to july 2001. Their charts were retrospectively reviewed for relevant historical data, physical findings, complementary studies, treatment and clinical response. We performed a review of the literature, emphasizing that TOM should be considered in the differential diagnosis of chronic otitis media.

[Why and how should serous otitis media be treated?].

PubMed

François, M; Bonfils, P; Van Haver, K; Narcy, P

1992-10-01

Serous otitis media is an extremely commonplace condition in pediatric patients and tends to resolve spontaneously. Only some forms warrant treatment. Indications for treatment include frequent superinfections, lasting hearing impairment with adverse consequences on socialization, or debilitation of the tympanic membrane carrying a risk for the ear. Tympanostomy tubes are a palliative treatment for serous otitis which restores hearing within a few hours and eliminates unfixated retractions of the tympanic membrane within a few weeks. Tympanostomy tubes may lead to complications including otorrhea and perforation of the tympanic membrane and should therefore be used only in patients with severe otitis media. Etiologic treatment of serous otitis rests on restoration of satisfactory nasal ventilation (education to improve nose-blowing, adenoidectomy), improvement of eustachian tube patency (corticosteroids), and modification of the characteristics of middle ear secretions (mucolytic agents and mucomodifying agents).

To identify genetic and environmental risk factors for otitis media in an indigenous Filipino population. Cross-sectional study. Indigenous Filipino community. Clinical history and information on breastfeeding, tobacco smoke exposure, and swimming were obtained from community members. Heads of households were interviewed for family history and personal beliefs on ear health. Height and weight were measured. Otoscopic findings were described for the presence and character of perforation or discharge. An A2ML1 duplication variant that confers otitis media susceptibility was Sanger sequenced in all DNA samples. Co-occurrence of middle ear bacteria detected by 16S rRNA gene sequencing was determined according to A2ML1 genotype and social cluster. The indigenous Filipino population has a ~50% prevalence of otitis media. Young age was associated with otitis media (4 age strata; P = .004); however, age was nonsignificant as a bistratal or continuous variable. There was no association between otitis media and sex, body mass index, breastfeeding, tobacco exposure, or deep swimming. In multivariate analyses, A2ML1 genotype is the strongest predictor of otitis media, with an odds ratio of 3.7 (95% confidence interval: 1.3-10.8; P = .005). When otitis media diagnoses were plotted across ages, otitis media was observed within the first year of life, and chronic otitis media persisted up to adulthood, particularly in A2ML1-variant carriers. Among indigenous Filipinos, A2ML1 genotype is the primary risk factor for otitis media and main determinant of disease progression, although age, the middle ear microbiome, and social clusters might modulate the effect of the A2ML1 genotype. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

[The clinical classification of acute otitis media with special reference to tympanometry].

PubMed

Subbotina, M V

We have developed a new clinical classification of acute otitis media (AOM) based on the previously proposed classifications of V.T. Palchun with co-workers (1997) and J. Jeger (1970) in which the letter near the stage of the pathological process roughly corresponds to the type of the tympanogram as follows: stage I (acute tubootitis): A, B, C; stage II (acute catarrhal otitis media): A, B, C; stage III (acute purulent otitis media, perforation stage); stage IV (acute purulent otitis media, post-perforation stage); stage V (resolution of otitis media): A - convalescence or recovery, B1 - exudate present in the tympanic cavity; B2 - persisting perforation; C - block of the auditory tube, O - the development of complications. This classification implies the necessity of tympanometry at the stage of diagnostics of AOM although it is not mandatory because the detection of exudate as a result of paracentesis at any of the stages of otitis media will allow to designate the stage of otitis either by letter A, B or C. The application of the new classification described in this article permits to more accurately than before determine the character of the pathological process in the middle ear during the course of acute otitis media which is of special importance in the clinical pediatric practice for the timely and adequate treatment of the children.

Aim To explore associations between acute otitis media in early childhood and prenatal and postnatal tobacco smoke exposure. Methods Subjects were 32,077 children born 2000 – 2005 in the Norwegian Mother and Child Study with questionnaire data on tobacco smoke exposure and acute otitis media up to 18 months of age. Multivariate regression models were used to obtain adjusted relative risks for acute otitis media. Results Acute otitis media was slightly more common in children exposed to parental smoking. The incidence from 0–6 months was 4.7% in unexposed children, and 6.0% in children exposed both pre-and postnatally. After adjusting for postnatal exposure and covariates, the relative risk for acute otitis media 0–6 months when exposed to maternal smoking in pregnancy was 1.34, 95% confidence interval: 1.06–1.69. Maternal smoking in pregnancy was associated with acute otitis media up to 12 months of age. Compared to non-exposed children, there was a slightly increased risk of recurrent acute otitis media for children exposed both pre- and postnatally with a relative risk of 1.24, 95% confidence interval: 1.01–1.52,. Conclusion Even in a cohort with relatively low exposure levels of parental smoking, maternal smoking in pregnancy was associated with an increased risk of acute otitis media in early childhood.

Stringently defined otitis-prone (sOP) children represent a new classification of the otitis-prone condition. Previous studies showed dysfunction in Ab, B-cell memory and T-cell memory responses. We sought to determine whether there are defects in numbers, phenotype and/or function of professional APC in the peripheral blood of sOP infants. APC phenotypic counts, MHC II expression and intracellular cytokine levels were determined in response to TLR7/8 (R848) stimulation by flow cytometry. Innate immune mRNA expression was measured using RT-PCR and cytokines were measured using Luminex technology. Significant (P < 0.05) increases in the phenotypic counts of monocytes and conventional dendritic cells but not plasmacytoid DCs were observed in sOP compared with non-otitis-prone (NOP) age-matched infants. No significant differences in APC activation or function were observed. Expression of various TLRs, intracellular signaling molecules and downstream cytokines was also not found to be significantly different between sOP and NOP infants. Higher numbers of APCs in sOP infants suggest the possibility of a persistent mucosal inflammatory status. Transcriptional and cytokine profiles of PBMCs among sOP infants suggest their systemic innate responses are not different compared to NOP infants. © The Author(s) 2015.

The adenoid pad has been considered a reservoir for bacteria in the pathogenesis of otitis media with effusion. This study aimed to characterize the middle ear microbiota in children with otitis media with effusion and establish whether a correlation exists between the middle ear and adenoid microbiota. Prospective, controlled study. Middle ear aspirates adenoid pad swabs were collected from 23 children undergoing ventilation tube insertion. Adenoid swabs from patients without ear disease were controls. Samples were analyzed using 16S rRNA sequencing on the Illumina MiSeq platform. Thirty-five middle ear samples were collected. The middle ear effusion microbiota was dominated by Alloiococcus otitidis (23% mean relative abundance), Haemophilus (22%), Moraxella (5%), and Streptococcus (5%). Alloiococcus shared an inverse correlation with Haemophilus (P = .049) and was found in greater relative abundance in unilateral effusion (P = .004). The microbiota of bilateral effusions from the same patient were similar (P < .001). However, the otitis media with effusion microbiota were found to be dissimilar to that of the adenoid (P = .01), whereas the adenoid microbiota of otitis media with effusion and control patients were similar (P > .05) (permutational multivariate analysis of the variance). Dissimilarities between the local microbiota of the adenoid and the middle ear question the theory that the adenoid pad is a significant reservoir to the middle ear in children with otitis media with effusion. A otitidis had the greatest cumulative relative abundance, particularly in unilateral effusions, and shares an inverse correlation with the relative abundance of Haemophilus.

Although the epidemiology of otitis media is well-known in industrialized countries, the extent of otitis media in developing Asian countries, especially in south East Asia is not well studied. To define the burden of otitis media and its sequelae in children 6-15 years of age, we enrolled elementary and junior high school children in 6 areas in rural and urban Indonesia. Randomly selected schools and classrooms were selected. All children were administered a questionnaire and had ear examinations, pneumatic otoscopy and screening audiometry. Children with any abnormality on examination or with a relevant history underwent diagnostic audiometry and tympanometry, if indicated. Of the 7005 children studied, 116 had chronic suppurative otitis media (CSOM), 30 had acute otitis media and 26 had otitis media with effusion. 2.7% of rural children had CSOM compared with 0.7% of urban children (P < 0.0001). The rates per 1000 of CSOM in rural Bali and Bandung were significantly higher (75 and 25, respectively) than in the rest of Indonesia (P < 0.05). In rural Bali, the rate per 1000 children of inactive CSOM was 63 in 6- to 9-year-old children, compared with 37 in children aged 13-15 years. Concomitantly, the rates of tympanosclerosis were 7 and 26/1000, respectively, in these age groups. In Indonesia, the prevalence of CSOM is relatively high with most disease occurring in rural areas. The high rates in rural Bali with early progression to tympanosclerosis suggest a significant burden of potentially vaccine preventable illness.

The aim of this study was to establish how reliable a given tympanogram is in predicting the presence or absence of a middle ear effusion, and to provide new views for the diagnostic information of tympanometry. The use of tympanometric gradient in addition to static admittance is the focus of this study. The authors enrolled 146 female and 129 male patients. The participants were allocated into groups as follow: Group A1 consisted of 50 healthy children. Group A2 consisted of 86 children with otitis media with effusion. Group B1 consisted of 85 healthy adults. Group B2 consisted of 54 adults with otitis media with effusion. All diagnostic otoscopic examination and tympanometry were performed in both ears. The authors analyzed the distribution of tympanograms in patients with otitis media with effusion and healthy controls. When the right and left ear canal volume of either children or adults with otitis media with effusion compared with healthy controls, no statistically significant different was observed (P > 0.05). On the other hand, the statistically significant difference was detected for the values of compliance, pressure and gradient of either children or adults with otitis media with effusion compared with healthy controls (P < 0.05). The authors found the values range from 0.01 to 1.52 mL gradients (mean least value 0.15 mL) in adults and the values range from 0.01 to 0.93 mL gradients (mean least value 0.10 mL) in children in the presence of otitis media with effusion. The authors think that tympanometric gradient may be useful to detect the otitis media with effusion.

Acute otitis media disease management.

Pichichero, M E; Casey, J R

2003-10-01

A first step in management decisions regarding otitis media must focus on accurate diagnosis to distinguish normal from acute otitis media (AOM) from otitis media with effusion (OME) or a retracted tympanic membrane without middle ear effusion. There are several classification schemes for AOM that may impact management decisions: patients with acute, persistent, recurrent, or chronic AOM may have a different distribution of bacterial pathogens and a different likelihood of success from antimicrobial therapy. Patient age, prior treatment history and daycare attendance are other important variables. The natural history of AOM without antibiotic treatment is generally favorable; however, from the few studies available, this is difficult to quantitate because the diagnosis was infrequently confirmed by tympanocentesis leaving the possibility that many patients entered into these trials may not have had bacterial AOM. Antibiotic choices should reflect pharmacokinetic/pharmacodynamic data and clinical trial results demonstrating effectiveness in eradication of the most likely pathogens based on tympanocentesis sampling and antibiotic sensitivity testing. Thereafter, compliance factors such as formulation, dosing schedule and duration of treatment and accessibility factors such as availability and cost should be taken into account. The increasing prevalence of antibiotic resistance among AOM pathogens and the changing susceptibility profiles of these bacteria should be considered in antibiotic selection. Current best practice recommends amoxicillin for uncomplicated AOM; continuing or switching to an alternative antibiotic based on clinical response after 48 hours of therapy; and selection of second line antibiotics as first line choices when the patient has already been on an antibiotic within the previous month or is otitis prone. Preferred second-line agents frequently noted in various guidelines include amoxicillin/clavulanate, cefdinir, cefpodoxime, cefprozil, and

To analyze the clinical features and treatment of tuberculous otitis media and mastoiditis. Thirteen patients with tuberculous otitis media and mastoiditis were retrospectively analyzed and the related literatures were reviewed. One case was treated by surgery only, and anti-tuberculosis treatment was given to another one patient, and surgical removal of disease lesions in combination with anti-tuberculosis treatment were given to 12 patients. One patient received surgery only was found to recur after follow-up for seven months. The patient did not recur after seven months' follow-up after antituberculosis therapy,and other patients did not recur. Although the regular anti-tuberculosis chemotherapy treatment was the main treatment for tuberculous otitis and mastoiditis, surgical treatment was helpful to achieved more rapid healing of the ear.

Diagnosis and medical treatment of otitis externa in the dog and cat.

PubMed

Jacobson, L S

2002-12-01

Otitis externa is no longer viewed as an isolated disease of the ear canal, but is a syndrome that is often a reflection of underlying dermatological disease. Causes are classified as predisposing (increase the risk of otitis); primary (directly induce otitis), secondary (contribute to otitis only in an abnormal ear or in conjunction with predisposing factors) and perpetuating (result from inflammation and pathology in ear, prevent resolution of otitis). Common primary causes include foreign bodies, hypersensitivity (particularly atopy and food allergy), keratinisation disorders (most commonly primary idiopathic seborrhoea and hypothyroidism) and earmites, particularly in cats. A systematic diagnostic procedure is required to identify causes and contributing factors. This should include history, clinical examination, otoscopy and cytology in all cases and culture and sensitivity as well as otitis media assessment and biopsy in severe and recurrent cases. Ancillary tests may be required depending on the underlying cause. Treatment consists of identifying and addressing predisposing and primary factors; cleaning the ear canal; topical therapy; systemic therapy where necessary; client education; follow-up; and preventive and maintenance therapy as required.

This study aims to describe parental experiences and perspectives of caring for a child with otitis media. We conducted a systematic review of qualitative studies on parental perspectives on caring for a child with otitis media. We searched electronic databases to July 2015. Seventeen studies involving 284 participants from six countries were included. We identified seven themes: diminishing competency (guilt over failure to identify symptoms, helpless and despairing, fear of complications, disempowered and dismissed); disrupting life schedules (disturbing sleep, interfering with work, burden on family); social isolation (stigma and judgement, sick consciousness); threatening normal development (delaying growth milestones, impairing interpersonal skills, impeding education); taking ownership (recognising symptoms, diagnostic closure, working the system, protecting against physical trauma, contingency planning); valuing support (needing respite, depending on community, clinician validation); and cherishing health (relief with treatment success, inspiring resilience). The additional medical responsibilities and anxieties of parents caring for a child with otitis media, often discounted by clinicians, can be disempowering and disruptive. Chronicity can raise doubt about treatment efficacy and parental competency, and fears regarding their child's development. Care that fosters parental confidence and addresses their concerns about the child's development may improve treatment outcomes for children with otitis media. • Otitis media is a leading cause of conductive hearing loss in children. • Parental perception of the treatment burden of otitis media can potentially affect their confidence and ability to care for their child. What is New: • We identified five themes to reflect parental perspectives: diminishing competency, disrupting life schedules, social isolation, threatening normal development, taking ownership, valuing support, and cherishing health. �

Otitis media is one of the most common office diagnoses among children in the US and the leading reason for the use of antimicrobials in pediatric practice. We undertook this study to characterize medical and surgical management of otitis media. Using claims data from a large New England health insurer, we identified all children <10 years of age who had one or more episodes of acute otitis media between July, 1995, and June, 1996, and examined patterns of treatment for this condition. Study subjects (n = 22,004) averaged 2.9 physician office visits for management of otitis media; among children <2 years of age, one-fourth had 6 or more such visits. Amoxicillin was prescribed as initial therapy in more than one-half (56.6%) of all episodes of acute otitis media, followed by cephalosporins (18.3%), trimethoprim-sulfamethoxazole (12.3%), macrolides (6.4%) and amoxicillin-clavulanate (6.0%). Over multiple episodes, however, use of amoxicillin declined by about 50%. Antimicrobial prophylaxis was received by 7.3% of all study subjects for a mean of 61.3 days; the incidence of breakthrough episodes of acute otitis media during prophylaxis varied according to the antimicrobial used (13.9, 12.3 and 19.5% for amoxicillin, trimethoprim-sulfamethoxazole and sulfisoxazole, respectively). Surgical procedures related to otitis media were performed on 3.8% of all study subjects, including 4.6% of children <2 years of age. The health care burden of otitis media is large, particularly in the first 2 years of life.

Pathogenesis and diagnosis of otitis media with ANCA-associated vasculitis.

PubMed

Yoshida, Naohiro; Iino, Yukiko

2014-12-01

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is histologically characterized by systemic necrotizing vasculitis and is clinically classified into two phases, systemic or localized. Recently, otological symptoms such as otitis media and hearing loss, not previously often associated with AAV, have been reported in AAV cases. In these cases we propose a diagnosis of otitis media with AAV (OMAAV). The ANCA titer is important for the diagnosis of OMAAV, and in most cases rapid progressive hearing loss is observed as localized AAV. Peripheral facial nerve palsy or hypertrophic pachymeningitis are coupled with 25% of cases and 18% of cases respectively. Proteinase 3-ANCA (PR3-ANCA) positive otitis media causes granulomatous formation or middle ear effusion in the middle ear, on the other hand myeloperoxidase-ANCA (MPO-ANCA) positive otitis media predominantly presents as otitis media with effusion. The early diagnosed case and the sensorineural hearing loss not progressed deaf could be recovered by the immunosuppressive therapy. Delayed diagnosis of AAV occasionally leads to progression to the irreversible phase; therefore, diagnosis at the early-localized stage is important for treating AAV. In this review, we discuss the current understanding of this newly proposed concept of OMAAV.

The role of corynebacteria in canine and feline otitis has not been investigated in detail; however, members of this genus are increasingly recognized as pathogens of otitis in both human and veterinary medicine. Here we report the first case of feline otitis associated with the recently described species Corynebacterium provencense. A seven-month old cat presented with a head tilt and ataxia was diagnosed with peripheral vestibular syndrome associated with an otitis media/interna. This took place 6 weeks after resection of a polyp, having initially shown a full recovery with topical ofloxacin and glucocorticoid treatment. Bacteriology of an ear swab yielded a pure culture of corynebacteria, which could not be identified at the species level using routine methods. However, the 16S rRNA gene sequence was 100% identical to the recently published novel corynebacterium species, Corynebacterium provencense. Whole genome sequencing of the cat isolate and calculation of average nucleotide identity (99.1%) confirmed this finding. The cat isolate was found to contain additional presumptive iron acquisition genes that are likely to encode virulence factors. Furthermore, the strain tested resistant to clindamycin, penicillin and ciprofloxacin. The cat was subsequently treated with chloramphenicol, which lead to clinical improvement. Corynebacteria from otitis cases are not routinely identified at the species level and not tested for antimicrobial susceptibility in veterinary laboratories, as they are not considered major pathogens. This may lead to underreporting of this genus or animals being treated with inappropriate antimicrobials since corynebacteria are often resistant to multiple drugs.

To review the literature involving complementary and alternative medicine (CAM) for pediatric otitis media. Multiple modalities are discussed, including prevention involving breastfeeding, nutrition, and vaccination; symptomatic treatment involving homeopathy, natural health products, and probiotics; manual manipulations involving osteopathy and chiropractics; and traditional Chinese and Japanese medicine. The information presented will assist physicians in advising patients on their decision-making during the early stages of otitis media when antibiotics and surgery are not yet indicated. A systematic literature search was conducted through January 2012 in PubMed using MESH term "otitis media" in conjunction with "complementary therapies," "homeopathy," "manipulation, osteopathic," "manipulation, chiropractic," "acupuncture therapy," "probiotics," "naturopathy," and "xylitol." Theses searches yielded 163 unique results. Abstracts and titles were evaluated for relevance. Case reports, case series, randomized controlled trials, and basic science research were included. Publications not relevant to the discussion of alternative medicine in otitis media were excluded. Bibliographies were checked for further publications. Thirty-six unique publications were reviewed. Of all therapies in complementary and alternative medicine, only xylitol has been studied in well-designed, randomized, blinded trials; it is likely effective, but compliance limits its applicability. Management of acute otitis media begins with watchful waiting. Herbal eardrops may help relieve symptoms. Homeopathic treatments may help decrease pain and lead to faster resolution. Prevention should be emphasized with elimination of risk factors, such as second hand smoke and bottle-feeding, as well as maintaining nutrition and vaccinations. Vitamin supplementation may be helpful. Probiotics and xylitol may be beneficial as well. Traditional Chinese/Japanese therapies show promising results but remain

To assess changes in the prevalence of otitis media, associated with the use of highly active antiretroviral therapy, in Brazilian human immunodeficiency virus (HIV) infected children. Division of otorhinolaryngology, Hospital das Clínicas, Sao Paulo University Medical School, Brazil. A cohort of 459 HIV-infected children aged below 13 years. The prevalence of otitis media and the serum cluster of differentiation four glycoprotein T lymphocyte count were compared for children receiving highly active antiretroviral therapy (with protease inhibitors) and those receiving standard antiretroviral therapy (without protease inhibitors). Otitis media was present in 33.1 per cent of the children. Children aged from zero years to five years 11 months receiving highly active antiretroviral therapy had a higher prevalence of acute otitis media (p=0.02) and a lower prevalence of chronic otitis media (p=0.02). Children who were receiving highly active antiretroviral therapy had a mean serum cluster of differentiation four glycoprotein T lymphocyte count greater than that of those who were receiving standard antiretroviral therapy (p<0.001). The use of highly active antiretroviral therapy in Brazilian HIV-infected children was associated with a lower prevalence of chronic otitis media.

Tuberculous otitis media (TOM) is a variable and puzzling infectious disease that is sometimes confused with other chronic middle ear diseases. A series of 7 cases (9 ears) of TOM recently treated at Osaka Prefectural Habikino Hospital is reviewed to assess the recent features of the disease. In most cases, the pathogenetic mechanism was probably aspiration of tubercle bacilli through the eustachian tube. In most cases, abundant granulations were observed in the middle and external ears, but multiple perforations of the tympanic membrane were not seen. The manifestations were variable, such as otorrhea from the perforation and otitis media with effusion. In their early stage, most cases of TOMs due to transmission via the eustachian tube are tend to resemble otitis media with effusion. Smear tests, culture, PCR, and histopathological examinations, each of which has advantages and disadvantages, must be repeated to achieve a definitive diagnosis. Tuberculin tests can be unreliable, but a chest x-ray is indispensable whenever TOM is suspected. Antitubercular chemotherapy and 2% kanamycin earwash yielded good results. Since the classical criteria for the diagnosis of TOM are no longer valid, we propose a new criterion for diagnosis in the early stage of the disease.

An aural cholesteatoma, more appropriately named tympanokeratoma, is an epidermoid cyst of the middle ear described in several species, including dogs, humans and Mongolian gerbils. The cyst lining consists of stratified, keratinizing squamous epithelium with central accumulation of a keratin debris. This case report describes vestibular ganglioneuritis and perineuritis in a dog with chronic otitis, bilateral tympanokeratomas and presumed extension of otic infection to the central nervous system. An 11-year-old intact male Dalmatian dog with chronic bilateral otitis externa and sudden development of symptoms of vestibular disease was examined. Due to the dog's old age the owner opted for euthanasia without any further examination or treatment and the dog was submitted for necropsy. Transection of the ears revealed grey soft material in the external ear canals and pearly white, dry material consistent with keratin in the tympanic bullae bilaterally. The brain and meninges were grossly unremarkable. Microscopical findings included bilateral otitis externa and media, unilateral otitis interna, ganglioneuritis and perineuritis of the spiral ganglion of the vestibulocochlear nerve and multifocal to coalescing, purulent meningitis. A keratinizing squamous epithelial layer continuous with the external acoustic meatus lined the middle ear compartments, consistent with bilateral tympanokeratomas. Focal bony erosion of the petrous portion of the temporal bone and squamous epithelium and Gram-positive bacterial cocci were evident in the left cochlea. The findings suggest that meningitis developed secondary to erosion of the temporal bone and ganglioneuritis and/or perineuritis of the vestibulocochlear nerve. Middle ear tympanokeratoma is an important and potentially life-threatening otic condition in the dog. Once a tympanokeratoma has developed expansion of the cyst can lead to erosion of bone and extension of otic infection to the inner ear, vestibulocochlear ganglion and

Otitis media (OM), as a common infectious disease, is a major cause of hearing impairment among the general population. OM remains a major public health threat in the Pacific islands, but the risks of OM have not been thoroughly explored in this region. The objective of this study is to investigate the prevalence, clinical features, and quality-of-life impacts of OM in Fiji. In the medical service trip entitled "Healing and Hope - Taiwan Cathay Heart and Hearing Medical Mission to Fiji" (TCHHMMF), we conducted a cross-sectional OM survey study in Suva and Sigatoka areas (Korolevu, Cuvu, and Lomawai) in the summer of 2015. The otitis media - 6 (OM-6) was used to survey the OM-related quality of life. In the 467 pediatric patients (aged 0-18 years old) screened, 13 (2.78%) have acute otitis media (AOM), 37 (7.92%) have otitis media with effusion (OME), and 19 (4.1%) have chronic otitis media (COM). Age (OR 0.53, 95% CI: 0.36-0.77) is a significant predictor of AOM, whereas male gender (OR 2.46, 95% CI: 1.13-5.37), smoke exposure (OR 2.81, 95% CI: 1.01-7.82), and concomitant chronic sinusitis (OR 6.05, 95% CI: 2.31-15.88) are significant predictors of OME. The mean OM-6 item scores are highest in caregiver concerns (3.8), physical suffering (3.7), and hearing loss (3.4) domains. OM is an important primary care disease in Fiji that remains under-served. It is critical to educate professionals, parents, and patients to detect and to improve care for OM. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Otitis-Prone Children Produce Functional Antibodies to Pneumolysin and Pneumococcal Polysaccharides.

The pneumococcus is a major otitis media (OM) pathogen, but data are conflicting regarding whether otitis-prone children have impaired humoral immunity to pneumococcal antigens. We and others have shown that otitis-prone and healthy children have similar antibody titers to pneumococcal proteins and polysaccharides (vaccine and nonvaccine types); however, the quality of antibodies from otitis-prone children has not been investigated. Antibody function, rather than titer, is considered to be a better correlate of protection from pneumococcal disease. Therefore, we compared the capacities of antibodies from otitis-prone (cases) and healthy (controls) children to neutralize pneumolysin, the pneumococcal toxin currently in development as a vaccine antigen, and to opsonize pneumococcal vaccine and nonvaccine serotypes. A pneumolysin neutralization assay was conducted on cholesterol-depleted complement-inactivated sera from 165 cases and 61 controls. A multiplex opsonophagocytosis assay (MOPA) was conducted on sera from 20 cases and 20 controls. Neutralizing and opsonizing titers were calculated with antigen-specific IgG titers to determine antibody potency for pneumolysin, pneumococcal conjugate vaccine (PCV) polysaccharides, and non-PCV polysaccharides. There was no significant difference in antibody potencies between cases and controls for the antigens tested. Antipneumolysin neutralizing titers increased with the number of episodes of acute OM, but antibody potency did not. Pneumolysin antibody potency was lower in children colonized with pneumococci than in noncarriers, and this was significant for the otitis-prone group ( P < 0.05). The production of functional antipneumococcal antibodies in otitis-prone children demonstrates that they respond to the current PCV and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.

ABSTRACT The pneumococcus is a major otitis media (OM) pathogen, but data are conflicting regarding whether otitis-prone children have impaired humoral immunity to pneumococcal antigens. We and others have shown that otitis-prone and healthy children have similar antibody titers to pneumococcal proteins and polysaccharides (vaccine and nonvaccine types); however, the quality of antibodies from otitis-prone children has not been investigated. Antibody function, rather than titer, is considered to be a better correlate of protection from pneumococcal disease. Therefore, we compared the capacities of antibodies from otitis-prone (cases) and healthy (controls) children to neutralize pneumolysin, the pneumococcal toxin currently in development as a vaccine antigen, and to opsonize pneumococcal vaccine and nonvaccine serotypes. A pneumolysin neutralization assay was conducted on cholesterol-depleted complement-inactivated sera from 165 cases and 61 controls. A multiplex opsonophagocytosis assay (MOPA) was conducted on sera from 20 cases and 20 controls. Neutralizing and opsonizing titers were calculated with antigen-specific IgG titers to determine antibody potency for pneumolysin, pneumococcal conjugate vaccine (PCV) polysaccharides, and non-PCV polysaccharides. There was no significant difference in antibody potencies between cases and controls for the antigens tested. Antipneumolysin neutralizing titers increased with the number of episodes of acute OM, but antibody potency did not. Pneumolysin antibody potency was lower in children colonized with pneumococci than in noncarriers, and this was significant for the otitis-prone group (P < 0.05). The production of functional antipneumococcal antibodies in otitis-prone children demonstrates that they respond to the current PCV and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.

Streptococcus pneumoniae is the predominant otitis media pathogen and its prevention through effective vaccination could diminish childhood illness and antibiotic use. This paper reviews 5 pneumococcal conjugate vaccine (PCV) trials that used otitis media as an endpoint: Northern California Kaiser Permanente (NCKP; vaccine, 7-valent PCV [PCV7]-CRM); Finnish Otitis Media (FinOM; vaccines, PCV7-CRM or PCV7-OMPC); Native American Trial (vaccine, PCV7-CRM); Pneumococcal Otitis Efficacy Trial (POET; vaccine, 11-valent PCV [PCV11]-PD). For the microbiological endpoint, vaccine efficacy against vaccine-serotype pneumococcal otitis media was about 60% across trials. Against the clinical endpoint of all episodes, vaccine efficacy was 7% (PCV7-CRM/NCKP), 6% (PCV7-CRM/FinOM), −1% (PCV7-OMPC/FinOM), and −0.4% (PCV7-CRM/Native American Trial); 34% against first episodes of ear, nose, and throat specialist-referral cases (PCV11-PD/POET). Both follow-up through 2 years of age, for the 5 trials, and long-term follow-up, for PCV7-CRM/NCKP and PCV7-CRM/FinOM, demonstrated greater vaccine efficacy against recurrent AOM and tympanostomy-tube placement, suggesting that vaccination against early episodes of AOM may prevent subsequent episodes of complicated otitis media. Although study designs varied by primary endpoint measured, age at follow-up, source of middle-ear fluid for culture, case ascertainment, and type of randomization, each clinical trial demonstrated vaccine efficacy against microbiological and/or clinical otitis media.

A 12-month study of the incidence of acute otitis media in children under three years of age in an urban practice of 10 000 patients showed that acute otitis media accounted for one in 10 of all episodes of illness presented. In contrast to findings in Scandinavia and the USA the incidence of acute otitis media in the first year of life (11.5%) was lower than in the second year (28.6%). The study included a number of children in their third year and the incidence in this group was higher still (30.8%). The problems of defining acceptable diagnostic criteria for acute otitis media, and the relation of these diagnostic criteria to the differences in our results compared with previous studies are discussed.

To determine whether there is an association between otitis media with effusion and laryngopharyngeal reflux in children. This study included 31 children with otitis media with effusion. The pepsinogen level in the middle ear fluid of all patients was measured by sandwich enzyme-linked immunosorbent assay. Each patient's middle ear fluid was investigated for Helicobacter pylori (H. pylori) using the Campylobacter-like organism (CLO) test. The middle ear pepsinogen levels were compared with those in the serum. The correlation between pepsinogen levels and H. pylori positivity in the middle ear fluid was investigated. The mean middle ear pepsinogen level (211.69 ng/mL) was significantly higher than that in the serum (24.18 ng/mL) in patients with otitis media with effusion. The middle ear aspirates of six patients (19%) were positive for H. pylori, and the correlation between H. pylori positivity and increased pepsinogen levels in the middle ear fluid was statistically significant in patients with otitis media with effusion. We detected higher pepsinogen levels and H. pylori positivity rates in the middle ear fluid than in the serum of patients with otitis media with effusion. These results support the role of laryngopharyngeal reflux in the pathogenesis of otitis media with effusion.

To examine the association between hospitalisations for otitis media and area-level measures of household crowding among children in New Zealand. Counts of hospital admissions for otitis media by census area unit were offset against population data from the 2006 national census. Area-level household crowding, exposure to tobacco smoke in the home, equivalised income and individual-level characteristics age and sex were adjusted for. To examine effect modification by ethnicity, three separate poisson models were examined for the total, Māori and non-Māori populations. Household crowding was significantly associated with hospital admissions for otitis media after adjustment in all three models. Neighbourhoods with the highest compared to the lowest proportion of crowded homes exhibited incidence rate ratios of 1.25 (95%CI 1.12-1.37) in the total population, 1.59 (95%CI 1.21-2.04) in the Māori restricted model and 1.17 (95%CI 1.06-1.32) in the non-Māori restricted model. Otitis media hospitalisations are associated with area-level measures of household crowding and other risk factors in this ecological study. The largest increase in otitis media incidence relative to neighbourhood rates of household crowding was exhibited among Māori cases of otitis media. This study adds weight to the growing body of literature linking infectious disease risk to overcrowding in the home. © 2014 The Authors. ANZJPH © 2014 Public Health Association of Australia.

To evaluate the clinical picture and microbiological findings of children hospitalized due to acute otitis media and to analyze how it differs from acute mastoiditis. A retrospective review of the medical records of all children (0-16 years) hospitalized due to acute otitis media in the Department of Otorhinolaryngology at the Helsinki University Hospital, between 2003 and 2012. Comparison with previously published data of children with acute mastoiditis (n=56) from the same institute and period of time. The most common pathogens in the children hospitalized due to acute otitis media (n=44) were Streptococcus pneumoniae (18%), Pseudomonas aeruginosa (16%), Streptococcus pyogenes (14%), and Staphylococcus aureus (14%). One of the most common pathogens of out-patient acute otitis media, Haemophilus influenzae, was absent. Otorrhea was common in infections caused by S. pyogenes and otorrhea via tympanostomy tube in infections caused by P. aeruginosa. In children under 2 years-of-age, the most common pathogens were S. pneumoniae (43%), Moraxella catarrhalis (14%), and S. aureus (7%). S. pyogenes and P. aeruginosa were only found in children over 2 years-of-age. Previous health problems, bilateral infections, and facial nerve paresis were more common in children hospitalized due to acute otitis media, compared with acute mastoiditis, but they also demonstrated lower CRP values and shorter duration of hospital stay. The number of performed tympanostomies and mastoidectomies was also comparatively smaller in the children hospitalized due to acute otitis media. S. aureus was more common and S. pneumoniae, especially its resistant strains, was less common in the children hospitalized due to acute otitis media than acute mastoiditis. Acute otitis media requiring hospitalization and acute mastoiditis compose a continuum of complicated acute otitis media that differs from common out-patient acute otitis media.

New vaccines that offer protection against otitis media caused by nontypeable Haemophilus influenzae and by Moraxella catarrhalis are under development. However, the potential health benefits and economic effects of such candidate vaccines have not been systematically assessed. We created a computerized model to compare the projected benefits and costs of (1) the currently available 7-valent pneumococcal conjugate vaccine, (2) a candidate pneumococcal-nontypeable H influenzae vaccine that has been tested in Europe, (3) a hypothetical pneumococcal-nontypeable H influenzae-Moraxella vaccine, and (4) no vaccination. The clinical probabilities of acute otitis media and of otitis media with effusion were generated from multivariate analyses of data from 2 large health maintenance organizations and from the Pittsburgh Child Development/Otitis Media Study cohort. Other probabilities, costs, and quality-of-life values were derived from published and unpublished sources. The base-case analysis assumed vaccine dose costs of $65 for the 7-valent pneumococcal conjugate vaccine, $100 for the pneumococcal-nontypeable H influenzae vaccine, and $125 for the pneumococcal-nontypeable H influenzae-Moraxella vaccine. With no vaccination, we projected that 13.7 million episodes of acute otitis media would occur annually in US children aged 0 to 4 years, at an annual cost of $3.8 billion. The 7-valent pneumococcal conjugate vaccine was projected to prevent 878,000 acute otitis media episodes, or 6.4% of those that would occur with no vaccination; the corresponding value for the pneumococcal-nontypeable H influenzae vaccine was 3.7 million (27%) and for the pneumococcal-nontypeable H influenzae-Moraxella vaccine was 4.2 million (31%). Using the base-case vaccine costs, pneumococcal-nontypeable H influenzae vaccine use would result in net savings compared with nontypeable 7-valent pneumococcal conjugate use. Conversely, pneumococcal-nontypeable H influenzae-Moraxella vaccine use would not

To evaluate the histopathologic changes of dark, transitional, and hair cells of the vestibular system in human temporal bones from patients with chronic otitis media. Comparative human temporal bone study. Otopathology laboratory. To compare the density of vestibular dark, transitional, and hair cells in temporal bones with and without chronic otitis media, we used differential interference contrast microscopy. In the chronic otitis media group (as compared with the age-matched control group), the density of type I and type II hair cells was significantly decreased in the lateral semicircular canal, saccule, and utricle (P < .05). The density of type I cells was also significantly decreased in the chronic otitis media group in the posterior semicircular canal (P = .005), but that of type II cells was not (P = .168). The mean number of dark cells was significantly decreased in the chronic otitis media group in the lateral semicircular canal (P = .014) and in the posterior semicircular canal (P = .002). We observed no statistically significant difference in the density of transitional cells between the 2 groups (P > .1). The findings of our study suggest that the decrease in the number of vestibular sensory cells and dark cells could be the cause of the clinical symptoms of imbalance of some patients with chronic otitis media. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Understanding the aetiology and resolution of chronic otitis media from animal and human studies

ABSTRACT Inflammation of the middle ear, known clinically as chronic otitis media, presents in different forms, such as chronic otitis media with effusion (COME; glue ear) and chronic suppurative otitis media (CSOM). These are highly prevalent diseases, especially in childhood, and lead to significant morbidity worldwide. However, much remains unclear about this disease, including its aetiology, initiation and perpetuation, and the relative roles of mucosal and leukocyte biology, pathogens, and Eustachian tube function. Chronic otitis media is commonly modelled in mice but most existing models only partially mimic human disease and many are syndromic. Nevertheless, these models have provided insights into potential disease mechanisms, and have implicated altered immune signalling, mucociliary function and Eustachian tube function as potential predisposing mechanisms. Clinical studies of chronic otitis media have yet to implicate a particular molecular pathway or mechanism, and current human genetic studies are underpowered. We also do not fully understand how existing interventions, such as tympanic membrane repair, work, nor how chronic otitis media spontaneously resolves. This Clinical Puzzle article describes our current knowledge of chronic otitis media and the existing research models for this condition. It also identifies unanswered questions about its pathogenesis and treatment, with the goal of advancing our understanding of this disease to aid the development of novel therapeutic interventions.

The swimmer's otitis or acute otitis externa, is a pathology that often occurs in those who practice swimming at a competitive level. The same problem often occurs in the summer with the attendance of swimming pools and bathing areas. A survey made in the United States in 2007 confirms the dynamics of the onset of this pathology, because the contamination of fungi and bacteria in the waters of the swimming pools and the sea cause the inflammation of the epithelium of the auditory canal. To face this issue, in addition to a correct diagnosis, and the necessary and appropriate therapies, it may follow the use of these medicinal preparations. The first one (A) is protective-acting, the second one (B) is characterized as a preventive, hygroscopic, moistening, antiseptic and antimycotic-acting solution. Swimmers who have been using the two (pre-and post) preparations daily for about a year have reported sporadic episodes of otitis. However, there is no doubt that these two compounds deserve a meticulous clinical trial in order to confirm their preventive and therapeutic potentials in external acute otitis.

The aim of this study was to profile and compare the middle ear microbiomes of human subjects with and without chronic otitis media. Prospective multicenter cohort study. All consecutive patients undergoing tympanoplasty surgery for chronic otitis media or ear surgery for conditions other than otitis media were recruited. Sterile swab samples were collected from the middle ear mucosa during surgery. The variable region 4 of the 16S rRNA gene in each sample were amplified using region-specific primers adapted for the Illumina MiSeq sequencer (Illumina, CA, USA)). The sequences were subjected to local blast and classified using Metagenome@KIN (World Fusion, Tokyo, Japan). In total, 155 participants were recruited from seven medical centers. Of these, 88 and 67 had chronic otitis media and normal middle ears, respectively. The most abundant bacterial phyla on the mucosal surfaces of the normal middle ears were Proteobacteria, followed by Actinobacteria, Firmicutes, and Bacteroidetes. The children and adults with normal middle ears differed significantly in terms of middle ear microbiomes. Subjects with chronic otitis media without active inflammation (dry ear) had similar middle ear microbiomes as the normal middle ears group. Subjects with chronic otitis media with active inflammation (wet ear) had a lower prevalence of Proteobacteria and a higher prevalence of Firmicutes than the normal middle ears. The human middle ear is inhabited by more diverse microbial communities than was previously thought. Alteration of the middle ear microbiome may contribute to the pathogenesis of chronic otitis media with active inflammation. 2b.

Cytological examination is crucial for the diagnosis and classification of canine otitis externa. Staining should reveal micro-organisms as perpetuating factors of otitis externa. The aim of the study was to compare four different staining methods (Diff-Quik®, Diff-Quik® after dipping in acetone, Gram Quick stain® and a commercial rapid stain for otitis externa) for ear cytology of dogs with otitis externa and to investigate the agreement of cytology and culture. In a study evaluating dogs with otitis externa, five ear swabs (one for culture and four for cytology) were taken from the horizontal part of the external auditory canal of 224 affected ears and compared semi-quantitatively. Diff-Quik® with and without prior dipping in acetone as well as the Gram Quick stain® displayed a high degree of agreement in the detection of micro-organisms (cocci p = 0.2366; rods p = 0.4832; yeasts p = 0.1574), while the commercial otitis rapid stain revealed significantly less micro-organisms (p < 0.001 for all comparisons). The results of the first three stains corresponded to the culture results by >  70%; the agreement was lower with the commercial otitis rapid stain. The quickest and easiest method was staining with Diff-Quik®. Diff-Quik® with or without prior dipping in acetone and the Gram Quick stain® had a high agreement in the detection of microorganisms and can thus be considered nearly equivalent for the diagnosis of otitis externa infectiosa. The commercial otitis rapid stain is less reliable. Based on this study Diff-Quik® can be recommended for the routine cytology of ear swabs. Additionally, a culture may be indicated and must be interpreted in the context of the cytology.

To investigate the anti-inflammatory, anti-oxidative and tissue protective effects, as well as the potential therapeutic role, of alpha-lipoic acid in experimentally induced acute otitis media. Twenty-five guinea pigs were assigned to one of five groups: a control (non-otitis) group, and otitis-induced groups treated with saline, penicillin G, alpha-lipoic acid, or alpha-lipoic acid plus penicillin G. Tissue samples were histologically analysed, and oxidative parameters in tissue samples were measured and compared between groups. The epithelial integrity was better preserved, and histological signs of inflammation and secretory metaplasia were decreased, in all groups compared to the saline treated otitis group. In the alpha-lipoic acid plus penicillin G treated otitis group, epithelial integrity was well preserved and histological findings of inflammation were significantly decreased compared to the saline, penicillin G and alpha-lipoic acid treated otitis groups. The most favourable oxidative parameters were observed in the control group, followed by the alpha-lipoic acid plus penicillin G treated otitis group. Alpha-lipoic acid, with its antioxidant, anti-inflammatory and tissue protective properties, may decrease the clinical sequelae and morbidity associated with acute otitis media.

Otitis media with effusion and obesity are both common in childhood and might share some immunological alterations. This study aimed to investigate the relationship between chronic otitis media with effusion and childhood overweight or obesity, including the potential effects of adenoid or tonsillar hypertrophy on that relationship. This study included 60 children with chronic otitis media with effusion and 86 healthy children aged from 2 to 10 years. Measures of height and weight were used to calculate the body mass index, weight for height and weight z score. The prevalence of overweight or obesity was higher in children with chronic otitis media with effusion, according to the weight for height percentiles (p = 0.012). However, neither the presence of adenoid or tonsillar hypertrophy nor the degree of adenoid hypertrophy was associated with overweight or obesity. Overweight and obesity might be risk factors for developing chronic otitis media with effusion, or vice versa.

2017-07-01

To review research addressing the polymicrobial aetiology of otitis media in Indigenous Australian children in order to identify research gaps and inform best practice in effective prevention strategies and therapeutic interventions. Literature review. Studies of aspirated middle-ear fluid represented a minor component of the literature reviewed. Most studies relied upon specimens from middle-ear discharge or the nasopharynx. Culture-based middle-ear discharge studies have found that non-typeable Haemophilus influenzae and Streptococcus pneumoniae predominate, with Moraxella catarrhalis, Staphylococcus aureus and Streptococcus pyogenes isolated in a lower proportion of samples. Alloiococcus otitidis was detected in a number of studies; however, its role in otitis media pathogenesis remains controversial. Nasopharyngeal colonisation is a risk factor for otitis media in Indigenous infants, and bacterial load of otopathogens in the nasopharynx can predict the ear state of Indigenous children. Most studies have used culture-based methods and specimens from middle-ear discharge or the nasopharynx. Findings from these studies are consistent with international literature, but reliance on culture may incorrectly characterise the microbiology of this condition. Advances in genomic technologies are now providing microbiologists with the ability to analyse the entire mixed bacterial communities ('microbiomes') of samples obtained from Indigenous children with otitis media.

In this study, we aimed to investigate the effect of CAPE and thymoquinone in experimental rat otitis media with effusion (OME) model. Intraoral approach of eustachian tube orifice cauterization were administered to 36 of 40 rats participating the study. After application of exclusion criterias, 22 rats with appropriate conditions were determined. Totally 26 rats (44 otitis model ears and 8 normal ears) were randomly divided into 5 groups. While group I was consisted of healthy rats, the other groups were consisted of rats with otitis model. Group I (saline + control group; n = 8 normal ears) and group II (saline + otitis model; n = 10 otitis model ears) received intraperitoneally saline solution. CAPE was given intraperitoneally to group III (CAPE + otitis model; n = 12 otitis model ears) at a concentration of 10 mg/kg for treatment of otitis media. Group IV (thymoquinone + otitis model; n = 12 otitis model ears) was treated orally with 10 mg/kg of thymoquinone. Group V (methylprednisolone + otitis model; n = 10 otitis model ears) was treated intraperitoneally with 1 mg/kg of methylprednisolone. Tympanic bulla samples were excised after 10th day of treatment and examined under light microscopy. Submucosal neutrophil leukocyte count of group I was significantly lower than other groups (II, IV, V) (respectively p < 0,0001, p < 0,001, p < 0,0001, Tukey test), while it was not significantly different from group III (p = 0,056, Tukey test). Submucosal neutrophil leukocyte count of group III was significantly lower than group II and group V (p = 0.029 ve p = 0.03, Tukey test). There was no significant difference between group IV and group V (p = 0,28, Tukey test). Based on these findings, it could be suggested that CAPE, anti inflammatory properties proven in the literature, plays an important role in OME treatment. Copyright © 2017 Elsevier B.V.

Acute otitis media with spontaneous tympanic membrane perforation.

PubMed

Principi, N; Marchisio, P; Rosazza, C; Sciarrabba, C S; Esposito, S

2017-01-01

The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered. Early Streptococcus pneumoniae infection due to invasive pneumococcal strains, in addition to coinfections and biofilm production due mainly to non-typeable Haemophilus influenzae, seem to be precursors of STMP. However, it is unclear why some children have several STMP episodes during the first years of life that resolve without complications in adulthood, whereas other children develop chronic suppurative otitis media. Although specific aetiological agents appear to be associated with an increased risk of AOM with STMP, further studies are needed to determine whether AOM with STMP is a distinct disease with specific aetiological, clinical and prognostic characteristics or a more severe case of AOM than the cases that occur without STMP. Finally, it is important to identify preventive methods that are useful not only in otitis-prone children with uncomplicated AOM, but also in children with recurrent AOM and those who experience several episodes with STMP.

The objective of the study was to examine the association between otitis media in childhood and dizziness in adulthood. Longitudinal, population-based cohort study of 21,962 adults (aged 20-59 years, mean 40) who completed a health questionnaire in the Nord-Trøndelag Hearing Loss Study was conducted. At 7, 10 and 13 years of age, the same individuals underwent screening audiometry in a longitudinal school hearing investigation. Children found with hearing loss underwent an ear, nose and throat specialist examination. Adults diagnosed with childhood chronic suppurative otitis media (n = 102) and childhood hearing loss after recurrent acute otitis media (n = 590) were significantly more likely to have increased risk of reported dizziness when compared to adults with normal hearing as children at the school investigation and also a negative history of recurrent otitis media (n = 21,270), p < 0.05. After adjusting for adult age, sex and socio-economic status, the odds ratios were 2.1 [95 % confidence interval (CI): 1.4-3.3] and 1.3 (95 % CI: 1.0-1.5), respectively. This longitudinal cohort study suggests that childhood chronic suppurative otitis media and childhood hearing loss after recurrent acute otitis media are associated with increased risk of dizziness in adulthood. This might reflect a permanent effect of inflammatory mediators or toxins on the vestibular system. The new finding stresses the importance of treatment and prevention of these otitis media conditions.

This is an update of a Cochrane review first published in The Cochrane Library in Issue 4, 2008 and previously updated in 2011.Acute suppurative otitis media is one of the most common infectious diseases in childhood. Recurrent acute otitis media is defined for the purposes of this review as either three or more acute infections of the middle ear cleft in a six-month period, or at least four episodes in a year. Strategies for managing the condition include the assessment and modification of risk factors where possible, repeated courses of antibiotics for each new infection, antibiotic prophylaxis and the insertion of ventilation tubes (grommets). To establish whether grommet insertion reduces the frequency of episodes of recurrent acute otitis media and the proportion of symptomatic children. The Cochrane Ear, Nose and Throat Disorders Group (CENTDG) Trials Search Co-ordinator searched the CENTDG Trials Register; Central Register of Controlled Trials (CENTRAL 2014, Issue 10); PubMed; EMBASE; CINAHL; Web of Science; Clinicaltrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 6 November 2014. Randomised controlled trials comparing grommet insertion versus control (antibiotics/other treatments/no treatment) for recurrent acute otitis media in children aged from 0 to 16 years. Two authors independently selected studies. Three authors independently assessed study quality and extracted data. We synthesised data descriptively. Two randomised controlled trials with a total of 148 participants are included in this review. The overall risk of bias in the studies is unclear.The first study randomised 95 children to grommets or control (antibiotic treatment of acute otitis media episodes). For the primary outcome, this study showed that grommet insertion leads to a mean reduction of 1.5 episodes of acute otitis media in the first six months after treatment. In six months of follow-up significantly more children in the

Tympanostomy tube placement is the most common ambulatory surgery performed on children in the United States. The goal of this study was to synthesize evidence for the effectiveness of tympanostomy tubes in children with chronic otitis media with effusion and recurrent acute otitis media. Searches were conducted in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Embase, and the Cumulative Index to Nursing and Allied Health Literature. Abstracts and full-text articles were independently screened by 2 investigators. A total of 147 articles were included. When feasible, random effects network meta-analyses were performed. Children with chronic otitis media with effusion treated with tympanostomy tubes compared with watchful waiting had a net decrease in mean hearing threshold of 9.1 dB (95% credible interval: -14.0 to -3.4) at 1 to 3 months and 0.0 (95% credible interval: -4.0 to 3.4) by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after placement of tympanostomy tubes. Associated adverse events are poorly defined and reported. Sparse evidence is available, applicable only to otherwise healthy children. Tympanostomy tubes improve hearing at 1 to 3 months compared with watchful waiting, with no evidence of benefit by 12 to 24 months. Children with recurrent acute otitis media may have fewer episodes after tympanostomy tube placement, but the evidence base is severely limited. The benefits of tympanostomy tubes must be weighed against a variety of associated adverse events. Copyright © 2017 by the American Academy of Pediatrics.

Otitis media (OM) remains a common paediatric disease, despite advances in vaccinology. Susceptibility to recurrent acute OM (rAOM) has been postulated to involve defective cell-mediated immune responses to common otopathogenic bacteria. We compared the composition of peripheral blood mononuclear cells (PBMC) from 20 children with a history of rAOM (otitis-prone) and 20 healthy non-otitis-prone controls, and assessed innate and cell-mediated immune responses to the major otopathogen nontypeable Haemophilus influenzae (NTHi). NTHi was a potent stimulator of inflammatory cytokine secretion from PBMC within 4 hours, with no difference in cytokine levels produced between PBMC from cases or controls. In the absence of antigen stimulation, otitis-prone children had more circulating Natural Killer (NK) cells (p<0.01), particularly NKdim (CD56lo) cells (p<0.01), but fewer CD4+ T cells (p<0.01) than healthy controls. NTHi challenge significantly increased the proportion of activated (CD107a+) NK cells in otitis-prone and non-otitis-prone children (p<0.01), suggesting that NK cells from otitis-prone children are functional and respond to NTHi. CD8+ T cells and NK cells from both cases and controls produced IFNγ in response to polyclonal stimulus (Staphylococcal enterotoxin B; SEB), with more IFNγ+ CD8+ T cells present in cases than controls (p<0.05) but similar proportions of IFNγ+ NK cells. Otitis-prone children had more circulating IFNγ-producing NK cells (p<0.05) and more IFNγ-producing CD4+ (p<0.01) or CD8+ T-cells (p<0.05) than healthy controls. In response to SEB, more CD107a-expressing CD8+ T cells were present in cases than controls (p<0.01). Despite differences in PBMC composition, PBMC from otitis-prone children mounted innate and T cell-mediated responses to NTHi challenge that were comparable to healthy children. These data provide evidence that otitis-prone children do not have impaired functional cell mediated immunity. PMID:29621281

The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (p<0.001). The use of HAART was associated to reduction in prevalence of chronic otitis media in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.

acute otitis media is a frequent disease in the pediatric age. About 2 % of all cases develop intracranial complications such as meningitis. The cerebral infarction originates meningitis and usually occurs in the venous system. The presence of a cerebral artery infarction secondary to acute otitis media is a rare cause described in the literature. a girl of 12 months who presented a febrile syndrome due to acute otitis media and mental confusion. On physical examination, she appeared sleepy with anisocoria, mydriasis in the right eye and left hemiparesis. The computed tomography examination showed extensive cerebral artery infarction. The patient's parents refused the proposed surgical treatment and the girl died 48 hours later. regardless of the current technological advances, the clinical prognosis of cerebral infarction associated with acute otitis media is bad. The focused neurological signs and progressive clinical deterioration should raise suspicion that antimicrobial therapy is not effective.

Determine the incidence of ear infections in cochlear implant patients, evaluate the contribution of otitis media to complications, describe the bacteriology of otitis media in the cochlear implant population, the treatment provided at our center, and the long term outcome. Data collected included age at implantation, history of otitis media or ear tubes, etiology of hearing loss, inner ear anatomy, postoperative infections, time to infection, route of antibiotic administration, and interventions for infections. Categories of infection were acute otitis media, otitis media with effusion, tube otorrhea, meningitis, scalp cellulitis, and infection at the implant site. Middle ear infections were diagnosed in 37% of implanted ears. Extension of middle ear infections into the implant site occurred in 2.8% of all implants (n = 16). Of the 16 infected devices, 10 were successfully treated with antibiotic therapy and did not require explantation. The retained implant group and explanted group both included some middle ear microbes such as Haemophilus influenzae and Streptococcus pneumoniae, as well as skin flora such as Staphylococcus aureus. Otitis media in pediatric cochlear implant patients is a common event and usually does not lead to complications of the cochlear implant. However, when the ear infection spreads to the scalp and the implant site, it is still possible to eliminate the infection using antibiotic therapy, particularly when treatment is directed to the specific organism that is recovered from the infected space and the duration and route of antibiotic treatment is carefully considered.

New Insights into Eosinophilic Otitis Media.

PubMed

Kanazawa, Hiromi; Yoshida, Naohiro; Iino, Yukiko

2015-12-01

Eosinophilic otitis media (EOM) is a type of intractable otitis media that occurs mainly in patients with bronchial asthma (BA). In 2011, the diagnostic criteria for EOM were established. EOM is characterized by the presence of a highly viscous yellowish effusion containing eosinophils and immunoglobulin E (IgE), eosinophil chemoattractants, such as eosinophil cationic protein, interleukin-5, and eotaxin. Local sensitization against foreign agents such as fungi or bacteria (e.g., Staphylococcus aureus) may result in local IgE production in the middle ear and may be responsible for the severity of EOM. The clinical features of EOM closely resemble localized eosinophilic granulomatosis polyangiitis, therefore it is necessary to be vigilant to the symptoms of mononeuritis, polyneuritis, and skin purpura during diagnosis. Standard treatment for EOM is the instillation of triamcinolone acetonide into the mesotympanum. However, severe cases exhibiting strong inflammation and otorrhea are not easily controlled with antibiotics and/or corticosteroids. We proposed the introduction of a severity score to evaluate the severity of EOM. This score correlated with local IgE levels in middle ear effusion. Clinically, the risk factors associated with this severity score were body mass index, and the duration of bronchial asthma (from the onset of BA to the age of the first consultation of otitis media to our hospital). We emphasize that early diagnosis and adequate treatment are vital in preventing progressive and sudden hearing loss resulting from EOM.

The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome plays an important role in the pathogenesis of middle ear diseases. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for cholesteatoma and chronic otitis media. NLRP3 inflammasome is a critical molecule mediating interleukin (IL)-1β responses. However, the expression of NLRP3 in the pathogenesis of cholesteatoma and chronic otitis media has not been fully examined. This study sought to assess the expression of NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in middle ear tissues in patients with cholesteatoma or chronic otitis media. Middle ear tissue samples were obtained from patients with cholesteatoma or chronic otitis media. Control middle ear samples were collected during cochlear implant surgery of patients without middle ear inflammation. The expression of NLRP3, ASC, and caspase-1 were examined by reverse transcription polymerase chain reaction (RT-PCR) assay and immunohistochemical study. The levels of mRNA of NLRP3, ASC, and caspase-1 were significantly elevated in cholesteatoma and chronic otitis media as compared with that of normal controls. The proteins of NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells in cholesteatoma and chronic otitis media.

Determine if a 2-Step multivariate analysis of historical symptom/sign data for comorbid diseases can abstract high-level constructs useful in assigning a child's "risk" for different Otitis Media expressions. Seventeen items related to the symptom/sign expression of hypothesized Otitis Media comorbidities were collected by history on 141 3-year-old children. Using established criteria, the children were assigned to 1 of 3 groups: Control (no significant past Otitis Media, n=45), Chronic Otitis Media with Effusion (n=45) and Recurrent Acute Otitis Media (n=51). Principal Component Analysis was used to identify factors representing the non-redundant shared information among related items and Discriminant Analysis operating on those factors was used to estimate the best predictor equation for pairwise group assignments. Six multivariate factors representing the assignable comorbidities of frequent colds, nasal allergy, gastroesophageal disease (specific and general), nasal congestion and asthma were identified and explained 81% of the variance in the 17 items. Discriminant Analysis showed that, for the Control-Chronic Otitis Media with Effusion comparison, a combination of 3 factors and, for the Control-Recurrent Acute Otitis Media comparison, a combination of 2 factors had assignment accuracies of 74% and 68%, respectively. For the contrast between the two disease expressions, a 2-factor combination had an assignment accuracy of 61%. These results show that this analytic methodology can abstract high-level constructs, comorbidities, from low-level data, symptom/sign scores, support a linkage between certain comorbidities and Otitis Media risk and suggest that specific comorbidity combinations contain information relevant to assigning the risk for different Otitis Media expressions.

Audiogenic seizures can be induced in genetically non-susceptible 17-day-old mice (Rb/3 strain) with various results. Priming only induces 9% of seizures, auditory insulation 3,8%, while experimental otitis leads to 79%. The hypothesis concerning disuse supersensitivity subsequent to acoustic deprivation was not confirmed by the experiment. However, modification of acoustic transmission at middle ear level induced by otitis or ear physical damage during the maturation period, exposes the upper nervous centers to intense stimulation to which the reaction is a recruiting response.

Otitis media is a group of inflammatory diseases of the middle ear. Acute otitis media and otitis media with effusion (OME) are its two main types of manifestation. Otitis media is common in children and can result in structural alterations in the middle ear which will lead to hearing losses. This work studies the effects of an OME on the sound transmission from the external auditory meatus to the inner ear. The finite element method was applied on the present biomechanical study. The numerical model used in this work was built based on the geometrical information obtained from The visible ear project. The present work explains the mechanisms by which the presence of fluid in the middle ear affects hearing by calculating the magnitude, phase and reduction of the normalized umbo velocity and also the magnitude and phase of the normalized stapes velocity. A sound pressure level of 90 dB SPL was applied at the tympanic membrane. The harmonic analysis was performed with the auditory frequency varying from 100 Hz to 10 kHz. A decrease in the response of the normalized umbo and stapes velocity as the tympanic cavity was filled with fluid was obtained. The decrease was more accentuated at the umbo.

To study the association between antibiotic intake in pregnancy and the development of otitis media and placement of ventilation tubes (VTs) in the offspring under the hypothesis that antibiotics in pregnancy may alter the offspring's propensity for disease. Data from the 700 children in the Copenhagen Prospective Studies on Asthma in Childhood 2010 unselected birth cohort study were used. Information on maternal antibiotic use and other exposures during pregnancy was collected prospectively from interviews and validated in national registries. Otitis media episodes were registered in a prospective diary for 3 years. Information regarding children's VTs was obtained from national registries. There were 514 children who had diary information and were included in the analysis regarding otitis media episodes. For VTs analysis, 699 children were included. Thirty-seven percent of the mothers received antibiotics during pregnancy, and this was associated with increased risk of otitis media (adjusted hazard ratio 1.30; 95% CI 1.04-1.63; P = .02). The risk of receiving VTs was especially associated with third trimester antibiotics (adjusted hazard ratio 1.60; 95% CI 1.08-2.36, P = .02). The risk of otitis media increased with increasing number of treatments (per-level adjusted hazard ratio 1.20; 95% CI 1.04-1.40; P = .02), but for VTs this association was not significant after adjustment. Maternal use of antibiotics during pregnancy is associated with an increased risk of otitis media and VT insertions in the offspring. Antibiotics late in pregnancy mainly contributed to these effects, pointing toward potential transmission of an unfavorable microbiome from mother to child. Copyright © 2016 Elsevier Inc.

2016-05-01

To gather and analyse information concerning the aetiology and pathology of otitis media with effusion in adults. A review of the English language literature from 1970 to the present was conducted. The available evidence suggests that otitis media with effusion in adult life is best viewed as a syndrome with a number of causes, including: infiltration of the eustachian tube by nasopharyngeal carcinoma and other local malignancies; changes in the middle ear and eustachian tube induced by radiotherapy; and systemic disease. There is now a body of evidence specifically related to the aetiology and pathology of otitis media with effusion in adult life. However, further research is required to fill in the gaps in our knowledge and understanding of this condition.

Management of chronic otitis media by subtotal petrosectomy.

Subtotal petrosectomy is the complete exenteration of all air cell tracts of the temporal bone. The isthmus of the Eustachian tube is obliterated and the external auditory canal is closed. The aim of this study was to describe the use of this technique in the management of certain cases of chronic otitis media. We conducted a retrospective revision of the patients treated in our Institution with this technique for chronic otitis media in a 5-year period (2008-2012). All charts were reviewed and data from the otomicroscopy, audiometry, radiology, surgical findings, postoperative complications and follow-up (including diffusion magnetic resonance imaging, MRI) of a minimum of 24 months were collected. In this period petrosectomy was performed on 28 patients for chronic otitis media. We treated 13 cases as primary cases, while 15 cases were secondary (patients that had already undergone another procedure in that ear). Fifteen cases had no serviceable hearing. Only 1 case had an immediate postoperative complication (infection); during the posterior follow-up, 2 cases had to be reoperated for diffusion restriction in the mastoid area revealed in the MRI 2 years after surgery. A subtotal petrosectomy is rarely performed for the treatment of chronic otitis media. However, it is a technique that we have to keep in mind for the treatment of certain cases where there is recurrence and deep hearing loss, as well as in cases with good cochlear reserve if the disease coexists with other complications.

To compare measurements of body temperature obtained with auricular thermometers versus rectal thermometers in dogs with otitis externa. Prospective study. 100 client-owned dogs: 50 with and 50 without clinical evidence of otitis externa. Dogs were evaluated for the presence of otitis externa on the basis of clinical signs, otoscopic examination, and cytologic evaluation of ear exudate. Auricular and rectal temperatures were obtained simultaneously in all dogs prior to and following ear examination. There was a high correlation between auricular and rectal temperatures in dogs with otitis externa both prior to and after ear manipulation. Significant differences were not detected in temperature measurements among dogs with different degrees of otitis externa. Auricular temperature readings obtained by use of an auricular thermometer in dogs with otitis externa are accurate measurements of body temperature, compared with rectal temperature measurements. Temperature measurements are reliable before and after examination of the ear canal.

2018-01-01

To assess the frequency of bacterial agents in chronic suppurative otitis media and the antibiotic susceptibility patterns of isolates among patients. A total of 185 patients clinically diagnosed with chronic suppurative otitis media were interviewed and middle-ear effusion samples were collected using sterile swabs. All bacterial isolates were identified by conventional microbiological methods. Antibiotic susceptibility patterns of the isolates were determined by Kirby-Bauer disc diffusion. Staphylococci spp. (64.9 per cent) were the most prevalent bacteria isolated, followed by Klebsiella spp. (12.9 per cent) and Pseudomonas aeruginosa (10.3 per cent). The most effective antibiotic for treatment of bacterial chronic suppurative otitis media was ciprofloxacin. Statistical analysis showed no significant difference in bacterial infestations among chronic suppurative otitis media patients and the antimicrobial susceptibility patterns of the bacterial isolates based on gender and age (p > 0.05). Our findings highlight the importance of a continuous and periodic evaluation of the bacteriological profile and antibiotic susceptibility patterns in chronic suppurative otitis media patients for efficacious treatment of the infection.

Biofilms in chronic suppurative otitis media and cholesteatoma: scanning electron microscopy findings.

Biofilms play a role in the pathogenesis of a variety of otorhinolaryngologic diseases, including otitis media and cholesteatoma. Despite this, relatively few studies have undertaken to demonstrate the presence of biofilms tissues from patients with chronic otitis media or infected cholesteatoma. Our objective is to detect evidence of biofilms human chronic ear infections with scanning electron microscopy (SEM). We hypothesized that bacterial biofilms are present in patients with chronic otitis media. We performed prospective collection of tissue collected during middle ear surgery from 16 patients undergoing middle ear or mastoid surgery with chronic ear infections. A total of 31 middle and mastoid tissue samples were harvested at the time of surgery and processed with critical point drying for SEM analysis. Samples were then searched for evidence of biofilms. Bacterial-shaped objects were identified that displayed both surface binding and the presence of a glycocalyx in 4 patients, findings consistent with bacterial biofilms. Most of these (3 of 4) were in patients with infected cholesteatoma, and biofims were identified in 60% of cholesteatoma cases (3 of 5). On the other hand, only 1 of 7 cases with chronic suppurative otitis media had evidence of biofilms. SEM supports the hypothesis that bacterial biofilms are common in chronic infections associated with cholesteatoma and are present in some cases of chronic suppurative otitis media without cholesteatoma.

Implantation of ossified and eroded cochlea poses many unique challenges to both the surgeon and programming team. With thorough preparation and complete knowledge about characters of specific issues, implantation would be performed successfully, and patients with ossified cochlear could benefit from cochlear implantation.

The article concerns peculiarities of surgery for chronic exudative otitis media (CEOM). The significance of miringotomy, tympanostomy, tympanotomy and tympanoantrotomy is demonstrated. The experience of the authors in surgical treatment and postoperative management of CEOM is reviewed. Of primary importance is valid selection of patients for each operation and choice of ventilatory tubes depending on the disease stage. Incidence rate and causes of recurrences in respect to the patients' age are presented and the role of follow-up in prevention of CEOM recurrences is shown. Use of temporal bone computed tomography in CEOM is specified. Key words: exudative otitis media, tympanostomy, ventilation tubes, CT of the temporal bone.

[Phospholipase and proteinase production by Malassezia pachydermatis isolated in dogs with and without otitis].

Malassezia pachydermatis is part of the skin microbiota of dogs and cats. M. pachydermatis has been associated with external otitis and seborrhoeic dermatitis, reported more often in dogs than in cats. When the physical, chemical or immunological mechanisms of the skin are altered, M. pachydermatis could act as a pathogen. Thus, several virulence factors, such as the ability to produce esterase, lipase, lipoxygenase, protease, chondroitin sulphatase, and hyaluronidase, have been studied. In the present study, we aim to identify the phospholipase activity measured at pH 6.3, and the proteinase activity measured at pH 6.3 and pH 6.8 (pH from ears of dogs with external otitis) of M. pachydermatis strains isolated from dogs with and without external otitis. The phospholipase activity was measured using a semi-quantitative method with egg yolk, and the proteinase activity with a semi-quantitative method using bovine serum albumin agar. The study was performed on 96 isolates of M. pachydermatis, 43 isolated from dogs without clinical symptoms of otitis, and 52 isolated from dogs with otitis. In our study, 75.8% of the isolates showed phospholipase activity at pH 6.3, and 81 and 97.9% of them showed proteinase activity measured at pH 6.3 and 6.8, respectively. A higher phospholipase activity was detected in strains isolated from dogs with otitis. The proteinase activity was increased at a pH of 6.8 (97.9%) in comparison to a pH of 6.3 (81%). Our results suggest that the phospholipase activity may play an important role in the invasion of host tissues in chronic canine otitis cases. The proteinase activity results obtained in this study suggest that a reduction in the pH of the treatment may improve its efficacy in the resolution of M. pachydermatis otitis.

In a double-blind, randomized trial of 553 infants and children who had otitis media with effusion ("secretory" otitis media), we compared the efficacy of a four-week course of an oral decongestant-antihistamine combination (pseudoephedrine hydrochloride, 4 mg per kilogram of body weight per day, and chlorpheniramine maleate, 0.35 mg per kilogram per day) with that of placebo. Among patients with initially unilateral disease, resolution of middle-ear effusion occurred at four weeks in 38 per cent of those treated with placebo and 34 per cent of those treated with drug (P = 0.74). Among patients with initially bilateral disease the corresponding proportions were 19 and 21 per cent, respectively (P = 0.67). Side effects were reported more often among drug-treated than placebo-treated patients. Decongestant-antihistamine combinations do not appear to be indicated for the treatment of otitis media with effusion in infants and children.

A healthy 60-year-old male was initially treated for external otitis, and subsequently received multiple surgeries including abscess drainage, temporal bone debridement, canaloplasty of the external auditory meatus, and fistula excision and was treated with numerous antibiotics at another hospital over a 1-year period. He was seen at our hospital on February 14, 2014 with a complaint of a non-healing wound behind the left ear and drainage of purulent fluid. He had no history of diabetes mellitus or compromised immune function. Computed tomography (CT) and magnetic resonance imaging (MRI) studies at our hospital showed osteomyelitis involving the left temporal, occipital, and sphenoid bones, the mandible, and an epidural abscess. Routine blood testing and tests of immune function were normal, and no evidence of other infectious processes was found. He was diagnosed with malignant otitis externa (MOE). Bone debridement and incision and drainage of the epidural abscess were performed, and vancomycin was administered because culture results revealed Corynebacterium jeikeium, Corynebacterium xerosis, and Enterococcus faecalis. MOE should be considered in healthy patients with external otitis who fail initial treatment.

In veterinary medicine, Staphylococcus schleiferi was previously assumed to be an inhabitant of carnivore skin, however, more recently, it has been repeatedly documented in the literature as both an inhabitant and as a pathogen. In order to determine the frequency of nasal carriage, and the methicillin susceptibility pattern of S. schleiferi from healthy dogs as well as dogs with otitis and/or pyoderma, a prospective study including 24 dogs with healthy ears and skin, 27 dogs with healthy ears and pyoderma, 15 dogs with otitis without pyoderma and 20 dogs with both otitis and pyoderma was performed. Specimens were obtained and cultured and isolates were identified as S. schleiferi based on growth and biochemical characteristics. S. schleiferi was isolated from the nares of 1 healthy dog, 3 dogs with recurrent pyoderma, 2 dogs with recurrent otitis, and 1 dog with both recurrent otitis and pyoderma. One of the S. schleiferi isolates was methicillin resistant. Nasal carriage of S. schleiferi does occur in healthy dogs as well as dogs with otitis and pyoderma. Methicillin resistant and sensitive S. schleiferi can be found in the nares of dogs with diseased ears and skin. Copyright © 2012 Elsevier B.V. All rights reserved.

Upper respiratory tract infection is a nonspecific term used to describe an acute infection involving the nose, paranasal sinuses, pharynx and larynx. Upper respiratory tract infections in children are often associated with Eustachian tube dysfunction and complicated by otitis media, an inflammatory process within the middle ear. Environmental, epidemiologic and familial risk factors for otitis media (such as sex, socioeconomic and educational factors, smoke exposure, allergy or duration of breastfeeding) have been previously reported, but actually no data about their diffusion among Sicilian children with upper respiratory tract infections are available. To investigate the main risk factors for otitis media and their prevalence in Sicilian children with and without upper respiratory tract infections. A case-control study of 204 children with upper respiratory tract infections who developed otitis media during a 3 weeks monitoring period and 204 age and sex-matched healthy controls. Seventeen epidemiologically relevant features were inventoried by means of standardized questionnaires and skin tests were performed. Univariate analysis and multivariate logistic regression analysis were used to examine the association between risk factors and occurrence of otitis media. Otitis media resulted strongly associated to large families, low parental educational attainment, schooling within the third years of life (p<0.05); children were more susceptible to develop otitis media in the presence of asthma, cough, laryngopharyngeal reflux disease, snoring and apnea (p<0.05). Allergy and urban localization increased the risk of otitis media in children exposed to smoke respectively of 166% and 277% (p<0.05); the joint effect of asthma and presence of pets in allergic population increased the risk of recurrence of 11%, while allergy, cough and runny nose together increased this risk of 74%. Upper respiratory tract infections and otitis media are common childhood diseases strongly

Aviation Fuel Exposure Resulting in Otitis Externa with Vertigo.

PubMed

Long, Robert J; Charles, Reese A

2018-07-01

Otitis externa secondary to irritant or chemical exposure is well documented; however, specifically secondary to jet fuel exposure and its associated toxicology is not. Over 2 million military and civilian personnel per year are occupationally exposed to aviation fuels. An aircraft maintainer presented with noninfectious acute otitis externa secondary to external ear canal exposure to JP-5 jet fuel. Proper exposure guidelines were followed, but it was not realized that the external ear canal was involved. The first symptoms to emerge were vertigo, dizziness, and disequilibrium; however, on physical exam it appeared that there was no middle ear involvement. Otitis externa normally does not present with vestibular symptoms as the pathology affects the external ear canal dermal tissue. Upon review of JP-5's toxicology profile, dermal absorption is a route of entry and can cause general neurological symptoms, including loss of coordination. This case highlights potential deficiencies in the standardized safety data sheets that are used after exposure. Without mention of possible auricular exposure one may focus on the logical protection of the eyes, mouth, and visible skin. This is concerning due to potential delayed exposure symptoms, dermal absorption, high level of dermal destruction, and the close proximity to the sensory system. The goal of this case report is to improve the knowledge of providers caring for personnel who may be exposed and to suggest possible revisions to the Safety Data Sheets for jet fuel.Long RJ, Charles RA.

2016-12-01

Despite evidence that therapeutic mastoidectomy does not improve outcomes in noncholesteatomatous chronic otitis media, it remains widely performed. An up-to-date systematic review is undertaken and conclusions drawn regarding the best evidence-based practice of its management. PubMed, Google Scholar, Medline Embase, Cochrane, and Web of Science. A combination of the following words was used: chronic otitis media, chronic suppurative otitis media, COM, CSOM, mastoidectomy, tympanoplasty, atelectasis, retraction, tympanic perforation, and therapeutic. From 1742 studies, 7 were selected for full analysis with respect to the benefit of mastoidectomy in the management of active and inactive mucosal chronic otitis media. Most were retrospective studies, with 1 prospective randomized controlled trial available. Overall, there was no evidence to support routine mastoidectomy in conjunction with tympanoplasty in chronic otitis media. For ears with sclerotic mastoids, the evidence suggested that there may be some benefit as a staged procedure. Two studies were analyzed for the benefit of mastoidectomy in addition to tympanoplasty for the management of the atelectatic ear (inactive squamous chronic otitis media). The conclusion was also that mastoidectomy added no benefit. Examination of the available literature supports the notion that therapeutic mastoidectomy does not lend any additional benefit to the management of noncholesteatomatous chronic otitis media. This has implications for patient care, both clinically and financially. Further research, ideally in the form of a prospective, multi-institutional, geographically wide, ethnically diverse, randomized controlled trial, is needed to further support this notion. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

This case-control study investigated the possible association between home environmental air pollutants and their effect on otitis media and asthma in children. Patients with physician-diagnosed otitis (n = 125, 74% response), with asthma (n = 137, 80% response), and controls (n = 237, 72% response) from a private pediatric practice seen between October 1986 and May 1987 were studied. A questionnaire inquired about housing characteristics (i.e., age, insulation, heating system) and sources of indoor air pollution such as cigarette smoking, use of woodburning stoves, household pets, etc. Analysis of the responses confirmed previous findings of significant relationships between maternal smokingmore » (P = .021), and the presence of pets (P = .034) and the occurrence of asthma. A newly reported relationship between exposure to woodburning stoves and the occurrence of otitis (P less than .05) was reported. This implicates yet another risk factor (wood burning) in the etiology of otitis media.« less

This study evaluated the relationship between radiation and Eustachian tube dysfunction, and examined the radiation dose required to induce otitis media with effusion. The function of 36 Eustachian tubes in 18 patients with head and neck cancer were examined sonotubometrically before, during, and 1, 2 and 3 months after, intensity-modulated radiotherapy. Patients with an increase of 5 dB or less in sound pressure level (dB) during swallowing were categorised as being in the dysfunction group. Additionally, radiation dose distributions were assessed in all Eustachian tubes using three dose-volume histogram parameters. Twenty-two of 25 normally functioning Eustachian tubes before radiotherapy (88.0 per cent) shifted to the dysfunction group after therapy. All ears that developed otitis media with effusion belonged to the dysfunction group. The radiation dose threshold evaluation revealed that ears with otitis media with effusion received significantly higher doses to the Eustachian tubes. The results indicate a relationship between radiation dose and Eustachian tube dysfunction and otitis media with effusion.

Otitis media is the most common infection second only to viral upper respiratory infection in the outpatient setting. Tympanostomy tube insertion (TTI) is the most common ambulatory surgical procedure in the United States. While many risk factors for otitis media have been identified, atopic conditions have been under-recognized as risk factors for recurrent and persistent otitis media. Given that asthma and other atopic conditions are the most common chronic conditions during childhood, it is worth examining the association between atopic conditions and risk of otitis media, which can provide insight into how atopic conditions influence the risk of microbial infections. This paper focuses its discussion on otitis media, however it is important that the association between atopic conditions and risk of otitis media be interpreted in the context of the association of atopic conditions with increased risks of various microbial infections.

A low level of serum antibody to antigens expressed by Streptococcus pneumoniae has been proposed to explain the susceptibility of children to recurrent episodes of acute otitis media (hereafter, “otitis-prone children”). By use of enzyme-linked immunospot assays, the percentages of memory B cells to pneumococcal protein antigens PhtD, LytB, PcpA, PhtE, and Ply were compared between otitis-prone and non–otitis-prone children at the time of acute otitis media or nasopharyngeal colonization with S. pneumoniae. We found significantly lower percentages of memory B cells to 3 pneumococcal protein antigens (PhtD, PhtE, and Ply) and reduced antigen-specific immunoglobulin G concentrations in otitis-prone children, compared with non–otitis-prone children.

Otitis externa, a benign inflammatory process of the external auditory canal, is general responsive to local therapy. Some patients however, develop a less controllable disease leading to chondritis and osteomyelitis of the base of the skull. The direct invasive characteristic of the disease has led to the descriptive term malignant external otitis (MEO), more appropriately called necrotizing or invasive external otitis. Malignant external otitis is caused by an aggressive pseudomonas or proteus infection that almost exclusively occurs in elderly diabetic patients. The primary imaging modalities previously used in the diagnosis and evaluation of MEO were standard planar scintigraphic techniques withmore » technetium-99M (/sup 99m/Tc) bone agents and gallium-67 (/sup 67/Ga), and pluridirectional tomography. The advent of high resolution computed tomography (CT) effectively allowed demonstration of the soft tissue extension and bone destruction associated with MEO, but still suffered from the low sensitivity constraints of all radiographic techniques in determining early inflammatory bone involvement. Recent work suggests that scintigraphic detection of MEO with /sup 99m/Tc-MDP and /sup 67/Ga, combined with the cross-sectional resolution of single photon emission computed tomography (SPECT) may be of value in planning treatment of this inflammatory condition.« less

Otitis media is the primary cause of antibiotic prescription in children. Two-thirds of all children experience at least one episode of otitis media before the age of 7 years. The aim of this study was to characterise the attributable effect of several modifiable risk exposures on the risk of >3 episodes of otitis media at age 18 months and 7 years within a large prospective national birth cohort. The study used the Danish National Birth Cohort comprising information about otitis media and risk exposures from more than 50,000 mother-child pairs from the period 1996-2002. Logistic regression models were used to estimate odds ratios for the risk factors and to calculate the population attributable fraction. Short time with breastfeeding, early introduction to daycare, cesarean section, and low compliance to the national vaccination program were all associated with an increased risk of >3 episodes of otitis media at 18 months of age and at 7 years of age. The fraction of children with otitis media attributed from breastfeeding lasting for less than 6 months was 10%. Introduction to daycare before the age of 12 months attributed with 20% of the cases of >3 episodes of otitis media. Short duration of breastfeeding, early introduction into daycare, cesarean section, and low compliance with the national vaccination program increased the risk of experiencing >3 episodes of otitis media at 18 months, and at 7 years of age. These are factors that all can be modulated. Copyright © 2018 Elsevier B.V. All rights reserved.

Otitis media is one of the most common diseases in small children. This underlines the importance of optimizing diagnostics and treatment of the condition. Recent literature points toward a stricter approach to diagnosing acute otitis media (AOM). Moreover, ventilating tube treatment for recurrent AOM (RAOM) and chronic otitis media with effusion (COME) has become the most frequently performed surgical procedure in pre-school children. Therefore, the Danish Health and Medicines Authority and the Danish Society of Otorhinolaryngology, Head and Neck Surgery deemed it necessary to update the Danish guidelines regarding the diagnostic criteria for acute otitis media and surgical treatment of RAOM and COME. The GRADE system (The Grading of Recommendations Assessment, Development and Evaluation) was used in order to comply with current standards of evidence assessment in formulation of recommendations. An extensive literature search was conducted between July and December 2014. The quality of the existing literature was assessed using AGREE II (Appraisal of Guidelines for Research & Evaluation), AMSTAR (assessing the Methodological Quality of Systematic Reviews), QUADAS-2 (Quality of Diagnostic Accuracy Studies), Cochrane Risk of Bias Tool for randomized trials and ACROBAT-NRSI (A Cochrane Risk of Bias Assessment Tool for Non-Randomized Studies). The working group consisted of otolaryngologists, general practitioners, pediatricians, microbiologists and epidemiologists. Recommendations for AOM diagnosis, surgical management for RAOM and COME, including the role of adenoidectomy and treatment of ventilating tube otorrhea, are proposed in the guideline.

Bowd, Alan D

2005-02-01

Otitis media is endemic among Inuit, First Nations and Métis children in northern Canada, with prevalence rates in some communities as high as 40 times that found in the urban south. Hearing impairment, much of it attributable to chronic otitis media, is the most common health problem in parts of the arctic, and conductive hearing loss among children may affect as many as two-thirds. There is a need for systematic data based on consistent disease definitions and measures, and taking account of cross-cultural methodological issues and sampling. Otitis media is most likely to develop in infancy. Susceptibility has been linked to immune defects and to a variety of environmental factors. Among the most significant are diet, the decline in initiation and maintenance of breastfeeding, and exposure to cigarette smoke. Hearing loss has been related to difficulties in language acquisition, and to subsequent issues with literacy and school achievement, including learning disabilities and attention deficits. The economic and social costs of otitis media are substantial. Approaches to treatment and prevention have enjoyed limited success. Public health and medical practice need to be informed by the traditional knowledge and practices of indigenous peoples.

Otitis media (OM) is considered a potentially severe disease due to the risk of complications. To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

The aim of our case study is to illustrate diagnostic and therapeutic difficulties as well as gravity related to tuberculous otitis media with intracranial complications. A diabetic male patient of 65 years old was treated for subacute otitis media with mixed hearing loss. Early bacteriologic samples from ear exudates revealed opportunistic pathogens. Clinical evolution after four months was marked by the appearance of mastoiditis with facial paralysis. The patient presented petrositis and bilateral laryngeal paralysis with lymphocytic meningitis after six and eight months respectively. Tuberculosis was suspected after a positive ELlspot tests with appearance of biologic markers of hepatic dysfunction like cholestasis and hepatic cytolysis. Although antituberculous treatment was instaured even without isolation of acid fast bacilli, the patient died after ten months. Subacute otitis media complicated by labyrinthitis, early onset of facial paralysis or any other oranial nerve palsy should raise suspicion of tuberculosis. The prognosis depends on early diagnosis which remains difficult despite morphological and metabolic imaging. The diagnostic workup should include histological and bacteriologic samples, liver markers of intacellular damage as well as ELlspot test. The prognosis remains poor especially in immunocompromised patients despite appropriate treatment.

Acute otitis media is one of the most common infectious diseases worldwide in spite of the widespread vaccination. The present study was conducted to explore the effects of fisetin on mouse acute otitis media models. The animal models were established by lipopolysaccharide (LPS) injection into the middle ear of mice via the tympanic membrane. Fisetin was administered to mice for ten days through intragastric administration immediate after LPS application. Hematoxylin and eosin (H&E) staining was performed and the pro-inflammatory cytokines, including interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), IL-6 and VEGF, were measured through enzyme-linked immunosorbent assay (ELISA) method and RT-qPCR analysis. Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway was detected by immunoblotting assays. Reactive oxygen species (ROS) generated levels were determined through assessment of anti-oxidants, and TXNIP/MAPKs signaling pathways were explored to reveal the possible molecular mechanism for acute otitis media progression and the function of fisetin. Fisetin reduced mucosal thickness caused by LPS. In fisetin-treated animals, pro-inflammatory cytokine release was downregulated accompanied with TLR4/NF-κB inactivation. ROS production was significantly decreased in comparison to the LPS-treated group. The TXNIP/MAPKs signaling pathway was inactivated for fisetin treatment in LPS-induced mice with acute otitis media. The above results indicated that fisetin improved acute otitis media through inflammation and ROS suppression via inactivating TLR4/NF-κB and TXNIP/MAPKs signaling pathways.

Caregivers of 160 children, age range 4-7 years, suffering from either upper respiratory tract infections (URTI) and/or otitis media with effusion (OME), completed the generic Strengths and Difficulties Questionnaire (SDQ) and impact supplement before consulting the ENT physician. In the ENT sample significant differences were found for the SDQ subscales hyperactivity-inattention and emotional symptoms, as well as for the total difficulties score and impact rating, compared to the U.S. community sample (p<.0005). Classification of severity (low, medium, high difficulties) for SDQ symptom scores, according to U.S. normative scoring bands, showed significantly more children in higher severity bands for SDQ total difficulties (p<.0005), emotional symptoms (p<.005), hyperactivity-inattention (p<.001) and prosocial behaviour (p<.005). This is expressed in a larger percentage of scores in the high difficulties (>90% of scores) than in the medium difficulties (80-90% of scores) band for most ENT SDQ scores, except for SDQ prosocial behaviour (18.1%) and total difficulties (17.5%). The level of psychosocial adaptation seems to be compromised in the Dutch ENT sample for both internalising (emotional symptoms) and externalising (hyperactivity-inattention) behaviour dimensions, which indirectly supports the cumulative effects of a disease history with chronic otitis media, resulting in poorer attention skills and fewer social interactions present. The classification of SDQ symptom severity, indicates that any behavioural effect of otitis media and resulting hearing loss is within the borderline score range, asking for vigilance regarding possible

Our study aimed to evaluate pathologic changes in the cochlear (inner and outer hair cells and stria vascularis) and vestibular (vestibular hair cells, dark, and transitional cells) sensorial elements in temporal bones from donors who had otitis media. We studied 40 temporal bones from such donors, which were categorized in serous otitis media (SOM), serous-purulent otitis media (SPOM), mucoid/mucoid-purulent otitis media (MOM/MPOM), and chronic otitis media (COM); control group comprised 10 nondiseased temporal bones. We found significant loss of inner and outer cochlear hair cells in the basal turn of the SPOM, MOM/MPOM and COM groups; significant loss of vestibular hair cells was observed in the MOM/MPOM and COM groups. All otitis media groups had smaller mean area of the stria vascularis in the basal turn of the cochlea when compared to controls. In conclusion, our study demonstrated more severe pathologic changes in the later stages of the continuum of otitis media (MOM/MPOM and COM). Those changes seem to progress from the basal turn of the cochlea (stria vascularis, then inner and outer hair cells) to the middle turn of the cochlea and to the saccule and utricle in the MOM/MPOM and COM stages.

Theories of otitis media pathogenesis, with a focus on Indigenous children.

PubMed

Wiertsema, Selma P; Leach, Amanda J

2009-11-02

Otitis media is a common childhood illness associated with hearing loss, social disadvantage and medical costs. Prevalence and severity are high among Indigenous children. Respiratory bacterial and viral pathogens ascend the eustachian tube from the nasopharynx to the middle ear, causing inflammation, fluid accumulation, and bulging of the tympanic membrane, with or without pain. Among Australian Indigenous children, ear disease commences earlier in life, and involves multiple strains of bacterial pathogens at high density that persist longer. Persistent nasal discharge, overcrowded living conditions (particularly exposure to many children) and poor facilities for washing children perpetuate a vicious cycle of transmission and infection. Risk factors include environmental tobacco smoke, season, lack of breastfeeding, younger age and immature immune system, and possibly genetic factors. The innate immune system is a critical first response to infection, particularly as passive maternal antibodies decline and during the maturation of the infant adaptive immune response. The relative contributions of innate factors to protection from otitis media are currently not well understood. A diversity of antibodies that target strain-specific and conserved antigens are generated in response to natural exposure to otitis media pathogens (or to vaccines). Deficiencies in these antibodies may explain susceptibility to recurrent infections. Incremental contributions from all these elements are likely to be important in otitis media susceptibility versus protection. Effective medical and social strategies to prevent early age of onset are urgently needed.

Bacterial resistance in acute otitis can result in bacterial persistence and biofilm formation, triggering chronic and recurrent infections. To investigate the middle ear inflammatory response to bacterial infection in human and chinchilla temporal bones. Six chinchillas underwent intrabullar inoculations with 0.5 mL of 106 colony-forming units (CFUs) of Streptococcus pneumoniae, serotype 2. Two days later, we counted bacteria in middle ear effusions postmortem. One ear from each chinchilla was processed in paraffin and sectioned at 5 µm. The opposite ear was embedded in epoxy resin, sectioned at a thickness of 1 µm, and stained with toluidine blue. In addition, we examined human temporal bones from 2 deceased donors with clinical histories of otitis media (1 with acute onset otitis media, 1 with recurrent infection). Temporal bones had been previously removed at autopsy, processed, embedded in celloidin, and cut at a thickness of 20 µm. Sections of temporal bones from both chinchillas and humans were stained with hematoxylin-eosin and immunolabeled with antifibrin and antihistone H4 antibodies. Histopatological and imminohistochemical changes owing to otitis media. Bacterial counts in chinchilla middle ear effusions 2 days after inoculation were approximately 2 logs above initial inoculum counts. Both human and chinchilla middle ear effusions contained bacteria embedded in a fibrous matrix. Some fibers in the matrix showed positive staining with antifibrin antibody, others with antihistone H4 antibody. In acute and recurrent otitis media, fibrin and neutrophil extracellular traps (NETs) are part of the host inflammatory response to bacterial infection. In the early stages of otitis media the host defense system uses fibrin to entrap bacteria, and NETs function to eliminate bacteria. In chronic otitis media, fibrin and NETs appear to persist.

Tuberculous otitis media (TOM) is an uncommon, insidious, and frequently misdiagnosed form of tuberculosis (TB). In particular, TOM is usually secondary to direct transmission from adjacent organs, while the primary form has been rarely reported. The main aim of treatment is to start the patient on an antitubercular regime and early surgical intervention to decompress the facial nerve if involved. The case report of a twenty year-old male with bilateral tuberculous otitis media, who presented himself with fever followed by sequential bilateral facial nerve paralysis, bilateral profound hearing loss, and abdominal tuberculosis leading to intestinal perforation, is presented. To the best available knowledge and after researching literature, no such case depicting the extensive otological complications of tuberculosis has been reported till date. Tuberculosis of the ear is a rare entity and in most cases the clinical features resemble that of chronic otitis media. The diagnosis is often delayed due to varied clinical presentations and this can lead to irreversible complications. Early diagnosis is essential for prompt administration of antitubercular therapy and to prevent complications.

The objective of the present study was to elucidate the specific features of the clinical course of acute otitis media as well as the peculiarities of the vestibular function and the microbial paysage associated with this pathological condition under the present-day conditions. The study included 135 patients presenting with acute otitis media (AOM) at different stages of the disease. The discharge obtained from the tympanic cavity of all the patients was examined with the use of polymerase chain reaction in real time, audiological and vestibulogical methods. The distinctive features of acute otitis medium associated with Streptococcus pneumoniae infection were found to be the intense pain syndrome with the symptoms of intoxication, well apparent inflammatory changes in the tympanic membrane as revealed by otoscopy, the increased frequency of sensorineural impairment of hearing, and the characteristic type B tympanometric curve. Typical of AOM associated with Haemophilus influenza infection are the mild pain syndrome, weak changes in the tympanic membrane as revealed by otoscopy, conductive hearing loss, and the type C tympanometric curve.

Primary tuberculous otitis media of which infection focus cannot be found elsewhere in the body is a rare disease. Route of the infection has been hypothesized as Eustachian tube or external auditory canal with tympanic membrane perforation but it is hard to ascertain in the patient. We present a case of an 8-year-old child who suffered chronic otorrhea after tympanostomy tube insertion. The radiological and histopathological findings revealed tuberculous otitis media, which occurred as a complication of tympanostomy tube insertion.

To evaluate the effects of oral steroids alone or followed by intranasal steroids versus watchful waiting on the resolution of otitis media with effusion in children aged 2-11 years. A total of 290 children with bilateral otitis media with effusion were assigned to 3 groups: group A was treated with oral steroids followed by intranasal steroids, group B was treated with oral steroids alone and group C was managed with watchful waiting. Patients were evaluated with audiometry and tympanometry. The complete resolution rates of otitis media with effusion were higher in groups A and B than in group C at six weeks. There were no significant differences in otitis media with effusion resolution rates between the groups at three, six and nine months. Oral steroids lead only to a quick resolution of otitis media with effusion, with no long-term benefits. There was no benefit of using intranasal steroids in the management of otitis media with effusion.

Indications and radiological findings of acute otitis media and its complications.

PubMed

Pont, Elena; Mazón, Miguel

Most cases of acute otitis media resolve with antibiotics and imaging is not required. When treatment fails or a complication is suspected, imaging plays a crucial role. Since the introduction of antibiotic treatment, the complication rate has decreased dramatically. Nevertheless, given the critical clinical relevance of complications, the importance of early diagnosis is vital. Our objective was to review the clinical and radiological features of acute otitis media and its complications. They were classified based on their location, as intratemporal or intracranial. Imaging makes it possible to diagnose the complications of acute otitis media and to institute appropriate treatment. Computed tomography is the initial technique of choice and, in most cases, the ultimate. Magnetic resonance is useful for evaluating the inner ear and when accurate evaluation of disease extent or better characterization of intracranial complications is required.

Tensor veli palatini electromyography for monitoring Eustachian tube rehabilitation in otitis media.

PubMed

Picciotti, P M; Della Marca, G; D'Alatri, L; Lucidi, D; Rigante, M; Scarano, E

2017-05-01

The pathogenesis of otitis media is related to Eustachian tube dysfunction. The tensor veli palatini muscle actively opens the Eustachian tube and promotes middle-ear ventilation. This study describes a technique for paratubal electromyography that uses a surface, non-invasive electrode able to record tensor veli palatini muscle activity during swallowing. Twenty otitis media patients and 10 healthy patients underwent tensor veli palatini electromyography. Activity of this muscle before and after Eustachian tube rehabilitation was also assessed. In 78.5 per cent of patients, the electromyography duration phase and/or amplitude were reduced in the affected side. The muscle action potential was impaired in all patients who underwent Eustachian tube rehabilitation. This study confirmed that Eustachian tube muscle dysfunction has a role in otitis media pathogenesis and showed that muscle activity increases after Eustachian tube rehabilitation therapy.

Necrotising otitis externa is associated with high morbidity and mortality rates. This study investigated whether temporomandibular joint involvement had any prognostic effect on the course of necrotising otitis externa in patients who had undergone hyperbaric oxygen therapy after failed medical and sometimes surgical therapy. A retrospective case series was conducted of patients in whom antibiotic treatment and surgery had failed, who had been hospitalised for further treatment and hyperbaric oxygen therapy. Twenty-three patients with necrotising otitis externa were identified. The temporomandibular joint was involved in four patients (17 per cent); these patients showed a constant gradual improvement in C-reactive protein and were eventually discharged free of disease, except one patient who was lost to follow up. Four patients (16 per cent) without temporomandibular joint involvement died within 90 days of discharge, while all patients with temporomandibular joint involvement were alive. Three patients (13 per cent) without temporomandibular joint involvement needed recurrent hospitalisation including further hyperbaric oxygen therapy; no patients with temporomandibular joint involvement required such treatment. Patients with temporomandibular joint involvement had lower rates of recurrent disease and no mortality. Therefore, we suggest considering temporomandibular joint involvement as a positive prognostic factor in necrotising otitis externa management.

Acute otitis media is very general disease and concerns every child practically. The shortening the time of treatment as well as quick decrease of symptoms, and mainly the pain have large meaning in treatment of this disease. Combined treatment of fenspiride and typical treatment of otitis media permits as our investigations show on quicker and observed at children's larger number decrease of symptoms in children with acute otitis media. The aim of the study was to observe effectiveness of combined treatment with antibiotic and fenspiride in children with acute otitis media. The study comprised 40 children (mean age 8.2 years). The diagnosis of acute otitis media based on medical history data, otolaryngological examination and audiometry (tone and impedance). Children with GERD, hypersensitivity to amoxicillin and fenspiride as well as hypertrophy of adenoid were excluded from the study. Children were divided in two equal groups randomly. All children received amoxicillin in dose 80 mg/kg/day in three partite doses (Amotaks, Polfa Tarchomin Poland) as well as oxymethazolin 0.05% nasal drops 3 x day 1-2 drops (0.05% Nasivin, Merck Germany). In children from second group fenspiride was applied in dose 2 ml/kg/day in three divided doses (Eurespal, Servier Francja) additionally. Treatment was provided by 10 days. During the treatment parents made record of recession in 10 point scale, estimating following parameters: the pain of ear, bother, raised the temperature of body, loss of appetite, vomiting, diarrhea, otorrhea and crying. After end of treatment control otolaryngological and audiological examinations were performed. In studied children symptoms were similar, and the pain of ear was in both groups main suffering. Vomiting and diarrhea the most seldom were observed. In children with acute otitis media treated additionally with fenspiride statistically significant (p<0.01) quicker recession of clinical symptoms was observed. Statistically significant (p<0

From May 2008 to December 2013, 320 cases of otitis externa were diagnosed among 2012 dogs undergoing routine physical examinations at Celtic Creatures Veterinary Clinic, Sydney River, Nova Scotia for a diagnosis frequency of 15.9% [95% confidence interval (CI): 14.3% to 17.6%]. Twenty-four percent of these dogs exhibited 1 or multiple recurrences despite initial treatment with topical antimicrobial/anti-inflammatory solutions. The frequency of diagnosis was significantly higher in breeds with pendulous ears, but was not affected by ear hairiness. There were no seasonal patterns in the frequency of diagnosis. In clinical examination of 60 dogs with otitis externa, bacteria were evident in 47% of infections. Of 10 genera cultured, Staphylococcus spp. and diptheroids were most common. In this study, analysis of clinical records provided insights into the local prevalence of otitis externa and the efficacy of treatment in routine clinical situations. PMID:28216686

Toll-like receptors (TLRs) have a prominent role in inducing innate immune response. It has been suggested that regulation of TLRs is involved in the pathogenesis of chronic otitis media. TLR 2 and TLR 4 polymorphisms were connected with susceptibility to acute otitis and chronic otitis with effusion. The objective of this study was to establish expression of TLR 2 and 4 on middle ear mucosa in different types of chronic suppurative otitis media (CSOM), and the influence of gene polymorphisms TLR 2 Arg753Gln and TLR 4 Thr399Ile and Asp299Gly to susceptibility to CSOM. Middle ear mucosa and full blood samples were obtained from 85 patients with chronic suppurative otitis media with and without cholesteatoma. Control group for mucosal TLR expression consisted of 71 samples of middle ear mucosa taken from patients with otosclerosis, and control group for DNA polymorphism consisted of 100 full blood samples in healthy subjects. DNA polymorphism detection was done with restriction fragment length polymorphism in RT PCR. Expression of TLR 2 and 4 was determined with immunohistochemical staining. TLR 2 and TLR 4 expression on the middle ear mucosa was not influenced by age of the patients with chronic otitis media. Incidence of TLR 2 Arg753Gln polymorphism was significantly higher in patients with chronic otitis media, compared to control group. Significant association between TLR 2 Arg753Gln polymorphism and different types of mucosal changes in patients with chronic otitis media was established. TLR 2 and 4 expression on experimental group mucosa was significantly different compared to control group, where there was no expression (p=0.000). Strong dependence of TLR 2 and TLR 4 expression on middle ear mucosa with different mucosal changes and immunohistochemical activity after staining was detected. Certain polymorphisms in TLR genes could be indicative for susceptibility to chronic otitis media. Expression of TLR 2 and 4 on middle ear mucosa was more dependable on

Consequences of evolution: is rhinosinusitis, like otitis media, a unique disease of humans?

PubMed

Bluestone, Charles D; Pagano, Anthony S; Swarts, J Douglas; Laitman, Jeffrey T

2012-12-01

We hypothesize that if otitis media is most likely primarily a human disease due to consequences of evolution, rhinosinusitis may also be limited to humans for similar reasons. If otitis media, with its associated hearing loss, occurred in animals in the wild, they probably would have been culled out by predation. Similarly, if rhinosinusitis occurred regularly in animals, they likely would have suffered from severely decreased olfactory abilities, crucial for predator avoidance, and presumably would likewise have been selected against evolutionarily. Thus, both otitis media and rhinosinusitis-common conditions particularly in infants and young children-appear to be essentially human conditions. Their manifestation in our species is likely due to our unique evolutionary trajectory and may be a consequence of adaptations, including adaptations to bipedalism and speech, loss of prognathism, and immunologic and environmental factors.

Tuberculous otitis in infants: temporal bone histopathology and clinical extrapolation.

The study of infant temporal bones with tuberculosis (TB) of the middle ear and mastoid could provide information to assist with clinical diagnosis in this population. The TB pandemic has become a critical global public health problem. With the rising incidence of the disease, otolaryngologists might encounter an increased frequency of otologic TB. Pediatric temporal bone reports of TB are rare. Light microscopic examination was performed on both temporal bones from an infant who died as a result of miliary TB. The tympanic membranes were thickened with dilated blood vessels, yet were intact without perforations. Purulence, granulation tissue, and classic tubercles were observed in the middle ears and mastoids. Serous labyrinthitis and inflammatory cells surrounding the Cranial Nerve VIII in the internal auditory canal were observed in the inner ear. The histological findings suggest that a clinical presentation of infantile tuberculous otitis media and mastoiditis could be a patient with otoscopic findings consistent with common otitis media with an intact tympanic membrane, likely in conjunction with inner ear symptoms. Lacking the classic finding of multiple tympanic membrane perforations, tuberculous otitis might be underappreciated in this population.

There is an increased recovery of Fusobacterium necrophorum from cases of otitis media and mastoiditis in the pediatric population. These infections may be highly severe, causing local osteomyelitis, bacteremia, and Lemierre's syndrome. The severity and difficulties in providing optimal treatment for these infections may be especially difficult in this age group due to immunological immaturity and delayed presentation. In this review of literature, we present and analyze the clinical presentation, management, and outcome of otic infections caused by F. necrophorum in infants and young toddlers less than 2 years old. Search in Pubmed was conducted for reported cases in the English literature for the time period of the last 50 years. Twelve well-described cases were retrieved with F. necrophorum otitis and mastoiditis and complications reported in all cases. Treatment included both intravenously with antimicrobial agents (beta lactams plus metronidazole) and mastoidectomy. Lemierre's syndrome and Lemierre's syndrome variants developed in 60 % of the patients. Dissemination of the infection as distal osteomyelitis and septic shock were also reported. The outcome was favorable in all the cases. Otitis and mastoiditis infections in children less then 2 years old are invasive infections, and severe complications can occur.

Acute otitis media (AOM) is a common disease of childhood. AOM is most appropriately diagnosed by careful otoscopy with an understanding of clinical signs and symptoms. The distinction between AOM and chronic otitis media with effusion should be emphasized. Treatment should include pain management, and initial antibiotic treatment should be given to those most likely to benefit, including young children, children with severe symptoms, and those with otorrhea and/or bilateral AOM. Tympanostomy tube placement may be helpful for those who experience frequent episodes of AOM or fail medical therapy. Recent practice guidelines may assist the clinician with such decisions.

Distance education methods have taken on greater importance as medical student education has moved off campus into the community. What the best methods are for conveying information to students at distant sites has not been determined. To determine if students at distant community sites who received an otitis media study case by e-mail that was enhanced with a referral to a web-based otitis study case, performed better on otitis OSCE stations than students who received the same case not enhanced with visuals or referrals to a web-based otitis case. Students were randomized by community site to receive either the enhanced (E) or simple otitis study case (S). Students were e-mailed an otitis media study case during the 5th week of the rotation. Those randomized to the E-case received a case that started with a case scenario followed by a "Task" that instructed them to go to this web address: http://www.aap.org/otitismedia/www/vc/ear/index.cfm (American Academy of Pediatrics Otitis Web Site). They were then to select "Case 1" which was a continuation of the case scenario present on their e-mail. A list of learning objectives was also printed on the e-mail. Students receiving the S-case viewed the same case scenario and objectives, but were not instructed to go to the web-page. All students rotated through two OSCE otitis stations. In the first station they interviewed a simulated patient(OSCE-SP) and counseled her on the management of her 12 month old with otitis. Within that station they viewed a video of a pneumoscopic exam of two ears, one ear with otitis and the other ear normal. At the 2 nd otitis station the student presented the case to a faculty and was asked a series of questions about otitis media(OSCE-PR). Scores on the two stations were compared by group. There were 198 students who took the OSCE. 178 (90%) responded to a survey that indicated they had opened and read the e-mailed case. There were 87 students in the E-group and 91 in the S-group.

The Western Australian Pregnancy Cohort (Raine) Study recruited 2900 pregnant women from King Edward Memorial Hospital (KEMH) in Perth, Western Australia, between 1989 and 1991. Data from the children born were collected at both the Year 3 and Year 5 follow-up. At Year 3, n = 611 were diagnosed with recurrent otitis media through parent-report and clinical examination. At Year 5, n = 299 were considered exposed to otitis media based upon tympanometry results. Performance in the Child Behaviour Checklist (CBCL), a questionnaire completed by the primary caregiver at Year 10. Significant associations were found between recurrent otitis media at Year 3 and internalising behaviours (P = .011), and the somatic (P = .011), withdrawn (P = .014), attention (P = .003) and thought problems domains (P = .021), and the total CBCL score (P = .010). A significant association was also found between exposure to otitis media at Year 5 and externalising behaviours (P = .026).

The prevalence rate of chronic suppurative otitis media is high and its treatment continues to be a challenge for the otorhinolaryngologists. Due to middle ear infection, there may be pain, hearing loss and spontaneous rupture of the eardrum which results in perforation. Infections can cause a hole in the eardrum as a side effect of otitis media. The patients suffering from ear perforation or having a hole in eardrum require preventing entry of water in the ear. This article describes the development of ear cap using additive manufacturing and TRIZ (a collaborative tool) to prevent the entry of water in the ear during chronic otitis media.

Otitis media is a middle ear disease common in children under three years old. Otitis media can occur in normal individuals with no other symptoms or syndromes, but it is often seen in individuals clinically diagnosed with genetic diseases such as CHARGE syndrome, a complex genetic disease caused by mutation in the Chd7 gene and characterized by multiple birth defects. Although otitis media is common in human CHARGE syndrome patients, it has not been reported in mouse models of CHARGE syndrome. In this study, we report a mouse model with a spontaneous deletion mutation in the Chd7 gene and with chronic otitis media of early onset age accompanied by hearing loss. These mice also exhibit morphological alteration in the Eustachian tubes, dysregulation of epithelial proliferation, and decreased density of middle ear cilia. Gene expression profiling revealed up-regulation of Muc5ac, Muc5b and Tgf-β1 transcripts, the products of which are involved in mucin production and TGF pathway regulation. This is the first mouse model of CHARGE syndrome reported to show otitis media with effusion and it will be valuable for studying the etiology of otitis media and other symptoms in CHARGE syndrome.

Recent studies implicate microRNA 146 (miR-146) in regulation of inflammation via negative feedback of toll-like receptor signaling (TLR) in a wide variety of tissues, however its involvement in otitis media is unknown. Human middle ear epithelial cells were stimulated with proinflammatory cytokines, interleukin 1 beta or tumor necrosis factor alpha, for two to twenty-four hours. Middle ear biopsies were collected from children with otitis media with effusion (n = 20), recurrent otitis media (n = 9), and control subjects undergoing cochlear implantation (n = 10). miR-146a, miR-146b expression was assayed by quantitative PCR (qPCR). Expression of miR-146 targets involved in TLR signaling, IRAK1 and TRAF6, was assayed by qPCR in middle ear biopsies. Middle ear biopsies were cryosectioned and epithelial thickness measured by a certified pathologist. Proinflammatory cytokines induced expression of miR-146 in middle ear epithelial cells in vitro. Middle ear miR-146a and miR-146b expression was elevated in otitis media patients relative to control subjects and correlated with middle ear epithelial thickness. A trend towards inverse correlation was observed between miR-146 and TRAF6 expression in the clinical population. This report is the first to assess miRNA expression in a clinical population with OM. Findings herein suggest miR-146 may play a role in OM. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Craniofacial defects that occur through gene mutation during development increase vulnerability to eustachian tube dysfunction. These defects can lead to an increased incidence of otitis media. We examined the effects of a mutation in the Sh3pxd2b gene (Sh3pxd2bnee) on the progression of otitis media and hearing impairment at various developmental stages. We found that all mice that had the Sh3pxd2bnee mutation went on to develop craniofacial dysmorphologies and subsequently otitis media, by as early as 11 days of age. We found noteworthy changes in cilia and goblet cells of the middle ear mucosa in Sh3pxd2bnee mutant mice using scanning electronic microscopy. By measuring craniofacial dimensions, we determined for the first time in an animal model that this mouse has altered eustachian tube morphology consistent with a more horizontal position of the eustachian tube. All mutants were found to have hearing impairment. Expression of TNF-α and TLR2, which correlates with inflammation in otitis media, was up-regulated in the ears of mutant mice when examined by immunohistochemistry and semi-quantitative RT-PCR. The mouse model with a mutation in the Sh3pxd2b gene (Sh3pxd2bnee) mirrors craniofacial dysmorphology and otitis media in humans. PMID:21818352

To explore the views of children with cleft palate and their parents about daily life with otitis media with effusion and associated hearing loss. A qualitative study. Semistructured interviews were used to collect data from parents. Participatory techniques, including activities on a tablet computer, were used to collect data from children. Framework analysis was applied to interview transcripts. Two English cleft units. A purposive sample of parents of 37 children aged 0 to 11 years with experience of otitis media with effusion. Their children also took part if aged 6 to 11 years (n = 22). Themes related to the following: (1) emotions (frustration, anger, sadness, happiness, anxiety), (2) educational experiences (struggling at school, having to sit at the front of the class, requiring extra support, missing lessons for appointments or due to ear infections), (3) social interactions (isolation, communication, reliance on siblings, participation in activities). A number of areas of interviewees' everyday life were affected by the presence of otitis media with effusion. Parents may need to be forewarned about the possible ongoing nature of this condition and its impact on a child's social and emotional experiences. Children may also benefit from age-appropriate information about otitis media with effusion and its treatment, including information on hearing tests, to help reduce any anxiety.

Standard conservative treatment of exudative otitis media (EOM) was performed in 82 patients, but 44 of them received adjuvant fenspiride (erespal) in a dose 80 mg per os 3 times a day for 10 days. Dynamic pure tone audiometry, tympanometry and subjective response demonstrated higher treatment efficiency in the erespal group. Therefore, it is recommended to include erespal in combined conventional therapy of EOM.

The objective of the present study was to improve the effectiveness of medicamental therapy of exudative otitis media in the children with recurrent and chronic adenoiditis. It was shown that the use of fluifort (carbocysteine lysine salt) for the treatment of exudative otitis media in the children presenting with chronic adenoiditis is a more effective approach in comparison with the expectant management. It is concluded that the application of carbocysteine lysine salt in combination with the mometasone furoate nasal spray ensures the rapid elimination of the symptoms of adenoiditis and significantly accelerates the resolution of exudative otitis media compared with the monotherapeutic treatment.

Objective: Acute otitis media (AOM) causes an inflammatory response in the middle ear. We assessed differences in innate immune responses involved in bacterial defense at onset of AOM in children who were stringently defined as otitis prone (sOP) and children not otitis prone (NOP). Study Design: Innate immune genes analysis from middle ear fluid (MEF) samples of children. Methods: Genes of toll-like receptors (TLR), nod-like and retinoic acid-inducible gene-I-like receptors, downstream effectors important for inflammation and apoptosis, including cytokines and chemokines, were studied from MEF samples by using a real-time polymerase chain reaction array. Protein levels of differentially regulated genes were measured by Luminex. Results: Gene expression in MEF among children who were sOP was significantly different in upregulation of interleukin 8, secretory leukocyte peptidase inhibitor, and chemokine (C-C motif) ligand 3, and in downregulation of interferon regulatory factor 7 and its related signaling molecules interferon alpha, Toll-like receptor adaptor molecule 2, chemokine (C-C motif) ligand 5, and mitogen-activated protein kinase 8 compared with children who were NOP. Differences in innate gene regulation were similar when AOM was caused by Streptococcus pneumoniae or nontypeable Haemophilus influenzae. Conclusion: Innate-immune response genes are differentially regulated in children who were sOP compared with children with NOP. PMID:28124644

When symptoms of otitis media appear, parents and patients often access the Internet for health information. We study the content and quality of health information in parent-patient-focused websites for otitis media. We searched the 3 search engines (Google, Yahoo, and Bing) using "otitis media" and "middle ear infection" then reviewed the top 30 hits for each search. We included sites that were focused on providing patient-patient information about otitis media. A variety of instruments were used to assess website content and quality. In 35 included websites, there was considerable variation in content, with the average site having 11 out of 15 informational items potentially useful to parents and patients on otitis media (range 4-15). Across included websites, the mean DISCERN score was 47 out of 80 (low to medium quality), 16 (46%) were HONcode certified, and 8 (23%) fulfilled all the JAMA benchmark criteria. The average website was written at a 9th/10th-grade reading level. The content and quality of health information for otitis media in parent-and-patient-focused websites is highly variable. Although easy-to-read, high-quality websites with complete content are available, the average website sites is difficult to read without a high school education and is difficult to use. Consideration should be given to adopting a standard approach for presenting disease-specific information to parents and patients. © 2017 John Wiley & Sons Ltd.

Increased susceptibility to otitis media in a Splunc1-deficient mouse model

ABSTRACT Otitis media (inflammation of the middle ear) is one of the most common diseases of early childhood. Susceptibility to otitis is influenced by a number of factors, including the actions of innate immune molecules secreted by the epithelia lining the nasopharynx, middle ear and Eustachian tube. The SPLUNC1 (short palate, lung, nasal epithelial clone 1) protein is a highly abundant secretory product of the mammalian nasal, oral and respiratory mucosa that is thought to play a multifunctional role in host defense. In this study we investigated Splunc1 expression in the ear of the mouse, and examined whether this protein contributes to overall host defense in the middle ear and/or Eustachian tube. We found that Splunc1 is highly expressed in both the surface epithelium and in submucosal glands in these regions in wild-type mice. In mice lacking Splunc1, we noted histologically an increased frequency of otitis media, characterized by the accumulation of leukocytes (neutrophils with scattered macrophages), proteinaceous fluid and mucus in the middle ear lumens. Furthermore, many of these mice had extensive remodeling of the middle ear wall, suggesting a chronic course of disease. From these observations, we conclude that loss of Splunc1 predisposes mice to the development of otitis media. The Splunc1−/− mouse model should help investigators to better understand both the biological role of Splunc1 as well as host defense mechanisms in the middle ear. PMID:25765466

Clearance by the mucociliary system in 'simple chronic otitis media'.

PubMed

Hadas, E; Sadé, J

1979-08-01

This is a study of the rate of middle ear clearance in chronic otitis media and atelectatic ears. The clearance rate was measured with the aid of non-soluble saccharin, introduced into the middle ear through an existing perforation in 'chronic ears', or through a ventilating tube in atelectatic ears. Cholesteatomatous ears were excluded. Altogether 122 ears were examined and about two-thirds of the subjects felt the sweet taste in their mouths thereafter. The average time it took for the saccharin to be transported from the middle ear to the taste buds was 33' 22" minutes in non-infected (i.e. dry) chronic ears (38 patients or 66 per cent). Wet or infected ears with chronic otitis media (30 patients, or 58 per cent) showed a slower transport rate, averaging 54' 22" minutes--the difference was significant at the 0.01 level. 8 (63 per cent) of the atelectatic ears transported the saccharin at an average rate of 50' 25". This study demonstrated that most ears with 'simple' chronic otitis media and atelectatic ears have a patent eustachian tube and that their mucociliary system can transport foreign particles through it. When the ear is infected, transport tends to be slowed down.

Chronic otitis media (COM), affecting all over the world and in a wide range of age groups in Turkey, is an important cause of ear discharge and hearing loss. The main clinical manifestations are tympanic membrane perforation, ear, nose and throat problems. On the tympanic membrane perforation becomes persistent and cholesteatoma development, there are a lot of opinions today. Especially in the pathology associated with otitis media with effusion eustachian tube, it is known that COM and cholesteatoma develop. In our study, we interpreted 210 patients' temporal computed tomography (CT). Seventy of these 210 patients had otitis media with cholesteatoma, 70 patients had only otitis media without cholesteatoma, and 70 patients had no otitis media. The eustachian tubes were evaluated using temporal CT multiplanar reconstruction method. Angles with the horizontal plane of the eustachian tube and Reid and tubotympanic angles were measured. The angles between eustachian tube and horizontally oriented Reid plane of the patients with cholesteatoma were found to be significantly lower than the patients with otitis media without cholesteatoma and the patients with no history of otitis media. For the tubotympanic angle, no statistically significant differences were observed between the groups. These results suggest that the decrease in the angle with the horizontal plane of Reid in the eustachian tube in adults may play a significant role in the etiology of cholesteatoma.

Acute otitis media associated bilateral sudden hearing loss: case report and literature review.

PubMed

Smith, A; Gutteridge, I; Elliott, D; Cronin, M

2017-07-01

Sudden sensorineural hearing loss is a rare otological condition with potential for dire outcomes including permanent hearing loss. Although the majority of cases are deemed idiopathic, bilateral sudden sensorineural hearing loss represents a rare subset typically related to systemic conditions, with higher morbidity and mortality. A controversial association with acute otitis media has been reported, with few bilateral cases published in the literature. A very rare case of bilateral sudden sensorineural hearing loss associated with acute otitis media is described, with a review of the literature. The limited evidence available suggests that acute otitis media with tinnitus and/or bacterial pathology may have an increased risk of sudden sensorineural hearing loss, which is consistent with the case described. Although there is no sufficiently powered published evidence to provide definitive treatment guidelines, the literature reviewed suggests that early myringotomy and antibiotics may greatly improve treatment outcomes.

The objective of the present work was the clinical study of candibiotic exhibitic antibacterial, antimycotic, anti-inflammatory, and anesthetic properties when applied for the treatment of otitis externa and otitis media. This agent was included together with traditionally used systemic medications in the combined treatment of 26 patients. It was applied in the form of endoaural drops, transtubal administration through a catheter, and transtympanic pumping by the Politzer balloon technique (in case of perforation). In the patients with otomycosys, the preparation was used for the treatment of the external acoustic canal after the removal of fungal masses thrice daily for 1 month. Good clinical effect achieved in all the patients was manifest as the normal otoscopic picture and less frequent complaints on days 8-10 after the onset of therapy. Its maximum duration was 21 days. Positive dynamics (pain relief) was apparent within the first 2 days of the treatment. Fungal mycelium was absent after 14-16 days of the treatment in 100% of the patients initially presenting with yeast-like fungi.

The Japanese guidelines for acute otitis media in children recommend classifying acute otitis media by age, manifestations and local findings, and also recommend myringotomy for moderate-grade cases with severe local findings, severe-grade cases, and treatment-resistant cases. The heptavalent pneumococcal conjugate vaccine was released in Japan in February 2010. In Hiroshima City, public funding allowing free inoculation with this vaccine was initiated from January 2011, and the number of vaccinated individuals has since increased dramatically. This study investigated changes in the number of myringotomies performed to treat acute otitis media during the 5-year period from January 2008 to December 2012 at two hospitals and five clinics in the Asa Area of Hiroshima City, Japan. A total of 3,165 myringotomies for acute otitis media were performed. The rate of procedures per child-year performed in <5-year-old children decreased by 29.1% in 2011 and by 25.2% in 2012 compared to the mean rate performed in the 3 years prior to the introduction of public funding. A total of 895 myringotomies were performed for 1-year-old infants. The rate of myringotomies per child-year performed for acute otitis media in 1-year-old infants decreased significantly in the 2 years after the introduction of public funding for heptavalent pneumococcal conjugate vaccine compared to all years before introduction (p<0.000001). Our results suggest a benefit of heptavalent pneumococcal conjugate vaccine for acute otitis media in reducing the financial burden of myringotomy. In addition, this vaccine may help prevent acute otitis media with severe middle ear inflammation in 1-year-old infants.

Objective: To investigate the influencing factors of recurrent episodes of otitis media with effusion in children. Method: A retrospective summary of the clinical data of 210 cases of children with otitis media with effusion, 75 cases of recurrence after treatment, 135 cases were recovered, the recurrence of the related factors and after symptomatic treatment effect is analyzed. Result: Logistic regression analysis results found that adenoid hypertrophy (Ⅲ°, Ⅳ°), tonsil hypertrophy (Ⅳ°) and sinusitis (including choanal polyp), a positive allergens, upper respiratory tract infection, the stomach esophagus regurgitation, cleft palate, younger age has significant effect on recurrence of otitis media with effusion, have significant difference ( P < 0.05). And the influence of duration, gender, passive smoking history and previous medical history of otitis media with effusion has no obvious statistical significance ( P > 0.05). Through the comparison among different age groups, adenoidectomy Ⅲ °, Ⅳ ° hypertrophy tract infections in > 3-6 years old group has significant effect ( P < 0.05), recurrent respiratory tract infections in less than 3 years old group and the group of children aged > 3-6 years OME recurrence has significant effect ( P < 0.05). By tympanocentesis or tympanostomy tube insertion and according to different conditions to take symptomatic treatment, 75 cases (123 ears) were cured 96 ears (78.05%), 19 ears were improved (15.45%), the total effective rate was 93.50%, ineffective in 8 ears (6.50%). Conclusion: Adenoid hypertrophy (Ⅲ°, Ⅳ°), tonsil hypertrophy (Ⅳ°), sinusitis, nasal polyps, allergic diseases and upper respiratory tract infection gastroesophageal reflux, cleft palate and younger age may be adverse factors related to recurrent otitis media with effusion in children, the clinical doctors should pay attention to these symptoms, according to different causes, adopt individualized treatment plan, make children get the best

Acute leukemia is a well known childhood cancer. The relation between leukemia and otological symptoms has long been established but is highly rare as a debut symptom of leukemia. External otitis is a common condition affecting many children, and most cases are successively treated with topical medicine. Here we present a child with acute external otitis later shown to be the debut symptom of acute myeloid leukemia, to our knowledge the first specific case described. We have reviewed the literature to find red flags for suspicion of severe disease in case of acute external otitis. Copyright © 2018 Elsevier B.V. All rights reserved.

The objective of the present study was to clarify the characteristic pathognomonic features of middle ear lesions associated with tuberculosis and the approaches to their diagnostics under the present-day conditions. The study included 11 cases (18 ears) of tuberculosis otitis media and the related lesions of the mastoid process diagnosed with the use of clinical, roentgenological, cytological, bacteriological, pathomorphological, and molecular-genetic methods (including PCR diagnostics). The primary localization of tuberculosis in the middle ear was documented in 6 patients; in 5 patients, it was associated with pulmonary involvement. Five patients presented with smoldering exudative otitis media and the remaining six ones with suppurative perforating otitis media. The tuberculous process was diagnosed with the use of various methods including clinical examination, bacteriological (9%), cytological (27.3%), pathomorphological (18%) studies, and PCR diagnostics (55%). Diagnosis was made within a period from 1 month to 1.5 years after the application of the patients for medical assistance which suggests the difficulty of verification of tuberculous etiology of the disease of the middle ear. It is concluded that the high index of suspicion in the case of smoldering middle ear pathology facilitates its early diagnostics and successful treatment.

Acute otitis media: making sense of recent guidelines on antimicrobial treatment.

PubMed

Pichichero, Michael E; Casey, Janet R

2005-04-01

High-dose amoxicillin (80 to 90 mg/kg/d divided twice daily) remains the drug of choice for treatment of acute otitis media despite increasing antimicrobial resistance. For persistent or recurrent acute otitis media, guidelines recommend high-dose amoxicillin/clavulanate (90/6.4 mg/kg/d), cefdinir, cefprozil, cefpodoxime, cefuroxime, or ceftriaxone. Increasing the dose of amoxicillin does not cover infection with beta-lactamase-producing pathogens; add the beta-lactamase inhibitor clavulanate to amoxicillin, or choose a cephalosporin with good activity against S pneumoniae and good beta-lactamase stability. Key factors for enhancing compliance are taste of suspension, dosing frequency, and duration of therapy.

Allergy is considered as one of important etiologic factor of otitis media with effusion (OME). In present study, we evaluated the causal effect of allergy on OME in an animal model, and investigated the secondary effect of bacterial infection. Allergy and control animals were subdivided into groups with and without intratympanic injection of lipopolysaccharide (IT-LPS). Allergic otitis media was induced via intraperitoneal ovo-albumin injection with intranasal challenge. We assessed the occurrence of OME in allergic animals and the effect of IT-LPS on allergic otitis media. We also investigated the Th1 and Th2 responses in the middle-ear mucosa. Hearing of the animals was measured by ABR and DPOAE. OME was observed in 75% of the allergic animals. After IT-LPS, 100% of the control and allergy groups showed otitis media. Light microscopy revealed that the middle-ear mucosa of animals of both groups also was significantly increased after IT-LPS, and the Th1 response (IL-2 and IFN-γ) and Th2 response (IL-5 and IL-13) cytokines were expressed at higher levels in the allergy group with IT-LPS than in control group with IT-LPS. Hearing tests between the allergy and control group with IT-LPS did not reveal any differences. Our findings may be direct evidence of an allergic causal effect on OME. Th2 response cytokines were strongly expressed in allergic OME, and the inflammatory reaction to LPS was more intense in the allergic group, which indicates that otitis media related to allergy can be severely aggravated by an inflammatory reaction to bacterial infection.

The prevalence of otitis media in Greenlandic children is one of the highest in the world. International studies have shown that otitis-prone children may benefit from tubulation of the tympanic membrane. However, it is unknown whether these results can be applied to Greenlandic children and trials on the effects of ventilation tubes in high-risk populations have, to our knowledge, never been conducted. The trial is an investigator-initiated, multicentre, randomized, blinded superiority trial of bilateral ventilation tube insertion versus treatment as usual (no tube) in Greenlandic children aged 9-36 months with chronic otitis media with effusion or recurrent acute otitis media. With randomization stratified by otitis media subtype and trial site, a type 1 error of 5% and a power of 80%, a total of 230 participants are needed to detect a decrease of two visits to a health clinic during 2 years, which is considered the minimal clinical relevant difference. The primary outcome measure will be assessed blindly by investigating medical records. Secondary outcome measures are number of episodes of acute otitis media, quality of life, number of episodes of antibiotics administration and proportion of children with tympanic membrane perforations. This trial will provide evidence-based knowledge of the effects of ventilation tubes in children with middle ear infections from the high-risk Greenlandic population. Furthermore, this trial will improve the understanding of conducting randomized clinical trials in remote areas, where management of logistical aspects is particularly challenging.

Otitis externa is a common presentation to secondary care otolaryngology clinics. Despite this, few studies have investigated the microbiology and antimicrobial resistance of otitis externa. This study aimed to examine these issues. Analysis identified 302 swabs taken from 217 patients (100 male, 117 female), between 1 January 2015 and 30 March 2016, at our rapid access otolaryngology clinic. In total, 315 organisms were isolated; the most frequent was Pseudomonas aeruginosa (31.1 per cent), followed by candida species (22.9 per cent) and Staphylococcus aureus (11.7 per cent). P aeruginosa was sensitive to ciprofloxacin in 97.7 per cent of cases and to gentamicin in 78.4 per cent. Compared with studies worldwide, the relative proportions of different organisms causing otitis externa and the patterns of antimicrobial resistance differ. Increasing resistance of P aeruginosa to aminoglycosides demonstrates a changing pattern of antimicrobial resistance that has not been previously reported. Reassuringly, quinolone antibiotics remain highly effective when treating P aeruginosa.

Ten Year Study of the Stringently Defined Otitis Prone Child in Rochester, NY

2016-01-01

This review summarizes a prospective, longitudinal 10-year study in Rochester NY with virtually every clinically diagnosed acute otitis media (AOM) confirmed by bacterial culture of middle ear fluid. Children experiencing 3 episodes within 6 months or 4 episodes in 12 months were considered stringently-defined otitis prone (sOP). We found stringent diagnosis compared with clinical diagnosis reduced the frequency of children meeting the OP definition from 27% to 6% resulting in 14.8% and 2.4% receiving tympanostomy tubes, respectively. Significantly more often RSV infection led to AOM in sOP than non-otitis prone (NOP) children that correlated with diminished total RSV-specific serum IgG. sOP children produced low levels of antibody to Streptococcus pneumoniae and Haemophilus influenzae candidate vaccine protein antigens and to routine pediatric vaccines. sOP children generated significantly fewer memory B cells, functional and memory T cells to otopathogens following NP colonization and AOM than NOP children and they had defects in antigen presenting cells.

The goal of this study was to obtain representative Kenyan data on the point prevalence of acute otitis media (AOM) and its sequelae (otitis media with effusion [OME] and chronic suppurative otitis media [CSOM]), a major cause of preventable hearing loss in children in developing countries. In Africa, there are limited studies on the prevalence of AOM and its sequelae in children. Study subjects were children aged 2 to 15 years and were enrolled from randomly selected preprimary and primary schools. After parental or guardian consent, subjects had a questionnaire administered, otoscopy and tympanometry were done, and audiometry was performed on those with ear problems detected on these examinations. A total of 9825 (75%) children was from rural schools. The prevalence of CSOM was 15 of 1000, OME was 15 of 1000, and AOM was 7 of 1000 children. Rural Rift Valley schoolchildren had the highest prevalence of CSOM (24 of 1000) compared with other regions (12 of 1000; P < .0001). Ear discharge occurred before 3.5 years in 50% of 901 children with ear discharge. A history of ear discharge was associated with abnormal tympanograms (odds ratio [OR], 11.9-19.2) and mild-to-severe hearing loss (OR, 21.6-38.6), even in children without ear disease (OR, 10.7-24.4). The burden of AOM sequelae in Kenyan preschool and schoolchildren is significant, and it occurs mostly in the first 4 years of life. By preventing early recurrent AOM, pneumococcal vaccination might partly avert nonreversible sequelae. © The Author 2015.

Although tuberculosis can affect various organs and tissues, the lung is the site most commonly involved. Extrapulmonary tuberculosis (EPTB) involves relatively inaccessible and variable sites and is consequently often overlooked by clinicians. The ear is a notably very rare site of EPTB, and the diagnosis is difficult because of the variable and confusing signs and symptoms. To our knowledge, this is the first case in which tuberculous otitis media and endobronchial tuberculosis coexisted.

In a sample of 767 60-year-old men and 220 50-year-old men from the general population of Gothenburg, Sweden, the possible influence of otitis media, suffered in the past, on various measures of well-being was studied. Men with a history of otitis media required more medical care, measured as number of appointments with a doctor during the last 10 years, number of drugs taken during the last 14 days, and early retirement due to illness, than men with no such history. They also had lower grade of self-estimated perceived health, hearing, memory, physical fitness, appetite, mental energy and patience. There was no correlation between a history of otitis and a number of socio-economic factors. In addition, otitis infections in the past were measured as a hearing loss in the low-frequency range (greater than 20 dB loss in the 250 Hz and 500 Hz register). Such a hearing loss was related to the same variables as the otitis history. In addition, men with a low-frequency hearing loss were less well educated, were heavier, had more days and more periods of sickness benefit than other men. They also had spent more time as an in-patient in hospital and were less active during their leisure time. These results indicate that otitis infections affect the health and the well-being of the patients even long after the actual incident.

Nonencapsulated Streptococcus pneumoniae causes otitis media during single-species infection and during polymicrobial infection with nontypeable Haemophilus influenzae

Streptococcus pneumoniae strains lacking capsular polysaccharide have been increasingly reported in carriage and disease contexts. Since most cases of otitis media involve more than one bacterial species, we aimed to determine the capacity of a nonencapsulated S. pneumoniae clinical isolate to induce disease in the context of a single-species infection and as a polymicrobial infection with nontypeable Haemophilus influenzae. Using the chinchilla model of otitis media, we found that nonencapsulated S. pneumoniae colonizes the nasopharynx following intranasal inoculation, but does not readily ascend into the middle ear. However, when we inoculated nonencapsulated S. pneumoniae directly into the middle ear, the bacteria persisted for two weeks post-inoculation and induced symptoms consistent with chronic otitis media. During coinfection with nontypeable H. influenzae, both species persisted for one week and induced polymicrobial otitis media. We also observed that nontypeable H. influenzae conferred passive protection from killing by amoxicillin upon S. pneumoniae from within polymicrobial biofilms in vitro. Therefore, based on these results, we conclude that nonencapsulated pneumococci are a potential causative agent of chronic/recurrent otitis media, and can also cause mutualistic infection with other opportunists, which could complicate treatment outcomes.

Eustachian tube (ET) dysfunction may cause pathological changes in the middle ear, including recurrent acute otitis media and otitis media with effusion (OME). Mechanical obstruction of the ET may be caused by primary tumor-like lesions arising from ET or secondary ET infiltration due to nasopharyngeal and parapharyngeal space tumor. Tuberculosis is known to affect almost every organ in the body, and it should be a concern of each and every medical practitioner. However, tuberculosis of the ET has not been reported in the literature previously. This article reports primary tuberculosis arising in the ET that presented as aural fullness and hearing disturbance in a patient with OME. Copyright © 2015 Elsevier Inc. All rights reserved.

2017-10-01

Eczematous external otitis is a chronic inflammatory disease and often difficult to treat. Our objective was to investigate the clinical effect and in vitro antibacterial potential of medical honey eardrops as treatment of eczematous external otitis. In a prospective study, 15 patients diagnosed with recurrent eczematous external otitis were treated with medical honey eardrops for 2 weeks. The following clinical outcomes were evaluated: visual analog scale of ear complaints, score of eczema, and eradication of bacterial infection. Furthermore, the antibacterial effect of honey eardrops against different bacterial strains was tested in vitro. Treatment resulted in less discomfort and itching and decreased signs of eczema, with high patient satisfaction and without adverse reactions. Honey eardrops showed a strong in vitro inhibitory activity against all tested strains but did not eradicate Staphylococcus aureus infection in vivo. The results of this preliminary study indicate a possible role of honey eardrops in eczematous ear disease.

Cervical spinal tuberculosis with tuberculous otitis media masquerading as otitis externa malignans in an elderly diabetic patient: case report.

PubMed

Aderibigbe, A; Ologe, F E

Extrapulmonary manifestation of tuberculosis (Tb), a medieval disease, occurs in every part of the body with varying degree of frequency but commonly in the pleural and lymph nodes. When it occurs in bones thoracolumbar vertebrae is the usual site of involvement. Other bones are less involved hence seldomly reported. This is true for other organs and parts of the body including larynx, pharynx nose and the middle ear. More importantly, isolated extrapulmonary tuberculosis without pulmonary involvement is uncommon. The case of a 65 year old Nigerian trader who presented with headache, chronic ear ache with otorrhoea, persistent neck pain and found to be diabetic on further evaluation is presented. She was hitherto managed as a case of otitis external malignans without any improvement but rather her clinical condition worsened with evidence of cervical vertebra destruction and multiple cranial nerve palsies without pulmonary tuberculosis. Prompt and effective response to anti tuberculosis drugs informed the diagnosis of tuberculosis of the cervical vertebra and tuberculous otitis media with multiple cranial nerve palsies. This case underscores the value of high index of suspicion, thorough and complete clinical evaluation in any patient with chronic symptoms and signs unresponsive to conventional treatment.

Herbal medicines for treating acute otitis media: A systematic review of randomised controlled trials.

2017-12-01

This systematic review aimed to assess the clinical evidence for the widespread use of herbal medicines in treating acute otitis media. Eleven electronic databases, including MEDLINE, EMBASE, and the CENTRAL were searched, without language limitations. All randomised controlled trials involving the use of herbal medicines, alone or in combination with conventional therapies, for acute otitis media were included. We identified 4956 studies, of which seven randomised clinical trials met the inclusion criteria. The overall risk of bias of the included trials was relatively high or unclear. Treatment with Longdan-xiegan decoction or Shenling-baizhu powder, combined with antibiotics, appeared to be more effective than treatment with antibiotics alone in terms of the proportion of patients with total symptom recovery. Moreover, combination treatment of Sinupret ® and antibiotics facilitated the recovery of middle ear conditions and hearing acuity. Despite some indications of potential symptom improvement, the evidence regarding the effectiveness and efficacy of herbal medicine for acute otitis media is inconclusive due to the poor quality of trials included. Moreover, we only analysed seven trials in this review. Therefore, to properly evaluate the effectiveness of herbal medicine for acute otitis media, systematic reviews based on more rigorously designed randomized trials are warranted in the future.

2017-04-01

Placement of tympanostomy tubes for recurrent or chronic otitis media is the most commonly performed ambulatory procedure in the United States. Etiologies have been speculated to be environmentally based, and studies have suggested a genetic component to the disease. However, no large-scale studies have attempted to define a familial component. The objective of this study was to determine the familial risk of otitis media requiring tympanostomy tubes (OMwTT) in a statewide population. Retrospective observational cohort study with population-based matched controls. Using an extensive genealogical database linked to medical records, the familial risk of OMwTT was calculated for relatives of probands (46,249 patients diagnosed with OMwTT from 1996-2013) compared to random population controls matched 5:1 on sex and birth year from logistic regression models. The median age at time of tympanostomy tube placement was 1 year (interquartile range, 0-2 years). First-degree relatives of patients with OMwTT, primarily siblings, had a 5-fold increased risk of OMwTT (P < 10 -16 ). Second-degree relatives were at a 1.5-fold increased risk (P < 10 -15 ). More extended relatives (third, fourth and fifth degree) showed a 1.4-fold increased risk (P < 10 -15 ). In the largest population-based study to date, a significant familial risk is confirmed in OMwTT, suggesting otitis media may have a significant genetic component given the increased risk found in close as well as distant relatives. This could be influenced by shared environments given a five-times risk observed in siblings. Further understanding the genetic basis of OMwTT and its interplay with environmental factors may clarify the etiology and lead to better detection of disease and treatments. 3b.

Previously rare A2ML1 variants were identified to confer otitis media susceptibility in an indigenous Filipino community and in otitis-prone US children. The goal of this study is to describe differences in the middle ear microbiome between carriers and non-carriers of an A2ML1 duplication variant that increases risk for chronic otitis media among indigenous Filipinos with poor health care access. Ear swabs were obtained from 16 indigenous Filipino individuals with chronic otitis media, of whom 11 carry the A2ML1 duplication variant. Ear swabs were submitted for 16S rRNA gene sequencing. Genotype-based differences in microbial richness, structure, and composition were identified, but were not statistically significant. Taxonomic analysis revealed that the relative abundance of the phyla Fusobacteria and Bacteroidetes, and genus Fusobacterium were nominally increased in carriers compared to non-carriers, but were non-significant after correction for multiple testing. We also detected rare bacteria including Oligella that was reported only once in the middle ear. These findings suggest that A2ML1-related otitis media susceptibility may be mediated by changes in the middle ear microbiome. Knowledge of middle ear microbial profiles according to genetic background can be potentially useful for therapeutic and prophylactic interventions for otitis media and can guide public health interventions towards decreasing otitis media prevalence within the indigenous Filipino community.

Cultures obtained from pre-operative middle-ear swabs from patients with chronic otitis media have traditionally been used to guide antibiotic selection. This study investigated changes in the bacterial strains of the middle ear during chronic otitis media surgery. Pre-operative bacterial cultures of otorrhoea, and peri-operative cultures of the granulation tissue in either the middle ear or mastoid cavity, were obtained. Post-operative cultures were selectively obtained when otorrhoea developed after surgery. Bacterial growth was observed in 45.5 per cent of pre-operative cultures, 13.5 per cent of peri-operative cultures and 4.5 per cent of post-operative cultures. Methicillin-resistant Staphylococcus aureus was identified as the most common bacteria in all pre-operative (32.4 per cent), peri-operative (52.4 per cent) and post-operative (71.4 per cent) tests, and the percentage of Methicillin-resistant S aureus increased from the pre- to the post-operative period. The bacterial culture results for post-operative otorrhoea showed low agreement with those for pre-operative or peri-operative culture, and strain re-identification was required.

Acute septic arthritis of the temporomandibular joint derived from otitis media: a report and review of the English and Japanese literature.

Septic arthritis of the temporomandibular joint (SATMJ) is an extremely rare disease with characteristic features of preauricular pain, swelling, redness, and malocclusion. The present report describes a case of SATMJ derived from otitis media, which resulted in a good outcome. We also reviewed the English and Japanese literature with special interest in etiology. It is generally agreed that contiguous or distant infection and trauma are common etiological factors of SATMJ. So far, these etiological factors are mainly discussed based on hypotheses rather than sufficient evidence. Therefore, in many past cases, accurate causes were not identified. To our knowledge, our case is the third report of SATMJ following otitis media. In addition, this is the first case in which the pathogenic bacterium responsible for the otitis media was the definite cause of the SATMJ. Cases of SATMJ are sometimes misdiagnosed with otitis media, and SATMJ derived from otitis media is extremely rare. Dentists and otolaryngologists should collaborate for the management of this disease as needed.

To analyze the clinical features and the surgical treatment outcomes of patients with tuberculous otitis media and mastoiditis. The medical records of 16 patients (18 ears) with tuberculous otitis media and mastoiditis, who received surgery in Beijing Tongren hospital, were reviewed. The common symptoms were otorrhea and hearing loss, and 3 patients demonstrated severe sensorineural hearing loss. Three patients demonstrated a peripheral-type facial palsy. Temporal bone high resolution CT scans demonstrated the entire tympanum and mastoid air cells were occupied by soft tissue. Eleven patients demonstrated bone destruction and sequestra was found in 7 temporal bones. Contemporary pulmonary tuberculosis were diagnosed in 7 of the 16 patients. Surgical removal of disease lesions in combination with anti-tuberculosis treatment were given to 15 patients. Other than 2 cases of tuberculous otitis media and mastoiditis diagnosed by pre-operational biopsy through the perforated tympanic membrane, the remaining 14 cases were diagnosed intra-operatively or post-operatively. No relapse of tuberculosis in the middle ear and mastoid were found after follow-up for more than 1 year, except for the one case that was lost to follow-up. The 3 cases of facial nerve palsy almost recovered to normal. Clinicians should suspect tuberculous otitis media and mastoiditis if clinical findings include refractory otorrhea, total occupation of the tympanic cavity and mastoid ari cells by soft tissue, and erosion of the bone or sequestra as shown by CT. A history of tuberculosis should be asked carefully in order to differentiate tuberculous otitis media and mastoiditis. The patients who received surgery and anti-tuberculosis chemotherapy achieved more rapid healing of the ear.

In children, otitis media with effusion is treated using grommets or hearing aids. Parents considering treatment options express concerns regarding the psychosocial impact of hearing aids in terms of self-esteem and bullying. This study assessed the psychosocial impact of hearing aid use. A cross-sectional study was undertaken comparing hearing aid users to non hearing aid users with regard to their attitudes towards hearing aids. All subjects, who had been diagnosed with otitis media with effusion, were aged less than 16 years, were without disability and attended mainstream schools. A questionnaire was designed and utilised. The study comprised 47 children with hearing aids and 50 with grommets. Significant between-group differences (p < 0.05) were noted with regard to perceptions related to bullying, feelings of inadequacy and embarrassment. The overall negative perceptions of non hearing aid users were not reported by hearing aid users. Children with hearing aids do not suffer from bullying or low self-esteem to the extent perceived by parents. This information is useful for informed decisions regarding treatment of otitis media with effusion.

To reveal the success of boomerang-shaped chondroperichondrial graft (BSCPG) in pediatric chronic otitis media cases. A total of 43 pediatric patients (age 7-16 years) who had undergone type 1 tympanoplasty with the diagnosis of chronic otitis media between March 2010 and March 2013 were included in this retrospective study. The main outcome measures were the graft success rate and level of hearing improvement. Graft intake success rate was 90.7%. Mean preoperative and postoperative air-bone gap values were 20.51 ± 4.34 dB SPL and 9.32 ± 5.64 dB SPL, respectively (p < 0.001). Mean preoperative and postoperative pure tone average values were 28.6 ± 3.52 and 12.24 ± 5.22 respectively (p < 0.001). Air-bone gap was improved to ≤ 10 dB in 38 (88.37%) patients during the postoperative period. Boomerang-shaped chondroperichondrial grafting technique seems to be a successful alternative in the management of pediatric chronic otitis media cases. It has relatively higher grade graft success rate. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Streptococcus pneumoniae is an important cause of otitis media in children. In this study we estimated the effect of routine childhood immunization with heptavalent pneumococcal conjugate vaccine on frequent otitis media (3 episodes in 6 months or 4 episodes in 1 year) and pressure-equalizing tube insertions. The study population included all children who were enrolled at birth in TennCare or selected upstate New York commercial insurance plans as of July 1998 and continuously followed until 5 years old, loss of health plan enrollment, study outcome, or end of the study. We compared the risk of developing frequent otitis media or having pressure-equalizing tube insertion for 4 birth cohorts (1998-1999, 1999-2000, 2000-2001, and 2001-2002) by using Cox regression analysis. We used data from the National Immunization Survey to estimate the heptavalent pneumococcal conjugate vaccine uptake for children in these 4 birth cohorts in Tennessee and New York. The proportion of children in Tennessee and New York who received at least 3 doses of heptavalent pneumococcal conjugate vaccine by 2 years of age increased from < or = 1% for the 1998-1999 birth cohort to approximately 75% for the 2000-2001 birth cohort. By age 2 years, 29% of Tennessee and New York children born in 2000-2001 had developed frequent otitis media, and 6% of each of these birth cohorts had pressure-equalizing tubes inserted. Comparing the 2000-2001 birth cohort to the 1998-1999 birth cohort, frequent otitis media declined by 17% and 28%, and pressure-equalizing tube insertions declined by 16% and 23% for Tennessee and New York children, respectively. For the 2000-2001 to the 2001-2002 birth cohort, frequent otitis media and pressure-equalizing tubes remained stable in New York but increased in Tennessee. After heptavalent pneumococcal conjugate vaccine introduction, children were less likely to develop frequent otitis media or have pressure-equalizing tube insertions.

A 79-year-old man, with a history of well-controlled diabetes mellitus, presented with left-sided otalgia. With an initial diagnosis of simple otitis externa, he was discharged on topical drops. He represented 2 months later with worsening otalgia and discharge. A diagnosis of malignant otitis externa was made based on clinical and radiological findings. Intravenous Tazocin and Gentamicin were given based on previous bacterial culture from ear swabs. The patient failed to improve and developed left-sided facial nerve palsy. His condition stabilised following a change in antimicrobial therapy and his management continued in the community on intravenous Meropenem with twice weekly aural toilet. Repeated nuclear medicine imaging failed to demonstrate resolution. A bony sequestration was removed from the external auditory canal in the outpatient clinic, which following extended culture grew Scedosporium apiospermum; his management was subsequently changed to oral Voriconazole. This led to rapid clinical improvement and disease resolution over a 6 -week period. 2016 BMJ Publishing Group Ltd.

Quality of life is an important measure for health-outcome evaluation. Although otitis media is one of the most common childhood diseases, its impact on Portuguese children's quality of life is unknown. The aim of this study is to determine the quality of life of Portuguese children with chronic otitis media with effusion and/or recurrent acute otitis media and the short-term impact of transtympanic ventilation tubes, using the Portuguese version of the OM-6 questionnaire, a valid, reliable and sensitive instrument to evaluate the health-related quality of life in children with otitis media. This study was conducted in a tertiary referral center, to where children are referred from primary care and hospital pediatric consultations. The Portuguese version of the OM-6 questionnaire was applied to children with chronic otitis media with effusion and/or recurrent acute otitis media. The instrument was re-administered at two months postoperatively to a group of children who underwent tympanostomy tube placement, to evaluate the change in quality of life with the surgical procedure. The study involved a sample of 169 children, aged between 6 months and 12 years (mean: 4.20 ± 2.05 years). The average score in the survey was 3.3 ± 1.47, of a maximum of 7 (worst quality of life). The domains 'caregiver concerns', 'hearing loss' and 'physical suffering' had the highest scores. The domain 'hearing loss' was correlated with the domain 'speech impairment' (rs = 0.41; p < 0.001) and the domain 'physical suffering' correlated with the domain 'activity limitation' (rs = 0.47; p < 0.001). There was a correlation between the score on 'hearing loss' and the presence of conduction hearing loss (χ2 (6) = 24.662; p = 0.022). Children with chronic otitis media with effusion had lower scores on the domain 'physical suffering', while children with recurrent acute otitis media had lower scores in the domain 'hearing loss' and higher scores in the domain 'emotional distress'.

Otitis media is a well-known condition and its infra-temporal and intracranial complications are extremely rare because of the widespread usage of antibiotic treatment. We report a case of 63-year-old female with complaints of right-sided facial pain and diplopia. She had a history of acute otitis media before 4 months of admission to our neurology unit. Neurological examination showed that total ophthalmoplegia with ptosis, mydriasis, decreased vision and loss of pupil reflex on the right side. In addition, there was involvement of 5th and 7th cranial nerves. Neurological and radiological follow-up examinations demonstrated Jacod's Syndrome with unusual facial nerve damage and infection in aetiology. Sinusitis is the most common aetiology, but there are a few cases reported Jacod's Syndrome originating from otitis media.

BACKGROUND: Acute otitis media (AOM) is a common childhood illness and the leading indication for antibiotic prescriptions for US children. Xylitol, a naturally occurring sugar alcohol, can reduce AOM when given 5 times per day as a gum or syrup, but a more convenient dosing regimen is needed for widespread adoption. METHODS: We designed a pragmatic practice-based randomized controlled trial to determine if viscous xylitol solution at a dose of 5 g 3 times per day could reduce the occurrence of clinically diagnosed AOM among otitis-prone children 6 months through 5 years of age. RESULTS: A total of 326 subjects were enrolled, with 160 allocated to xylitol and 166 to placebo. In the primary analysis of time to first clinically diagnosed AOM episode, the hazard ratio for xylitol versus placebo recipients was 0.88 (95% confidence interval [CI] 0.61 to 1.3). In secondary analyses, the incidence of AOM was 0.53 episodes per 90 days in the xylitol group versus 0.59 in the placebo group (difference 0.06; 95% CI –0.25 to 0.13); total antibiotic use was 6.8 days per 90 days in the xylitol group versus 6.4 in the placebo group (difference 0.4; 95% CI –1.8 to 2.7). The lack of effectiveness was not explained by nonadherence to treatment, as the hazard ratio for those taking nearly all assigned xylitol compared with those taking none was 0.93 (95% CI 0.56 to 1.57). CONCLUSIONS: Viscous xylitol solution in a dose of 5 g 3 times per day was ineffective in reducing clinically diagnosed AOM among otitis-prone children. PMID:24394686

Eosinophilic otitis media (EOM) is a refractory disease characterized by the accumulation of eosinophils in middle ear effusion and mucosa. We summarize current knowledge regarding the clinical characteristics and management of EOM. Although eosinophil activation in inflamed foci is involved in the pathogenesis of EOM, little is known about the fate of the eosinophils and aftermath of their cell death. We discuss the possibility that eosinophils undergo non-apoptotic cell death that worsens tissue damage and increases effusion viscosity. Unlike chronic otitis media, EOM is strongly associated with an allergic background. Corticosteroids are currently the only effective pharmacological treatment, and surgical intervention is often required. Mucosal eosinophils infiltrate extensively into the middle ear cavity where they are stimulated by locally produced activators including interleukin-5 and eotaxin. The eosinophils undergo cytolysis in the effusion, which represents a major fate of activated eosinophils in vivo. Recent data revealed cytolysis could be renamed as extracellular trap cell death (ETosis). ETosis represents suicidal cell death involving total cell degranulation and development of sticky chromatin structures (extracellular traps (ETs)). The characteristics of eosinophil- and neutrophil-derived ET polymers might contribute to the difference in viscosity of secretions between EOM and common chronic otitis media. The extracellular products remaining after eosinophil ETosis are an important aspect of EOM pathology. The concept of ETosis also has novel implications for potential therapeutic modalities in various eosinophilic disorders.

Tuberculous otitis media -- a diagnostic dilemma.

Tuberculous otitis media can provide a diagnostic challenge even to the most astute and experienced clinician. The rarity of the condition and its propensity to masquerade as commoner otological conditions further delays diagnosis and treatment. We present the case of a 22-year-old female who presented with chronic aural discharge, unilateral hearing loss and recurrent hemifacial paralysis. The paper highlights the difficulty in diagnosis and stresses the need for a high index of suspicion in cases resistant to the common methods of treatment.

The study aimed to determine the prevalence and profile of otitis media in different parts of a city, i.e. non-slum urban areas, urban slums and rural areas. A door to door survey was conducted in identified areas of Delhi. A total of 3000 children (0-15 years) were randomly selected and examined for presence of otitis media. These children were equally distributed in the three areas under consideration. Data was analyzed to establish the prevalence of different types of otitis media. Chi-square test was then applied to compare disease prevalence among the three areas. 7.1% of the study population was identified with otitis media, which includes CSOM (4.26%), OME (2.5%) and ASOM (0.4%). In the non-slum urban parts of the city, 4.6% children had otitis media. This was significantly lower compared to 7% children in rural parts of Delhi and 9.9% in urban slums of the city. The prevalence of CSOM was considerably higher in slum areas (7.2%) as compared with rural (3%) and non-slum urban areas (2.6%). Ear infections are significantly more common in urban slums as compared to non-slum city areas and rural parts of Delhi. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Reduced Memory CD4+ T-Cell Generation in the Circulation of Young Children May Contribute to the Otitis-Prone Condition

PubMed Central

Sharma, Sharad K.; Casey, Janet R.

2011-01-01

Background. An explanation for the immunologic dysfunction that causes children to be prone to repeated episodes of acute otitis media (AOM) has long been sought. Poor antibody response has been associated with the otitis-prone condition; however, there is no precise mechanistic explanation for this condition. Methods. Non–otitis-prone and otitis-prone children with AOM or nasopharyngeal (NP) colonization caused by either Streptococcus pneumoniae or Haemophilus influenzae were compared for pathogen-specific CD4+ T-helper memory responses by stimulating peripheral blood mononuclear cells using 6 vaccine candidate S. pneumoniae and 3 H. influenzae protein antigens. Samples were analyzed by multi-parameter flow cytometry. Results. Significantly reduced percentages of functional CD45RALow memory CD4+ T cells producing specific cytokines (interferon γ, interleukin [IL]–2, IL-4 and IL-17a) were observed in otitis-prone children following AOM and NP colonization with either S. pneumoniae or H. influenzae. Immunoglobulin (Ig) G responses to the studied protein antigens were reduced, which suggests that antigen-specific B-cell function may be compromised as a result of poor T-cell help. Staphylococcal enterotoxin B stimulated similar cytokine patterns in memory CD4+T cells in both groups of children. Conclusions. Otitis-prone children have suboptimal circulating functional T-helper memory and reduced IgG responses to S. pneumoniae or H. influenzae after colonization and after AOM; this immune dysfunction causes susceptibility to recurrent AOM infections.

In order to assess the association between gene polymorphisms and otitis media (OM) proneness, tumor necrosis factor alpha (TNFA) -308, interleukin (IL) 10-1082 and -3575, IL6 -597, IL2 -330, and CD14 -159 genotyping was performed in 58 OM-prone children and 85 controls who were exposed to similar number and frequency of environmental and host risk factors. The frequencies of genotypes (wild type vs. genotypes containing at least one polymorphic allele) were not significantly different between groups, except for IL10 -1082. Polymorphic genotypes IL10 -1082 GA and GG were more frequent in OM-prone children than in control group (RR 1.145, 95 % CI 1.011-1.298; p = 0.047). However, logistic regression did not confirm IL10 -1082 polymorphic genotypes as an independent risk factor for OM proneness. The present study indicates that high-producing IL10 -1082 GA/GG genotypes may increase the risk for OM proneness in its carriers when exposed to other environmental/host risk factors (day care attendance, passive smoking, male sex, respiratory infections, and atopic manifestations). This study revealed no significant independent genetic association, but the lack of breastfeeding in infancy was found to be the only independent risk factor for development of OM-prone phenotype, implying that breastfeeding had a protective role in development of susceptibility to OM. • The pathogenesis of OM is of multifactorial nature, dependent on infection, environmental factors, and immune response of the child. • Cytokines and CD14 play an important role in the presentation and clinical course of otitis media, but a clear link with otitis media proneness was not established. What is new: • This is the first clinical and genetic study on Montenegrin children with the otitis media-prone phenotype. • The study revealed that high-producing IL10 -1082 genotypes may influence otitis media proneness in children exposed to other environmental/host risk factors.

To survey long-term hearing outcomes and middle ear pathology in a 30-year follow-up in individuals with onset of recurrent acute otitis media (rAOM) before three years of age. 28 adults, aged 30.1-31.8 years, who originally - at the age of 12-32 months - participated in a study on rAOM between 1979 and 1983, were re-examined regarding self-reported ear problems, current tympanic membrane changes and audiology. Thirteen subjects had suffered from rAOM during early childhood and 15 subjects served as a control group. Recurrent acute otitis media subjects reported hearing problems comparable to those of the controls. Pure tone audiometry, at 125-8000 Hz, did not differ between groups. The rAOM group had a trend for impaired high-frequency (9000-14,000 Hz) threshold levels (9000-14,000 Hz); implying that their cochlear function seemed to have deteriorated. Adults, who suffered from recurrent acute otitis media as infants, did not show any clinically significant hearing loss for pure tone audiometry when compared to controls, but there was a trend for impaired results regarding extended high frequency audiometry (9-14 kHz). Children suffering from rAOM will be at low risk of developing hearing loss and severe middle ear disease.

2011-10-01

The aim of this study was to investigate the possible correlation between otitis media with effusion, bad sucking habits and atypical swallowing in children affected by otitis media with effusion. 65 children, aged from 7 to 12 years, observed in the ENT Department of the "La Sapienza" University of Rome, were enrolled in the study group (group A). All children were affected by otitis media with effusion for more than 3 months. As control group, 60 healthy children, aged from 7 to 12 years were identified (group B). All the children underwent medical history, with evaluation of the sucking habits, ENT examination, tympanometry, orthodontic examination and evaluation of swallowing. In the orthodontic examination the variables analyzed were: maximum mouth opening, right and left mandibular lateral movements and mandibular protrusion. Atypical swallowing was considered to occur when lip activity produced strong tension in the perioral musculature, and/or the tip of the tongue was placed or pushed against the anterior teeth during swallowing. In the group A, atypical swallowing was found in 33/65 subjects out of the 65 children (50.7%). In the control group (group B) 16/60 children (26.6%) showed atypical swallowing. Compared with group B, deleterious sucking habits were significantly higher (p<0.05) in the study group (28/65 vs. 12/60). In both the study and control group, deleterious sucking habits were present in almost all children with atypical swallowing (28/33 in group A and 12/16 in group B). Our data suggest a correlation between otitis media with effusion, deleterious sucking habits and prevalence of atypical swallowing. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Tuberculous otitis media is a rare cause of chronic suppurative infection of the middle ear and mastoid. Patients typically have chronic tympanic membrane perforation and ear discharge associated with progressive, profound hearing loss, and resistance to antibiotic treatment. Diagnosis is often delayed by a low clinical suspicion, thus leading to complications such as irreversible hearing loss and facial nerve paralysis. Histological examination of a biopsy specimen reveals tuberculous changes. The disease is treated with antituberculosis agents.

Gradenigo's Syndrome in a Patient with Chronic Suppurative Otitis Media, Petrous Apicitis, and Meningitis.

PubMed

Taklalsingh, Nicholas; Falcone, Franco; Velayudhan, Vinodkumar

2017-09-28

BACKGROUND Gradenigo's syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo's syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo's syndrome presenting with meningitis on a background of chronic suppurative otitis media (CSOM) and petrous apicitis (apical petrositis). CASE REPORT A 58-year-old male African American presented with headaches and confusion. Magnetic resonance imaging (MRI) of the head showed petrous apicitis with mastoiditis and abscess formation in the cerebellomedullary cistern (cisterna magna). The case was complicated by the development of palsy of the fourth (trochlear) cranial nerve, fifth (trigeminal) cranial nerve, and sixth (abducens) cranial nerve, with radiological changes indicating infection involving the seventh (facial) cranial nerve, and eighth (vestibulocochlear) cranial nerve. Cerebrospinal fluid (CSF) culture results were positive for Klebsiella pneumoniae, sensitive to ceftriaxone. The patient improved with surgery that included a left mastoidectomy and debridement of the petrous apex, followed by a ten-week course of antibiotics. Follow-up MRI showed resolution of the infection. CONCLUSIONS This report is of an atypical case of Gradenigo's syndrome. It is important to recognize that the classical triad of Gradenigo's syndrome, suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve, may also involve chronic suppurative otitis media (CSOM), which may lead to involvement of other cranial nerves, petrous apicitis (apical petrositis), and bacterial meningitis.

Endoscopy-Assisted Ear Surgery for Treatment of Chronic Otitis Media With Cholesteatoma, Adhesion, or Retraction Pockets.

The objective of this study was to analyze the results of endoscopy-assisted ear surgery for the treatment of chronic otitis media with cholesteatoma, adhesion, or retraction pockets.Fifty-one patients who underwent oto-endoscopy-assisted canal wall up tympanomastoid surgery and/or limited anterior atticotomy with tympanoplasty for chronic otitis media with cholesteatoma, adhesion, or retraction pocket from 2006 to 2013 have been included in this study. Eradication of the disease from the middle ear and mastoid air cells was achieved by combination of the oto-microscobic and oto-endoscopic approaches. Second look surgery was performed 18 months later from the initial surgery in selected patients. Age, gender, pre-/postoperative otoscopy findings/audiograms, type of the used prostheses, and follow-up time were obtained from the patient's file. Anatomic integrity rates of the tympanic membrane, the mean gains of air bone gap, on pure-tone audiogram at 4 frequencies and existence of the residual disease were reviewed parameters. Functional evaluation was made in patients with intact tympanic membrane.Of the 51 patients, the ratios of the chronic otitis media with cholesteatoma and isolated adhesive otitis or retraction pocket cases were 74.5% (38/51) and 25.5% (13/51), respectively. Ossicular chain reconstruction was made with PORP in 27 patients and TORP in 20 patients, whereas the ossicular chain was intact in 4 patients. Anatomic integrity rates of the tympanic membrane were 90.2% (46/51). The overall (n = 46) pre-/postoperative mean ABG obtained at 4 frequencies were 28.3 ± 12.26 and 9.18 ± 5.68 dB (P < 0.0001) respectively. Residual cholesteatoma rate was 10.5% (34/38) for chronic otitis media with cholesteatoma patients. However, there was no recurrence or new cholesteatoma formation in isolated retraction pockets or adhesive otitis patients.Oto-endoscopic eradication of the cholesteatoma or epithelial tissue from hidden area after the all

Cellular Immune Response in Young Children Accounts for Recurrent Acute Otitis Media

Acute otitis media (AOM) is a common disease in young children. Streptococcus pneumoniae(Spn) and Haemophilus influenzae (NTHi) are the two most common pathogens that cause AOM. Over the past 5 years our group has been studying the immunologic profile of children that experience repeated AOM infections despite tympanocentesis drainage of middle ear fluid and individualized antibiotic treatment; we call these children stringently-defined otitis-prone (sOP). Although protection against AOM is primarily mediated by ototpathogen-specific antibody, our recent studies suggest that suboptimal memory B-& T- cell responses and an immaturity in antigen presenting cells may play a significant role in the propensity to recurrent AOM infections. This review focuses on the studies performed to define immunologic dysfunction in sOP children. PMID:24022464

Tuberculous otitis media is a rare disease. Due to the condition's rarity and its usually indolent course, the diagnosis is often delayed. This can lead to irreversible complications, such as permanent hearing loss or facial nerve paralysis. Tuberculosis of the middle ear cleft, as this disease's first presentation, is indeed very rare. Surgery may be carried out prior to diagnosis occasionally, i.e., middle ear exploration for chronic middle ear disease. We present four cases of tuberculous otitis media which occurred as the first presentation of the disease. The patients did not present with the classic symptoms of middle ear tuberculosis. The diagnosis was based on the histology following middle ear exploration for chronic middle ear disease. None of the patients presented any other systemic involvement. We present a review of this disease's clinical symptoms and the diagnostic tests available.

We treated 346 patients with otitis media with effusion (OME) and 30 (127 episodes) with recurrent acute suppurative otitis media at our outpatient clinic in the 6 years from October 1994 to September 2000. Of these, children under 15 years old numbered 185, mostly boys at a ratio of 1.4: 1.0, while patients aged 15 years or older numbered 161, mostly females at a ratio of 1.3: 1.0. In children, 24 were excluded due to a lack of diagnostic follow-up, 65 (40%) patients improved in conservative management of medication with and without repeated tubal inflation, 79 (49%) improved by paracentesis, and 18 (11%) recovered with the use of pressure equalization tubes (grommets). Of cases aged 15 years or older, follow-up was not possible in 28. Three (2%) were free of OME by conservative treatment, 116 (87%) improved by paracentesis, and 9 (7%) by using tubes. The mean durations of tube insertion was 11.3 months in children and 7.2 months in adults, but 5 adults (4%) continue being treated of this writing. Bilateral cases were 30% of children and 8% of adults with 73% of children affected bilaterally having persistence or recurrence. Acute purulent otitis media progressed to OME in 22% of children but only in 3% of patients aged 15 or older. In 36% of children and 26% of patients aged 15 or older, acute upper respiratory tract infection coincided with or predisposed to OME. Rhinosinusitis was seen in 19% of children and 14% of adults. Coincident allergic rhinitis was seen in 14% of children and 12% of adults with OME. Nasopharyngeal infection and allergy are likely related to OME development. The peak incidence of OME was similar to that of recurrent suppurative otitis media in children, so a seminal precipitating factor appears to result in these 2 conditions.

Tuberculosis is a rare cause of chronic suppurative otitis media and mastoiditis. Intracranial complications are rare. The authors report a case of a 14-year-old girl with chronic otitis media of her right ear for 2 years. Her presentation was as follows: 10 days before admission she had a high fever, headache, alteration of consciousness and a generalised seizure. CT scanning of her brain showed right otomastoiditis with early brain abscess of the right cerebellum. She underwent right radical mastoidectomy and aspiration of the cerebellar abscess. The pus from the mastoid and cerebellar abscess was stained positive for acid-fast bacilli (AFB). The pus culture grew Mycobacterium tuberculosis (MTB). Her discharge diagnosis was tuberculous mastoiditis (TM) with cerebellar abscess. Long-term treatment plans included antituberculous drugs for 1 year. PMID:22828175

Audiometry indicated a 35 dB conductive hearing loss at 0.5, 1 and 2 kHz with air–bone gaps of 12, 15 and 10 dB, respectively. A middle ear biopsy was performed under direct visualisation, with a middle ear lavage which was positive for allergic fungal sinusitis (AFS). The final diagnosis was tuberculous otitis media (TOM). Clinical symptoms and signs should be reviewed in every case of chronic otitis media keeping the possibility of tuberculosis in mind. Otorrhoea in a patient with known or suspected active pulmonary tuberculosis should be assumed to be TOM until proven otherwise. PMID:22798297

Background We report a case of bilateral malignant otitis externa complicated with bilateral petrous internal carotid artery pseudoaneurysms and their successful treatment with a flow diverter. Case report A 68-year-old woman with serious complications of type II diabetes mellitus had malignant otitis externa on the right side. She was treated with combined antibiotic therapy and underwent mastoidectomy for mastoiditis. She presented at our hospital with acute hemorrhage from the right external auditory canal. The emergency computed tomography (CT) angiography revealed a multiobulated pseudoaneurysm at the petrous segment of the right internal carotid artery. The pseudoaneurysm was treated with a 5 × 40-mm Surpass flow diverter. Three months later, she developed a malignant external otitis on the left side. As the infection progressed, a left-sided mastoiditis, a brain abscess, and a pseudoaneurysm at the petrous segment of the left internal carotid artery developed. The pseudoaneurysm caused bleeding from the left ear, and was treated with a 5 × 50-mm Surpass flow diverter. No recurrent bleeding was observed. Four months later, a follow-up angiography showed complete occlusion of the pseudoaneurysm on the left side, but a residual aneurysm could be detected on the right side. One year after the first intervention, the follow-up CT and magnetic resonance angiography revealed the complete occlusion of the aneurysms bilaterally. Conclusion The use of a flow diverter appears to be an efficient and safe method to occlude carotid pseudoaneurysms even in an inflammatory milieu.

Our group has an ongoing clinical research project investigating the immunology of the otitis-prone (OP) phenotype. In light of evidence that this condition arises from underlying immunological defects, we examined our sample population of stringently defined OP (sOP) children suffering 3 episodes of acute otitis media within 6 months or 4 within a year for a familial association with the sOP phenotype. We analyzed the frequency of sOP within and between families and the nasopharyngeal (NP) otopathogen colonization patterns within and between families. The presence of sOP siblings significantly predicted that additional children in the same family would likewise become sOP, with an odds ratio of 3.7 (95% CI 0.77-15.2, 95% lower bound 0.95). We further present evidence for an environmental contribution to this effect by means of prolonged exposure to otopathogens within family units. sOP children have a significant familial association. The tendency of siblings to share similar patterns of microbial NP colonization contributes to this association. Further research is necessary to determine whether and to what extent genetics are involved. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The case of a 5-year-old child diagnosed as having pervasive developmental disorder (PDD), autistic type, from age 1 is reported. After surgery of vegetation in middle ear for repetitive otitis, the child presented an improvement in autistic behaviours, previously expressed as impaired social interactions, qualitative abnormalities in communication, a marked delay in language development, echolalia, stereotypies and self-aggressive behaviours. The aim of this paper is to bring attention to occurrences of misdiagnosis of PDD, which can occur when an adequate screening of the autistic syndrome is not realised. The result of the surgery was an improvement in autistic behaviours, despite the persistence of less severe autistic traits that may be more closely related to Asperger’s syndrome. PMID:22736729

Tuberculous otitis media (TOM) is an uncustomary variety of tuberculosis (TB) usually seen secondary to pulmonary tuberculosis or associated with it. It is characterized by indolent and heterogeneous presentations. Diagnosis warrants clinical, radiological, and microbiological amalgamation. It is hence challenging and frequently delayed leading to disabling complications. Opportunate suspicion, timely diagnosis and appropriate antituberculosis therapy are the key to successful management. We report a unique case of bilateral TOM occurring in an immunocompetent adult.

Tuberculosis is a rare cause of chronic suppurative otitis media and mastoiditis. Intracranial complications are rare. The authors report a case of a 14-year-old girl with chronic otitis media of her right ear for 2 years. Her presentation was as follows: 10 days before admission she had a high fever, headache, alteration of consciousness and a generalised seizure. CT scanning of her brain showed right otomastoiditis with early brain abscess of the right cerebellum. She underwent right radical mastoidectomy and aspiration of the cerebellar abscess. The pus from the mastoid and cerebellar abscess was stained positive for acid-fast bacilli (AFB). The pus culture grew Mycobacterium tuberculosis (MTB). Her discharge diagnosis was tuberculous mastoiditis (TM) with cerebellar abscess. Long-term treatment plans included antituberculous drugs for 1 year.

In the limited number of Crohn disease cases involving the head and neck, there is a predilection for mucosal surfaces and rare reports of involvement in the postauricular region. To our knowledge, in all previously reported cases involving the head and neck, the patients had a known diagnosis of Crohn disease. This case describes a 10-year-old boy with a history of psoriasis and psoriasiform dermatitis who presented with bilateral chronic granulomatous otitis externa, obliteration of the external auditory canal, and fissuring, resulting in separation of the lobule from the preauricular skin. Pathologic examination results were consistent with granulomatous dermatitis concerning for cutaneous Crohn disease, and a subsequent gastroenterologic workup confirmed the diagnosis of Crohn disease. This is a report of chronic granulomatous otitis as the initial presentation of cutaneous Crohn disease in a child.

To study the extent to which otitis media (OM) in childhood is associated with adult hearing thresholds. Furthermore, to study whether the effects of OM on adult hearing thresholds are moderated by age or noise exposure. Population-based cohort study of 32,786 participants who had their hearing tested by pure-tone audiometry in primary school and again at ages ranging from 20 to 56 years. Three thousand sixty-six children were diagnosed with hearing loss; the remaining sample had normal childhood hearing. Compared with participants with normal childhood hearing, those diagnosed with childhood hearing loss caused by otitis media with effusion (n = 1255), chronic suppurative otitis media (CSOM; n = 108), or hearing loss after recurrent acute otitis media (rAOM; n = 613) had significantly increased adult hearing thresholds in the whole frequency range (2 dB/17-20 dB/7-10 dB, respectively). The effects were adjusted for age, sex, and noise exposure. Children diagnosed with hearing loss after rAOM had somewhat improved hearing thresholds as adults. The effects of CSOM and hearing loss after rAOM on adult hearing thresholds were larger in participants tested in middle adulthood (ages 40 to 56 years) than in those tested in young adulthood (ages 20 to 40 years). Eardrum pathology added a marginally increased risk of adult hearing loss (1-3 dB) in children with otitis media with effusion or hearing loss after rAOM. The study could not reveal significant differences in the effect of self-reported noise exposure on adult hearing thresholds between the groups with OM and the group with normal childhood hearing. This cohort study indicates that CSOM and rAOM in childhood are associated with adult hearing loss, underlining the importance of optimal treatment in these conditions. It appears that ears with a subsequent hearing loss after OM in childhood age at a faster rate than those without; however this should be confirmed by studies with several follow-up tests through

The tuberculosis of the ear is rare, and in most cases the clinical picture resembles that of a chronic otitis media. The diagnosis is often delayed, and this can lead to irreversible complications such as hearing loss and/or facial paralysis. In view of its rare occurrence, we report a case of primary tuberculous otitis media in a 87-year-old female patient. The diagnosis was made on the basis of both histological and microbiological findings. In particular, gene amplification techniques such as real-time polymerase chain reaction are useful method for rapid diagnosis and detecting tuberculous bacilli usually present at very low number. Early diagnosis is essential for the prompt institution of antituberculous therapy.

Tuberculosis (TB) is a rare cause of otitis media. This study aims to increase awareness on the clinical presentation of TB otitis media and illustrate how early detection affects treatment outcome. Chart review of 12 patients (13 ears) from a tertiary hospital in Manila, Philippines, seen from 2004 to 2009. Clinical predictors of the disease were summarized. Clinical, radiologic, and audiometric outcomes after treatment were compared between treatment groups. The 5 otoscopic presentations were multiple perforations, single perforation with refractory otorrhea and exuberant granulation tissue formation, single perforation with minimal otorrhea and no granulation tissue formation, intact tympanic membrane with middle ear effusion, and intact tympanic membrane with tumorlike tissue in the middle ear. Clinical predictors of the disease were history of pulmonary TB, work-related contamination of the infection, positive purified protein derivative test, positive chest radiographic finding and intraoperative granulation tissue with cheesy material, and temporal bone computed tomographic scan findings. Patients who had no middle ear surgery showed significantly better clinical, radiologic, and audiometric outcomes than those who were diagnosed late and had more complicated surgical procedure. The clinical presentation of TB otitis media is variable. Early detection of the early forms entail less surgical intervention and favors better treatment results.

The pathological picture may differ considerably between diagnostic subgroups of children with otitis media receiving ventilating tubes. The aims of this study are to investigate differences in quality of life among diagnostic subgroups of children treated with ventilating tubes and to investigate possible predictors for clinical success. Longitudinal observational study. Secondary care units. Four hundred ninety-one families were enrolled in the study. The Otitis Media-6 questionnaire was applied in the assessment of child quality of life. Caregivers completed questionnaires at 7 time points from before treatment to 18-month follow-up. Logistic regression analysis was used to investigate possible predictors for clinical success. Response rates ranged from 96% to 81%; diagnostic distribution: 15% recurrent acute otitis media (rAOM), 47% otitis media with effusion (OME), and 38% mixed diagnosis of rAOM and OME (rAOM/OME). There were no significant differences between children diagnosed with rAOM and children diagnosed with rAOM/OME. However, these children had a significantly poorer quality of life at baseline compared with children diagnosed with only OME. Factors associated with clinical success included a diagnosis of rAOM, number of interrupted nights, physician visits, and canceled social activities due to OM. Results highlight the importance of distinguishing between diagnostic subgroups of children having ventilating tube treatment. A diagnosis of rAOM was found to predict baseline quality of life. Children with rAOM with or without OME were found to suffer significantly more than children with only OME before treatment. Factors associated with disease severity were found to predict clinical success. © American Academy of Otolaryngology-Head and Neck Surgery Foundation 2015.

Efficacy of tildipirosin metaphylaxis for the prevention of respiratory disease, otitis and mortality in pre-weaned Holstein calves.

The aim of this study was to evaluate the efficacy of two metaphylactic approaches (long acting antibiotic injected once at 10 days of life or twice at 10 and 35 days of life) on the prevention of bovine respiratory disease (BRD), otitis and mortality in high-risk group-housed pre-weaned Holstein heifer calves. The antibiotic of choice for the metaphylactic approach was a long acting macrolide (tildipirosin) administered subcutaneously at the base of the neck at a dose of 1 mL per 45 kg body weight. A clinical trial was carried out on one dairy farm with random allocation of newborn calves to one of three treatments: (1) control (CTR); (2) one injection at 10 days of life (M1); and (3) two injections at 10 and 35 days of life (M2). Study heifers (n = 795) were reared in group pens of 25 calves per pen and fed unrestricted acidified non-saleable milk from day 1 to day 65 of life. Cox proportional hazard and general linear mixed models were used to evaluate the effect of treatment on mortality, BRD and otitis, and average daily weight gain. The birth weights, proportions of calves with inadequate transfer of passive immunity, proportions of calves born from primiparous dams and proportions of calves born from assisted parturitions were not different among CTR, M1 and M2 treatments. A significantly lower hazard of being affected with BRD and/or otitis (but not for BRD or otitis alone) was observed for M1 (hazard ratio, HR = 0.70, P = 0.009) and M2 (HR = 0.72, P = 0.01) when compared to the CTR group. Metaphylactic treatments had no effect on mortality, otitis and average daily weight gain during the pre-weaning period. Copyright © 2016 Elsevier Ltd. All rights reserved.

Otitis media is the most common reason U.S. children receive antibiotics. The requisite 7- to 10-day course of oral antibiotics can be challenging to deliver in children, entails potential systemic toxicity, and encourages selection of antimicrobial-resistant bacteria. We developed a drug delivery system that, when applied once to the tympanic membrane through the external auditory canal, delivers an entire course of antimicrobial therapy to the middle ear. A penta-block copolymer poloxamer 407–polybutylphosphoester (P407-PBP) was designed to flow easily during application and then to form a mechanically strong hydrogel on the tympanic membrane. U.S. Food and Drug Administration–approved chemical permeation enhancers within the hydrogel assisted flux of the antibiotic ciprofloxacin across the membrane. This drug delivery system completely eradicated otitis media from nontypable Haemophilus influenzae (NTHi) in 10 of 10 chinchillas, whereas only 62.5% of animals receiving 1% ciprofloxacin alone had cleared the infection by day 7. The hydrogel system was biocompatible in the ear, and ciprofloxacin was undetectable systemically (in blood), confirming local drug delivery and activity. This fast-gelling hydrogel could improve compliance, minimize side effects, and prevent systemic distribution of antibiotics in one of the most common pediatric illnesses, possibly minimizing the development of antibiotic resistance.

THE EFFECTS OF RADIATION THERAPY ON THE EAR WITH PARTICULAR REFERENCE TO RADIATION OTITIS MEDIA

DOE Office of Scientific and Technical Information (OSTI.GOV)

Borsanyi, S.J.

Between l957 and 1961 over l00 patients who were treated by a Co/sup 60/ teletherapy unit for malignant tumors of the head and neck were observed. The ears were included in the field of irradiation (4000 to 6000 r to the region of the inner ear). Between 50 and 60% of the patients developed ear symptoms during or shortly after completion of treatment. The most common symptoms were a sensation of fullness in the ear, some loss of hearing, earache, and tinnitus. Examination of ears revealed mild to moderate hyperemia of ear drums, with slight retraction in eariy stages andmore » bulging at iater stages. There was a moderate conductive hearing loss also. This disease entity is termed radiation otitis media and its pathophysiologic mechanism is similar to that of serous otitis media. Sterile fluid fills the middle ear, containing also some desquamated epithelial cells. Radiation otitis media usually clears up in a few weeks after the completion of treatment. In the management of this condition, vasoconstrictors, mild analgesics, and gentie politzeration were sufficient. However, in a few cases bacterial invasion of the sterile fluid occurred, resulting in purulent otitis media which required the use of antibiotics. Hearing of 20 patients was tested at weekly intervals during and after the completion of radiation. Cut of the 40 ears, 16 showed a conductive hearing loss, averaging 20 db. Six ears showed a worsening of the original loss of preceptive hearing. However, this was also primarily due to the development of a conductive component. There were no microscopicaiiy detectable immediate changes in the cochlea or labyrinth exposed to radiation in cancerocidal doses. (H.H.D.)« less

Patient: Male, 58 Final Diagnosis: Bacterial meningitis Symptoms: Altered mental status • headache • neck stiffness • vomiting Medication: — Clinical Procedure: — Specialty: Infectious Diseases Objective: Rare disease Background: Gradenigo’s syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo’s syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo’s syndrome presenting with meningitis on a background of chronic suppurative otitis media (CSOM) and petrous apicitis (apical petrositis). Case Report: A 58-year-old male African American presented with headaches and confusion. Magnetic resonance imaging (MRI) of the head showed petrous apicitis with mastoiditis and abscess formation in the cerebellomedullary cistern (cisterna magna). The case was complicated by the development of palsy of the fourth (trochlear) cranial nerve, fifth (trigeminal) cranial nerve, and sixth (abducens) cranial nerve, with radiological changes indicating infection involving the seventh (facial) cranial nerve, and eighth (vestibulocochlear) cranial nerve. Cerebrospinal fluid (CSF) culture results were positive for Klebsiella pneumoniae, sensitive to ceftriaxone. The patient improved with surgery that included a left mastoidectomy and debridement of the petrous apex, followed by a ten-week course of antibiotics. Follow-up MRI showed resolution of the infection. Conclusions: This report is of an atypical case of Gradenigo’s syndrome. It is important to recognize that the classical triad of Gradenigo’s syndrome, suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve, may also involve chronic suppurative otitis media (CSOM), which may lead to involvement of other cranial nerves, petrous apicitis

The antifungal activity of beta-thujaplicin was evaluated against 51 Malassezia pachydermatis strains isolated from canine ear canals with or without otitis externa. For comparison, sensitivity tests were performed on M. pachydermatis isolates for nystatin, ketoconazole, and terbinafine HCl, all clinically available antifungal agents. The minimal inhibition concentrations over 50% of the tested isolates (MIC50) were 3.13 microg/ml for beta-thujaplicin and nystatin, 0.016 microg/ml for ketoconazole, and 1.56 microg/ml for terbinafine HCl. The antifungal effect for M. pachydermatis of beta-thujaplicin compared favorably with commercial antifungal agents. None of the 51 M. pachydermatis isolates showed resistance against any of the tested antibiotics investigated in this study. Ten representative isolates of M. pachydermatis were subcultured for 30 generations at concentrations close to the MIC levels of beta-thujaplicin, nystatin, ketoconazole, and terbinafine HCl, and examined to determine whether they had acquired resistance to each drug. As a result, M. pachydermatis was found to achieve resistance more easily for ketoconazole and terbinafine HCl than for beta-thujaplicin or nystatin. The MIC50 of beta-thujaplicin did not change during the course of subculture, and it is thought that the potential development of a resistant strain is low, even with continuous infusion for otitis externa therapy. beta-Thujaplicin is an inexpensive and safe treatment with anti-inflammatory and deodorant effects that can be recommended as an effective remedy for canine otitis externa.

Identification of bacteria causing acute otitis media using Raman microspectroscopy

2016-03-01

Otitis media (OM) is the leading cause of acute physician visits and prescription of antibiotics for children. Current standard techniques to diagnose acute otitis media (AOM) are limited by their ability to probe only changes in symptoms of the bacterial infection that cause AOM. Furthermore, they are not able to detect the presence of or identify bacteria causing AOM, which is important for diagnosis and proper antibiotic treatment. Our goal is to detect the presence of and identify the pathogens involved in causing AOM based on their biochemical profile using Raman spectroscopy (RS). An inVia confocal Raman microscope (Renishaw) at 785 nm was used to detect bacteria causing AOM in vitro. The three main bacteria that cause AOM, Haemophilus influenzae, Moraxella catarrhalis, and Streptococcus pneumoniae were cultured in chocolate agar and Mueller-Hinton agar to determine which agar type would minimize Raman signal from the growth agar. Preliminary results identified specific Raman spectral features characteristic of S. pneumoniae. RS has the potential to accurately diagnose AOM, which will help in identifying the antibiotic that will be most beneficial for the patient and ultimately decrease the course of infection.

To detect the prevalence of fungus in chronic suppurative otitis media-cholesteatoma disease and to evaluate its clinical significance. Prospective observational study conducted in a sample size of 46 patients at a tertiary care university teaching hospital. Forty six patients suffering from chronic suppurative otitis media-cholesteatoma disease were recruited in this prospective study. Data was duly recorded. Cholesteatoma sample was procured at the time of mastoid surgery and microbiologically analysed for fungal infestation. Clinical correlation to fungus infestation of cholesteatoma was statistically analysed. Out of the recruited 46 patients, post-operatively cholesteatoma was seen in 40 cases only. Seventeen i.e. 42.5% of these cases had fungal colonization of cholesteatoma. Further a statistically significant correlation between persistent otorrhoea and fungal infestation of cholesteatoma was observed. Three cases of fungal otomastoiditis were also recorded in this study, but a statistically significant correlation between complications and fungus infestation of cholesteatoma could not be clearly established. There is fungal colonization of cholesteatoma which is pathogenic and can cause persistent otorrhoea. Copyright © 2017 Elsevier Inc. All rights reserved.

A control group who did not undergo BMT was also administered both the survey and OM-6 for comparison. Two hundred forty patients were enrolled (120 surgical patients and 120 controls). Logistic regression demonstrated age younger than 6 years old (P < .001), day care attendance (P < .001), and non-Hispanic Caucasian race (P = .022) to be associated with surgery. Surgical QOL outcomes demonstrated a significant improvement in otitis media-6 (OM-6) scores after surgical management from 3.00 (95% confidence interval [CI], 2.79-3.20) to 1.35 (95% CI, 1.22-1.47). In a universal health care model serving more than 2 million children, previously reported proxies of low SES as well as minority race/ethnicity were not associated with surgically managed otitis media contrary to reported literature. Caucasian race, young age, and day care attendance were associated with surgery. Surgery improved QOL outcomes 6 weeks postoperatively. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

Otitis media (OM) is an inflammatory or infectious disease of the middle ear. Acute otitis media (AOM) and otitis media with effusion (OME) are the two major types of OM. However, the tympanic membrane (TM) motion differences induced by AOM and OME have not been quantified in animal models in the literature. In this study, the guinea pig AOM and OME models were created by transbullar injection of Streptococcus pneumoniae type 3 and lipopolysaccharide, respectively. To explore the effects of OM on the entire TM vibration, the measurements of full-field TM motions were performed in the AOM, OME and untreated control ears by using scanning laser Doppler vibrometry (SLDV). The results showed that both AOM and OME generally reduced the displacement peak and produced the traveling-wave-like motions at relatively low frequencies. Compared with the normal ear, OME resulted in a significant change of the TM displacement mainly in the inferior portion of the TM, and AOM significantly affected the surface motion across four quadrants. The SLDV measurements provide more insight into sound-induced TM vibration in diseased ears. Copyright © 2016 Elsevier B.V. All rights reserved.

To compare the efficacy of two treatment regimens among Helicobacter pylori stool antigen positive children suffering from resistant otitis media with effusion. The study comprised 258 children with bilateral otitis media with effusion; 134 were positive for H pylori stool antigen, and were equally and randomly allocated to the control group or study group. The control group received standard otitis media with effusion therapy (amoxicillin and clavulanate), while the study group received standard H pylori triple therapy (clarithromycin, metronidazole and lansoprazole). In the control group, there was a marked clinical response to treatment in 33 of the 67 children (49.3 per cent). In the study group, there was a marked response in a significantly higher number of children (46 out of 67, 68.7 per cent). The 124 H pylori stool antigen negative children not included in the 2 aforementioned groups received amoxicillin and clavulanate, and a marked response in symptoms was evident in 98 of these children (79 per cent). H pylori infection may lead to resistance to traditional otitis media with effusion treatment in some cases. H pylori eradication is associated with a high cure rate.

Valuing reduced antibiotic use for pediatric acute otitis media.

Meropol, Sharon B

2008-04-01

The 2004 American Academy of Pediatrics acute otitis media guidelines urge parents to weigh the benefits of reduced antibiotic use, adverse drug events, and future resistance versus risks of extra costs and sick days resulting from guideline use. The value of decreased antibiotic resistance has not been quantified. The objective was to perform cost-utility analysis, estimating the resistance value of implementing the guidelines for acute otitis media treatment for children <2 years of age. Outcomes were described with a common denominator and the value of avoiding resistance was estimated using a parental perspective. Decision analysis results were used for outcome probabilities. Published utilities were used to describe outcomes in quality-adjusted life-day units. The minimum resistance benefit value, where the benefits of the American Academy of Pediatrics guidelines would at least balance their costs, was defined as the guidelines' incremental costs minus their other benefits. For a child 2 to <6 months of age presenting to a primary care physician with possible otitis media, parents would need to value the resistance benefit at 0.77 quality-adjusted life-days per antibiotic prescription avoided for the guidelines' benefits to balance their costs. For the 6- to <24-month-old group, results were 0.67 quality-adjusted life-days per prescription avoided. Results were sensitive to the dollar cost utility; when willingness to pay ranged from $20,000 to $200,000 per quality-adjusted life-year, results ranged from 0.36 and 0.30 quality-adjusted life-days up to 4.10 and 3.57 quality-adjusted life-days for the 2- to <6-month-old and 6- to <24-month-old groups, respectively. Costs were driven by missed parent work days. From a societal perspective, trading 0.30 to 4 quality-adjusted life-days to avoid 1 antibiotic course might be desirable; from a parental perspective, this may not be as desirable. Parent demand for antibiotics may be rational when driven by the value of

The usefulness of radionuclear scanning in the treatment of 18 patients with necrotizing progressive ''malignant'' external otitis is discussed. A Tc 99-m bone scan, a valuable test since results are positive in early cases of osteomyelitis of the temporal bone and base of skull, showed increased uptake in all 18 patients. In 6 patients, Ga-67 citrate scans were obtained at the start of therapy and at 5-6 week intervals thereafter. The serial gallium scans were useful in evaluating the effectiveness of therapy since the uptake decrease with control of infection.

Nontuberculous mycobacteria (NTM) are an increasingly recognized cause of chronic suppurative otitis media in children with tympanostomy tubes. Treatment of this condition is difficult and typically requires a combination of systemic antibiotics and surgical debridement. We present the first case of a 2-year-old male with chronic suppurative otitis media due to NTM who failed systemic antibiotic therapy and was successfully managed with topical boric acid powder. This report highlights the challenges involved in treating this infection, and introduces boric acid as a potentially valuable component of therapy. Copyright © 2015 Elsevier Ireland Ltd.

Several plants extracts from Mediterranean countries are traditionally employed in skin troubles both in humans and in animals. Malassezia pachydermatis is a lipophylic yeast responsible for otitis externa and dermatitis in dogs and for cutaneous and systemic disease in humans. Five mixtures of essential oils obtained from Mediterranean plants (Citrus paradisi, Salvia sclarea, Ocimum basilicum, Rosmarinus officinalis, Citrus limon, Anthemis nobilis, Lavandula hybrida and Thymus vulgaris) provided with antifungal and/or anti-inflammatory action assayed in vitro, were tested in vivo versus M. pachydermatis to treat once daily for 2 weeks 25 atopic dogs with Malassezia otitis externa. Mixture composed by C. limon 1%, S. sclarea 0,5%, R. officinalis 1%, A. nobilis 0,5% yielded excellent results in all treated dogs. Despite of clinical resolution after all treatments the number of blastospores did not decrease. This study confirms recent findings suggesting a multifactorial alternative approach for the management of canine Malassezia otitis.

The complications of otitis media (intra-cranial and extra-cranial) used to have a high morbidity and mortality in the pre-antibiotic era, but these are now relatively rare, mainly due to the use of antibiotics and the use of ventilation tubes, reducing the incidence of such complications significantly. Currently, an early suspicion of these complications is a major challenge for diagnosis and management. The cases of 5 patients (all male) are presented, who were diagnosed with complicated otitis media, 80% (4) with a mean age of 34.6 years (17-52). There was major comorbidity in 60% (3), with one patient with diabetes mellitus type 2, and two with chronic renal failure. There were 3 (60%) intra-cranial complications: one patient with thrombosis of the sigmoid sinus and a cerebellar abscess; another with a retroauricular and brain abscess, and a third with meningitis. Of the 2 (40%) extra-cranial complications: one patient had a Bezold abscess, and the other with a soft tissue abscess and petrositis. All patients were managed with surgery and antibiotic therapy, with 100% survival (5), and with no neurological sequelae. The clinical course of otitis media is usually short, limiting the infection process in the majority of patients due to the immune response and sensitivity of the microbe to the antibiotic used. However, a small number of patients (1-5%) may develop complications. Otitis media is a common disease in our country, complications are rare, but should be suspected when the picture is of torpid evolution with clinical worsening and manifestation of neurological signs.

In order to overcome the limitations inherent in current pharmacological treatments for Malassezia pachydermatis, the cause of otitis externa in dogs, the efficacy of a killer decapeptide (KP) was evaluated in vitro and in vivo. Sixteen dogs with naturally occurring M. pachydermatis otitis externa were enrolled, and the in vitro fungicidal activity of KP was evaluated using yeasts recovered from these animals. The therapeutic activity was evaluated in four groups of four animals each. The dogs were topically treated with KP (150 μl, 2 mg/ml) three times per week (group A) or every day (group B), treated with a scramble peptide every day (group C), or left untreated (group D). Assessment of clinical signs (pruritus, erythema, and lichenification and/or hyperpigmentation), expressed as mean of the total clinical index score (mTCIS), the population size of M. pachydermatis at the cytological examination (mean number of yeast cells at 40× magnification [mYC]), and culture testing (mean number of log10 CFU/swab [mCFU]), were conducted daily from the first day of treatment (T0) until two consecutive negative cultures (mCFU ≤ 2). KP showed an in vitro fungicidal effect against M. pachydermatis isolates, with an MFC90 value of 1 μg/ml. The mTCIS, mYC and mCFU were negative only in animals in group B after T8. Daily administration of KP for 8 days was safe and effective in controlling both clinical signs and the population size of M. pachydermatis causing otitis externa, thus offering an alternative to the currently available therapeutic or prophylactic protocols for recurrent cases of Malassezia otitis in dogs.

Background: Essential oils (EOs) are recommended by some veterinarians to treat otitis externa in pets, but data about their efficacy in scientific literature are very scant. Methods: Nine commercial EOs, from roman chamomile ( Anthemis nobilis L.), star anise ( Illicium verum ), lavender ( Lavandula hybrida ), litsea ( Litsea cubeba (Lour.) Pers.), basil ( Ocimum basilicum L.), oregano ( Origanum vulgare L. subsp. hirticum ), rosemary ( Rosmarinus officinalis L.), clary sage ( Salvia sclarea L.), and thyme ( Thymus vulgaris L.) were tested against bacterial and fungal pathogens previously isolated from dogs and cats with otitis externa. In particular, the analyses were carried out against Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus pseudointermedius , Aspergillus niger, Aspergillus fumigatus, Aspergillus terreus, Candida albicans, Candida tropicalis, Trichosporon sp., and Rhodotorula sp. Results: O. vulgare and S. sclarea showed superior antibacterial activity, even if not against all the strains. Trichosporon sp., C. albicans , and A. terreus were insensitive to most Eos, while other yeasts and molds showed different degrees of sensitivity. In particular, most fungi were inhibited by O. vulgare and R. officinalis . Conclusions: The obtained results suggest that some EOs could be included in treatment as an alternative therapeutic option in bacterial otitis complicated by fungi, in association with conventional drugs.

To analyse the clinical outcomes of biodegradable synthetic polyurethane foam versus ribbon gauze and ear wick in the treatment of severe acute otitis externa. Ninety-two adults with severe acute otitis externa were randomly assigned to groups receiving ear wick (n = 28), ribbon gauze (n = 34) or biodegradable synthetic polyurethane foam (n = 30). Clinical efficacy, in terms of otalgia, oedema, erythema and tenderness of the external auditory canal, was assessed before packing was applied and at follow up on the 3rd and 7th days of presentation. All packing materials were associated with improved otalgia and oedema on the 3rd day; however, there were significant differences between biodegradable synthetic polyurethane foam and the other packing materials, and there was no significant reduction in tenderness in the biodegradable synthetic polyurethane foam group on the 3rd day. In the ribbon gauze and ear wick groups, improvements in all clinical efficacy scores were statistically significant for all pairwise comparisons. The three packing materials were all quite effective in treating severe acute otitis externa, but ear wick and ribbon gauze were superior to biodegradable synthetic polyurethane foam for relieving signs and symptoms, especially on the 3rd day.

Chronic otitis media (COM) and associated hearing loss is a frequent problem for many Inuit children in Canada. In this study, we evaluated individuals aged 12-16 years living in Inukjuak, to determine the prevalence of middle ear disease and hearing loss, and the effect of hearing loss on academic performance. Otological examination, hearing test, medical and school file review were performed in November 1997. 88 individuals were seen. Otological examination revealed maximal scarring in 1.8%, minimal scarring in 34.9%, normal eardrums in 49.1% and chronic otitis media in 16.9%. There were 62 individuals whose ear exams could be directly compared with a previous exam done in 1987. Of those, there were three ears that had developed COM and 4/13 ears with COM in 1987 that had healed. Hearing tests found bilateral normal hearing in 80% (PTA <20dB), unilateral loss in 15% and bilateral loss in 5%. Hearing loss was associated with poorer academic performance in Language (p<.05). A similar trend was found in Mathematics but not in Inuttitut. Chronic otitis media remains a significant problem among the Inuit, with a prevalence of 16.9% in individuals aged 12-16 years. One in five in this age group has hearing loss, and this hearing loss impacts on academic performance.

Significant expression of macrophage migration inhibitory factor and its receptor (CD74) was observed in both the middle ear and inner ear in experimental otitis media in mice. Modulation of macrophage migration inhibitory factor and its signaling pathway might be useful in the management of inner ear inflammation due to otitis media. Inner ear dysfunction secondary to otitis media has been reported. However, the specific mechanisms involved are not clearly understood. The aim of this study is to investigate the expression of macrophage migration inhibitory factor and CD74 in the middle ear and inner ear in lipopolysaccharide-induced otitis media. BALB/c mice received a transtympanic injection of either lipopolysaccharide or phosphate-buffered saline (PBS). The mice were sacrificed 24 h after injection, and temporal bones were processed for polymerase chain reaction (PCR) analysis, histologic examination, and immunohistochemistry. PCR examination revealed that the lipopolysaccharide-injected mice showed a significant up-regulation of macrophage migration inhibitory factor in both the middle ear and inner ear as compared with the PBS-injected control mice. The immunohistochemical study showed positive reactions for macrophage migration inhibitory factor and CD74 in infiltrating inflammatory cells, middle ear mucosa, and inner ear in the lipopolysaccharide-injected mice.

The aim of this study was to evaluate antibacterial effects of PDT on common bacteria causing otitis media with effusion (OME). In vitro study was carried out using a hematoporphyrin derivative sensitizer (photogem) and 632 nm diode laser on H. influenzae, M. catarrhalis, and S. pneumoniae. One ml of each bacterial suspension was incubated for 3 hours and various concentrations of photogem were administered into the suspension. The suspensions were irradiated with 632 diode laser (15 J/cm2). The presence of colony forming units of the bacteria was examined, microscopic structures of bacteria were examined by TEM, and cytometry of bacteria was performed. The PDT was effective in killing all 3 kinds of bacteria. TEM showed damaged bacterial cell membrane and cytoplasmic structures and the flow cytometry showed lower number of viable bacteria in PDT group comparing to the control group. In vivo PDT study was performed using gerbil. S. pneumoniae or H. influenzae was injected into bullae. Photogem was injected into bullae in 2 days by when OME was developed and transcanal irradiation of 632 nm diode laser (90 J) was performed with a fiber perforated through an ear drum into a middle ear cavity and bulla. Four days after PDT, middle ear and bulla were washed with DPBS and the washed DPBS was cultured. The presence of bacterial colonies was examined. PDT was effective in killing S. pneumoniae in 87 % of the infected bullae with OME while it was effective to eradicate H. influenzae in 50 % of the infected bullae with OME. The results of these studies demonstrated that PDT may be effective to treat otitis media. It may have clinical implication to treat otitis media that is resistant to antibiotic therapy.

Conventional treatment for acute otitis media mainly targets bacteria with antibiotics, neglecting to control for mediators of inflammation. Mediators of inflammation, such as leukotrienes, have been identified in patients with acute otitis media (AOM) or subsequent secretory otitis media (SOM). They can cause functional eustachian tube dysfunction or increase mucous in the middle ear, causing persistent SOM following AOM. The objective of the present study was to evaluate whether or not administration of pranlukast, a widely used leukotriene C4, D4, and E4 antagonist, together with antibiotics could inhibit the progression to SOM. Children with AOM, who were from two to 12 years old, were randomly divided into two groups as follows: a control group in which 50 patients received antibiotic-based conventional treatment according to guidelines for treating AOM proposed by the Japan Otological Society (version 2006); and a pranlukast group, in which 52 patients were administered pranlukast for up to 28 days as well as given conventional treatment. Cases were regarded as persistent SOM when a tympanogram was type B or C2 four weeks after treatment was initiated. Two patients in the pranlukast group and 3 patients in the control group were excluded because they relapsed AOM within 28 days after initial treatment. Therefore, the analysis included 50 and 47 subjects in the pranlukast and control groups, respectively. The percentage of patients diagnosed with persistent SOM (22.0%) was significantly smaller in the pranlukast group compared with the control group (44.7%) (p = 0.018, chi-squared test). The results indicate that combined treatment of AOM with antibiotics and a leukotriene antagonist to control inflammation is useful for preventing progression to persistent SOM.

One hundred five infants and children with acute otitis media were randomized to therapy with loracarbef, an experimental carbacephem antibiotic, or amoxicillin-clavulanate (Augmentin), an approved drug for this disease. Ninety-two were evaluable (46 in each group). Middle ear fluid samples obtained for culture before therapy grew Haemophilus spp. in 30% of cases, pneumococci in 29% of cases, and Moraxella catarrhalis in 15% of cases. beta-Lactamase-producing bacteria were found in 37% of patients. Clinical failure occurred in four loracarbef-treated patients and one amoxicillin-clavulanate-treated patient (P = 0.361). Recurrence of acute otitis media was more common in the 2 to 3 weeks after loracarbef treatment (eight patients) than it was after amoxicillin-clavulanate therapy (three patients), but not significantly so (P = 0.197). Thus, combined failure and recurrence occurred in 12 loracarbef-treated patients and four amoxicillin-clavulanate-treated patients (P = 0.052). Gastrointestinal side effects occurred in 13 loracarbef-treated and 21 amoxicillin-clavulanate-treated patients (P = 0.13). Diaper rash was more common with amoxicillin-clavulanate (22 patients) than with loracarbef (10 patients; P = 0.016). Satisfactory results were achieved with both antibiotics, and adverse effects, although common, were minor. PMID:1854178

Otitis media is a frequent complication of a viral upper respiratory tract infection, and the reported co-incidence of those diseases increases with assay sensitivity and sampling density. We determined the incidence of otitis-media complications in young children when referenced to cold-like illnesses and to concurrent virus recovery from the nasopharynx. A total of 60 children from 24 families were followed from October 2003 through April 30, 2004, by daily parental recording of illness signs, weekly pneumatic otoscopic examinations, and periodic polymerase chain reaction assay of collected nasal fluids for common viruses. One hundred ninety-nine cold-like illnesses were observed, but a sample for virus assay was not collected concurrent with 71 episodes. Of the remainder, 73% of cold-like illnesses were temporally related to recovery of 1 or a combination of the assayed viruses, with rhinovirus predominating. For non-cold-like illness periods, 54 (18%) of 297 assays were positive for virus, and the virus frequency distribution was similar to that for cold-like illnesses. There were 93 diagnosed otitis-media episodes; 65 (70%) of these occurred during a cold-like illness. For the 79 otitis-media episodes with available nasal samples, 61 (77%) were associated with a positive virus result. In this population, the otitis-media complication rate for a cold-like illness was 33%. A cold-like illness was not a prerequisite for polymerase chain reaction detection of viruses in the nose and nasopharynx of young children. Viral detection by polymerase chain reaction in the absence of a cold-like illness is associated with complications in some subjects. Otitis media is a complication of viral infection both with and without concurrent cold-like illnesses, thus downwardly biasing coincidence estimates that use cold-based illnesses as the denominator.

Technetium99m Methylene Diphosphate bone scintigraphy (BS) of the skull was performed in three patients with malignant external otitis (MEO). Pathological uptake of the radioisotope in the mastoid region was found during the early stages of MEO updating radiologic findings. The extent of the radioisotope accumulation during the early stages of MEO indicates that the actual tissue damage exceeds the clinical estimation. The follow-up BS findings correlate well with the clinical course of MEO indicating either healing or extension to the base of skull.

Risk factors associated with chronic otitis media (COM) and recurrent otitis media (ROM) have been investigated in previous studies. The objective of this study was to integrate the findings and determine the possible risk factors for COM/ROM based on our meta-analysis. A comprehensive search of electronic bibliographic databases (PubMed, Embase, CNKI and Wanfang database) from 1964 to Dec 2012, as well as a manual search of references of articles, was performed. A total of 2971 articles were searched, and 198 full-text articles were assessed for eligibility; 24 studies were eligible for this meta-analysis. Regarding risk factors for COM/ROM, there were two to nine different studies from which the odds ratios (ORs) could be pooled. The presence of allergy or atopy increased the risk of COM/ROM (OR, 1.36; 95% CI, 1.13-1.64; P = 0.001). An upper respiratory tract infection (URTI) significantly increased the risk of COM/ROM (OR, 6.59; 95% CI, 3.13-13.89; P<0.00001). Snoring appeared to be a significant risk factor for COM/ROM (OR, 1.96; 95% CI, 1.78-2.16; P<0.00001). A patient history of acute otitis media (AOM)/ROM increased the risk of COM/ROM (OR, 11.13; 95% CI, 1.06-116.44; P = 0.04). Passive smoke significantly increased the risk of COM/ROM (OR, 1.39; 95% CI, 1.02-1.89 P = 0.04). Low social status appeared to be a risk factor for COM/ROM (OR, 3.82; 95% CI, 1.11-13.15; P = 0.03). Our meta-analysis identified reliable conclusions that allergy/atopy, URTI, snoring, previous history of AOM/ROM, Second-hand smoke and low social status are important risk factors for COM/ROM. Other unidentified risk factors need to be identified in further studies with critical criteria.

An upper respiratory tract infection (URTI) significantly increased the risk of COM/ROM (OR, 6.59; 95% CI, 3.13–13.89; P<0.00001). Snoring appeared to be a significant risk factor for COM/ROM (OR, 1.96; 95% CI, 1.78–2.16; P<0.00001). A patient history of acute otitis media (AOM)/ROM increased the risk of COM/ROM (OR, 11.13; 95% CI, 1.06–116.44; P = 0.04). Passive smoke significantly increased the risk of COM/ROM (OR, 1.39; 95% CI, 1.02–1.89 P = 0.04). Low social status appeared to be a risk factor for COM/ROM (OR, 3.82; 95% CI, 1.11–13.15; P = 0.03). Our meta-analysis identified reliable conclusions that allergy/atopy, URTI, snoring, previous history of AOM/ROM, Second-hand smoke and low social status are important risk factors for COM/ROM. Other unidentified risk factors need to be identified in further studies with critical criteria. PMID:24466073

Moraxella catarrhalis (Mcat) is a frequent pathogen of acute otitis media (AOM) in young children. Here we prospectively assessed naturally-induced serum antibodies to four Mcat vaccine candidate proteins in stringently defined otitis prone (sOP) and non-otitis prone (NOP) children age 6-36months old following nasopharyngeal (NP) colonization, at onset of AOM and convalescence from AOM. Serum IgG and IgM antibody against recombinant Mcat proteins, oligopeptide permease A (OppA), outer membrane protein (OMP) CD, hemagglutinin (Hag), and PilA clade 2 (PilA2), were quantitated by ELISA. During NP colonization by Mcat all four antigens were immunogenic in both sOP and NOP children. However, sOP children had lower antibody responses than NOP children across age 6-36months, similar to our findings for protein vaccine candidates of Streptococcus pneumoniae (Spn) and Nontypeable Haemophilus influenzae (NTHi). sOP children displayed a later and lower peak of antibody rise than NOP children for all four antigens during NP colonization of Mcat. The age-dependent increase of antibody ranked as OppA>Hag5-9>OMP CD>PilA2 in both sOP and NOP children. Lower serum antibody levels to the Mcat antigens were measured in sOP compared to NOP children at the onset of AOM. We did not find a consistent significant increase of antibody at the convalescence phase after an AOM event. sOP children is a highly vulnerable population that mount lower serum antibody responses to Mcat candidate vaccine proteins compared to NOP children during asymptomatic NP carriage and at onset of AOM.

External ear canal exostosis is more prevalent in northern coastal groups than in the highlands, suggesting that ocean activities facilitate the appearance of exostosis. However, southern coastal groups exposed to colder ocean water have a lesser incidence of exostosis, possibly due to less duration of exposure. There was a high incidence of otitis media in all groups of native population in Chile. One coastal group had a higher incidence, presumably due to racial factors. This is a paleopathological and paleoepidemiological study in temporal bones which assesses external ear canal exostosis and otitis media in prehistoric and historic native populations in Chile. A total of 460 temporal bones were evaluated for exostosis (ex) and 542 temporal bones were evaluated for otitis media (om). The study involved four groups: (1) Prehistoric Coastal (400-1000 AD) populations in Northern Chile (Pisagua-Tiwanaku) (22 temporal bones ex; 28 om); (2) Prehistoric Highland (400-1000 AD) populations in Northern Chile (292 temporal bones ex; 334 om); (3) Pisagua-Regional Developments (coastal) in Northern Chile (1000-1450 AD) (66 temporal bones ex; 82 om); and (4) Historic (1500-1800 AD) coastal populations in Southern Chile (80 temporal bones ex: 18 Chonos, 62 Fuegians. 98 om: 22 Chonos, 76 Fuegians). Skulls were evaluated visually and with an operating microscope. In addition, the otitis media group was evaluated with Temporal bone radiology - -lateral XRays-Schuller view - to assess pneumatization as evidence of previous middle ear disease. Prehistoric northern coastal groups had an incidence of exostosis of 15.91%, the northern highlands group 1.37%, and the southern coastal group 1.25%. There were changes suggestive of otitis media in: Pisagua/Tiwanaku 53.57%; Pisagua/Regional Developments 70.73%; Northern Highlands population 47.90%; Chonos 63.64%; and Fuegian tribes 64.47%.

To estimate acute otitis media incidence among young children and impact on quality of life of parents/caregivers in a southern Brazilian city. Prospective cohort study including children 0-5 years of age registered at a private pediatric practice. Acute otitis media episodes diagnosed by a pediatrician and impact on quality of life of parents/caregivers were assessed during a 12-month follow-up. During September 2008-March 2010, of 1,136 children enrolled in the study, 1074 (95%) were followed: 55.0% were ≤2 years of age, 52.3% males, 94.7% white, and 69.2% had previously received pneumococcal vaccine in private clinics. Acute otitis media incidence per 1000 person-years was 95.7 (95% confidence interval: 77.2-117.4) overall, 105.5 (95% confidence interval: 78.3-139.0) in children ≤2 years of age and 63.6 (95% confidence interval: 43.2-90.3) in children 3-5 years of age. Acute otitis media incidence per 1000 person-years was 86.3 (95% confidence interval: 65.5-111.5) and 117.1 (95% confidence interval: 80.1-165.3) among vaccinated and unvaccinated children, respectively. Nearly 68.9% of parents reported worsening of their overall quality of life. Acute otitis media incidence among unvaccinated children in our study may be useful as baseline data to assess impact of pneumococcal vaccine introduction in the Brazilian National Immunization Program in April 2010.

Pseudomonas aeruginosa is an opportunistic pathogen of the canine ear canal and occupies aquatic habitats in the environment. Nosocomial and zoonotic transmission of P. aeruginosa have been documented, including clonal outbreaks. The primary objective of this study was to assess various environmental exposures as potential risk factors for canine Pseudomonas otitis. It was hypothesized that isolates derived from infected ears would be clonal to isolates derived from household water sources and the mouths of human and animal companions of the study subjects. Seventy seven privately owned dogs with otitis were enrolled, along with their human and animal household companions, in a case-control design. Data on potential risk factors for Pseudomonas otitis were collected. Oral cavities of all study subjects, their human and animal companions, and household water sources were sampled. Pulsed field gel electrophoresis was used to estimate clonal relatedness of P. aeruginosa isolates. In a multivariate model, visiting a dog park was associated with 77% increased odds of case status (P = 0.048). Strains clonal to the infection isolates were obtained from subjects' mouths (n = 18), companion pets' mouths (n = 5), pet owners' mouths (n = 2), water bowls (n = 7) and water taps (n = 2). Clonally related P. aeruginosa isolates were obtained from dogs that had no clear epidemiological link. Genetic homology between otic and environmental isolates is consistent with a waterborne source for some dogs, and cross-contamination with other human and animal members within some households. © 2016 ESVD and ACVD.

To assess whether antimicrobial therapy in young children with acute otitis media reduces time to resolution of symptoms, overall symptom burden, and persistence of otoscopic evidence of infection. We used a cost-utility model to evaluate whether immediate antimicrobial treatment seems to be worthwhile, and if so, which antimicrobial agent is most cost effective. We compared the cost per quality-adjusted life-day of 5 treatment regimens in children younger than 2 years of age with acute otitis media: immediate amoxicillin/clavulanate, immediate amoxicillin, immediate cefdinir, watchful waiting, and delayed prescription (DP) for antibiotic. The 5 treatment regimens, listed in order from least effective to most effective were DP, watchful waiting, immediate cefdinir, immediate amoxicillin, and immediate amoxicillin/clavulanate. Listed in order from least costly to most costly, the regimens were DP, immediate amoxicillin, watchful waiting, immediate amoxicillin/clavulanate, and immediate cefdinir. The incremental cost-utility ratio of immediate amoxicillin compared with DP was $101.07 per quality-adjusted life-day gained. The incremental cost-utility ratio of immediate amoxicillin/clavulanate compared with amoxicillin was $2331.28 per quality-adjusted life-day gained. In children younger than 2 years of age with acute otitis media and no recent antibiotic exposure, immediate amoxicillin seems to be the most cost-effective initial treatment.

Staphylococcus caprae was originally isolated from goat milk. This uncommon coagulase-negative staphylococcus, usually associated with animals, has only infrequently been detected in human clinical specimens. Its association with acute otitis media has not been demonstrated so far. The study reports the first isolation of S. caprae from the middle ear fluid of a 12-month-old infant with recurrent, bilateral acute otitis media. Biochemical traits and susceptibility pattern of the isolated strain are also presented.

Bacterial intercellular communication, called quorum sensing, takes place via the production and collective response to signal molecules. In Gram-negative bacteria, like Pseudomonas aeruginosa, these signaling molecules are N-acylhomoserine lactones (AHLs). P. aeruginosa is a common cause of inflammation of the ear canal (otitis externa) in dogs. It employs quorum sensing to coordinate the expression of host tissue-damaging factors, which are largely responsible for its virulence. The treatment of P. aeruginosa-associated otitis is challenging due to a high intrinsic resistance of P. aeruginosa to several antibiotics. Attenuation of quorum sensing signals to inhibit bacterial virulence is a novel strategy for the treatment of resistant bacterial pathogens, including P. aeruginosa. Therefore, it is important to recognize and define quorum sensing signal molecules in clinical samples. To date, there are no reports on determination of AHLs in the veterinary clinical samples. The purpose of this study was to validate an analytical procedure for determination of the concentration of AHLs in the ear rinses from dogs with P. aeruginosa-associated otitis externa. Samples were obtained with rinsing the ear canals with physiological saline solution. For validation, samples from healthy dogs were spiked with none or different known amounts of the selected AHLs. With the validated procedure, AHLs were analyzed in the samples taken in weekly intervals from two dogs, receiving a standard treatment for P. aeruginosa-associated otitis externa. Validation proved that the procedure enables quantification of AHLs in non-clinical and clinical samples. In addition, a time dependent reduction of AHL concentration was detected for the treated dogs. Our results indicate that liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is superior in detecting AHLs compared to other chromatographic techniques. This is the first report on determination of AHLs in the clinical

Ectopic Mineralization and Conductive Hearing Loss in Enpp1asj Mutant Mice, a New Model for Otitis Media and Tympanosclerosis.

Otitis media (OM), inflammation of the middle ear, is a common cause of hearing loss in children and in patients with many different syndromic diseases. Studies of the human population and mouse models have revealed that OM is a multifactorial disease with many environmental and genetic contributing factors. Here, we report on otitis media-related hearing loss in asj (ages with stiffened joints) mutant mice, which bear a point mutation in the Enpp1 gene. Auditory-evoked brainstem response (ABR) measurements revealed that around 90% of the mutant mice (Enpp1asj/asj) tested had moderate to severe hearing impairment in at least one ear. The ABR thresholds were variable and generally elevated with age. We found otitis media with effusion (OME) in all of the hearing-impaired Enpp1asj/asj mice by anatomic and histological examinations. The volume and inflammatory cell content of the effusion varied among the asj mutant mice, but all mutants exhibited a thickened middle ear epithelium with fibrous polyps and more mucin-secreting goblet cells than controls. Other abnormalities observed in the Enpp1 mutant mice include over-ossification at the round window ridge, thickened and over-calcified stapedial artery, fusion of malleus and incus, and white patches on the inside of tympanic membrane, some of which are typical symptoms of tympanosclerosis. An excessive yellow discharge was detected in the outer ear canal of older asj mutant mice, with 100% penetrance by 5 months of age, and contributes to the progressive nature of the hearing loss. This is the first report of hearing loss and ear pathology associated with an Enpp1 mutation in mice. The Enpp1asj mutant mouse provides a new animal model for studying tympanosclerotic otitis and otitis media with effusion, and also provides a specific model for the hearing loss recently reported to be associated with human ENPP1 mutations causing generalized arterial calcification of infancy and hypophosphatemic rickets.

The clinical efficiency of treatment was evaluated in 60 patients aged 18 to 60 years with protracted acute otitis media (AOM) who had residual tympanic membrane inflammation and exudates in the tympanic cavity. The patients were divided into 2 groups of 30 each, who received equal basic medical treatment; Group 1 patients were additionally given eurespal (fenspiride) 80 mg thrice daily for 2 weeks. The patients were examined by clinical, endoscopic, and audiometric studies; the transport function of the nasal ciliated epithelium was also explored. The findings suggest the benefits of the additional use of eurespal in the treatment of the catarrhal stage of AOM.

Most Streptococcus pneumoniae strains are killed by very low concentrations of penicillin and other beta-lactam antibiotics, yet middle ear inflammation and effusion persist for days to weeks after treatment in most cases of pneumococcal otitis media. To study the effect of beta-lactam antibiotic treatment on pneumococci and the middle ear inflammatory response during pneumococcal otitis media, we measured concentrations of pneumococci, inflammatory cells, and lysozyme in middle ear fluid (MEF) by using the chinchilla model. Procaine penicillin G given intramuscularly 12 and 36 h after inoculation of pneumococci into the middle ear caused a significant acceleration in the MEF inflammatory cell concentration compared with that in untreated controls, with a significant peak in the inflammatory cell concentration 24 h after pneumococcal inoculation. The lysozyme concentration in MEF also increased more rapidly in treated than in control animals. Viable pneumococci were not detected in MEF after the second dose of penicillin, but the total pneumococcal cell concentration remained unchanged for at least 45 days. Therefore, penicillin treatment accelerated middle ear inflammation while killing pneumococci, but treatment did not accelerate clearance of the nonviable pneumococcal cells from MEF. Further studies will need to define the contribution of these responses to acute and chronic tissue injury. PMID:1563782

Although the inner ear has long been reported to be susceptible to middle ear disease, little is known of the inflammatory mechanisms that might cause permanent sensorineural hearing loss. Recent studies have shown inner ear tissues are capable of expressing inflammatory cytokines during otitis media. However, little quantitative information is available concerning cytokine gene expression in the inner ear and the protein products that result. Therefore, this study was conducted of mouse middle and inner ear during acute otitis media to measure the relationship between inflammatory cytokine genes and their protein products with quantitative RT-PCR and ELISA, respectively. Balb/c mice were inoculated transtympanically with heat-killed Haemophilus influenzae and middle and inner ear tissues collected for either quantitative RT-PCR microarrays or ELISA multiplex arrays. mRNA for several cytokine genes was significantly increased in both the middle and inner ear at 6 hours. In the inner ear, these included MIP-2 (448 fold), IL-6 (126 fold), IL-1β (7.8 fold), IL-10 (10.7 fold), TNFα (1.8 fold), and IL-1α (1.5 fold). The 24 hour samples showed a similar pattern of gene expression, although generally at lower levels. In parallel, the ELISA showed the related cytokines were present in the inner ear at concentrations higher by 2 to 122 fold higher at 18 hours, declining slightly from there at 24 hours. Immunohistochemistry with antibodies to a number of these cytokines demonstrated they occurred in greater amounts in the inner ear tissues. These findings demonstrate considerable inflammatory gene expression and gene products in the inner ear following acute otitis media. These higher cytokine levels suggest one potential mechanism for the permanent hearing loss seen in some cases of acute and chronic otitis media. PMID:25922207

Determinants of Change in Air-Bone Gap and Bone Conduction in Patients Operated on for Chronic Otitis Media.

Middle ear surgery aims to eliminate pathology from the middle ear, improve drainage and ventilation of the postoperative cavity, and reconstruct the tympanic membrane and ossicles. The aim of this work is to define the factors that affect ABG (air-bone gap) and bone conduction in the patients operated on due to chronic otitis media. A prospective analysis of patients operated on due to diseases of the middle ear during 2009-2012 was carried out. The cases of patients operated on for the first time due to chronic otitis media were analyzed. The analysis encompassed patients who had undergone middle ear surgery. The patients were divided into several groups taking into account the abnormalities of the middle ear mucous and damage of the ossicular chain observed during otosurgery. A significant hearing improvement was observed in patients with type 2 tympanoplasty in the course of chronic cholesteatoma otitis media and in patients with simple chronic inflammatory process in whom a PORP was used in the reconstruction. Granulation tissue was an unfavorable factor of hearing improvement following tympanoplasty. A significant improvement of bone conduction was observed in the patients with dry perforation without other lesions in the middle ear. The elimination of granulation lesions was a positive factor for the future improvement of the function of the inner ear. The presence of granuloma-related lesions in the middle ear spaces is likely to impede hearing improvement. Damage to the ossicular chain rules out the possibility of bone conduction improvement after surgery. The prognosis on tube-related simple chronic otitis media after myringoplasty, with the preserved continuity of the ossicular chain, consists of closing the ABG and leads to significant improvement of bone conduction.

Chronic otitis media (COM) is a widespread pathological condition that affects up to 2% of the general population. Certain forms of this disease markedly deteriorate the quality of life of the patients which makes them overestimate the severity of harm to their health status and can be a cause of inflated expectations as regards the results of the planned surgical treatment. The linking element between the patient's expectations and the outcomes of the surgical intervention may be the recently developed questionnaires for the evaluation of the health-related quality of life (HRQoL). One of them, the COMQ-12 questionnaire, was devised to estimate the subjective reports by the patients concerning the deterioration of their quality of life attributable to chronic otitis media. The objective of the present study was to characterize the value of the 5-point Russian-language version of COMQ-12 for the evaluation of each of its 12 items concerning various aspects of health based on the personal opinions of the patients suffering from chronic otitis media The study included 108 patients 49 of whom were men and 59 women (45% and 55% respectively) at the age varying from 16 to 84 years. The COMQ-12 scores, according to the reports of individual patients, ranged from 4 to 43 of the 60 ones possible. The average score was 19.4 (SD=8.3). The overall median COMQ-12 score was 20, and the mode scored 14. The Cronbach-alpha index was equal to 0.860. The Russian-language version of the COMQ-12 questionnaire provides a reliable tool for the estimation of the quality of life in the patients presenting with various forms of chronic otitis media.

Trends in broad-spectrum antibiotic prescribing for children with acute otitis media in the United States, 1998–2004

PubMed Central

Coco, Andrew S; Horst, Michael A; Gambler, Angela S

2009-01-01

Background Overuse of broad-spectrum antibiotics is associated with antibiotic resistance. Acute otitis media (AOM) is responsible for a large proportion of antibiotics prescribed for US children. Rates of broad-spectrum antibiotic prescribing for AOM are unknown. Methods Analysis of the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey, 1998 to 2004 (N = 6,878). Setting is office-based physicians, hospital outpatient departments, and emergency departments. Patients are children aged 12 years and younger prescribed antibiotics for acute otitis media. Main outcome measure is percentage of broad-spectrum antibiotics, defined as amoxicillin/clavulanate, macrolides, cephalosporins and quinolones. Results Broad-spectrum prescribing for acute otitis media increased from 34% of visits in 1998 to 45% of visits in 2004 (P < .001 for trend). The trend was primarily attributable to an increase in prescribing of amoxicillin/clavulanate (8% to 15%; P < .001 for trend) and macrolides (9% to 15%; P < .001 for trend). Prescribing remained stable for amoxicillin and cephalosporins while decreasing for narrow-spectrum agents (12% to 3%; P < .001 for trend) over the study period. Independent predictors of broad-spectrum antibiotic prescribing were ear pain, non-white race, public and other insurance (compared to private), hospital outpatient department setting, emergency department setting, and West region (compared to South and Midwest regions), each of which was associated with lower rates of broad-spectrum prescribing. Age and fever were not associated with prescribing choice. Conclusion Prescribing of broad-spectrum antibiotics for acute otitis media has steadily increased from 1998 to 2004. Associations with non-clinical factors suggest potential for improvement in prescribing practice. PMID:19552819

The present study aimed to assess the prevalence of otitis media and risk-factors for sensorineural hearing loss among infants in the Solomon Islands, in order to recommend an Infant Ear and Hearing Program that would be suitable to the Pacific Island context. Ear examinations and the JCIH Risk-Factor Questionnaire were administered to 288 infants attending Child Welfare Clinics in the Solomon Islands. Overall, 150 infants (52.084%) presented with bilateral normal ear examinations and no risk-factors for SNHL. There were 73 infants (25.34%) with ear pathology in at least one ear, 13 (4.5%) of whom required referral to the ENT Clinic for medical management. The most common pathology was otitis media with effusion (OME) (21.87%). Infants aged 7-12 months were significantly more likely to present with OME (p<0.001) and a history of otitis media (p=0.017) than infants aged 0-6 months. There were 71 infants (24.65%) with at least one risk-factor for sensorineural hearing loss. The most common risk-factors were ototoxicity (8.3%), non-elective caesarean delivery (6.59%), and possible in-utero syphilis infection (5.55%). The prevalence of otitis media and risk-factors for sensorineural hearing loss indicate the importance of initiating Infant Ear and Hearing Programs in the Solomon Islands. Program should facilitate early education on prevention of ear disease, as well as early diagnosis and management of children with hearing loss. Copyright © 2018. Published by Elsevier B.V.

A comparison group (age, sex, insurance product) was utilized to determine if the same-day process decreased facility time and surgical time for the care episode. A parent satisfaction survey was administered. Thirty children, with a median age of 16 months (range, 12-22 months), participated in the same-day surgery process for TT. Twenty-one patients (70.0%) were male, and these patients were matched to a comparison group (similar age, sex, and insurance product) having non-same-day (routine) TT placement. The same-day patients spent significantly less time in clinic for the preoperative physician visit (average, 15 minutes) when compared with the non-same-day patients (average, 51.5 minutes; P < .001). The operative experience for the same-day patients was similar to the non-same-day patients (average, 145 vs 137 minutes, respectively; P = .35), but the overall experience was significantly shorter for the same-day patients (average, 151 vs 196 minutes for comparisons; P < .001). All parents surveyed in the same-day group were satisfied with the efficiency of the experience. The same-day surgery process for management of children who meet the criteria for TT placement is a model of improved efficiency of care for children who suffer from otitis media. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Different virulence of influenza A virus strains and susceptibility to pneumococcal otitis media in chinchillas.

PubMed Central

Giebink, G S; Wright, P F

1983-01-01

We have previously shown that chinchillas infected with a multiply passaged laboratory strain of influenza A/NWS/33 (H1N1) develop negative middle-ear pressure; polymorphonuclear leukocyte oxidative, bactericidal, and chemotactic dysfunction; and increased susceptibility to pneumococcal otitis media. Because influenza A virus strains show different virulence in humans, three such strains were compared in the chinchilla model. Negative middle-ear pressure and tympanic membrane inflammation developed significantly more often in chinchillas infected with wild-type H3N2 virus than with either wild-type H1N1 virus or an attenuated, cold-adapted H3N2 vaccine strain, CR29. Marked depression in polymorphonuclear leukocyte chemiluminescent activity also developed significantly more often in H3N2 infected animals than in H1N1- or CR29-infected animals. Intranasal challenge of influenza virus-infected animals with type 7 Streptococcus pneumoniae resulted in a significantly greater occurrence of pneumococcal otitis media in H3N2-infected animals than in H1N1-, CR29-, or non-influenza-infected control animals. Clearance of pneumococci from nasal washings of animals infected with wild-type H3N2 was significantly delayed in comparison with the other groups. Thus, the previously demonstrated increased susceptibility to otitis media among children infected with H3N2 influenza virus may relate to the capacity of this strain to induce negative middle-ear pressure, polymorphonuclear leukocyte dysfunction, and alteration in the mucosal clearance of pneumococci.

Diagnostic inaccuracy and subject exclusions render placebo and observational studies of acute otitis media inconclusive.

Pichichero, Michael E; Casey, Janet R

2008-11-01

Diagnostic accuracy and appropriate inclusion/exclusion criteria representative of children at greatest risk is of paramount importance in trials to evaluate placebo or observation as an option for acute otitis media (AOM) management. Twelve observational studies spanning the time frame 1958-2005 and 13 natural history studies spanning the time frame 1968-2006 were evaluated for the diagnostic criteria, inclusion criteria, and exclusion criteria applied within the study design. Although a bulging or full tympanic membrane (TM) with effusion is the best indication of a diagnosis of bacterial AOM based on tympanocentesis findings, few observational and natural history studies required a bulging TM. Examination of subject inclusion criteria showed that many subjects did not have AOM but rather had no middle ear disease at all or they had otitis media with effusion. Exclusion criteria of subjects were also remarkable. Frequently children <2 years old were excluded; mean age among the studies reflected an older age group, unlike the true epidemiology of AOM. Otitis prone children, those with severe disease, with a bulging TM, with fever, with a definite need for antibiotics, with recent antibiotic treatment, with recent AOM, or with perforation of the TM were often excluded. Guidelines and some authorities have overlooked or discounted the importance of the issues of inaccurate diagnosis on study entry, broad inclusion criteria, and the creation of bias in exclusion criteria among placebo/natural history trials in AOM. The current data favoring observation of children with AOM should be reconsidered until better studies are conducted.

Limiting the duration of antimicrobial treatment constitutes a potential strategy to reduce the risk of antimicrobial resistance among children with acute otitis media. We assigned 520 children, 6 to 23 months of age, with acute otitis media to receive amoxicillin-clavulanate either for a standard duration of 10 days or for a reduced duration of 5 days followed by placebo for 5 days. We measured rates of clinical response (in a systematic fashion, on the basis of signs and symptomatic response), recurrence, and nasopharyngeal colonization, and we analyzed episode outcomes using a noninferiority approach. Symptom scores ranged from 0 to 14, with higher numbers indicating more severe symptoms. Children who were treated with amoxicillin-clavulanate for 5 days were more likely than those who were treated for 10 days to have clinical failure (77 of 229 children [34%] vs. 39 of 238 [16%]; difference, 17 percentage points [based on unrounded data]; 95% confidence interval, 9 to 25). The mean symptom scores over the period from day 6 to day 14 were 1.61 in the 5-day group and 1.34 in the 10-day group (P=0.07); the mean scores at the day-12-to-14 assessment were 1.89 versus 1.20 (P=0.001). The percentage of children whose symptom scores decreased more than 50% (indicating less severe symptoms) from baseline to the end of treatment was lower in the 5-day group than in the 10-day group (181 of 227 children [80%] vs. 211 of 233 [91%], P=0.003). We found no significant between-group differences in rates of recurrence, adverse events, or nasopharyngeal colonization with penicillin-nonsusceptible pathogens. Clinical-failure rates were greater among children who had been exposed to three or more children for 10 or more hours per week than among those with less exposure (P=0.02) and were also greater among children with infection in both ears than among those with infection in one ear (P<0.001). Among children 6 to 23 months of age with acute otitis media, reduced

Treatment of canine otitis externa with owner-administered products can be difficult. To evaluate otic treatment administered by a veterinarian on quality of life (QoL) of dogs with otitis externa and their owners, and on clinical and cytology parameters of otitis; compared to an owner-administered treatment. Fifty client-owned dogs randomly randomized into two groups and treated for 2 weeks. Veterinarians treated Group A dogs with a veterinary licensed otic gel on two occasions at a 1 week interval; owners treated Group B dogs once daily with a veterinary licensed otic drop based product along with twice weekly cleaning. Veterinarians evaluated otitis with the OTI-3 scale and semi-quantitative cytological examination on days 0, 7, 14 and 28. At each visit, owners assessed QoL with a validated questionnaire and pruritus with a Visual Analog Scale. Scores before and after treatment of each group, and differences between groups were analysed statistically. In both groups, all parameters improved significantly. There was a significantly higher improvement of QoL scores, for dogs and owners, in Group A, compared to Group B at all time points (P < 0.05), except for owner QoL on Day 28. There was no difference in improvement of OTI-3 between groups at any time point, whereas Group A cytology scores and pruritus improved significantly more by Day 7 (P = 0.0026 and P = 0.0294, respectively). A veterinarian-administered otic gel provided equivalent efficacy and higher QoL to dogs with otitis externa and their owners, compared to an owner-administered topical otic therapy. © 2017 The Authors.

2017-06-01

This study introduces a change-oriented short-form health-related quality of life questionnaire suited to symptoms of adult chronic middle ear disease and its consequences, and describes its properties. Two-centre prospective correlational study primarily for instrument development. Two otology secondary care centers in England. Fifty-two consecutive adult patients with active chronic otitis media undergoing surgery. The 12 items for the chronic otitis media benefit inventory (COMBI) were appraised chiefly for internal consistency of resulting score and for factor structure (exploratory factor analysis). The internal consistency of the COMBI was high within our cohort of patients, with a Cronbach's alpha value of 0.907. The three-factor solution from factor analysis explaining 73.6% of the variance was readily interpretable in terms of the intended item content: changes in hearing, ear symptoms, and daily activities plus healthcare uptake. The COMBI has suitable properties for the dynamic assessment of active chronic otitis media. Initial psychometric appraisal confirms its suitability for early adoption to acquire more comprehensive large-sample information with it and on it, for future refinement and application.

To compare outpatient return visits within 2 weeks experienced by pediatric patients diagnosed with otitis media using retail nurse practitioner clinics to similar patients using standard medical office clinics. The impact of retail clinics on return visit rates has not been extensively studied. Electronic medical records of pediatric primary care patients seen in a large group practice in Minnesota in 2009 for otitis media. Patients seen in retail walk-in clinics staffed by nurse practitioners (N = 627) or regular office clinics (N = 2353). A return visit to any site within 2 weeks. The percentage returning was higher in standard care patients than in retail medicine patients (21.0 vs 11.2, P < .001). The odds of a return visit within 2 weeks were higher in standard care patients than in retail medicine patients after adjusting for propensity to use services, age, and gender (odds ratio = 1.54, P < 0.01). In this group practice, the odds of return visits within 2 weeks for pediatric patients treated for otitis media were lower in retail medicine clinics than in standard office clinics.

2018-01-01

The objective of the present study was the determination of the incidence of gastroesophageal reflux disease and the evaluation of its possible influence on the development and duration of chronic exudative otitis media in the children during the first year of life. A total of 141 infants at the age of 3 months presenting with exudative otitis media refractory to the conservative treatment throughout the first 1-1.5 months of life were available for the examination. The effectiveness of the anti-reflux therapy was estimated based on the middle ear condition (the presence or absence of exudate) within 3 and 6 months after the initiation of the treatment. The signs of aspiration of gastric chimus and gastroesophageal reflux disease were documented in 92% of the cases. The anti-reflux treatment during 3 months resulted in the disappearance of the manifestations of exudative otitis media in 43% of the patients. The further prolongation of such therapy up to 6 months allowed to normalize the state of the middle ear in 69% of the children although the remaining 40% failed to respond. It is concluded that the treatment of the children presenting with exudative otitis media during first year of life should be performed taking into consideration the possible involvement of gastroesophageal reflux disease in pathogenesis of this pathological condition.

Within a prospective group study of five practicing otorhinolaryngologists, conventional therapy of acute otitis media in children was compared with homeopathic treatments. Group A (103 children) was primarily treated with homeopathic single remedies (Aconitum napellus, Apis mellifica, Belladonna, Capsicum, Chamomilla, Kalium bichromicum, Lachesis, Lycopodium, Mercurius solubilis, Okoubaka, Pulsatilla, Silicea). Group B (28 children) was treated by decongestant nose-drops, antibiotics, secretolytics and/or antipyretics. Comparisons were done by symptoms, physical findings, duration of therapy and number of relapses. The children of the study were between 1 and 11 years of age. The difference in numbers was explained by the children with otitis media being primarily treated by pediatricians using conventional methods. The median duration of pain in group A was 2 days and in group B 3 days. Median therapy in group A lasted 4 days and in group B 10 days. Antibiotics were given over a period of 8-10 days, while homeopathic treatments were stopped after healing. In group A 70.7% of the patients were free of relapses within 1 years and 29.3% had a maximum of three relapses. Group B had 56.5% without relapses and 43.5% a maximum of six relapses. Five children in group A were given antibiotics and 98 responded solely to homeopathic treatments. No side effects of treatment were found in either group.

Comparison of study designs for acute otitis media trials.

Pichichero, Michael E; Casey, Janet R

2008-06-01

A framework for evaluating the efficacy of antibiotics in development as well as those currently approved for acute otitis media (AOM) is needed. Review strengths and limitations of various antibiotic trial designs and their outcome measures. A review of 157 published trials involving 36,710 subjects for the treatment of AOM. AOM trials have three designs: (1) clinical, clinical diagnosis and assessment of outcomes; (2) single tympanocentesis, microbiologic diagnosis (by middle ear fluid culture) and clinical assessment of outcomes; and (3) double tympanocentesis, microbiologic diagnosis and microbiologic outcome assessment. Identifiable strengths and limitations of each design are reviewed. Case definitions for entry of children in trials of AOM vary widely. The lack of stringent diagnostic criteria in a clinical design allows for inclusion of a significant proportion of children with a non-bacterial etiology (i.e., viral AOM or otitis media with effusion). Tympanocentesis increases diagnostic accuracy at study entry; however, the procedure is confounding because of its potentially therapeutic benefit and the procedure is not performed in a uniform manner. A second tympanocentesis allows a high sensitivity to detect microbiologic eradication, but it does not correlate with clinical outcomes in half of the cases. The timing of outcome assessment also varies widely among trials. Improved clinical diagnosis criteria for AOM are needed to enhance specificity; emphasis on a bulging tympanic membrane has the best evidence base. Tympanocentesis within study designs has merits. At study entry it assures diagnostic accuracy but may alter outcomes and it is useful to document microbiologic outcomes but lacks specificity for clinical outcomes. For all designs, test of cure assessment 2-7 days after completion of therapy seems most appropriate.

Mucosal pathology of an experimental otitis media with effusion after X-ray irradiation

Ten guinea pigs were irradiated with 30 Gy of x-radiation. Five were killed on the eighth day after irradiation, and the remainder were killed at the sixteenth day after irradiation. At the time of death, examination was made of the ciliary activity and the fine structure of the middle ear mucosa. Serous effusion was found in each tympanic cavity of all animals. It was shown also that the guinea pig, when irradiated with 30 Gy of x-radiation, exhibits pathologic abnormalities similar to those in humans with otitis media with effusion: degeneration of cilia or ciliated cells and changes in themore » vascular system (capillary injury and increased capillary permeability). Functional examinations showed that x-ray irradiation has delayed effects on ciliary activity, and the effects are much greater at the sixteenth day than at the eighth day. We speculate that the accumulation of effusion can be, at least partially, a consequence of ciliary dysfunction. The induction of sterile effusion by the use of x-ray irradiation provides a unique animal model for chronic otitis media with effusion of the serous type.« less

Background: Chronic otitis media with effusion is a persistent complication essentially universal in children with cleft palate. The prevalence of chronic otitis media with effusion is hypothesized to be a result of Eustachian tube dysfunction secondary to the anomalous insertion of the palatal musculature. This study was designed to evaluate the timing of tympanostomy tube placement and the effect of primary palatoplasty technique on the recovery of Eustachian tube function and resolution of chronic otitis media with effusion. Methods: We performed a retrospective, cross-sectional analysis of the previous 99 consecutive patients who underwent a palatoplasty at our institution. Variables included timing of initial tympanostomy tube placement, palatoplasty technique, cleft type, and gender. These were then evaluated to assess their impact on the resolution of chronic otitis media with effusion. Resolution was established as an inverse function of the number of tympanostomy tubes placed in correlation with available audiometric/tympanographic data. For all models, a generalized linear mixed model was applied using a Poisson distribution and a log-link function where the outcome variable was the total number of tympanostomy tubes. For all tests, a P = .05 level of significance was used. Results: Of 99 palatoplasties performed, 94 patients were included in the study. Ninety-one percent of patients had documented chronic otitis media with effusion at the time of palatoplasty. Forty-four percent underwent straight-line repair with aggressive intravelar veloplasty, 36% had Furlow double z-plasty, 20% had straight-line repair without intravelar veloplasty. There was a statistically significant difference (F2,83 = 5.36, P = .0065) between the 3 types of repair. The mean number of tubes placed was 0.6000 ± 0.1225, 0.8519 ± 0.1776, and 1.4737 ± 0.2785 for intravelar veloplasty, Furlow double z-plasty, and straight line without intravelar veloplasty, respectively .

Health care systems and physicians need to conform to budgets and streamline resources to provide cost-effective quality care. Although endoscopic tympanoplasty (ET) has been performed for decades, no studies on the cost-effectiveness of ET and microscopic tympanoplasty (MT) for treating chronic otitis media have been published. The present study aimed to compare the cost-effectiveness of ET and MT for treating chronic otitis media. This study was performed using a Cohort-style Markov decision-tree economic model with a 30-year time horizon. The economic perspective was that of a third-party payer (Taiwan National Health Insurance System). Two treatment strategies were compared, namely ET and MT. The primary outcome was the incremental cost per quality-adjusted life year (QALY). Probabilities were obtained from meta-analyses. Costs were obtained from the published literature and Taiwan National Health Insurance System database. Multiple sensitivity analyses were performed to account for data uncertainty. The reference case revealed that the total cost of ET was $NT 20,901 for 17.08 QALY per patient. By contrast, the total cost of MT was $NT 21,171 for 17.15 QALY per patient. The incremental cost effectiveness ratio for ET versus that of MT was $NT 3703 per QALY. The cost-effectiveness acceptability curve indicated that ET was comparable to MT at a willingness-to-pay threshold of larger than $NT 35,000 per QALY. This cost-effectiveness analysis indicates that ET is comparable to MT for treating chronic otitis media in Taiwan. This result provides the latest information for physicians, the government, and third-party payers to select proper clinical practice. Copyright © 2017. Published by Elsevier Taiwan LLC.

Primary secretory otitis media in Cavalier King Charles spaniels.

Primary secretory otitis media (PSOM) is a disease that has been described in the Cavalier King Charles spaniel (CKCS). A large, bulging pars flaccida identified on otoscopic examination confirms the diagnosis. However, in many CKCS with PSOM the pars flaccida is flat, and radiographic imaging is needed to confirm the diagnosis. Current treatment for PSOM includes performing a myringotomy into the caudal-ventral quadrant of the pars tensa with subsequent flushing of the mucus out of the bulla using a video otoscope. Repeat myringotomies and flushing of the middle ear are necessary to keep the middle ear free of mucus. Copyright © 2012 Elsevier Inc. All rights reserved.

Should homeopathy be considered as part of a treatment strategy for otitis media with effusion in children?

PubMed

Fixsen, Alison

2013-04-01

Otitis media with effusion (OME) or 'glue ear' is the most common cause of pediatric hearing loss, and a drain on global healthcare resources. It is associated with frequent episodes of acute otitis media (AOM) and upper respiratory tract infections (URTIs) and linked with environmental and social factors, including diet, smoking households, overcrowding and day care use. Current conventional treatment for OME is unsatisfactory, the area constitutes an 'effectiveness gap'. Homeopathy is a relatively common and popular choice of complementary and alternative medicine (CAM) treatment for childhood conditions, including otitis media. Antibiotic resistance is now a major global problem, homeopathy may have a role to play in combating its further development. Systematic review of the literature for clinical studies of homeopathy for AOM and upper respiratory tract disorders. Discussion in the context of current treatment options and public health issues including antibiotic resistance. Several randomized trials and outcome studies of homeopathy for AOM and upper respiratory tract disorders have been published. The results are encouraging, but the volume of research is small and insufficient to draw definitive conclusions. A strategy based on multi-centre or multiple, linked clinical trials of homeopathy for OME, using a pragmatic framework and evaluating long-term effects in different settings, in conjunction with other healthcare and social services should be considered. Reduction of antibiotic use is an important outcome. Copyright © 2013 The Faculty of Homeopathy. Published by Elsevier Ltd. All rights reserved.

This study was undertaken to revise the diagnostic characteristics of tuberculous otitis media (TOM), a disorder that is often diagnosed late, leading to delay in specific treatment. Retrospective study of a longitudinal series of 10 TOM patients over a 7-year period at an institutional referral center. Most patients showed intractable otorrhea, moderately severe hearing loss, and necrotic eardrums with granulation tissue and single perforations. Multiple perforations, facial palsy, and cervical adenopathies were rare (<10% of patients). CT generally showed soft tissue involvement of the middle ear without bone erosion. The most effective laboratory test microbiological culture of exudate (diagnostic efficacy 71%). Specific antibiotic treatment was effective in all cases. The diagnosis of TOM remains a significant challenge for otorhinolaryngologists. If there are strong clinical grounds for suspicion, standard laboratory tests for tuberculosis should be repeated even if initially negative.

Otitis media with effusion (OME) is characterised by an accumulation of fluid in the middle ear behind an intact tympanic membrane, without the symptoms or signs of acute infection. Since most cases of OME will resolve spontaneously, only children with persistent middle ear effusion and associated hearing loss potentially require treatment. Previous Cochrane reviews have focused on the effectiveness of ventilation tube insertion, adenoidectomy, nasal autoinflation, antihistamines, decongestants and corticosteroids in OME. This review, focusing on the effectiveness of antibiotics in children with OME, is an update of a Cochrane review published in 2012. To assess the benefits and harms of oral antibiotics in children up to 18 years with OME. The Cochrane ENT Information Specialist searched the ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2016, Issue 3); PubMed; Ovid EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 April 2016. Randomised controlled trials comparing oral antibiotics with placebo, no treatment or therapy of unproven effectiveness in children with OME. We used the standard methodological procedures expected by Cochrane. Twenty-five trials (3663 children) were eligible for inclusion. Two trials did not report on any of the outcomes of interest, leaving 23 trials (3258 children) covering a range of antibiotics, participants, outcome measures and time points for evaluation. Overall, we assessed most studies as being at low to moderate risk of bias.We found moderate quality evidence (six trials including 484 children) that children treated with oral antibiotics are more likely to have complete resolution at two to three months post-randomisation (primary outcome) than those allocated to the control treatment (risk ratio (RR) 2.00, 95% confidence interval (CI) 1.58 to 2.53; number needed to treat to benefit (NNTB) 5).

Background Recommendations vary regarding immediate antimicrobial treatment versus watchful waiting for children younger than 2 years of age with acute otitis media. Methods We randomly assigned 291 children 6 to 23 months of age, with acute otitis media diagnosed with the use of stringent criteria, to receive amoxicillin–clavulanate or placebo for 10 days. We measured symptomatic response and rates of clinical failure. Results Among the children who received amoxicillin–clavulanate, 35% had initial resolution of symptoms by day 2, 61% by day 4, and 80% by day 7; among children who received placebo, 28% had initial resolution of symptoms by day 2, 54% by day 4, and 74% by day 7 (P = 0.14 for the overall comparison). For sustained resolution of symptoms, the corresponding values were 20%, 41%, and 67% with amoxicillin–clavulanate, as compared with 14%, 36%, and 53% with placebo (P = 0.04 for the overall comparison). Mean symptom scores over the first 7 days were lower for the children treated with amoxicillin–clavulanate than for those who received placebo (P = 0.02). The rate of clinical failure — defined as the persistence of signs of acute infection on otoscopic examination — was also lower among the children treated with amoxicillin–clavulanate than among those who received placebo: 4% versus 23% at or before the visit on day 4 or 5 (P<0.001) and 16% versus 51% at or before the visit on day 10 to 12 (P<0.001). Mastoiditis developed in one child who received placebo. Diarrhea and diaper-area dermatitis were more common among children who received amoxicillin–clavulanate. There were no significant changes in either group in the rates of nasopharyngeal colonization with nonsusceptible Streptococcus pneumoniae. Conclusions Among children 6 to 23 months of age with acute otitis media, treatment with amoxicillin–clavulanate for 10 days tended to reduce the time to resolution of symptoms and reduced the overall symptom burden and the rate of

[Detection of split products of the immunoglobulins IgG, IgA and IgM during chronic otitis media (author's transl)].

Proteolytic enzymes such as pepsine or papaine are able to split IgG antibodies into large fragments in vitro. These immunoglobulin fragments (IgG, IgA, IgM) were now detected in vivo from the purulent secretions of cholesteatoma, chronic otitis media and radical mastoid cavities. During chronic otitis media the intact immunoglobulins are split due to the proteolytic activity of neutral proteinases. These fragments were qualitatively and quantitatively investigated by means of various immunological procedures. After the immunoelectrophoretic separation of the purulent middle-ear-secretions and after diffusion against anti-IgG-, anti-IgA- and anti-IgM- serum double precipitate lines could be observed especially in middle-ear-secretion with a bacterial flora of pseudomonas aeruginosa (pyocyanea) and of the proteus-providencia-group. This was the first proof of the presence of split products of the immunoglobulins. The exact demonstration of these split products could be carried out by gel-filtration and fractionation of the intact and split immunoglobulins. During chronic otitis media intact immunoglobulins are split by leucocytic and extracellular bacterial proteinases into fragments of different molecular weight. The most malignant extracellular proteinases with the greatest proteolytic activity against intact immunoglobulins are the bacterial proteinases of pseudomonas aeruginosa. These proteinases can not be inhibited by the other serum proteinaseinhibitors except for alpha-2-macroglobulin of the human blood serum. This inhibitor has a very high molecular weight so that we can not find it in a higher concentration in the middle-ear-secretion. We can liberate this inhibitor by injuring the blood vessels during a tympanoplasty. In this way we get an inhibitory effect against these proteinases and combined with an appropriate antibiotic therapy we can cure a chronic otitis media.

Barotrauma vis-a-vis the "chronic otitis media syndrome": two conditions with middle ear gas deficiency Is secretory otitis media a contraindication to air travel?

PubMed

2003-03-01

We compared 17 patients (29 ears) with barotrauma with 171 patients suffering from "chronic ears" (secretory otitis media, atelectasis, or previously operated cholesteatoma). The patients with "chronic ears" were followed up prospectively, and none were found to suffer from barotrauma after flying on a commercial airplane. The mastoid pneumatization (seen on lateral mastoid radiographs) was significantly larger in ears with barotrauma, averaging 16.85 cm2, versus 12.9 cm2 in normal controls, whereas in "chronic ears" it was only 3.6 cm2. During flight on a commercial airplane, the middle ear has to equalize about 20% of its gas volume with the ambient pressure. This equalization must happen within 15 to 20 minutes of ascent and descent in order to avoid barotrauma. This 20% is a fivefold greater task for ears with a large mastoid pneumatization than for ears with an undeveloped pneumatization; "chronic ears" usually have an undeveloped mastoid pneumatization. The smaller the middle ear (mastoid) volume, the smaller the volume of gas needed to pass through the eustachian tube in order to equalize pressure changes during flying. This factor may explain why "chronic ears" rarely suffer from barotrauma. It also implies that eustachian tubes of secretory otitis, atelectatic, and cholesteatomatous ears have little problem in equalizing large pressure differences (over 2,000 mm H2O) within 15 to 20 minutes of landing, in contrast to what has been traditionally believed. Individuals with "chronic ears" can be advised that they can fly safely.

The positive effects of spa therapy on ear, nose, and throat pathology are known but robust literature in this field, is still lacking. The aim of this study was to assess through a retrospective analysis, the effects on otitis media with effusion of Politzer endotympanic inhalation of sulphurous waters in children aged 5-9 years. A cohort of 95 patients was treated with Politzer insufflations of sulphurous water: 58 patients did a cycle consisting of a treatment of 12 days per year for three consecutive years; 37 patients followed the same procedure for 5 years consecutively. The control population was represented by untreated, age-matched children. A standard audiometric test was used before and after each cycle of treatment. One cycle of Politzer inhalation of sulphur-rich water improved the symptoms. Three cycles definitively stabilized the improvement of hearing function. Our results show that otitis media with effusion in children can be resolved by an appropriate non-pharmacological treatment of middle ear with sulphur-rich water.

This retrospective study reports on the clinical and radiologic features and the treatment outcomes of patients with tuberculous otitis media (TOM). We reviewed the medical records of 52 patients (53 ears) with TOM between 1993 and 2005 and analyzed temporal bone computed tomography scans of 23 patients. The diagnosis of TOM was made if a specimen of the middle ear revealed the presence of acid fast bacilli (AFB), grew Mycobacterium tuberculosis (M. Tb) on a culture, revealed characteristic histology, and/or was positive for polymerase chain reaction (PCR) for M. Tb. The highest incidence of the disease was observed among patients in their 30s. The main symptom was otorrhea, and the duration of symptoms was shorter than with nonspecific chronic otitis media. Most patients demonstrated a moderate to severe hearing loss. Five patients (9.6%) demonstrated a peripheral-type facial palsy. Temporal bone CT scans demonstrated relatively well-pneumatized mastoids and occupation by soft tissue of the entire tympanum and mastoid air cells. Six patients demonstrated bone destruction that involved the cortex of the mastoid bone. In most patients, antituberculous medication was effective treatment. The patients who underwent chemotherapy after surgery achieved more rapid healing of the ear and more frequent closure of the tympanic membrane than those who did not receive surgery. Clinicians should have a high index of suspicion and be aware of the clinical and radiologic characteristics of TOM.

The volume of the mucous paratubal glands and the number of the mucus-producing goblet cells in the middle ear and Eustachian tube (ET) are increased after experimental acute otitis media (AOM). The present investigation examines a potential effect of penicillin on the changes in goblet cell density and gland structures of the ET during and after AOM. Middle ear inoculation of Streptococcus pneumoniae in 50 rats. Two days later, 25 rats were given penicillin V as one daily dose for 5 days. Twenty-five rats received no treatment. Five animals from each group were sacrificed on days 4, 8, 16, 90, and 180. The ET was dissected and decalcified, followed by paraffin embedding, serial transverse sectioning, and PAS/alcian blue staining. The goblet cell density and the paratubal gland composition and volume were determined in every 20th section, using a light microscope. Penicillin reduced the increase of goblet cell density from day 8 and through 6 months, whereas the increase of the paratubal mucous gland volume was unaffected by treatment. We conclude that penicillin reduces the increase of ET goblet cell density during and after acute otitis media, whereas the paratubal gland volume remains unaffected. An increased mucosal secretory capacity and indicated excessive secretion of mucus may contribute to the deteriorated ET function found after AOM and thus predispose, sustain, or aggravate middle ear disease. This may be prevented by penicillin treatment.

Malassezia pachydermatis can cause infections of the skin and mucous membranes, especially in animals. It becomes a problem also in medicine. It is considered that metabolic disorders as well as hormonal and immunological status of the host promote diseases caused by M. pachydermatis. Here we consider whether specific features of fungi could also favour infections. We checked whether there are differences in lipid profiles between strains obtained from dogs with otitis externa and strains obtained from healthy dogs. Lipid profiles were determined using thin layer chromatography and gas chromatography-mass spectrometry. All analyses were carried out on 32 strains derived from dogs with otitis externa and 31 strains isolated from dogs without symptoms of disease. The results show that strains isolated from dogs without symptoms of otitis externa are characterised by a higher content of fatty acids. They contain significantly more behenic and lignoceric acids on medium without addition of lipids, and more oleic acid and total monounsaturated fatty acids on medium with lipids supplementation. These strains have also a higher content of esters of ergosterol and triglycerides. Data obtained show differences which may be specific features of M. pachydermatis-specific strains related to the ability of infection, which could be not directly related of the host condition. © 2015 Blackwell Verlag GmbH.

Otitis media (OM) with mucoid effusion, characterized by mucous cell metaplasia/hyperplasia in the middle ear cleft and thick fluid accumulation in the middle ear cavity, is a subtype of OM which frequently leads to chronic OM in young children. Multiple factors are involved in the developmental process of OM with mucoid effusion, especially disorders of mucin production resulting from middle ear bacterial infection and Eustachian tube dysfunction. In this review, we will focus on several aspects of this disorder by analyzing the cellular and molecular events such as mucin production and mucous cell differentiation in the middle ear mucosa with OM. In addition, infectious agents, mucin production triggers, and relevant signaling pathways will be discussed. PMID:22685463

We fix the level of language skills among 16 children between 5 and 6 year-old, being affected from long lasting CSO. The incidence of alterations was 20 percent in the under of 5, that increases till 33 percent in the sub-group of 6 year-old. These numbers are interesting enough in order to insist in the need of requiringan effective and early treatment of CSO patients and also of scholar implication in its global handling.

We presented the first case report of Pseudoclavibacter otitis media in a boy with pulmonary and spinal tuberculosis.A 3-year-old boy was referred to our hospital due to prolonged fever and progressive paraplegia for 3 months. He had yellowish discharge from both ear canals. The pleural fluid culture was positive for Mycobacterium tuberculosis. The discharge from both ears culture yielded yellow colonies of gram-positive bacilli with branching. This organism was positive for modified acid-fast bacilli stain but negative for acid-fast bacilli stain. Biochemical characteristics of this isolate were positive for catalase test but negative for oxidase, nitrate, esculin, and sugar utilization tests. The organism was further subjected to be identified by 16S ribosomal deoxyribonucleic acid gene sequencing. The result yielded Pseudoclavibacter species (99.4% identical), which could be most likely a potential pathogen in immunocompromised host like this patient. He responded well with intravenous trimetroprim-sulfamethoxazole for 6 weeks.This is the first case report of Pseudoclavibacter otitis media in children, and this case could emphasize Pseudoclavibacter species as a potential pathogen in immunocompromised host.

Tuberculosis, a contagious bacterial disease which is caused by Mycobacterium tuberculosis, primarily involves the lungs.Though Pulmonary tuberculosis (PTB) is the commonest clinical presentation, there is a need for alertness towards uncommon presentations which involve other organs. Tuberculous otitis media (TOM) is one such rare presentation seen in paediatric practice. It is characterized by painless otorrhoea which fails to respond to the routine antibacterial treatment. TOM usually occurs secondary to PTB. Here is a case of tuberculous otitis media with Proteus mirabilis co-infection, with no evidence of PTB. In the sample of ear discharge obtained from the patient, acid fast bacilli were demonstrated on direct microscopy after Ziehl-Neelsen staining. Culture done on Lowenstein-Jensen medium demonstrated slow-growing Mycobacterium. Bacteriological culture and identification helped in isolating Proteus mirabilis. PCR, followed by Line- Probe Assay for early identification and susceptibility testing to primary drugs, was done. Further, patient tested negative for the Mantoux test. Patient was enrolled in National Tuberculosis programme- RNTCP. This case emphasizes on one of the less common presentations of a common disease. A high clinical suspicion and laboratory confirmation are required for appropriate patient management.

Computed tomography (CT) of the temporal bone was made in 37 patients aged 2 to 55 years with chronic exudative otitis media (CEOM). In 21 of them the pathology was bilateral. The analysis of 58 CT images has identified CT signs of chronic exudative otitis media. They include partial (17 temporary bones) or complete (38 temporal bones) block of the bone opening of the auditory tube, pneumatic defects of the tympanic cavity (58 temporal bones), pneumatic defects of the mastoid process and antrum (47 temporal bones), pathologic retraction of the tympanic membrane. The examination of the temporal bone detected both CT-signs of CEOM and other causes of hearing disorders in 14 patients (26 temporal bones) with CEOM symptoms and inadequately high hypoacusis. Among these causes were malformation of the auditory ossicula (n=5), malformation of the labynthine window (n=2), malformation of the middle and internal ear (n=4), a wide aqueduct of the vestibule, labyrinthine anomaly of Mondini's type (n=1), cochlear hypoplasia (n=4), stenosis of the internal acoustic meatuses (n=2). Sclerotic fibrous dysplasia was suggested in 2 temporal bones (by CT data). CT was repeated after surgical treatment of 10 patients (14 temporal bones) and visual assessment of tympanostomy results was made.

Non-typeable (NT) or capsule-deficient, Haemophilus influenzae (Hi) is a common commensal of the upper respiratory tract of humans and can be pathogenic resulting in diseases such as otitis media, sinusitis and pneumonia. The lipopolysaccharide (LPS) of NTHi is a major virulence factor that displays substantial intra-strain and inter-strain variation of its oligosaccharide structures. To investigate the genetic basis of LPS variation we sequenced internal regions of each of seven genes required for the biosynthesis of either the inner or the outer core oligosaccharide structures. These sequences were obtained from 25 representative NTHi isolates from episodes of otitis media. We found abundant evidence of recombination among LPS genes of NTHi, a finding in marked contrast to previous analyses of biosynthetic genes for capsular polysaccharide, a well-documented virulence factor of Hi. We found mosaic sequences, linkage equilibrium between loci and a lack of congruence between gene trees. These high rates were not confined to LPS genes since evidence for similar amounts of recombination was also found in eight housekeeping genes in a subset of the same 25 isolates. These findings provide a population based foundation for a better understanding of the role of NTHi LPS as a virulence factor and its potential as a candidate vaccine. PMID:12797973

In hypertrophied adenoid lymphocytes B make up about 60% all lymphocytes. When the lymphocytes B come in interaction with antigens this membranes signal be passed through their receptor (BCR) to interior of cell. This signal affect modulation on gene expression, activation from which depends activation, anergy or apoptosis of lymphocyte B. Accompany BCR co-receptors regulate his functions influence stimulate or inhibitive. To the most important co-receptors stepping out on lymphocyte B belong: CD40, CD22, CD72. The aim of study was evaluation of lymphocytes B (CD19) with co-expression with CD72 and CD40 receptors in hypertrophied adenoid with at children with otitis media with effusion. An investigation was executed in hypertrophied adenoids with or without otitis media with effusion. By flow cytometry percentage of lymphocytes B with co-receptors CD 40, CD22 and CD72 in was analyzed. The percentages of CD19+CD72+ lymphocytes in the group of children with adenoid hypertrophy and exudative otitis media were lower as compared to the reference group. However, the percentages of CD19+CD22+, CD19+CD40+ in the study group was approximate to the reference group. The lower percentage of lymphocytes B CD72 + near approximate percentages of lymphocytes B CD40+ and BCD22+ at children with otitis media with effusion can be the cause of incorrect humoral response in hypertrophied adenoid at children. Maybe it is cause reduced spontaneous production IgA and IgG through lymphocyte at children with otitis media with effusion.

The objective of the present work was to estimate the effectiveness and safety of combined anti-inflammatory therapy of exudative otitis media with the use of fenspiride (erespal). The study included 75 patients of whom 35 (group 1) were given standard therapy supplemented by erespal (80 mg thrice daily); the remaining patients receiving standard therapy alone formed group 2 (control). The patients treated with erespal reported the subjective improvement of hearing and reduced congestion on days 7 - 8. Similar changes in group 2 occurred on day 10. It is concluded that the use of erespal for the combined treatment of the patients presenting with exudative otitis media reduces the duration of hospital stay, accelerates recovery, and promotes rapid normalization of hearing.

Authorities have suggested restriction of azithromycin use as a principal strategy to contain the spread of azithromycin-nonsusceptible Streptococcus pneumoniae (ANSP). In 83 children persistently colonized by pneumococcus during and after treatment of acute otitis media, 17 acquired a new strain, 9 of which were less susceptible to azithromycin than the original isolate. New appearance of ANSP was documented after both beta-lactam and azithromycin exposure. ANSP is likely to disseminate even with significant reduction of azithromycin use unless other antibiotic use is decreased as well.

Treatment options in otitis media with effusion.

Secretary Otitis media with effusion (OME) is the accumulation of mucus in the middle ear and sometimes in the mastoid air cell system. The main etiological factor is alteration in mucociliary system of middle ear secondary to ET malfunction which may be primary or secondary. OME is the cause of concern due to its occurance in paediatric age group, highest at 2 years of age, presenting as impairment of hearing leading to delayed speech and language development, poor academic performance and behavioral problems. In spite of this there are no confirmed guidelines of treatment to overcome. Many treatment options are available medical as well as surgical. Prospective study conducted to evaluate various treatment options revealed that auto inflation of ET is the main stay of treatment. If the ET malfunction is due to any reasons like adenoids, deviated nasal septum, hypertrophied turbinates or any other cause surgical intervention of the same gives 100% results. Medical management gives good results but recurrence is equally common.

Cochlear pathology in chronic suppurative otitis media.

PubMed

Walby, A P; Barrera, A; Schuknecht, H F

1983-01-01

Chronic suppurative otitis media (COM) is reported to cause elevation of bone-conduction thresholds either by damage to cochlear sensorineural structures or by alteration in the mechanics of sound transmission in the ear. A retrospective study was made of the medical records of 87 patients with unilateral uncomplicated COM to document that abnormality in bone conduction does exist. In a separate study the cochlear pathology in 12 pairs of temporal bones with unilateral COM was studied by light microscopy. Infected ears showed higher than normal mean bone-conduction thresholds by amounts ranging from 1 dB at 500 Hz to 9.5 dB at 4,000 Hz. The temporal bones showed no greater loss of specialized sensorineural structures in infected ears than in normal control ears. Because there is no evidence that COM caused destruction of hair cells or cochlear neurons, alteration in the mechanics of sound transmission becomes a more plausible explanation for the hearing losses.

The Epidemiology of otitis media with spontaneous perforation of the tympanic membrane and associated nasopharyngeal carriage of bacterial otopathogens was analysed in a county in Catalonia (Spain) with pneumococcal conjugate vaccines (PCVs) not included in the immunization programme at study time. A prospective, multicentre study was performed in 10 primary care centres and 2 hospitals (June 2011-June 2014), including all otherwise healthy children ≥2 months ≤8 years with otitis media presenting spontaneous tympanic perforation within 48h. Up to 521 otitis episodes in 487 children were included, showing by culture/PCR in middle ear fluid (MEF): Haemophilus influenzae [24.2%], both Streptococcus pneumoniae and H. influenzae [24.0%], S. pneumoniae [15.9%], Streptococcus pyogenes [13.6%], and Staphylococcus aureus [6.7%]. Culture-negative/PCR-positive otitis accounted for 31.3% (S. pneumoniae), 30.2% (H. influenzae) and 89.6% (mixed S. pneumoniae/H. influenzae infections). Overall, incidence decreased over the 3-year study period, with significant decreases in otitis by S. pneumoniae and by H. influenzae, but no decreases for mixed S. pneumoniae/H. influenzae infections. Concordance between species in nasopharynx and MEF was found in 58.3% of cases, with maximal rates for S. pyogenes (71.8%), and with identical pneumococcal serotype in 40.5% of cases. Most patients (66.6%) had past episodes. PCV13 serotypes were significantly more frequent in first episodes, in otitis by S. pneumoniae as single agent, and among MEF than nasopharyngeal isolates. All non-PCV13 serotypes separately accounted for <5% in MEF. Up to 73.9% children had received ≥1 dose of PCV, with lower carriage of PCV13 serotypes than among non-vaccinated children. Pooling pneumococcal isolates from MEF and nasopharynx, 30% were multidrug resistant, primarily belonging to serotypes 19A [29.8%], 24A [14.3%], 19F [8.3%] and 15A [6.0%].

The Epidemiology of otitis media with spontaneous perforation of the tympanic membrane and associated nasopharyngeal carriage of bacterial otopathogens was analysed in a county in Catalonia (Spain) with pneumococcal conjugate vaccines (PCVs) not included in the immunization programme at study time. A prospective, multicentre study was performed in 10 primary care centres and 2 hospitals (June 2011-June 2014), including all otherwise healthy children ≥2 months ≤8 years with otitis media presenting spontaneous tympanic perforation within 48h. Up to 521 otitis episodes in 487 children were included, showing by culture/PCR in middle ear fluid (MEF): Haemophilus influenzae [24.2%], both Streptococcus pneumoniae and H. influenzae [24.0%], S. pneumoniae [15.9%], Streptococcus pyogenes [13.6%], and Staphylococcus aureus [6.7%]. Culture-negative/PCR-positive otitis accounted for 31.3% (S. pneumoniae), 30.2% (H. influenzae) and 89.6% (mixed S. pneumoniae/H. influenzae infections). Overall, incidence decreased over the 3-year study period, with significant decreases in otitis by S. pneumoniae and by H. influenzae, but no decreases for mixed S. pneumoniae/H. influenzae infections.

Otitis media (OM) is amongst the most common childhood diseases and is associated with multiple microbial pathogens within the middle ear. Global and temporal monitoring of predominant bacterial pathogens is important to inform new treatment strategies, vaccine development and to monitor the impact of vaccine implementation to improve progress toward global OM prevention. A systematic review of published reports of microbiology of acute otitis media (AOM) and otitis media with effusion (OME) from January, 1970 to August 2014, was performed using PubMed databases. This review confirmed that Streptococcus pneumoniae and Haemophilus influenzae, remain the predominant bacterial pathogens, with S. pneumoniae the predominant bacterium in the majority reports from AOM patients. In contrast, H. influenzae was the predominant bacterium for patients experiencing chronic OME, recurrent AOM and AOM with treatment failure. This result was consistent, even where improved detection sensitivity from the use of polymerase chain reaction (PCR) rather than bacterial culture was conducted. On average, PCR analyses increased the frequency of detection of S. pneumoniae and H. influenzae 3.2 fold compared to culture, whilst Moraxella catarrhalis was 4.5 times more frequently identified by PCR. Molecular methods can also improve monitoring of regional changes in the serotypes and identification frequency of S. pneumoniae and H. influenzae over time or after vaccine implementation, such as after introduction of the 7-valent pneumococcal conjugate vaccine. Globally, S. pneumoniae and H. influenzae remain the predominant otopathogens associated with OM as identified through bacterial culture; however, molecular methods continue to improve the frequency and accuracy of detection of individual serotypes. Ongoing monitoring with appropriate detection methods for OM pathogens can support development of improved vaccines to provide protection from the complex combination of otopathogens within

The clinical features of tuberculous otitis media (TOM) have changed. This study was performed to evaluate changing trends in the clinical manifestations of TOM. We reviewed a series of 12 cases of TOM (13 ears) recently treated at Osaka Prefectural Habikino Hospital. The results showed a mean age of 41 years and a male predominance of 1.4 to 1. Central or total perforations of the tympanic membrane were observed in most cases, but none of the patients had multiple perforations. Nine patients (75%) had active pulmonary tuberculosis. Normal lung status or inactive pulmonary tuberculosis was significantly more frequent in the older age group. Diagnosis of primary TOM required more time than that of secondary TOM. Most cases of primary TOM had high infectiousness of the primary lesion. We summarize the clinical features of patients who should be evaluated for TOM.

Objectives The positive effects of spa therapy on ear, nose, and throat pathology are known but robust literature in this field, is still lacking. The aim of this study was to assess through a retrospective analysis, the effects on otitis media with effusion of Politzer endotympanic inhalation of sulphurous waters in children aged 5-9 years. Methods A cohort of 95 patients was treated with Politzer insufflations of sulphurous water: 58 patients did a cycle consisting of a treatment of 12 days per year for three consecutive years; 37 patients followed the same procedure for 5 years consecutively. The control population was represented by untreated, age-matched children. A standard audiometric test was used before and after each cycle of treatment. Results One cycle of Politzer inhalation of sulphur-rich water improved the symptoms. Three cycles definitively stabilized the improvement of hearing function. Conclusion Our results show that otitis media with effusion in children can be resolved by an appropriate non-pharmacological treatment of middle ear with sulphur-rich water. PMID:23524467

To determine whether oxidative metabolic products of phagocytic cells are present in the middle ear during experimental pneumococcal otitis media, we measured the concentration of myeloperoxidase (MPO) in middle ear fluid (MEF) and the capacity of neutrophils isolated from MEF and peripheral blood to produce MPO and superoxide anion (O2-) after in vitro stimulation. Free MPO in MEF was significantly increased 24 and 48 h after either viable or nonviable pneumococci were inoculated into the middle ear. In vitro-stimulated production of MPO and O2- from middle ear neutrophils was significantly less than that from peripheral blood neutrophils 24 h after nonviable pneumococci were inoculated but similar to it after 48 h. Twenty-four hours after viable pneumococci were inoculated, middle ear neutrophils stimulated in vitro produced less MPO but the same amount of O2- as did blood neutrophils. Oxidative metabolic products, therefore, are released from phagocytic cells into the MEF during pneumococcal otitis media, and future studies will need to define the contribution of these products to acute and chronic middle ear tissue injury.

Otitis media (OM) has been observed at elevated prevalence rates in Greenlandic children. OM associated hearing loss (HL) may compromise the children's linguistic skills, social development and educational achievements. We investigated the prevalence of chronic suppurative otitis media (CSOM), otitis media with effusion (OME) and tympanic membrane sequelae of OM, and compared the corresponding hearing thresholds. In 2010 we examined a cohort of 223 Greenlandic children aged 4-10 years by video otoscopy, tympanometry and tested hearing thresholds for the low-frequencies: 500, 1000 and 2000Hz and the high-frequencies: 4000 and 6000Hz. HL was categorized according to the worst hearing ear and was compared within the groups: CSOM, OME, tympanic membrane sequelae of OM and normal. Of 207 children, 5.8% had CSOM, 13.9% had OME and 55.6% had tympanic membrane sequelae of OM. The median pure tone average in low-frequencies/high-frequencies were: CSOM: 34.2/31.3dB, OME: 23.3/22.5dB, Sequelae of OM: 13.3/15dB and normal ears: 11.7/12.5dB. We found a significant difference (p<0.05) between the four groups. In 56.5% of all children a HL>15dB in any frequency was found, while 6.5% suffered from a bilateral low-frequency HL>25dB. The severity of OM significantly corresponded to increased HL. The burden of CSOM and HL remains high in young Greenlandic children. Aggressive treatment with antibiotics, improved hearing rehabilitation, sound field amplification in classrooms and otosurgical capacity should be further promoted in Greenland.

The present study focused on the comparison of mental health and quality of life (QoL) between chronic otitis media (COM) patients and the hearing population. The patients with chronic otitis media and healthy control group were enrolled in the study. The duration and severity of the auditory impairment were recorded. In addition to hearing loss (HL), the findings of each patient's other ear disorders (ear discharge and tinnitus) were also recorded. In both the groups, psychological symptom profile and health-related QoL were evaluated and compared using a sociodemographic questionnaire, the Symptom Check List 90-Revised Form (SCL-90-R), and the Short Form-36 (SF-36). According to SCL-90-R, somatization (p < 0.001), interpersonal sensitivity (p < 0.001), depression (p < 0.001), phobic anxiety (p < 0.001), and other subscores, and also global severity index score (p < 0.001) were significantly high in patient group when compared to the control group. The patients with COM reported significantly lower levels of QoL in terms of physical role difficulty (p < 0.001), general health perception (p < 0.004), social functioning (p < 0.001), and mental health (p < 0.017) than those of control subjects. Our results indicated that COM patients with mild or moderate HL have poorer life quality and higher psychological problems. Psychological well being should be also considered in assessment of COM patients in addition to the clinical evaluation and audiological tests.

Antibiotics for otitis media with effusion in children.

Otitis media with effusion (OME) is characterised by an accumulation of fluid in the middle ear behind an intact tympanic membrane, without the symptoms or signs of acute infection. In approximately one in three children with OME, however, a bacterial pathogen is identified in the middle ear fluid. In most cases, OME causes mild hearing impairment of short duration. When experienced in early life and when episodes of (bilateral) OME persist or recur, the associated hearing loss may be significant and have a negative impact on speech development and behaviour. Since most cases of OME will resolve spontaneously, only children with persistent middle ear effusion and associated hearing loss potentially require treatment. Previous Cochrane reviews have focused on the effectiveness of ventilation tube insertion, adenoidectomy, autoinflation, antihistamines, decongestants, and oral and topical intranasal steroids in OME. This review focuses on the effectiveness of antibiotics in children with OME. To assess the effects of antibiotics in children up to 18 years with OME. We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 22 February 2012. Randomised controlled trials comparing oral antibiotics with placebo, no treatment or therapy of unproven effectiveness. Our primary outcome was complete resolution of OME at two to three months. Secondary outcomes included resolution of OME at other time points, hearing, language and speech, ventilation tube insertion and adverse effects. Two authors independently extracted data using standardised data extraction forms and assessed the quality of the included studies using the Cochrane 'Risk of bias' tool. We presented dichotomous results as risk differences as well as

Impact of respiratory disease, diarrhea, otitis and arthritis on mortality and carcass traits in white veal calves

2013-01-01

Background Little is known on the effects of common calf diseases on mortality and carcass traits in the white veal industry (special-fed veal), a highly integrated production system, currently criticized for the intensive pro- and metaphylactic use of antimicrobials. The objective of the present study was to determine the impact of bovine respiratory disease (BRD), diarrhea, arthritis and otitis on the economically important parameters of mortality, hot carcass weight (HCW), carcass quality, fat cover and meat color. For this purpose, a prospective study on 3519 white veal calves, housed in 10 commercial herds, was conducted. Case definitions were based on clinical observation by the producers and written treatment records were used. Results Calves received oral antimicrobial group treatments in the milk during 25.2% of the production time on average. With an increasing percentage of the production cycle spent on oral antimicrobials, HCW reduced, whereas the odds for insufficient fat cover or an undesirable red meat color both decreased. Of the calves, 14.8%, 5.3%, 1.5% and 1.6% were individually diagnosed and treated for BRD, diarrhea, arthritis and otitis, respectively. Overall, 5.7% of the calves died and the mortality risk was higher in the first weeks after arrival. Calves that experienced one BRD episode showed a 8.2 kg reduction in HCW, a lower fat cover and an increased mortality risk (hazard ratio (HR) = 5.5), compared to calves which were not individually diagnosed and treated for BRD. With an increasing number of BRD episodes, these losses increased dramatically. Additionally, calves, which experienced multiple BRD episodes, were more likely to have poor carcass quality and an undesirable red meat color at slaughter. Arthritis increased the mortality risk (HR = 3.9), and reduced HCW only when associated with BRD. Otitis did only increase the mortality risk (HR = 7.0). Diarrhea severely increased the mortality risk (HR = 11.0), reduced

Evidence and evidence gaps in the treatment of Eustachian tube dysfunction and otitis media

PubMed Central

Teschner, Magnus

2016-01-01

Evidence-based medicine is an approach to medical treatment intended to optimize patient-oriented decision-making on the basis of empirically proven effectiveness. For this purpose, a classification system has been established to categorize studies – and hence therapy options – in respect of associated evidence according to defined criteria. The Eustachian tube connects the nasopharynx with the middle ear cavity. Its key function is to ensure middle ear ventilation. Compromised ventilation results in inflammatory middle ear disorders. Numerous evidence-based therapy options are available for the treatment of impaired middle ear ventilation and otitis media, the main therapeutic approach being antibiotic treatment. More recent procedures such as balloon dilation of the Eustachian tube have also shown initial success but must undergo further evaluation with regard to evidence. There is, as yet, no evidence for some of the other long-established procedures. Owing to the multitude of variables, the classification of evidence levels for various treatment approaches calls for highly diversified assessment. Numerous evidence-based studies are therefore necessary in order to evaluate the evidence pertaining to existing and future therapy solutions for impaired middle ear ventilation and otitis media. If this need is addressed, a wealth of implications can be expected for therapeutic approaches in the years to come. PMID:28025605

2015-01-01

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. PMID:26492256

Objectives (1) Describe longitudinal trends in annual prevalence of hospital admission for pediatric acute otitis media (AOM) and complications of AOM (CAOM) since introduction of pneumococcal vaccination in 2000 and (2) describe the longitudinal trend of prevalence of hospital admission for pneumococcal meningitis in children with AOM-related diagnoses in the postvaccination era. Study Design Retrospective analysis of Kids' Inpatient Database from 2000 to 2012. Setting Community, nonrehabilitation hospitals. Subjects and Methods To determine annual prevalence of admission for AOM/CAOM, nationally weighted frequencies of children aged <21 years with acute suppurative otitis media, acute mastoiditis, suppurative labyrinthitis, and/or acute petrositis were collected. The frequency of coexisting pneumococcal meningitis diagnoses among these patients was also collected. Trend analysis of prevalences of admission for AOM/CAOM and for pneumococcal meningitis occurring in the setting of AOM/CAOM from 2000 to 2012 was performed. Results Between 2000 and 2012, annual prevalence of admission for AOM/CAOM decreased from 3.956 to 2.618 per 100,000 persons ( P < .0001) (relative risk reduction 34%). Declines in admission prevalence were most pronounced in children <1 year of age (from 22.647 to 8.715 per 100,000 persons between 2000 and 2012, P < .0001) and 1 to 2 years of age (from 13.652 to 5.554 per 100,000 persons between 2000 and 2012, P < .0001). For all ages, the admission prevalence for pneumococcal meningitis and concomitant AOM/CAOM decreased (from 1.760 to 0.717 per 1,000,000 persons, P < .0001) over the study period. Conclusions The prevalence of hospital admission for pediatric AOM/CAOM has declined since the advent of pneumococcal vaccination. Admission rates for pneumococcal meningitis with AOM/CAOM have similarly declined.

Reducing the frequency of acute otitis media by individualized care.

We sought to determine if use of more stringent diagnostic criteria for acute otitis media (AOM) than currently advocated by the American Academy of Pediatrics, tympanocentesis and pathogen-specific antibiotic treatment (individualized care) would result in reducing the incidence of recurrent AOM and consequent tympanostomy tube surgery. A 5-year longitudinal, prospective study in Rochester, NY, was conducted from July 2006 to July 2011 involving 254 individualized care children. When this individualized care group developed symptoms of AOM, strict diagnostic criteria were applied and a tympanocentesis was performed. Pathogen resistance to empiric high-dose amoxicillin/clavulanate (80 mg/kg of amoxicillin component) caused a change in antibiotic to an optimized choice. Legacy controls (n = 208) were diagnosed with the same diagnostic criteria by the same physicians as the individualized care group and received the same empiric amoxicillin/clavulanate (80 mg/kg of amoxicillin component) but no tympanocentesis or change in antibiotic. Community control children (n = 1020) were diagnosed according to current American Academy of Pediatrics guidelines and treated with high-dose amoxicillin (80 mg/kg) without tympanocentesis as guideline recommended. 5.9% of children of the individualized care group compared with 14.4% of Legacy controls and 27.3% of community controls became otitis prone, defined as 3 episodes of AOM within a 6-month time span or 4 AOM episodes within a 12-month time span (P < 0.0001). 2.4% of the individualized care group compared with 6.3% of Legacy controls, and 14.8% of community controls received tympanostomy tubes (P < 0.0001). Individualized care of AOM significantly reduces the frequency of AOM and tympanostomy tube surgery. Use of strict diagnostic criteria for AOM and empiric antibiotic treatment using evidence-based knowledge of circulating otopathogens and their antimicrobial susceptibility profile also produces improved outcomes.

Primary: to compare one-off administration of boric acid powder with courses of 1% acetic acid and ciprofloxacin eardrops in treating active chronic otitis media. Secondary: to evaluate the effectiveness of Quadriderm® cream in resistant active chronic otitis media; and to document side effects of these treatments, especially hearing loss. Randomised controlled trial. Outpatient department of a tertiary ENT unit. Hundred and fifty-nine patients over 6 years old with active chronic mucosal (without cholesteatoma) otitis media randomised to receive one of the three primary agents. All techniques employed were suitable for primary healthcare givers as well as specialists. After confirming eligibility, patients were randomly allocated to treatment. All ears underwent toilet with irrigation using clean water, a syringe and ambient light, with or without dry mopping, until the perforation was visible. The randomised solution was flushed through the middle ear and eustachian tube using a 'tragal pump' technique: saline was used as the solution for flushing in the boric acid powder arm. Patients allocated topical ear medication were given a bottle of eardrops to administer (six drops twice daily, 'pumped in') until finished. Those allocated boric acid powder had the external ear canals filled as a one-off treatment. Patients were followed up monthly thereafter. Primary: Dry (inactive) middle ears as assessed by the doctor. Secondary: Patient assessment of success; microbiologic culture and sensitivity; audiologic changes because of treatment; complications of treatment; costs of therapies. Ciprofloxacin eardrops and boric acid powder were statistically superior to 1% acetic acid eardrops in rendering active chronic otitis media inactive (73% dry ears for ciprofloxacin; 67% for boric acid powder; and 24% for acetic acid). There was no difference between the success rates of ciprofloxacin eardrops and boric acid powder. Quadriderm cream was effective in 85% of patients

Acute otitis media in children is an emergency ENT pathology encountered not only by otorhinolaryngologists but also in the practical work of general pediatrists, infectionists, allergologists, and representatives of other medical disciplines. Retrospective analysis demonstrates a progressively increasing ENT morbidity rate, especially that of non-purulent forms. Clinical and laboratory characteristics of 130 emergency patients examined in the present study using PCR-testing and bacteriological methods provided data on the activity of Streptococci, Mycoplasmas, Chlamidiae, viruses, and other causative agents of ENT diseases. A strategy for the combined treatment of patients with ENT pathology in an infectious department under control of an otorhinolaryngologist is proposed taking into consideration etiology and pathogenesis of the disease.

Background. Chronic suppurative otitis media (CSOM) remains one of the most common childhood chronic infectious diseases worldwide, affecting diverse racial and cultural groups in both developing and industrialized countries. Aim of the Study. This study aimed to assess the impact of educational program on the management of children with CSOM. Subjects and Methods. An experimental study design was used. This study included 100 children of both sexes of 2 years and less of age with CSOM. Those children were divided into 3 groups: group I: it involved 50 children with CSOM (naive) who received the designed educational program; control group: it involved 50 children who were under the traditional treatment and failed to respond; group II: those children in the control group were given the educational program and followed up in the same way as group I and considered as group II. Tools of the Study. Tool I is a structured questionnaire interview sheet for mothers. It consists of four parts: (1) personal and sociodemographic characteristics of child and (2) data about risk factors of otitis media (3) assessment of maternal practice about care of children with suppurative otitis medi (4) diagnostic criteria for suppurative otitis media. Tool II is the educational program: an educational program was developed by the researchers based on the knowledge and practices needs. This study was carried out through a period of 9 months starting from September 2013 to May 2014. The educational program was implemented for mothers of children with CSOM in the form of 5 scheduled sessions at the time of diagnosis, after one week, 1, 3, and 6 months. Results. There were significant differences between children who received the educational program and control group regarding the response to treatment after one and 3 months. The percentages of complete cure increased progressively 32%, 60%, and 84% after 1, 3, and 6 months in group I while they were 24%, 44%, and 64% in group II

Recurrent otitis media with effusion (OME) is a leading cause of acquired hearing loss in childhood. Histological chorioamnionitis (HCA) is an important cause of preterm delivery and neonatal morbidity and mortality. Here, we tested the hypothesis of an association between recurrent OME during the first 3 years of life and HCA in very low birth weight (VLBW) infants. A total of 110 randomly selected VLBW preterm newborns with HCA and 135 gestational age and gender-matched, HCA-negative VLBW infants were evaluated prospectively during the first 3 years of life for the presence of OME, as diagnosed on the basis of otoscopy, type B or C tympanogram, ipsilateral absence of transient evoked otoacoustic emissions responses, and ipsilaterally increased threshold at diagnostic auditory brain responses evaluation. Potential risk factors for OME were also examined in the two groups. The HCA-positive infants showed a approximately six times higher frequency of recurrent OME (P<0.0001), increased frequency (>5/yr) of clinical otitis media episodes (P=0.000020), approximately five times higher frequency of adenoid hypertrophy (P<0.00001), a significant seasonal pattern of birth with autumn predominance (P<0.00001), and the first OME occurred earlier (P<0.0001), as compared to the HCA-negative counterparts. Recurrent OME was significantly associated with HCA (O.R.=17.76, 95% CI: 8.98-35.13, P<0.00001), adenoid hypertrophy (O.R.=9.96, 95% CI: 5.17-19.18, P<0.00001), frequency of acute otitis episodes >5/yr (O.R.=8.91, 95% CI: 1.96-40.41, P=0.0005), and birth in autumn (O.R.=5.58, 95% CI: 2.79-11.12, P<0.00001). These findings indicate that HCA is a previously unrecognized risk factor for the development of recurrent bilateral OME in VLBW preterm infants during the first 3 years of life.

A case of Haemophilus parainfluenzae meningitis in a woman with a 3-day history of acute otitis media is reported. Her medical history included bladder cancer surgery. Unequivocal identification of the isolate was obtained by using molecular techniques such as 16S rRNA sequencing besides to conventional culture methods. To investigate bacterial virulent traits possibly related to invasive properties, in vitro serum resistance of our isolate was analyzed, but it was found serum susceptible. Our study demonstrates that H. parainfluenzae can be considered an opportunistic pathogen able to cause life-threatening infections not only in children but also in patients with underlying conditions.

Lemierre's syndrome is a rare clinical condition that generally develops secondary to oropharyngeal infection caused by Fusobacterium necrophorum, which is an anaerobic bacteria. A 62-year-old patient with diabetes mellitus presented with internal jugular vein and sigmoid sinus-transverse sinus thrombophlebitis, accompanying otitis media and mastoiditis that developed after an upper airway infection. Interestingly, there were air bubbles in both the internal jugular vein and transverse sinus. Vancomycin and meropenem were started and a right radical mastoidectomy was performed. The patient's clinical picture completely resolved in 14 days. High mortality and morbidity may be prevented with a prompt diagnosis of Lemierre's syndrome. PMID:25431696

Influenza A virus (IAV) predisposes individuals to secondary infections with the bacterium Streptococcus pneumoniae (the pneumococcus). Infections may manifest as pneumonia, sepsis, meningitis, or otitis media (OM). It remains controversial as to whether secondary pneumococcal disease is due to the induction of an aberrant immune response or IAV-induced immunosuppression. Moreover, as the majority of studies have been performed in the context of pneumococcal pneumonia, it remains unclear how far these findings can be extrapolated to other pneumococcal disease phenotypes such as OM. Here, we used an infant mouse model, human middle ear epithelial cells, and a series of reverse-engineered influenza viruses to investigate how IAV promotes bacterial OM. Our data suggest that the influenza virus HA facilitates disease by inducing a proinflammatory response in the middle ear cavity in a replication-dependent manner. Importantly, our findings suggest that it is the inflammatory response to IAV infection that mediates pneumococcal replication. This study thus provides the first evidence that inflammation drives pneumococcal replication in the middle ear cavity, which may have important implications for the treatment of pneumococcal OM.

Gastroesophageal reflux is considered a risk factor for recurrent or persistent upper and lower respiratory tract conditions including asthma, chronic cough, sinusitis, laryngitis, serous otitis and paroxysmal laryngospasm. Fifty-one subjects with recurrent (more than three) episodes of upper respiratory tract infection (URTI), serous otitis or sinusitis who had been admitted to an earnose- throat (ENT) outpatient clinic during the previous year were enrolled in the present study to evaluate the presence of laryngeal and/or esophageal reflux. The participants, who were randomly selected, were questioned about symptoms of reflux, including vomiting, abdominal pain, failure to thrive, halitosis, bitter taste in the mouth, chronic cough, heartburn, constipation and hoarseness. All subjects had an endoscopic examination, an otoscopic examination, a tympanogram and upper GI system endoscopy. Esophagitis was diagnosed endoscopically and histologically. The likelihood of occurrence of esophagitis was found to be higher only among subjects with postglottic edema/erythema as determined by pathological laryngeal examination. The reflux complaints reported did not predict the development of esophagitis, but the odds of esophagitis occurring were ninefold greater among subjects with recurrent otitis. Of the subjects, 45.1% were Helicobacter pylori-positive. However, no association was found between esophagitis and Helicobacter pylori positivity. The likelihood of the occurrence of esophagitis was found to be increased in the presence of recurrent otitis media and/or postglottic edema, irrespective of the presence of reflux symptoms. We concluded that, in contrast to the situation where adults are concerned, the boundaries for discriminating laryngopharyngeal reflux from gastroesophageal reflux are somewhat blurred in pediatric patients.

A female aged 9 years with a recent episode of acute otitis media (AOM) presented to her primary care physician with complaints of severe abdominal pain with right lower quadrant rebound tenderness, suggestive of an acute surgical abdomen. Neurological examination was normal on presentation. She was transferred to the local children's hospital for workup of appendicitis, during which she began exhibiting ataxia and slurred speech. Further evaluation revealed mastoiditis, venous sinus thrombosis and subdural empyema. Appendicitis was ruled out. We describe the first documented case of neurological complications of AOM presenting as an acute surgical abdomen without initial neurological findings. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Streptococcus pneumoniae is the most frequent microbe causing middle ear infection. The pathophysiology of pneumococcal otitis media has been characterized by measurement of local inflammatory mediators such as inflammatory cells, lysozyme, oxidative metabolic products, and inflammatory cytokines. The role of cytokines in bacterial infection has been elucidated with animal models, and interleukin (IL)-1β, IL-6, and IL-8 and tumor necrosis factor alpha (TNF-α) are recognized as being important local mediators in acute inflammation. We characterized middle ear inflammatory responses in the chinchilla otitis media model after injecting a very small number of viable pneumococci into the middle ear, similar to the natural course of infection. Middle ear fluid (MEF) concentrations of IL-1β, IL-6, IL-8, and TNF-α were measured by using anti-human cytokine enzyme-linked immunosorbent assay reagents. IL-1β showed the earliest peak, at 6 h after inoculation, whereas IL-6, IL-8, and TNF-α concentrations were increasing 72 h after pneumococcal inoculation. IL-6, IL-8, and TNF-α but not IL-1β concentrations correlated significantly with total inflammatory cell numbers in MEF, and all four cytokines correlated significantly with MEF neutrophil concentration. Several intercytokine correlations were significant. Cytokines, therefore, participate in the early middle ear inflammatory response to S. pneumoniae. PMID:10085040

Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

Otitis media (OM) is one of the most common childhood diseases. OM can arise when a viral infection enables bacteria to disseminate from the nasopharynx to the middle ear. Here, we provide the first infant murine model for disease. Mice coinfected with Streptococcus pneumoniae and influenza virus had high bacterial load in the middle ear, middle ear inflammation, and hearing loss. In contrast, mice colonized with S. pneumoniae alone had significantly less bacteria in the ear, minimal hearing loss, and no inflammation. Of interest, infection with influenza virus alone also caused some middle ear inflammation and hearing loss. Overall, this study provides a clinically relevant and easily accessible animal model to study the pathogenesis and prevention of OM. Moreover, we provide, to our knowledge, the first evidence that influenza virus alone causes middle ear inflammation in infant mice. This inflammation may then play an important role in the development of bacterial OM. PMID:21930608

We present a case report of a four-year-old boy with torcicollis and trismus after acute otitis media. Grisel Syndrome diagnosis in association with temporo-mandibular reactive arthritis was admitted, leading to early conservative treatment. GS should be suspected in a child presenting with torticollis after an upper respiratory tract infection or an ENT surgical procedure. The association with temporo-mandibular reactive findings is somehow rarer but not impossible, due to the close vascular communication between retropharyngeal and pterigoid spaces.

Moraxella catarrhalis (Mcat) is a prominent mucosal pathogen causing acute otitis media (AOM). We studied Mcat nasopharyngeal (NP) colonization, AOM frequency and mucosal antibody responses to four vaccine candidate Mcat proteins: outer membrane protein (OMP) CD, oligopeptide permease (Opp) A, hemagglutinin (Hag), and Pilin A clade 2 (PilA2) from stringently defined otitis prone (sOP) children, who experience the greatest burden of disease, compared to non-otitis prone (NOP) children. sOP children had higher NP colonization of Mcat (30 vs. 22%, P = 0.0003) and Mcat-caused AOM rates (49 vs. 24%, P < 0.0001) than NOP children. Natural acquisition of mucosal antibodies to Mcat proteins OMP CD (IgG, P < 0.0001), OppA (IgG, P = 0.018), Hag (IgG and IgA, both P < 0.0001), and PilA2 (IgA, P < 0.0001) was lower in sOP than NOP children. Higher levels of mucosal IgG to Hag (P = 0.039) and PilA2 (P = 0.0076), and IgA to OMP CD (P = 0.010), OppA (P = 0.030), and PilA2 (P = 0.043) were associated with lower carriage of Mcat in NOP but not sOP children. Higher levels of mucosal IgG to OMP CD (P = 0.0070) and Hag (P = 0.0003), and IgA to Hag (P = 0.0067) at asymptomatic colonization than those at onset of AOM were associated with significantly lower rate of Mcat NP colonization progressing to AOM in NOP compared to sOP children (3 vs. 26%, P < 0.0001). In conclusion, sOP children had a diminished mucosal antibody response to Mcat proteins, which was associated with higher frequencies of asymptomatic NP colonization and NP colonization progressing to Mcat-caused AOM. Enhancing Mcat antigen-specific mucosal immune responses to levels higher than achieved by natural exposure will be necessary to prevent AOM in sOP children. PMID:28848555

Vemurafenib ha probado ser una herramienta útil en el tratamiento de melanoma metastásico con mutación BRAF-V600E. Los efectos adversos incluyen artralgias, fatiga y toxicidad cutánea, siendo infrecuente la paniculitis. Presentamos el caso de una paciente de 43 años con melanoma metastásico que desarrolla lesiones subcutáneas dolorosas en miembros inferiores y superiores, asociadas a clínica sistémica después de 2 semanas de inicio de tratamiento con Vemurafenib + Cobimetinib. La histología demostró paniculitis linfocitaria septal y lobulillar. La paciente tuvo mala tolerancia al tratamiento anti diana a dosis plenas, requiriendo su ajuste, generando una corticodependencia para controlar sintomatología, y que finalmente obligó a la descontinuación de la terapia dirigida contra melanoma.  A la fecha, se han descrito 29 casos en la literatura de paniculitis asociada a vemurafenib, siendo la mayoría paniculitis neutrofílicas con adecuado control de sintomatología asociando antiinflamatorios no esteroidales y/o corticoides orales sin requerir en su mayoría modificación de la terapia contra melanoma; sin embargo hay que tener presente que pueden haber casos con mala evolución que obligan a la reducción de dosis de vemurafenib y descontinuar el tratamiento, como ha ocurrido en nuestro reporte.Vemurafenib has proven to be a useful tool in the treatment of metastatic melanoma with BRAF-V600E mutation.

Winter, Linda E; Barenkamp, Stephen J

2017-10-01

Outer membrane vesicles (OMVs) produced by Gram-negative bacteria are enriched in several outer membrane components, including major and minor outer membrane proteins and lipooligosaccharide. We assessed the functional activity of nontypeable Haemophilus influenzae (NTHi) OMV-specific antisera and the protective ability of NTHi OMVs as vaccine antigens in the chinchilla otitis media model. OMVs were purified from three HMW1/HMW2-expressing NTHi strains, two of which were also engineered to overexpress Hia proteins. OMV-specific antisera raised in guinea pigs were assessed for their ability to mediate killing of representative NTHi in an opsonophagocytic assay. The three OMV-specific antisera mediated killing of 18 of 65, 24 of 65, and 30 of 65 unrelated HMW1/HMW2-expressing NTHi strains. Overall, they mediated killing of 39 of 65 HMW1/HMW2-expressing strains. The two Hia-expressing OMV-specific antisera mediated killing of 17 of 25 and 14 of 25 unrelated Hia-expressing NTHi strains. Overall, they mediated killing of 20 of 25 Hia-expressing strains. OMVs from prototype NTHi strain 12 were used to immunize chinchillas and the course of middle ear infection was monitored following intrabullar challenge with the homologous strain. All control animals developed culture-positive otitis media, as did two of three HMW1/HMW2-immunized animals. All OMV-immunized animals, with or without supplemental HMW1/HMW2 immunization, were completely protected against otitis media. NTHi OMVs are the first immunogens examined in this model that provided complete protection with sterile immunity after NTHi strain 12 challenge. These data suggest that NTHi OMVs hold significant potential as components of protective NTHi vaccines, possibly in combination with HMW1/HMW2 proteins.

Sempervivum tectorum L. (Crassulaceae), known as houseleek, is used in traditional medicine in the treatment of ear inflammation. It can be spread as a pack on wounds, sores, burns, and abscesses and also on painful areas attacked by gout as a refrigerant and astringent. Drinking tea prepared from leaves of S. tectorum is recommended for ulcer treatment. The present study was designed to investigate ethopharmacological use of S. tectorum in the southern Serbia and to further scientifically justify and confirm effectiveness of the leaf juice used in ethnomedicine for ear inflammation, against otitis linked bacteria. Ethnopharmacological survey on the use of S. tectorum in southern Serbia was performed using semi structured questionnaires via a face-to-face interview. Chemical composition of the leaf juice regarding phenolic compounds and organic acids was analyzed. Antimicrobial activity was tested on bacteria isolated from ear swabs of the patients suffering from the ear pain (otitis). Anti-quorum-sensing activities of the juice were further investigated on Pseudomonas aeruginosa. Ethnopharmacological survey revealed the use of S. tectorum in southern Serbia for the treatment of ear pain, warts, cancer, stomachache, ulcer and high blood sugar level with the highest fidelity level (FL) for the ear pain. The phenolic composition of the S. tectorum leaf juice consisted of flavonol glycosides, with kaempferol-3-O-rhamnosyl-glucoside-7-O-rhamnoside as the majority compound. Organic acids composition revealed malic acid as the most dominant one. Antimicrobial and anti-quorum-sensing activities of the juice showed to be promising. Ethnopharmacological use of S. tectorum juice for treating ear pain is justified, since the juice possessed antimicrobial activity towards clinical isolates of bacteria linked to otitis.

2010-01-01

Objectives/Hypothesis The inner ear is at risk for sensorineural hearing loss in both acute and chronic otitis media (OM), but the underlying mechanisms underlying sensorineural hearing loss are unknown. Previous gene expression array studies showed cytokine genes might be upregulated in the cochleas of mice with acute and chronic otitis media. This implies that the inner ear could manifest a direct inflammatory response to OM that may cause sensorineural damage. Therefore, to better understand inner ear cytokine gene expression during OM, quantitative RT-PCR and immunohistochemistry were performed on mouse models to evaluate middle and inner ear inflammatory and remodeling cytokines. Study Design Basic science experiment. Methods An acute OM model was created in Balb/c mice by a transtympanic injection of S. pneumoniae in one ear; the other ear used as a control. C3H/HeJ mice were screened for unilateral chronic OM with the non-infected ear serving as control. Results Both acute and chronic OM caused both the middle ear and inner tissues in these two mouse models to over express numerous cytokine genes related to tissue remodeling (TNFα, FGF, BMP) and angiogenesis (VEGF), as well as inflammatory cell proliferation (IL-1α,β, IL-2, IL-6). Immunohistochemistry confirmed that both the middle ear and inner ear tissues expressed these cytokines. Conclusion Cochlear tissues are capable of expressing cytokine mRNA that contributes to the inflammation and remodeling that occur in association with middle ear disease. This provides a potential molecular basis for the transient and permanent sensorineural hearing loss often reported with acute and chronic OM. Level of Evidence N/A PMID:21271590

In a multicenter study, Augmentin pediatric suspension was given to 1,227 young children (3 months - 3 years) with otitis media seen in private practice. Patterns of otitis included first episodes, recurrences, and forms that had failed to respond to previous antimicrobial therapy. The study medication was given as a first-line treatment, on the basis of epidemiologic data, in a daily dose of 40 mg/kg for 7 to 10 days. In the 3 months to 3 years age group, two micro-organisms are prevalent, ie. Haemophilus influenzae, which is the most common agent and may produce beta-lactamases (10 to 18% of strains), and Streptococcus pneumoniae. Among our patients, the otitis-conjunctivitis syndrome caused by Haemophilus influenzae was fairly frequent (8.7% of cases). Clinical effectiveness as evaluated between D8 and D11 was good or very good in 91.2% of cases. Tolerance was satisfactory in 83% of patients. Side effects were uncommon and consisted primarily in gastrointestinal symptoms. We point out the potentially deleterious effect of concurrent anti-inflammatory treatment. Acceptability of the suspension was judged satisfactory by the parents in 91.6% of cases. Augmentin proved well-suited to epidemiologic data, outstandingly effective, well tolerated, and easy to use because of its presentation as a pediatric suspension; it is therefore an appropriate first-line drug in the common indication addressed in our study.

In malignant external otitis (MEO), determining the anatomic extent of disease and evaluating the physiologic response to therapy remain a problem. Magnetic resonance imaging (MRI) has recently become available in limited clinical settings. Four patients with MEO were evaluated using MRI, computerized tomography (CT), technetium-99 (Tc-99) bone scanning, and gallium-67 citrate (Ga-67 citrate) scanning. MRI is superior to CT, Tc-99 bone scanning, and Ga-67 citrate scanning in evaluating the anatomic extent of soft tissue changes in MEO. MRI alone cannot be relied upon to determine the physiologic response to therapy. MRI can, however, serve as a valuable guide to themore » interpretation of Tc-99 bone and Ga-67 citrate scans, and in this respect, MRI is extremely useful in the treatment of MEO.« less

We describe a very rare case of tuberculous otitis media (TOM) with direct intracranial extension. The patient was a 55-year-old man who presented to our ENT clinic for evaluation of severe headaches and right-sided otorrhea. A biopsy of granulation tissue obtained from the right external auditory canal demonstrated chronic inflammation that was suggestive of mycobacterial infection. Magnetic resonance imaging of the brain indicated intracranial extension of TOM through a destroyed tegmen mastoideum. After 2 months of antituberculous medication, the headaches and otorrhea were controlled, and the swelling in the external ear canal subsided greatly. Rarely does TOM spread intracranially. In most such cases, intracranial extension of tuberculosis occurs as the result of hematogenous or lymphogenous spread. In rare cases, direct spread through destroyed bone can occur, as it did in our patient.

The aim of this study was to compare the effect of boric acid and polymyxin, neomycin and hydrocortisone composition in the treatment of acute otitis externa. This randomized clinical trial was carried out on 80 patients aged more than 17-year-old who were referred to Kashani hospital clinic with a diagnosis of acute otitis externa by otolaryngologist. The patients were randomly allocated to two groups (A: Boric acid and B: polymyxin NH ear drops) and Painkiller was prescribed and administered orally for all patients and in the presence of fever, cellulitis around the ears and neck adenopathy, broad-spectrum systemic antibiotics were used besides topical treatment. Symptoms of patients who were evaluated by a physician includes pain, discharge from the ear, swelling of the ear canal, auricle swelling, tenderness, and ear itching.

Introduction Acute otitis externa is an inflammation of the external auditory canal known as "swimmer’s ear". Direct costs including medical treatment, painkillers, antibiotics, steroids or both and indirect costs are also remarkable. Aim The aim of this study was to compare the effect of boric acid and polymyxin, neomycin and hydrocortisone composition in the treatment of acute otitis externa. Materials and Methods This randomized clinical trial was carried out on 80 patients aged more than 17-year-old who were referred to Kashani hospital clinic with a diagnosis of acute otitis externa by otolaryngologist. The patients were randomly allocated to two groups (A: Boric acid and B: polymyxin NH ear drops) and Painkiller was prescribed and administered orally for all patients and in the presence of fever, cellulitis around the ears and neck adenopathy, broad-spectrum systemic antibiotics were used besides topical treatment.

In this study the reliability and validity of generic and disease-specific questionnaires has been assessed focusing on responsiveness. This is part of a study on the effects of recurrent acute otitis media (rAOM) on functional health status (FHS) and health-related quality of life (HRQoL) in 383 children with rAOM participating in a randomized clinical trial. The following generic questionnaires were studied: 1. RAND general health rating index, 2. Functional Status Questionnaire (FSQ Generic and FSQ Specific), 3. TNO-AZL Infant Quality of Life (TAIQOL), and the following disease-specific questionnaires: 1. Otitis Media-6 (OM-6), 2. Numerical rating scales (NRS) for child and caregiver (NRS Child and NRS Caregiver), and 3. a new Family Functioning Questionnaire (FFQ). Reliability was good to excellent (Cronbach’s α range 0.80–0.90, intraclass correlation coefficient range 0.76–0.93). Moderate to strong correlations were found between the questionnaires as well as between questionnaires and relevant clinical indicators (r = 0.29–0.49), demonstrating construct validity. Discriminant validity for children with few versus frequent episodes of acute otitis media per year was good for most questionnaires (P < 0.004) but poor for the otitis media-related subscales of the TAIQOL (P = 0.10–0.97) and both NRS (P = 0.22 and 0.48). Except for the TAIQOL subscales, change scores were significant (P < 0.003) for generic and disease-specific questionnaires. Effect sizes were somewhat higher for disease-specific compared to generic questionnaires (0.55–0.95 versus 0.32–0.60) except for the TAIQOL subscales, which showed very poor sensitivity to change. Anchor-based methods resulted in a somewhat larger range of estimates of MCID than distribution-based methods. Combining distribution-based and anchor-based methods resulted in similar ranges for the minimally clinical important differences for generic and disease-specific questionnaires: 2–15 points on a

A total of 1,021 children attending 2 primary schools in districts in Erzurum were enrolled in a study evaluating the prevalence of otitis media with effusion (OME) and its relationship with various risk factors. The prevalence of OME in this study was 6.8% (69/1021). The difference in OME prevalence between age groups (<9 years, >9 years) was statistically significant (p<0.05). Parental smoking (p<0.001), history of acute otitis media (AOM) and recent history of upper respiratory tract infection (URTI) (p<0.001), socioeconomic status (p < 0.05), family size (p<0.001), educational status of the parents (p<0.05) and breastfeeding history (p<0.05) were also statistically significant factors. Sex (p>0.05), consanguineous marriage (p>0.05) and history of hearing loss in the parents (p>0.05) were not statistically significant. Parents need to be informed about the symptoms of and risk factors for OME to avoid delayed diagnosis, which can lead to permanent hearing loss.

In a randomized, double-blind, placebo-controlled trial involving 518 infants and children who had otitis media with effusion ("secretory" otitis media), we evaluated the efficacy of a two-week course of amoxicillin (40 mg per kilogram of body weight per day) with and without a four-week course of an oral decongestant-antihistamine combination. Among the 474 subjects who were evaluated at the four-week end point, the rate of resolution of middle-ear effusion was twice as high in those treated with amoxicillin, either with or without the decongestant-antihistamine, as in those who received placebo (P less than 0.001), but 69.8 percent of the amoxicillin-treated subjects still had effusion. Among both the amoxicillin-treated subjects and the placebo-treated subjects, resolution was more likely in those with initially unilateral effusion, in those who had had effusion for eight weeks or less, and in those without an upper respiratory tract infection at the four-week end point. Side effects were reported more often in subjects who received decongestant-antihistamine than in those who did not. Among the subjects without effusion at the four-week end point, recurrent effusion developed in approximately half those in both the amoxicillin and placebo groups during the subsequent three months. We conclude that in infants and children with otitis media with effusion, amoxicillin treatment increases to some extent the likelihood of resolution.

To assess eustachian tubal function (ETF) preoperatively in patients with chronic suppurative otitis media (CSOM) with central perforation by performing the inflation-deflation test. To correlate the results of the inflation-deflation test with the finding of aditus patency or block in patients with CSOM STUDY DESIGN: Prospective, cohort Tertiary care hospital Eighty adult patients with chronic suppurative otitis media and central perforation were recruited into the study. There were 45 males and 35 females. All patients underwent preoperative inflation-deflation test followed by cortical mastoidectomy and tympanoplasty. The patency of the aditus was assessed intraoperatively. Equalization of pressure on inflation-deflation test and intraoperative assessment of aditus patency Of a total of 80 patients, 49 patients were found to have discharging ears and 31 had dry ears at the time of surgery. In dry ears the inflation-deflation test had a sensitivity of 93% in predicting aditus patency although the specificity was lower at 67%. In discharging ears the sensitivity in predicting aditus patency was 72% and the specificity was 67%. The eustachian tube inflation-deflation test is a sensitive test for predicting aditus patency in patients with dry ears but less so in patients with discharging ears. Hence, it could be used in the former to avoid unnecessary exploration of the mastoid.

This study makes an analysis of the effect of Botulinum toxin type A on otitis media with effusion in rats. As part of the study, 24 male Wistar Albino rats were divided into three groups: Group 1: Botulinum toxin Type A and Histamıne (intratympanic 0.2 ml = 20 unit BTA); Group 2: Saline and Histamine (intratympanic 0.2 ml 0.9%); Group 3: Histamine (intratympanic 0.2 ml). Histamine (intratympanic 0.2 ml) was administered into the right ear for all groups. DPOAE and ABR tests were carried out on days 5, 10, 15 and 20 from the beginning of the study. There was no significant difference between DPOAE and ABR scores of the groups. In each group, the DPOAE scores for the right ear significantly decreased on day 5 when compared to the basal scores. In each group, there was no significant difference between days 5, 10 and 15 for the right ear. Botulinum toxin type A blocked the secretion of glands in the middle ear and showed no effect to prevent the formation of serous otitis. In addition, it was found out that Botulinum toxin did not lead to any morphological change in the cochlea.

Resumen Objetivos: obtener estimaciones de indicadores de cobertura de las pensiones por jubilación o retiro para la población mexicana de 65 y más años, y evaluar el impacto que tienen los sistemas de pensiones en las transiciones al retiro de los adultos en edades medias y avanzadas en México. Para ello se utilizan datos microeconómicos provenientes de la Encuesta Nacional de Salud y Envejecimiento. Mediante análisis econométrico se identifican los factores sociodemográficos, económicos, laborales e institucionales que están asociados al acceso a una pensión de jubilación, o bien, a la dependencia de otras fuentes de ingresos. Se encontró que, en México, las transiciones al retiro del mercado de trabajo en las etapas avanzadas del ciclo de vida son limitadas debido a las características eminentemente contributivas de los esquemas de pensiones, los cuales favorecen a la población con trayectorias laborales formales y más estables asociadas a: características de género, oportunidades educativas y posibilidades de inserción en el mercado laboral.

Otitis media is inflammation of the middle ear and tympanic membrane, which often occurs after an acute upper respiratory tract infection. It is the most common episode of infection in children and the second most important cause of hearing loss affecting 1.23 billion people, thus ranked fifth global burden of disease with a higher incidence in sub-Saharan Africa. Thus, the aim of this study was to determine the isolation rate of bacterial pathogens from pediatric patients with otitis media. Institutional based cross-sectional study was conducted from January 2013-June 2014 in Addis Ababa among 210 pediatrics patients. Demographic, clinical and associated factors data was obtained in face to face interview with guardians/parents by 5 trained nurse data collectors using structured questionnaire. Middle ear drainage swab was collected following all aseptic procedures and transported to the microbiology laboratory. Culture and Antimicrobial sensitivity test were performed according to the standards. The data quality was assured by questionnaire translation, retranslation and pretesting. Reference strains were used as a positive and negative control for biochemical tests, and culture results were cross checked. Data was checked for completeness, consistency and then entered into Epi Info v3.5.1 and analyzed by SPSS v20. Data interpretation was made using graphs, tables, and result statements. A total of 196 middle ear drainage swab samples were analyzed from pediatric patients and of those 95 (48.5%) samples were positive for pathogenic organisms. The major isolate was S. aureus (15.8%) followed by P. aeruginosa (10.9%), Viridians streptococcus (9.9%), S. pneumoniae (8.9%) and S. pyogenes (7.9%). Upper respiratory tract infection history and living in the rural area have shown significant association with the isolation of pathogenic organism, ( p-value = 0.035) and ( p-value = 0.003) respectively. Most of the isolates show a high level of resistance to

Background The exact role of High resolution computed tomography (HRCT) temporal bone in preoperative assessment of Chronic suppurative otitis media atticoantral disease still remains controversial. Objective To evaluate the role of high resolution computed tomography temporal bone in Chronic suppurative otitis media atticoantral disease and to compare preoperative computed tomographic findings with intra-operative findings. Method Prospective, analytical study conducted among 65 patients with chronic suppurative otitis media atticoantral disease in Department of Radiodiagnosis, Kathmandu University Dhulikhel Hospital between January 2015 to July 2016. The operative findings were compared with results of imaging. The parameters of comparison were erosion of ossicles, scutum, facial canal, lateral semicircular canal, sigmoid and tegmen plate along with extension of disease to sinus tympani and facial recess. Sensitivity, specificity, negative predictive value, positive predictive values were calculated. Result High resolution computed tomography temporal bone offered sensitivity (Se) and specificity (Sp) of 100% for visualization of sigmoid and tegmen plate erosion. The performance of HRCT in detecting malleus (Se=100%, Sp=95.23%), incus (Se=100%,Sp=80.48%) and stapes (Se=96.55%, Sp=71.42%) erosion was excellent. It offered precise information about facial canal erosion (Se=100%, Sp=75%), scutum erosion (Se=100%, Sp=96.87%) and extension of disease to facial recess and sinus tympani (Se=83.33%,Sp=100%). high resolution computed tomography showed specificity of 100% for lateral semicircular canal erosion (Sp=100%) but with low sensitivity (Se=53.84%). Conclusion The findings of high resolution computed tomography and intra-operative findings were well comparable except for lateral semicircular canal erosion. high resolution computed tomography temporal bone acts as a road map for surgeon to identify the extent of disease, plan for appropriate procedure that is

Streptococcus salivarius K12 (BLIS K12) is a probiotic strain strongly antagonistic to the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. Shown to colonize the oral cavity and to be safe for human use, BLIS K12 has previously been reported to reduce pharyngo-tonsillitis episodes in children or adults known to have experienced recurrent streptococcal infection. The present study was focussed upon evaluating the role of BLIS K12 in the control of streptococcal disease and acute otitis media in children attending the first year of kindergarten. By randomization, 222 enrolled children attending the first year of kindergarten were divided into a treated group (N = 111) receiving for 6 months a daily treatment with BLIS K12 (Bactoblis®) and a control group (N = 111) who were monitored as untreated controls. During the 6 months of treatment and 3 months of follow-up, the children were evaluated for treatment tolerance, and for episodes of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media. During the 6-month trial (N = 111 per group) the incidence of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media was approximately 16%, 9% and 44% respectively in the treated group and 48%, 4% and 80% in the control group. During the 3-months follow-up (N = 29 per group) the corresponding rates of infection were 15%, 0% and 12% in the treated group and 26%, 6% and 36% in the controls. No apparent side effects were detected in the treated group either during treatment or follow-up. All of the enrolled children completed the study. The daily administration of BLIS K12 to children attending their first year of kindergarten was associated with a significant reduction in episodes of streptococcal pharyngitis and acute otitis media. No protection against scarlet fever was detected.

The clinical data of 4,012 cases of CSOM treated with surgery were analyzed retrospectively, including age, sex, operation time, surgical approach, time of ocular symptoms presentation, duration of ocular symptoms, treatment and prognosis. Among the 4,012 cases, 109 patients (2.72%) developed ocular complication, of which 68.81% (75/109) suffered from blurred vision, 24.77% (27/109) presented only erythema on eyelids or mild periorbital edema, 4.59% (5/109) had erythema on eyelids with periorbital edema, and 1.83% (2/109) complained of periorbital ecchymosis and edema. All of these complications recovered themselves without any sequela. Ocular complications following surgery of CSOM are rarely reported. Pre-auricular incision and fascia harvesting, turbulence of venous and lymphatic drainage and preseptal cellulitis might be the risk factors. Blurred vision might be associated with eye injury during surgery and the use of anticholinergic agent.

Moraxella catarrhalis ( Mcat ) is a prominent mucosal pathogen causing acute otitis media (AOM). We studied Mcat nasopharyngeal (NP) colonization, AOM frequency and mucosal antibody responses to four vaccine candidate Mcat proteins: outer membrane protein (OMP) CD, oligopeptide permease (Opp) A, hemagglutinin (Hag), and Pilin A clade 2 (PilA2) from stringently defined otitis prone (sOP) children, who experience the greatest burden of disease, compared to non-otitis prone (NOP) children. sOP children had higher NP colonization of Mcat (30 vs. 22%, P  = 0.0003) and Mcat -caused AOM rates (49 vs. 24%, P  < 0.0001) than NOP children. Natural acquisition of mucosal antibodies to Mcat proteins OMP CD (IgG, P  < 0.0001), OppA (IgG, P  = 0.018), Hag (IgG and IgA, both P  < 0.0001), and PilA2 (IgA, P  < 0.0001) was lower in sOP than NOP children. Higher levels of mucosal IgG to Hag ( P  = 0.039) and PilA2 ( P  = 0.0076), and IgA to OMP CD ( P  = 0.010), OppA ( P  = 0.030), and PilA2 ( P  = 0.043) were associated with lower carriage of Mcat in NOP but not sOP children. Higher levels of mucosal IgG to OMP CD ( P  = 0.0070) and Hag ( P  = 0.0003), and IgA to Hag ( P  = 0.0067) at asymptomatic colonization than those at onset of AOM were associated with significantly lower rate of Mcat NP colonization progressing to AOM in NOP compared to sOP children (3 vs. 26%, P  < 0.0001). In conclusion, sOP children had a diminished mucosal antibody response to Mcat proteins, which was associated with higher frequencies of asymptomatic NP colonization and NP colonization progressing to Mcat -caused AOM. Enhancing Mcat antigen-specific mucosal immune responses to levels higher than achieved by natural exposure will be necessary to prevent AOM in sOP children.

The objective of the present study was to estimate the therapeutic efficacy and safety of the topically applied otinum ear drops. The authors present the results of the combined treatment of acute catarrhal otitis in the children with the use of choline salicilate (otinum). The study included 50 patients randomized into two identical groups. The children of group 1 received systemic therapy supplemented by the topical application of otinum, those in group 2 were prescribed a 3% alcoholic solution of boric acid. The study has demonstrated a significantly more pronounced positive dynamics of clinical conditions in the patients of group 1 compared with those of the control group. The total duration of therapy in the first group was 37.5% shorter than in the second. The results of the study confirmed the strong anti-inflammatory and analgesic action of choline salicilate. The pain was relieved within 7 minutes on the average after the application of this agent. It is concluded that otinum can be recommended for the introduction into combined therapy of acute catarrhal otitis media as an efficacious anti-inflammatory and analgetic drug.

ABSTRACT The aim of the study was to analyze the bacteriome of acute otitis media with a novel modification of next-generation sequencing techniques. Outpatient children with acute otitis media were enrolled in the study, and middle ear fluids were collected during 90 episodes from 79 subjects aged 5 to 42 months (median age, 19 months). The bacteriome profiles of middle ear fluid samples were determined by a nested-PCR amplification of the 16S rRNA gene (V4 region), followed by mass sequencing. The profiling results were compared to the results of specific PCR assays targeting selected prevalent pathogens. Bacteriome profiling using nested amplification of low-volume samples was aided by a bioinformatic subtraction of signal contaminants from the recombinant polymerase, achieving a sensitivity slightly lower than that of specific PCR detection. Streptococcus pneumoniae was detected in 28 (31%) samples, Haemophilus influenzae in 24 (27%), Moraxella catarrhalis in 18 (20%), Staphylococcus spp. in 21 (23%), Turicella otitidis in 5 (5.6%), Alloiococcus otitidis in 3 (3.3%), and other bacteria in 14 (16%) using bacteriome profiling. S. pneumoniae was the dominant pathogen in 14 (16%) samples, H. influenzae in 15 (17%), M. catarrhalis in 5 (5.6%), T. otitidis in 2, and Staphylococcus auricularis in 2. Weaker signals of Prevotella melaninogenica, Veillonella dispar, and Veillonella montpellierensis were noted in several samples. Fourteen samples (16%) were not explainable by bacterial pathogens; novel causative agents were not detected. In conclusion, unbiased bacteriome profiling helped in depicting the true mutual quantitative ratios of ear bacteria, but at present, its complicated protocol impedes its routine clinical use. IMPORTANCE Although S. pneumoniae, H. influenzae, and M. catarrhalis have been long established as the most important pathogens in acute otitis media using culture and specific PCR assays, the knowledge of their mutual quantitative relations

Inclusion criteria included 3 months (or more) history of OME resistant to medical therapy. Twenty-two control patients (34 ears) underwent cold myringotomies with knife and ventilation tubes (VT). Diode laser myringotomy performed in an office setting under local anesthesia with topical EMLA ointment. Timing of closure of the myringotomy, hearing results, incidence of complications, recurrence of OME. No intra- or postoperative pain nor complications were observed. Otomicroscopic daily monitoring documented the healing patterns of the tympanostomies, which remained patent for 7 to 25 days (average, 15.6 +/- 4.8 days). Immediate improvement of hearing was achieved in every patient. Recurrence of OME was observed in 36 ears (92.3%) within 1 month from healing. In the control group with VTs, healing of the eardrum was observed between 126 and 301 days (average, 183.2 +/- 44.8 days), and recurrence of OME was observed in 8 ears (23.5%) (p < 0.001). One month after healing, the air-bone gap was retained within 10 dB in 10.3% (4/39) of the diode laser group and in 50% (17/34) of the standard procedure group (p=0.0001). Diode laser myringotomy is a straightforward, painless procedure simplified by the thin fiberoptic cables available. Functional benefit is comparable to conventional tympanostomies plus VTs, but the duration of patency is too short to achieve long-term clearance of the effusion in "glue" ears of adult patients. Selected indications could be acute or recurrent otitis media or the prevention of barotraumas in tubal dysfunction.

Chronic suppurative otitis media (CSOM) is a chronic infection of the middle ear cleft. In sub-Saharan Africa >50% of cases occur in children <10 years of age. To describe the otological, audiological and bacteriological findings in children with CSOM. We conducted a prospective study at the Ear, Nose and Throat (ENT) Clinic at Universitas Academic Hospital between August 2009 and December 2010. We included all children with CSOM over this period. Patients underwent ENT and paediatric examination, and were tested for HIV. Pus swabs were taken after an ear toilet for routine microbiology, fungal and Mycobacterium tuberculosis culture. We performed audiological testing after the otorrhoea had resolved. Eighty-six children (113 ears) were included, with a median age of 4.6 years (range 1 - 12 years). The mean duration of otorrhoea was 161.7 weeks (range 4 - 572 weeks). Nine patients (10.5%) presented with coalescent mastoiditis and/or intracranial complications of CSOM. Of the 153 organisms identified; Gram-negative bacteria were present in 93 (82.3%) ears, with 94.8% of these being sensitive to quinolones. Only 1 case of tuberculous otitis media was identified. HIV infection was present in 54.6% of patients tested. There was a hearing loss in 44 (66.7%) of the tested affected ears. There was a long delay between the onset of symptoms and accessing ENT services. Most cases of CSOM were due to quinolone-sensitive Gram-negative aerobes. There was a high prevalence of cholesteatoma, hearing loss and other complications in children in this study.

This study compared the effects of 4 outpatient antibiotic regimens on colonization by penicillin-susceptible and -nonsusceptible pneumococci to assess their relative potential to promote colonization with Streptococcus pneumoniae with reduced susceptibility to penicillin. Children presenting with acute otitis media were randomized to receive amoxicillin, cefprozil, ceftriaxone or azithromycin. Nasopharyngeal specimens were collected on days 0, 3-5, 10-14 and 28-30 and assessed for the presence of S. pneumoniae. At each visit, the proportions of penicillin-susceptible and -nonsusceptible pneumococci were compared among treatment groups. Among 1009 enrollees, the prevalence of colonization by S. pneumoniae at baseline was 23.5%, of which 41.1% were penicillin-nonsusceptible. Colonization by nonsusceptible pneumococci was unaltered during the observation period in all treatment groups, with no detectable differences among groups at each visit. By contrast, there was a substantial reduction in the prevalence of colonization by penicillin-susceptible organisms, most notably in subjects treated with amoxicillin. This resulted in a proportional shift toward resistant organism colonization in all groups, with this shift being significantly more pronounced among amoxicillin recipients than in the other groups at 10-12 days (P < 0.02 for each comparison with amoxicillin). Treatment with amoxicillin for acute otitis media resulted in a larger shift toward nonsusceptible organism colonization among those children still colonized postexposure than did treatment with 3 comparison agents. This phenomenon raises theoretical concerns that at the population level, amoxicillin produces conditions that promote the dissemination of the nonsusceptible phenotype more readily than other outpatient antibiotics. Confirmation of these results requires further study.

To compare the effectiveness of Homeopathy and Conventional therapy in Acute Otitis Media (AOM). A randomized placebo-controlled parallel group pilot study of homeopathic vs conventional treatment for AOM was conducted in Jaipur, India. Patients were randomized by a computer generated random number list to receive either individualized homeopathic medicines in fifty millesimal (LM) potencies, or conventional treatment including analgesics, antipyretics and anti-inflammatory drugs. Patients who did not improve were prescribed antibiotics at the 3rd day. Outcomes were assessed by the Acute Otitis Media-Severity of Symptoms (AOM-SOS) Scale and Tympanic Membrane Examination over 21 days. 81 patients were included, 80 completed follow-up: 41 for conventional and 40 for homeopathic treatment. In the Conventional group, all 40 (100%) patients were cured, in the Homeopathy group, 38 (95%) patients were cured while 02 (5%) patients were lost to the last two follow-up. By the 3rd day of treatment, 4 patients were cured in Homeopathy group but in Conventional group only one patient was cured. In the Conventional group antibiotics were prescribed in 39 (97.5%), no antibiotics were required in the Homeopathy group. 85% of patients were prescribed six homeopathic medicines. Individualized homeopathy is an effective conventional treatment in AOM, there were no significant differences between groups in the main outcome. Symptomatic improvement was quicker in the Homeopathy group, and there was a large difference in antibiotic requirements, favouring homeopathy. Further work on a larger scale should be conducted.

2016-01-01

For considering vaccine-prevention of pneumococcal acute otitis media (PncAOM), relationships between pneumococcal carriage, respiratory infection and PncAOM need to be understood. We analyzed nasopharyngeal samples collected from 329 unvaccinated Finnish children aged 2-24 months at scheduled visits and at visits during respiratory infection in 1994-97. We assessed temporal associations of respiratory infection with pneumococcal acquisition and whether PncAOM hazard depends on the relative timing of acquisition and the infection onset. The data comprised 607 person-years of risk-time for acquisition, 245 person-months of concurrent respiratory infection and carriage, and 119 episodes of PncAOM. The acquisition hazard was 3-fold in the month preceding respiratory sickness (hazard ratio, HR 3.5, 90% credible interval CI 2.9, 4.1) as compared to acquisition in healthy children. Moreover, the PncAOM hazard was markedly higher (HR 3.7, 90% CI 2.4, 5.3) during the first month of carriage acquired around the acute phase of respiratory infection (between 1 month before and 1 week after the sickness onset), as compared to carriage acquired later during sickness. The high proportion (76%) of PncAOM events occurring within 1 month of acquisition was due to frequent acquisition being associated with respiratory infection as well as the susceptibility of such acquisition to cause otitis media.

[The influence of interleukin gene polymorphism on the serum cytokine level in the patients presenting with chonic suppurative otitis media].

Baike, E V; Vitkovsky, Yu A; Dutova, A A

The objective of the present work was to study the influence of allelic variant associations of 1-beta interleukin (C3953T, &511C, T31C), interleukin-6 (C174G), and tumour necrosis factor-alpha (G308A) gene polymorphisms on the serum cytokine level in the patients presenting with chronic suppurative otitis media. A total of 299 patients at the age varying from 16 to 55 years with this condition divided into three groups were examined. Group 1 was comprised of 146 patients suffering from the tubotympanic form of chronic suppurative otitis media (CSOM). Group 2 was composed of 153 patients with epitympanic antral form of this condition. The control group included 183 subjects who have never suffered pathological changes in the middle ear. Human genomic DNA was analyzed with the use of the polymerase chain reaction (PCR). The serum cytokine levels were measured by the solid-state enzyme immunoassay in the beginning and at the end of the treatment period. The study has demonstrated that 56.2% of the healthy residents of the trans-Baikal region had the C/T Il-1b (C3953T) genotype. 79.1% of the patients presenting with the carious carious-destructive form of chronic suppurative otitis media were the heterozygous carriers of the T511C gene of 1-beta interleukin and had the maximally high concentrations of this interleukin in the blood serum. A rise in the production of the pro-inflammatory mediator (IL-6) was found to be related to the severity of the inflammatory process in the middle ear. The TNF-alpha content in the patients with CSOM during the active period of the disease proved to increase by a factor of 6 in comparison with that in the subjects of the control group irrespective of the type of mutation.

Secretory otitis media (SOM) remains a common disease among children. Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM), is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®). After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

2010-10-01

Otitis media is an extremely common pediatric infection and is mostly caused by bacteria that are carried within the nasopharyngeal microbiota. It is clear that most otitis media cases involve simultaneous infection with multiple agents. Chinchillas were infected with nontypeable Haemophilus influenzae, Streptococcus pneumoniae, or a combination of both organisms, and the course of disease was compared. In vitro experiments were also performed to address how coinfection impacts biofilm formation. The incidence of systemic disease was reduced in coinfected animals, compared with those infected with pneumococcus alone. Pneumococci were present within surface-attached biofilms in coinfected animals, and a greater proportion of translucent colony type was observed in the coinfected animals. Because this colony type has been associated with pneumococcal biofilms, the impact of coinfection on pneumococcal biofilm formation was investigated. The results clearly show enhanced biofilm formation in vitro by pneumococci in the presence of H. influenzae. Based on these data, we conclude that coinfection with H. influenzae facilitates pneumococcal biofilm formation and persistence on the middle ear mucosal surface. This enhanced biofilm persistence correlates with delayed emergence of opaque colony variants within the bacterial population and a resulting decrease in systemic infection.

Objectives: The correlation between middle ear pathology and nasal allergy has been debated for almost 30 years. This study aimed to evaluate the relationship between otitis media with effusion (OME) and persistent allergic rhinitis symptoms versus intermittent rhinitis in children. Methods: The study included 100 atopic children (52 boys, 48 girls) aged 5–9 years with otological symptoms who were patients of the University of Siena Hospital, Italy. Ear, nose and throat evaluations, tympanometry, skin prick tests (SPTs), mucociliary transport time (MCTt) and Eustachian tube function tests were performed. Results: The SPTs revealed 50 children sensitised to Dermatophagoides pteronyssinus, 34 to grass pollen and 16 to Parietaria. Of all patients, mild symptoms were intermittent in 19 children and persistent in 18; moderate/severe symptoms were intermittent in 22 and persistent in 41. Tubal dysfunction was present in 25 children, whereas middle ear effusion was present in 45 children undergoing myringotomy. The MCTt was slower in the persistent group (21 ± 2 mins) versus the intermittent group (16 ± 2 mins) with a significant difference (P <0.01). Mean eosinophil cationic protein (ECP) values in the middle ear effusions of children who had undergone myringotomy were 251 ± 175.2 μg/L, and mean ECP blood values were 25.5 ± 16.3 μg/L, with significant differences (P < 0.001). Conclusion: There was a significant association between OME, delayed MCTt, ECP values in middle ear effusion and persistent symptoms of allergic rhinitis. These results suggest a direct involvement of the middle ear mucosa as a target organ in persistent forms. PMID:24516755

Ectopic Mineralization in the Middle Ear and Chronic Otitis Media with Effusion Caused by RPL38 Deficiency in the Tail-short (Ts) Mouse*

Noben-Trauth, Konrad; Latoche, Joseph R.

2011-01-01

Inflammation of the middle ear cavity (otitis media) and the abnormal deposition of bone at the otic capsule are common causes of conductive hearing impairment in children and adults. Although a host of environmental factors can contribute to these conditions, a genetic predisposition has an important role as well. Here, we analyze the Tail-short (Ts) mouse, which harbors a spontaneous semi-dominant mutation that causes skeletal defects and hearing loss. By genetic means, we show that the Ts phenotypes arise from an 18-kb deletion/insertion of the Rpl38 gene, encoding a ribosomal protein of the large subunit. We show that Ts mutants exhibit significantly elevated auditory-brain stem response thresholds and reduced distortion-product otoacoustic emissions, in the presence of normal endocochlear potentials and typical inner ear histology suggestive of a conductive hearing impairment. We locate the cause of the hearing impairment to the middle ear, demonstrating over-ossification at the round window ridge, ectopic deposition of cholesterol crystals in the middle ear cavity, enlarged Eustachian tube, and chronic otitis media with effusion all beginning at around 3 weeks after birth. Using specific antisera, we demonstrate that Rpl38 is an ∼8-kDa protein that is predominantly expressed in mature erythrocytes. Finally, using an Rpl38 cDNA transgene, we rescue the Ts phenotypes. Together, these data present a previously uncharacterized combination of interrelated middle ear pathologies and suggest Rpl38 deficiency as a model to dissect the causative relationships between neo-ossification, cholesterol crystal deposition, and Eustachian tubes in the etiology of otitis media.

2017-05-01

Acute otitis media (AOM) is a common childhood disease, with an enormous economic and healthcare-related burden. Guidelines and consensus papers for AOM diagnosis and management were published in many countries. Our objective was to study the differences and similarities between these protocols in developing and developed countries. The keywords: 'acute otitis media' AND 'children' AND ['treatment' or 'management'] AND ['guideline' or 'consensus'] were used in various electronic databases between 1 January 1989 through 31 December 2015. Overall, 99 sources from 62 countries were retrieved: 53 from 22 developed countries, and 46 from 40 developing countries. Representative guidelines from America (the USA, Argentina), Europe (Italy, Moldova), Africa (South Africa, Tanzania, Ethiopia), Asia (Japan, Afghanistan, Sri Lanka),and Oceania (South Australia, Fiji) were compared. Paediatric societies publish guidelines in most developed countries; in developing countries, the Ministry of Health usually initiates guideline formulation. Most guidelines use the same diagnostic criteria and offer watchful waiting in mild-moderate scenarios. Amoxicillin is the suggested first-line antibiotic, whereas options for second-line and third-line therapies vary. Duration of therapy varies and is usually age dependent: 5-7 days for children <2 years and 10 days for children >2 years in developed countries, while duration and age groups vary greatly in developing countries. Reduction of AOM risk factors is encouraged in developed countries, but rarely in developing countries. Guidelines for AOM from developing and developed countries are similar in many aspects, with variation in specific recommendations, due to local epidemiology and healthcare accessibility. Formulation of regional guidelines may help reduce AOM burden. Published by the BMJ Publishing Group Limited.

Protein D-containing vaccines may decrease acute otitis media (AOM) burden and nasopharyngeal carriage of non-typeable Haemophilus influenzae (NTHi). Protein D-containing pneumococcal conjugate vaccine PHiD-CV (Synflorix, GSK Vaccines) elicits robust immune responses against protein D. However, the phase III Clinical Otitis Media and PneumoniA Study (COMPAS), assessing PHiD-CV efficacy against various pneumococcal diseases, was not powered to demonstrate efficacy against NTHi; only trends of protective efficacy against NTHi AOM in children were shown. Areas covered: This review aims to consider all evidence available to date from pre-clinical and clinical phase III studies together with further evidence emerging from post-marketing studies since PHiD-CV has been introduced into routine clinical practice worldwide, to better describe the clinical utility of protein D in preventing AOM due to NTHi and its impact on NTHi nasopharyngeal carriage. Expert commentary: Protein D is an effective carrier protein in conjugate vaccines and evidence gathered from pre-clinical, clinical and observational studies suggest that it also elicits immune response that can help to reduce the burden of AOM due to NTHi. There remains a need to develop improved vaccines for prevention of NTHi disease, which could be achieved by combining protein D with other antigens.

Background Approximately 75% of children with cleft palate (CP) have Otitis Media with Effusion (OME) histories. Evidence for the effective management of OME in these children is lacking. The inconsistency in outcome measurement in previous studies has led to a call for the development of a Core Outcome Set (COS). Despite the increase in the number of published COS, involvement of patients in the COS development process, and methods to integrate the views of patients and health professionals, to date have been limited. Methods and Findings A list of outcomes measured in previous research was identified through reviewing the literature. Opinion on the importance of each of these outcomes was then sought from key stakeholders: Ear, Nose and Throat (ENT) surgeons, audiologists, cleft surgeons, speech and language therapists, specialist cleft nurses, psychologists, parents and children. The opinion of health professionals was sought in a three round Delphi survey where participants were asked to score each outcome using a bespoke online system. Parents and children were also asked to score outcomes in a survey and provided an in-depth insight into having OME through semi-structured interviews. The results of the Delphi survey, interviews and parent/patient survey were brought together in a final consensus meeting with representation from all stakeholders. A final set of eleven outcomes reached the definition of “consensus in” to form the recommended COS: hearing; chronic otitis media (COM); OME; receptive language skills; speech development; psycho social development; acute otitis media (AOM); cholesteatoma; side effects of treatment; listening skills; otalgia. Conclusions We have produced a recommendation about the outcomes that should be measured, as a minimum, in studies of the management of OME in children with CP. The development process included input from key stakeholders and used novel methodology to integrate the opinion of healthcare professionals

Development of terahertz otoscope for diagnosing otitis media (Conference Presentation)

NASA Astrophysics Data System (ADS)

Jeon, Tae-In; Ji, Young Bin; Bark, Hyeon Sang; Noh, Sam Kyu; Oh, Seung Jae

2017-03-01

A novel terahertz (THz) otoscope is designed and fabricated to help physicians to diagnose otitis media (OM) with both THz diagnostics and conventional optical diagnostics. The inclusion of indium tin oxide (ITO) glass in the THz otoscope allows physicians to diagnose OM with both THz and conventional optical diagnostics. To determine THz diagnostics for OM, we observed reflection signals from samples behind a thin dielectric film and found that the presence of water behind the membrane could be distinguished based on THz pulse shape. We verified the potential of this tool for diagnosing OM using mouse skin tissue and a human tympanic membrane samples prior to clinical application. The presence of water absorbed by the human membrane was easily distinguished based on differences in pulse shapes and peak-to-peak amplitudes of reflected THz pulses. The potential for early OM diagnosis using the THz otoscope was confirmed by alteration of THz pulse depending on water absorption level.

We report 2 cases of tuberculous otitis media that were diagnosed at Stony Brook University Hospital in New York since 1999. Both patients were women, aged 30 and 31 years. One patient had grown up in Russia, the other was a native-born American who had never left the East Coast region of the United States. Both patients had been symptomaticfor many months; one complainedof chronic otorrhea, and the other reported otorrhea, hearing loss, and discomfort. Neither patient responded to medical management, and both ultimately underwent surgery. One was diagnosed after surgical pathology revealed acid-fast bacilli on frozen-section analysis. In the other, pathology revealed chronic inflammation and granulomata, butstains were negative and her diagnosis was delayed for almost 2 years. We also review 9 other cases of tuberculous otitis media in the United States that have been reported in the literature since 1990. Our review suggests that the number of cases is rising in areas where tuberculosis is most common--that is, in major U.S. cities. Although 3 of these 9 cases occurred as reactivation disease in immigrants, most might have occurred as a result of local transmission. Clinicians should maintain a high degree of suspicion for tuberculosis in patients with chronic otitis symptoms, particularly those who are at higher risk of exposure to tuberculosis.

Objectives Debate continues with respect to a “watch and wait” approach versus immediate antibiotic treatment for the initial treatment of acute otitis media. In this double-blind noninferiority trial, we compared clinical improvement rates at 14 days for children (6 months to 5 years of age) with acute otitis media who were randomly assigned to receive amoxicillin or placebo. Methods We enrolled healthy children who presented to clinics or the emergency department with a new episode of acute otitis media during the fall and winter months in Ottawa (from December 1999 to the end of March 2002). The children were randomly assigned to receive amoxicillin (60 mg/kg daily) or placebo for 10 days. Telephone follow-up was performed on each of days 1, 2 and 3 and once between day 10 and day 14. The primary outcome was clinical resolution of symptoms, defined as absence of receipt of an antimicrobial (other than the amoxicillin in the treatment group) at any time during the 14-day period. Secondary outcomes were the presence of pain and fever and the activity level in the first 3 days, recurrence rates, and the presence of middle ear effusion at 1 and 3 months. Results According to clinical scoring, 415 of the 512 children who could be evaluated had moderate disease. At 14 days 84.2% of the children receiving placebo and 92.8% of those receiving amoxicillin had clinical resolution of symptoms (absolute difference –8.6%, 95% confidence interval –14.4% to –3.0%). Children who received placebo had more pain and fever in the first 2 days. There were no statistical differences in adverse events between the 2 groups, nor were there any significant differences in recurrence rates or middle ear effusion at 1 and 3 months. Interpretation Our results did not support the hypothesis that placebo was noninferior to amoxicillin (i.e., that the 14-day cure rates among children with clinically diagnosed acute otitis media would not be substantially worse in the placebo group

American Cocker Spaniels are overrepresented among breeds that require surgery as a treatment of end-stage otitis externa. However, the prevalence of otitis externa (OE) in this breed remains unknown. We reviewed the year 2010 medical records of 55 private veterinary clinics in Finland to determine the prevalence of OE in American Cocker Spaniels compared with English Cocker and English and Welsh Springer Spaniels. An American Cocker Spaniel owner questionnaire was designed to identify potential risk factors for end-stage OE. From the medical records of 98,736 dogs, the prevalence of OE was highest in Welsh Springer Spaniels (149 out of 468, 31.8%, [95% confidence interval 27.6-36.0]), followed by American Cocker (89/329, 27.0%, [22.2-31.7]), English Springer (96/491, 19.6%, [16.1-23.1]) and English Cocker Spaniels (231/1467, 15.7%, [13.8-17.6]). The mean number of OE episodes in ear-diseased dogs and the number of ear surgeries were highest in American Cocker Spaniels. Owner questionnaires were received for 151 American Cocker Spaniels, 85 (56%) of which had suffered from OE. In 47% (40/85) of these dogs, OE occurred without concurrent skin lesions, 46% (33/72) displayed the first signs of OE before 1 year of age. In 24% (20/85) of the dogs, the signs of OE recurred within 1 month or continued despite treatment, 16% (14/85) required surgery (n = 11) or were euthanized (n = 5; 2 of the operated dogs and 3 others) due to severe OE. The onset of OE before the age of 1 year significantly increased the risk (OR 3.8, 95% CI 1.1-13.6) of end-stage OE. The prevalence of OE in American Cocker Spaniels in Finland was higher than previously reported in Cocker Spaniels, but the highest prevalence of OE was found in Welsh Springer Spaniels. Compared to the other Spaniels, OE was more often recurrent and more frequently surgically managed in American Cocker Spaniels. Based on the questionnaire, early onset (<1 year) of OE increased the risk of end-stage OE. In American

Background Otitis media is an extremely common pediatric infection, and is mostly caused by bacteria that are carried within the nasopharyngeal microbiota. It is clear that most otitis media cases involve simultaneous infection with multiple agents. Methods Chinchillas were infected with nontypeable Haemophilus influenzae, Streptococcus pneumoniae, or a combination of both organisms, and the course of disease was compared. In vitro experiments were also performed to address how coinfection impacts biofilm formation. Results The incidence of systemic disease was reduced in coinfected animals as compared to those infected with pneumococcus alone. Pneumococci were present within surface-attached biofilms in coinfected animals, and a greater proportion of translucent colony type was observed in the coinfected animals. As this colony type has been associated with pneumococcal biofilms, the impact of coinfection on pneumococcal biofilm formation was investigated. The results clearly show enhanced biofilm formation in vitro by pneumococci in the presence of H. influenzae. Conclusions Based on these data, we conclude that coinfection with H. influenzae facilitates pneumococcal biofilm formation and persistence on the middle-ear mucosal surface. This enhanced biofilm persistence correlates with delayed emergence of opaque colony variants within the bacterial population, and a resulting decrease in systemic infection. PMID:20715928

Since Chandler's initial report in 1968 on malignant external otitis (MEO), this entity has been recognized in its earlier stages with increasing frequency. As a result of this, the availability of new antimicrobial agents, and the judicious use of surgery, there has been an improvement in the results of therapy. There remains, however, a subgroup of patients who continue to experience a significant mortality from this infection. A review and selected discussion of our experience with MEO from 1976 to 1979 is presented. Six patients have been diagnosed and successfully treated for MEO. They presented with problems ranging from severemore » otalgia to multiple cranial neuropathy. For the most part, therapy consisted of the now standard aminoglycoside and carbenicillin combination. Two of the patients were in the high mortality risk group. One of these patients developed an osteomyelitis which extended across the skull base resulting in bilateral cranial neuropathies. His therapy included surgery as well as long-term (months) outpatient treatment with tobramycin and carbenicillin with an excellent result. The second patient was treated similarly. The efficacy of this approach is discussed as well as the usefulness of radionuclide bone scanning in assessing the course and therapy of patients with MEO.« less

Homeopathic medications as clinical alternatives for symptomatic care of acute otitis media and upper respiratory infections in children.

The public health and individual risks of inappropriate antibiotic prescribing and conventional over-the-counter symptomatic drugs in pediatric treatment of acute otitis media (AOM) and upper respiratory infections (URIs) are significant. Clinical research suggests that over-the-counter homeopathic medicines offer pragmatic treatment alternatives to conventional drugs for symptom relief in children with uncomplicated AOM or URIs. Homeopathy is a controversial but demonstrably safe and effective 200-year-old whole system of complementary and alternative medicine used worldwide. Numerous clinical studies demonstrate that homeopathy accelerates early symptom relief in acute illnesses at much lower risk than conventional drug approaches. Evidence-based advantages for homeopathy include lower antibiotic fill rates during watchful waiting in otitis media, fewer and less serious side effects, absence of drug-drug interactions, and reduced parental sick leave from work. Emerging evidence from basic and preclinical science research counter the skeptics' claims that homeopathic remedies are biologically inert placebos. Consumers already accept and use homeopathic medicines for self care, as evidenced by annual US consumer expenditures of $2.9 billion on homeopathic remedies. Homeopathy appears equivalent to and safer than conventional standard care in comparative effectiveness trials, but additional well-designed efficacy trials are indicated. Nonetheless, the existing research evidence on safety supports pragmatic use of homeopathy in order to "first do no harm" in the early symptom management of otherwise uncomplicated AOM and URIs in children.

The aim of this study was to investigate the transtympanic ventilation time, the healing course of the tympanic membrane, the early and late complications, and the recurrence rate of otitis media with effusion (OME) within 6 months after CO2 laser myringotomy with the CO2 laser otoscope Otoscan. Prospective clinical study. In this study, laser myringotomy was performed with the CO2 laser otoscope Otoscan in a patient population comprising 81 children (159 ears) with a history of otitis media with effusion (OME) associated with adenoidal and sometimes tonsillar hyperplasia. The procedure on the tympanic membrane was accordingly combined with an adenoidectomy, a CO2 laser tonsillotomy, or a tonsillectomy and therefore performed under insufflation anesthesia. In all ears, approximately 2 mm circular perforations were created in the lower anterior quadrants with a power of 12 to 15 W, a pulse duration of 180 msec, and a scanned area of 2.2 mm in diameter. None of the children showed postoperative impairment of cochleovestibular function such as sensorineural hearing loss or nystagmus. Otomicroscopic and videoendoscopic monitoring documented the closure time and healing pattern of tympanic membrane perforations. The mean closure time was found to be 16.35 days (minimum, 8 days; maximum, 34 days). As a rule, an onion-skin-like membrane of keratinized material was seen in the former myringotomy perforations at the time of closure. At the follow-up 6 months later, the condition of the tympanic membrane of 129 ears (81.1%) could be checked by otomicroscopy and videoendoscopy and the hearing ability by audiometry and tympanometry. The CO2 laser myringotomy sites appeared normal and irritation-free. Two of the tympanic membranes examined (1.6%) showed atrophic scar formation, and 1 (0.8%) had a perforation with a diameter of 0.3 mm. The perforation was seen closed in a control otoscopy 15 months postoperatively. OME recurred in 26.3% of the ears seen intraoperatively with

A common acute condition seen by providers in retails clinics is the evaluation and treatment of acute otitis media (AOM) in children younger than age 20. Annual direct treatment costs for AOM were US $5.3 billion in 1998 dollars. Based on the experience of a large retail pharmacy employer, the authors compared AOM episodes in covered dependents younger than age 20 in retail clinic states to those in states without retail clinic access. Relative costs as well as frequency of visits and antibiotic prescriptions were analyzed for both retail clinic-based, and non-retail clinic-based episodes. Rates of AOM episodes were lower in retail clinic than in non-retail clinic states (62.5 vs. 76.9 per 1000 members per year; P < .0001). The average number of visits per episode was similar between retail clinic and non-retail clinic states (1.417 vs. 1.430, respectively; P = 0.657), suggesting that retail clinics do not result in an increase in overall utilization. On a risk-adjusted basis, retail clinic episodes cost approximately $30-$130 less than community episodes, depending on year. In retail clinic states, the antibiotic prescription fill rate was 95.4% for retail clinic episodes and 82.8% for community episodes, consistent with rates in the literature. This study confirms results of earlier studies that retail clinics are a less costly setting than the community for the treatment of episodes of otitis media There also is little evidence that retail clinics lead to duplication of services (patients receiving follow-up care in other settings).

To compare the eustachian tube (ET) angle (ETa) and length (ETl) of ears with and without chronic otitis media (COM), and to determine the relationship between ET anatomy and the development of COM. A retrospective case-control study. The study group comprised 125 patients (age range, 8-79 years; 64 males and 61 females) with 124 normal ears and 126 diseased ears, including ears with chronic suppurative otitis media (CSOM) with central perforation, intratympanic tympanosclerosis (ITTS), cholesteatoma, and a tympanic membrane with retraction pockets (TMRP). ET angle and length were measured using computed tomography employing the multiplanar reconstruction technique. The ETa was significantly more horizontal in diseased versus normal ears of all study groups (P = .030), and there was no group difference in ETl (P = .160). ETl was shorter in CSOM versus ITTS ears and normal ears (P = .007 and P = .003, respectively) and in cholesteatoma versus TMRP ears (P = .014). In the unilateral COM group, there were no significant differences in the ETa or ETl of diseased versus contralateral normal ears (P = .155 and P = .710, respectively). The ETa was significantly more horizontal in childhood-onset diseased versus normal ears (P = .027), and there was no group difference in ETl (P = .732). The ETa (P = .002) and ETl (P < .001) were significantly greater in males than females. A more horizontal ETa and shorter ETl could be contributory (though not significantly) etiological factors in the development of COM. 3b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

The purpose of this study was to evaluate the in vitro activity of an ear rinse containing tromethamine, EDTA, benzyl alcohol and 0.1% ketoconazole in purified water on Malassezia organisms from dogs with otitis externa. Malassezia organisms were collected from ear swab samples from the external ear canal of 19 dogs with otitis externa plus one control strain of Malassezia pachydermatis. Three test solutions were evaluated: ER (EDTA, tromethamine, benzyl alcohol), ER + keto (EDTA, tromethamine, benzyl alcohol, ketoconazole), and H2O (purified water). Ten-millilitre aliquots of each test solution was transferred into 20 tubes and inoculated with one of the isolates (1 tube per isolate: 19 clinical and 1 control strain). Samples were retrieved from each tube at five time points (0, 15, 30, 45 and 60 min), transferred to Petri dishes, mixed with Sabouraud dextrose agar supplemented with 0.5% Tween 80 and incubated. Following incubation, the plates were examined for growth and colonies counted as colony-forming units per millilitre. The data were analysed using a repeated measures analysis, with pair-wise comparisons of solution-time combinations. There was a significant reduction in Malassezia growth in ER + keto at all time points (P < 0.0001) compared to time zero. Neither ER nor H2O had any effect on the growth of Malassezia. ER + keto was significantly more effective in reducing Malassezia growth (P < 0.0001) at all time points compared to both ER and H2O. ER + keto may be useful in the treatment of Malassezia otitis externa. Future studies should be performed to evaluate the in vivo efficacy of ER + keto as treatment for otic infections caused by Malassezia.

Concentrations of cefaclor (CFC) or amoxicillin-clavulanic acid (AMX/CA) in middle-ear fluid collected preserving the stability and clearing the cell contents has been compared to those obtained using the traditional method. Sixty-seven children with effusive otitis media were treated orally with CFC (20 mg/kg of body weight) or AMX/CA (20 mg/kg) (4:1 ratio). The concentrations in cell-free fluid (C−) appear higher than those in the total fluid (C+) (as assayed traditionally). PMID:12937009
