    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.

    Acute otitis media (A.O.M.) occurs mainly in children. The first peak of this disease appears between 6-18 month of life, and the second between 4-7 year of age. The younger age at which the first A.O.M. incidence is noted, the higher probability of its recurrence. In Poland 65% of children up to the 2 year of age suffer from otitis media once, and 30% more than three times. The portal of infection in a.o.m. comprises: (1) Eustachian tube (2) Blood vessels (3) External auditory meatus with perforated tympanic membrane. In ca. 30% of a.o.m. the causative agents are viruses, while in 70% the disease is due to bacteria (Streptococcus pneumoniae in 30-40%, Haemophilus influenzae ca. 20%, Moraxella catarrhalis 10-15%). A.O.M. is diagnosed basing on history, but mainly using otoscopic examination. Regarding different ear anatomy in infants, otoscopic examination may cause many difficulties. In A.O.M. due to possible dehiscence in tegmen tympani or antri may occur meningismus, and dehiscence in the facial nerve canal can occur facial nerve paresis. The treatment of choice is tympanocentesis and administration of amoxycillin in the dose of 40 mg/kg b.w. daily. After recovery, the examination of upper respiratory tract patency should be performed and following that the evaluation of the ear should be continued.

  4. Acute otitis media in adults: many unknowns.

    Science.gov (United States)

    2003-06-01

    (1) Acute otitis media is likely in adults with recent-onset otalgia, fever, and a bulging eardrum on otoscopy. Management is similar to that in children: no antibiotics in the first instance, then amoxicillin later if antibiotic therapy is needed. (2) Otitis media with a perforated eardrum, and evidence of pus must be distinguished from external otitis. In patients with otitis media and a perforated eardrum, the commonest bacterial isolates are staphylococci, pseudomonas and pneumococci. (3) If antibiotics are prescribed the choice of agent is based on individual clinical findings and underlying health status.

  5. Acute otitis media and acute bacterial sinusitis.

    2011-05-01

    Acute otitis media and acute bacterial sinusitis are 2 of the most common indications for antimicrobial agents in children. Together, they are responsible for billions of dollars of health care expenditures. The pathogenesis of the 2 conditions is identical. In the majority of children with each condition, a preceding viral upper respiratory tract infection predisposes to the development of the acute bacterial complication. It has been shown that viral upper respiratory tract infection predisposes to the development of acute otitis media in 37% of cases. Currently, precise microbiologic diagnosis of acute otitis media and acute bacterial sinusitis requires performance of tympanocentesis in the former and sinus aspiration in the latter. The identification of a virus from the nasopharynx in either case does not obviate the need for antimicrobial therapy. Furthermore, nasal and nasopharyngeal swabs are not useful in predicting the results of culture of the middle ear or paranasal sinus. However, it is possible that a combination of information regarding nasopharyngeal colonization with bacteria and infection with specific viruses may inform treatment decisions in the future.

    New guidelines for managing acute otitis media include stricter criteria for properly diagnosing the condition and ensuring an accurate diagnosis before clinicians make treatment decisions. This is key because of the increase in antibiotic-resistant pathogens. This article focuses on how clinicians can use ancillary techniques and technologies to improve diagnostic accuracy for acute otitis media. Techniques include proper cerumen removal, visualizing the tympanic membrane with the correct otoscope, pneumatic otoscopy, using a spectral gradient acoustic reflectometer, and tympanometry.

    1989-02-01

    We studied the association of acute otitis media with different respiratory virus infections in a pediatric department on the basis of epidemics between 1980 and 1985. Altogether 4524 cases of acute otitis media were diagnosed. The diagnosis was confirmed by tympanocentesis in 3332 ears. Respiratory virus infection was diagnosed during the same period in 989 patients by detecting viral antigen in nasopharyngeal mucus. There was a significant correlation between acute otitis media and respiratory virus epidemics, especially respiratory syncytial virus epidemics. There was no significant correlation between outbreaks of other respiratory viruses and acute otitis media. Acute otitis media was diagnosed in 57% of respiratory syncytial virus, 35% of influenza A virus, 33% of parainfluenza type 3 virus, 30% of adenovirus, 28% of parainfluenza type 1 virus, 18% of influenza B virus and 10% of parainfluenza type 2 virus infections. These observations show a clear association of respiratory virus infections with acute otitis media. In this study on hospitalized children Haemophilus influenzae strains were the most common bacteriologic pathogens in middle ear fluid, occurring in 19% of cases. Streptococcus pneumoniae was present in 16% and Branhamella catarrhalis in 7% of cases. There was no association between specific viruses and bacteria observed in this study.

    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.

    In 2004, the Subcommittee on Management of Acute Otitis Media of the American Academy of Pediatrics and American Academy of Family Physicians published evidence-based clinical practice guidelines on the "Diagnosis and Management of Acute Otitis Media." The guidelines included a definition of acute otitis media (AOM) that included three components: 1) a history of acute onset of signs and symptoms; 2) the presence of middle-ear effusion; and 3) signs and symptoms of middle-ear inflammation. An option to observe selected children with AOM for 48 to 72 hours without initial antibiotic therapy was proposed. This option was based on age, severity of illness, and certainty of diagnosis. Despite the changing prevalence of bacterial pathogens and increasing resistance of Streptococcus pneumoniae, amoxicillin remains the first-line antibiotic for initial antibacterial treatment of AOM. The guideline also addresses the management of otalgia, choice of antibiotics after initial treatment failure, and methods for preventing AOM.

    Acute otitis media is frequently encountered by general practitioners and pediatricians. In the neonatal period acute otitis media may present as an isolated local infection or as part of septicemia. Diagnosis of the condition by otoscopy is difficult. Considering the wide spectrum of middle ear disorders (acute otitis media, otitis media with effusion, chronic suppurative otitis media) one can appreciate why opinions on the management of the condition are diverse. This is a review of the literature on clinical presentation, etiology, risk factors, treatment and prevention of acute otitis media in neonatal life.

    Acute otitis media is one of the most common infectious diseases diagnosed in children. Antibiotic treatment use remains controversial. This summary aims to evaluate the effectiveness and safety of antibiotics in children with acute otitis media. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified six systematic reviews including 18 randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded antibiotics reduce pain at 48-72 hours and reduce the risk of tympanic perforations in children with acute otitis media, but they do not reduce late recurrences and increase the risk of side effects (rash, vomiting and diarrhea).

    The aim of the study was to identify microorganisms and antimicrobial susceptibilities of pathogens from middle ear in children with recurrent acute otitis media and acute otitis media. The study comprised 83 children--42 with recurrent acute otitis media and 41 with acute otitis emdia classified for paracentesis. Agar, chocolate, blood and Chapman plates were inoculated for isolation of bacteria. The plates were incubated at 37 degrees C and examined at 24 hours. The susceptibility of bacteria was determined by disk diffusion technique containing concentration gradients for following antibiotics: penicillin, amoxicillin/clavulanate, ampicillin/sulbactam, cefaclor, cefprozil, cefuroxime, erythromycin, azithromycin, clinadamycin and trimethoprim/sulfamethoxazole. 217 organisms from middle ear in children with recurrent acute otitis media and 131 organisms from middle ear in children with acute otitis media were isolated. Most frequent cultured bacteria were: Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis--71.4% in recurrent acute otitis media and 47.3% in acute otitis media. We observed statistically significant (p acute otitis media older than 2 years. The best susceptibility was observed to amoxicillin/clavulanate (79.7% of bacteria in children with recurrent acute otitis media and 83.2% of bacteria in children with acute otitis media). The most of organisms presented resistance to trimethoprim/sulfamethoxazole--65.9% of bacteria in children with recurrent acute otitis media and 62.6% of bacteria in children with acute otitis media. Our investigation showed that resistance to bacteria increase in children with recurrent acute otitis media, most frequent appear in children older than 2 years and depend on number of episodes of acute otitis media and day care.

    Rosenfeld, R M

    2001-04-01

    The observation option for acute otitis media (AOM) refers to deferring antibiotic treatment of selected children for up to 3 days, during which time management is limited to analgesics and symptomatic relief. With appropriate follow-up complications are not increased, and clinical outcomes compare favorably with routine initial antibiotic therapy. Although used commonly in the Netherlands and certain Scandinavian countries, this approach has not gained wide acceptance in Europe and the United States. This article describes an evidence-based toolkit developed by the New York Region Otitis Project for judicious use of the observation option. The toolkit is not intended to endorse the observation option as a preferred method of management, nor is it intended as a rigid practice guideline to supplant clinician judgement. Rather, it presents busy clinicians with the tools needed to implement the observation option in everyday patient care should they so desire.

    Acute otitis media (AOM) is an important reason for medical visits and antibiotic use in children, with possible complications. Pneumococcal conjugate vaccines (PCV) have been developed from 2000, with first the apparition of the 7-valent PCV (PCV7), and from 2013, of the 13-valent PCV (PCV13). First developed to prevent invasive pneumococcal infections, they have been shown to reduce the number of AOM as well. PC13 has allowed to reduce the nasopharyngeal carriage of the majority of pneumococcal serotypes found in AOM, with a reduction of 77% of pneumococcal AOM, according to one study.

    2003-04-01

    Acute otitis media is usually considered a simple bacterial infection that is treated with antibiotics. However, ample evidence derived from studies ranging from animal experiments to extensive clinical trials supports a crucial role for respiratory viruses in the etiology and pathogenesis of acute otitis media. Viral infection of the upper respiratory mucosa initiates the whole cascade of events that finally leads to the development of acute otitis media as a complication. The pathogenesis of acute otitis media involves a complex interplay between viruses, bacteria, and the host's inflammatory response. In a substantial number of children, viruses can be found in the middle-ear fluid either alone or together with bacteria, and recent studies indicate that at least some viruses actively invade the middle ear. Viruses appear to enhance the inflammatory process in the middle ear, and they may significantly impair the resolution of otitis media. Prevention of the predisposing viral infection by vaccination against the major viruses would probably be the most effective way to prevent acute otitis media. Alternatively, early treatment of the viral infection with specific antiviral agents would also be effective in reducing the occurrence of acute otitis media.

    Acute otitis media is one of the most common pediatric illnesses; however, there is considerable controversy in its management. While most cases are treated with antibiotics, there is a growing concern regarding antibiotic overuse and subsequent drug resistance. Researchers in the Netherlands have developed a "watchful waiting" (ie, an observation approach) that has been successful in treating acute otitis media, although it has not gained widespread popularity in the United States. This review will summarize the latest research on diagnosing acute otitis media as well as different treatment regimens, including the efficacy of the watchful-waiting approach.

    The present study was performed to elucidate the clinical outcome, and etiology of acute otitis media (AOM) in children based on virologic and bacteriologic tests. The study group consisted of 120 children aged 6 to 144 months with AOM. Middle ear fluid (MEF) was tested for viral pathogens by reverse transcriptase polymerase chain reaction (RT-PCR) and for bacteria by gram-staining and culture. Clinical response was assessed on day 2 to 4, 11 to 13, 26 to 28. Respiratory viruses were isolated in 39 patients (32.5%). Respiratory syncytial virus (RSV) (46.5%) was the most common virus identified in MEF samples, followed by human rhinovirus (HRV) (25.6%), human coronavirus (HCV) (11.6%), influenza (IV) type A (9.3%), adenovirus type sub type A (AV) (4%), and parainfluenza (PIV) type -3 (2%) by RT-PCR. In total 69 bacterial species were isolated from 65 (54.8%) of 120 patients. Streptococcus pneumoniae (S. pneumoniae) was the most frequently isolated bacteria. Viral RNA was detected in 31 (56.3%) of 55 bacteria-negative specimens and in 8 (12.3%) of 65 bacteria-positive MEF samples. No significant differences were found between children representing viral infection alone, combined viral and bacterial infection, bacterial infection alone, and neither viral nor bacterial infection, regarding clinical cure, relapse and reinfection rates. A significantly higher rate of secretory otitis media (SOM) was observed in alone or combined RSV infection with S. pneumonia or Haemophilus influenzae (H. influenzae) than in other viruses infection. Conclusion. This study provides information about etiologic agents and diagnosis of AOM in Turkish children. The findings highlight the importance of common respiratory viruses and bacterial pathogens, particularly RSV, HRV, S. pneumoniae and H. influenzae, in predisposing to and causing AOM in children.

    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.

  14. Implementing guidelines for the treatment of acute otitis media.

    Science.gov (United States)

    Barenkamp, Stephen J

    2006-01-01

    The recently published Clinical Practice Guideline for the Diagnosis and Management of Acute Otitis Media represents a sincere effort by the AAP andthe AAFP to provide management guidelines for the practitioner based upon the best scientific evidence available. Despite many years of research and hundreds of clinical studies addressing various aspects of the epidemiology, clinical presentation, and treatment of acute otitis media, important questions remain unaddressed or have been addressed in a less than optimal fashion. These gaps in knowledge and deficiencies in several of the studies that formed the scientific basis for the proposed guidelines are the major reasons behind continued disagreement over certain recommendations. Until more comprehensive and careful analyses can be performed, disagreements are likely to persist. Even so, there is general agreement about most of the recommendations made in these guidelines, and these recommendations will provide a very valuable framework for the practicing physician as he or she cares for children with acute otitis media. To briefly review the major points, first is the critical importance of accurately diagnosing acute otitis media using a combination of clinical findings and observable abnormalities of the tympanic membrane and middle ear space. Particularly important is the differentiation of acute otitis media from otitis media with effusion. Second is the value of treating the pain associated with acute otitis media as a regular component of care, irrespective of any decision concerning antimicrobial treatment. Third is the option, for a select group of older patients with nonsevere disease, of withholding antimicrobial therapy for the first 48 to 72 hours, if close follow-up and active parental involvement can be guaranteed. Fourth is the recommendation that if an antimicrobial agent is used, high-dose amoxicillin (80 to 90 mg/kg/d) is the treatment of choice for most children at the time of initial presentation

Patients were diagnosed as suffering from acute otitis media when presented with earache, fever, fullness and or otorrhea. Patients were divided into two equal groups on basis of the treatment they received, Group A received only symptomatic treatment while Group B were given Amoxicillin (40 mg/kg/day) for 7 days. Acute otitis media was common in children under 15 years (64.7%). Patients presented with earache (100%), aural fullness (90.68%), fever (76.47%) associated with recent onset of upper respiratory tract infections (88.23%). In group A, improvement was noticed in 28.43% in 3 days while 35.29% in 7 days. In group B, improvement was noticed in 48.03% in day 3 while 86.27% in day 7. In countries where medical care is scarce, patients lost to follow up, it is wise to treat with simple antibiotics like amoxicillin in adequate dose than to treat only symptomatically. It prevents chronicity, early hearing impairments and reduces antibiotic resistance.

    Acute otitis media (AOM) is a common complication of upper respiratory tract infection whose pathogenesis involves both viruses and bacteria. We examined risks of acute otitis media associated with specific combinations of respiratory viruses and acute otitis media bacterial pathogens. Data were from a prospective study of children ages 6 to 36 months and included viral and bacterial culture and quantitative PCR for respiratory syncytial virus (RSV), human bocavirus, and human metapneumovirus. Repeated-measure logistic regression was used to assess the relationship between specific viruses, bacteria, and the risk of acute otitis media complicating upper respiratory tract infection. In unadjusted analyses of data from 194 children, adenovirus, bocavirus, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis were significantly associated with AOM (P virus loads (≥3.16 × 10(7) copies/ml) experienced increased acute otitis media risk. Higher viral loads of bocavirus and metapneumovirus were not significantly associated with acute otitis media. In adjusted models controlling for the presence of key viruses, bacteria, and acute otitis media risk factors, acute otitis media risk was independently associated with high RSV viral load with Streptococcus pneumoniae (odds ratio [OR], 4.40; 95% confidence interval [CI], 1.90 and 10.19) and Haemophilus influenzae (OR, 2.04; 95% CI, 1.38 and 3.02). The risk was higher for the presence of bocavirus and H. influenzae together (OR, 3.61; 95% CI, 1.90 and 6.86). Acute otitis media risk differs by the specific viruses and bacteria involved. Acute otitis media prevention efforts should consider methods for reducing infections caused by respiratory syncytial virus, bocavirus, and adenovirus in addition to acute otitis media bacterial pathogens.

    There are 2 different kinds of chronic otitis media: Otitis media chronica mesotympanalis and otitis media chronica epitympanalis (cholesteatoma). The incidence of chronic otitis media as reported in literature differs in a wide range. The incidence rates vary between 0.45 and 46%. Both, otitis media chronica mesotympanalis and cholesteatoma, lead to eardrum perforation due to lengthy and recurring inflammations. Furthermore, chronic otitis media is characterized by frequently recurring otorrhea and conductive hearing loss.

    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.

    Acute Otitis Media (AOM) is the most common reason for pediatrician's visits and for antibiotic prescription in childhood. A significant rise in bacterial resistance to antibiotic treatment has been detected in recent years. Accordingly, the attitude towards antibiotic treatment for AOM has been re-evaluated. Due to various difficulties in ear examination, physicians overdiagnosis Otitis Media with Effusion (OME) as AOM, leading to unnecessary prescription of antibiotics. The natural history of AOM shows spontaneous improvement without complications. Studies that have examined antibiotic treatment versus placebo in AOM have shown only minimal advantage for the antibiotic therapy in symptom reduction. Critical appraisal of the literature according to Evidence-based Medicine (EBM) criteria has led to several meta-analyses that showed only a minor advantage for antibiotics over placebo in AOM. In the Netherlands, the approach to AOM is that of delayed prescribing: symptomatic therapy is given for the first 24-72 hours and an antibiotic drug is prescribed only if symptoms persist after this initial period. This review examines the difficulties in reaching an accurate diagnosis of AOM and describes the natural history of AOM and evaluates the studies and meta-analyses comparing antibiotics to placebo. The Dutch approach to AOM will be discussed as an option and a recommended basis for reduction in antibiotic prescriptions for AOM.

    Acute otitis media is a very common disease in children. Most children recover with symptomatic therapy like potent analgesics, but occasionally serious complications occur. We present a 3-year-old girl who suffered from acute otitis media for already 2 weeks and presented with fever, abducens nerve palsy of her left eye and vomiting. She was finally diagnosed with an acute otitis media complicated by a mastoiditis, sinus thrombosis, meningitis and cerebellar empyema. Fusobacterium necrophorum was cultured from cerebrospinal fluid. The girl recovered following appropriate antibiotic and anticoagulation treatment.

    Antibiotic treatment of acute otitis media (AOM) accounts for a significant number of all antibiotic prescriptions each year. In the primary care setting, initial antibiotic selection is rarely based on direct evidence, such as cultures of middle ear fluid. Initial antibiotic therapy by the primary care practitioner involves the evaluation and application of information related to prevalence of infecting organisms; in vitro antibiotic spectrum and penetration into middle ear fluid; initial cure rate, relapse and recurrence rates; and antibiotic cost, safety, and convenience. The influence of these factors on the initial antibiotic choice for AOM is reviewed. Several therapeutic dilemmas confronting the prescriber are discussed and a rational approach to initial antibiotic therapy is presented.

    2007-04-01

    Acute otitis media (AOM) is both a commonly diagnosed condition and a frequent indication for antibiotic use in children. Recent literature suggests that antibiotics are not needed in many children with AOM, as most cases resolve spontaneously without complication. However, a majority of AOM infections in children are still treated with antibiotics. The American Academy of Pediatrics and American Academy of Family Physicians released a guideline for treatment of AOM in children. We review the guideline as well as scientific evidence related to AOM treatment options. We support a set of evidence-based guidelines employing a delayed prescription option for antibiotic therapy in selected children. If used appropriately, these cost-effective guidelines will reduce the amount of antibiotics prescribed, increase parental satisfaction, and may lower rates of antibiotic resistance while producing similar rates of resolution of AOM.

    2012-12-01

    Acute otitis media (AOM) is a polymicrobial disease, which usually occurs as a complication of viral upper respiratory tract infection (URI). While respiratory viruses alone may cause viral AOM, they increase the risk of bacterial middle ear infection and worsen clinical outcomes of bacterial AOM. URI viruses alter Eustachian tube (ET) function via decreased mucociliary action, altered mucus secretion and increased expression of inflammatory mediators among other mechanisms. Transient reduction in protective functions of the ET allows colonizing bacteria of the nasopharynx to ascend into the middle ear and cause AOM. Advances in research help us to better understand the host responses to viral URI, the mechanisms of viral-bacterial interactions in the nasopharynx and the development of AOM. In this review, we present current knowledge regarding viral-bacterial interactions in the pathogenesis and clinical course of AOM. We focus on the common respiratory viruses and their established role in AOM.

    Recently, reduced Nasal nitric oxide (nNO) nNO levels have been reported in children with adenoidal hypertrophy predisposing to chronic nasosinusal inflammation. Given the strict anatomic and physiopathologic link between the nasopharyngeal and middle ear compartments, and considering the high prevalence of otitis prone children among those affected with chronic adenoiditis, we designed a study aimed to test any possible difference in nNO levels between non-allergic children with and without recurrent acute otitis media (RAOM) associated with chronic adenoiditis. The study involved 54 children with RAOM (44.4% males; mean age= 7.5±3.5 years) and 51 children without RAOM (47.4% males; mean age= 7.0±3.8 years). nNO levels were significantly reduced in children with RAOM compared to children without RAOM (676.9±250.7 ppb vs 831.8±320.4 ppb, respectively; p= 0.02). Our results could be related to reduced NO production by the ciliated paranasal, nasopharyngeal and middle ear epithelium and the impaired sinusal ostial and Eustachian tube patency due to chronic inflammation, and seem to confirm the involvement of NO pathway in recurrent upper airway infections related to impaired ciliated respiratory mucosa.

  12. Prevention of acute otitis media using currently available vaccines.

    2012-04-01

    Acute otitis media (AOM) is common in infants and children. Although approximately two-thirds of cases are due to bacteria, almost all of the episodes are preceded by upper respiratory viral infection. Several viruses, among which respiratory syncytial virus is the most common, are involved in the determination of AOM. However, a significant number of AOM cases are associated with influenza infection, and influenza viruses are among the most frequently found respiratory viruses in the middle ear fluid during an acute episode of AOM. Consequently, influenza vaccination may have a favorable impact on the incidence and course of AOM. Moreover, as Streptococcus pneumoniae is one of the leading AOM bacterial pathogens and it is well known that influenza virus infection predisposes to pneumococcal infection, there is a further reason to suggest the use of influenza vaccine to reduce the risk of AOM. On the other hand, the administration of pneumococcal conjugate vaccine is considered per se a possible means of reducing the incidence of the disease. However, although a number of studies have measured the impact of both vaccines on AOM, it is still not known whether (and to what extent) they are really effective, nor what impact the more recently licensed vaccines may have. The aim of this review is to examine the clinical impact of vaccinations on AOM.

    1982-07-01

    We utilized recently developed enzyme immunoassay techniques to examine the role of selected viruses in the etiology of acute otitis media. Viral pathogens were found in middle ear fluids obtained from 13 (24%) of 53 children with acute otitis media; respiratory syncytial virus accounted for ten of the 13 viral agents identified. In addition, respiratory syncytial viral antigen was found in nasopharyngeal washings obtained from 15 of the 53 children. Seven of these children had RSV identified as the sole middle ear pathogen, whereas six children had otitis caused by Streptococcus pneumoniae as either the sole middle ear pathogen or in combination with RSV. Similarly, all three children with respiratory infections caused by influenza virus had ear infections caused by bacterial pathogens, either alone or in combination with influenza virus. These findings suggest that, in patients with viral respiratory infection, coexisting acute otitis media may be associated with the recovery of either viruses or bacteria from the middle ear exudates.

En los pacientes con otitis media recurrente, falla antimicrobiana o cuando se sospeche la presencia de un Streptococcus pneumoniae resistente a la penicilina, se debe considerar el uso de amoxicilina en dosis más elevadas, amoxicilina con ácido clavulánico, macrólidos o ceftrlaxona.Otitis media is one of the most common causes of consultation among the pediatric population. The pathogens most frequently isolated from middle ear fluid are Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis and Streptococcus pyogenes. Antimicrobial resistance patterns vary by region and their knowledge is considered important in order to achieve proper antimicrobial selection. In Costa Rica the microbiology of patients with acute, recurrent and tteattnent failure otitis media has been recently analyzed. The results of these studies indicate that amoxicillin at 50 mg/kg/day for 10 days should be considered first line of therapy for patients with acute otitis media. In patients with recurrent otitis media, therapeutic failures or in patients at risk of having a penicillin non-susceptible Streptococcus pneumoniae, one of the second line agents should be considered.

    Two recent clinical trials have again shown that antibiotics are effective in the management of young children with acute otitis media (AOM). Should this change our reserved attitude towards the use of antibiotics? According to the rules for evidence-based medicine, we cannot ignore the vast body of evidence already existing unless new trials are methodologically better and their results differ from previous trials. This does not seem to be the case. The patient characteristics of these trials are similar to those of a previously published individual patient data meta-analysis. The primary outcome 'symptom scores' reported by Hoberman et al. is also comparable, but Tähtinen et al. may have overestimated the effect of antibiotics. Their primary outcome 'time to treatment failure' does not take later improvement or recovery into account. In both trials, the greatest benefit is related to otoscopic recovery of AOM, which is clinically not the most relevant outcome. For now, there is no reason to adapt the current AOM practice guideline of the Dutch College of General Practitioners.

    The aim of this retrospective study was to determine the possible causes of failure of antibiotic therapy in children with acute otitis media (AOM). Thirty-nine samples of middle-ear fluid were obtained by myringotomy from 31 children suffering from AOM, unrelieved by antibiotic therapy administered for over 48 hours. The samples were analysed by the usual microbiological techniques, including cultures, tests for beta-lactamase producing strains and the determination of the minimal inhibitory concentration of penicillin for Streptococcus pneumoniae. In 14 samples, no bacterial strains were detected in the cultures of middle-ear fluid; and in two samples the cultures revealed two strains of bacteria. The bacteria most frequently identified were Haemophilus influenzae, found in 11 samples, and Streptococcus pneumoniae, found in seven samples, of which four produced strains with reduced susceptibility to penicillin. The failure of antibiotic therapy in AOM appears to be related to the increased resistance of Haemophilus influenzae and to the reduced susceptibility of Streptococcus pneumoniae to penicillin. Other factors contributing to the failure of antibiotic therapy in AOM may be the viruses or the bacteria that produce multiple pathogens in the middle ear.

    This evidence-based clinical practice guideline is a revision of the 2004 acute otitis media (AOM) guideline from the American Academy of Pediatrics (AAP) and American Academy of Family Physicians. It provides recommendations to primary care clinicians for the management of children from 6 months through 12 years of age with uncomplicated AOM. In 2009, the AAP convened a committee composed of primary care physicians and experts in the fields of pediatrics, family practice, otolaryngology, epidemiology, infectious disease, emergency medicine, and guideline methodology. The subcommittee partnered with the Agency for Healthcare Research and Quality and the Southern California Evidence-Based Practice Center to develop a comprehensive review of the new literature related to AOM since the initial evidence report of 2000. The resulting evidence report and other sources of data were used to formulate the practice guideline recommendations. The focus of this practice guideline is the appropriate diagnosis and initial treatment of a child presenting with AOM. The guideline provides a specific, stringent definition of AOM. It addresses pain management, initial observation versus antibiotic treatment, appropriate choices of antibiotic agents, and preventive measures. It also addresses recurrent AOM, which was not included in the 2004 guideline. Decisions were made on the basis of a systematic grading of the quality of evidence and benefit-harm relationships. The practice guideline underwent comprehensive peer review before formal approval by the AAP. This clinical practice guideline is not intended as a sole source of guidance in the management of children with AOM. Rather, it is intended to assist primary care clinicians by providing a framework for clinical decision-making. It is not intended to replace clinical judgment or establish a protocol for all children with this condition. These recommendations may not provide the only appropriate approach to the management of this

Deoxyribonuclease and In-vitro susceptibility of the fungal isolates to Flucytosine (Flu, Nystatin (Nys, Voriconazole (Vor and Ketoconazole (Ket were evaluated using DNase agar and disc diffusion techniques, respectively. The results showed the highest prevalence of AOM in age group ≤ 10 years with 84 (30.9% cases and lowest prevalence in age group ≥ 61 having 12 (4.4% cases. Only 124 (45.6% samples showed positive growth, while 148 (54.4% showed no growth. Of the 124 samples with growth, 9(36.4% samples showed growth of single fungal isolate, while 18 (6.6% and 7 (2.6% showed growth of two and three fungal isolates, respectively. Aspergillus niger was the predominant fungal isolate, followed by Candida albicans with 38 (24.4%, Cryptococcus neoformans 32 (20.5%, Candida spp 21 (13.5% and Aspergillus flavus 14 (9.0%. Only 46 (29.5% of fungal isolates were deoxyribonuclease producers, with 30/38 (78.9% being C. albicans and 16/21 (76.2% being Candida spp. The results of antifungal susceptibility showed that between 65.8 to 71.1% C. albicans, 64.3 to 85.7% A. flavus, 64.7 to 78.4% A. niger, 53.1 to 75.0% C. neoformans, and 52.4 to 57.1% Candida spp. were sensitive to Ket, Vor and Flu, while between 81.6-84.4% of C. albicans and C. neoformans were sensitive to Nys. In overall, 72.4%, 76.3%, 67.9% and 62.2% of the fungal isolates were sensitive to Flu, Nys, Vor and Ket, respectively. Consequently, Nystatin will be highly effective in treating AOM caused by fungi.

    BACKGROUND: Acute otitis media is a common reason for antibiotic prescribing, despite strong evidence that antibiotics provide minimal benefit. Studies have demonstrated that patients' (or parents') expectations of antibiotics often influence general practitioners' (GPs) decision to prescribe...... antibiotics, but few have explored parents' expectations of the management of infections in children, or which factors influence the development of these expectations. This study aimed to explore parents' knowledge and beliefs about the management of acute otitis media in children. METHODS: Individual semi...... experience and the advice of the GP. Pain relief medications, such as paracetamol and non-steroidal anti-inflammatory drugs, were not considered by parents to be sufficient treatment on their own. CONCLUSION: There is discrepancy between parents' beliefs and expectations of management of acute otitis media...

    Antibiotic treatment of acute otitis media is controversial. The questions are when to treat, with which antibiotic, and for how long? Within the last years three reviews attempting to discuss these questions have been published. All three found only a marginal effect of antibiotic treatment. The effect was less earache after the first day. The meta-analyses showed that between eight and 22 children had to be treated before one had any benefit of the treatment. The randomized studies did not find a greater effect of amoxicillin than of penicillin. The marginal effect of antibiotics on acute otitis media supports watchful waiting and individualized care and follow-up. There is a need for well-organized, randomized, placebo-controlled trials including the youngest children and the more severe cases of acute otitis media where the effect of antibiotic treatment may turn out to be most beneficial.

    Some herpesviruses have been detected in middle ear fluid (MEF) of patients with acute otitis media (AOM), but their role in middle ear disease is unknown. We examined 73 middle ear fluid samples from 73 children with acute otitis media for the presence of four major herpesviral DNA, respiratory viral genomes, and bacterial DNA by multiplex polymerase chain reaction (PCR). Herpesviruses were detected in 16 specimens (22%), with 18 viral infections were identified overall. Respiratory viruses were detected in 35 specimens (48%), 39 viral infections overall. Bacterial DNA was detected in 51 specimens (70%), 60 bacterial infections overall. Clinical outcome was compared in patients with and without herpesvirus DNA, respiratory viral genomes, or bacterial DNA. Progression to otitis media with effusion (OME) was more common when herpesviral DNA was present. Presence of herpesvirus DNA may reflect an immunocompromised state that may make it difficult to eliminate bacteria from the middle ear after infection.

    Full Text Available Objective. This study uses the acute otitis media clinical practice guideline proposed in 2004 as a reference to evaluate whether antibiotics doses that are in line with the recommendations lead to better prognosis. The study also attempts to clarify possible factors that influence the outcome. Study Design. Retrospective cohort study. Subjects and Methods. A total of 400 children with acute otitis media were enrolled. The dosage of amoxicillin was considered to be appropriate when in accord with clinical practice guidelines, that is, 80–90 mg/kg/day. The outcome was defined according to the description of tympanic membrane on medical records. Multivariate logistic regression was used to analyze the relationship between antibiotic dosage and prognosis after adjusting for baseline factors. Results. The majority of prescriptions were under dosage (89.1% but it was not noticeably associated with outcome (P= 0.41. The correlation between under dosage and poor prognosis was significant in children below 20 kg with bilateral acute otitis media (odds ratio 1.63; 95% CI 1.02–2.59, P=0.04. Conclusion. Treating acute otitis media in children, high-dose amoxicillin with clavulanate as recommended in the clinical practice guideline was superior to conventional doses only in children under 20 kg with bilateral diseases.

    Nasopharyngeal flora can be a reservoir of bacteria caused acute otitis media in children. The aim of the study was to identify microorganisms and antimicrobial susceptibilities of pathogens from the nasopharynx and middle ear of children with acute otitis media. The study comprised 128 children ages 1 year to 14 years with diagnosed of acute otitis media with purulent discharge. The nasopharyngeal and middle ear samples were collected at the same time. Agar, chocolate, blood and Chapman plates were inoculated for isolation of bacteria. The plates were incubated at 37 degrees C and examined at 24 hours. The susceptibility of bacteria was determined by disk diffusion technique containing concentration gradients for following antibiotics: penicillin, amoxicillin/clavulanate, ampicillin/sulbactam, cefaclor, cefprozil, cefuroxime, erythromycin, azithromycin, clindamycin and trimethoprim/sulfamethoxazole. 196 organisms from nasopharynx and 325 organisms from middle ear were isolated. Most frequent cultured bacteria were: Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis--75.6% in nasopharynx and 77.8% in middle ear. We observed statistically significant (p bacteria from nasopharynx and 81.8% of bacteria from middle ear. Most organisms were resistant to trimethoprim/sulfamethoxazole--60.7% of bacteria from nasopharynx and 62.6% of bacteria from middle ear. Penicillin resistance was observed in 25.0% of bacteria from nasopharynx and 25.6% of bacteria from middle ear. The correlation in resistance of bacteria between trimethoprim/sulfamethoxazole and erythromycin (r = 0.4886) and between trimethoprim/sulfamethoxazole and penicillin (r = 0.5027) was observed. Nasopharyngeal and middle ear flora in children with acute otitis media is similar. In that case susceptibility of bacteria from the nasopharynx can be useful for empirical treatment of acute otitis media in children.

    Full Text Available Abstract Background Acute otitis media with perforation (AOMwiP affects 40% of remote Indigenous children during the first 18 months of life. Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis are the primary bacterial pathogens of otitis media and their loads predict clinical ear state. Our hypothesis is that antecedent respiratory viral infection increases bacterial density and progression to perforation. Methods A total of 366 nasopharyngeal swabs from 114 Indigenous children were retrospectively examined. A panel of 17 respiratory viruses was screened by PCR, and densities of S. pneumoniae, H. influenzae and M. catarrhalis were estimated by quantitative real time PCR. Data are reported by clinical ear state. Results M. catarrhalis (96%, H. influenzae (91%, S. pneumoniae (89% and respiratory viruses (59% were common; including rhinovirus (HRV (38%, polyomavirus (HPyV (14%, adenovirus (HAdV (13%, bocavirus (HBoV (8% and coronavirus (HCoV (4%. Geometric mean bacterial loads were significantly higher in children with acute otitis media (AOM compared to children without evidence of otitis media. Children infected with HAdV were 3 times more likely (p Conclusion This study confirms a positive association between nasopharyngeal bacterial load and clinical ear state, exacerbated by respiratory viruses, in Indigenous children. HAdV was independently associated with acute ear states.

    Non-typeable Haemophilus influenzae (NTHi) is the most common bacteria responsible for episodic acute otitis media (AOM; non-otitis prone), recurrent AOM (rAOM; otitis prone) and AOM treatment failure (AOMTF) in children. In this 3.5 years of prospective study, we measured the serum antibody response to outer membrane proteins D, P6 and OMP26 of NTHi in children with AOM (n=26), rAOM (n=32), AOMTF (n=27). The geometric mean titers (GMTs) of IgG at their acute AOM visit against Protein D in otitis prone children were significantly lower compared to AOMTF (p value4 fold increases in the non-otitis prone children (p value<0.001). We conclude that otitis prone children mount less of an IgG serum antibody response toward Protein D, P6 and OMP26 after AOM which may account for recurrent infections. The data on acute sera of otitis prone vs non-otitis prone children and the acute-to-convalescence response in non-otitis prone children point to a possible link of anti-PD to protection. Moreover, the data suggest that otitis prone children should be evaluated for their responses to Protein D, P6 and OMP26 vaccine antigens of NTHi.

  13. Bacterial Species and Antibiotic Sensitivity in Korean Patients Diagnosed with Acute Otitis Media and Otitis Media with Effusion

    Changes over time in pathogens and their antibiotic sensitivity resulting from the recent overuse and misuse of antibiotics in otitis media (OM) have complicated treatment. This study evaluated changes over 5 years in principal pathogens and their antibiotic sensitivity in patients in Korea diagnosed with acute OM (AOM) and OM with effusion (OME). The study population consisted of 683 patients who visited the outpatient department of otorhinolaryngology in 7 tertiary hospitals in Korea between January 2010 and May 2015 and were diagnosed with acute AOM or OME. Aural discharge or middle ear fluid were collected from patients in the operating room or outpatient department and subjected to tests of bacterial identification and antibiotic sensitivity. The overall bacteria detection rate of AOM was 62.3% and OME was 40.9%. The most frequently isolated Gram-positive bacterial species was coagulase negative Staphylococcus aureus (CNS) followed by methicillin-susceptible S. aureus (MSSA), methicillin-resistant S. aureus (MRSA), and Streptococcus pneumonia (SP), whereas the most frequently isolated Gram-negative bacterium was Pseudomonas aeruginosa (PA). Regardless of OM subtype, ≥ 80% of CNS and MRSA strains were resistant to penicillin (PC) and tetracycline (TC); isolated MRSA strains showed low sensitivity to other antibiotics, with 100% resistant to PC, TC, cefoxitin (CFT), and erythromycin (EM); and isolated PA showed low sensitivity to quinolone antibiotics, including ciprofloxacin (CIP) and levofloxacin (LFX), and to aminoglycosides. Bacterial species and antibiotic sensitivity did not change significantly over 5 years. The rate of detection of MRSA was higher in OME than in previous studies. As bacterial predominance and antibiotic sensitivity could change over time, continuous and periodic surveillance is necessary in guiding appropriate antibacterial therapy. PMID:28244296

    According to studies based on bacterial cultures of middle ear fluids, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis have been the most common pathogens in acute otitis media. However, bacterial culture can be affected by reduced viability or suboptimal growth of bacteria. PCR detects bacterial DNA from samples with greater sensitivity than culture. In the present study, we analyzed the middle ear pathogens with both conventional culture and semiquantitative real-time PCR in 90 middle ear fluid samples obtained from children aged 5 to 42 months during acute otitis media episodes. Samples were tested for the presence of S. pneumoniae, H. influenzae, M. catarrhalis, Alloiococcus otitidis, Staphylococcus aureus, and Pseudomonas aeruginosa One or more bacterial pathogens were detected in 42 (47%) samples with culture and in 69 (77%) samples with PCR. According to PCR analysis, M. catarrhalis results were positive in 42 (47%) samples, H. influenzae in 30 (33%), S. pneumoniae in 27 (30%), A. otitidis in 6 (6.7%), S. aureus in 5 (5.6%), and P. aeruginosa in 1 (1.1%). Multibacterial etiology was seen in 34 (38%) samples, and M. catarrhalis was detected in most (85%) of those cases. Fifteen signals for M. catarrhalis were strong, suggesting a highly probable etiological role of the pathogen. In conclusion, even though M. catarrhalis is often a part of mixed flora in acute otitis media, a considerable proportion of cases may be primarily attributable to this pathogen.

    The objective of the present work was to study the spectrum of bacterial pathogenic agents responsible for the development of acute otitis media under present conditions and to elucidate the relationship between the pathogen species and the clinical course of the inflammatory process in the middle ear. A total of 60 patients of either sex at the age varying from 18 to 64 patients were available for the examination. All of them complained of ear pain, purulent discharge from the ears, hearing impairment, and general weakness. The following methods were employed: the analysis of the patients' complaints and their medical histories, visualexamination of the ENT organs, tonal threshold audiometry, tympanometry, and the analysis of secretion from the tympanic cavity using the real-time PCR technique. The study has demonstrated some regular patterns of the clinical manifestations of the disease depending on its causative agent. Specifically, it turned out that acute otitis media associated with the infection by Streptоcoccus pneumoniae is characterized by the more reactive clinical symptoms and the greater amount of complications compared with acute otitis media caused by Haemophilus influenzae that is largely a subclinical pathology. However, the latter condition more frequently leads to chronization of the pathological process.

    We studied respiratory viruses in 22 children with acute otitis media who had failed to improve after at least 48 hours of antimicrobial therapy. The mean duration of preenrollment antimicrobial therapy was 4.8 days. For comparison we studied 66 children with newly diagnosed acute otitis media. Respiratory viruses were isolated from middle ear fluid or from the nasopharynx, or both, significantly more often in the patients unresponsive to initial antimicrobial therapy than in the comparison patients (68% vs 41%, p less than 0.05). Viruses were recovered from the middle ear fluid in 32% of the study patients and from 15% of the comparison group. Bacteria were isolated from the middle ear fluid of four (18%) children in the study group; one child had an isolate resistant to initial antimicrobial therapy. All four children with bacteria in the middle ear fluid had evidence of concomitant respiratory virus infection. Our results indicate that respiratory virus infection is often present in patients with acute otitis media unresponsive to initial antimicrobial therapy, and may explain the prolongation of symptoms of infection. Resistant bacteria seem to be a less common cause of failure of the initial treatment.

    Full Text Available BACKGROUND: Acute otitis media (AOM is one of the most common forms of bacterial infection and cause for clinic visits in children. The incidence of AOM was 0.9-1.2 episodes per person-year during the first 2 years of life in previous reports conducted before 2000. The aim of this study was to 1 evaluate the latest AOM incidence in pediatric outpatients and 2 identify the bacterial pathogens from these patients and ascertain their serotypes and resistance. METHODS: The study was conducted in a closed population, involving all pediatricians and otolaryngologists in Sado Island allowing accurate determination of AOM incidence. In each month, one week was assigned as "surveillance week", and all outpatients with acute illness aged 0-18 years examined during the surveillance weeks were enrolled. AOM was diagnosed on the basis of otoscopic findings and clinical symptoms were recorded. Specimens were collected from the nasopharynx or middle ear cavity of AOM patients and examined for bacteria. Antimicrobial susceptibilities, serotypes, and molecular typing for resistance were determined among Streptococcus pneumoniae and Haemophilus influenzae. RESULTS: In total, 8,283 clinic visits were conducted, and 354 episodes (4.3%, 95% CI: 3.9-4.7% among 312 children were diagnosed as AOM. The incidence of AOM was highest in children of 1 year of age (0.54 episodes/child/year, 95% CI: 0.44-0.64. Serotype coverage of 7- and 13-valent pneumococcal conjugate vaccines in this study were 38.0% (95% CI: 29.3-47.3 and 62.8% (95% CI: 53.6-71.4, respectively. Of 122 H.influenzae isolates available for typing, 120 were nontypeable and 2 were type b. A high proportion of S. pneumoniae isolates (46% showed resistance to penicillin. Approximately half of H. influenzae isolates had genetic markers for beta-lactamase-negative ampicillin-resistance. CONCLUSIONS: Approximately 4-5% of pediatric outpatients, even without AOM-related symptoms, had AOM in our study. Pediatricians

    Acute Otitis media is one of the most common acute respiratory infections managed in primary care and the most common infection among in children. Diagnostic criteria, however, do not always correspond to scientific evidence. They often differ depending on individual preferences and competences. Treatment, also, is controversial. In Germany, most children attending their pediatrician or primary care physician will be prescribed antibiotics. Evidence from several randomized studies and systematic reviews suggests that routine usage of antibiotics provides only modest benefit. The benefit of prescribing antibiotics should not only be balanced against the increased likelihood of side effects such as diarrhoea but also against the potential to contribute to longterm antibiotic resistance.

    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 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 (pmedia 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.

    Histamine levels were measured in 677 middle ear fluid (MEF) samples from 248 children (aged 2 months to 7 years) with acute otitis media (AOM); of these, 116 (47%) had documented viral infection. Histamine content was higher in bacteria-positive than in bacteria-negative MEF samples (P = .007) and higher in samples from patients with viral infection than in those from patients with no viral infection (P = .002). Bacteria and viruses together had an additive effect on histamine content in MEF. Histamine concentration in the initial MEF sample tended to be higher in patients with persistent otitis than in those with good response to treatment (P = .14). Results suggest that viruses, bacteria, or both induce histamine production, which leads to increased inflammation in the middle ear. Antihistaminic drugs may be beneficial. Large, prospective, controlled trials of the effects of antihistamine as an adjunct therapy in bacterial and viral AOM are required before recommendations can be made.

    Amoxicillin is a first-line antibiotic treatment for acute otitis media in children and one of the most commonly used antibiotics for human bacterial infections. We investigated changes in salivary bacterial communities among children treated with amoxicillin for acute otitis media (n = 18), using a culture-independent approach based on pyrosequencing of the V3 region of the bacterial 16S rRNA gene. The control group consisted of children with acute otitis media who were not given antibiotics (n = 15). One species-level phylotype assigned to the genus Streptococcus was identified across all (n = 99) saliva samples. Two additional species-level phylotypes from the genera Gemella and Granulicatella were shared by all (n = 45) samples of control subjects. Amoxicillin treatment resulted in reduced species richness and diversity, and a significant shift in the relative abundance of 35 taxa at different ranks from phylum to species-level phylotype. At the phylum level, prevalence of TM7 and Actinobacteria decreased at the end of treatment, whereas Proteobacteria had a higher relative abundance post-treatment. Multivariate analysis showed that samples from the same control subject taken over time intervals tended to cluster together. Among antibiotic-treated subjects, samples taken before and at the end of amoxicillin treatment formed two relatively well-separated clusters both of which greatly overlapped with samples taken about 3 weeks post-treatment. Our results point to a substantial but incomplete recovery of the salivary bacterial community from the antibiotic about 3 weeks after the end of treatment.

    Full Text Available Introduction: Xylitol is a sugar naturally found in various vegetables and fruits. Studies have demonstrated that the xylitol can be used as new preventive method for acute otitis media (AOM. Objective: To clarify the possible mechanisms of xylitol actions to inhibit the growth of otopathogenic bacteria and to describe researches that contribute for the discussion about the feasibility of the use of this sugar in the prevention of AOM. Method: Literature review based on scientific articles selected by means of the medical databases: MEDLINE, Cochrane, PubMed (MeSH and Web of Science. Results: Studies have demonstrated the efficacy of xylitol to prevent the AOM, when it is administered five times a day in chewing gum. However, this sugar is not so effective in the prevention of AOM during upper airways infections. Final Comments: Xylitol seems to be an effective strategy in prevention of acute otitis media. However, new studies are necessary to establish ideal doses, frequencies and vehicles for the correct administration of the sugar, which allows for its utilization in the public health system.

    Many children experience recurrent acute otitis media (RAOM) in early childhood. In a previous study, 2-year-old children with RAOM were shown to have immature neural patterns for speech sound discrimination. The present study further investigated the consonant inventories of these same children using natural speech samples. The results showed…

    Full Text Available Abstract 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 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.

    INTRODUCCIÓN: la otitis media aguda es la enfermedad bacteriana más frecuente en los niños menores de cinco años, por lo que constituye una de las causas más comunes de consulta médica pediátrica. El objetivo de esta investigación fue conocer el panorama epidemiológico de la otitis media aguda, con la finalidad de determinar la factibilidad de considerarla un indicador centinela de la atención médica. MÉTODOS: se recolectaron y analizaron todos los casos nuevos de otitis media aguda que se presentaron entre 2008 y 2011. Se determinaron proporciones, razones y tasas de incidencia, y se calcularon los límites para proporciones por prueba exacta de P-media. Resultados: en los niños menores de cinco años de edad se observó 20 % de los casos de otitis media no supurativa y 17 % de los casos de otitis media supurativa. En ese grupo de edad, aumentó la razón de casos de infecciones respiratorias agudas en relación con los de otitis media: 87:1 en 2008 a 53:1 en 2011.

    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.

    The prevalence of otitis media is increasing, which affects health care resource utilization across all segments, including the urgent care setting. One of the greatest challenges in the management of acute otitis media (AOM) is the effective treatment of cases caused by pathogens that are resistant to commonly used antibiotics. Whereas the production of beta-lactamases among strains of Haemophilus influenzae and Moraxella catarrhalis is an important consideration for antimicrobial therapy, the high prevalence of resistance to penicillin and other classes of antibiotics among strains of Streptococcus pneumoniae represents a greater clinical concern. The Centers for Disease Control and Prevention (CDC) recently convened the Drug Resistant S. pneumoniae Therapeutic Working Group to develop evidence-based recommendations for the treatment of AOM in an era of prevalent resistance. The recommendations from this group included amoxicillin as the preferred first-line drug because of the demonstrated activity against penicillin-intermediate and -resistant strains of S. pneumoniae, using higher dosages of up to 90 mg/kg per day in certain settings. For patients in whom initial treatment is unsuccessful after 3 days, the recommended agents included high-dose amoxicillin-clavulanate (for activity against beta-lactamase-producing pathogens), clindamycin, cefuroxime axetil, or 1 to 3 doses of intramuscular ceftriaxone. The principles set forth in these guidelines can assist the therapeutic decisionmaking process for practitioners in the urgent care setting.

    Serum opsonization of yeast (Saccharomyces) was investigated in 51 patients whose ages were between six and 48 months (median 15 months) with acute purulent otitis media and in an age-matched control group (median 13 months). Opsonization was assessed by measuring yeast particle uptake in an assay based on an electronic count of the unphagocytosed particles in serum by polymorphonuclear leukocytes. Despite normal levels of CH50 and serum immunoglobulins, a defective opsonization was determined in 13.7 percent of the patients (7 in 51). The corresponding figure was 2.9 percent in 103 healthy controls (p < 0.001). On the other hand, 218 percent (5 in 23) of the children having a history of recurrent purulent otitis media showed defective opsonization (p < 0.001). Previously, the presence of an opsonization defect has been linked to low levels of mannan binding lectin (MBL), a calcium dependent serum lectin that acts as an opsonin. Therefore, our findings indirectly support the idea that MBL has an important role as host defense, particularly in the earlier period of life when the antibody repertoire is restricted.

    Acute otitis media is one of the most common infections in children and one of the leading causes for antibiotic prescription. In this paper, we assess and comment the Cochrane systematic review 'Antibiotics for acute otitis media in children', which aimed at assessing the efficacy and safety of antibiotics for acute otitis media in children and identifying subgroups of children who might benefit more than others from antibiotic treatment. This review showed spontaneous resolution of acute otitis media in most children (82%) and a favorable but modest effect of antibiotics, namely in pain control (number needed to treat to benefit: 20), reduction of tympanic membrane perforations and reduction of contralateral acute otitis media. Adverse effects such as vomiting, diarrhea or rash were more common in the antibiotic group (number needed to treat to harm: 14). Thus, for most children, an expectant observational approach during 48-72h without immediate antibiotic prescription seems justified. An additional meta-analysis found that antibiotics appear to be most useful in children with both acute otitis media and otorrhoea and children under two years of age with bilateral acute otitis media.

    Recurrent acute otitis media (rAOM) is frequently encountered in infants and children and the lack of any definitive treatment has led parents and physicians to try complementary and alternative therapies. We evaluated the efficacy of a propolis and zinc suspension in preventing AOM in 122 children aged 1-5 years with a documented history of rAOM, who were prospectively, blindly, randomized 1:1 to receive the suspension plus elimination of environmental risk factors or elimination of environmental risk factors only. AOM- and respiratory-related morbidity were assessed at study entry and every four weeks. In the 3-month treatment period AOM was diagnosed in 31 (50.8%) children given the propolis and zinc suspension and in 43 (70.5%) controls (p=0.04). The mean number of episodes of AOM per child/month was 0.23+/-0.26 in the propolis and zinc group and 0.34+/-0.29 in controls (reduction 32.0%, p=0.03). The administration of a propolis and zinc suspension to children with a history of rAOM can significantly reduce the risk of new AOM episodes and AOM-related antibiotic courses, with no problem of safety or tolerability, and with a very good degree of parental satisfaction. No effect can be expected on respiratory infections other than AOM.

    Otitis media typically presents as either acute otitis media (AOM), with symptoms including fever, otalgia, otorrhoea or irritability and short duration; or as otitis media with effusion (OME), which is often asymptomatic and characterised by accumulation of fluid in the middle ear. Diagnostic certainty of otitis media is challenging, given the young age of patients and variability of symptoms. Otitis media predominantly occurs as coincident to viral upper respiratory tract infections and/or bacterial infections. Common viruses that cause upper respiratory tract infection are frequently associated with AOM and new-onset OME. These include respiratory syncytial virus, rhinovirus, adenovirus, parainfluenza and coronavirus. Predominant bacteria that cause otitis media are Streptococcus pneumoniae, Moraxella catarrhalis, and non-typeable Haemophilus influenzae. Antibiotic therapy does not significantly benefit most patients with AOM, but long-term prophylactic antibiotic therapy can reduce the risk of otitis media recurrence among children at high risk. In Australia, 84% of AOM is treated with antibiotic therapy, which contributes to development of antibiotic resistance. Vaccine development is a key future direction for reducing the world burden of otitis media, but requires polymicrobial formulation and ongoing monitoring and modification to ensure sustained reduction in disease burden.

    Otitis represents the second most common infection of the upper respiratory tract, its treatment being the most common cause for prescribing antibiotics in the United States. A large number of antimicrobials, especially beta-lactams and macrolides, are generally used for treating acute otitis media (AOM) in paediatric patients, owing to their antibacterial spectrum including the main aetiological pathogens. Efficacy, safety and compliance of Cefaclor were compared with those of other antibiotics in the treatment of paediatric AOM in a meta-analysis of randomized controlled trials published between 1981 and 2004. Overall, evaluations were performed on 24 studies (Medline/PubMed, keywords "Cefaclor and otitis") which proved eligible (jadad score > or = 1); sixteen out of the 24 studies were multicentre, seven were double-blind. Mostly, the comparator agent was a beta-lactam, in four and three cases it was a macrolide or the association trimethoprim-sulfamethoxazole, respectively. Efficacy and safety were end-points of all studies whereas only 9 studies evaluated compliance. For the majority of studies (16/24) Cefaclor was administered for 10-day course. The analysis was based on a 2 x 2 contingency table with classification by treatment and number of improvements/cures, side-effects, and compliance of individual studies. The global estimate of the effective treatments was obtained with the weighted mean of the log OR (Odd Ratio) according to Mantel-Haenszel and associated confidence intervals (CI) at 95%. All the calculations were performed using SAS v.8. Chi-square test was performed. Clinical efficacy evaluation, number of improvements/cures, did not evidence a statistically significant difference among Cefaclor and comparators (86.8% vs 88.7%; Odds Ratio 0.77, IC 0.61/0.94). In the Cefaclor-treated patients, adverse events were observed in a statistically significant lower percentage compared to other antibiotics: 13.3% vs 19.4% (P antibiotics usually employed in

    Objective. To determine if use of a homeopathic ear drop preparation reduces antibiotic use in children diagnosed with acute otitis media (AOM). Methods. Children 6 months to 11 years old, diagnosed with AOM and managed with a delayed antibiotic approach, were randomized to standard therapy alone or standard therapy plus a homeopathic ear drop preparation. The primary outcome was whether or not the antibiotic prescription given at the index visit was filled during a 12- to 15-day follow-up period. Results. Among 210 enrolled children, follow-up antibiotic data were collected on 206. During the 12- to 15-day follow-up period, fewer parents of children randomized to the homeopathic ear drops group filled the antibiotic prescription compared with those of children receiving standard therapy alone (26.9% and 41.2%, respectively, P = .032). Conclusion. Homeopathic ear drops may be effective in reducing the use of antibiotics in children with AOM managed with a delayed antibiotic approach.

    Otitis media is a major cause of morbidity in 80% of all children less than 3 years of age and often goes undiagnosed in the general population. There is evidence to suggest that the incidence of otitis media is increasing. The major cause of otitis media is infection of the middle ear with microbes from the nasopharynx. The anatomical orientation of the eustachian tube, in association with a number of risk factors, predisposes infants and young children to the infection. Bacteria are responsible for approximately 70% of cases of acute otitis media, with Streptococcus pneumoniae, nontypeable Haemophilus influenzae and Moraxella catarrhalis predominating as the causative agents. The respiratory viruses, respiratory syncytial virus, rhinovirus, parainfluenza and influenza, account for 30% of acute otitis media cases. Over the past decade, there has been a profound increase in the reported resistance to antibiotics, which, with increased disease burden, has focussed attention on vaccine development for otitis media. A polymicrobial formulation containing antigens from all major pathogens would have the greatest potential to deliver a sustained reduction in the disease burden globally. The disappointing outcomes for otitis media seen with the polysaccharide pneumococcal conjugate vaccine have raised major challenges for the vaccination strategy. Clearly, more knowledge is required concerning immune mechanisms in the middle ear, as well as vaccine formulations containing antigens that are more representative of the polymicrobial nature of the disease. Antigens that have been extensively tested in animal models are now available for testing in human subjects.

    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 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).

    We analyzed data from a 14-year longitudinal study of respiratory infections in young children to determine the relative importance of viral respiratory infection and nasopharyngeal colonization with Streptococcus pneumoniae and Haemophilus influenzae as factors influencing the occurrence of acute otitis media with effusion. The incidence of this disorder was increased in children with viral respiratory infections (average relative risk, 3.2; P less than 0.0001). Infection with respiratory syncytial virus, influenza virus (type A or B), and adenovirus conferred a greater risk of otitis media than did infection with parainfluenza virus, enterovirus, or rhinovirus. Colonization of the nasopharynx with Str. pneumoniae or H. influenzae had a lesser effect on the incidence of the disease (average relative risk; 1.5; P less than 0.01). Infections with the viruses more closely associated with acute otitis media (respiratory syncytial virus, adenovirus, and influenza A or B) were correlated with an increased risk of recurrent disease. Prevention of selected otitis-associated viral infections should reduce the incidence of this disease.

So this study was conducted to know the aerobic bacterial pathogens causing OM and their susceptibility pattern in children below 18 years attending a rural tertiary health care center in north Kerala . MATERIALS AND METHODS : A total of 75 patients in pediatric age group 2 months to 18 years clinically havingASOM , were included in the study . Ear discharge was collected using sterile cotton swabs and processed accordingly. RESULTS : A total of 75 patients aged 2 months to 18 years with discharging ears wer e included in the study. Among them , forty one (54.7% were males and thirty four (45.3% were females. Forty five children were below years. Sixty five (86.6% had unilateral ear discharge. Among the 75 ear swabs cultured , 66 (88% had aerobic bacteria is olated. S.aureus was themost common isolate accounting to 32(47% followed by P.aeruoginosa 19(27.9%. It was observed that most of the Staphylococcus aureusisolates were resistant to p en i cillins and first generation cephalosporins while Pseudomonas aerugi nosa to fluoroquinolones. CONCLUSION : Since there is reduced susceptibility of the pathogens isolated to first and second line antibacterials it is necessary to use these antibacterials judiciously and in the right dosage

    Anaerobic bacteria, Peptostrepotococcus intermedius and Propionibacterium acnes, were found in mixed culture specimens from four to ten tested cases of chronic secretory otitis media. These anaerobic bacteria were in a mixed infection flora with aerobic bacteria most often Staphylococcus epidermidis and Cornybacterium sp. which do not fit any established species. The findings of anaerobic bacteria in otitis media is consistent with the sporadic report of the involvement of anaerobic bacteria in otitis media in the literature since 1898.

    Otitis media remains a major health problem in Australia, with an unacceptably great dichotomy of incidence and severity of otitis media and its complications between Indigenous and non-Indigenous Australians. Among most children with acute otitis media, infection resolves rapidly with or without antibiotics, with ongoing middle ear effusion the only sequela. Overcrowding, poor living conditions, exposure to cigarette smoke, and lack of access to medical care are all major risk factors for otitis media. Estimates of the number of cases of otitis media in 2008 vary between 992,000 and 2,430,000 Australians, with a total estimated cost of $100 - $400 million.

    In this evidence-based case report, we studied the clinical question: Is a positive family history of acute otitis media (AOM) predictive for recurrent acute otitis media (rAOM) in children between zero and two years of age? The search yielded 3178 articles, of which only two were relevant and had a high validity regarding our clinical question. Neither of these two studies provided the final answer to our clinical question because they did not report stratified absolute risks for a positive family history. Fortunately, we were able to study the absolute risks in one of the two studies. The absolute risk of rAOM without distinguishing family history was 33 percent; the risk was 27 percent for children without a family history and 45 percent for children with a positive family history. Family history increases the absolute risk, but not in a way that it will help to predict rAOM accurately.

    The introduction of pneumococcal conjugate vaccine may change the epidemiology of Streptococcus pneumoniae. The increased prevalence of non-vaccine serotypes as the cause of pneumococcal diseases has already reported in the United States and Europe. However, little attention has been focused on the S. pneumoniae. In this study, nonencapsulated S. pneumoniae were identified in 15 isolates (6.4%) out of 236 pneumococcal strains obtained from the nasopharynges of children with acute otitis media (AOM), in 3 isolates (14.3%) out of 21 strains from acute rhinosinusitis, and in 2 isolates (12.5%) out of 16 nasopharyngeal carriage strains obtained from normal healthy children. Among the 20 nonencapsulated S. pneumoniae isolates, 15 (75.0%) isolates had the pspK gene. Seven sequence types (STs) were identified: ST7502 (5 strains), ST1106 (2 strains), ST7803 (2 strains), ST7786 (1 strain), ST6741 (1 strain), ST7496 (1 strain), and ST8642 (1 strain). Because nonencapsulated S. pneumoniae strains are not targeted by the current available pneumococcal vaccines, these strains will gradually become more common in nasopharyngeal carriage. The increase in colonization and dissemination of these strains would increase the risk of AOM and other systemic pneumococcal diseases against which current vaccines cannot provide protection. Nonencapsulated S. pneumoniae may thus become more prevalent as human pathogen.

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 h. 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 h 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 2-122 fold higher at 18 h, declining slightly from there at 24 h. 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.

    The use of cochlear implants is increasingly common, particularly in children younger than 3 years. Bacterial meningitis, often with associated acute otitis media, is more common in children with cochlear implants than in groups of control children. Children with profound deafness who are candidates for cochlear implants should receive all age-appropriate doses of pneumococcal conjugate and Haemophilus influenzae type b conjugate vaccines and appropriate annual immunization against influenza. In addition, starting at 24 months of age, a single dose of 23-valent pneumococcal polysaccharide vaccine should be administered. Before implant surgery, primary care providers and cochlear implant teams should ensure that immunizations are up-to-date, preferably with completion of indicated vaccines at least 2 weeks before implant surgery. Imaging of the temporal bone/inner ear should be performed before cochlear implantation in all children with congenital deafness and all patients with profound hearing impairment and a history of bacterial meningitis to identify those with inner-ear malformations/cerebrospinal fluid fistulas or ossification of the cochlea. During the initial months after cochlear implantation, the risk of complications of acute otitis media may be higher than during subsequent time periods. Therefore, it is recommended that acute otitis media diagnosed during the first 2 months after implantation be initially treated with a parenteral antibiotic (eg, ceftriaxone or cefotaxime). Episodes occurring 2 months or longer after implantation can be treated with a trial of an oral antimicrobial agent (eg, amoxicillin or amoxicillin/clavulanate at a dose of approximately 90 mg/kg per day of amoxicillin component), provided the child does not appear toxic and the implant does not have a spacer/positioner, a wedge that rests in the cochlea next to the electrodes present in certain implant models available between 1999 and 2002.

    Full Text Available Introduction Despite the advent of antibiotics and immunizations in the last century, complications of otitis media remain quite frequent, have high morbidity and mortality rates, and pose a challenge to the otorhinolaryngologist. Objective To establish the annual incidence of intratemporal complications of otitis media and prospectively evaluate patients via an analysis of epidemiologic and clinical aspects. Methods Prospective, observational study. Between February 2010 and January 2011, patients admitted to a tertiary care, university-based otology practice with diagnosis of otitis media and an associated intratemporal complication (ITC were included in the study. The following data were evaluated: age, sex, type of ITC, treatment, imaging tests findings, type and degree of hearing loss, and clinical outcome. The overall incidence of all complications and of each complication individually was determined. Results A total of 1,816 patients were diagnosed with otitis media. For 592 (33% individuals, the diagnosis was chronic otitis media; for 1,224 (67%, the diagnosis was acute otitis media. ITCs of otitis media were diagnosed in 15 patients; thus, the annual incidence of intratemporal complications was 0.8%. We identified 19 ITC diagnoses in 15 patients (3 patients had more than one diagnosis. Labyrinthine fistulae were diagnosed in 7 (36.8% individuals, mastoiditis in 5 (26.3%, facial palsy in 4 (21.1%, and labyrinthitis in 3 (15.8%. Conclusion The incidence of intratemporal complications in Brazil remains significant when compared with developed countries. Chronic otitis media with cholesteatoma is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

    Otitis media is the most common reason for children less than 5 years of age to visit a medical practitioner. Whilst the disease rarely results in death, there is significant associated morbidity. The most common complication is loss of hearing at a critical stage of the development of speech, language and cognitive abilities in children. The cause and pathogenesis of otitis media is multifactorial. Among the contributing factors, the single most important are viral and bacterial infections. Infection with respiratory syncytial virus, influenza viruses, para-influenza viruses, enteroviruses and adenovirus are most commonly associated with acute and chronic otitis media. Streptococcus pneumoniae, non-typeable Haemophilus influenzae and Moraxella catarrhalis are the most commonly isolated bacteria from the middle ears of children with otitis media. Treatment of otitis media has largely relied on the administration of antimicrobials and surgical intervention. However, attention has recently focused on the development of a vaccine. For a vaccine to be effective against bacterial otitis media, it must, at the very least, contain antigens that induce a protective immune response in the middle ear against the three most common infecting bacteria. Whilst over the past decade there has been significant progress in the development of vaccines against invasive S. pneumoniae disease, these vaccines are less efficacious for otitis media. The search for candidate vaccine antigens for non-typeable H. influenzae are well advanced whilst less progress has been made for M. catarrhalis. No human studies have been conducted for non-typeable H. influenzae or M. catarrhalis and the concept of a tribacterial vaccine remains to be tested in animal models. Only when vaccine antigens are determined and an understanding of the immune responses induced in the middle ear by infection and immunization is gained will the formulation of a tribacterial vaccine against otitis media be possible.

    The addition of the 7-valent pneumococcal conjugate vaccine (PCV7) to the routine immunization schedule in the United States for infants has produced a much more favorable impact on the incidence of acute otitis media (AOM) than anticipated. Because the serotypes included in PCV7 were those most frequently expressing antibiotic resistance in 2001, predictions were made that up to 98% of pneumococcal AOM episodes would be caused by penicillin susceptible strains. However, recent studies have shown that the benefits of PCV7 are becoming eroded. Replacement serotypes of pneumococci have emerged, expressing polysaccharide capsules different from those included in PCV7, with increasing frequency. These replacement strains are coming to dominate in the nasopharynx and in AOM isolates (and in invasive disease). Expansion in the isolation of serotypes 3, 7F, 15B/C/F, 19A, 22F, 33F, and 38 has been described in various surveillance systems. Pneumococcal strains expressing non-PCV7 capsular serotypes also appear to be rapidly acquiring resistance to penicillin and other antibiotics. Emergence of strains of pneumococci expressing non-PCV7 capsular serotypes is occurring by multiple mechanisms including capsular switching as suggested by molecular epidemiology studies. Expansion of the number of serotypes included in pneumococcal conjugate vaccines is needed to sustain a long-term benefit from immunization against these bacteria.

    Full Text Available Background. Acute otitis media [AOM] may affect the accuracy of tympanic temperature measurements. We aimed to compare tympanic temperature measurements in patients with AOM against control groups, as well as compare the tympanic temperatures with axillary thermometry. Methods. This is a prospective, observational study. Patients from pediatric outpatient and emergency clinics who were diagnosed as single-sided AOM were included consecutively in the study. Normal ears of patients and children having the same age and gender who were not diagnosed as AOM were also studied as controls. Results. In patients with AOM, infected ears had higher temperatures than normal ears with a mean of 0.48±0.01°C. There was no significant difference between the right and left tympanic temperatures in control group. Compared with axillary temperature, the sensitivity of tympanic temperature in the infected ear was 91.7% and the specificity was 74.8%. Conclusion. Comparisons of axillary and tympanic temperatures in children with AOM during the active infection concluded higher tympanic temperatures in infected ears. We suggest that the higher tympanic temperatures, approximately 0.5°C in our study, in infected ears may aid in diagnosis of patients with fever without a source in pediatric clinics.

    Non-typeable Haemophilus influenzae (NTHi) causes acute otitis media (AOM) in young children. In our recent paper in Microbes and Infection we described the transcriptome signature elicited from PBMCs at onset of AOM caused by Streptococcus pneumoniae. In the current study we found very different results with NTHi AOM infections; 5.1% of 29 187 genes were differentially regulated by more than 2-fold at the onset of AOM compared with the pre-infection healthy state in the same children. Among the 1487 transcripts, 100 genes associated with the immune defense response were specifically analyzed. About half of the differentially regulated genes associated with antibacterial activity and the cell-mediated immune response were activated and half were suppressed. The important signatures for NTHi in children suggested that the balance of the immune response was toward suppression. Moreover, 90% of the genes associated with a pro-inflammatory cytokine response were down-regulated. The genes associated with the classic complement pathway were down-regulated, although the alternative complement pathway genes were up-regulated. These results provide the first human transcriptome data identifying gene expression in the immune response to be predominantly down-regulated at the onset of AOM due to NTHi.

    We used a controlled before-and-after design with the aims of reducing both the total consumption of antibiotics and the use of broad-spectrum antibiotics against acute otitis media (AOM), and to study to what extent prescriptions for antibiotics against AOM were dispensed. Information on evidence-based treatment of uncomplicated AOM was provided to doctors and nurses, and written guidelines were implemented. Pamphlets and oral information concerning symptomatic treatment and the limited effect of antibiotic use in AOM were given to parents. Eligible patients were 819 children aged 1-15 y. The proportion of patients receiving a prescription for antibiotics was reduced from 90% at baseline to 74% during the study period. The proportion of prescriptions for penicillin V increased from 72% at baseline to 85% during the study period. There were no significant changes at the control site. The proportion of dispensed prescriptions was 70% both at baseline and during the study period. Educational efforts reduced the total consumption of antibiotics and the use of broad-spectrum antibiotics for AOM in children aged 1-15 y at an emergency call service. Data on antibiotic use in AOM based only on prescribing overestimates the use of antibiotics.

    Acute otitis media (AOM) continues to be a common infection in young children. Milder disease, usually due to viruses or less virulent bacteria, resolves equally quickly with or without antibiotics. A bulging tympanic membrane, especially if yellow or hemorrhagic, has a high sensitivity for AOM that is likely to be bacterial in origin and is a major diagnostic criterion for AOM. Perforation of the tympanic membrane with purulent discharge similarly indicates a bacterial cause. Immediate antibiotic treatment is recommended for children who are highly febrile (≥39°C), moderately to severely systemically ill or who have very severe otalgia, or have already been significantly ill for 48 h. For all other cases, parents can be provided with a prescription for antibiotics to fill if the child does not improve in 48 h or the child can be reassessed if this occurs. Amoxicillin remains the clear drug of choice. Ten days of therapy is appropriate for children <2 years of age, whereas older children can be treated for five days.

  6. Presence of viral nucleic acids in the middle ear: acute otitis media pathogen or bystander?

    Viruses play an important role in acute otitis media (AOM) pathogenesis, and live viruses may cause AOM in the absence of pathogenic bacteria. Detection of AOM pathogens generally relies on bacterial culture of middle ear fluid. When viral culture is used and live viruses are detected in the middle ear fluid of children with AOM, the viruses are generally accepted as AOM pathogens. Because viral culture is not sensitive and does not detect the comprehensive spectrum of respiratory viruses, polymerase chain reaction assays are commonly used to detect viral nucleic acids in the middle ear fluid. Although polymerase chain reaction assays have greatly increased the viral detection rate, new questions arise on the significance of viral nucleic acids detected in the middle ear because nucleic acids of multiple viruses are detected simultaneously, and nucleic acids of specific viruses are detected repeatedly and in a high proportion of asymptomatic children. This article first reviews the role of live viruses in AOM and presents the point-counterpoint arguments on whether viral nucleic acids in the middle ear represent an AOM pathogen or a bystander status. Although there is evidence to support both directions, helpful information for interpretation of the data and future research direction is outlined.

    Acute otitis media (AOM) is an inflammatory response to microbes in the middle ear, sometimes associated with rupture of the tympanic membrane. Human leukocytes produce different patterns of inflammatory mediators in vitro when stimulated with Gram-positive and Gram-negative bacteria, respectively. Here, we investigated the cytokine and prostaglandin E2 (PGE2) responses in middle ear fluids (MEFs) from children with spontaneously perforated AOM, and related the mediator levels to the presence of pathogens detected by culture (live) or PCR (live or dead). Furthermore, the in vivo cytokine pattern was compared with that induced in leukocytes stimulated by dead bacteria in vitro. MEFs with culturable pathogenic bacteria contained more interleukin (IL)-1β (median: 110 μg/L vs. bacteria. Cytokine levels were unrelated to bacterial species and to the presence or absence of virus. Similar levels of TNF and IL-6 as found in the MEFs were obtained by in vitro stimulation of leukocytes, whereas 11 times more IL-1β and 3.5 times more IL-8 were produced in vivo, and 22 times more IL-10 was produced in vitro. Vigorous production of proinflammatory cytokines accompanies AOM with membrane rupture, regardless of the causative agent, but the production seems to cease rapidly once the bacteria are killed and fragmented. IL-6 and PGE2, however, remain after bacterial disintegration, and may play a role in the resolution phase.

Children 6 months to 11 years old, diagnosed with AOM and managed with a delayed antibiotic approach, were randomized to standard therapy alone or standard therapy plus a homeopathic ear drop preparation. The primary outcome was whether or not the antibiotic prescription given at the index visit was filled during a 12- to 15-day follow-up period. Results. Among 210 enrolled children, follow-up antibiotic data were collected on 206. During the 12- to 15-day follow-up period, fewer parents of children randomized to the homeopathic ear drops group filled the antibiotic prescription compared with those of children receiving standard therapy alone (26.9% and 41.2%, respectively, P = .032. Conclusion. Homeopathic ear drops may be effective in reducing the use of antibiotics in children with AOM managed with a delayed antibiotic approach.

    Acute otitis media (AOM), induced by respiratory bacteria, is a significant cause of children seeking medical attention worldwide. Some children are highly prone to AOMs, suffering three to four recurrent infections per year (prone). We previously determined that this population of children could have diminished anti-bacterial immune responses in peripheral blood that could fail to limit bacterial colonization in the nasopharynx (NP). Here, we examined local NP and middle ear (ME) responses and compared them to peripheral blood to examine whether the mucosa responses were similar to the peripheral blood responses. Moreover, we examined differences in effector cytokine responses between these two populations in the NP, ME and blood compartments at the onset of an AOM caused by either Streptococcus pneumoniae or non-typeable Haemophilus influenzae. We found that plasma effector cytokines patterned antigen-recall responses of CD4 T cells, with lower responses detected in prone children. ME cytokine levels did not mirror blood, but were more similar to the NP. Interferon (IFN)-γ and interleukin (IL)-17 in the NP were similar in prone and non-prone children, while IL-2 production was higher in prone children. The immune responses diverged in the mucosal and blood compartments at the onset of a bacterial ME infection, thus highlighting differences between local and systemic immune responses that could co-ordinate anti-bacterial immune responses in young children.

    We determined the cost of care for 2 diagnosis and management approaches for acute otitis media (AOM) among children 6 to 30 months old. A case-control design was used. Cases included 208 children diagnosed with AOM based on a bulging tympanic membrane (TM) and treated with amoxicillin/clavulanate. Controls (5:1 ratio) included 1020 children with AOM diagnosed not requiring bulging of the TM and treated with amoxicillin. Fewer cases (49%) than controls (69%) were diagnosed with AOM (P < .001), fewer were diagnosed with recurrent AOM or AOM treatment failure (0.34 vs 1.6/child; P < .0001), and fewer had insertion of tympanostomy tubes (6.3% vs 14.8%) due to recurrent AOM (P < .0001). The combined direct payments and indirect costs for management of AOM were $539/case versus $1,023/control. Using Rochester NY payments generalized to the US birth cohort, this case diagnosis and treatment strategy could save $1.008 billion per year.

    Conclusion The patients with serous labyrinthitis caused by acute otitis media (AOM) exhibited various patterns of nystagmus in which direction-fixed irritative-type nystagmus was the most common pattern. Differential effects on inner ear function by toxic or inflammatory mediators may be responsible for the various manifestation of nystagmus. Objective This study aimed to investigate nystagmus patterns in patients with serous labyrinthitis, and discuss possible mechanisms. Methods From October 2011 to March 2014, 13 consecutive patients with serous labyrinthitis were included. Eye movements of the patients were serially examined using video-nystagmography, and patterns of nystagmus were investigated. Results The most commonly observed pattern was direction-fixed nystagmus (nine of 13 patients). Of these, eight showed irritative-type, and one showed paretic-type. Direction of nystagmus, although the intensity gradually decreased, was not changed during the course of treatment. One patient showed direction-changing spontaneous nystagmus, which changed into paretic-type direction-fixed nystagmus 1 day after myringotomy. Three patients exhibited persistent direction-changing positional nystagmus in a supine head-roll test. Of them, two showed apogeotropic and one showed geotropic type. In all 13 patients, vertigo and hearing loss were improved after the treatment.

    Full Text Available OBJECTIVE: To report the incidence and recurrence of acute otitis media (AOM in Taiwan's pediatric population. METHODS: Information from children (aged <= 12 years with a diagnosis of AOM was retrieved from the 2006 National Healthcare Insurance claims database. We calculated the cumulative incidence rate and the incidence density rate of recurrent AOM within one year after the initial diagnosis in 2006. We used a multivariate logistic regression model to assess the predictors for recurrence of AOM. RESULTS: The annual incidence rate of AOM was estimated to be 64.5 cases per 1,000 children. The overall one-year cumulative incidence rate of recurrence was 33.1%, and the incidence density rate was 33.5 cases per 100 personyears, with the highest figure (41.2 cases per 100 person-years noted for children aged 0-2 years. Recurrence was significantly associated with age, gender, place of treatment, and physician specialty. CONCLUSION: AOM remains a major threat to children's health in Taiwan. Male children and very young children require more aggressive preventive strategies to reduce the risk of recurrence.

    Human parechoviruses (HPeVs) cause mild upper respiratory infections, gastrointestinal symptoms, central nervous system infections and some studies have linked them with acute otitis media (AOM). The aim of the present study was to study further the role of HPeV infections in AOM by detecting these viruses directly from middle ear fluid (MEF), respiratory and stool samples collected from children during AOM episodes. A total of 91 MEF samples, 98 nasal swab (NS) samples and 92 stool samples were collected during 100 AOM episodes in a total of 87 children aged between five to 42 months. All specimens were analyzed by real time RT-PCR for the presence of HPeV RNA. HPeV infection was diagnosed in 12 (14%) patients. HPeV RNA was detected in altogether 13 samples, including four MEF samples, three NS samples and six stool samples. One patient was positive in both stool and MEF samples. The results suggest that HPeV may play a role in some AOM cases, but it is not a major cause of AOM in children.

  16. Clinical implications of antibiotic resistance for management of acute otitis media.

    Antibiotic resistance to available antimicrobial agents has been constant since the introduction of the sulfonamides in the 1930s. Multidrug-resistant Streptococcus pneumoniae and beta-lactamase-producing Haemophilus influenzae are a concern now because of the importance of these pathogens in infections of the respiratory tract in infants and children. Amoxicillin remains the drug of choice for initial episodes of acute otitis media (AOM) although increase of the dosage schedule to 80 mg/kg/day has been recommended by some investigators. There are 15 additional antimicrobial agents approved by the Food and Drug Administration for the indication of AOM. All approved drugs are clinically effective but some have been suggested to have priority for patients who fail amoxicillin: amoxicillin-clavulanate; an oral cephalosporin such as cefuroxime axetil; and intramuscular ceftriaxone. Management of the child with severe and recurrent disease should include antibiotic prophylaxis but the increased incidence of resistance requires selective use. Prevention of infection may be achieved by innovative techniques for interference with attachment of bacteria to the nasal mucosa such as administration of oligosaccharides in a nasal spray. The currently available polysaccharide pneumococcal vaccines have limited immunogenicity in infants, but the vaccine is useful in children 2 years of age and older who still have recurrent AOM. Children with frequent AOM during the prior respiratory season are candidates also for influenza virus vaccine. If medical management fails to prevent new episodes of AOM in children with severe and recurrent disease, placement of tympanostomy tubes and possible adenoidectomy should be considered.

    Full Text Available BACKGROUND: Vaccines including conserved antigens from Streptococcus pneumoniae and nontypeable Haemophilus influenzae (NTHi have the potential to reduce the burden of acute otitis media. Little is known about the antibody response to such antigens in young children with recurrent acute otitis media, however, it has been suggested antibody production may be impaired in these children. METHODS: We measured serum IgG levels against 4 pneumococcal (PspA1, PspA 2, CbpA and Ply and 3 NTHi (P4, P6 and PD proteins in a cross-sectional study of 172 children under 3 years of age with a history of recurrent acute otitis media (median 7 episodes, requiring ventilation tube insertion and 63 healthy age-matched controls, using a newly developed multiplex bead assay. RESULTS: Children with a history of recurrent acute otitis media had significantly higher geometric mean serum IgG levels against NTHi proteins P4, P6 and PD compared with healthy controls, whereas there was no difference in antibody levels against pneumococcal protein antigens. In both children with and without a history of acute otitis media, antibody levels increased with age and were significantly higher in children colonised with S. pneumoniae or NTHi compared with children that were not colonised. CONCLUSIONS: Proteins from S. pneumoniae and NTHi induce serum IgG in children with a history of acute otitis media. The mechanisms in which proteins induce immunity and potential protection requires further investigation but the dogma of impaired antibody responses in children with recurrent acute otitis media should be reconsidered.

    Full Text Available We propose a novel automated algorithm for classifying diagnostic categories of otitis media: acute otitis media, otitis media with effusion, and no effusion. Acute otitis media represents a bacterial superinfection of the middle ear fluid, while otitis media with effusion represents a sterile effusion that tends to subside spontaneously. Diagnosing children with acute otitis media is difficult, often leading to overprescription of antibiotics as they are beneficial only for children with acute otitis media. This underscores the need for an accurate and automated diagnostic algorithm. To that end, we design a feature set understood by both otoscopists and engineers based on the actual visual cues used by otoscopists; we term this the otitis media vocabulary. We also design a process to combine the vocabulary terms based on the decision process used by otoscopists; we term this the otitis media grammar. The algorithm achieves 89.9% classification accuracy, outperforming both clinicians who did not receive special training and state-of-the-art classifiers.

    Human Bocavirus (HBoV) as a newly discovered parvovirus has been commonly detected in respiratory tract infections. However, its role in acute otitis media (AOM) has not been well studied. We examined HBoV in Japanese children with AOM and evaluated the virus prevalence together with clinical manifestations and bacterial findings. Overall, 222 nasopharyngeal swabs and 176 middle ear fluids (MEF) samples were collected from 222 children with AOM (median age, 19 months) between May 2006 and April 2007. HBoV detection was performed by PCR and bacterial isolation by standard culture methods. HBoV was found in the nasopharyngeal aspirates of 14 children (6.3%) and in the MEF of six children (2.7%). When HBoV detection results were evaluated with clinical characteristics of children, resolution time of AOM was significantly longer (p=0.04), and rate of fever symptom was also higher in HBoV-positive group (p=0.04). Furthermore, we found positive correlation between detection of HBoV and Streptococcus pneumoniae in the MEF (p=0.004). Nevertheless, nasopharyngeal proportion of S. pneumoniae was similar between virus positive and negative groups. Furthermore, S. pneumoniae was detected as a single pathogen in all MEF of HBoV-positive cases but one, while it presents mixed with other pathogenic bacteria in nasopharynx. In conclusion, HBoV may worsen the clinical symptoms and prolong the clinical outcome of AOM in pediatric population. Finally, HBoV may prime the secondary bacterial infection in the middle ear in favor of S. pneumoniae.

    Full Text Available OBJECTIVES: Guidelines to treat acute otitis media (AOM were published in 2004. Initial declines in prescribing were shown, but it's unknown if they were sustained. We examine trends in antibiotic dispensing patterns to treat AOM among a large population of children. We also document trends in antibiotic failure. STUDY DESIGN: Children aged 3 months to 12 years with an AOM diagnosis, enrolled in a commercial claims database between January 1, 2000-December 31, 2011 were included. Pharmacy claims within 7 days of diagnosis were searched for antibiotic prescriptions. Antibiotic failure was defined as a dispensing of a different antibiotic class within 2-18 days after the first prescription. We analyzed trends in antibiotic use and failure by class of antibiotic and year. RESULTS: We identified over 4 million children under 13 years with AOM. The proportion of antibiotic dispensing decreased from 66.0% in 2005 to 51.9% in 2007, after which the instances of dispensing rebounded to pre-guideline levels. However, levels began decreasing again in 2010 and the antibiotic use rate in 2011 was 57.6%. Cephalosporin prescriptions increased by 41.5% over eleven years. Antibiotic failure decreased slightly, and macrolides had the lowest proportion of failures, while all other classes had failure rates around 10%. CONCLUSIONS: In recent years, antibiotic dispensing to treat AOM remains high. In addition, the use of broad-spectrum antibiotics is increasing despite having a high rate of treatment failure. Overprescribing of antibiotics and use of non-penicillin therapy for AOM treatment could lead to the development of antibiotic-resistant infections.

    Objective Antibiotic treatment of acute otitis media (AOM) has been suggested to increase the risk of future AOM episodes by causing unfavorable shifts in microbial flora. Because current evidence on this topic is inconclusive and long-term follow-up data are scarce, we wanted to estimate the effect of antibiotic treatment for a first AOM episode occurring during infancy on AOM recurrences and AOM-related health care utilization later in life. Methods We obtained demographic information and risk factors from data of the Wheezing Illnesses Study Leidsche Rijn, a prospective birth cohort study in which all healthy newborns born in Leidsche Rijn (between 2001 and 2012), The Netherlands, were enrolled. These data were linked to children’s primary care electronic health records up to the age of four. Children with at least one family physician-diagnosed AOM episode before the age of two were included in analyses. The exposure of interest was the prescription of oral antibiotics (yes vs no) for a child’s first AOM episode before the age of two years. Results 848 children were included in analyses and 512 (60%) children were prescribed antibiotics for their first AOM episode. Antibiotic treatment was not associated with an increased risk of total AOM recurrences (adjusted rate ratio: 0.94, 95% CI: 0.78–1.13), recurrent AOM (≥3 episodes in 6 months or ≥4 in one year; adjusted risk ratio: 0.79, 95% CI: 0.57–1.11), or with increased AOM-related health care utilization during children’s first four years of life. Conclusions Oral antibiotic treatment of a first AOM episode occurring during infancy does not affect the number of AOM recurrences and AOM-related health care utilization later in life. This information can be used when weighing the pros and cons of various AOM treatment options. PMID:27632355

    A novel infrared (IR) transparent optical fiber coupled to a hand held otoscope and a radiometer was constructed and used to measure the temperatures of the tympanic membrane (TM) and to distinguish between diseased and healthy middle ears. A greater temperature difference between TM readings was found when Acute Otitis Media (AOM) existed in one of the ears examined. This supports the hypothesis that acute inflammation of the middle ear will result in elevated local temperature when measured in such a way that the reading is taken only from the TM without interference of the external canal. The use of an optical fiber enabled temperature measurements of the TM with high spatial resolution eliminating the external ear canal interference. A small patient population was examined and the initial results were statistically significant. In the hands of the primary care physician, this tool would prevent misdiagnosis of AOM preventing indiscriminate use of antibiotics and avoiding complications by early diagnosis.

    Acute otitis media with effusion (OME) is one of the major causes of antibiotic use, indication for operation and hearing loss in children. In two third of the cases the etiologic agents are bacteria. Nonetheless, increasing numbers of reports have implicated viruses as etiologic agents that may have some effect on prognosis of OME. The aim of this study was to investigate the presence of nucleic acids of respiratory syncytial virus (RSV) type A and B, influenza type A virus, adenovirus, cytomegalovirus (CMV), herpes simplex virus type-1 (HSV-1), and enteroviruses in the middle ear effusion specimens from children with otitis media by TaqMan real-time PCR. As a result, 18 of 30 (60%) OME samples were found positive in terms of viral nucleic acids by real-time PCR. RSV-A was detected in nine samples (30%), CMV in 3 (10%) samples and HSV-1 in 1 (3.3%) sample. In five of the samples two viruses were detected in the same sample (three were positive for adenovirus and RSV-A, and two were positive for CMV and RSV-A). Our data have supported the importance of viruses as etiologic agents of OME. Additionally, it was thought that TaqMan real-time PCR may be used as a reliable and rapid method for the detection of viruses in the middle ear effusion samples.

    After PCV7 implementation, clinical characteristics were investigated in 832 young children with acute otitis media, carrying a single S. pneumoniae or H. influenzae in their nasopharynx. As compared with H. influenzae, S. pneumoniae-associated acute otitis media was less frequently associated with treatment failure (odds ratio = 0.5; 95% confidence interval: 0.36-0.83) and recurrence (odds ratio = 0.4; 95% confidence interval: 0.22-0.75). Post-PCV7 serotype replacement seemed not to affect the acute otitis media characteristics in these children.

    We have recently reported that neutrophils play a pivotal role in innate defense against Streptococcus pneumoniae ( Spn) during mouse acute otitis media (AOM). However, the underlying mechanism remains unclear. By constructing models of pneumococcal AOM in C57BL/6 mice and using a specific inhibitor in vivo, we investigated the role of myeloperoxidase (MPO), one of the most important protein components of neutrophils. Experiment results showed a significant increase in MPO production of the recruited neutrophils in Spn-infected mice. Neutrophils killed Spn in a MPO-dependent manner. MPO facilitated the generation of reactive oxygen species (ROS), and consequently promoted Spn clearance at an early stage and exacerbated tissue damage. Moreover, MPO induced neutrophil apoptosis and necrosis, which, in turn, worsened tissue damage. In summary, our study demonstrates that neutrophil MPO plays a paradoxical role in bacterial clearance and tissue damage in pneumococcal AOM.

    Acute otitis media (AOM) is among the most common pediatric diseases, and the most frequent reason for antibiotic treatment in children. Risk of AOM is dependent on environmental and host factors, as well as a significant genetic component. We identify genome-wide significance at a locus on 6q25.3 (rs2932989, Pmeta=2.15 × 10−09), and show that the associated variants are correlated with the methylation status of the FNDC1 gene (cg05678571, P=1.43 × 10−06), and further show it is an eQTL for FNDC1 (P=9.3 × 10−05). The mouse homologue, Fndc1, is expressed in middle ear tissue and its expression is upregulated upon lipopolysaccharide treatment. In this first GWAS of AOM and the largest OM genetic study to date, we identify the first genome-wide significant locus associated with AOM. PMID:27677580

    The findings of computed tomography (CT) of 89 patients clinically suspected of having otitis media were studied in this work. Such results were compared to clinical diagnosis, otoscopy, surgical findings and previous data. Among the results of our analysis, we studied seven patients with acute otitis media and 83 patients with chronic otitis media. The patients with acute otitis media have undergone CT examinations to evaluate possible spread to central nervous system. The diagnosis of cholesteatoma, its extension and complications were the main indication. for chronic otitis media study. The main findings of the cholesteatomatous otitis were the occupation of the epitympanun, the bony wall destruction and the ossicular chain erosion. The CT demonstrated a great sensibility to diagnose the cholesteatoma. (author) 25 refs., 10 figs.

    About 30 % of young children experience excessive, frequent episodes of middle ear infection and are classified as acute otitis media prone (OP). Streptococcus pneumoniae (Spn) is a predominant otopathogen in OP and non-OP (NOP) children. The pathogenesis of middle ear infection involves otopathogen nasopharyngeal (NP) colonization followed by an upper respiratory viral infection that modifies the NP environment to allow a sufficient inoculum of bacteria to reflux via the Eustachian tube into the middle ear space. Here, we analyzed the NP mucosal repair response between age-matched stringently defined OP (sOP) and NOP children who progressed to middle ear infection caused by Spn. We found lower epidermal growth factor, epidermal growth factor receptor, and angiogenin cytokine concentrations in nasal washes of sOP compared with NOP children. Despite higher expression of TLR2/4 transcript expression in nasal epithelium and in polymorphonuclear cells present in nasal secretions in sOP children, sOP children had lower expression of proinflammatory cytokines such as IL-6 and IL-8 in the NP. Chemotaxis-associated cytokine expression at onset of AOM in sOP children was also lower compared with NOP children, possibly indicating a lower capacity to signal the innate immune system. We conclude that lower epithelial cell repair responses during viral infection in the NP combined with diminished innate inflammatory responses potentiate Spn pathogenesis in the sOP child.

    2016-01-01

    Abstract Objective: 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. Methods: 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. Results: 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 >2500g 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. Conclusions: Otitis media with effusion was found in about one third of children younger than 1 year and was mainly associated with artificial feeding. PMID:26559603

    Full Text Available Introduction. Acute otitis is one of the most common pediatric infectious diseases that requires an accurate diagnosis in order to direct appropriate therapy to reduce the risk of complications. In this study pathogens collected from pediatric patients and their antibiotic susceptibility patterns were evaluated. Methods. Between May 2009 and May 2010, 739 samples (swabs taken from nasopharynx in case of acute otitis media and/or from ears in case of acute external otitis, collected from 680 patients, suffering of otalgia, admitted to the emergency department of our Hospital were studied.The specimens were submitted for routine bacterial cultures and the susceptibility tests were performed according to Clinical Laboratory Standards. Nitrocefin was used to detect ß-lactamase activity. Results. 316 samples (42.8% of 739 were negative, 102 (13.8% were positive for Streptococcus pneumoniae, 97 (13.1% for Moraxella catarrhalis, 68 (9.2% for Haemophilus influenzae, 62 (8.4% for Pseudomonas aeruginosa, 49 (6.6% for Staphylococcus aureus, 36 (4.9% for Streptococcus pyogenes, 5 (0.7% for Gram negative and 4 (0.5% for Candida spp. Antibiotic susceptibility tests showed that amikacin, ceftazidime, ciprofloxacin, imipenem, meropenem and piperacillin/tazobactam were active against all Gram negative strains isolated.We found one strain of MRSA. Of 102 Streptococcus pneumoniae, 5 (4.9% were penicillin resistant and 25 (24.5% were erythromycin resistant, showing the prevalence of constitutive phenotype (80%. All M. catarrhalis strains were ß-lactamase producers while all H. influenzae were ß-lactamase negatives. Conclusions. The prevalent etiological agents in pediatric acute otitis are S. pneumoniae, M. catharralis, and H. influenzae, as reported in literature. In external acute otitis P. aeruginosa prevails in particular in summer.

    Streptococcus pneumoniae and Haemophilus influenzae are the major etiologic agents of acute otitis media. This study was aimed to compare the detection rate of S.pneumoniae and H.influenzae by culture and real-time polymerase chain reaction (Rt-PCR) in the middle ear effusions of patients diagnosed as acute otitis media. A total of 60 middle ear effusion samples collected from children with acute otitis media were included in the study. The samples were inoculated and incubated in BACTEC Ped Plus blood culture bottles and BACTEC 9120 system (BD Diagnostic Systems, MD), respectively, and the isolates were identified by conventional methods. For the molecular diagnosis of H.influenzae and S.pneumoniae, ply pneumolysin gene and HIB capsule region, respectively were amplified by Rt-PCR (LightCycler, Roche Diagnostics, Germany). H.influenzae and S.pneumoniae were isolated from 5 (8.3%) and 3 (5%) of the patient samples with conventional culture methods, respectively. In addition in 11.6% of the samples other microorganisms (Staphylococcus epidermidis, Streptococcus intermedius, Streptococcus sanguinis, Moraxella catarrhalis, Pseudomonas aeruginosa, Candida albicans) were also isolated. On the other hand H.influenzae and S.pneumoniae were detected in 38 (63.3%) and 24 (40%) of the samples with Rt-PCR, respectively. There was about eight fold increase in the detection frequency of H.influenzae and S.pneumoniae with Rt-PCR compared to culture methods. When culture was accepted as the gold standard method, the sensitivity, specificity and positive predictive value of Rt-PCR in the detection of H.influenzae and S.pneumoniae were estimated as 80%, 51% and 98.2%, respectively. As a result, Rt-PCR was shown to be a sensitive method and could be preferred for the rapid diagnosis of H.influenzae and S.pneumoniae in the etiological diagnosis of acute otitis media, especially in culture negative cases.

    As infection with Streptococcus pneumoniae (mainly via the mucosal route) is a leading cause of acute otitis media, sinus and bacterial pneumonia, the mucosal immunity plays an important role in the prevention of pneumococcal diseases. Therefore, intranasal vaccination may be an effective immunization strategy, but requires appropriate mucosal vaccine delivery systems. In this work, chitosan was used as a mucosal delivery system to form chitosan-PsaA nanoparticles based on ionotropic gelation methods and used to immunize BALB/c mice intranasally. Compared to mice immunized with naked PsaA, levels of IFN-γ, IL-17A and IL-4 in spleen lymphocytes, the systemic (IgG in serum) and mucosal (IgA in mucosal lavage) specific antibodies were enhanced significantly in mice inoculated with chitosan-PsaA. Furthermore, increased protection against acute otitis media following middle ear challenge with pneumococcus serotype 14, and improved survival following intraperitoneal challenge with pneumococcus serotype 3 or serotype 14, was found in the mice immunized with chitosan-PsaA nanoparticles. Thus, intranasal immunization with chitosan-PsaA can successfully induce mucosal and systemic immune responses and increase protection against pneumococcal acute otitis media and invasive infections. Hence, intranasal immunization with PsaA protein, based on chitosan as a delivery system, is an efficient immunization strategy for preventing pneumococcal infections.

    Full Text Available ABSTRACT: Tuberculous otitis media is a ra re disease that is clinically variable and nonspecific. Tuberculous otitis media can be difficult to diagnose because it can easily be confused with other acute or chronic middle ear conditions. The signs and symptoms are variable and nonspecific and ofte n differ from classic descriptions. Furthermore, no two cases may not necessarily present itself clinically in the same manner. Cases of chronic otitis media that are unresponsive to the usual therapy or show unexpected postoperative evolution should be in vestigated for tuberculosis. Tuberculous otitis media should be suspected after failure of current antibiotics or persistent effusion after tympanoplasty or mastoidectomy. Because of these factors, the diagnosis is often made during surgery or postoperati vely. Late diagnosis delays the start of treatment, thereby increasing the risk of complications

Although effective treatments are available, some shortcomings remain, and thus better treatments would be welcome. Recent discoveries within the field of otitis media research relating to its etiology and pathogenesis have led to further investigation aimed at developing novel treatments. This article provides a review of the latest evidence relating to the understanding of acute otitis media and otitis media with effusion, current treatment strategies, their limitations, new areas of research, and novel strategies for treatment.Keywords: otitis media, ear, hearing, infection, biofilm, antibiotics

    We studied the effect of concomitant nasopharyngeal carriage of beta-lactamase producing Moraxella catarrhalis and Haemophilus influenzae on the occurrence of penicillin resistance of Streptococcus pneumoniae. We took nasopharyngeal samples from 306 children with recurrent otitis media and a history of several antibiotic treatments. We could isolate at least one of the pathogens in 89 subjects. Of these children 13% carried more than one pathogen. Of the isolated M. catarrhalis and H. influenzae strains 93% and 43% produced beta-lactamase, respectively. Of the S. pneumoniae strains 25% were non-susceptible (I/R) to penicillin. However, in patients carrying beta-lactamase-producing M. catarrhalis together with pneumococci all strains were susceptible to penicillin (P=0.0353). This finding suggests that beta-lactamase producing M. catarrhalis may hinder the emergence of penicillin resistance of S. pneumoniae in children with recurrent acute otitis media.

    Full Text Available Introduction & Objective: Acute otitis media (AOM is the most common causes of acquired hearing loss in children with increasing incidence. In young children the diagnosis is restricted to otoscopy and tympanometry whereas evaluation of the auditory function is impossible due to noncompliance during pure tone audiometry. For this purpose, measurement of otoacoustic emissions, especially transient evoked ones (TEOAEs, can be applied. The aim of this study was to evaluate the effect of AOM on TEOAEs in young children before and after treatment course.Material & Methods: In an analytic, cross-sectional design, 42 young children with AOM, both sexes, aged 2 to 4.5 years were evaluated through tympanometry and transient otoacoustic emissions (TEOAEs. TEOAEs signal to noise ratio (SNR and reproducibility of AOM patients were compared before, two weeks and six weeks after the treatment course. Then AOM responses were compared with an age-matched control group. The results were analyzed using SPSS 16.Results: Our findings revealed that TEOAE parameters in AOM subjects were the most affected on highest frequencies. Significant changes of TEOAE parameters were found 2 weeks after the treatment with further improvement 6 weeks after the treatment course (P 0.05.Conclusion: The results of this study suggest that there was an improvement in TEOAE SNR and band reproducibility in serial TEOAEs measurements. Thus,application of TEOAEs is a beneficial method to follow up medical treatment in young children with AOM. (Sci J Hamadan Univ Med Sci 2011;18(3:17-21

    We hypothesized that low-intensity focused ultrasound (LIFU) increases vessel permeability and antibacterial drug activity in the mouse middle ear. We determined appropriate settings by applying LIFU to mouse ears with the external auditory canal filled with normal saline and performed histologic and immunohistologic examination. Acute otitis media was induced in mice with nontypable Haemophilus influenzae, and they were given ampicillin (50, 10, or 2 mg/kg) intraperitoneally once daily for 3 days with or without LIFU (1.0 W/cm(2), 20% duty cycle, 30 s). In the LIFU(+) groups receiving the 2- and 10-mg/kg doses, viable bacteria counts, number of inflammatory cells and IL-1β and TNF-α levels in middle ear effusion were significantly lower than in the LIFU(-) groups on the same doses. Severity of AOM also tended to be reduced more in the LIFU(+) groups than in the LIFU(-) groups. LIFU application with antibiotics may be effective for middle ear infection.

    The aim of this study was to predict the clinical efficacy of different antimicrobials in the treatment of patients with acute otitis media (AOM), before and after the change in the proportion of middle ear pathogens observed after the introduction of the new conjugated heptavalent penumococcal vaccine (pPCV-7). The therapeutic Outcomes model was used to predict the likelihood of clinical success. According to this mathematical model the obtained rank order of predicted clinical efficacy was similar in the pre-PVC7 period and the post-PVC period. The results suggest that ceftriaxone and amoxicillin/clavulanate are the antibiotics with the highest predicted clinical efficacy, whereas cefaclor, azithromycin, erythromycin and clarithromycin are those with the lowest predicted clinical efficacy. The differences between antibiotics with good and those with low antibacterial activity were greater when only cases of bacterial AOM were considered. Antibiotics for which the highest clinical efficacy was predicted should maximize the likelihood of cure in outpatient antibiotic treatment of AOM.

  9. Have Guidelines Affected Ear, Nose, and Throat Specialists’ Diagnoses and the Prescription of Antibiotics for Acute Otitis Media?

    2011-01-01

    Full Text Available Introduction: The Ministry of Health and Medical Education of Iran, and similar institutions in many other countries, advises physicians to use current guidelines for the diagnosis and treatment of acute otitis media (AOM. However, there has been no evaluation of the effectiveness of such guidelines or whether physicians in Iran adhere to them. Thus, as laryngologists are the most important group of people who interact with patients with AOM, the aim of this study was to evaluate the attitude of laryngologists to the established guidelines.  Materials and Methods: A total of 120 anonymous surveys were mailed to 120 otolaryngologists in Tehran, Iran, to evaluate the patterns of diagnosis and treatment of AOM used by these physicians. The survey included questions regarding the otolaryngologists’ age, gender, place of work, and attitude towards diagnosis and treatment of AOM.  Results: Sixty-two completed surveys were received, for a response rate of 51%. There was no significant difference between respondents to these surveys according to sex, age, practice setting, graduation year, or the number of patients with AOM seen each month.  Conclusion: Our study adds new insights to the previous literature on the use of guidelines in the management of AOM. We can now assess the impact of guidelines on the usual practice of physicians in evidenced-based management of AOM.

    Both bacteria and viruses play a role in the development of acute otitis media, however, the importance of specific viruses is unclear. In this study molecular methods were used to determine the presence of nucleic acids of human rhinoviruses (HRV; types A, B, and C), respiratory syncytial viruses (RSV; types A and B), bocavirus (HBoV), adenovirus, enterovirus, coronaviruses (229E, HKU1, NL63, and OC43), influenza viruses (types A, B, and C), parainfluenza viruses (types 1, 2, 3, 4A, and 4B), human metapneumovirus, and polyomaviruses (KI and WU) in the nasopharynx of children between 6 and 36 months of age either with (n = 180) or without (n = 66) a history of recurrent acute otitis media and in 238 middle ear effusion samples collected from 143 children with recurrent acute otitis media. The co-detection of these viruses with Streptococcus pneumoniae, nontypeable Haemophilus influenzae, and Moraxella catarrhalis was analyzed. HRV (58.3% vs. 42.4%), HBoV (52.2% vs. 19.7%), polyomaviruses (36.1% vs. 15.2%), parainfluenza viruses (29.4% vs. 9.1%), adenovirus (25.0% vs. 6.1%), and RSV (27.8% vs. 9.1%) were detected significantly more often in the nasopharynx of children with a history of recurrent acute otitis media compared to healthy children. HRV was predominant in the middle ear and detected in middle ear effusion of 46% of children. Since respiratory viruses were detected frequently in the nasopharynx of both children with and without a history of recurrent acute otitis media, the etiological role of specific viruses in recurrent acute otitis media remains uncertain, however, anti-viral therapies may be beneficial in future treatment and prevention strategies for acute otitis media.

    A total of 3,340 infants, 95 per cent of them 7 to 9 months old, were randomly vaccinated in a double-blind fashion with either the 14-valent pneumococcal (Pn) polysaccharide vaccine or a saline placebo in three urban areas in Finland. The second dose of the vaccine was given 5 months later. Age and sex distribution, recruitment of infants, and their otitis-related treatment and follow-up were similar in the study areas. Side effects after vaccination were mild and fewer than among older children. Antibody responses to vaccine polysaccharides varied from type to type, but were generally poor, especially to types most prevalent in otitis media. After the first dose of vaccine, the occurrence of otitis visits among the Pn-vaccinated, as compared with controls, showed inter-area differences, but ranged from not more than a 30 per cent reduction at its best to an increase in some areas and in some clinical categories. The respective figures for children with acute otitis media were similar between the vaccination groups and the study areas. The effect of the vaccine on acute otitis media caused by specific Pn types/groups represented in the vaccine was variable but generally poor. Group 6 attacks especially seemed to behave problematically. The second dose of the vaccine did not give additional benefit serologically or clinically. The efficacy of currently available pneumococcal vaccine against otitis media seemed poor in infants.

  12. Acute otitis externa: an update.

    2012-12-01

    Acute otitis externa is a common condition involving inflammation of the ear canal. The acute form is caused primarily by bacterial infection, with Pseudomonas aeruginosa and Staphylococcus aureus the most common pathogens. Acute otitis externa presents with the rapid onset of ear canal inflammation, resulting in otalgia, itching, canal edema, canal erythema, and otorrhea, and often occurs following swimming or minor trauma from inappropriate cleaning. Tenderness with movement of the tragus or pinna is a classic finding. Topical antimicrobials or antibiotics such as acetic acid, aminoglycosides, polymyxin B, and quinolones are the treatment of choice in uncomplicated cases. These agents come in preparations with or without topical corticosteroids; the addition of corticosteroids may help resolve symptoms more quickly. However, there is no good evidence that any one antimicrobial or antibiotic preparation is clinically superior to another. The choice of treatment is based on a number of factors, including tympanic membrane status, adverse effect profiles, adherence issues, and cost. Neomycin/polymyxin B/hydrocortisone preparations are a reasonable first-line therapy when the tympanic membrane is intact. Oral antibiotics are reserved for cases in which the infection has spread beyond the ear canal or in patients at risk of a rapidly progressing infection. Chronic otitis externa is often caused by allergies or underlying inflammatory dermatologic conditions, and is treated by addressing the underlying causes.

    Full Text Available Abstract Background For children at high risk of chronic suppurative otitis media (CSOM, strategies to prevent acute otitis media with perforation (AOMwiP may reduce progression to CSOM. Methods In a double blind study in northern Australia, 103 Aboriginal infants with first detection of OME were randomised to receive either amoxicillin (50 mg/kg/d BD or placebo for 24 weeks, or until bilateral aerated middle ears were diagnosed at two successive monthly examinations (success. Standardised clinical assessments and international standards for microbiology were used. Results Five of 52 infants in the amoxicillin group and none of 51 infants in the placebo group achieved success at the end of therapy (Risk Difference = 9.6% [95% confidence interval 1.6,17.6]. Amoxicillin significantly reduced the proportion of children with i perforation at the end of therapy (27% to 12% RD = -16% [-31,-1], ii recurrent perforation during therapy (18% to 4% RD = -14% [-25,-2], and iii reduced the proportion of examinations with a diagnosis of perforation during therapy (20% to 8% adjusted risk ratio 0.36 [0.15,0.83] p = 0.017. During therapy, the proportion of examinations with penicillin non-susceptible (MIC > 0.1 microg/ml pneumococci was not significantly different between the amoxicillin group (34% and the placebo group (40%. Beta-lactamase positive non-capsular H. influenzae (NCHi were uncommon during therapy but more frequent in the amoxicillin group (10% than placebo (5%. Conclusion Aboriginal infants receiving continuous amoxicillin had more normal ears, fewer perforations, and less pneumococcal carriage. There was no statistically significant increase in resistant pneumococci or NCHi in amoxicillin children compared to placebo children who received regular paediatric care and antibiotic treatment for symptomatic illnesses.

    Full Text Available Abstract Background Non-typeable Haemophilus influenzae (NTHi and Streptococcus pneumoniae are major causes of bacterial acute otitis media (AOM. Data regarding AOM are limited in Latin America. This is the first active surveillance in a private setting in Venezuela to characterize the bacterial etiology of AOM in children Methods Between December 2008 and December 2009, 91 AOM episodes (including sporadic, recurrent and treatment failures were studied in 87 children enrolled into a medical center in Caracas, Venezuela. Middle ear fluid samples were collected either by tympanocentesis or spontaneous otorrhea swab sampling method. Standard laboratory and microbiological techniques were used to identify bacteria and test for antimicrobial resistance. The results were interpreted according to Clinical Laboratory Standards Institute (CLSI 2009 for non-meningitis isolates. All statistical analyses were performed using SAS 9.1 and Microsoft Excel (for graphical purposes. Results Overall, bacteria were cultured from 69.2% (63 of the 91 episodes; at least one pathogen (S. pneumoniae, H. influenzae, S. pyogenes or M. catarrhalis was cultured from 65.9% (60/91 of episodes. H. influenzae (55.5%; 35/63 episodes and S. pneumoniae (34.9%; 22/63 episodes were the most frequently reported bacteria. Among H. influenzae isolates, 62.9% (22/35 episodes were non-capsulated (NTHi and 31.4% (11/35 episodes were capsulated including types d, a, c and f, across all age groups. Low antibiotic resistance for H. influenzae was observed to amoxicillin/ampicillin (5.7%; 2/35 samples. NTHi was isolated in four of the six H. influenzae positive samples (66.7% from recurrent episodes. Conclusions We found H. influenzae and S. pneumoniae to be the main pathogens causing AOM in Venezuela. Pneumococcal conjugate vaccines with efficacy against these bacterial pathogens may have the potential to maximize protection against AOM.

    Full Text Available Abstract Background It is unclear why some children with acute otitis media (AOM have poor outcomes. Our aim was to describe the clinical course of AOM and the associated bacterial nasopharyngeal colonisation in a high-risk population of Australian Aboriginal children. Methods We examined Aboriginal children younger than eight years who had a clinical diagnosis of AOM. Pneumatic otoscopy and video-otoscopy of the tympanic membrane (TM and tympanometry was done every weekday if possible. We followed children for either two weeks (AOM without perforation, or three weeks (AOM with perforation, or for longer periods if the infection persisted. Nasopharyngeal swabs were taken at study entry and then weekly. Results We enrolled 31 children and conducted a total of 219 assessments. Most children had bulging of the TM or recent middle ear discharge at diagnosis. Persistent signs of suppurative OM (without ear pain were present in most children 7 days (23/30, 77%, and 14 days (20/26, 77% later. Episodes of AOM did not usually have a sudden onset or short duration. Six of the 14 children with fresh discharge in their ear canal had an intact or functionally intact TM. Perforation size generally remained very small (Streptococcus pneumoniae (82%, Haemophilus influenzae (71%, and Moraxella catarrhalis (95%; 63% of swabs cultured all three pathogens. Conclusion In this high-risk population, AOM was generally painless and persistent. These infections were associated with persistent bacterial colonisation of the nasopharynx and any benefits of antibiotics were modest at best. Systematic follow up with careful examination and review of treatment are required and clinical resolution cannot be assumed.

    Full Text Available Abstract Background Eustachian tube (ET dysfunction plays an important role in the pathogenesis of acute otitis media (AOM. Unfortunately, there is a lack of knowledge about the exact role of the ET’s bony support, the temporal bone, on occurrence of AOM. This study investigates whether severe suture restriction of the temporal bone is a risk factor for development of AOM in young children. Methods Using a prospective cohort design, 64 children aged 6 to 18 months without prior history of AOM were followed during the cold season (September 2009 to April 2010. Temporal bone status (categorized as with or without severe suture restriction was evaluated using palpation and a cranial bone mobility test. Information about potential baseline confounders and risk factors for AOM (gender, age, birth weight, gestational age, use of pacifier, daycare attendance, presence of siblings, low socioeconomic status, breastfeeding ≥ 6 months, parental smoking and history of upper respiratory tract infection were also collected. Occurrence of AOM diagnosed by physicians blinded to temporal bone status was the main outcome. Data were analyzed using hierarchical linear and nonlinear (multilevel models. Results Severe suture restriction of the temporal bone was identified in 23 children (35.9%. At least one AOM episode was diagnosed in 14 (48.3% of the ears associated with temporal bones previously identified as having severe suture restriction and in 28 (28.3% of those without severe suture restriction. Higher risk for AOM was explained by severe suture restriction of the temporal bone (adjusted relative risk (RR, 2.26, 95% CI 1.43 to 2.91, p Conclusions The study results indicate that severe suture restriction of the temporal bone is a risk factor for AOM in young children. Subsequent intervention studies are needed to determine if this mechanical risk factor can be modified in young children.

    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.

    Full Text Available : INTRODUCTION: Tuberculous otitis media is a rare cause of chronic suppurative infection of the middle ear and mastoid. The incidence of tuberculosis in the middle ear is very low and accounts for only 0.04% of all cases of chronic Suppurative otitis media. Its diagnosis is often delayed because it can easily be confused with other acute or chronic middle ear conditions, still the treatment of tuberculous otitis media is medical treatment with anti -tuberculous drugs and mastoid exploration if the temporal bone is involved and also to clear the disease from the middle ear cavity to avoid further complications. CASE PRESENTATION: A 21 year male patient presented with ear discharge, deafness and headache, diagnosed as primary tuberculous otitis media, treated with mastoidectomy and anti-tuberculous treatment. DISCUSSION: Primary tuberculous otitis media is very rare condition in adults, it is commonly seen in children which is also secondary to pulmonary tuberculosis / extra pulmonary tuberculosis the treatment of choice is anti tuberculous treatment for 06 months, surgery indicated to clear the disease from middle ear, temporal bone and to avoid further complications. CONCLUSION: Even though primary tuberculosis in middle ear and mastoid is very rare, the diagnosis is possible only with histological findings. In our case there was no signs of pulmonary / extra pulmonary tuberculosis, treated with mastoidectomy followed by anti - tuberculous treatment.

    Full Text Available The prevalence of penicillin non-susceptible Streptococcus pneumoniae (PNSSP is increasing among isolates from acute otitis media (AOM. Repeated episodes of antibiotic exposure are a well-known risk factor for the isolation of PNSSP although otitis-prone or recurrent AOM cases frequently require repeated courses of antibiotic treatment. In order to evaluate the chronological alteration of S. pneumoniae during recurrences of AOM, strains of S. pneumoniae were isolated from 11 patients, each of whom had experienced 2-4 episodes of AOM, were examined. Every bacterial specimen obtained from a single episode of recurrent AOM was examined by PCR-based penicillin-binding protein (PBP assay, serotyping, and amplified fragment length polymorphism (AFLP, then compared to other samples from the same case. Two cases (18.2% showed strain diversity during repeated antibiotic treatments by serotyping or PBP-assay. By AFLP analysis, 6 cases (54.5% demonstrated heterogeneous strains during recurrent AOM. Clonal survivors of previous episodes of AOM were not always the cause of subsequent episodes of AOM, even in otitis-prone cases.

    Full Text Available Abstract Background Several studies have investigated the impact of 7-valent pneumococcal conjugate vaccine (PCV7 on pneumococcal (Sp and staphylococcal (Sa nasopharyngeal (NP carriage. Few have investigated the impact on Haemophilus influenzae (Hi and Moraxella catarrhalis (Mc carriage. We aimed to compare the NP carriage rates in young children with acute otitis media (AOM before and after PCV7 implementation in France. Methods Prior to PCV7 implementation, we performed 4 successive randomized trials with NP samples. These studies compared several antibiotic regimens for treating AOM in young children (6 to 30 months. After PCV7 implementation, to assess the impact of the vaccination program on NP flora, young children with AOM were enrolled in a prospective surveillance study. In each study, we obtained an NP sample to analyze the carriage rates of Sp, Hi, Mc and Sa and the factors influencing the carriage. Standardized history and physical examination findings were recorded; the methods used for NP swabs (sampling and cultures were the same in all studies. Results We enrolled 4,405 children (mean age 13.9 months, median 12.8. Among the 2,598 children enrolled after PCV7 implementation, 98.3% were vaccinated with PCV7. In comparing the pre- and post-PCV7 periods, we found a slight but non-significant decrease in carriage rates of pneumococcus (AOR = 0.85 [0.69;1.05], H. influenzae (AOR = 0.89 [0.73;1.09] and S. aureus (AOR = 0.92 [0.70;1.19]. By contrast, the carriage rate of M. catarrhalis increased slightly but not significantly between the 2 periods (AOR = 1.08 [0.95;1.2]. Among Sp carriers, the proportion of PCV7 vaccine types decreased from 66.6% to 10.7% (P Conclusion The carriage rates of otopathogen species (Sp, Hi, Mc and Sa did not significantly change in children with AOM after PCV7 implementation in France. However, we observed significant changes in carriage rates of PCV7 vaccine serotypes and penicillin non-susceptible Sp.

    Full Text Available Abstract Background The incidence of acute otitis media (AOM vary from country to country. Geographical variations together with differences in study designs, reporting and settings play a role. We assessed the incidence of AOM in Italian children seen by primary care paediatricians (PCPs, and described the methods used to diagnose the disease. Methods This secondary data analysis from the Pedianet database considered children aged 0 – 6 years between 01/2003 and 12/2007. The AOM episodes were identified and validated by means of patient diaries. Incidence rates/100 person-years (PY were calculated for total AOM and for single or recurrent AOM. Results The 92,373 children (52.1% males were followed up for a total of 227,361 PY: 23,039 (24.9% presented 38,241 episodes of AOM (94.6% single episodes and 5.4% recurrent episodes. The total incidence rate of AOM in the 5-year period was 16.8 episodes per 100 PY (95% CI: 16.7-16.9, including single AOM (15.9 episodes per 100 PY; 95% CI: 15.7-16.1 and recurrent AOM (0.9 episodes per 100 PY; 95% CI: 0.9-0.9. There was a slight and continuously negative trend decrease over time (annual percent change −4.6%; 95%CI: -5.3, -3.9%. The AOM incidence rate varied with age, peaking in children aged 3 to 4 years (22.2 episodes per 100 PY; 95% CI 21.8-22.7. The vast majority of the AOM episodes (36,842/38,241, 96.3% were diagnosed using a static otoscope; a pneumatic otoscope was used in only 3.7%. Conclusions Our data fill a gap in our knowledge of the incidence of AOM in Italy, and indicate that AOM represents a considerable burden for the Italian PCP system. Educational programmes concerning the diagnosis of AOM are needed, as are further studies to monitor the incidence in relation to the introduction of wider pneumococcal conjugate vaccines.

    Ruth B Thornton

    Full Text Available BACKGROUND: Bacteria persist within biofilms on the middle ear mucosa of children with recurrent and chronic otitis media however the mechanisms by which these develop remain to be elucidated. Biopsies can be difficult to obtain from children and their small size limits analysis. METHODS: In this study we aimed to investigate biofilm presence in middle ear effusion (MEE from children with recurrent acute otitis media (rAOM and to determine if these may represent infectious reservoirs similarly to those on the mucosa. We examined this through culture, viability staining and fluorescent in situ hybridisation (FISH to determine bacterial species present. Most MEEs had live bacteria present using viability staining (32/36 and all effusions had bacteria present using the universal FISH probe (26/26. Of these, 70% contained 2 or more otopathogenic species. Extensive DNA stranding was also present. This DNA was largely host derived, representing neutrophil extracellular traps (NETs within which live bacteria in biofilm formations were present. When treated with the recombinant human deoxyribonuclease 1, Dornase alfa, these strands were observed to fragment. CONCLUSIONS: Bacterial biofilms, composed of multiple live otopathogenic species can be demonstrated in the MEEs of children with rAOM and that these contain extensive DNA stranding from NETs. The NETs contribute to the viscosity of the effusion, potentially contributing to its failure to clear as well as biofilm development. Our data indicates that Dornase alfa can fragment these strands and may play a role in future chronic OM treatment.

    We report the imaging features of three cases of tuberculous otitis media. All three patients underwent temporal bone CT scanning, and in two, additional MRI scanning was performed. The three cases showed soft tissue density in the external auditory canal, and in two, destruction of the trabeculation and internal cortex of the mastoid bone was noted. In two patients with facial palsy, erosion of the facial canal was seen. On MRI, abundant granulomatous tissue was noted in the middle ear cavity and mastoid air cells. In one case, abnormal enhancement of the cochlea, and of the facial and eighth cranial nerve in the internal acoustic canal was seen. Another case showed enhancement of the vestibule and lateral semicircular canal. If radiologic evaluation of chronic otitis media reveals destruction of the tegmen and trabeculation of the mastoid bone, together with abundant granulation tissue and enhancement of the internal ear, tuberculous otitis media may be included in the differential diagnosis.

    Full Text Available Background: Otitis media is a common inflammatory disorder caused by the effusion of fluids or pathological changes in the tympanic membrane of middle ear that leads to hearing loss in all age groups which may be either temporary or permanent. Objective: The present study aimed to identify the risk factors responsible for the onset and progression of otitis media and its subtypes as well as its associated co-morbidities in the South Indian population. Subjects and methods: The study constituted 2602 subjects including children and adults affected with OM and the diagnosis was confirmed by ENT specialists using all the required otorhinolaryngological tests. The study was carried out by the institutional ethical clearance. The data were coded and evaluations were performed using the Statistical Package for Social Sciences, PASW STATISTICS 18.0 software (SPSS Inc., Chicago, IL, USA. Results: squamous-chronic suppurative otitis media was highly prevalent (47.3% followed by mucosal-chronic suppurative otitis media (18.5%, acute suppurative otitis media (17.6%, and otitis media with effusion (16.6%. The multinomial logistic regression analysis showed significant association of tinnitus with squamous-chronic suppurative otitis media; bilaterality, tinnitus and vertigo with mucosal-chronic suppurative otitis media while bilaterality, adenoids, tinnitus and snoring with otitis media with effusion. Significant differences were observed in different forms of hearing loss at higher frequency within the subtypes of otitis media. Conclusions: The study has revealed that otitis media predominantly affects all age groups and has a serious health concern in cases affected with hearing loss and its associated co-morbidities.

    Nontypeable Haemophilus influenzae (NTHi) makes the clinical course of acute otitis media (AOM) intractable by forming a biofilm that may hamper the clearance of the bacteria from middle ear cavity. In this study, we evaluated the minimum biofilm eradication concentration (MBEC) of antimicrobial agents against biofilm-forming NTHi strains. Twelve NTHi strains isolated from middle ear fluids of Japanese children with intractable AOM before antimicrobial treatment were evaluated for MBEC of fluoroquinolones in comparison with those of β-lactams and macrolides. AMPC and CDTR required much higher concentration, i.e., high MBECs, to suppress the biofilm formation of NTHi. In contrast, fluoroquinolones followed by macrolides showed lower MBECs. MBEC would be a good parameter to infer the efficacies of antimicrobials against NTHi in biofilm.

    The impact of bacterial conjugate vaccines on acute otitis media (AOM) is affected by several factors including population characteristics, bacterial etiology and vaccine conjugation method, carrier, and coverage. This study estimated the baseline etiology, distribution, and antibiotic susceptibility of bacterial serotypes that causes AOM in children aged Haemophilus influenzae (40.3% [56/139]) were predominant among the cultures that showed bacterial growth (85% [139/164]). All Streptococcus pneumoniae positive episodes were serotyped, 19F (21%) and 14 (17%) were the predominant serotypes; all Haemophilus influenzae strains were nontypeable. Streptococcus pneumoniae were resistant to penicillin (5%) and erythromycin (33%); Haemophilus influenzae were resistant to ampicillin (14%) and cefuroxime and cefotaxime (2% each).AOM in Chilean children is predominantly caused by Streptococcus pneumoniae and nontypeable Haemophilus influenzae. Use of a broad spectrum vaccine against these pathogens might aid the reduction of AOM in Chile.

    Full Text Available Abstract Background Otitis media is endemic in remote Indigenous communities of Australia’s Northern Territory. Alloiococcus otitidis is an outer ear commensal and putative middle ear pathogen that has not previously been described in acute otitis media (AOM in this population. The aims of this study were to determine the presence, antibiotic susceptibility and bacterial load of A. otitidis in nasopharyngeal and ear discharge swabs collected from Indigenous Australian children with AOM with perforation. Methods Paired nasopharyngeal and ear discharge swabs from 27 children with AOM with perforation were tested by A. otitidis quantitative PCR (qPCR. Positive swabs were cultured for 21 days. Total and respiratory pathogen bacterial loads in A. otitidis-positive swabs were determined by qPCR. Results A. otitidis was detected by qPCR in 11 ear discharge swabs from 10 of 27 (37% children, but was not detected in paired nasopharyngeal swabs. A. otitidis was cultured from 5 of 11 qPCR-positive swabs from four children. All A. otitidis isolates had minimum inhibitory concentrations consistent with macrolide resistance. All A. otitidis qPCR-positive swabs were culture-positive for other bacteria. A. otitidis bacterial load ranged from 2.2 × 104-1.1 × 108 cells/swab (median 1.8 × 105 cells/swab. The relative abundance of A. otitidis ranged from 0.01% to 34% of the total bacterial load (median 0.7%. In 6 of 11 qPCR-positive swabs the A. otitidis relative abundance was A. otitidis bacterial load and relative abundance measures were comparable to that of Haemophilus influenzae. Conclusions A. otitidis can be a dominant species in the bacterial communities present in the ear discharge of Indigenous children with AOM with perforation. The absence of A. otitidis in nasopharyngeal swabs suggests the ear canal as the likely primary reservoir. The significance of A. otitidis at low relative abundance is unclear; however, at higher relative

    Full Text Available ABSTRACT INTRODUCTION: Suppurative labyrinthitis continues to result in significant hearing impairment, despite scientific efforts to improve not only its diagnosis but also its treatment. The definitive diagnosis depends on imaging of the inner ear, but it is usually clinically presumed. OBJECTIVE: To analyze the clinical factors and hearing outcomes in patients with labyrinthitis secondary to middle ear infections and to discuss findings based on imaging test results. METHODS: Retrospective cohort study, based on the charts of patients admitted with middle ear infection-associated labyrinthitis. RESULTS: We identified 14 patients, eight (57% of whom were females and six (43% males. Mean age was 40 years. Cholesteatomatous chronic otitis media was diagnosed in six patients (43%, acute suppurative otitis media in six (43%, and chronic otitis media without cholesteatoma was diagnosed in two patients (14%. Besides labyrinthitis, 24 concomitant complications were identified: six cases (25% of labyrinthine fistula, five cases (21% of meningitis, five cases (21% of facial paralysis, five cases (21% of mastoiditis, two cases (8% of cerebellar abscess, and one case (4% of temporal abscess. There was one death. Eight (57% individuals became deaf, while six (43% acquired mixed hearing loss. CONCLUSION: Suppurative labyrinthitis was often associated with other complications; MRI played a role in the definitive diagnosis in the acute phase; the hearing sequel of labyrinthitis was significant.

  16. Deletion of the complement C5a receptor alleviates the severity of acute pneumococcal otitis media following influenza A virus infection in mice.

    Directory of Open Access Journals (Sweden)

    Hua Hua Tong

    Full Text Available There is considerable evidence that influenza A virus (IAV promotes adherence, colonization, and superinfection by S. pneumoniae (Spn and contributes to the pathogenesis of otitis media (OM. The complement system is a critical innate immune defense against both pathogens. To assess the role of the complement system in the host defense and the pathogenesis of acute pneumococcal OM following IAV infection, we employed a well-established transtympanically-induced mouse model of acute pneumococcal OM. We found that antecedent IAV infection enhanced the severity of acute pneumococcal OM. Mice deficient in complement C1qa (C1qa-/- or factor B (Bf -/- exhibited delayed viral and bacterial clearance from the middle ear and developed significant mucosal damage in the eustachian tube and middle ear. This indicates that both the classical and alternative complement pathways are critical for the oto-immune defense against acute pneumococcal OM following influenza infection. We also found that Spn increased complement activation following IAV infection. This was characterized by sustained increased levels of anaphylatoxins C3a and C5a in serum and middle ear lavage samples. In contrast, mice deficient in the complement C5a receptor (C5aR demonstrated enhanced bacterial clearance and reduced severity of OM. Our data support the concept that C5a-C5aR interactions play a significant role in the pathogenesis of acute pneumococcal OM following IAV infection. It is possible that targeting the C5a-C5aR axis might prove useful in attenuating acute pneumococcal OM in patients with influenza infection.

    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

    Background The oral probiotic Streptococcus salivarius K12 has been shown clearly to antagonize the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans, by releasing two bacteriocins named salivaricin A2 and salivaricin B. Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media. Methods We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®), and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product. Results The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90%) and/or acute otitis media (about 40%), calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period during which the product was not administered. Subjects tolerated the product well, with no side effects or dropouts reported. Conclusion Prophylactic administration of S. salivarius K12 to children with a history of recurrent oral streptococcal pathology reduced episodes of streptococcal pharyngeal infections and/or tonsillitis as

  1. New Insights into Eosinophilic Otitis Media.

    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.

  2. Quality of life measures in otitis media.

    Disabling hearing impairment is the world's most common disability. Traditionally, hearing levels measured by pure tone audiometry have been used to define and quantify hearing loss. The effects of disabling hearing loss on patients' quality of life can be profound, and audiometric data alone may not correlate with quality of life measures. Generic measures of quality of life can be used to compare different diseases, and as such are useful in resource allocation and burden of disease studies. Their disadvantage is that they are not disease-specific and can therefore under-estimate the effects of a disease on patients' quality of life. Disease-specific measures are more sensitive. In chronic otitis media, additional factors such as discharge augment the effect of hearing loss alone on quality of life. Many of the quality of life measures developed for chronic otitis media have been used to assess improvement following reconstructive surgery. Quality of life measures have also been used to assess the effect of paediatric otitis media. Quality of life measures also have utility in the developing world, where hearing impairment is a huge burden.

    2016-05-01

    We conducted a series of polymerase chain reactions (PCRs) in order to detect bacteria (7 species) and viruses (17 species) in middle ear fluid (MEF) and nasopharynx (Nph) of children with acute otitis media (AOM; n=179). Bacterial and viral nucleic acids were detected in MEF of 78.8% and 14.5% patients, respectively. The prevalence was as follows: Streptococcus pneumoniae, 70.4%; Haemophilus influenzae, 17.9%; Staphylococcus aureus, 16.8%; Streptococcus pyogenes, 12.3%; Moraxella catarrhalis, 9.5%; rhinovirus, 9.5%; and adenovirus, 3.4%. The overall rate of PCR-positive specimens for bacterial pathogens was 2.6 times higher, compared to culture results. The rate of PCR-positive results and the distribution of pathogens in the Nph were similar to those in the MEF. Nph PCR results had variable positive predictive values and high negative predictive values in predicting MEF findings. Our results indicate that Nph PCR could be a practical tool for examining respiratory pathogens in children with acute infections.

Results: the total effective rate in the observation group was significantly higher than that in the control group (93.22% vs 77.97%). The difference was statisti-cally significant; observation group of pathogenic bacteria negative rate (89.43%), effectively reduce the rate of tympanic pres-sure (94.92%) was significantly higher than the control group (65.71% and 81.36%). The difference was statistically significant. The hearing improvement, the onset time and the length of hospital stay in the observation group were significantly better than those in the control group. Difference was statistically significant. The incidence of adverse reactions in observation group was compared with that of control group (6.78% vs 16.95%). There was no statistically significant difference.Conclusion: the cura-tive effect of budesonide inhalation of secondary acute otitis media combined with ceftriaxone in the treatment of children with acute upper respiratory tract infection significantly, can significantly improve the clinical symptoms, improve the hearing level, promote the recovery of eustachian tube function.%目的:探讨唐山市急性上呼吸道感染继发急性中耳炎患儿临床治疗分析。方法:将118例急性上呼吸道感染继发急性中耳炎患儿分为两组,全部患者给予头孢曲松钠治疗,对照组采用氯霉素滴耳液治疗,观察组采用布地奈德混悬液雾化吸入治疗,对比两组疗效及临床症状改善情况。结果:观察组总有效率显著高于对照组(93

    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 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.

    Of the 249 children aged 5 to 9 years who live on Easter Island, 220 underwent complete otolaryngological evaluation. Twenty children were found to have otitis media (acute, chronic, or both). Three of these children were genetically impure natives, nine were of mixed parentage, and eight were "continentals" (with a birth origin other than the island). None of the genetically pure natives had otitis media. Our data show that, in a population with all factors in common except for familial and racial background, the point prevalence of otitis media is higher in children of mixed or continental origin than in genetically pure native children. The high prevalence of otitis media in children of mixed parentage and in one particular family of European ancestry suggests the presence of intrinsic or pronicity factors that are seemingly transmissible.

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

    Full Text Available Objective : To compare the effectiveness and safety of cefpodoxime and ciprofloxacin for the treatment of mild to moderate cases of acute exacerbation of chronic suppurative otitis media (AECSOM. Materials and Methods : Adult patients diagnosed with AECSOM were screened and patients fulfilling the inclusion criteria were randomized to receive either cefpodoxime 200 mg twice daily or ciprofloxacin 500 mg twice daily orally for 7 days. The primary outcome of this randomized, open-labeled, phase IV clinical trial (Registration Number - CTRI/2011/10/002079 was clinical success rate at day 14 visit and the secondary outcome was incidence of adverse events (AEs. Forty-six patients were enrolled: 23 in the cefpodoxime group and 23 in the ciprofloxacin group. Results : The clinical success rates were 95.6% in the cefpodoxime group versus 90.9% in the ciprofloxacin group. These rates are comparable, but no statistically significant difference was observed between the groups. Few mild and self-limiting AEs were observed and the tolerability of both the drugs was also good. Conclusion : The results of this randomized, open-labeled phase IV clinical trial showed that a 7-day course of cefpodoxime is therapeutically comparable to ciprofloxacin in terms of both clinical effectiveness and safety for the treatment of patients with AECSOM.

    Moraxella catarrhalis is a Gram-negative aerobic diplococcus that is currently the third most frequent cause of bacterial acute otitis media (AOM) in children. In this study, we developed an experimental murine AOM model by inoculating M. catarrhalis in the middle ear bulla and studied the local response to this inoculation, and modulation of its course by the pili of M. catarrhalis. The pili-positive and pili-negative M. catarrhalis showed differences in bacterial clearance and infiltration of inflammatory cells in the middle ear. Pili-negative M. catarrhalis induced a more delayed and prolonged immune response in the middle ear than that of pili-positive M. catarrhalis. TLR2, -4, -5 and -9 mRNA expression was upregulated in neutrophils that infiltrated the middle ear cavity during AOM caused by both pili-positive and pili-negative bacteria. TLR5 mRNA expression and TLR5 protein in the neutrophils were induced more robustly by pili-positive M. catarrhalis. This immune response is likely to be related to neutrophil function such as toll-like 5-dependent phagocytosis. Our results show that mice may provide a useful AOM model for studying the role of M. catarrhalis. Furthermore, we show that pili play an important role in enhancing M. catarrhalis clearance from the middle ear that is probably mediated through neutrophil-dependent TLR5 signaling.

    Mucosal immunity has a crucial role in controlling human respiratory tract infections. This study characterizes the naturally acquired mucosal antibody levels to three Streptococcus pneumoniae (Spn) protein antigens, pneumococcal histidine triad protein D (PhtD), pneumococcal choline binding protein A (PcpA), and pneumolysin (Ply), and assesses the association of the mucosal antibody levels with occurrence of acute otitis media (AOM) caused by Spn. Both nasopharyngeal (NP) immunoglobulin G (IgG) and IgA levels to all three proteins slightly decreased in children from 6 to 9 months of age and then gradually increased through 24 months of age. Spn NP colonization was associated with higher mucosal antibody levels to all three proteins. However, children with Spn AOM had 5-8-fold lower IgG and 3-6-fold lower IgA levels to the three proteins than children without AOM but asymptomatically colonized with Spn. Antigen-specific antibody levels in the middle ear fluid (MEF) were correlated with antibody levels in the NP. Children with AOM caused by Spn had lower antibody levels in both the MEF and NP than children with AOM caused by other pathogens. These results indicate that higher naturally acquired mucosal antibody levels to PhtD, PcpA and Ply are associated with reduced AOM caused by Spn.

    Full Text Available Abstract Background Acute Otitis Media (AOM is an important and common disease of childhood. Bacteria isolated from cases of clinically problematic AOM in German children were identified and characterized. Methods In a prospective non-interventional study in German children between 3 months and less than 60 months of age with Ear, Nose and Throat Specialist –confirmed AOM, middle ear fluid was obtained by tympanocentesis (when clinically indicated or by careful sampling of otorrhea through/at an existing perforation. Results In 100 children with severe AOM, Haemophilus influenzae was identified in 21% (18/21, 85.7% were non-typeable [NTHi], Streptococcus pneumoniae in 10%, S. pyogenes in 13% and Moraxella catarrhalis in 1%. H. influenzae was the most frequently identified pathogen in children from 12 months of age. H. influenzae and S. pneumoniae were equally prevalent in children aged 3–11 months, but S. pyogenes was most frequently isolated in this age group. NTHi AOM disease appeared prevalent in all ages. Conclusions NTHi, S. pneumoniae and S. pyogenes are implicated as important causes of complicated AOM in children in Germany. NTHi disease appears prevalent in all ages. The impact of vaccination to prevent NTHi and S. pneumoniae AOM may be substantial in this population and is worth investigating.

    Full Text Available Abstract Background Acute otitis media (AOM is one of the most frequently encountered bacterial infections in children aged Streptococcus pneumoniae (S. pneumoniae and non-typeable Haemophilus influenzae (NTHi are historically identified as primary AOM causes. Nevertheless, recent data on bacterial pathogens causing AOM in Latin America are limited. This prospective study aimed to identify and characterize bacterial etiology and serotypes of AOM cases including antimicrobial susceptibility in Methods From February 2008 to January 2009, children ≥3 months and Results Of the 106 enrolled children, 99 were included in the analysis. Bacteria were cultured from 62/99 (63% of samples with S. pneumoniae, H. influenzae, or S. pyogenes. The most commonly isolated bacteria were H. influenzae in 31/99 (31% and S. pneumoniae in 30/99 (30% of samples. The majority of H. influenzae episodes were NTHi (27/31; 87%. 19F was the most frequently isolated pneumococcal serotype (10/30; 33%. Of the 30 S. pneumoniae positive samples, 8/30 (27% were resistant to tetracycline, 5/30 (17% to erythromycin and 8/30 (27% had intermediate resistance to penicillin. All H. influenzae isolates tested were negative to beta-lactamase. Conclusions NTHi and S. pneumoniae are the leading causes of AOM in Colombian children. A pneumococcal conjugate vaccine that prevents both pathogens could be useful in maximizing protection against AOM.

    Clinical diagnosis of acute otitis media (AOM) in children is not easy. It was assumed that there is a difference ΔT between the Tympanic Membrane (TM) temperatures in the two ears in unilateral AOM and that an accurate measurement of ΔT may improve the diagnosis accuracy. An IR transmitting fiber, made of AgClBr, was coupled into a hand held otoscope and was used for the non-contact (radiometric) measurements of TT, the TM temperature. Experiments were carried out, first, on a laboratory model that simulated the human ear, including an artificial tympanic membrane and an artificial ear canal. Measurements carried out using commercially available tympanic thermometers shown that the temperature Tc of the ear canal affected the results. Tc did not affect the fiberoptic radiometer, and this device accurately measured the true temperature, TT of the tympanic membrane. A prospective blinded sampling of the TM temperature was then performed on 48 children with suspected AOM. The mean temperature difference between the ears, for children with unilateral AOM was ΔT = (0.68 +/- 0.27)°C. For children with bilateral AOM it was ΔT = (0.14+/-0.10)°C (p<0.001). It was demonstrated that afor unilateral AOM the difference ΔT was proportional to the systemic temperature. In conclusion, the fiberoptic interferometric measurements of the TM can be a useful non-invasive diagnostic tool for AOM, when combined with other data.

    Otitis media with effusion is one of the most common diseases in children. Its treatment remains controversial. Clinical practice guidelines of OME allow watchful waiting for 3 months before treatment if the child with OME is not at risk for speech/language/or learning problems. Tympanostomy tube insertion is the preferred initial procedure when a child becomes a surgical candidate. Complementary or alternative medicine is not recommended as a treatment for OME. This paper provides a systematic review of management of OME, which we hope will be helpful for clinicians.

    Full Text Available ABSTRACT INTRODUCTION: 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. OBJECTIVE: To investigate the main risk factors for otitis media and their prevalence in Sicilian children with and without upper respiratory tract infections. METHODS: 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. RESULTS: 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%.

    This observational study was conducted to know the bacteriological pattern of chronic suppurative otitis media. For this 110 patients of Chronic Suppurative Otitis Media (CSOM) were selected from January 2006 to December 2007 at the out patient department of Otolaryngology and Head Neck surgery, BSMMU and Dhaka Medical College Hospital, Dhaka. Among the 110 patients unilateral involvement was 76.36% and bilateral involvement was 23.64%. Ninety percent patients presented with tubotympanic variety and 10% patients presented with attico-antral variety. Bacteriologically pure growth was found in 79.09% cases, mixed growth in 10.91% cases, no growth in 10% cases. Only aerobic bacteria were isolated in the present series. Pseudomonas aeruginosa was the most common organism (43.68%) isolated in pure culture followed by staphylococcus aureus 27.59%, E. coli 10.35%, Kleibsiella spp. 9.19%, proteus spp. 8.04%. Amikacin was the most effective antibiotic followed by Gentamycin, Ciprofloxacin, Ceftazidime, Cetriaxone. Before giving therapy bacterial growth and sensitivity pattern is to be known where facilities are available.

    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 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.

    Full Text Available Abstract Background Recurrent otitis media is a common problem in young children. Echinacea and osteopathic manipulative treatment have been proposed as preventive measures, but have been inadequately studied. This study was designed to assess the efficacy of Echinacea purpurea and/or osteopathic manipulative treatment (OMT for prevention of acute otitis media in otitis-prone children. Methods A randomized, placebo-controlled, two-by-two factorial trial with 6-month follow-up, conducted 1999 – 2002 in Tucson, Arizona. Patients were aged 12–60 months with recurrent otitis media, defined as three or more separate episodes of acute otitis media within six months, or at least four episodes in one year. Ninety children (44% white non-Hispanic, 39% Hispanic, 57% male were enrolled, of which 84 had follow-up for at least 3 months. Children were randomly assigned to one of four protocol groups: double placebo, echinacea plus sham OMT, true OMT (including cranial manipulation plus placebo echinacea, or true echinacea plus OMT. An alcohol extract of Echinacea purpurea roots and seeds (or placebo was administered for 10 days at the first sign of each common cold. Five OMT visits (or sham treatments were offered over 3 months. Results No interaction was found between echinacea and OMT. Echinacea was associated with a borderline increased risk of having at least one episode of acute otitis media during 6-month follow-up compared to placebo (65% versus 41%; relative risk, 1.59, 95% CI 1.04, 2.42. OMT did not significantly affect risk compared to sham (44% versus 61%; relative risk, 0.72, 95% CI 0.48, 1.10. Conclusion In otitis-prone young children, treating colds with this form of echinacea does not decrease the risk of acute otitis media, and may in fact increase risk. A regimen of up to five osteopathic manipulative treatments does not significantly decrease the risk of acute otitis media. Trial registration ClinicalTrials.gov Identifier: NCT00010465

    We document the case of a 7-year-old boy who presented with pain in his left ear and trismus after a diagnosis of acute otitis media one week previously. His blood inflammatory markers were raised and magnetic resonance imaging (MRI) showed significant left temporomandibular joint effusion and partial attenuation of the left mastoid. A clinical diagnosis of septic arthritis of the TMJ was made and the patient was commenced on broad-spectrum antibiotics. Analysis using real time PCR enabled identification of the offending organism, confirmation of the diagnosis and antibiotic treatment to be specifically tailored for treatment.

    The objective of the present work was to study microflora in the middle ear of 100 patients aged from 30 to 70 years presenting with chronic purulent otitis media (CPOM) by microbiological and genetic (PCR) methods. An important role of persistence factors, pathogenicity, and microbial antibiotic resistance in the development of CPOM was demonstrated. The frequency of occurrence of herpes and papilloma viruses was estimated. The most common form of the mixed infection was two-component virobacterial associations (46.2%). Three-component associations of viruses with bacteria (Chlamydiae or Mycoplasmas) formed less frequently (34.6%). In 19.2% of the cases, yeast-like fungi of the genus Candida were identified in these associations.

    To compare the differential findings of tuberculous otitis media(TOM) with those of chronic sup purative otitis media with or without cholesteatoma, as seen on high resolution temporal bone CT. We retrospectively reviewed 14 cases of TOM, 30 cases of chronic suppurative otitis media(CSOM), and 30 cases of chronic otitis media with cholesteatoma(Chole). All had been pathologically confirmed. We evaluated the preservation of mastoid cells without sclerotic change, the location and extension of soft tissue to the external auditary canal, and erosion of ossicles, the tegmen tympani, scutum, bony labyrinth, facial nerve canal and sigmoid sinus, and the presence of intracranial complications. Soft tissue in the mastoid antrum was seen in all cases of TOM(100%), 29 cases of CSOM(96.7%), and 26 cases of Chole(86.7%). In contrast, the soft tissue in the entire middle ear cavity was noted in 13 cases of TOM(92.8%), 7 cases of CSOM(23.3%), and 12 cases of Chole(40%). Soft tissue extended to the superior aspect of the external auditory canal in 4 cases of TOM (28.6%) and 5 cases of Chole (16.7%). Mastoid air cells were seen in 9 cases of TOM (64.3%), 4 cases of CSOM (13.3%), and 3 cases of Chole(10%). Ossicular erosion was noted in 6 cases of TOM (42.9%), 12 cases of CSOM (40%), and 26 cases of Chole(86.7%), while in one case of TOM (7.1%), 5 cases of CSOM (16.7%), and 15 cases of Chole(50%) there was erosion of the scutum. In one case of TOM, follow-up CT study after 9 months of antituberculous medication without surgery revealed complete clearing of previously noted soft tissue in the middle ear cavity. Specific CT findings of TOM were not seen, but if there were findings of soft tissue in the entire middle ear cavity, soft tissue extension to the external auditory canal, preservation of mastoid air cells without sclerotic change, and intact scutum, TOM may be differentiated from other chronic otitis media.

  3. Gradenigo Syndrome: Unusual Consequence of Otitis Media

    Full Text Available Introduction: In 1904, Giuseppe Gradenigo published his case series on the triad of ipsilateral abducens nerve palsy, facial pain in the trigeminal nerve distribution, and suppurative otitis media, which would subsequently be referred to as Gradenigo syndrome. Case Report: Our patient was a 36-year-old female, 23 weeks pregnant, with a 6-day history of right-sided otalgia and hearing loss and a 4-day history of purulent otorrhea, who presented with severe, holocephalic headache, meningeal signs, fever, photophobia, and mental status decline. Lumbar puncture yielded a white blood cell count of 1,559 cells/mm3 with 95% polymorphonuclear leukocytes, a red blood cell count of 111 cells/mm3, a protein level of 61 mg/dl, and a glucose level of Streptococcus pneumoniae and treated with ceftriaxone. On the second hospital day, she developed horizontal diplopia due to right abducens nerve palsy and right mydriasis. Both symptoms resolved on the third hospital day. Erosion of temporal bone and opacification of mastoid air cells was shown on CT scan. A CT venogram showed an irregularity of the left transverse and superior sagittal sinuses. She was treated with enoxaparin for possible sinus thrombosis. Discussion: This case demonstrates rare but serious sequelae of otitis media and Gradenigo syndrome. Holocephalic headache from meningitis masked trigeminal pain. Involvement of the ipsilateral petrous apex and surrounding structures on imaging and clinical improvement with antibiotic treatment supports Gradenigo syndrome over intracranial hypertension due to venous sinus thrombosis as the cause of the abducens nerve palsy.

    Otitis media is a common disease in childhood that can adversely affect cognitive and educational outcomes. The literature in this area is equivocal, and findings may be influenced by research design. The impact of otitis media on individual children's development appears to depend on the inter-relationship between several factors. Children who have early-onset otitis media (under 12 months) are at high risk of developing long-term speech and language problems. Otitis media has been found to interact negatively with pre-existing cognitive or language problems. For biological or environmental reasons, some populations have a pattern of early onset, higher prevalence and episodes of longer duration; this pattern leads to a higher risk of long-term speech and language problems. These factors suggest that Indigenous children may be at higher risk of cognitive and educational sequelae than non-Indigenous children.

    A thorough understanding of the molecular details of the interactions between bacteria and host are critical to ultimately prevent disease. Recent technological advances allow simultaneous analysis of host and bacterial protein and metabolic profiles from a single small tissue sample to provide insight into pathogenesis. We used the chinchilla model of human otitis media to determine, for the first time, the most expansive delineation of global changes in protein and metabolite profiles during an experimentally induced disease. After 48 h of infection with nontypeable Haemophilus influenzae, middle ear tissue lysates were analyzed by high-resolution quantitative two-dimensional liquid chromatography-tandem mass spectrometry. Dynamic changes in 105 chinchilla proteins and 66 metabolites define the early proteomic and metabolomic signature of otitis media. Our studies indicate that establishment of disease coincides with actin morphogenesis, suppression of inflammatory mediators, and bacterial aerobic respiration. We validated the observed increase in the actin-remodeling complex, Arp2/3, and experimentally showed a role for Arp2/3 in nontypeable Haemophilus influenzae invasion. Direct inhibition of actin branch morphology altered bacterial invasion into host epithelial cells, and is supportive of our efforts to use the information gathered to modify outcomes of disease. The twenty-eight nontypeable Haemophilus influenzae proteins identified participate in carbohydrate and amino acid metabolism, redox homeostasis, and include cell wall-associated metabolic proteins. Quantitative characterization of the molecular signatures of infection will redefine our understanding of host response driven developmental changes during pathogenesis. These data represent the first comprehensive study of host protein and metabolite profiles in vivo in response to infection and show the feasibility of extensive characterization of host protein profiles during disease.

    Full Text Available ABSTRACT INTRODUCTION: It is an erroneous but commonly held belief that intracranial complications (ICCs of chronic and acute otitis media (COM and AOM are past diseases or from developing countries. These problems remain, despite improvements in antibiotic care. OBJECTIVE: This paper analyzes the occurrence and clinical characteristics and course of the main ICCs of otitis media (OM. METHODS: Retrospective cohort study of 51 patients with ICCs from OM, drawn from all patients presenting with OM to the emergency room of a large inner-city tertiary care hospital over a 22-year period. RESULTS: 80% of cases were secondary to COM of which the incidence of ICC was 0.8%; 20% were due to AOM. The death occurrence was 7.8%, hearing loss in 90%, and permanent neurological sequelae in 29%. Patients were 61% male. In the majority, onset of ear disease had occurred during childhood. Delay of diagnosis of both the initial infection as well as the secondary ICC was significant. ICCs included brain abscess and meningitis in 78%, and lateral sinus thrombosis, empyema and otitic hydrocephalus in 13%, 8% and 1% of cases, respectively. Twenty-seven neurosurgical procedures and 43 otologic surgery procedures were performed. Two patients were too ill for surgical intervention. CONCLUSION: ICCs of OM, although uncommon, still occur. These cases require expensive, complex and long-term inpatient treatment and frequently result in hearing loss, neurological sequelae and mortality. It is important to be aware of this potentiality in children with COM, especially, and maintain a high index of suspicion in order to refer for otologic specialty care before such complications occur.

    Eosinophilic otitis media (EOM) is a relatively rare, intractable, middle ear disease with extremely viscous mucoid effusion containing eosinophils. EOM is associated with adult bronchial asthma and nasal allergies. Conventional treatments for otitis media with effusion (OME) or for chronic otitis media (COM), like tympanoplasty or mastoidectomy, when performed for the treatment of EOM, can induce severe complications such as deafness. Therefore, it should be differentiated from the usual type of OME or COM. To our knowledge, the clinical and imaging findings of EOM of temporal bone are not well-known to radiologists. We report here the CT and MRI findings of two EOM cases and review the clinical and histopathologic findings of this recently described disease entity.

    ABSTRACT Tuberculous otitis media (TOM) is rare inENT department, and is frequently misdiagnosed as otitis media. Thus early systemic treatment is very important forTOM. We reported a case report withTOM to highlight development of the disease and difficulties in clinical treatment in late stage ofTOM. 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 middle ear response to otitis media includes transformation and hyperplasia of the mucosal epithelium and subepithelial connective tissue. Significant neovascularization is also noted, which occurs both to support the hypertrophied mucosa and to mediate the increased trafficking of leukocytes. We investigated the role of two known potent angiogenic growth factor families, the fibroblast growth factors (FGFs) and vascular endothelial growth factors (VEGFs), in middle ear mucosal angiogenesis. DNA microarrays were used to evaluate the expression of FGFs and VEGFs, as well as their receptors and unique signaling proteins, in the middle ears of mice undergoing a complete course of acute bacterial otitis media. In addition, a member of each family was introduced to the middle ear submucosal compartment of the normal middle ears of guinea pigs, by a continuous-release osmotic minipump system over 1 week. During the course of bacterial otitis media, a significant regulation of a number of genes important for angiogenesis was identified. Histologic evaluation of middle ear mucosa following micropump infusion of both FGF1 and VEGF-A showed significant angiogenesis at the site of infusion in comparison to control saline infusion. These results support a role for FGFs and VEGFs in the neovascularization of the middle ear mucosa during otitis media, and offer a potential avenue for therapeutic intervention.

    2010-01-01

    Full Text Available Eosinophilic otitis media (EOM is an intractable otitis media characterized by the presence of a highly viscous yellow effusion containing eosinophils. It mainly occurs in patients with bronchial asthma and is resistant to conventional treatments for otitis media. Here we discuss the role of IgE in the pathogenesis of EOM. In middle ear effusion, a significantly higher IgE level was detected in EOM patients than in control patients with common otitis media with effusion. This IgE level was significantly higher (about 10 fold than the serum IgE level. In addition, many IgE-immunopositive cells were found in the middle ear mucosa. The IgE staining was mainly observed on mast cell surfaces, but also partially in the cytoplasm of cells that appeared to be plasma cells. These results suggested that IgE is produced locally in the middle ear mucosa. The existence of high-level IgE may exacerbate eosinophilic inflammation in the middle ear. One of the most distinct characteristics of EOM is the high incidence of sensory hearing loss independent of age. High-tone hearing loss is more frequently found and more severe in EOM patients than in control patients with common chronic otitis media. The concentration of IgE in middle ear effusion significantly and positively correlated with bone conduction hearing levels at 2 kHz and 4 kHz in EOM patients. Overproduction of IgE locally in the middle ear may be related to the pathological condition of EOM and eventually cause inner ear damage.

    Full Text Available ABSTRACT Introduction: Otitis media is an inflammation of part or all of the mucosa of the middle ear, Eustachian tube, mastoid antrum, and mastoid cells. Patients with middle ear disease often comes as a chronic stage that causes hearing loss and expense secretions. Patients complain of hearing loss that disrupt the function of the social, educational and professional. School-age children may show poor results at school. One type of otitis media is chronic suppurative otitis media (CSOM, which is a chronic infection of the middle ear with tympanic membrane perforation and discharge of secretions from the middle ear continuous or intermittent, usually accompanied by hearing loss. Secretions may be thin or thick, clear or in the form of pus. CSOM formerly called otitis media with perforated. Diagnosis is made by history, physical examination. Two types of classification that is often used is CSOM types of benign and malignant types, and based on the activity of secretions out. Management of sudden deafness include conservative with some medical therapy depends on the type of CSOM and accompanying complications. Case: Male patient, 47 years old, came with complaints of discharge from the left ear since 1 month ago. Discharge yellowish-white, slightly viscous, odorless, out a little, and not itchy. Patients with a history of diabetes. Patients admitted before the water could get into the ear while swimming in the sea. At the present status and status generalist within normal limits. On the left ear found mucopurulent secretions. On the left tympanic membrane perforation in the visible region of the central part postero superior. Keywords:otitis, chronic, ear.

    Otitis media with effusion (OME) affects 28-38% of pre-school children, and it occurs due to the dysfunction of the auditory tube. Anatomical development of the auditory tube depends on the craniofacial growth and development. Deviations of normal craniofacial morphology and growth using cephalometric studies, may predict the evolution of otitis. Our goal in this paper is to determine if there are differences in craniofacial morphology between children with adenoid enlargement, with and without otitis media with effusion. This is a prospective study in which the sample consisted of 67 children (male and female) from 5 to 10 years old. All patients presented chronic upper airway obstruction due to tonsil and adenoid enlargement (>80% degree of obstruction). Thirty-three patients presented otitis media with effusion, for more than 3 months and 34 did not. The latter composed the control group. Standardized lateral head radiographs were obtained for all subjects. Radiographs were taken with patient positioned by a cephalostat and stayed with mandibles in centric occlusion and lips at rest. Radiographs were digitalized and specific landmarks were identified using a computer program Radiocef 2003, 5th edition. Measurements, angles and lines were taken of the basicranium, maxilla and mandible according to the modified Ricketts analysis. In addition, facial height and facial axis were determined. Children with otitis media with effusion present differences in the morphology of the face, regarding these measures: N-S (anterior cranial base length), N-ANS (upper facial height), ANS-PNS (size of the hard palate), Po-Or.N-Pog (facial depth), Ba-N.Ptm-Gn (facial axis), Go-Me (mandibular length) and Vaia--Vaip (inferior pharyngeal airway).

In some cases, acute OM progresses to chronic suppurative OM (CSOM), characterized by effusion and discharge, despite antimicrobial therapy. The emergence of antibiotic resistance and potential ototoxicity of antibiotics has created an urgent need to design non-conventional therapeutic strategies against OM based on modern insights into its pathophysiology. In this article, we review the role of innate immunity as it pertains to OM and discuss recent advances in understanding the role of innate immune cells in protecting the middle ear. We also discuss the mechanisms utilized by pathogens to subvert innate immunity and thereby overcome defensive responses. A better knowledge about bacterial virulence and host resistance promises to reveal novel targets to design effective treatment strategies against OM. The identification and characterization of small natural compounds that can boost innate immunity may provide new avenues for the treatment of OM. There is also a need to design novel methods for targeted delivery of these compounds into the middle ear, allowing higher therapeutic doses and minimizing systemic side effects.

    Full Text Available Corynebacterium pseudotuberculosis or caseous lymphadenitis is a common condition in sheep and goats. Two cases are described involving otitis media-interna and, in one case, cerebellar abscessation. The first case began with otitis externa and progressed to cerebellar abscessation, presumably as a result of C. pseudotuberculosis infection based on the macroscopic appearance of the abscess. The second case of otitis media-interna involved C. pseudotuberculosis with parasitic encephalitis or secondary meningo-encephalitis. Caseous lymphadenitis is a worldwide problem in livestock and also has zoonotic implications. Antimicrobial therapy of abscesses is often unrewarding due to the thick encapsulation of the abscesses and the extremely contagious nature of the organism. Alternative measures of treating this condition must be sought. In flocks or herds where caseous lymphadenitis has been diagnosed, it should be considered as a differential diagnosis for neurological conditions. The potential for spread must be kept in mind when it is suspected to be the cause of otitis in livestock.

    Nontypeable Haemophilus influenzae (NTHi) is a predominant organism of the upper respiratory nasopharyngeal microbiota. Its disease spectrum includes otitis media, sinusitis, non-bacteremic pneumonia and invasive infections. Protein-based vaccines to prevent NTHi infections are needed to alleviate these infections in children and vulnerable populations such as the elderly and those with chronic obstructive pulmonary disease (COPD). One NTHi protein is included in a pneumococcal conjugate vaccine and has been shown to provide efficacy. Our lab has been interested in understanding the immunogenicity of NTHi vaccine candidates P6, protein D and OMP26 for preventing acute otitis media in young children. We expect that continued investigation and progress in the development of an efficacious protein based vaccine against NTHi infections is achievable in the near future.

    The 2007 Recent Advances in Otitis Media Research Conference Panel Report provides an update on otitis media (OM) research published from 2003 to 2007. This report summarizes important trends in disease incidence and prevalence, describes established and newly identified risk factors for acute and chronic OM and OM with effusion, and conveys information on newly discovered genetic factors. In this report, researchers have described declining rates of OM diagnosis, antibiotic prescriptions, offices visits for OM, and middle ear surgery since the licensure and routine use of pneumococcal conjugate vaccine in infants. The panel report also recommends short and long term goals for current and future OM research.

  15. An evidence-based approach to treating otitis media.

    1996-12-01

    More than 20 years ago, a shrewd clinician remarked, "There is little evidence that those antimicrobial agents which hypothetically or in vitro are more effective ... are superior in the treatment of otitis when compared to penicillin alone." Several hundred clinical trials later, the advantages of broad spectrum drugs remain unproved, and questions remains as to whether antibiotics are required for most episodes of AOM. Further, antibiotics have been demoted to the status of optional therapy for OME. This situation is unlikely to change as new studies with new antibiotics proliferate. What is clear, however, is that accelerated patterns of bacterial resistance mandate an evidence-based approach to managing otitis media. Bacteria have an uncanny ability to learn new mechanisms of antibiotic resistance. A large part of bacterial "education" has undoubtedly been fueled by antibiotic prescriptions from well-intentioned physicians, with unrealistic expectations of drug efficacy. A judicious approach to antibiotic treatment of otitis media can result only from knowing the spontaneous course of the disorder and incremental effect of antibiotics on clinical outcomes. In this article, a series of unifying concepts are developed to help practicing clinicians with an evidence-based approach to managing otitis media. Critical review of the published evidence suggests that the most favorable outcomes from medical treatment will occur if practitioners: appreciate the favorable natural history of untreated otitis media realize that OME may take months to resolve following a single AOM episode modify risk factors to improve the odds of spontaneous resolution use pneumatic otoscopy and confirmatory tympanometry to diagnose OME recognize the limited impact of antibiotic therapy on treatment and prevention balance the benefits of antibiotics against the risk of accelerated bacterial resistance avoid repetitive, prolonged, or prophylactic antibiotic treatment of chronic OME avoid

    A duplication variant within the middle ear-specific gene A2ML1 cosegregates with otitis media in an indigenous Filipino pedigree (LOD score = 7.5 at reduced penetrance) and lies within a founder haplotype that is also shared by 3 otitis-prone European-American and Hispanic-American children but is absent in non-otitis-prone children and >62,000 next-generation sequences. We identified seven additional A2ML1 variants in six otitis-prone children. Collectively, our studies support a role for A2ML1 in the pathophysiology of otitis media.

  17. Eya4-deficient mice are a model for heritable otitis media

    OpenAIRE

    2008-01-01

    Otitis media is an extremely common pediatric inflammation of the middle ear that often causes pain and diminishes hearing. Vulnerability to otitis media is due to eustachian tube dysfunction as well as other poorly understood factors, including genetic susceptibility. As EYA4 mutations cause sensorineural hearing loss in humans, we produced and characterized Eya4-deficient (Eya4–/–) mice, which had severe hearing deficits. In addition, all Eya4–/– mice developed otitis media with effusion. A...

    We describe two cases of tuberculous otitis media studied with high-resolution computed tomography (CT). Findings included extensive soft tissue densities with fluid levels in the tympanic cavity, the antrum, the mastoid and petrous air cells. Multifocal bony erosions and reactive bone sclerosis were seen as well. CT proved valuable for planning therapy by accurately displaying the involvement of the various structures of the middle and inner ear. However, the specific nature of the disease could only be presumed. (orig.)

    Full Text Available OBJECTIVE: To analyze auditory processing test results in children suffering from otitis media in their first five years of age, considering their age. Furthermore, to classify central auditory processing test findings regarding the hearing skills evaluated. METHODS: A total of 109 students between 8 and 12 years old were divided into three groups. The control group consisted of 40 students from public school without a history of otitis media. Experimental group I consisted of 39 students from public schools and experimental group II consisted of 30 students from private schools; students in both groups suffered from secretory otitis media in their first five years of age and underwent surgery for placement of bilateral ventilation tubes. The individuals underwent complete audiological evaluation and assessment by Auditory Processing tests. RESULTS: The left ear showed significantly worse performance when compared to the right ear in the dichotic digits test and pitch pattern sequence test. The students from the experimental groups showed worse performance when compared to the control group in the dichotic digits test and gaps-in-noise. Children from experimental group I had significantly lower results on the dichotic digits and gaps-in-noise tests compared with experimental group II. The hearing skills that were altered were temporal resolution and figure-ground perception. CONCLUSION: Children who suffered from secretory otitis media in their first five years and who underwent surgery for placement of bilateral ventilation tubes showed worse performance in auditory abilities, and children from public schools had worse results on auditory processing tests compared with students from private schools.

    Full Text Available Otitis media is the bacterial infection of the middle ear usually accompanied with inflammation, effusions and pain. It can present clinically in two major forms: Acute Otitis Media (AOM and Otitis Media with Effusion (OME and it is one of the leading cause of hospital visits and antibiotic prescriptions amongst children and even adults. Antibiotic resistance is a global public health problem and Extended Spectrum β-Lactamase (ESBL enzymes is one of the new mechanisms of resistance in especially Gram negative bacteria including Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa. ESBLs are plasmid-mediated β-lactamase enzymes that hydrolyze extended-spectrum oxyimino 3rd generation cephalosporins and monobactams. Organisms producing ESBLs have remained important nosocomial and community-acquired pathogens over the years. Ear swab specimens of children (aged 0-7 with suspected Otitis media infections and who attended a tertiary hospital in Enugu, Nigeria were cultured on growth media. E. coli, K. pneumoniae and P. aeruginosa were isolated and identified by standard microbiological techniques. Antibiogram was conducted on all isolated ear pathogens by Kirby-Bauer disk diffusion method and ESBL production was evaluated by the Double Disk Synergy Test (DDST method. Imipenem and meropenem were the most active antibiotics against the E. coli, K. pneumoniae and P. aeruginosa ear pathogens. Sulphamethoxazole-trimethoprim was the least active agent against the tested ear pathogens and this was followed by ofloxacin, ciprofloxacin, gentamicin, cefotaxime and ceftazidime. None of the E. coli, K. pneumoniae and P. aeruginosa ear pathogens produced ESBLs by the method used. ESBL production by pathogenic bacteria confers on organisms the ability to be multidrug resistant. Their prompt and accurate detection from clinical specimens, together with reporting them along with hospitals routine antibiogram results is vital as this will help to

    Acute otitis media is the most frequent diagnosis in children visiting physicians' offices. Risk factors for otitis media have been widely studied. Yet, the correlation between bacterial carriage and the development of otitis media is not entirely clear. Our aim was to study in a population-based prospective cohort the risk factors for otitis media in the second year of life with special emphasis on the role of colonization with Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis. The study was embedded in the Generation R Study. Data on risk factors and doctor-diagnosed otitis media were obtained by midwives, hospital registries and postal questionnaires in the whole cohort (n = 7,295). Nasopharyngeal swabs were obtained at the age of 1.5, 6 and 14 months in the focus cohort (n = 1,079). Of these children, 2,515 (47.2%) suffered at least one period of otitis media in their second year of life. The occurrence of otitis media during the follow-up period in the first 6 months of life and between 6 and 12 months of age was associated with the risk of otitis media in the second year of life (aOR, 1.83 95% CI 1.24-2.71 and aOR 2.72, 95% CI 2.18-3.38, respectively). Having siblings was associated with an increased risk for otitis media in the second year of life (aOR 1.42, 95% CI 1.13-1.79). No associations were found between bacterial carriage in the first year of life and otitis media in the second year of life. In our study, otitis media in the first year of life is an independent risk factor for otitis media in the second year of life. Surprisingly, bacterial carriage in the first year of life did not add to this risk. Moreover, no association was observed between bacterial carriage in the first year of life and otitis in the second year of life.

  5. Human evolutionary history: consequences for the pathogenesis of otitis media.

    The pathogenesis of otitis media is multifactorial, but the role of evolution on its development has not been addressed. We posit that the high prevalence of middle-ear disease is most likely restricted to humans, in contrast to other wild species, because the associated hearing loss would have reduced the fitness of affected individuals as a result of predation. We present here the possible consequences of two human adaptations that may have resulted in ubiquitous otitis media: the interaction of bipedalism and increased brain size, and the loss of facial prognathism resulting from speech or cooking. As a consequence of our adaptation for bipedalism, the female pelvic outlet is constricted, which, in the context of a rapidly enlarging brain, results in humans being born 12 months too soon. Significantly, immature eustachian tube structure and function, in conjunction with an immature immune system, helps to explain the high incidence of otitis media in the first year of life. But the persistence of middle-ear disease beyond this stage is not explained by "immaturity." The morphology of the palate changed with the adaptations that produced facial flattening, with concomitant effects on eustachian tube function. These changes resulted in relatively poor human physiologic tubal function in comparison to the nonhuman primate.

    Full Text Available Abstract Background Middle ear disease (otitis media is common and frequently severe in Australian Aboriginal children. There have not been any recent large-scale surveys using clear definitions and a standardised middle ear assessment. The aim of the study was to determine the prevalence of middle ear disease (otitis media in a high-risk population of young Aboriginal children from remote communities in Northern and Central Australia. Methods 709 Aboriginal children aged 6–30 months living in 29 communities from 4 health regions participated in the study between May and November 2001. Otitis media (OM and perforation of the tympanic membrane (TM were diagnosed by tympanometry, pneumatic otoscopy, and video-otoscopy. We used otoscopic criteria (bulging TM or recent perforation to diagnose acute otitis media. Results 914 children were eligible to participate in the study and 709 were assessed (78%. Otitis media affected nearly all children (91%, 95%CI 88, 94. Overall prevalence estimates adjusted for clustering by community were: 10% (95%CI 8, 12 for unilateral otitis media with effusion (OME; 31% (95%CI 27, 34 for bilateral OME; 26% (95%CI 23, 30 for acute otitis media without perforation (AOM/woP; 7% (95%CI 4, 9 for AOM with perforation (AOM/wiP; 2% (95%CI 1, 3 for dry perforation; and 15% (95%CI 11, 19 for chronic suppurative otitis media (CSOM. The perforation prevalence ranged from 0–60% between communities and from 19–33% between regions. Perforations of the tympanic membrane affected 40% of children in their first 18 months of life. These were not always persistent. Conclusion Overall, 1 in every 2 children examined had otoscopic signs consistent with suppurative ear disease and 1 in 4 children had a perforated tympanic membrane. Some of the children with intact tympanic membranes had experienced a perforation that healed before the survey. In this high-risk population, high rates of tympanic perforation were associated with high

    Full Text Available Introduction: In spite of the fact that acute otitis media is a systemic and symptomatic disease with sever otalgia, otitis media with effusion (OME is an asymptomatic and silent disease. OME is the most common cause of conductive hearing loss in children and has adverse effects on speech development and cognitive skills. Results: Among 1001 children under study, 57 subjects (5.7% were diagnosed with OME, more than 50% of which were asymptomatic. Periodic otalgia and turning up television volume were the most common symptoms. Conclusion: Regarding the improved knowledge on diagnosis and treatment of OME especially in younger children, hearing problems or cognitive and linguistic skills retardation may be avoided by promoting general information.

    Antipyretics and/or anti-inflammatory drugs along with a wait-and-see approach are the only treatments recommended in early acute otitis media (AOM) or viral pharyngitis. Propolis has been widely investigated for its antibacterial, antiviral, and anti-inflammatory properties and could perhaps be administered as an add-on therapy during watchful waiting in AOM or for better control of symptoms in nonstreptococcal pharyngitis. However, propolis has well-known problems of poor solubility and low oral bioavailability. We therefore analyzed a proprietary propolis-based product (Propolisina®) developed to overcome these limitations, in a retrospective, open-label, controlled study of Streptococcus pyogenes-negative children with a diagnosis of AOM or pharyngitis. Our results show that the use of propolis supplement for 72 hours lessens the severity of AOM and viral pharyngitis, reduces the use of antipyretics and anti-inflammatory drugs, and decreases the rate of evolution to tracheitis, bronchitis, and rhinosinusitis. Our study shows that propolis could be used as a safe add-on therapy in case of AOM and/or viral pharyngitis. PMID:27956842

    Acute conjunctivitis is the most common ocular disorders among children and frequently concomitant with acute otitis media (AOM) as conjunctivitis-otitis syndrome. In this study, we evaluated prevalence of causative pathogens and PCR-based genotypes of Haemophilus influenzae and Streptococcus pneumoniae among children with conjunctivitis-otitis media syndrome. Nontypeable H. influenzae (NTHi) is identified most often at 61.8% in conjunctiva exudates followed by S. pneumoniae at 28.2% and Moraxella catarrhalis at 19.1%. Genetic β-lactamase nonproducing ampicillin resistant (gBLNAR) strains of NTHi and genetic penicillin resistant S. pneumoniae (gPRSP) were identified at 72.1% and at 74.2% among conjunctiva isolates by polymerase chain reaction (PCR), respectively. Pneumococcal strains having either ermB or mefE genes were identified at 93.5% among conjunctiva isolates. The restriction fragment of patterns of 89.7% pairs of H. influenzae isolates and 100% pairs of pneumococcal isolates from conjunctiva exudates, middle ear fluids (MEFs) and nasopharyngeal swabs were identical. In contrast to the previous reports, most prevalent strains from conjunctivitis-otitis media syndrome was BLNAR H. influenzae in this study. The causative pathogen responsible for acute conjunctivitis will be originated from the nasopharynx. In the absence of MEFs one can possibly rely on the nasopharyngeal culture to guide an appropriate treatment.

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.

    Background: The treatment results of symptomatic radiation therapy of the Eustachian tube in chronic otitis media had to be evaluated retrospectively. Patients and Methods: Between 1980 and 1997, 66 patients were referred for therapy. The median age was 58 years. In the clinical presentation, all the patients had a hearing impairment, 35 patients complained of pain, 21 had otorrhea. In their history, 20 patients indicated chronic recurrent infections. The complaints lasted for 4.7 years in the median, primary conservative (adstringentia, antibiotics) and surgical treatment (paracentesis, tympanic tubule, tympanoplastic) did not lead to lasting cure. In 40 of 66 patients, finally radiation therapy was done of both Eustachian tubes. With opposed fields and cobalt-60 photons a total dose of 6 Gy at single doses of 1 Gy, three times a week, was applied. Under the causes for exclusion of radiation therapy were non-acceptance of the patients (nine), prior radiation therapies (six) or spontaneous improvement after initial presentation in our department. The treatment results were evaluated by interviews of the patients and regular otorhinolaryngological examinations. Results: There were no side effects noticed. 28 of 40 (70%) patients reported a significant improvement that could be verified by objective otorhinolaryngological examinations. In the group of 26 nonirradiated patients, 22 could be interviewed indicating in 16 cases (72%) that the complaints were unchanged and chronic otitis media was lasting. In a subgroup analysis concerning the duration of otitis media radiation therapy proved more effective in an acute and subacute stadium of disease of up to 5 years duration, while the patients resistant to radiation therapy were entirely in a chronic stage of disease exceeding 5 years duration.

    Recurrent otitis media may be related to defects in specific antibody production, as suggested previously. This might be reflected in lower antibody responses to vaccinations administered in the context of the national childhood vaccination program in children suffering from recurrent otitis media.

    Interpretation: 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.

    Full Text Available Diseases of the outer and middle ear (Otitis externa and Otitis media are a frequent clinical problem which is mostly approached in the wrong way. We believe that the approach to a diseased ear in dogs or cats by practicing veterinarians in our country is most often incorrect. Namely, the conventional approach to inflammation of the outer ear is narrowed down to cleaning the ear, usually with cotton wool and hydrogen peroxide, and then by applying ear drops for veterinary or human use over the next few days. A somewhat more conscientious approach implies treatment using antibiotics, topical and/or systemic, but based on an antibiogram. If the presence of a foreign body is suspected, the veterinarian will use an otoscope, and this is where the entire diagnostic approach in our conditions usually ends. Such procedures most often fail to resolve the problem, so that the disease recurs after a certain time or becomes chronic recurrent Otitis externa, which is one of the biggest problems in dog dermatology. Experience shows that veterinarians here are generally not familiar with the pathogenesis of outer and middle ear infection, and that this is the reason why they approach diagnostics and therapy in the wrong way. The most important thing is to have in mind that bacteria and fungi linked with a pathological process in the ear canal are merely opportunistic microorganisms, and never primary pathogens, themselves responsible for Otitis externa. Antibiotic or antimycotic treatment does not cure the basic disease which led to the inflammation, but only its consequences. A large number of factors involved in the inflammation of the outer or middle ear are traditionally divided into primary, predisposing, secondary, and underlying. The basis for the successful treatment of Otitis externa and Otitis media is the recognition, elimination or control of the primary factors (atopy, nutritive allergy, keratinization disorders, parasitic infestations.

    Hypertrophic adenoids with otitis media with effusion is a common infectious disease and present a serious otological problem in children. Cytokines, potent inflammatory mediators, play important role in the initiation of immunological response in otitis media. Adenoids excised due to hypertrophy with or without chronic otitis media with effusion were used to isolate mononuclear cells. Secretion of cytokines by non-stimulated and PHA-stimulated cells was determined by specific ELISAs. We found a significant increase in the production of IL-5 and TNF-α secreted by adenoidal cells of children with otitis media with effusion compared to group with hypertrophic adenoids. No differences were found in the secretion of IL-8, IL-6, and IL-10 between these two groups of patients. Our results suggest a difference between the immunological responses in the course of hypertrophic adenoids with otitis media as compared to hypertrophic adenoids.

  1. A mouse model of otitis media identifies HB-EGF as a mediator of inflammation-induced mucosal proliferation.

    Full Text Available Otitis media is one of the most common pediatric infections. While it is usually treated without difficulty, up to 20% of children may progress to long-term complications that include hearing loss, impaired speech and language development, academic underachievement, and irreversible disease. Hyperplasia of middle ear mucosa contributes to the sequelae of acute otitis media and is of important clinical significance. Understanding the role of growth factors in the mediation of mucosal hyperplasia could lead to the development of new therapeutic interventions for this disease and its sequelae.From a whole genome gene array analysis of mRNA expression during acute otitis media, we identified growth factors with expression kinetics temporally related to hyperplasia. We then tested these factors for their ability to stimulate mucosal epithelial growth in vitro, and determined protein levels and histological distribution in vivo for active factors.From the gene array, we identified seven candidate growth factors with upregulation of mRNA expression kinetics related to mucosal hyperplasia. Of the seven, only HB-EGF (heparin-binding-epidermal growth factor induced significant mucosal epithelial hyperplasia in vitro. Subsequent quantification of HB-EGF protein expression in vivo via Western blot analysis confirmed that the protein is highly expressed from 6 hours to 24 hours after bacterial inoculation, while immunohistochemistry revealed production by middle ear epithelial cells and infiltrating lymphocytes.Our data suggest an active role for HB-EGF in the hyperplasia of the middle ear mucosal epithelium during otitis media. These results imply that therapies targeting HB-EGF could ameliorate mucosal growth during otitis media, and thereby reduce detrimental sequelae of this childhood disease.

    Full Text Available Anouk Speets1, Judith Wolleswinkel1, Cristina Cardoso21Pallas health research and consultancy, Rotterdam, the Netherlands; 2GlaxoSmithKline, Algés, PortugalAbstract: This study aimed to estimate the resource consumption and societal impact of otitis media (OM in children younger than five years of age in Portugal. An Internet survey on generic childhood symptoms and diseases was administered to a sample of parents. This self-report survey had been previously implemented in other European countries. Medically confirmed OM was defined as symptoms of earache or “running ear” and/or a diagnosis of OM provided by a medical doctor. Direct medical, nonmedical, and indirect nonmedical costs were calculated for individual cases. Mean total costs per OM episode were estimated at €334. This corresponds to an estimated societal impact of 72 million €/year, of which 39% were indirect nonmedical costs. An epidemiological study should help to confirm the results of this study, and evaluate whether an intervention to reduce the occurrence and/or duration of OM may have an impact on societal costs and quality of life for affected families.Keywords: otitis media, costs, societal burden, Portugal

    Full Text Available A 40-year-old female presented with purulent exudate through the left auditive duct and pain in the left ear region, which intensified during mastication. After collection of the pus from the left ear lesion, amoxicillin-clavulanic acid for seven days was prescribed for a presumed diagnosis of acute otitis. Four days later, the pus culture grew V. fluvialis which is further identified by API 20E identification system (bioMérieux. Following the successful completion of a course of antibiotics, the patient recovered completely and without complication. To the best of our knowledge, this is the first case of Vibrio fluvialis otitis after swimming in an immunocompetent patient.

    Streptococcus pneumoniae is an important cause of acute otitis media (AOM). The aim of this study was to evaluate trends in antibiotic resistance and circulating serotypes of pneumococci isolated from middle ear fluid of French children with AOM during the period 2001-2011, before and after the introduction of the PCV-7 (2003) and PCV-13 (2010) vaccines. Between 2001 and 2011 the French pneumococcal surveillance network analysed the antibiotic susceptibility of 6683 S. pneumoniae isolated from children with AOM, of which 1569 were serotyped. We observed a significant overall increase in antibiotic susceptibility. Respective resistance (I+R) rates in 2001 and 2011 were 76.9% and 57.3% for penicillin, 43.0% and 29.8% for amoxicillin, and 28.6% and 13.0% for cefotaxime. We also found a marked reduction in vaccine serotypes after PCV-7 implementation, from 63.0% in 2001 to 13.2% in 2011, while the incidence of the additional six serotypes included in PCV-13 increased during the same period, with a particularly high proportion of 19A isolates. The proportion of some non-PCV-13 serotypes also increased between 2001 and 2011, especially 15A and 23A. Before PCV-7 implementation, most (70.8%) penicillin non-susceptible pneumococci belonged to PCV-7 serotypes, whereas in 2011, 56.8% of penicillin non-susceptible pneumococci belonged to serotype 19A. Between 2001 and 2011, antibiotic resistance among pneumococci responsible for AOM in France fell markedly, and PCV-7 serotypes were replaced by non-PCV-7 serotypes, especially 19A. We are continuing to assess the impact of PCV-13, introduced in France in 2010, on pneumococcal serotype circulation and antibiotic resistance.

    Otitis media is a common reason for hearing loss, especially in children. Otitis media is a multifactorial disease and environmental factors, anatomic dysmorphology and genetic predisposition can all contribute to its pathogenesis. However, the reasons for the variable susceptibility to otitis media are elusive. MCPH1 mutations cause primary microcephaly in humans. So far, no hearing impairment has been reported either in the MCPH1 patients or mouse models with Mcph1 deficiency. In this study, Mcph1-deficient (Mcph1(tm1a) (/tm1a) ) mice were produced using embryonic stem cells with a targeted mutation by the Sanger Institute's Mouse Genetics Project. Auditory brainstem response measurements revealed that Mcph1(tm1a) (/tm1a) mice had mild to moderate hearing impairment with around 70% penetrance. We found otitis media with effusion in the hearing-impaired Mcph1(tm1a) (/tm1a) mice by anatomic and histological examinations. Expression of Mcph1 in the epithelial cells of middle ear cavities supported its involvement in the development of otitis media. Other defects of Mcph1(tm1a) (/tm1a) mice included small skull sizes, increased micronuclei in red blood cells, increased B cells and ocular abnormalities. These findings not only recapitulated the defects found in other Mcph1-deficient mice or MCPH1 patients, but also revealed an unexpected phenotype, otitis media with hearing impairment, which suggests Mcph1 is a new gene underlying genetic predisposition to otitis media.

    Full Text Available 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

    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.

    We hypothesized that capsular switch event, in which pneumococcus acquires a new capsule operon by horizontal gene transfer, may result in emergence of strains with increased virulence in acute otitis media. Using serotype 6A strain from a patient with invasive pneumococcal disease and clonally distant serotype 6C strain isolated from asymptomatic carrier we created 6A:6C (6A background with 6C capsule) capsular transformants and applied whole genome macro-restriction analysis to assess conservation of the 6A chassis. Next, we assessed complement (C3) and antibodies deposition on surface of pneumococcal cells and tested capsule recipient, capsule donor and two 6A:6C transformants for virulence in chinchilla experimental otitis media model. Both 6A:6C(1 or 2) transformants bound less C3 compared to 6C capsule-donor strain but more compared to serotype 6A capsule-recipient strain. Pneumococci were present in significantly higher proportion of ears among animals challenged with either of two 6A:6C(1 or 2) transformants compared to chinchillas infected with 6C capsule-donor strain [p < 0.001] whereas a significantly decreased proportion of ears were infected with 6A:6C(1 or 2) transformants as compared to 6A capsule-recipient strain. Our observations though limited to two serotypes demonstrate that capsular switch events can result in Streptococcus pneumoniae strains of enhanced virulence for respiratory tract infection.

    Full Text Available To investigate the possible role of adenoid mast cells in the etiology of secretory otitis media. Between 2001-2002, 25 patients with chronic adenoitis and chronic secretory otitis media and 25 patients with isolated adenoid hypertrophy were included to the study. Adenoidectomy performed to the all patients under general anesthesia. Adenoidectomy specimens were evaluated under the light microscopy and the number of mast cells were calculated for each patient. The number of mast cells were compared between two groups. The number of mast cells were between 4-84 in the otitis media with effusion and adenoid hypertrophy group (median:52, however it was between 2-63 (median: 23 in the isolated adenoid hypertrophy group. When comparing the two groups using Mann-Withney U test, the number of mast cells found to be significantly higher in the chronic secretory otitis media group (p<0.001.Based on our findings there is a relationship between increased adenoid mast cells and otitis media with effusion and these cells may have a possible role in the etiology of chronic secretory otitis media.

    Full Text Available The aim of this study was to determine the serotype and clonal distribution of pneumococci causing acute otitis media (AOM and their relationship with recurrences and mixed infections with other microorganisms under the influence of the 7-valent pneumococcal conjugate vaccine (PCV7. To do this, all pneumococcal isolates collected from the spontaneous middle-ear drainage of children <5 years old diagnosed of AOM by their pediatrician or their general practitioner from 1999 to 2010 were phenotypically characterized and the most frequent serotypes were genotyped. In the 12-year study, 818 episodes of pneumococcal AOM were detected, mostly (70.5% in children younger than 2 years old. In 262 episodes (32%, the pneumococci were isolated with another bacterium, mainly (n=214 Haemophilus influenzae. Mixed infections were similar in children under or over 2 years old. The most frequent serotypes were 19A (n=227, 27.8%, 3 (n=92, 11.2% and 19F (n=74, 9%. Serotypes included in the PCV7 sharply decreased from 62.4% in the pre-vaccination (1999-2001 to 2.2% in the late post-vaccination period (2008-2010. Serotype diversity steadily increased after the introduction of the PCV7 but decreased from 2008-2010 due to the predominant role of serotype 19A isolates, mostly ST276 and ST320. The prevalence of serotype 3 doubled from 6.1% (20/326 in 1999-2004 to 14.6% (72/492 in 2005-2010. Relapses mainly occurred in male infants infected with isolates with diminished antimicrobial susceptibility. Reinfections caused by isolates with the same serotype but different genotype were frequent, highlighting the need for genetic studies to differentiate among similar strains. In conclusion, the main change in pneumococcal AOM observed after the introduction of the PCV7 was the sharp decrease in vaccine serotypes. Also notable was the high burden of serotype 19A in total pneumococcal AOM before and especially after the introduction of the PCV7, as well as in relapses and

    Full Text Available Chronic suppurative otitis media (CSOM is the result of an initial episode of acute otitis media and is characterized by recurrent discharge from the middle ear through a tympanic perforation. It is an important cause of preventable hearing loss, especially in developing countries. Most approaches to treatment have been unsatisfactory or are very expensive and difficult. As per Acharya Sushruta Karnasrava is a disease characterized by ear discharge. Gandhaka taila is a unique oil based herbo-mineral formulation especially mentioned for Karnasrava with the procedure of karnapurana. To provide clinical evidence and to prove Gandhaka taila as a safe and effective medicine in chronic suppurative otitis media, this study has been carried out. In this study, 23 patients fulfilling the diagnostic and inclusion criteria of CSOM were selected and Gandhaka taila was instilled in to the affected ear for 7 days. The efficacy of the drug was analyzed in terms of the relief produced in the signs and symptoms before and after treatment. The paired t-test was used to check the significance of subjective and objective criteria. The results of the study were found encouraging and there was also a significant reduction in ear discharge.

    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 smoking (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.

    In recent years, the multislice CT system has come into practical use that enables table movement of half mm, resulting in a significant improvement in resolution. The use of this CT system enables to depict the entire auditory ossicles, including the stapes. 3D reconstruction was performed using helical CT data in 5 patients with chronic otitis media and 5 patients with cholesteatoma. An Aquilion Multi (Toshiba) multislice helical CT scanner and a Xtension (Toshiba) image workstation were used in this study. We demonstrated the 3D display with axial, coronal and sagittal images. Compared with the normal ears, it was necessary to set a higher threshold for the affected ears. It is important to select suitable threshold for demonstration of 3D images optimally. Bone destruction of the stapes was confirmed at surgery in 2 ears. The stapes was observed at 3D-CT imaging in other 18 ears. It was found that the 3D images of the ossicular destruction in ears with cholesteatoma were consistent with surgical findings. It is therefore concluded that 3D imaging of the middle ear using a multislice CT scanner is clinically useful. (author)

    We report the application of Optical Coherence Tomography (OCT) to various types of human cases of otitis media (OM). Whereas conventional diagnostic modalities for OM, including standard and pneumatic otoscopy, are limited to visualizing the surface information of the tympanic membrane (TM), OCT is able to effectively reveal the depth-resolved microstructural below the TM with a very high spatial resolution. With the potential advantage of using OCT for diagnosing different types of OM, we examined in-vivo the use of 840 nm wavelength, and OCT spectral domain OCT (SDOCT) techniques, in several human cases including normal ears, and ears with adhesive and effusion types of OM. Peculiar positions were identified in two-dimensional OCT images of abnormal TMs compared to images of a normal TM. Analysis of A-scan (axial depth-scans) data from these positions could successfully identify unique patterns for different constituents within effusions. These OCT images may not only be used for constructing a database for the diagnosis and classification of OM, but they may also demonstrate the feasibility and advantages for upgrading the current otoscopy techniques.

    In an attempt to evaluate the feasibility of the tympanometry in detecting the middle ear effusion (MEE) in secretory otitis media (SOM) in childhood, the findings of the computed tomography (CT) were evaluated whether they were compatible with that of tympanometry in 27 cases (51 ears) of SOM. Tympanometry (tympanogram, static compliance measurement and stapedial reflex test), pure tone audiometry and high resolution CT were performed sequentially, and the CT findings were compared with the results of the other tests. The conclusions obtained were summarized as follows. 1. Among the tests performed, tympanogram appeared to be the most reliable measure in detection of MEE. 2. Fifteen ears out of 16 with type B tympanograms and 6 ears out of 15 with type C/sub 2/ tympanograms, were diagnosed by CT as having MEE. MEE occupied the entire middile ear space in most ears with type B tympanograms. By contrast, in the ears with type C/sub 2/ tympanograms, air containing space of varying size were always observed even in the ears with MEE.

    Full Text Available Abstract Background Otitis media is one of the most common infections of early childhood. Surfactant protein A functions as part of the innate immune response, which plays an important role in preventing infections early in life. This prospective study utilized a candidate gene approach to evaluate the association between polymorphisms in loci encoding SP-A and risk of otitis media during the first year of life among a cohort of infants at risk for developing asthma. Methods Between September 1996 and December 1998, women were invited to participate if they had at least one other child with physician-diagnosed asthma. Each mother was given a standardized questionnaire within 4 months of her infant's birth. Infant respiratory symptoms were collected during quarterly telephone interviews at 6, 9 and 12 months of age. Genotyping was done on 355 infants for whom whole blood and complete otitis media data were available. Results Polymorphisms at codons 19, 62, and 133 in SP-A1, and 223 in SP-A2 were associated with race/ethnicity. In logistic regression models incorporating estimates of uncertainty in haplotype assignment, the 6A4/1A5haplotype was protective for otitis media among white infants in our study population (OR 0.23; 95% CI 0.07,0.73. Conclusion These results indicate that polymorphisms within SP-A loci may be associated with otitis media in white infants. Larger confirmatory studies in all ethnic groups are warranted.

    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.

    Full Text Available Introduction. Otitis media with effusion is a common pediatric disease whose diagnosis is based on pneumatic otoscopy, pure-tone audiometry, and tympanometry. The aim of this study was to evaluate transiently evoked otoacoustic emissions in the diagnosis of otitis media with effusion as compared to tympanometry. Patients and Methods. 38 children with bilateral otitis media with effusion were studied. 40 normal children of similar age and sex were used as controls. All subjects underwent pneumatic otoscopy, standard pure-tone audiometry, tympanometry, and transiently evoked otoacoustic emissions. Results. In the group of children with bilateral otitis media, transiently evoked otoacoustic emissions were absent in 51 ears (67%. In the remaining 25 ears (33% the mean emission amplitude was reduced, as compared to the mean value of the control group. Conclusions. Transiently evoked otoacoustic emissions should be included in the diagnostic workup of otitis media with effusion because it is a fast, reliable, and objective test. Transiently evoked otoacoustic emissions should always be used in conjunction with tympanometry, because a more meaningful interpretation of transiently evoked otoacoustic emissions measures is possible.

    Unnecessary prescribing of antibiotics is costly, leads to serious unintended side effects, and increases the risk of developing antibiotic resistance. Children are at high risk of receiving unnecessary antibiotics because they consume more antibiotics than any other age group, likely due to inaccurate prescribing by health care providers. Treatment of acute otitis media is the most common reason children are prescribed antibiotics. Evidence-based guidelines regarding the appropriate treatment of nonsevere acute otitis media in children have been established. A retrospective, descriptive, chart review project was completed comparing the diagnosis and treatment of acute otitis media in children six months to 12 years of age in clinics and the emergency department of a large academic medical center with the American Academy of Pediatrics' treatment guidelines. Findings of the chart review included 100 patient encounters. Documentation indicated that although none of these children with acute otitis media met the guideline criteria for antibiotics, 92 of the 100 children were prescribed antibiotics.

    Full Text Available Abstract Background Bacteria which are metabolically active yet unable to be cultured and eradicated by antibiotic treatment are present in the middle ear effusion of children with chronic otitis media with effusion (COME and recurrent acute otitis media (rAOM. These observations are suggestive of biofilm presence or intracellular sequestration of bacteria and may play a role in OM pathogenesis. The aim of this project is to provide evidence for the presence of otopathogenic bacteria intracellularly or within biofilm in the middle ear mucosa of children with COME or rAOM. Methods Middle ear mucosal biopsies from 20 children with COME or rAOM were examined for otopathogenic bacteria (either in biofilm or located intracellularly using transmission electron microscopy (TEM or species specific fluorescent in situ hybridisation (FISH and confocal laser scanning microscopy (CLSM. One healthy control biopsy from a child undergoing cochlear implant surgery was also examined. Results No bacteria were observed in the healthy control sample. In 2 of the 3 biopsies imaged using TEM, bacteria were observed in mucus containing vacuoles within epithelial cells. Bacterial species within these could not be identified and biofilm was not observed. Using FISH with CLSM, bacteria were seen in 15 of the 17 otitis media mucosal specimens. In this group, 11 (65% of the 17 middle ear mucosal biopsies showed evidence of bacterial biofilm and 12 demonstrated intracellular bacteria. 52% of biopsies were positive for both biofilm and intracellular bacteria. At least one otopathogen was identified in 13 of the 15 samples where bacteria were present. No differences were observed between biopsies from children with COME and those with rAOM. Conclusion Using FISH and CLSM, bacterial biofilm and intracellular infection with known otopathogens are demonstrated on/in the middle ear mucosa of children with COME and/or rAOM. While their role in disease pathogenesis remains to be

    Full Text Available 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.

    Full Text Available Introduction: Chronic otitis media (COM, a persistent and durable inflammation and infection of the middle ear, is a common disorder. Alterations in the contralateral ear in sufferers have been observed in recent years. Because only a few studies have been reported in this area, we performed this study in order to assess alterations in the contralateral ear of patients with COM.   Materials and Methods: Cross-sectional and descriptive methods were used in 100 patients with COM who were selected for surgical treatment and admitted to hospital. An information form was completed for all patients including demographic data, medical history of otoscopy and paraclinical examinations such as pure tone audiometry (PTA, tympanometry, Schuller radiography, and high resolution computed tomography (HRCT. All data were processed using SPSS (version 18 software and descriptive statistical tests.   Results: According to otoscopy, PTA, tympanometry and graphical analysis, 60% of patients experienced disorders of the contralateral ear. Otoscopy analysis showed 54% of patients had a disorder of the contralateral ear, with the most common disorder being perforation of the ear drum. PTA showed a 48% incidence of contralateral ear problems (85% conductive hearing impairment; 12.5% sensorineural hearing impairment; 1.2% mixed. A total of 73.2% of patients with conductive hearing loss had a problem across all frequencies, while half of the patients with sensorineural hearing impairment had problems at frequencies greater than 1000 Hz. According to tympanometry, 38% of patients had problem in the contralateral ear. HRCT and Schuller graphical analyses indicated 31.5% and 36% occurrence of contralateral ear disorders, respectively.   Conclusion:  More than 50% of patients with COM in one ear have a chance of also presenting with the disease in the other ear. Outcomes of this study and previous studies have shown that COM should not be perceived as a disease limited

    Full Text Available Objective: Chronic suppurative otitis media (CSOM can lead to dreadful and fatal complications. Objective of my study is an assessment of factors leading to the development of CSOM complications in different age groups and which age group is more prone to the development of complications. And to find out most frequent complication occurring in the target population. Introduction: CSOM is a long standing infection of a part or whole of the middle ear cleft characterized by ear discharge and a permanent perforation. It affects both sexes and all age groups. Pathways of spread of infection: Direct bone erosion, venous thrombophlebitis, preformed pathways. Classification of complications: Intracranial - Mastoiditis, facial paralysis, labrynthitis, petrositis. Extracranial - Meningitis, extradural abscess, subdural abscess, brain abscess, lateral sinus thrombophlebitis, otitic hydrocephalus. Development of complications depends upon; organism′s virulence, poor resistance of the patient, systemic disease, resistance to antibiotics, poor socioeconomic status, lack of awareness about healthcare, lack of availability of trained specialist. Materials and Methods: A descriptive cross-sectional study was carried out from 2008 to 2013 in ENT Head and Neck Surgery Department, Jinnah Postgraduate Medical Centre, Karachi. Record of 65 patients was selected through nonprobability convenient sampling; sample was divided into two groups according to age Group A 10-18 years and Group B 18-45 years.

    Full Text Available BACKGROUND: Pharyngeal bacteria are exposed to different sugar conditions depending on the diet of the child. We hypothesized that dietary factors such as daily intake of carbohydrates could be associated with pneumococcal carriage and the occurrence of otitis media in children. METHODS: Our study design was a cross-sectional study among 1006 children attending child day care centers. Parents filled in a food frequency questionnaire. Oropharyngeal swabs were collected from each child. The primary outcome was the occurrence of pneumococcal carriage and the secondary outcome the number of acute otitis media episodes during life. Principal component analysis was used to group dietary intake into nine factors. The models were adjusted for age, gender of the child and educational level of the mother. RESULTS: The dietary factor which included high consumption of sweet pastries and jam was associated with an increased risk of pneumococcal carriage (OR 1.17, 95% CI 1.01 to 1.36, P-value 0.04. The factor including frequent consumption of fruit and berries was associated with a decreased risk of acute otitis (regression coefficient -0.51, 95% CI -0.98 to -0.03, P=0.04. A high intake of consumption of sweets and snacks (OR 1.36, 95% CI 1.03 to 1.80, P=0.03 was associated with an increased risk of caries. CONCLUSIONS: Diet was associated with a risk of pneumococcal carriage and the occurrence of otitis media. Diet may thus be a modifiable risk factor for the occurrence of acute otitis media.

    Johanna Nokso-Koivisto

    Full Text Available BACKGROUND: Acute otitis media (OM is a common disease which often develops through complex interactions between the host, the pathogen and environmental factors. We studied single nucleotide polymorphisms (SNPs of genes involved in innate and adaptive immunity, and other host and environmental factors for their role in OM. METHODS: Using Sequenom Massarray platform, 21 SNPs were studied in 653 children from prospective (n = 202 and retrospective (n = 451 cohorts. Data were analyzed for the relationship between SNPs and upper respiratory infection (URI frequency, risk of acute OM during URI episodes, and proneness to recurrent OM. RESULTS: Increased risk for OM proneness was associated with CX3CR1 (Thr280Met SNP and with a jointly interactive group of IL-10 (-1082 SNP, IL-1β (-511 wild type genotype and white race. Family history of OM proneness independently increased the risk for frequent URIs, OM occurrence during URI, and OM proneness. Additionally, IL-1β (-31 SNP was associated with increased risk for frequent URIs, but IL-10 (-592, IL-1β (-511, IL-5 (-746 and IL-8 (-251 SNPs were associated with decreased risk of URI. CONCLUSION: IL-1β (-31, CX3CR1 (Thr280Met, IL-10 (-1082 and IL-1β (-511 SNPs were associated with increased risk for frequent URIs or OM proneness.

  9. Assessment of senses of hearing and balance in chronic suppurative otitis media

    Full Text Available Chronic suppurative otitis media is among the most frequent illnesses treated in ENT wards. To establish the diagnosis, otomicroscopy alone usually suffice. Assessing the sense of hearing, often the sense of balance, too, is mandatory. Assessment of hearing will show the extent of conductive and sensorineural hearing loss. Apart from this, sometimes, when the finding is not obvious, it is necessary to conduct audiological investigation in more detail in order to establish whether the diagnosis of chronic suppurative otitis media is correct. Existence and extent of conductive hearing loss or confIrmation of tympanic membrane perforation by tympanometry can help a great deal. Also, some new results about the site of perforation and the middle ear volume influence on conductive hearing loss may help have a better insight into chronic suppurative otitis media. Assessing the sense of balance may show dysfunctions with not yet necessarily permanent damage: perilymphatic fistula and benign paroxysmal positional vertigo (BPPV. Unilateral or bilateral damage may be diagnosed with appropriate tests of vestibuloocular reflex (VOR: spontaneous nystagmus, head impulse test, head shaking test. These bedside tests do not require bulky, expensive equipment for stimulus delivery or special equipment for recording nystagmus. In addition, their significance is their ability to provide enough information without performing caloric testing which is contraindicated in chronic suppurative otitis media.

    Acute otitis media (AOM) is the most common childhood infection caused by bacteria. The pathogenesis of AOM implicates initial adherence of a pathogen to the nasopharyngeal epithelium, which is followed by bacterial colonization of the middle ear cavity through the Eustachian tube. N......-acetylgalactosamine (GalNAc) is an important constituent of mucins and GalNAc containing sugar residues seem to be essential for initial adherence of respiratory bacteria to the surface of epithelial cells....

    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.

    Full Text Available Abstract Background Aboriginal children in remote Australia have high rates of complicated middle ear disease associated with Streptococcus pneumoniae and other pathogens. We assessed the effectiveness of pneumococcal vaccination for prevention of otitis media in this setting. Methods We compared two birth cohorts, one enrolled before (1996–2001, and the second enrolled after introduction of 7-valent pneumococcal conjugate and booster 23-valent polysaccharide vaccine (2001–2004. Source populations were the same for both cohorts. Detailed examinations including tympanometry, video-recorded pneumatic otoscopy and collection of discharge from tympanic membrane perforations, were performed as soon as possible after birth and then at regular intervals until 24 months of life. Analyses (survival, point prevalence and incidence were adjusted for confounding factors and repeated measures with sensitivity analyses of differential follow-up. Results Ninety-seven vaccinees and 51 comparison participants were enrolled. By age 6 months, 96% (81/84 of vaccinees and 100% (41/41 of comparison subjects experienced otitis media with effusion (OME, and by 12 months 89% and 88% experienced acute otitis media (AOM, 34% and 35% experienced tympanic membrane perforation (TMP and 14% and 23% experienced chronic suppurative otitis media (CSOM. Age at the first episode of OME, AOM, TMP and CSOM was not significantly different between the two groups. Adjusted incidence of AOM (incidence rate ratio: 0.88 [95% confidence interval (CI: 0.69–1.13] and TMP (incidence rate ratio: 0.63 [0.36–1.11] was not significantly reduced in vaccinees. Vaccinees experienced less recurrent TMP, 9% (8/95 versus 22% (11/51, (odds ratio: 0.33 [0.11–1.00]. Conclusion Results of this study should be interpreted with caution due to potential bias and confounding. It appears that introduction of pneumococcal vaccination among Aboriginal infants was not associated with significant changes

    Otitis media (OM), inflammation of the middle ear, remains the most common cause of hearing impairment in children. It is also the most common cause of surgery in children in the developed world. There is evidence from studies of the human population and mouse models that there is a significant genetic component predisposing to OM, yet nothing is known about the underlying genetic pathways involved in humans. We identified an N-ethyl-N-nitrosourea-induced dominant mouse mutant Junbo with hearing loss due to chronic suppurative OM and otorrhea. This develops from acute OM that arises spontaneously in the postnatal period, with the age of onset and early severity dependent on the microbiological status of the mice and their air quality. We have identified the causal mutation, a missense change in the C-terminal zinc finger region of the transcription factor Evi1. This protein is expressed in middle ear basal epithelial cells, fibroblasts, and neutrophil leukocytes at postnatal day 13 and 21 when inflammatory changes are underway. The identification and characterization of the Junbo mutant elaborates a novel role for Evi1 in mammalian disease and implicates a new pathway in genetic predisposition to OM.

    Full Text Available Background. It is unclear if clinicians evaluate for concurrent bacteremia or UTI in young patients diagnosed with acute otitis media (AOM. Objectives. To describe how often, and under which circumstances, emergency providers investigate for bacteremia or UTI in 2–36 month olds with AOM. Methods. Cases of AOM were analyzed from the 2001–2004 National Hospital Ambulatory Medical Care Survey (NHAMCS-Emergency Department dataset. Results. AOM was diagnosed in 17% of the 10,847 recorded visits of 2–36 month olds. Of these visits, laboratory testing included: CBC: 7%, Blood culture: 4%, urinalysis or urine culture: 5%, and any of these tests: 9%. Rates of testing for 2–6 month olds with temperature ≥ 38.0 (CBC: 13%, blood culture: 9%, urinalysis or urine culture: 7%, any of the tests: 14% were not significantly different from testing of patients aged 6–12 months, or 12–36 months (all P>.1. Patients with temperature of ≥39.0 were more likely to have all tests, with the exception of urine investigation, than patients with temperature between 38.0 and 38.9. Conclusions. 17% of 2–36 month old patients seen in the emergency department are diagnosed with AOM. Investigating for bacteremia or UTI in these patients is not routine, even in febrile infants.

    Marie S Rye

    Full Text Available BACKGROUND: Otitis media (OM is a common childhood disease characterised by middle ear inflammation and effusion. Susceptibility to recurrent acute OM (rAOM; ≥ 3 episodes of AOM in 6 months and chronic OM with effusion (COME; MEE ≥ 3 months is 40-70% heritable. Few underlying genes have been identified to date, and no genome-wide association study (GWAS of OM has been reported. METHODS AND FINDINGS: Data for 2,524,817 single nucleotide polymorphisms (SNPs; 535,544 quality-controlled SNPs genotyped by Illumina 660W-Quad; 1,989,273 by imputation were analysed for association with OM in 416 cases and 1,075 controls from the Western Australian Pregnancy Cohort (Raine Study. Logistic regression analyses under an additive model undertaken in GenABEL/ProbABEL adjusting for population substructure using principal components identified SNPs at CAPN14 (rs6755194: OR = 1.90; 95%CI 1.47-2.45; P(adj-PCA = 8.3 × 10(-7 on chromosome 2p23.1 as the top hit, with independent effects (rs1862981: OR = 1.60; 95%CI 1.29-1.99; P(adj-PCA = 2.2 × 10(-5 observed at the adjacent GALNT14 gene. In a gene-based analysis in VEGAS, BPIFA3 (P(Gene = 2 × 10(-5 and BPIFA1 (P(Gene = 1.07 × 10(-4 in the BPIFA gene cluster on chromosome 20q11.21 were the top hits. In all, 32 genomic regions show evidence of association (P(adj-PCA<10(-5 in this GWAS, with pathway analysis showing a connection between top candidates and the TGFβ pathway. However, top and tag-SNP analysis for seven selected candidate genes in this pathway did not replicate in 645 families (793 affected individuals from the Western Australian Family Study of Otitis Media (WAFSOM. Lack of replication may be explained by sample size, difference in OM disease severity between primary and replication cohorts or due to type I error in the primary GWAS. CONCLUSIONS: This first discovery GWAS for an OM phenotype has identified CAPN14 and GALNT14 on chromosome 2p23.1 and the BPIFA gene cluster on chromosome 20q11.21 as

    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.

    Introducción: la otitis media aguda es una inflamación del oído medio frecuente en la edad pediátrica. Aproximadamente 2 % de todos los casos desarrolla complicaciones intracraneales, más específicamente meningitis; por lo general, los infartos cerebrales originados por esta última son venosos. Rara vez se ha descrito la ocurrencia de un infarto arterial cerebral como complicación directa de la otitis media aguda. Caso clínico: niña de 12 meses de edad quien fue llevada a un servicio de urgencias por síndrome febril secundario a otitis media aguda y alteración del estado de conciencia. A la exploración física se identificó que estaba somnolienta, con anisocoria, midriasis en el ojo derecho y hemiparesia izquierda. Con la tomografía axial computarizada de cerebro se apreció un infarto arterial cerebral extenso. Los padres no autorizaron la craniectomía descompresiva y la paciente falleció a las 48 horas de su ingreso hospitalario. Conclusiones: a pesar de los recursos tecnológicos con los que se dispone actualmente, el infarto cerebral relacionado con la otitis media aguda tiene una evolución tórpida. Los signos neurológicos focalizadores y el deterioro progresivo deben apuntar a la ineficacia del tratamiento antimicrobiano instaurado.

  9. Otitis media in a new mouse model for CHARGE syndrome with a deletion in the Chd7 gene.

    Directory of Open Access Journals (Sweden)

    Cong Tian

    Full Text Available 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.

    Full Text Available Debido a que la otitis media aguda, es la primera causa de uso de antibióticos en la edad pediátrica, es importante lograr una utilización adecuada y racional de los antibióticos en estas patologías, siendo imprescindible que antes de iniciar un tratamiento antimicrobiano se haga un buen diagnóstico clínico y se conozca el patrón microbiológico y de susceptibilidad antimicrobiana prevaleciente. La presente revisión incorpora conceptos novedosos para seleccionar la terapia antimicrobiana en niños con otitis media, tomando en cuenta principios farmacocinéticos y farmacodinámicos aplicados a conceptos microbiológicos. Estos nuevos conceptos han revolucionado el tratamiento de diversos procesos infecciosos en pediatría y superan los criterios, un poco más simples, en los que se define únicamente si una bacteria es sensible o resistente a un determinado antibiótico, incorporando aspectos fundamentarles como lo son la biodisponibilidad, la penetración del antimicrobiano al oído medio, la dosis recomendada y los intervalos entre cada dosificación.Because acute respiratory infections and particularly acute otitis media (AOM, are the most common cause of antimicrobial prescription in pediatric patients, it is important to optimize antimicrobial therapies. It is essential that before prescribing an antimicrobial agent, the AOM diagnosis is well established and the local microbiological pattern is known. The present review incorporates novel concepts for the selection of the antimicrobial therapy in children with AOM taking into account pharmacokinetic and pharmacodynamic principles applied to microbiologycal concepts. These new concepts have revolutionized the treatment of diverse infectious diseases in pediatric patients and particularly in the treatment of children with otitis media.

    The variability in the recovery of otitis media (OM) is not well understood. Recent data have shown a critical role for toll-like receptors (TLRs) in inflammatory responses to bacteria. It remains unclear whether TLRs-mediated mucosal immunity plays a role in the OM recovery. The etiology, pathological profile, expression levels of TLR2, TLR4, TLR5, TLR9 and proinflammatory cytokines were measured in human middle-ear mucosae sampled from three subject groups: non-OM group, chronic otitis-media (COM) group, and chronic suppurative otitis-media (CSOM) group. Of the 72 ears, 86.11% CSOM patients were positive for bacteria. The cellular makeup of the middle ear mucosa differs among the three groups. Mucosae from the CSOM group presented chronic inflammation or suppurative inflammation in the rudimentary stroma, mainly with infiltration of monocytes and macrophages. The mRNA and protein levels of TLR2, TLR4, and TLR5 exhibited no difference between the non-OM and COM groups but were significantly lower in the CSOM group. Conversely, there was no significant difference in the TLR9 level among the three groups. Furthermore, proinflammatory cytokines TNF-α, IL-1β, IFN-γ, IL-6 were up-regulated in the CSOM group. This study provides evidence that the variability in clinical otitis media recovery might be associated with the variability in the expression of mucosal TLRs. Reduced TLR levels in the middle-ear mucosa might cause weak host response to bacteria, persistent inflammation and susceptibility to CSOM.

    Biofilms are organized bacterial communities that may be homogeneous or heterogeneous. They play a significant role in the pathogenesis of chronic nasal sinusitis, chronic tonsillitis, cholesteatomas, and device-related infections. Despite this, few studies have been done that examine the presence of bacterial biofilms in tissues from patients with different types of COM or middle ear cholesteatomas. In the current study, we examined the presence of biofilms in surgical tissue specimens from humans with chronic ear infections using scanning electron microscopy (SEM). We hypothesize that bacterial biofilms present differently in patients with different types of chronic otitis media. Our results provide new insights regarding treatment of chronic otitis media. A prospective study was conducted in which middle ear tissues were obtained from 38 patients who underwent tympanoplasty and/or tympanomastoid surgery due to chronic ear infections. A total of 50 middle and mastoid tissue samples were processed for SEM analysis. In addition, 38 middle ear secretion specimens were obtained for routine bacterial culture analysis. Bacterial biofilms were present in 85 % (11 of 13) of patients with middle ear cholesteatoma, 92 % (12/13) of patients with chronic otitis suppurative media (CSOM), and 16 % of patients (2/12) with tympanic membrane perforation (TMP). Fungal biofilms were found in two cases of cholesteatoma. The positive coincidence rate between bacterial biofilms visualized by SEM and bacteria detected by culture was 82 %. Our findings suggest that bacterial biofilms are very common in CSOM and middle ear cholesteatomas. Positive bacterial cultures imply the presence of biofilm formation in CSOM and cholesteatomas. As such, our results provide new insights regarding treatment of chronic otitis media.

    A 29 year-old Nigerian studying in the UK presented with a neck lump and otitis media. Paragonimus-like trematode eggs were found in the neck lump aspirate. Morphologically these eggs resembled Paragonimus uterobilateralis or Achillurbainia congolensis. We favoured the diagnosis of achillurbainiasis over extrapulmonary paragonimiasis on the basis of clinical features and because we could not amplify DNA sequences using PCR primers specific for Paragonimus species. We discuss current diagnostic challenges for this rare parasitic infection.

    Background: Otitis media can lead to severe health consequences, and is the most common reason for antibiotic prescriptions and biofilm-mediated infections. However, the increased pattern of drug resistance in biofilm forming bacteria complicates the treatment of such infections. Objectives: This study was aimed to estimate the biofilm formation potential of the clinical isolates of otitis media, and to evaluate the efficacy of antibiotics and plant extracts as alternative therapeutic agents in biofilm eradication. Materials and Methods: The ear swab samples collected from the otitis media patients visiting the Mayo Hospital in Lahore were processed to isolate the bacteria, which were characterized using morphological, biochemical, and molecular (16S rRNA ribotyping) techniques. Then, the minimum inhibitory concentrations (MICs) of the antibiotics and crude plant extracts were measured against the isolates. The cell surface hydrophobicity and biofilm formation potential were determined, both qualitatively and quantitatively, with and without antibiotics. Finally, the molecular characterization of the biofilm forming proteins was done by amplifying the ica operon. Results: Pseudomonas aeruginosa (KC417303-05), Staphylococcus hemolyticus (KC417306), and Staphylococcus hominis (KC417307) were isolated from the otitis media specimens. Among the crude plant extracts, Acacia arabica showed significant antibacterial characteristics (MIC up to 13 mg/ml), while these isolates exhibited sensitivity towards ciprofloxacin (MIC 0.2 µg/mL). All of the bacterial strains had hydrophobic cellular surfaces that helped in their adherence to abiotic surfaces, leading to strong biofilm formation potential (up to 7 days). Furthermore, the icaC gene encoding polysaccharide intercellular adhesion protein was amplified from S. hemolyticus. Conclusions: The bacterial isolates exhibited strong biofilm formation potential, while the extracts of Acacia arabica significantly inhibited biofilm

    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.

    Full Text Available Pharyngotonsillitis (FT and acute otitis media (OMA are among the most frequent infectious diseases of the childhood and exact a heavy toll on the Italian national health service (INHS, families and society as a whole. In case of established or suspected bacterial origin, current treatment guidelines for FT recommend 5-10 days of oral antibiotics, chosen among available penicillins, cephalosporins, or macrolides. More controversial appears the systematical use of an antibiotic for OMAs, but prevalent expert opinion suggests use of the same agents. In this paper, an economical appraisal of five of the most prescribed oral antibiotics for these indications in Italy (cefaclor, amoxicyllin, amoxicyllin/clavulanate, clarithromycin and azithromycin is provided. The evaluation was conducted through the development and implementation of two distinct models, constructed to reflect national treatment patterns of these infections. Clinical and economical data were obtained from several sources: literature review, including published meta-analyses, consultation of an expert panel and, most importantly, from the results of a specific questionnaire-based survey completed by 136 pediatricians, based throughout Italy. The models were run to conduct both cost-effectiveness and cost-minimization analyses, that consistently indicated cefaclor and amoxicyllin to be substantially equivalent in terms of total costs to the INHS and the Italian society, but significantly more convenient than amoxicyllin/clavulanate, claritrhomycin or azithromycin. Extensive probabilistic sensitivity analyses confirmed the robustness of this conclusion.

    1997-07-01

    In a prospective observational study carried out by 1 homoeopathic and 4 conventional ENT practitioners, the 2 methods of treating acute pediatric otitis media were compared. Group A received treatment with homoeopathic single remedies (Aconitum napellus, Apis mellifica, Belladonna, Capsicum, Chamomilla, Kalium bichromicum, Lachesis, Lycopodium, Mercurius solubilis, Okoubaka, Pulsatilla, Silicea), whereas group B received nasal drops, antibiotics, secretolytics and/or antipyretics. The main outcome measures were duration of pain, duration of fever, and the number of recurrences after 1 year, whereby alpha < 0.05 was taken as significance level. The secondary measures were improvement after 3 hours, results of audiometry and tympanometry, and necessity for additional therapy. These parameters were only considered descriptively. The study involved 103 children in group A and 28 children in group B, aged between 6 months and 11 years in both groups. For duration of pain, the median was 2 days in group A and 3 days in group B. For duration of therapy, the median was 4 days in group A and 10 days in group B: this is due to the fact that antibiotics are usually administered over a period of 8-10 days, whereas homoeopathics can be discontinued at an earlier stage once healing has started. Of the children treated, 70.7% were free of recurrence within a year in group A and 29.3% were found to have a maximum of 3 recurrences. In group B, 56.5% were free of recurrence, and 43.5% had a maximum of 6 recurrences. Out of the 103 children in group A, 5 subsequently received antibiotics, though homoeopathic treatment was carried through to the healing stage in the remaining 98. No permanent sequels were observed in either group.

Furthermore, gastroesophageal reflux (GER) has been associated with a variety of upper aerodigestive tract symptoms or diseases, such as sinusitis, laryngitis, and otits. The objective of the present study was to determine the frequency of GER in children, aged 3 months to 7 years, with OM. Materials and Methods: This retrospective case-control study was conducted on 50 children with OM and 50 healthy children. Presence of GER as the main variables was diagnosed by clinical examination in all studied children using the questionnaires with 2 age-stratified versions of the pediatric GER disease symptoms for children 2 years old and younger, and children 3–7 years old. Results: The prevalence of GER in children with OM and controls was 58% and 22% respectively (P = 0.0005). The frequency of irritability, congestion, and feeding complex in children with OM were significantly more than in control groups. Among children with recurrent acute OM (AOM), and chronic serous OM (CSOM) the prevalence of GER was significantly more than controls (61.1%, vs. 22% for AOM, P = 0.004, and 72.7% vs. 22%, P= 0.003). In children with AOM, regurgitation, vomiting, irritability and congestion were significantly higher than controls included. In children with CSOM, regurgitation, vomiting, and congestion were significantly higher than controls. Conclusion: Results show a significant association between GER and OM, AOM and CSOM in children with OM compares to healthy children. This shows that looking for GER in children with OM may help improving treatments outcomes. PMID:27274496

    Objectives. Determine the influence of the acute otitis externa clinical practice guideline on clinical care. Study Design. Cross-sectional study with historical controls. Setting. Outpatient departments in the United States. Methods. Cases of acute otitis externa occurring in 2004-2005 (before guideline publication) and 2007-2008 (after guideline publication) were extracted from the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Care Survey. Prescribing rates for ototopical medications, analgesic recommendations, and oral antibiotics were determined and compared before and after guideline publication and relative to guideline recommendations. Results. An estimated 5.50 (standard error of the estimated mean, 0.38) million visits (mean age, 27.7 [1.7] years; 49.8% male) with a primary and singular coded diagnosis of acute otitis externa were studied (2.64 [0.26] million visits for 2004-2005 and 2.86 [0.28] million visits for 2007-2008). Prescribing rates for ototopical preparations were 67.2% (5.3%) and 67.6% (5.0%) before and after guideline publication, respectively (P = .955). Recommendation rates for analgesics were 14.2% (3.3%) and 20.6% (3.9%), respectively (P = .248). Prescription rates for oral antibiotics were 21.7% (4.8%) and 30.5% (3.6%), before and after, respectively (P = .166). Conclusion. Clinician behavior in the medical treatment of acute otitis externa has not significantly changed after guideline publication, despite clear, evidence-based guideline recommendations. These data have important implications for performance measures based on the guideline. Further efforts toward guideline dissemination are likely needed.

    The role of Corynebacterium spp. in the pathogenesis of canine and feline otitis externa/media and their appropriate antimicrobial therapy are unclear. The objectives of this study were to (1) better establish the pathogenicity of Corynebacterium spp. in otitis utilizing reported criteria and by assessing clinical response to antibiotic therapy and (2) to determine the antimicrobial susceptibility patterns of Corynebacterium spp. associated with otitis. The study was retrospective, targeting cultures positive for Corynebacterium spp. Corynebacterium spp. were part of mixed microbial populations in 79/81 cultures. Corynebacterium spp. pathogenicity was highly questionable because of their almost invariable presence with other microbes and the observation that Corynebacterium spp. usually disappear from the ear with resolution of other infections, even when the Corynebacterium spp. are resistant to the prescribed antibiotic(s). However, 2/81 cultures came from two canine ears wherein Corynebacterium spp. may have been pathogenic. Antimicrobial sensitivities for Corynebacterium spp. were available for 54 isolates. Most isolates were susceptible to chloramphenicol (53/54), amikacin (50/54), tetracycline (50/54), gentamicin (46/54), and enrofloxacin (32/54). Among those antibiotics available in otic products, gentamicin and enrofloxacin would be rational choices for the empirical, topical therapy of Corynebacterium spp.

    Acute otitis externa (AOE) is most often infectious in origin, and can be easily treated with a combination of topical antibiotic and steroid preparations. Systemic antibiotics are rarely needed for AOE. Chronic otitis externa (COE) can be more difficult to treat, but if an underlying cause can be identified this condition can often be successfully managed. In both AOE and COE, prevention is fundamental. If patients are able to avoid precipitating factors, future episodes can often be averted.

    Studies of microorganisms involved in otitis media in children often use a nasopharyngeal sample as a proxy for the middle ear fluid to test for bacteria and viruses. The question is whether such studies provide an accurate estimate of the prevalence of microorganisms involved in otitis media. We performed a systematic review of the literature reporting on the concordance between test results of nasopharyngeal and middle ear fluid samples for the most prevalent microorganisms in children with otitis media. Our findings show that the concordances vary from 68% to 97% per microorganism. For the most prevalent microbes, positive predictive values are around 50%. Most negative predictive values are moderate to high, with a range from 68% up to 97%. These results indicate that test results from nasopharyngeal samples do not always provide an accurate proxy for those of the middle ear fluid. It is important to interpret and use results of such studies carefully.

    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.

    Summary: To investigate the etiology and pathogenesis of cholesteatoma otitis media accompanied by cholesterol granuloma and the relationship between cholesteatoma and cholesterol granuloma, 63 cas-es of middle ear cholesterol granuloma treated in our hospital during the period from March 1988 to May 2000 were retrospectively reviewed. All cases were surgically and pathologically verified. 15 cas-es of cholesteatoma coexisting with cholesterol granuloma were found among the 63 patients. All 15 cases had a long-term history of otitis media, such as otorrhea (sanguine purulent otorrhea and blood-y otorrhea in 8 cases) and perforation of the eardrum (perforation of pars flaccida in 8 cases). Tem poral bone CT scans showed cholesteatoma in 11 cases. All patients were treated surgically, and cholesteatoma and cholesterol granuloma were found coexisting alternately, the latter lying mainly in the tympanic antrum, attic and mastoid air cells. Chocolate-colored mucus was accumulated in well developed mastoid air cells, and glistening dotty cholesterol crystals were also found. In most cases,enlarged aditus, destruction of lateral attic wall, erosion of ossicular chain, exposure of horizontal segment of facial nerve and tegmen of attic were observed. Occlusion of Eustachian tube was noted in 6 cases, and occlusion of tympanic isthmus was revealed in all cases. A post-operative dry ear was achieved in all patients, and hearing improvement was achieved in all 12 cases following tympanoplas-ty. Cholesteatoma and cholesterol granuloma in middle ear may share a common pathophysiological e-tiology: occlusion of ventilation and disturbance of drainage. The diagnosis should be considered when patients presented with chronic otitis media with bloody otorrhea. CT and magnetic resonance imaging are useful for the diagnosis before operation. The surgical approach depends on the location,extension and severity of the lesion, The purpose of surgery is to remove the lesion and create an

    Full Text Available Background The aim of this study was to assess the prevalence of hospitalisation for otitis media across the different risk indicators for Western Australian children (less than 15 years old over a 10-year period. Method This retrospective population-based study used the deidentified detailed data of children under the age of 15 years, hospitalised for otitis media (OM, as determined by principal diagnosis (ICD-10AM and obtained from the Western Australian (WA Hospital Morbidity Dataset for 10 financial years from 1999–2000 to 2008–2009. Various risk indicators, including age, gender, Indigenous status, insurance status, hospital area, hospital type, and length of stay were also analysed. Results Out of 26,294 cases of in-hospital care, Indigenous children comprised 4.7 per cent (n=1,226, while the non-Indigenous children comprised 95.3 per cent (n=25,068. The majority of the children, nearly 98.8 per cent, were admitted for chronic OM. The children were grouped into three age groups, namely, 0–4 years, 5–9 years, and 10–14 years. Nearly two-thirds of all cases were in the 0–4-year age group. Significantly more non-Indigenous (51 per cent than Indigenous children (2 per cent had private health insurance. The hospitalisation rates were directly proportional between the number of Indigenous children living in the area and the increasing remoteness of the area along with greater socioeconomic disadvantage. There were 24 per cent more cases from very remote areas compared to highly accessible areas, and there were 60 per cent more cases from the most disadvantaged socioeconomic category, compared with the least disadvantaged category, for Indigenous children. Conclusion These data depict the variations in prevalence of otitis media hospitalisations within the community, as affected by various risk indicators.

    Full Text Available INTRODUCTION: Chronic Suppurative otitis media (CSOM is the most common condition encountered by otolaryngologists in day to day practice. The importance of chronic otitis media lies in its dreaded complications and deafness. AIM: This study was under taken to identify the microbiological isolates of the ear discharge in CSOM cases and their sensitivity to antibiotics. SETTINGS AND DESIGN: Tertiary care hospital in north costal Andhra Pradesh. It was a Prospective study. MATERIALS & METHODS: About 100 patients having ear discharge who attended ENT outpatient department from July 2013 to Feb 2014 for a period of 8months were studied. Aural swabs were sent to microbiology lab for culture &sensitivity. RESULTS: Culture reports showed aerobic bacterial isolates in 85 cases, fungi in 7 cases and sterile in 8 cases. Of the 85 cases of aerobic bacteria, staphylococcus aureus was isolated in 34 cases (40% followed by Pseudomonas aeruginosa in 29 cases (34%, klebsiella in 16 cases (18.8%, E.coli in 4 cases (4.7% and proteus in 2 cases. Antibiotic sensitivity reports showed Staphylococcus was more susceptible to netilmycin (97%, amoxiclav (91.7% and least sensitive to ceftazidime (64.7%. Pseudomonas was more sensitive to amikacin (96.5%, gentamycin (93.1% and least sensitive to amoxyclav (79.3%, ampicillin + sulbactum (82.75%. CONCLUSION: Mono microbial etiology, especially Staphylococcus species was found to be the most common organism causing chronic otitis media. Knowledge of the prevailing flora and their susceptibility to antimicrobials will guide the clinicians for early and effective treatment thereby avoiding complications.

    Background Otitis media with effusion (OME) is a disease with complicated pathogeneses which are not clearly known. Increasing interest has been focused on immunological cells, cytokines and their roles in chronic inflammatory states. This study was designed to disclose the existence and roles of interleukin-10 (IL-10) and transforming growth factor beta1 (TGF-β1) in the cause of OME in adults, and to investigate the probable role of Foxp3+CD4+CD25+ T cells in OME.Methods The concentrations of IL-10 and TGF-β1 in the middle ear effusions (MEEs) and plasmas of 36 adults (45 ears) with OME were measured by means of enzyme linked immunosorbent assay (ELISA). As contrast, the concentrations of IL-10 and TGF-β1 in the plasma of 30 normal volunteers were measured using the same method. Furthermore, the proportion of Foxp3+CD4+CD25+ T cells in CD4+ T cells of blood was tested by flow cytometry. Results (1) The concentrations of IL-10 in all MEEs and plasmas of the chronic OME patients were higher than those in patients with acute OME (both P 0.05). The concentration of IL-10 in MEEs had a strong correlation with the duration of the illness (r=0.547, P<0.01). The same correlation was also found between the concentration of TGF-β1 in MEEs and the times patients being treated (r=0.579, P <0.01). (3) The proportion of Foxp3+CD4+CD25+T/CD4+ T cells in the blood of chronic OME was not only significantly higher than that in the acute OME (P<0.01), but also higher than that in normal volunteers (P <0.01). In chronic OME, there was a correlation between the proportion of Foxp3+CD4+CD25+ T/CD4+ T cells in the blood and the concentration of IL-10 in the plasmas (r=0.602, P <0.05). Conclusions IL-10 and TGF-β1, as two important immunoregulatory mediators, participate in middle ear inflammatory response, especially in chronic course of OME in adults. Foxp3+CD4+CD25+ T cells may play some immunoregulatory roles in the course of this disease.

    Tuberculous otitis media is a rare disease, hence not often considered in the differential diagnosis of otorrhea. This results in late diagnosis with resulting complications such as irreversible hearing loss. A case report with review of the literature is presented, emphasizing that tuberculosis should be considered in the differential diagnosis of otorrhea not responding to commonly prescribed antibiotics. We also emphasize the importance of awareness creation in the management of such a disease, involving family members to oversee treatment and also research on ways of shortening duration of treatment to avoid default in treatment.

    Cochlear implantation in the setting of chronic otitis media or previous middle ear surgery poses several problems for the surgeon: possible spread of infection to the cochlea and the subarachnoid spaces with consequent meningitis, risk of electrode array extrusion and possible recurrence of the original disease. Several surgical strategies have been proposed to overcome these problems. In the present study, clinical and functional results of cochlear implantation in 26 patients with chronic otitis media (8 cases) or previous middle ear surgery (18 cases) in the ear most suitable for implantation were retrospectively reviewed. Among the 8 patients with chronic otitis media, in 7 cases a subtotal petrosectomy associated with external auditory canal closure and mastoid and Eustachian tube obliteration was performed, while in the remaining patient cochlear implantation was done 6 months after a myringoplasty. The only complication observed was a reperforation of the tympanic membrane in this latter patient. Among the 18 patients with previous middle ear surgery, 2 had undergone intact canal wall tympanomastoidectomy and were implanted utilising the previous surgical approach. In the remaining 16 patients who had a radical cavity, an open technique was maintained in 3 cases; a cavity revision associated to external auditory canal closure, Eustachian tube and mastoid obliteration was performed in 12 patients, while in one case a middle cranial fossa approach was utilised. Two of the 3 patients in whom an open technique was maintained have experienced electrode array extrusion. The only complication observed in the remaining patients was the breakdown of the external auditory canal closure in one case. No problems were noted in patients who had undergone intact canal wall tympanomastoidectomy as well as in the subject implanted via the middle cranial fossa approach. All patients achieved and maintained good hearing performance over time. Subtotal petrosectomy associated

    Inadvertent retention of surgical gauze during an operation can have disastrous consequences for both the patient and the surgeon. Several cases have been reported, particularly after abdominal surgery. However, it has never to our knowledge been reported as a leading cause of dysfunction of the Eustachian tube after orthognathic surgery. We recently encountered a patient in whom it presented with unilateral otitis media with an effusion after orthognathic surgery. All surgeons involved with orthognathic surgery should be aware that remnants of surgical gauze after orthognathic surgery can compromise the Eustachian tube and cause otitis media with an effusion.

    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 health perception (p social functioning (p 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.

    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 the 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.

    Cochlear implants (CI) candidates with chronic otitis media require special attention and management. The need of opening of the inner ear creates potential routes of spread of infection to subarachnoid spaces and lead to meningitis. The aim of the study was to analyse the technique and complications of subtotal petrosectomy (SP) in cochlear implant candidates with chronic otitis media at three different CI centres. A retrospective study was carried out in three Territory Referral Hospitals. The centres follow Fisch's philosophy and surgical techniques of SP. The study group consisted of 19 patients, 4 men and 15 women, aged 12-82 years. All patients underwent SP with either primary or staged CI implantation. Indications for single or a staged management, difficulties during surgery and complications were analysed. Skin and muscle flap design in primary and revision cases as well as imaging follow-up strategy are discussed. In 14 patients implantation was performed in a single stage and in 5 cases in two stages. Follow-up ranged from 8 months to 10 years. All the patients use their implants and there were no major nor minor complications. The use of subtotal petrosectomy with cochlear implants is a safe and efficient technique when strict surgical steps and rules are applied. Closure of the external ear canal after previous meatoplasty can be challenging and extreme care dissecting the skin flaps is required. In patients with extensive cholesteatoma, active discharge from the ear with resistant bacteria or an "unstable" situation, the procedure can be staged.

    Full Text Available OBJECTIVE: To study the role of adenoidectomy in the management of otitis media with effusion. TYPE OF STUDY: A prospective clinical study. MATERIALS AND METHODS: 20cases studied in department of ENT, GMCH. The duration of study was from February 2011 to December 2011. Hearing loss assessment in the form of PTA & TYMPANOMETRY before and after adenoidectomy was done. OBSERVATIONS AND RESULTS: Children <14 years were included in the study. Sex wise distribution was observed. Patients categorized according to the symptoms, gender and degree of hearing loss. Satisfactory results observed after adenoidectomy in relation to the improvement in hearing loss. There can be some complications after adenoidectomy but in our studies proper precautions were taken and no complications seen. CONCLUSION: Adenoidectomy is a very effective surgical modality of treatment in patients who are having otitis media with effusion due to adenoid hypertrophy. Conservative management has no role and grommet insertion is not of much value. Adenoidectomy alone has been shown to produce otoscopic clearance of middle ear effusion, alteration of tympanometric status and improvement of hearing loss.

    Full Text Available As sinusites, otites médias agudas e tonsilites são muito freqüentes em crianças. A maioria dessas infecções é causada por vírus, mas em geral, elas são tratadas com antibióticos. O uso inapropriado de antibióticos favorece a seleção, crescimento e disseminação de bactérias resistentes que colonizam as vias respiratórias, atingindo toda a comunidade. A emergência de bactérias resistentes dificulta os tratamentos das infecções respiratórias, sendo essencial desenvolver estratégias efetivas para restringir o uso de antibióticos sem prejudicar as crianças que realmente precisam desses medicamentos. OBJETIVO: Analisar os resultados de estudos randomizados e controlados sobre critérios clínicos e laboratoriais utilizados para diagnóstico e tratamento das tonsilites, sinusites e otites. MÉTODOS: Levantamento dos estudos randomizados e controlados sobre o tema, publicados no MEDLINE e SCIELO, de 2000 a 2006. CONCLUSÕES: Como a maioria dessas infecções evolui bem sem antibióticos, deve-se evitar o uso desses medicamentos a menos que a criança pertença aos grupos de alto risco para complicações ou apresente persistência ou piora dos sintomas com tratamento sintomático. É necessário que os médicos e leigos conheçam melhor a evolução natural das infecções respiratórias agudas e que seja garantido o acesso das crianças a serviços médicos de boa qualidade para orientação e reavaliação, quando necessária.Sinusitis, acute otitis media and tonsillitis are very frequent in children.

  7. Auditory function in the Tc1 mouse model of down syndrome suggests a limited region of human chromosome 21 involved in otitis media.

    Stephanie Kuhn

    Full Text Available Down syndrome is one of the most common congenital disorders leading to a wide range of health problems in humans, including frequent otitis media. The Tc1 mouse carries a significant part of human chromosome 21 (Hsa21 in addition to the full set of mouse chromosomes and shares many phenotypes observed in humans affected by Down syndrome with trisomy of chromosome 21. However, it is unknown whether Tc1 mice exhibit a hearing phenotype and might thus represent a good model for understanding the hearing loss that is common in Down syndrome. In this study we carried out a structural and functional assessment of hearing in Tc1 mice. Auditory brainstem response (ABR measurements in Tc1 mice showed normal thresholds compared to littermate controls and ABR waveform latencies and amplitudes were equivalent to controls. The gross anatomy of the middle and inner ears was also similar between Tc1 and control mice. The physiological properties of cochlear sensory receptors (inner and outer hair cells: IHCs and OHCs were investigated using single-cell patch clamp recordings from the acutely dissected cochleae. Adult Tc1 IHCs exhibited normal resting membrane potentials and expressed all K(+ currents characteristic of control hair cells. However, the size of the large conductance (BK Ca(2+ activated K(+ current (I(K,f, which enables rapid voltage responses essential for accurate sound encoding, was increased in Tc1 IHCs. All physiological properties investigated in OHCs were indistinguishable between the two genotypes. The normal functional hearing and the gross structural anatomy of the middle and inner ears in the Tc1 mouse contrast to that observed in the Ts65Dn model of Down syndrome which shows otitis media. Genes that are trisomic in Ts65Dn but disomic in Tc1 may predispose to otitis media when an additional copy is active.

  8. The Importance of Integration of Stakeholder Views in Core Outcome Set Development: Otitis Media with Effusion in Children with Cleft Palate.

    Nicola L Harman

    Full Text Available 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.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.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, parents and children.

    Full Text Available Aims: Otitis media with effusion (OME is a common cause of hearing and speech impairment in children. The correlation of the clinical, audiological, radiological, and intraoperative findings was carried out so as to make a protocol for early diagnosis and management of OME. It will help prevent the more serious sequelae of OME such as tympanosclerosis, chronic adhesive otitis media, and even chronic suppurative otitis media. Methods: 300 clinically diagnosed patients of OME were studied prospectively. Thereafter, patients underwent impedance audiometry, pure tone audiometry, and X-ray soft tissue nasopharynx for adenoids. The patients were given adequate medical treatment for 3 to 6 months, and the patients who did not respond to the treatment were subjected to adenoidectomy with ear examination under magnification and myringotomy with or without grommet insertion. Results: The mean age at presentation was 5.96 years. Only 32% patients gave a history of hearing loss. About 90% patients had mouth breathing, followed by snoring (84%. About 79% ears had abnormal tympanic membrane appearance and mobility; 65.5% had an abnormality on impedance audiometry; and 69.75% had an air condition threshold level of >20 dB. About 78% patients had either Grade III or Grade IV Adenoid hypertrophy. Adenoidectomy was done in all 300 patients with myringotomy in 472 ears. Grommets were inserted in 365 ears. There was a significant reduction in mean air conduction threshold with an improvement of 8.0 dB and 7.5 dB in right and left ears, respectively at 2 months postoperatively. At 6 th month postoperative, the average improvement from baseline dropped to 6.0 dB in right ear and 5.5 dB in the left ear. Conclusion: OME is the most frequent causes of silent hearing impairment in young children which needs a close vigil. All suspected children (on clinical and otoscopic findings must be subjected to impedance audiometry and X-ray soft tissue nasopharynx for adenoids

    2016-01-01

    Full Text Available Myiasis is a disease caused by fly larvae and aural myiasis is a rare clinic condition often occurring in children or mentally retarded people. We report the case of an unusual presentation of a unilateral aural myiasis in a 3-year-old female child patient belonging to a slum with unilateral chronic otitis media caused by Musca domestica (housefly larvae. Eight larvae were removed from the external auditory canal while five more larvae were located in the middle ear cavity and were removed through perforation of the tympanic membrane. Management of ear myiasis is based on removal of the maggots and cleansing of the ear with ethanol, chloroform, or physiological saline. Physiological saline is preferred in patients who have tympanic membrane perforation. Myiasis is related to personal hygiene. Therefore, to decrease the incidence of these infestations, care, and hygiene standards should be carried out for those at risk through information, education, and communication.

    Objective To explore the diversity of stagnant effusions and the pathologic processes leading to granulation tissue formation in otitis media with effusion(OME). Methods Temporal bone slides from 306 ears with OME were studied histopathologically under the light microscope. Results Results of this study revealed a pathologic process in witch the type and the condition of stagnant effusion in the middle ear cleft was a variable in the dynamics of OME progression from an early stage to an advanced stage. The location of granulation tissue and retentive effusion were found to be closely related. Conclusion Early stage granulation tissue formation exhibited a pathologic process in which granulation tissue formation occurred only in areas where effusion had stagnated or was absorbed. The incidence of the retentive effusion and formation of granulation tissue was much higher and the pathologic changes most extensive in the area around the ossicular chain.

    Principi, Nicola; Marchisio, Paola; Esposito, Susanna

    2016-01-01

    Otitis media with effusion (OME) is a common clinical condition that is associated with hearing loss. It can be diagnosed at least once in approximately 80% of preschool children: 30-40% of them have recurrent episodes, and 5-10% have chronic disease. OME, in recurrent and persistent cases, might significantly delay or impair communication skills, resulting in behavioral and educational difficulties. Several therapeutic approaches have been used to avoid these problems. Most, however, have not been adequately studied, and no definitive conclusions can be drawn. Official guidelines do not recommend the use of decongestants, antihistamines, steroids, or antibiotics. The data are too scanty to assess other interventions, although autoinflation, because it incurs neither cost nor adverse events, deserves attention. Surgical procedures (i.e., tympanostomy tube insertion and adenoidectomy as an adjuvant) can be useful in some cases. This review evaluates all the current OME treatments and preventive measures, including their possible adverse events.

    2011-11-01

    A comprehensive finite element (FE) model of the human ear including the ear canal, middle ear, and spiral cochlea was developed using histological sections of human temporal bone. The cochlea was modeled with three chambers separated by the basilar membrane and Reissner's membrane and filled with perilymphatic fluid. The viscoelastic material behavior was applied to middle ear soft tissues based on dynamic measurements of tissues in our lab. The model was validated using the experimental data obtained in human temporal bones and then used to simulate various stages of otitis media (OM) including the changes of morphology, mechanical properties, pressure, and fluid level in the middle ear. Function alterations of the middle ear and cochlea in OM were derived from the model and compared with the measurements from temporal bones. This study indicates that OM can be simulated in the FE model to predict the hearing loss induced by biomechanical changes of the middle ear and cochlea.

    2011-01-01

    Full Text Available Though the standard canal wall up and canal wall down mastoidectomies provide for reliable disease removal and good functional outcome in most cases with atticoantral chronic suppurative otitis media (CSOM, few cases remain unresponsive to such treatment. This report describes the application of tympanomastoid obliteration with blind sac closure of the EAC as a surgical technique for recurrent CSOM persisting despite multiple previous surgical treatments. Though maximal conductive deafness is an inevitable consequence of this procedure, such morbidity may even otherwise be inevitable in this clinical situation, as scarring and destruction consequent to disease and previous surgical treatments often lead to clinical situations not amenable to tympanoplasty and hearing reconstruction. Further concerns of recurrent epithelial pearls and implantation cholesteatoma can be currently addressed by follow-up MR scanning.

The women were interviewed twice during pregnancy and again 6 months after birth. The outcome "one or more...... associated with a risk of OM. When a Bonferroni correction was introduced, gender, prematurity, parity, maternal age, maternal self-estimated health, taking penicillin during pregnancy, and terminating breastfeeding before age six months, was associated with a risk of early OM. The adjusted ORs of OM...... less than 6 months, had an increased OR of 1.42 (95% CI 1.28-1.58) compared to children being breastfeed beyond 6 months. CONCLUSION: These findings indicate that prenatal factors are of less importance regarding early OM before the age of six months. Postnatal risk factors seem to pose the main risk...

    Watchful waiting (WW) can reduce unnecessary antibiotic use in the treatment of pediatric otitis media (ear infection), but its utility is impaired by underutilization and noncompliance. Guided by advice response theory, the current study proposes advantage and capacity as factors that predict how caregivers evaluate and respond affectively to WW. Parents (N = 373) of at least 1 child age 5 years or younger completed questionnaires that assessed responses to hypothetical WW advice for their youngest child. Perceptions of advantage from WW and the capacity to monitor and manage symptoms predicted advice quality, physician trust, and future compliance both directly and indirectly through negative affect. The findings suggest the elaboration of advice response theory to include more aspects of advice content evaluation (e.g., advantage) and the influence of negative affect. The study also provides practical guidance for physicians seeking to improve caregiver reception of WW advice.

    Mucociliary clearance (MCC), which exists in many systems, is the first defensive mechanism of the human body. Nasal MCC has an important role in transporting the secretions of the nasal cavity and paranasal sinuses along with the trapped inhaled pathogens to the nasopharynx. Physiologic or pathologic situations that effect nasal MCC, such as temperature, humidity, nasal obstruction, allergic rhinitis, chronic infections, etc., lead to impaired MCC and related local or circumjacent system disorders. With this perspective, when a unified airway with a multiple disease principle is considered, investigating the relationship between adenoid hypertrophy (AH), otitis media with effusion (OME) and nasal MCC is logical. In this review, histological and physiologic properties of nasal MCC and its possible role involving pathologic situations such as AH and OME is discussed together with recent literature findings.

    Full Text Available Otitis media with effusion (OME is the commonest cause of hearing loss in children, yet the underlying genetic pathways and mechanisms involved are incompletely understood. Ventilation of the middle ear with tympanostomy tubes is the commonest surgical procedure in children and the best treatment for chronic OME, but the mechanism by which they work remains uncertain. As hypoxia is a common feature of inflamed microenvironments, moderation of hypoxia may be a significant contributory mechanism. We have investigated the occurrence of hypoxia and hypoxia-inducible factor (HIF mediated responses in Junbo and Jeff mouse mutant models, which develop spontaneous chronic otitis media. We found that Jeff and Junbo mice labeled in vivo with pimonidazole showed cellular hypoxia in inflammatory cells in the bulla lumen, and in Junbo the middle ear mucosa was also hypoxic. The bulla fluid inflammatory cell numbers were greater and the upregulation of inflammatory gene networks were more pronounced in Junbo than Jeff. Hif-1α gene expression was elevated in bulla fluid inflammatory cells, and there was upregulation of its target genes including Vegfa in Junbo and Jeff. We therefore investigated the effects in Junbo of small-molecule inhibitors of VEGFR signaling (PTK787, SU-11248, and BAY 43-9006 and destabilizing HIF by inhibiting its chaperone HSP90 with 17-DMAG. We found that both classes of inhibitor significantly reduced hearing loss and the occurrence of bulla fluid and that VEGFR inhibitors moderated angiogenesis and lymphangiogenesis in the inflamed middle ear mucosa. The effectiveness of HSP90 and VEGFR signaling inhibitors in suppressing OM in the Junbo model implicates HIF-mediated VEGF as playing a pivotal role in OM pathogenesis. Our analysis of the Junbo and Jeff mutants highlights the role of hypoxia and HIF-mediated pathways, and we conclude that targeting molecules in HIF-VEGF signaling pathways has therapeutic potential in the treatment of

    Introduction: Vitamin D has been suggested to play a considerable role in the function of the immune system in various infectious, inflammatory, and autoimmune conditions. Otitis media with effusion (OME), defined as the presence of non-purulent fluid within the middle ear without signs or symptoms of suppurative otitis media, has a number of inflammatory predisposing factors. This study was designed to explore the association between vitamin D deficiency and OME. Materials and Methods: In this cross-sectional study, 74 children aged 2–7 years with an obstructive indication for adenotonsillectomy were included. Patients were divided into two groups based on the need for ventilation tube insertion for OME. Thirty-two children were enrolled in the OME group and 42 in the control group. The mean vitamin D level was compared between the two groups. Results: Mean vitamin D concentration in all patients was 11.96±5.85 ng/ml (9.79±4.36 ng/ml in the OME group and 13.61±6.33 ng/ml in the control group; P=0.003). There was also a significant difference in levels of vitamin D in patients referred in winter (9.0±2.94 ng/ml) compared with the summer (19.85±4.21 ng/ml; P=0.001). Data analyzed based on the season in which the patients were referred showed no significant difference between the OME and the control group. Conclusion: Although our results showed lower serum levels of vitamin D in OME patients, the difference was not significant when seasons were taken into consideration. Therefore, the season is an important confounding factor in any research related to vitamin D due to the effect of sun-induced vitamin D.

    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

    Full Text Available This study presents the treatment of 68 children with secretory otitis media. Children underwent adenoid vegetations, nasal speech, conductive hearing loss, ventilation disturbance in Eustachian tube. In all children adenoidectomy was indicated.38 boys and 30 girls at the age of 3-17 were divided in two main groups: * 29 children without hypertrophic (enlarged adenoids, * 39 children with enlarged (hypertrophic adenoids.The surgical treatment included insertion of ventilation tubes and adenoidectomy where there where hypertrophic adenoids.Clinical material was analyzed according to hearing threshold, hearing level, middle ear condition estimated by pure tone audiometry and tympanometry before and after treatment. Data concerning both groups were compared.The results indicated that adenoidectomy combined with the ventilation tubes facilitates secretory otitis media heeling as well as decrease of hearing impairments. That enables prompt restoration of the hearing function as an important precondition for development of the language, social, emotional and academic development of children.

    Full Text Available A 51-year-old woman had been receiving medical treatment for asthma since she was 21 years old. However, her asthma was poorly controlled despite treatment involving combination inhalation of high-dose corticosteroid and long-acting β2-aderenergic agonist (LABA and regularly taking oral steroids. Hearing loss and otorrhea appeared at the age of 44, and she was given a diagnosis of eosinophilic otitis media (EOM and received medical treatment. In 2007, symptoms of asthma and otitis media deteriorated. In December 2009, omalizumab therapy was started for refractory asthma. After 2 months of omalizumab treatment, not only asthma, but also hearing loss improved. It is suggested that early initiation of omalizumab therapy may inhibit the progression of progressive EOM.

    2014-12-01

    Moraxella catarrhalis is a significant cause of otitis media and exacerbations of chronic obstructive pulmonary disease. Here, we characterize a phase-variable DNA methyltransferase (ModM), which contains 5'-CAAC-3' repeats in its open reading frame that mediate high-frequency mutation resulting in reversible on/off switching of ModM expression. Three modM alleles have been identified (modM1-3), with modM2 being the most commonly found allele. Using single-molecule, real-time (SMRT) genome sequencing and methylome analysis, we have determined that the ModM2 methylation target is 5'-GAR(m6)AC-3', and 100% of these sites are methylated in the genome of the M. catarrhalis 25239 ModM2 on strain. Proteomic analysis of ModM2 on and off variants revealed that ModM2 regulates expression of multiple genes that have potential roles in colonization, infection, and protection against host defenses. Investigation of the distribution of modM alleles in a panel of M. catarrhalis strains, isolated from the nasopharynx of healthy children or middle ear effusions from patients with otitis media, revealed a statistically significant association of modM3 with otitis media isolates. The modulation of gene expression via the ModM phase-variable regulon (phasevarion), and the significant association of the modM3 allele with otitis media, suggests a key role for ModM phasevarions in the pathogenesis of this organism.

Of these 3,540 patients, there were a total of 3,331 patients included in the safety analysis, 2,844 in the efficacy analysis, 2,769 in the clinical efficacy analysis, and 461 in the bacteriological efficacy analysis. The incidence of adverse drug reactions (ADRs) was 9.97% (332/3,331 patients), and the major ADRs were gastrointestinal disorders including diarrhoea in 317 patients (9.52%). Diarrhoea was reported in 313 patients (316 events), which were not clinically significant and 94.9% (297/313 patients) were recovery and/or remission. The overall clinical efficacy rate was 94.0% (2,604/2,769 patients). The clinical efficacy rate by the type of infection was 95.6% (415/434 patients) for pneumonia, 93.7% (1,389/1,482 patients) for otitis media and 93.6% (659/704 patients) for sinusitis. The eradication rate of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella (Branhamella) catarrhalis which are major causative organisms in pediatric infection of pneumonia, otitis media and sinusitis were 94.4% (134/142 strains), 92.2% (130/141 strains) and 97.8% (45/46 strains), respectively. The compliance was good in 83.1% of the patients (2,767/3,331 patients). Overall, Orapenem® fine granules 10% for pediatric showed good safety, efficacy, and compliance. These results indicate that Orapenem® fine granules 10% for pediatric is a useful agent in pediatrics with pneumonia or otitis media, or sinusitis.

    The objective of the present study was to evaluate the effectiveness and the safety of balloon dilatation of the cartilaginous portion of the Eustachian tube in the children presenting with relapsing exudative otitis media. A total of 15 children (22 ears) at the age from 3 to 16 years suffering from relapsing exudative otitis media over 18 months in duration were available for the examination. Neither conservative nor surgical treatment produced any stable beneficial effect in these patients. Acoustic impedancometry yielded type B tympanograms. All the children were treated with the use of balloon dilatation of the cartilaginous portion of the Eustachian tube under endotracheal anesthesia. The follow-up examination carried out within 6--8 weeks after the treatment revealed the complete recovery of the function of the middle ear (type A tympanograms) in 11 (73.3%) children. Partial restoration of this function (as evidenced by type C tympanogram) was documented in 4 children. These patients underwent the second course of conservative therapy that resulted in the complete restoration of the function of the middle ear. It is concluded that balloon dilatation of the cartilaginous portion of the Eustachian tube in the children presenting with relapsing exudative otitis media provides the efficient and safe approach to the management of this condition. Being a minimally invasive method, it has good prospects for the practical application and is worth further investigation.

    Summary We present a case of subarachnoid hemorrhage induced by chronic suppurative otitis media, and discuss the possible mechanism here. Chronic suppurnlive otitis media is a common suppurative inflammation of middle ear, which can cause sorts of extracranial and intracranial complications in the situation of lower resistance or higher virulence. However, the condition of subarachnoid heamorrhage casued by chronic suppurative otitis media is quite rare. According to this case and previously published articles, we consider that meningitis may be the main reason of subarachnoid hemorrhage induced by chronic suppurative otitis media.

    To study the extent of surface adenoid biofilm and to evaluate its role in the pathogenesis of chronic otitis media with effusion (COME) in children. The study was carried out on 100 children between 3 and 14 years of age, who were divided into two groups. The first group (50 children) had otitis media with effusion associated with adenoid hypertrophy, whereas the second group (50 children) had adenoid hypertrophy without middle ear effusion. Adenoidectomy with ventilation tube insertion was done for group 1 cases, whereas, only Adenoidectomy was done for group 2 cases. Microbiological study, Scanning electron microscope and multiplex- PCR were done for suspected adenoid biofilms and specimens from middle ear effusion. Adenoids removed from children with COME had higher grade biofilm formation (74 %) than the second group (42 %). No correlation was found between adenoid size and biofilm formation. Culture of adenoid tissue in group 1 patients was positive in 52 % of cases compared to 96 % by PCR, while in group 2 culture of adenoid tissue was positive in 38 % compared to 48 % by PCR. Culture of middle ear fluid was positive in 32 % of cases only compared to 80 % by PCR. A positive correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected and identified by PCR technique. On the other hand, no correlation was found between results of bacterial biofilm visualized by SEM and bacteria detected by culture. The size of the adenoid is not the main determinant factor in OME pathogenesis but the degree of bacterial colonization is much more important. Adenoids in COME may act as a reservoir of chronic infection rather than causing mechanical Eustachian obstruction. Higher grade biofilm formation was found in cases with middle ear effusion than those with adenoid hypertrophy only. These findings support the hypothesis that there would be an association between adenoidal biofilm formation and COME. This study focused on the value of PCR

    To date there is ample evidence suggesting a crucial role for respiratory viruses in the pathogenesis of AOM. Respiratory viral infection appears to initiate the cascade of events that finally leads to development of AOM (Fig. 1). The pathogenesis of AOM is complicated, involving a network of factors, some probably not yet identified, which affect each other in a time-dependent manner. Increased knowledge of the detailed mechanisms of viral infection, the host inflammatory response during URI and the interaction between viruses and bacteria could lead to major advances in the prevention of AOM.

    .On the basis of research evidence, a recommended strategy for improving the care of middle ear infections is to identify the subset of patients least likely to benefit from antibiotic therapy. They include children ages 6 months to 23 months with unilateral disease without severe signs and symptoms (moderate or severe otalgia, otalgia lasting more than 48 hours,or temperature of 39°C [102.2°F]), and those older than 2 years ofage with unilateral or bilateral disease who have mild signs andsymptoms.(9) On the basis of research evidence, the initial treatment of otitis media with effusion is watchful observation. There is little harm in observing a child who is not at risk for speech, language, or learning difficulties compared to medical or surgical intervention.(4) On the basis of research evidence, administration of the annual influenza vaccine and the conjugated pneumococcal vaccination has been shown to have a small but statistically significant impact on the frequency of middle ear disease. (7)(8) On the basis of expert opinion, optimal outcomes depend oncommunication between clinicians and parents. At a minimum , primary care clinicians should state their reasons for their own clinical judgment about appropriate management and for referral to otolaryngology if necessary.

    Full Text Available Conservative medical management of chronic suppurative otitis media (CSOM is an important step in achieving a dry ear which is a prerequisite for the definitive surgical management of non - cholesteotomatous CSOM. Like other chronic diseases, CSOM can limit an individual's employability and quality of life. The microbial profile, antibiotic sensitivity & resistance pattern of CSOM has been changing according to geographical variation and various differences in patient population. A prospective, randomized open study of 110 patients was conduc ted to isolate aerobic & anaerobic organisms and their sensitivity & resistance patterns to various antibiotics among the patients suffering from non - cholesteotomatous CSOM at a charitable tertiary healthcare center located in Navi Mumbai. Pseudomonas aeruginosa was most common aerobic organism isolated (37.7% followed by Staphylococcus aureus ( 31.5 % . Linezolid was found to be most effective drug followed by Amikacin, Streptomycin, and ciprofloxacin. A periodic review of microbiological profile of and antibiotic sensitivity & resistance pattern of the isolates is important for effective management of CSOM

    This study examined the relationship between reading, spelling, and the presence of otitis media (OM) and co-occurring hearing loss (HL) in metropolitan Indigenous Australian children, and compared their reading and spelling outcomes with those of their non-Indigenous peers. OM and HL may hinder language development and phonological awareness skills, but there is little empirical evidence to link OM/HL and literacy in this population. Eighty-six Indigenous and non-Indigenous children attending pre-primary, year one and year two at primary schools in the Perth metropolitan area participated in the study. The ear health of the participants was screened by Telethon Speech and Hearing Centre EarBus in 2011/2012. Participants' reading and spelling skills were tested with culturally modified sub-tests of the Queensland University Inventory of Literacy. Of the 46 Indigenous children, 18 presented with at least one episode of OM and one episode of HL. Results indicated that Indigenous participants had significantly poorer non-word and real word reading and spelling skills than their non-Indigenous peers. There was no significant difference between the groups of Indigenous participants with OM and HL and those with normal ear health on either measure. This research provides evidence to suggest that Indigenous children have ongoing literacy development difficulties and discusses the possibility of OM as one of many impacting factors.

    2004-10-01

    To determine possible selection criteria for ventilation tubes (VTs - grommets), in otitis media with effusion (OME), a randomized trial on 68 children was undertaken. To provide both a baseline predictor and outcome measure in auditory disability, speech-in-noise thresholds were obtained with the IHR-McCormick Automated Toy Test (SiN ATT). Children allocated to surgery (n = 32) and control (n = 36) were followed-up at 3 and 12 months postintervention. Baseline SiN ATT score provided a significant by-treatment interaction in predicting the performance at +3 months, establishing it as an evidence-based indicator. Although average benefits on hearing level score (HL) were also shown, baseline HL was not a valid indicator (no significant interaction). The 40% of the sample with worst baseline SiN experienced high benefit from VTs. In children over 3 years of age, baseline SiN performance can indicate those with OME most likely to benefit from VTs.

    Full Text Available Abstract Background The nontypeable Haemophilus influenzae (NTHi are associated with a spectrum of respiratory mucosal infections including: acute otitis media (AOM; chronic otitis media with effusion (COME; otorrhea; locally invasive diseases such as mastoiditis; as well as a range of systemic disease states, suggesting a wide range of virulence phenotypes. Genomic studies have demonstrated that each clinical strain contains a unique genic distribution from a population-based supragenome, the distributed genome hypothesis. These diverse clinical and genotypic findings suggest that each NTHi strain possesses a unique set of virulence factors that contributes to the course of the disease. Results The local and systemic virulence patterns of ten genomically characterized low-passage clinical NTHi strains (PittAA – PittJJ obtained from children with COME or otorrhea were stratified using the chinchilla model of otitis media (OM. Each isolate was used to bilaterally inoculate six animals and thereafter clinical assessments were carried out daily for 8 days by blinded observers. There was no statistical difference in the time it took for any of the 10 NTHi strains to induce otologic (local disease with respect to any or all of the other strains, however the differences in time to maximal local disease and the severity of local disease were both significant between the strains. Parameters of systemic disease indicated that the strains were not all equivalent: time to development of the systemic disease, maximal systemic scores and mortality were all statistically different among the strains. PittGG induced 100% mortality while PittBB, PittCC, and PittEE produced no mortality. Overall Pitt GG, PittII, and Pitt FF produced the most rapid and most severe local and systemic disease. A post hoc determination of the clinical origins of the 10 NTHi strains revealed that these three strains were of otorrheic origin, whereas the other 7 were from patients

    Full Text Available Background: Chronic Suppurative Otitis Media (CSOM is the major cause of hearing impairment, mainly conductive type of hearing loss. The occurrence of sensorineural hearing loss (SNHL in CSOM is controversial and the controversy is more for safe mucosal type. This study aims to assess the association between SNHL and safe mucosal CSOM and its relation to patient's age, sex, duration of disease, active or inactive disease and speech frequencies. Methods: 100 patients with unilateral mucosal type of CSOM with normal contralateral ear were included in the study. The infected ear was taken as study ear and normal ear as control ear in all patients. All patients underwent hearing assessment by pure tone audiometry for both ears. In case of active disease, ear discharge was first cleared and then audiometric assessment done. Results were statistically compared in all patients for both study and control ears using parameters of patient's age, sex, duration of disease, speech frequency and active or inactive disease. Results: There was significant higher number of study ears with CSOM having average bone conduction threshold of all frequencies above 25 decibels which implies SNHL (21% compared to control contralateral ears without infection (5%. There was higher incidence of SNHL at higher speech frequencies. The incidence also increased with age of patient and duration of disease. The incidence was higher in active stage than inactive or quiescent stage. There was no difference among males and females. Conclusion: Safe mucosal CSOM can cause significant SNHL and risk increases with increasing age, duration of disease, higher speech frequencies and presence of active disease.

    Full Text Available Abstract Background Toll-like receptor (TLR signalling is crucial for innate immune responses to infection. The involvement of TLRs in otitis media (OM, the most prevalent childhood disease in developed countries, has been implicated by studies in middle ear cell lines, by association studies of TLR-related gene polymorphisms, and by altered OM in mice bearing mutations in TLR genes. Activated TLRs signal via two alternative intracellular signaling molecules with differing effects; MyD88 (Myeloid differentiation primary response gene 88 inducing primarily interleukin expression and TRIF (Tir-domain-containing adaptor inducing interferon β mediating type I interferon (IFN expression. We tested the hypothesis that TRIF and type I IFN signaling play a role in OM, using a murine model of OM induced by non-typeable Haemophilus influenzae (NTHi. The ME inflammatory response to NTHi was examined in wild-type (WT and TRIF-/- mice by qPCR, gene microarray, histopathology and bacterial culture. Results Expression of TRIF mRNA was only modesty enhanced during OM, but both type I IFN signalling genes and type I IFN-inducible genes were significantly up-regulated in WT mice. TRIF-deficient mice showed reduced but more persistent mucosal hyperplasia and less leukocyte infiltration into the ME in response to NTHi infection than did WT animals. Viable bacteria could be cultured from MEs of TRIF-/- mice for much longer in the course of disease than was the case for middle ears of WT mice. Conclusion Our results demonstrate that activation of TRIF/type I IFN responses is important in both the pathogenesis and resolution of NTHi-induced OM.

    Full Text Available Purpose: To determine the prevalence of Otitis media (OM and Early childhood caries (ECC and their coexistence in children with a history of faulty feeding patterns. Method: Children aged 5 years and below were recruited at random from dental and medical hospitals. Parents of these children were posed with questions about the feeding methods, feeding patterns such as duration, frequency, position, burping, specific childhood illness etc. Children (120 were examined for ECC by a Paedodontist and OM by an Otolaryngologist and were segregated into three groups i.e. Control group, ECC group and OM group respectively. The ECC group was sub grouped into ECC only and ECC&OM group. The OM group was also similarly sub grouped into OM group and OM&ECC group. Collected data were tabulated and subjected for statistical analysis using Pearson Chi – square test. Results: Prevalence of ECC, OM, and their coexistence increased with age P < 0.001, whereas gender difference was not statistically significant. Overall Prevalence of their coexistence in children was 51.25%. Significant percentages (25% of children in the OM group were fed in supine position. Children fed on demand (47.5% experienced ECC. overall 85% (p=.017 of children had coexistence of ECC&OM fed on demand and during bed time. Significant numbers of children who were burped occasionally after feeding (35% or were not burped at all (12.5% were affected with both ECC and OM. Conclusion: Prevalence of their coexistence was higher in children with OM. Significant association existed between on demand feeding and ECC; supine feeding position and OM. Risk factors in common for both the disease were combined feeding position, on demand, bed time feeding and occasionally burping.

  15. Otitis media in sperm-associated antigen 6 (Spag6-deficient mice.

    Directory of Open Access Journals (Sweden)

    Xiaofei Li

    Full Text Available Mammalian SPAG6 protein is localized to the axoneme central apparatus, and it is required for normal flagella and cilia motility. Recent studies demonstrated that the protein also regulates ciliogenesis and cilia polarity in the epithelial cells of brain ventricles and trachea. Motile cilia are also present in the epithelial cells of the middle ear and Eustachian tubes, where the ciliary system participates in the movement of serous fluid and mucus in the middle ear. Cilia defects are associated with otitis media (OM, presumably due to an inability to efficiently transport fluid, mucus and particles including microorganisms. We investigated the potential role of SPAG6 in the middle ear and Eustachian tubes by studying mice with a targeted mutation in the Spag6 gene. SPAG6 is expressed in the ciliated cells of middle ear epithelial cells. The orientation of the ciliary basal feet was random in the middle ear epithelial cells of Spag6-deficient mice, and there was an associated disrupted localization of the planar cell polarity (PCP protein, FZD6. These features are associated with disordered cilia orientation, confirmed by scanning electron microscopy, which leads to uncoordinated cilia beating. The Spag6 mutant mice were also prone to develop OM. However, there were no significant differences in bacterial populations, epithelial goblet cell density, mucin expression and Eustachian tube angle between the mutant and wild-type mice, suggesting that OM was due to accumulation of fluid and mucus secondary to the ciliary dysfunction. Our studies demonstrate a role for Spag6 in the pathogenesis of OM in mice, possibly through its role in the regulation of cilia/basal body polarity through the PCP-dependent mechanisms in the middle ear and Eustachian tubes.

    Objective To investigate the clinical features, diagnosis and surgical treatment of the secretory otitis media complicated by rhinosinusitis. Methods Ear endoscopy, pure tone audiometry, acoustic impedance and nasal endoscopy, sinus CT were used to examine fullness, hearing loss, more than 3 months in patients with secretory otitis media. 42 cases (65 ears)were diagnosed as secretory otitis media complicated by rhinosinusitis. Surgical and drug treatment were performed on all cases and the effects were analyzed. Results Apart from 1 patient (2 ears) with unknown cause recurrent secretory otitis media, the symptom such as ear fullness, hearing loss of the rest patients were improved. The results of acoustic impedance and pure tone audiometry were basically back to normal. Conclusion Rhinosinusitis were related to secretory otitis media closely. For this reason, we should keep a watchful eye on rhinosinusitis and estimate it when we treat secretory otitis media to prevent misdiagnosis of nose focus complicated by secretory otitis media, resulting in delayed healing of secretory otitis media.%目的 探讨分泌性中耳炎合并鼻-鼻窦炎的临床特征、诊断要点及手术治疗方法.方法 利用耳内镜、纯音测听、声阻抗及鼻内镜、鼻窦CT,对耳闷、听力下降3个月以上的分泌性中耳炎患者进行检查,确诊为分泌性中耳炎合并鼻-鼻窦炎42例(65耳),并对所有患者进行了手术及药物治疗,分析其疗效.结果 除1例(2耳)患者不明原因反复发作分泌性中耳炎外,其余所有患者耳闷、听力下降等症状均有改善,声阻抗、纯音听力测试结果基本恢复正常.结论 鼻-鼻窦炎与分泌性中耳炎发病有密切相关性,因此治疗分泌性中耳炎时应关注、评估鼻-鼻窦炎,以防漏诊与分泌性中耳炎共同存在的鼻部病灶,导致分泌性中耳炎迁延不愈.

    Objective To discuss the clinical features of otitis media in Uighur and Han neonate. Methods Eighty-four cases of neonatal otitis media patients admitted January 2012 to January 2015 in neonatal department of Xinjiang autonomous regions maternal and child health-care hospital were selected, they were divided into two groups (36 Uighur, 48Han) according to the ethnic, and the features of acute otitis media in neonates were analyzed. Results In 36 cases of Uighur infantile otitis media, external purulent secretion was seen in 9 cases (25%), only 12 cases (33.3%) caused fever, 9 cases (25%) were observed because of irritable and crying, other non-specific manifestations of 6 cases (jaundice,16.6%). In 48 cases of Han infantile otitis media, external purulent secretion accompanied with jaundice was seen in 15 cases (31.2%), only 9 cases (18.7%) caused fever, 6 cases (12.5) caused ear scratching and head shaking because of earache, other non-specific manifestations of 18 cases(jaundice,37.5%). Conclusion Clinical features of otitis media in both Uighur and Han neonates are variable and atypical. But the constituent ratios of complication of otitis media between Uighur and Han infantile patients have difference. Pneumonia and septicemia of newborn are frequently observed in Uighur neonatal otitis media, and the acute upper respiratory tract infection is often diagnosed in Han neonatal otitis media. Pediatricians should improve the understanding on otitis media, for the atypical clinical symptoms, early diagnosis and early treatment necessary to both Uighur and Han neonatal otitis media.%目的:探讨新疆维吾尔自治区妇幼保健院新生儿科维吾尔族(简称维族)、汉族新生儿中耳炎的病因及临床特点,为临床医师早期认识和诊治提供依据。方法抽取我院新生儿科2012年1月-2015年1月份收治的84例患中耳炎的维、汉族新生儿作为研究对象,其中维族36例(男15例,女21例),汉族48

    The practicability, safety and clinical efficacy of intracavitary therapy with Re-186-colloid in patients with recurrent otitis media and paranasal sinusitis, resistant to pharmacotherapy and surgical treatment is demonstrated based on a preliminary treatment trial. Methods: the authors report on a total of 39 applications of 5-35 MBq {sup 186}Re-colloid into the tympanon and the paranasal sinuses in six patients. Biodistribution and biokinetics were studied by gamma camera imaging. Clinical success was documented 6-20 months after therapy both by patients self-evaluation and by objective rhinootological follow-up, using a four-step score from -1 to+2. Results: no serious side effects were seen. There was good to excellent clinical improvement with a mean score of +1.44 {+-} 0.5 by patients self-evaluation and by physicians scoring of +0.81 {+-} 0.9 with only negligible extracranial tracer deposition. Conclusion: this novel treatment option using intracavitary application of Re-186-colloid in chronic otitis media and sinusitis is safe and effective. The term Radio-Tympano-Sinu-Orthesis (RTSO) might be proposed analogously to the well-known radiosynoviorthesis (RSO). (orig.)

    Malassezia pachydermatis is a yeast that is frequently involved as a secondary/perpetuating factor in canine otitis externa. Topical therapies with different antifungal agents, mainly azole compounds, are generally successful in controlling the yeast overgrowth, but treatment failure and rapid recurrences are common. This study compared the in vitro antifungal susceptibility of M. pachydermatis isolates obtained from chronic and acute cases of otitis externa. The aim was to assess the possible onset of resistance mechanisms in isolates involved in long-lasting episodes with poor response to treatment. We evaluated the in vitro susceptibility to miconazole (MCZ) and clotrimazole (CTZ) of 42 isolates of M. pachydermatis obtained from dogs with chronic (group A, n = 25) and acute otitis (group B, n = 17), using a modified CLSI M27-A3 microdilution method. All isolates were inhibited by the antifungal agents employed, but Malassezia isolates from group A were significantly associated with higher minimum inhibitory concentration (MIC) values for both agents (Median MIC values: MCZ group A 2 µg/ml, group B 1 µg/ml; CTZ group A 8 µg/ml, group B 4 µg/ml). These findings prove that these isolates had a reduced in vitro susceptibility to the antifungal agents tested. However, it is unlikely that this could have any influence on the outcome of a topical treatment. Indeed, marketed products include concentrations of the tested agents that largely exceed even the highest MICs found in this study (in most cases at least 1,000 × the MIC, or greater). In conclusion, this study suggests that isolates of M. pachydermatis involved in chronic cases of canine external otitis and exposed to repeated antifungal treatments are unlikely to develop mechanisms of resistance of clinical relevance.

    To ascertain the usefulness of Mongolian gerbils as an inbred model for otitis media, 52 Mongolian gerbils (Meriones unguiculatus, strain MONT/Tum) were compared with 26 chinchillas (Chinchilla laniger) for susceptibility to Streptococcus pneumoniae type 3. Haemophilus influenzae type b, and a polymicrobic culture including anaerobes (Streptococcus intermedius, Propionibacterium acnes, Staphylococcus epidermidis, and Corynebacterium sp.). Organisms were inoculated percutaneously into the superior chamber of the middle ear bulla. The gerbils and chinchillas shared similar susceptibilities and responses to the inoculated organisms as determined by X-ray, otoscopic, histopathological, and microbiological determinations at 5 to 7 days. Koch's postulate studies proved the role of S. pneumoniae and H. influenzae in the pathology found in both animal models. The animals were also susceptible to the polymicrobic culture, although the relative virulence of the individual members of this mixture was low, suggesting that these species potentiated as a polymicrobic mixture. The Corynebacterium sp. appeared to elicit the greatest histopathological response in chronic (8-week) studies in gerbils. The gerbils were found to be useful as an alternative animal model for the study of otitis media of bacterial etiology.

    The objective of this study was to evaluate the role of group 3 innate lymphoid cells (ILC3) in the middle ear (ME) mucosal response to bacterial infection in a rat model. To confirm the role of ILC3 in bacterially induced otitis media (OM), the serum concentrations of IL-17 and IL-22 were determined by ELISA, and the tissue expression of IL-17 and IL-22 in infected ME mucosa was assessed by immunohistochemical staining. Immunohistochemical staining of specific cell surface markers was also assessed to confirm the origin of the cells expressing IL-17 and IL-22. Twenty Sprague-Dawley rats were used in the surgically-induced animal model of OM. OM was induced by inoculation of non-typeable Haemophilus influenzae into the ME cavity of the rats. The rats were divided into four experimental groups: three infected groups and one control group. Infected groups were subdivided into sets of 5 rats, one for each of the three time points (1, 4 and 7 days post-inoculation). For determination of rat IL-17 and IL-22 levels in infected rats and control rats, infected or control ME mucosa sections were analyzed by immunohistochemistry with specific antibodies directed against IL-17 and IL-22. Immunohistochemical staining for CD3, RORγt, and NKp46 were also conducted on the samples to confirm the origin of cells expressing IL-17 and IL-22. IL-17 and IL-22 serum concentrations were significantly increased in the infected rats compared to control rats. Immunohistochemical staining revealed increased IL-17 and IL-22 expressions in all infected ME mucosae from the first day after inoculation. In addition, the results of tissue staining for the specific surface markers were negative for CD3 and NKp46, but were highly positive for RORγt. IL-17 and IL-22 revealed their association with the bacterially induced proliferative and hyperplastic responses of ME mucosa, which are characteristic features in pathogenesis of OM. Surface marker examination showed that the source cells for IL-17

    Full Text Available BACKGROUND: Middle ear infection is one of the most common condition in ENT practice, particularly in our country. Its significance lies in its chronicity and its dreaded complications like hearing loss and cholesteatoma. Chronic suppurative Otitis media and its complications are among the most common conditions seen by both the otologist and pediatrician. Both gram positive and negative organisms are responsible for infection of the middle ear. AIMS: The study was primarily carried out in 200 cases of C.S.O.M. to determine the bacteriological flora and to study the antibiotic sensitivity pattern of the organisms isolated on culture from discharging ears. RESULTS: In our study Pseudomonas aeruginosa was found to be the most common isolated bacteria (40.65% [100/246], followed by Staphylococcus aureus (14.63%[36/246], Klebsiella aerogenes (11.78%[29/246] and Proteus Mirabilis (10.56%[26/246]. Among the anerobic organisms Peptostreptococcus (5.69% was the most common followed by Propionibacterium (4.06% and Bacteroids spp. (3.65%. Amikacin was the most effective antibiotic in the present study. It was effective against maximum number of strains 97(95.48% followed by Gentamycin 95(92.36% and Ciprofloxacin 93(91.30%. Cefoperazone 88(86.42%, Cefotaxime 78(74.54% and Ofloxacin 64(62.68%. CONCLUSION: Efficient and effective treatment of CSOM is based on the knowledge of causative micro-organisms and thus their antimicrobial sensitivity ensures proper clinical recovery and avoidance of the possible dreaded complications. It has been observed that human negligence is one of the main factor responsible for the development of antibiotic resistance. Along with the indiscriminate use of antibiotics by the treating physician the lack of compliance on part of the patient also results in emergence of resistance and thus in treatment failure. It has been frequently encountered that as soon as the symptoms subside and improvement in condition occurs, many

    Full Text Available OBJECTIVES: In recent years welfare in Denmark has increased which might be expected to reduce otitis media (OM incidence. We examined the age-specific incidence of OM in a nation-wide cohort of children aged 0-7 years born in 1996-2003 (Danish National Birth Cohort, DNBC. Only selection was ability to understand and speak Danish. METHODS: Information of OM and ventilation tubes (VT was collected through three maternal interviews at 6-month, 18-month and 7-years of age and based on this age-specific and cumulative incidence of OM was calculated. As different numbers of the total population answered the different interviews, the calculations are done with different denominators. The information in DNBC was validated against two population based registries containing information of VT insertions. RESULTS: Cumulative incidence of OM at 7 years was 60.6% (31,982/52,755. For children with OM, 16.2% (7143/44194 had their first OM episodes between 0-6 months of age, 44.3% (19579/44194 between 7-18 months, and 39.5% (17472/44194 between 19 months and 7 years. Four or more OM episodes before 7 years were reported by 39.5% (12620/31982 and by 64.0% (2482/3881 of those who had their OM debut between 0-6 months; by 48.2% (4998/10378 with debut between 7-18 months; and by 28.7% (4996/17344 with debut between 19 months and 7 years. These figures are essentially unchanged from earlier figures from Denmark. VT insertion at least once was reported by 26,1% in the 7-year interview. Assuming recordings in the Danish National Patient Registry to be gold standard, maternal self-reportings in DNBC of insertion of VT showed high sensitivity (96.4%, specificity (98.2%, and positive (94.8% and negative predictive values (98.8%. CONCLUSION: OM affects nearly 2/3 of preschool children in Denmark despite reduction in known OM risk factors.

    The hypertrophic adenoid may promote chronic suppurative otitis media in children as it fulfills its immune function. The number of lymphocytes in the adenoid and their cooperation in the immune response depend of on their proliferation and migration to the effector sites. Interleukin 7 (IL-7) is essential for the normal development and function lymphocytes. IL-7 plays pivotal role for activation and proliferation of T and B cells. The heterodimeric interleukin-7 receptor (IL-7R) is composed of the IL-7Rα (127) and the common cytokine receptor γc (CD132). The aim of this study was to evaluate the percentage of lymphocytes T (CD4(+) and CD8(+)) with IL-7R (CD127 and CD132) expression in hypertrophic adenoid in children suffering with otitis media with effusion for a duration of 3 months. Adenoid excised due to hypertrophy with or without chronic otitis media with effusion was used as study material. CD4(+) CD127(+), CD4(+)132(+), CD8(+)CD127(+) and CD8(+)CD132(+) cell subpopulations were identified using monoclonal antibodies and flow cytometry. The percentage of CD4(+) and CD8(+) T cells with CD127 receptor expression in hypertrophic adenoid of children with otitis media with effusion was statistically significantly higher than in hypertrophic adenoid group. The percentage of CD4(+) T cells with CD132 expression in the study group was statistically significantly higher than in the reference group. The percentage of CD8(+) T cells with CD132(+) expression was not statistically different in both groups. The increased percentage of T lymphocytes with IL-7R expression (CD127 and CD132) in hypertrophic adenoid seems to influence the quantity of lymphocytes and upset the immunological function of tonsils which can influence the course of otitis media with effusion.

    Full Text Available A Otite Média é uma das doenças infecciosas mais comuns da infância e a diminuição de sua incidência levaria a um grande impacto econômico e social para o mundo. Como uma das formas de prevenção temos as vacinas. As duas vacinas escolhidas para esta revisão são as vacinas antipneumocócica e antiinfluenza. Esta revisão da literatura procurou mostrar os resultados dos principais estudos sobre essas vacinas e seu papel na prevenção da otite média. A vacina antipneumocócica polissacarídea 23-valente não alterou a incidência de otite média pela ineficácia para menores de 2 anos, grupo de maior incidência dessa enfermidade. A vacina antipneumocócica heptavalente, apesar de não provocar grande queda na incidência geral de otite média, mudou o perfil de seus microorganismos causadores, diminuindo os episódios de otite média com efusão e recorrente e aumentando as otites causadas por H. influenza, M. catarrhalis e sorotipos de pneumococo ausentes da vacina heptavalente. A vacina antiinfluenza com vírus inativado mostrou-se efetiva na redução da otite média aguda nos períodos de maior incidência desse vírus. Os otorrinolaringologistas devem estar cientes do papel dessas novas vacinas já disponíveis no Brasil e seu impacto na redução da otite média, para saber orientar adequadamente os seus pacientes.Otitis media is one of the most common infectious diseases of infancy; a reduction in its incidence would have a significant economic and social impact.

    Objective To investigate the effect of exogenous surfactant on Eustachian tube opening function. Methods This reasarch measures for the Eustachian tube opening pressure by injection of surface active substance into middle ear space, studying the effect of surfactant on Eustachian tube opening function. Results It has been showed that the injection of killed streptococcus pneumoneac bacteria by the transtympanic route, successfully developed a secretory otitis media model. Eustachian tube opening pressure in ears with SOM was significantly greater than those without effusion (P<0.01). Irrigation the middle ear space with surfactant resulted in a dramatic decrease in eustachian tube passive opening pressure in both normal and patients (P<0.01). Conclusion The results indicate that flushing with exogenous surfactant by the transtympanic rote reduce of eustachian tube surface tension, and it benefits the Eustachian tube opening.

    Several human-adapted bacterial pathogens use a phasevarion (ie, a phase-variable regulon) to rapidly and reversibly regulate the expression of many genes, which include known virulence factors, yet the influence of phasevarion-mediated regulation in pathogenesis remains poorly understood. Here we examine the impact of the nontypeable Haemophilus influenzae (NTHI) ModA2 phasevarion on pathogenesis and disease severity in a chinchilla model of experimental otitis media. Chinchillas were challenged with NTHI variant populations that were either inoculated ON and remained ON, inoculated OFF and shifted ON, or inoculated OFF and remained OFF, within the middle ear. We show that populations that shift from OFF to ON within the middle ear induce significantly greater disease severity than populations that are unable to shift. These observations support the importance of phasevarion switching in NTHI pathogenesis and the necessity to considered phasevarion regulation when developing methods to treat and prevent infection.

    Properdin is an initiator and stabilizer of the alternative complement activation pathway (AP). Deficiency of properdin is a rare X-linked condition characterized by increased susceptibility to infection with Neisseria meningitidis associated with a high mortality rate. We report properdin deficiency in a large Pakistani family. The index cases were found by screening for immunodeficiency due to a history of recurrent infections. This revealed absent AP activity, but normal classical and lectin pathway activity. Sequencing of the properdin gene (PFC) revealed a novel frameshift mutation. When all available relatives (n=24) were screened for the mutation, four affected males, four female carriers and a male heterozygous carrier were identified. He was subsequently diagnosed with Klinefelter syndrome. A questionnaire revealed a striking association between properdin deficiency and recurrent otitis media (P=0.0012), as well as recurrent pneumonia (P=0.0017). This study is the first to show a significant association between properdin deficiency and recurrent infections.

    Full Text Available Introduction & Objective: The diagnostic value of endoscopic and microscopic procedures for viewing different structures of middle ear has been widely assessed however, no published study is available for comparing the diagnostic value of them in chronic otitis media patients. The present study conducted to compare diagnostic value of these two procedures for as-sessment of middle ear normal structures and possible defects in these patients. Materials & Methods: In a prospective descriptive analytical study, fifty eight consecutive pa-tients older than 15 years who suffered from chronic otitis media and were candidates for tympanoplasty with or without mastoidectomy were included into the study and underwent operation. After entering the middle ear by post auricular incision and elevation of a tym-panomeatal flap, and prior to surgery , the middle ear was first examined by an operating mi-croscope in different bed and microscope positions and by performing gentle maneuvers on the head and then was reevaluated using a rigid 0 & 30 degree sinoscope. The visible areas of middle ear were separately noted. Results: Structures of epitympanum, posterior mesotympanum, and hypotympanum structures were more visible using endoscope compared with microscope(P0.05. Conclusion: Endoscopic and microscopic procedures had similar diagnostic values to view ossicular chain mobility and reflexes of round window as well as to detect ossicular chain erosions, but different anatomical parts and more hidden pits of the middle ear such as epitympanum, posterior mesotympanum, and hypotympanum are more visible by an endoscopic tool.In case of pathologic conditions, endoscopic approach is recommended for better observation and adequate evaluation of the location before and after the removal of the lesion.

    Full Text Available Abstract Background Chronic suppurative otitis media (CSOM is frequently associated with symptoms of inflammation like discharge from the ear or pain. In many cases, patients suffer from hearing loss causing communication problems and social withdrawal. The objective of this work was to collect prospective audiological data and data on general and disease-specific quality of life with validated quality of life measurement instruments to assess the impact of the disease on health-related quality of life (HR-QOL. Methods 121 patients were included in the study. Patients were clinically examined in the hospital before and 6 months after surgery including audiological testing. They filled in the quality of life questionnaires SF-36 and Chronic Otitis Media Outcome Test 15 (COMOT-15 pre-operatively and 6 and 12 months post-operatively, respectively. Results Complete data records from 90 patients were available for statistical analysis. Disease-specific HR-QOL in patients with CSOM improved after tympanoplasty in all the scales of the COMOT-15. There was no difference in HR-QOL assessment between patients with mesotympanic respectively epitympanic CSOM. However, we did find the outcome to be worse in patients who received revision surgery compared with those receiving primary surgery. Audiometric findings correlated very well with the subscale hearing function from the COMOT-15 questionnaire. General HR-QOL measured with the SF-36 was not significantly changed by tympanoplasty. Conclusions Tympanoplasty did lead to a significant improvement of disease-specific HR-QOL in patients with CSOM while general HR-QOL did not change. Very well correlations were found between the subscale hearing function from the COMOT-15 questionnaire and audiological findings. Revision surgery seems to be a predictor for a worse outcome.

    Full Text Available Background: Otitis media with effusion is one of the leading causes of hearing loss in children. Effective treatment of effusion in the middle ear requires appropriate empirical treatment and characterization of responsible pathogens. Objective of the present study was to detect pathogens in clinical samples from patients with otitis media with effusion in our area and to determine the sensitivity profile of isolated organisms to commonly used antibiotics. Methods: Sixty three samples of middle ear effusion were aseptically obtained from 36 children, who had been treated up to at least two weeks before sampling. They were analyzed using standard bacteriological and multiplex polymerase chain reaction (PCR assays. Antibiotic susceptibility tests were also performed. Results: PCR analysis showed that DNA of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were present in 60 (95.2% of the samples. The culture-positive effusion for Streptococcus Pneumoniae, HaemophilusInfluenzae and Moraxella catarrhalis was 34.9%. Almost all isolates of Streptococcus pneumoniaee were sensitive to ciprofloxacin and erythromycin, and none of them was sensitive to co-trimoxazole. None of H. Influenzae isolates was sensitive to erythromycin, cefixim, co-trimoxazole, ampicillin and amoxicillin. None of M. Catarrhalis isolates was sensitive to ceftriaxone, co-trimoxazole, ampicillin and amoxicillin. Conclusion: Compared with other studies using PCR method, the number of H. influenza isolates was in higher in the present study (95.2%. Antibiotic sensitivity profiles of pathogens isolated in this study were different from others. Thus, we can determine empirical antibiotic therapy based on sensi-tivity profile in our geographic area.

    Full Text Available Background: Staphylococcal superantigens (SAg's may have some role in otitis media with effusion (OME. The aim of this study was the search of staphylococcal SAg's in middle ear effusion of children with OME.  Methods: This cross sectional-analytic study was done in ENT & pediatric wards upon 64 children with otitis media with effusion (OME between 1-15 years, (mean age=7.42+4 years of Rasoul Akram University Hospital, Tehran, Iran in 2009-2011. Fifty six percent (36 of cases were male, 43.8% (28 were female. Staphylococcal SAg's; Toxic Shock Syndrome Toxin-1 (TSST-1, Staphylococcal enterotoxin A, B, C, D (Enzyme immune assay, AB Cam, USA were detected in middle ear effusion samples after conventional culture.Results: None type of SAg's found in 39% of OME cases, enterotoxin B found in: 22%; enterotoxin A: 17%, enterotoxin C: 15.6%, enterotoxin D: 12.5%, Toxic Shock Syndrome Toxin-1 (TSST-1: 7.8% Mean age of cases with positive TSST-1, enterotoxin A, B, C, and D was: 1, 5, 8.6, 9.6 and 9.6 years respectively. Positive TSST had no agreement with positive enterotoxin A and C but had weak agreement with type B and D. Mean age of cases with positive TSST was one years which had significant difference with (7.9 years in cases with negative TSST test (P<0.0001.Conclusion: At least one or more type of staphylococcal toxins had found in middle ear effusion of 70% of OME cases with negative culture for Staphylococcus aureus. Even in culture negative cases, staphylococcal toxins might have some immunologic role in middle ear effusion forming. Finding the SAg's (at least one type are important for treatment of immunosuppressive or corticosteroid in cases with resistant OME.

    As longer lives have become possible due to advances in medical technology and diagnostic technology in recent years, weakly toxic fungus have been emerging as causative agents of opportunistic infections, primarily in high-risk groups. We report a case in which the yeast-like fungus Stephanoascus ciferii, which has morphological characteristics that differ from those of the more common Candida species, was isolated by culturing the aural discharge of a patient with intractable otitis media. Drug susceptibility testing showed that it was resistant to fluconazole, flucytosine, and itraconazole, suggesting that it is a species that has a strong tendency to become resistant. The principal sites of infection by Stephanoascus ciferii are thought to be in the ENT area, but in other countries it has been isolated from patients with acute myeloid leukemia and immunodeficiency as well as superficial mycoses, and it may also be a causative agent of deep mycoses. We therefore think that it is necessary to bear in mind detection in other areas outside the ENT field and to adequately monitor the circumstances under which this fungus is isolated.

    Involvement of the middle ear after viral infections of the upper airways may lead to serous otitis media with effusion in the absence of bacterial infection. This can be accompanied by a concomitant shading of the mastoid air cells, which could manifest as a reduced opacity on computed tomography (CT) in the absence of a history of chronic mastoiditis or acute inflammatory signs. This can lead to a subsequent impairment of inner ear function. CT scans reveal an extended pneumatization of the temporal bones in affected patients. Inner ear hearing impairment can probably be attributed to a concomitant labyrinthine reaction-the so-called toxic inner ear lesion. If no remission occurs within 5 days after initial conservative treatment (paracentesis or hemorrheologic infusions), surgical treatment with a mastoidectomy can accelerate hearing restoration. We conducted a retrospective, nonrandomized study of short- and long-term hearing outcomes in patients with a toxic inner ear lesion who had been treated with conservative measures alone (CONS group) or with surgery (SURG group) in a tertiary care referral center. Our study group was made up of 52 consecutively presenting patients (57 ears) who had been seen over a 10-year period; there were 20 patients (21 ears) in the CONS group and 32 patients (36 ears) in the SURG group. Initially, 15 CONS patients (75%) and 18 SURG patients (56%) complained of dizziness or a balance disorder. The initial averaged sensorineural hearing loss (over 0.5, 1.0, 2.0, and 3.0 kHz) was 32.4 ± 15.6 dB in the CONS group and 35.4 ± 12.0 dB in the SURG group. At follow-up (mean: 31.7 mo), the SURG group experienced a significantly greater improvement in hearing (p = 0.025). We conclude that patients with viral otitis media and concomitant noninflammatory mastoiditis with impairment of inner ear function (sensorineural hearing loss) experience a better hearing outcome when a mastoidectomy is performed during primary treatment.

    Full Text Available Objectives. Detection of extraesophageal reflux (EER in children with chronic otitis media with effusion (OME using three different diagnostic methods. Methods. Children between 1 and 7 years with OME who underwent adenoidectomy and myringotomy with insertion of a ventilation tube were included in this prospective study. EER was detected using three methods: oropharyngeal pH was monitored for 24 hours using the Restech system; detection of pepsin in middle ear fluid obtained during myringotomy was done using Peptest, and detection of pepsin in an adenoid specimen was done immunohistochemically. Results. Altogether 21 children were included in the study. Pathological oropharyngeal pH was confirmed in 13/21 (61.9% children. Pepsin in the middle ear fluid was present in 5/21 (23.8% children; these 5 patients were diagnosed with the most severe EER established through monitoring of oropharyngeal pH. No specimen of adenoids tested was positive for pepsin upon immunohistochemical examination. Conclusions. Diagnosis of EER in patients with OME using Restech is sensitive but less specific when compared to the detection of pepsin in middle ear fluid using Peptest. Pepsin in the middle ear was consistently present in patients with RYAN score above 200, and these patients in particular could potentially profit from antireflux therapy.
