RESUMEN
OBJECTIVE: Balloon Eustachian tuboplasty (BET) appears to be a promising therapeutic option for Eustachian tube dysfunction. However, data are lacking on its effect in adults with chronic otitis media with effusion (COME) and whether it should be combined with tympanocentesis. The aim of our study was to determine if there is a beneficial effect of BET combined with tympanocentesis compared with BET only and provide data on the effect of BET in adults with COME. STUDY DESIGN: Randomized clinical trial. SETTING: Tertiary referral hospital. PARTICIPANTS: Adults with COME lasting more than 6 months after tympanostomy tube exclusion. Among 40 eligible ears, 30 were randomized to treatment. INTERVENTION: BET (group 1) versus BET with concurrent tympanocentesis (group 2). MAIN OUTCOME MEASURES: Tympanometry, Valsalva or Toynbee maneuver with tympanometry verification, Eustachian Tube Dysfunction Questionnaire, and pure-tone audiometry. RESULTS: A total of 25 patients (14 ears in group 1 and 15 ears in group 2) were included in the analysis. No significant difference in the effect of treatment was found between the groups. When patients were evaluated as one group, after 2, 6, and 12 months, improvement was found in tympanometry in 55, 48, and 48%; in the ability to perform maneuvers in 55, 41, and 41%; in audiometry in 69, 62, and 59%; and in questionnaire scores in 76, 72, and 69%, respectively. CONCLUSIONS: There was no beneficial outcome of tympanocentesis performed concurrently with BET and therefore it should not be routinely recommended. The success of therapy appears to be reduced compared with other pathologies caused by Eustachian tube dysfunction.

PURPOSE: Some studies have demonstrated that vascular endothelial growth factor (VEGF) plays a critical role in the pathogenesis of otitis media with effusion (OME) in animal models. However, the levels of VEGF and its receptors in adult OME have not been clarified. Our study was designed to detect the levels of VEGF and its receptors in adult OME and explore their relationship with effusion types, duration and prognosis of OME. METHODS: 61 patients with secretory otitis media were enrolled including 21 males and 40 females, with an average age of 54.7 ± 17.5 years. The middle-ear effusions were collected by tympanocentesis or myringotomy. The protein concentrations were determined by enzyme-linked immunosorbent assay and messenger RNA by real-time quantitative PCR. RESULTS: VEGF level was higher in AOME group, but not correlated with the recurrence of OME. VEGFR1 and VEGFR2 levels were lower in recurrent group compared with non-recurrent group. VEGFR2 level was higher in serous effusions than mucoid effusions. VEGF messenger RNA was positively correlated both with HIF-1α and MUC5B. CONCLUSIONS: VEGF and its receptors function to induce the production of middle-ear effusions (MEEs) at acute stage of OME rather than chronic or recurrent stage, which is mainly mediated by HIF-1α pathway. The formation of mucoid effusions is associated with MUC5B and VEGFR2, but not with duration and recurrence of OME.

OBJECTIVES: To evaluate the epidemiology, microbiology, Streptococcus pneumoniae serotypes distribution and serious bacterial infections (SBIs) occurrence in infants <2 months of age with tympanocentesis-documented acute otitis media (AOM), before and after the introduction of pneumococcal conjugate vaccines (PCVs). METHODS: The medical records of all hospitalized infants with AOM who underwent tympanocentesis during 2005-2014 were reviewed. RESULTS: Of the 303 infants with AOM who were diagnosed by an ENT specialist, 182 underwent tympanocentesis, 92 during 2005-2009 (prevaccine period) and 90 during 2010-2014 (postvaccine period). Streptococcus pneumoniae and nontypeable Hemophilus influenzae were isolated in 46/92 (50%) and 37/92 (40.2%) patients during 2005-2009 and decreased to 27/90 (30%) and 21/90 (23.3%). Respectively, during 2010-2014 (Pâ¯=â¯0.006 and Pâ¯=â¯0.001). The proportion of culture-negative patients increased from 18/92 (19.6%) during 2005-2009 to 32/90 (35.6%) during 2010-2014 (Pâ¯=â¯0.02). There were only 6 (3.3%) patients <2 weeks of age. The most common S. pneumoniae vaccine serotypes isolated during 2005-2009 were 5, 3, 1, 19F and 14 (15.2%, 13.0%, 10.9%, 6.5%, and 4.3%, respectively) and 3, 5, 1, 14 and 19A (22.2%, 11.1%, 7.4%, 7.4%, and 7.4%, respectively) during 2010-2014. The proportion of culture-positive patients decreased during 2013-2014 compared with 2011-2012 (7/18, 38.9% vs. 40/54, 74.1%, Pâ¯=â¯0.007). Serotypes 1 and 5 were not isolated during 2013-2014 and serotype 19A was not isolated during 2011-2014. . SBIs were recorded in 23/182 (12.64%) patients and urinary tract infections represented 19/23 (82.61%) of them (Escherichia coli isolated in 12, 63.2%). CONCLUSIONS: The overall number of AOM cases needing tympanocentesis seen at the PER and the proportion of S. pneumoniae and nontypeable H. influenzae-AOM decreased while the proportion of culture-negative AOM increased following the introduction of PCVs. SBIs associated with AOM were frequent and were represented mostly by urinary tract infections caused by pathogens unrelated to the etiologic agents of AOM.

BACKGROUND: Complex otitis media (OM) may present with intact tympanic membrane or spontaneous otorrhea. We compared dynamics of intact tympanic membrane and spontaneous otorrhea OM following 7- and 13-valent conjugated vaccines (PCV7, PCV13) implementation, since differences in dynamics may imply different underlying mechanisms. METHODS: A prospective, population-based, active surveillance. Episodes with middle-ear fluid cultures in childrenâ¯<â¯3â¯years were included. Defined sub-periods were: pre-pneumococcal conjugated vaccines (PCV) (2004-2008); PCV7 (2009-2011); PCV13 (2014-2016). RESULTS: Of 7705 episodes, 57.2% had intact tympanic membrane, 16.8% spontaneous otorrhea, 26.0% unknown. In the pre-PCV period, the spontaneous otorrhea group was older and had higher proportions of factors associated with recurrence/chronicity. During the PCV7 period, spontaneous otorrhea and intact tympanic membrane episodes caused by PCV13 serotypes decreased significantly (43% and 51%, respectively) and those caused by non-PCV13 serotypes and culture-negative episodes increased significantly. However, rates increases were steeper in the spontaneous otorrhea group for both non-PCV13 serotypes (117% vs. 38%) and culture-negative (720% vs. 69%). In the spontaneous otorrhea group, nontypeable Haemophilus influenzae rates increased non-significantly by 10% and all-cause OM rates increased significantly by 56%, while in the intact tympanic membrane group the respective rates decreased significantly by 22% and 11%. These trends were especially pronounced in ages 24-35â¯months. Despite these differences, after PCV13 introduction, both spontaneous otorrhea and intact tympanic membrane rates declined for all outcomes. CONCLUSIONS: Spontaneous otorrhea was associated with older age, frequent history of complex OM and delayed PCV impact, suggesting a higher proportion of advanced-stage complex OM.

PURPOSE: Adult chronic otitis media with effusion (COME) is characterized by Eustachian tube dysfunction and mucosal inflammation, which management has long been a challenge because of high recurrence. This study was to investigate the pathological changes of Eustachian tube mucosa and optimized treatment. MATERIALS AND METHODS: Retrospective study of four groups: I: tympanic paracentesis, II: balloon Eustachian tuboplasty (BET), III: BET plus tympanic paracentesis, IV: BET and tympanic paracentesis with methylprednisolone irrigation. Biopsy of Eustachian tube mucosa was obtained preoperative and 1â¯month post. Recurrence ratio and Eustachian tube scores (ETS) were used to evaluate the effect of treatments. RESULTS: All patients showed narrowed with edematous and thickened Eustachian tube mucosa. At 1â¯month post-treatment, BET with methylprednisolone irrigation significantly decreased intraepithelial inflammation and restored the quality of epithelium and cilia. For group II to IV, The recurrence rate was significantly lower in group IV compared with the other two, but only significantly lower in group IV VS group II at 3â¯months and 6â¯months, no significant difference at 12â¯months. The recurrence rate was significantly higher in group I during follow-up. The ETS were improved in group II, III and IV after treatment. At 1â¯month and 3â¯months posttreatment, group IV had significant higher ETS compared with other groups (Pâ¯<â¯0.05). There was no serious complications occurred. CONCLUSION: Methylprednisolone irrigation could help to recover mucosal function. BET and tympanic paracentesis with methylprednisolone irrigation could be regarded as a good choice for COME in adults, which has less recurrence rate and prompt recovery of ET function.

We conducted a retrospective chart review to characterize the outcomes of 12 patients-9 men and 3 women, aged 21 to 79 years (mean: 49)-who had been treated at our tertiary care center for acute bacterial meningitis caused by acute otitis media (ABMAO). Fever was the most common presenting sign/symptom, observed in 8 patients, followed by otalgia, neck stiffness, headache, and confusion. An opaque and bulging tympanic membrane was observed in 8 patients. Cultures were positive for Streptococcus pneumoniae in the cerebrospinal fluid, ear, and blood in 7, 5, and 3 patients, respectively. Immediate treatment included tympanocentesis, with aspirates sent for bacteriologic cultures. Seven patients (58.3%) underwent surgery; 5 were operated on early, and 2 underwent surgery at a later stage because of a suspected defect in the mastoid bone. A cortical mastoidectomy was performed in 6 of the 7 surgical patients; the remaining patient underwent a canal-wall-down procedure. Ten patients experienced a full recovery, 1 died, and 1 had a poor neurologic outcome (vegetative state); both of the latter 2 patients were older than 60 years. We conclude that early diagnosis, administration of antibiotics, and myringotomy are crucial for control of ABMAO. A cortical mastoidectomy with ventilation tube insertion can be reserved for patients who do not respond, which is common.

BACKGROUND: Acute mastoiditis (AM) is a suppurative infection of the mastoid air cells, representing the most frequent complication of acute otitis media. AM remains an important entity in children due to its potential complications and sequelae. We aim to describe the cases of AM admitted at our department, identify risk factors potentially associated with complications and analyse the changes in clinical approach of AM over time. METHODS: Case review of clinical files of children admitted with acute mastoiditis from June 1996 to May 2013 at a Lisbon metropolitan area hospital. Data was divided into two groups (prior and after May 2005) in order to evaluate changes in AM approach over the years. RESULTS: 135 AM episodes were included. The median age was 3.8 years and 42% children were less than 24 months of age. Symptoms at presentation included fever (69%), ear pain (56%) and otorrhea (40%). Complications occurred in 22% patients and were more common in children under 24 months (33% vs 15%, p ≤ 0.01). Leukocyte count was significantly higher in children with complications (16.7 vs 14.5 × 109/µL, p ≤ 0.05) as was C-Reactive Protein value (13 vs 6.3 mg/dL, p ≤ 0.001). There was a significant association between the development of complications and C-Reactive Protein value at admission (OR 1.892; IC95%: 1.018-2.493, p ≤ 0.01). The optimal cut-off value was 7.21 mg/dL. Over time there was a significant increase in middle ear cultures obtained by tympanocentesis during surgery (2% vs 16%, p ≤ 0,01) and also a decrease in the use of broad spectrum antibiotherapy as initial treatment (52% vs 25%,p ≤ 0,001). CONCLUSIONS: Children under 24 months, with high leukocyte count or with high C-Reactive Protein value should be monitored closely since complications tend to be more frequent. A CRP value of 7.21 mg/dL at admission seems to be a good cut-off to monitor children for potential complications. Throughout the period analysed more cultures were performed allowing identification of the pathogens and implementation of appropriate antibiotic therapy.

Pneumococcal conjugate vaccines (PCVs) have substantially reduced the burden of pneumococcal disease, including the incidence of otitis media (OM). However, in most countries, no surveillance exists to monitor the change in pneumococcal OM incidence after the introduction of PCVs. We explored whether measuring pneumococcal carriage was a useful surrogate for monitoring postvaccination changes in the incidence of pneumococcal OM. The 7-valent PCV was introduced to Israel's national immunization program in July 2009 and gradually replaced by the 13-valent PCV starting in November 2010. Each day since 2009, nasopharyngeal swabs have been obtained from the first 4 Bedouin children and the first 4 Jewish children who were younger than 5 years old and attended a pediatric emergency room in southern Israel. During the same time, OM surveillance in southern Israel included all children younger than 2 years of age who were diagnosed with OM and had undergone a middle-ear fluid culture. The relative change in the prevalence of vaccine-serotype (VT) pneumococcal carriage was predictive of the relative change in incidence of OM due to VT pneumococcus. However, the serotype replacement observed in non-VT carriage is not paralleled in the incidence of OM due to non-VT pneumococcus. This could indicate that there are more complex mechanisms of the immune response involved in preventing initial and consecutive episodes of OM, which has been changed through declining prevalence of the most virulent serotypes as a result of vaccination.

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