The effect of platelet activating factor (PAF) was studied to elucidate its role in the pathogenesis of otitis media and sensorineural hearing loss. The PAF alone did not induce a reduction of ciliary activity of the cultured middle ear mucosa. However, a dose-dependent decrease in ciliary activity was observed in the presence of the medium containing both PAF and macrophages. Intravenous injection of PAF did not induce dysfunction of the mucociliary system or morphologic changes of epithelium in the tubotympanum, but cytoplasmic vacuolization and ballooning were observed in the inner ear within 1 hour after injection of PAF. In contrast, intratympanic injection of PAF induced mucociliary dysfunction and some pathologic changes in the tubotympanum. Intratympanic inoculation of PAF induced no pathologic findings in the inner ear. These results suggest that PAF is at least partially involved in the pathogenesis of certain middle ear diseases such as otitis media with effusion. Additionally, PAF might be involved in the pathogenesis of some types of unexplained sensorineural hearing loss.

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.

Otitis media with effusion will be observed in every fifth child admitted for adenoid surgery; in children with cleft palates the incidence is 50%. With adenoidectomy alone, normal hearing can be restored in 50% and improved in further 25% of the patients. Over a 12-year period 1,683 patients with otitis media with effusion were treated with adenoidectomy and with insertion of tympanostomy tubes in those cases where adenoidectomy proved to be ineffective. Since the tubes only substitute tubal function, recurrences have to be expected in more than 30% after spontaneous extrusion of the tubes. Of all recurrences, 93% occur within two years after tube insertion. With thorough follow-up and repeated insertion of tubes, deterioration of the middle ear can be avoided and hearing kept normal. Impaired bone conduction does not reflect inner ear damage, but will improve with ventilation of the middle ear. Infections occur in 15% (5% postoperatively, 10% later); persistent perforations in 2.5% and cholesteatoma in 0.9%.

Background: The Press Ganey (PG) Medical Practice Survey is a commonly used questionnaire for measuring patient experience in healthcare. Our objective was to evaluate the PG surveys completed by caregivers of children presenting for urgent care evaluation of acute respiratory infections (ARIs) to determine any correlation with receipt of antibiotics during their visit. Methods: We evaluated responses to the PG urgent-care surveys for encounters of children <18 years presenting with ARIs (ie, sinusitis, bronchitis, pharyngitis, upper respiratory infection, acute otitis media, or serous otitis media with effusion) within 9 University of Utah urgent-care centers. Scores could range from 0 to 100. Because the distributions of scores followed right- skewed distribution with a high ceiling effect, we defined scores as dissatisfied with their care (≤25th percentile) and satisfied with their care (scores >25th percentile). Univariate and multivariable generalized mixed-effects logistic regression was used to assess correlates of patient dissatisfaction. Random intercepts were included for each provider to account for correlation within the same provider. Separate models were used for each PG component score. Multivariable models adjusted for receipt of antibiotics, age, gender, race, ethnicity, and provider type. Results: Overall, 388 of 520 responses (74.6%) indicated satisfaction and 132 responses (25.4%) indicated dissatisfaction. Among patients who did not receive antibiotics, 87 of 284 responses (30.6%) indicated dissatisfaction versus 45 of 236 (19.1%) who did receive antibiotics. Among patients who were dissatisfied with their clinician, raw clinician PG scores were higher among patients who received antibiotics (mean, 64.5; standard deviation [SD], 16.9) versus those who did not receive antibiotics (mean, 54.7; SD, 24.4; P = .015) (Table 1). In a multivariable analysis, receipt of antibiotics was associated with a reduction in patient dissatisfaction overall (odds ratio, 0.55; 95% CI, 0.36–0.85). Conclusions: Overall, most responses for patients seen for ARIs in pediatric urgent care were satisfied. However, a significantly higher proportion of responses for patients who did not receive antibiotics were dissatisfied than for those patients who received antibiotics. Antibiotic stewardship strategies to communicate appropriate prescribing while preserving patient satisfaction are needed in pediatric urgent-care settings.Funding: NoneDisclosures: None
