Abstract
OBJECTIVES Otitis media with effusion (OME) is characterized by the presence of fluid in the middle ear without the presentation of signs or symptoms of acute ear infection. The point prevalence of OME reaches as high as 60% in children younger than 2 years of age. We used the National Health Insurance Research Database (NHIRD) to investigate the use of medication in children with OME before receiving ventilation tube insertion (VTI). METHODS Data of pediatric patients (age ≤ 12 years) who had OME and received VTI from January 1, 2011, to December 30, 2012, were retrieved from the Taiwan NHIRD. We surveyed the use of 4 medications to understand whether health care providers achieved the standards of medication use recommended by clinical practice guidelines. RESULTS This study examines the factors affecting the use of medication for pediatric OME. Overall, according to the study's operational definitions, the use of systemic antibiotics was most common (59.9%), followed by systemic antihistamines (23.4%), systemic steroids (8.8%), and intranasal steroids (9.6%). Systemic antibiotics use was associated with 12 factors. Ten of the 12 factors increase the use of systemic antibiotics, including namely age (age > 2 years), comorbidities, teaching hospital, and community hospital. In contrast, namely catastrophic illness and watchful waiting are the 2 factors that decrease systemic antibiotics use. For the use of systemic antihistamines, systemic steroids, and intranasal steroids were related to 6, 5, and 2 factors, respectively. CONCLUSIONS The rate of drug use differs from the rate of use recommended by commonly used clinical practice guidelines. We found that the higher the number of factors that influenced the patients' drug use, the higher the rate of drug use. According to these results, drafting a treatment guideline for OME patients in accordance with current clinical practices in Taiwan is highly recommended.

Abstract
OBJECTIVES This study aims to investigate the inter-rater reliability and agreement of the diagnosis of otitis media with effusion, acute otitis media, and no effusion cases based on an otoscopy image and in some cases an additional wideband tympanometry measurement of the patient. METHODS 1409 cases were examined and diagnosed by an otolaryngologist in the clinic, and otoscopy examination and wideband tympanometry (WBT) measurement were conducted. Afterwards, four otolaryngologists (Ear, Nose, and Throat doctors, ENTs), who did not perform the acute examination of the patients, evaluated the otoscopy images and WBT measurements results for diagnosis (acute otitis media, otitis media with effusion, or no effusion). They also specified their diagnostic certainty for each case, and reported whether they used the image, wideband tympanometry, or both, for diagnosis. RESULTS All four ENTs agreed on the diagnosis in 57% of the cases, with a pairwise agreement of 74%, and a Light's Kappa of 0.58. There are, however, large differences in agreement and certainty between the three diagnoses. Acute otitis media yields the highest agreement (77% between all four ENTs) and certainty (0.90), while no effusion shows much lower agreement and certainty (34% and 0.58, respectively). There is a positive correlation between certainty and agreement between the ENTs across all cases, and both certainty and agreement increase for cases where a WBT measurement is shown in addition to the otoscopy image. CONCLUSIONS The inter-rater reliability between four ENTs was high when diagnosing acute otitis media and lower when diagnosing otitis media with effusion. However, WBT can add valuable information to get closer to the ground-truth diagnosis without myringotomy. Furthermore, the diagnostic certainty increases when the WBT is examined together with the otoscopy image.

Abstract
Wideband acoustic immittance (WAI) noninvasively assesses middle ear function by measuring the sound conduction over a range of audible frequencies. Although several studies have shown the potential of WAI for detecting the presence of middle ear effusions (MEEs), determining the effects of MEE type and amount on WAI in vivo has been challenging due to the anatomical location of middle ear cavity. The purpose of this study is to correlate WAI measurements with physical characteristics of the middle ear and MEEs determined by optical coherence tomography (OCT), a noninvasive optical imaging technique.

Abstract
Decreased mobility of the human eardrum, the tympanic membrane (TM), is an essential indicator of a prevalent middle ear infection. The current diagnostic method to assess TM mobility is via pneumatic otoscopy, which provides subjective and qualitative information of subtle motion. In this study, a handheld spectral-domain pneumatic optical coherence tomography system was developed to simultaneously measure the displacement of the TM, air pressure inputs applied to a sealed ear canal, and to perform digital pneumatic otoscopy. A novel approach based on quantitative parameters is presented to characterize spatial and temporal variations of the dynamic TM motion. Furthermore, the TM motions of normal middle ears are compared with those of ears with middle ear infections. The capability of noninvasively measuring the rapid motion of the TM is beneficial to understand the complex dynamics of the human TM, and can ultimately lead to improved diagnosis and management of middle ear infections.

Abstract
In this study, we propose an automatic diagnostic algorithm for detecting otitis media based on otoscopy images of the tympanic membrane. A total of 1336 images were assessed by a medical specialist into three diagnostic groups: acute otitis media, otitis media with effusion, and no effusion. To provide proper treatment and care and limit the use of unnecessary antibiotics, it is crucial to correctly detect tympanic membrane abnormalities, and to distinguish between acute otitis media and otitis media with effusion. The proposed approach for this classification task is based on deep metric learning, and this study compares the performance of different distance-based metric loss functions. Contrastive loss, triplet loss and multi-class N-pair loss are employed, and compared with the performance of standard cross-entropy and class-weighted cross-entropy classification networks. Triplet loss achieves high precision on a highly imbalanced data set, and the deep metric methods provide useful insight into the decision making of a neural network. The results are comparable to the best clinical experts and paves the way for more accurate and operator-independent diagnosis of otitis media.

Abstract
INTRODUCTION The Italian Guideline for the management of acute otitis media (AOM) in children has been recently updated. We conducted a cross-sectional survey to investigate the adherence of Italian primary care paediatricians to the guideline recommendations. METHODS A questionnaire including 13 closed-ended questions was administered to the paediatricians participating in the 24th National Congress of Practical Pediatrics, held in Florence in November 2019. The answers were collected and analyzed. RESULTS Eight hundred fifty-four out of 1000 questionnaires were collected (85.4%). Most of the participants declared that they did not remove the cerumen (63.9%). Pneumatic otoscope and tympanometry were routinely used by a minority of paediatricians (9.6% and 3.9%, respectively); all the participants declared to routinely prescribe oral analgesic drugs and 97.6% of them considered amoxicillin or amoxicillin/clavulanic acid as the first-choice antibiotic. In an uncomplicated unilateral AOM case, the preferred strategy was immediate antibiotic therapy in children under two years of age (83.1%) and watchful waiting in those >2 years (77.3%). Oral amoxicillin was most commonly prescribed at the 80-100 mg/kg/day (56.6%), in 3 daily doses (87.7%), while amoxicillin/clavulanic acid was equally prescribed at 80-100 or 50 mg/kg/day (47.1%-48.5%), mainly in 2 doses (58.6%). However, both drugs are recommended at a dosage of 80-90 mg/kg/day (calculated on amoxicillin), in 3 daily doses. Although the Guideline recommends ten days of therapy, both drugs were most commonly prescribed for 7-8 days (55.5%-57.7%). Pneumococcal and flu vaccines were recommended only by 41.6% and 31.6% of participants, respectively. CONCLUSIONS Our data suggest adequate adherence of the guideline recommendations considering the preferred antibiotic drug, pain management and the choice between immediate antibiotic therapy and watchful waiting. Conversely, targeted training programs are needed to improve adherence to recommendations on cerumen removal, use of pneumatic otoscopy, correct use of antibiotics in terms of optimal dosage, duration and number of daily administrations, and to implement proper AOM prevention strategies.

Abstract
Pneumatic otoscopy is the recommended diagnostic method for middle ear infections. Physicians use a pneumatic otoscope to assess the position of the eardrum (bulging or retraction) as well as the eardrum mobility while an insufflation bulb is squeezed to generate air pressure changes in a sealed ear canal. While pneumatic otoscopy provides increased sensitivity and specificity by detecting decreased eardrum mobility, there exist many challenges to correctly perform and interpret results. For example, the ear canal must be sealed using a specialized ear speculum to deliver sufficiently large pressure changes that can induce visible movements of an eardrum. To overcome this challenge, video motion magnification is proposed to amplify pneumatic-induced motions of the eardrum without sealing of the ear canal. Pneumatic otoscopy is performed on adult subjects using a smartphone camera with an otoscope attachment at 60 frames per second, with pressure inputs at 5 Hz. Phase-based Eulerian motion magnification is applied to magnify spatiotemporal dependent motions in the video. As a result, the motion magnification of unsealed pneumatic otoscopy reveals comparable eardrum motions as in standard pneumatic otoscopy with a sealed ear canal. Furthermore, the estimated motions (in pixels) are quantified to examine the spatial and the temporal variations of the eardrum motions. The motion magnification may avoid the need for sealing the ear canal as well as decrease patient discomfort in pneumatic otoscopy, improving the capability and the usability as a point-of-care diagnostic tool in primary care and otology.

Abstract
OBJECTIVE To perform a comprehensive review of otitis media microbiome literature published between 1st July 2015 and 30th June 2019. DATA SOURCES PubMed database, National Library of Medicine. REVIEW METHODS Key topics were assigned to each panel member for detailed review. Draft reviews were collated and circulated for discussion when the panel met at the 20th International Symposium on Recent Advances in Otitis Media in June 2019. The final draft was prepared with input from all panel members. CONCLUSIONS Much has been learned about the different types of bacteria (including commensals) present in the upper respiratory microbiome, but little is known about the virome and mycobiome. A small number of studies have investigated the middle ear microbiome; however, current data are often limited by small sample sizes and methodological heterogeneity between studies. Furthermore, limited reporting of sample collection methods mean that it is often difficult to determine whether bacteria detected in middle ear fluid specimens originated from the middle ear or the external auditory canal. Recent in vitro studies suggest that bacterial interactions in the nasal/nasopharyngeal microbiome may affect otitis media pathogenesis by modifying otopathogen behaviours. Impacts of environmental pressures (e.g. smoke, nutrition) and clinical interventions (e.g. vaccination, antibiotics) on the upper respiratory and middle ear microbiomes remain poorly understood as there are few data. IMPLICATIONS FOR PRACTICE Advances in understanding bacterial dynamics in the upper airway microbiome are driving development of microbiota-modifying therapies to prevent or treat disease (e.g. probiotics). Further advances in otitis media microbiomics will likely require technological improvements that overcome the current limitations of OMICs technologies when applied to low volume and low biomass specimens that potentially contain high numbers of host cells. Improved laboratory models are needed to elucidate mechanistic interactions among the upper respiratory and middle ear microbiomes. Minimum reporting standards are critically needed to improve inter-study comparisons and enable future meta-analyses.
