Abstract
Background Tympanometry is used as part of a battery of tests for screening of middle ear function and may help diagnose middle ear disorders, but remains available only on expensive test equipment. Methods We report a low-cost smartphone-based tympanometer system that consists of a lightweight and portable attachment to vary air pressure in the ear and measure middle ear function. The smartphone displays a tympanogram and reports peak acoustic admittance in realtime. Our programmable and open-source system operates at 226 Hz and was tested on 50 pediatric patient ears in an audiology clinic in parallel with a commercial tympanometer. Results Our study shows an average agreement of 86 ± 2% between the 100 tympanograms produced by the smartphone and commercial device when five pediatric audiologists classified them into five classes based on the Liden and Jerger classification. Conclusion Given the accessibility and prevalence of budget smartphones in developing countries, our open-source tool may help provide timely and affordable screening of middle ear disorders. Tympanometry is a test used to evaluate the health of the middle ear, which is involved in hearing, and helps in diagnosing middle ear disorders. However, the test currently requires expensive equipment and is limited in availability in resource-constrained settings. We present a low-cost smartphone-based tympanometry system. The device is able to change the air pressure of the ear canal and measure ear drum mobility. Our system, for which the software and hardware are openly available, is tested in 50 ears from children attending an audiology clinic. A panel of pediatric audiologists classified tympanometry measurements from our device and a commercial tympanometer with good agreement. Given the increasing availability of smartphones in developing countries, our system has the potential to make screening of middle ear disorders more accessible. Chan et al. develop an open-source smartphone-based tympanometer to evaluate middle ear function. The authors test their device in a group of paediatric patients at an audiology clinic and report a high level of agreement in audiologists’ classification of tympanograms produced using this device compared with a commercial device.

Abstract
The tympanic membrane (TM) undergoes a number of pathological changes in middle ear disease which can be detected by a video-otoendoscope. Middle ear disease is also accompanied by changes in middle ear pressure which can be assessed by tympanometry. The objectives of this study were to find the correlation between video-otoendoscopy and tympanometry in acute middle ear infections and to deduce which of the two is more efficient and reliable for early diagnosis. 75 patients with AOM or OME were included over 1 year where each patient was followed for 21 days. Detailed history and clinical examination with videootoendoscope and tympanometry was done on each visit. Each TM was graded using OMGRADE scale. Symptoms and clinical findings consistent with acute otitis media were given a clinical score (CO Score). The results were collected and correlation between video-otoendoscopy and tympanometry was determined and their individual sensitivity, specificity and diagnostic accuracy was calculated. The sensitivity, specificity and diagnostic accuracy for tympanometry and video-otoendoscopy was calculated individually for each of the 4 visits and positive correlation between the 2 was found. Our study showed that tympanometry had a higher overall sensitivity than video-otoendoscopy. While, video-otoendoscopy showed a higher specificity than Tympanometry. Otoendoscopy is good for ruling out AOM/OME but cannot rule out persisting Middle Ear Effusion and Tympanometry is a better tool for detecting MEE but cannot differentiate well between AOM and OME. We found that tympanometry plus otoendoscopy together greatly increase the chances of detecting AOM and OME thus improving diagnostic accuracy, reducing financial costs associated with over or mis-diagnosis.

Abstract
INTRODUCTION Reaching the point of treatment failure in the management of pediatric acute otitis media (AOM) is decision-changing, and is often associated with switching to a broader coverage antibiotic with/without middle ear surgical drainage. Yet, still there is no consensus on the definition of what is treatment failure, which may lead to confusion for clinical decision-making purposes. We sought to review the heterogeneity of treatment failure definitions in AOM. METHODS We searched for relevant English language manuscripts using the following key-words: ['otitis media' (OM) or (AOM)] AND ['treatment failure' or 'failure' or 'response failure' or 'response'] AND 'human' in various electronic databases from 1/1/2005 through 10/31/2020. RESULTS In the 60 retrieved papers, treatment failure was considered only when antibiotics had been prescribed beforehand, but not when watchful waiting had been adopted. We categorized the manuscripts into 5 major treatment failure definition subgroups, which occasionally overlapped: unimprovement or worsening of symptoms or signs of failure in otoscopy (n = 36), specialist(s) referral or hospital admission (n = 12), changing or adding antibiotic treatment (n = 22), failure to eradicate causative bacteria (n = 7) and failure as perceived by parents (n = 4). CONCLUSIONS We suggest a broader definition of AOM treatment failure including physical examination findings and degree of initial treatment response, which will enable an unbiased, uniform comparison of treatments for pediatric AOM.

Abstract
OBJECTIVES Otitis media with effusion (OME) is an important clinical entity because of its high prevalence, difficulties in diagnosis, complications and diversities in management. Herein, we aimed to evaluate current physician approaches on OME and determine clinical adherence to current guidelines. METHODS AND MATERIALS A total of 370 physicians [Group 1: pediatricians (n = 256, 69.2%), Group 2: otorhinolarynologists (n = 114, 30.8%)] completed a survey instrument addressing demographic data and clinical practice parameters on OME in children. We also compared clinical approaches of Group 1 and Group 2. In addition, multiple logistic regression analysis was performed to evaluate factors which may effect correct approaches. RESULTS The mean period of clinical experience was 9.30 ± 8.35 [median 6 (1-40)] years. A total of 311 (84%) respondents reported satisfactory level of self-confidence as regards of clinical approaches to OME. Reduced mobility of the tympanic membrane and preference of pneumatic otoscopy was signified by 107 (28.9%) and 64 (17.3%) respondents, respectively. Fifty-six (15.1%) physicians identified "watchful waiting" for 3 months for children who are not at risk while 314 (84.9%) reported preference of medications, with antibiotics the most preferred prescription (n = 223, 63%). Comparison of Group 1 and Group 2 indicated similar results except better, yet insufficient, characterization of physical examination findings of OME by Group 2 (p < 0.001, for each parameter). Group 2 preferred tympanometry more in uncertain cases (p < 0.001) and handled chronic cases better (p < 0.001). Multiple logistic regression analysis revealed lower signification of reduced mobility of the tympanic membrane for respondents who denoted depending on personal experience ([OR] = 3.077 [95% CI 1.042-9.09]) or following clinical guidelines ([OR] = 3.365 [95% CI 1.38-8.20]) rather than combining them both. Rate of antibiotic avoidance was lowest in physicians with a period of clinical experience<5 years ([OR] = 2.14 [95% CI 1.32-3.48]). CONCLUSIONS Despite notifying high self-confidence and adherence to current guidelines on OME, both pediatricians and otorhinolaryngologists lacked to exhibit proper approaches. Further research is warranted to evaluate the causes of poor adherence to current guidelines and bring suggestions for the maintenance of consistent and correct clinical approaches to OME.

Abstract
Introduction: Implementation of pediatric telemedicine has been emphasized. We examined whether parents could perform smartphone otoscopy for the diagnosis of otitis media. Materials and Methods: We included children (6-35 months) attending day care with at least one episode of acute otitis media (AOM) within 90 days of the study entry. The timing for a teaching intervention was randomized. In the immediate teaching group, parents were taught smartphone otoscopy and cerumen was removed at the first visit. The delayed teaching group received the teaching intervention after 1 week's independent use. During the 60 study days, parents performed home examinations. The main outcome, the diagnostic quality of the tympanic membrane videos to determine healthy ear, otitis media with effusion (OME) and AOM diagnoses was measured with a structured video analysis independently by three physicians. Parents' experience was measured with a questionnaire. Results: AOM could be detected or excluded in 87% (609/699) of the videos during acute symptoms. After the teaching intervention, healthy ear, OME, or AOM could be diagnosed in 40% (521/1,293) of the videos. During the first week's intervention, one of the three diagnoses was attained in 33% (50/153) and in 12% (22/179) of the videos in the immediate and delayed teaching group, respectively (p < 0.001). The performance of the smartphone otoscopy examination was easy in 85% (35/41) of families. Discussion: After been taught, parents are able to perform smartphone otoscopy for the remote detection or exclusion of AOM. Conclusions: Future studies should assess the clinical usefulness of parent-performed smartphone otoscopy.

Abstract
BACKGROUND Acute otitis media (AOM) induces middle-ear effusion (MEE), which affects hearing. The effect of antimicrobial treatment on the resolution of MEE is controversial, and the factors that affect resolution are unknown. METHODS We studied the effect of antimicrobial treatment on the time to the resolution of MEE as a secondary objective in our randomized double-blind placebo-controlled trial. Children aged 6 to 35 months with stringently diagnosed AOM were allocated to receive amoxicillin-clavulanate (161 patients) or placebo (158 patients) for 7 days and closely followed for 3 months. This study was registered at ClinicalTrials.gov (identifier NCT00299455). RESULTS The median times to resolution of MEE were 20 days (95% confidence interval [CI], 16-24 days) and 29 days (95% CI, 26-32 days) in the amoxicillin-clavulanate and placebo groups, respectively (P = .10). The resolution of MEE was confirmed in 138 (86%) of 161 and 132 (84%) of 158 patients in the amoxicillin-clavulanate and placebo groups, respectively (P = .59). In multivariable analysis, the resolution of MEE was prolonged most significantly by at least 1 recurrence of AOM during follow-up. MEE resolved in 65 (65%) of 100 patients with a recurrence of AOM during follow-up and in 205 (94%) of 219 of those without a recurrence (P < .001) (median times to resolution, 67 vs 15 days, respectively; P < .001). CONCLUSIONS Immediate antimicrobial treatment of AOM does not significantly affect the resolution of MEE in young children. Subsequent recurrences of AOM are a major reason for the persistence of MEE.

Abstract
CONTEXT Childhood acute otitis media (AOM) is highly prevalent. Its usual sequela of middle ear effusion (MEE) can lead to conductive hearing loss, for which surgery is commonly used. OBJECTIVE To evaluate the efficacy of an osteopathic manipulative treatment (OMT) protocol on MEE resolution following an episode of AOM. The authors hypothesized that OMT provided adjunctively to standard care for young children with AOM would reduce the duration of MEE following the onset of AOM. METHODS We compared standard care only (SCO) and standard care plus OMT (SC+OMT) for the duration of MEE following AOM. Patients were aged 6 months to 2 years. The SC+OMT group received OMT during 3 weekly visits. Weekly tympanometric and acoustic reflectometer (AR) readings were obtained from all patients. RESULTS There were 52 patients enrolled, with 43 completing the study and 9 dropping out. No demographic differences were noted. Only ears from each patient with abnormal tympanograms at entry were included. There were 76 ears in the tympanogram analysis (38 from SCO; 38 from SC+OMT) and 61 ears in the AR data analysis (31 from SCO; 30 from SC+OMT). Dependence of bilateral ear disease noted in AR readings was accounted for in statistical analysis. Tympanogram data demonstrated a statistically significant improvement in MEE at visit 3 in patients in the SC+OMT group (odds ratio, 2.98; 95% confidence interval, 1.16, 7.62; χ(2) test for independence, P=.02). The AR data analysis showed statistically significant improvement at visit 3 for the SC+OMT group (z=2.05; P=.02). There was no statistically significant change in MEE before or immediately after the OMT protocol. CONCLUSION A standardized OMT protocol administered adjunctively with standard care for patients with AOM may result in faster resolution of MEE following AOM than standard treatment alone.

Abstract
OBJECTIVE Tympanometry can be used to detect middle ear effusion (MEE). As the need for rearrangement of clinical resources at the primary care level increases, it is important to determine whether layman parents could be taught to use the tympanometer reliably, aiming to reduce unnecessary physician visits during respiratory tract infections. METHODS From our AOM treatment trial we enrolled 78 children (age 6-35 months) who had persistent MEE, parents were voluntary and willing to use a tympanometer at home, the child was sufficiently co-operative, and parents learned technically the use of the tympanometer. At home, parents were asked to perform daily bilateral tympanometry on their child. We included those parental tympanometric examinations, to which the corresponding tympanometric examination, within one day by a study physician was available. Parental tympanometric examinations were compared to the pneumatic otoscopy by a study physician which served as the diagnostic standard. RESULTS This study involved 78 children and a total of 432 parental tympanometric examinations. From these 432 examinations, parents obtained an interpretable tympanogram in 83% (359/432) and physicians in 91% (393/432) (absolute rate difference 8%, 95% CI 3-12%). Both obtained an interpretable tympanogram from the same ear in 75% (326/432) of the tympanometric examinations. Of these 326 interpretable examinations, parents and physicians were in accordance with either a peaked or a flat tympanogram in 88% of examinations (288/326) (kappa-value 0.77). When the tympanogram was peaked, pneumatic otoscopy indicated healthy middle ear in 72% (122/169) of parental and in 69% (149/217) of study physicians' tympanometric examinations (absolute rate difference 4%, 95% CI -6% to 13%). When the tympanogram was flat, pneumatic otoscopy indicated any MEE in 92% of parental (174/190) and in 96% (169/176) of study physicians' tympanometric examinations (absolute rate difference 4%, 95% CI -9% to 1%). CONCLUSION This study showed that layman parents are able to use tympanometry technically successfully, and that the parental tympanometric examinations are as reliable as those obtained by study physicians.

Abstract
Objectives Recently, new evidence-based recommendations have been introduced for diagnosing and managing otitis media with effusion (OME) in children. However, there are some difficulties to follow the general guidelines in the tertiary hospitals. The purpose is to evaluate the efficiency of antibiotics or antihistamines for treatment of children with OME in the tertiary hospital with a randomized prospective clinical study. Methods Eighty-four children with OME who had been diagnosed in the tertiary hospital were randomized to receive 5 different medications for 2 weeks. We prescribed antibiotics (amoxicillin-clavulanate syrup) in Group I (n=16), antibiotics/steroids (prednisolone) in Group II (n=18), antibiotics/antihistamines (ebastine) in Group III (n=15), antibiotics/steroids/antihistamines in Group IV (n=17), and mucolytics (ivy leaf extract) in Group V (n=17) for control. We followed-up children every 2 weeks and evaluated the state of OME at 3 months. Results Thirty six (42.9%) of 84 children were resolved within average 6.9 weeks after the treatments. Thirty-six (42.9%) were treated with ventilation tube insertion and 12 patients (14.3%) were observed. There was no difference in the resolution rates of OME among the five different protocols (P>0.05). There was no difference in the resolution rates among groups who used steroids, antihistamines, steroids and antihistamines, or other medications to manage 42 children with allergies (P>0.05). Conclusion In the tertiary hospital, the cure rate of children with OME was not as high as well-known, and antibiotics or anti-allergic medications were not more effective than control. We may, therefore, need any other guidelines which are different from the previous evidence-based recommendations, including early operation in the tertiary hospitals.

Abstract
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.

Abstract
Sinusitis, acute otitis media and tonsillitis are very frequent in children. Most of these infections are caused by viruses, but are generally treated with antibiotics. Inappropriate use of antibiotics favors the selection, growth and spread of resistant bacteria; these bacteria colonize the airways and affect the entire community. With the emergence of antibiotic-resistant bacteria, respiratory infections have become more difficult to treat. Effective strategies are needed to restrict the use of antibiotics without harming children that truly need these drugs. Aim to present a critical analysis of the results of randomized and controlled studies on clinical and laboratory criteria used in diagnosing and treating tonsillitis, sinusitis and otitis. Methods a review of randomized and controlled studies about these conditions published in MEDLINE and SCIELO from 2000 to 2006. Conclusions Given that most of these infections progress favorably without antibiotics, the use of these drugs should be avoided unless the child belongs to a high risk group for complications, or symptoms persist or worsen with despite symptomatic treatment. Physicians and laypersons should have better knowledge about the natural evolution of acute respiratory infections.

Abstract
The "wait and see" approach in acute otitis media (AOM), consisting of postponing the antibiotic administration for a few days, has been advocated mainly to counteract the increased bacterial resistance in respiratory infections. This approach is not justified in children less than 2 years of age and this for several reasons. First, AOM is an acute inflammation of the middle ear caused in about 70% of cases by bacteria. Redness and bulging of the tympanic membrane are characteristic findings in bacterial AOM. Second, AOM is associated with long-term dysfunction of the inflamed eustachian tube (ET), particularly in children less than 2 years of age. In this age group, the small calibre of the ET together with its horizontal direction result in impaired clearance, ventilation and protection of the middle ear. Third, recent prospective studies have shown poor long-term prognosis of AOM in children below 2 years with at least 50% of recurrences and persisting otitis media with effusion (OME) in about 35% 6 months after AOM. Viruses elicit AOM in about 30% of children. A prolonged course of AOM has been observed when bacterial and viral infections are combined because viral infection is also associated with ET dysfunction in young children. Bacterial and viral testing of the nasopharyngeal aspirate is an excellent tool both for initial treatment and recurrence of AOM. Antibiotic treatment of AOM is mandatory in children less than 2 years of age to decrease inflammation in the middle ear but also of the ET particularly during the first episode. The best choice is amoxicillin because of its superior penetration in the middle ear. Streptococci pneumoniae with intermediary bacterial resistance to penicillin are particularly associated with recurrent AOM. Therefore the dosage of amoxicillin should be 90 mg/kg per day in three doses. In recurrent AOM with beta-lactamase-producing bacilli, amoxicillin should be associated with clavulanic acid at a dose of 6.4 mg/kg per day. The duration of the treatment is not established yet but 10 days is reasonable for a first episode of AOM. OME may be a precursor initiating AOM but also a complication thereof. OME needs a watchful waiting approach. When associated with deafness for 2-3 months in children over 2 years of age, an antibiotic should be given according to the results of the bacterial resistance in the nasopharyngeal aspirate. The high rate of complications of tympanostomy tube insertion outweighs the beneficial effect on hearing loss. The poor results of this procedure are due to the absence of effects on ET dysfunction. Pneumococcal vaccination has little beneficial effects on recurrent AOM and its use in infants needs further studies. Treatment with amoxicillin is indicated in all children younger than 2 years with a first episode of AOM presenting with redness and bulging of the tympanic membrane. Combined amoxicillin and clavulanic acid should be given in patients with beta-lactamase-producing bacteria. The duration of treatment is estimated to be at least 10 days depending on the findings by pneumo-otoscopy and tympanometry. Bacterial and viral testing of the nasopharyngeal aspirate is highly recommended particularly in children in day care centres as well as for regular follow-up. The high recurrence rate is due to the long-lasting dysfunction of the eustachian tube and the immune immaturity of children less than 2 years of age.
