INTRODUCTION
Although acute otitis media (AOM) is a very frequent illness in children, it remains unclear to what extent children with AOM benefit from antibiotics (ABX). This systematic review aimed to clarify this subject by including randomised clinical trials (RCTs) from the pneumococcal vaccine era only.
METHODS
We performed a systematic literature search in four databases from 1 January 2000 to 1 January 2019 for RCTs comparing ABX to placebo in patients with AOM. Pain was registered as the main outcome. Adverse events (AE), development of contralateral otitis media, tympanic membrane perforation, late AOM recurrence, abnormal tympanometry and time to resolution of middle ear effusion were registered as secondary outcomes.
RESULTS
Six publications based on five RCTs with 1,862 patients were included. The number needed to treat (NNT) to reduce pain varied from seven (pain at day 7-10) to 28 (pain at day 2-3). The NNT for preventing contralateral otitis was ten. AE were seen in every 13th patient treated with ABX.
CONCLUSIONS
ABX appears to have a limited effect on both primary and secondary outcomes compared with placebo. A substantial number of patients experienced AE. New RCTs are needed to further clarify the effect. Ideally, RCTs could be conducted in Danish general practices in collaboration with practicing ear, nose and throat specialists to obtain large unselected populations with high rates of vaccine coverage. Until more evidence is provided, ABX should be considered among children younger than two years of age with severe symptoms of AOM, i.e. fewer and affected well-being.

Meta-Analysis Review
BACKGROUND
Acute otitis media (AOM) is one of the most common diseases in early infancy and childhood. Antibiotic use for AOM varies from 56% in the Netherlands to 95% in the USA, Canada and Australia. This is an update of a Cochrane review first published in The Cochrane Library in Issue 1, 1997 and previously updated in 1999, 2005, 2009 and 2013.
OBJECTIVES
To assess the effects of antibiotics for children with AOM.
SEARCH METHODS
We searched CENTRAL (2015, Issue 3), MEDLINE (1966 to April week 3, 2015), OLDMEDLINE (1958 to 1965), EMBASE (January 1990 to April 2015), Current Contents (1966 to April 2015), CINAHL (2008 to April 2015) and LILACS (2008 to April 2015).
SELECTION CRITERIA
Randomised controlled trials (RCTs) comparing 1) antimicrobial drugs with placebo and 2) immediate antibiotic treatment with expectant observation (including delayed antibiotic prescribing) in children with AOM.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial quality and extracted data.
MAIN RESULTS
For the review of antibiotics against placebo, 13 RCTs (3401 children and 3938 AOM episodes) from high-income countries were eligible and had generally low risk of bias. The combined results of the trials revealed that by 24 hours from the start of treatment, 60% of the children had recovered whether or not they had placebo or antibiotics. Pain was not reduced by antibiotics at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01) but almost a third fewer had residual pain at two to three days (RR 0.70, 95% CI 0.57 to 0.86; number needed to treat for an additional beneficial outcome (NNTB) 20). A quarter fewer had pain at four to seven days (RR 0.76, 95% CI 0.63 to 0.91; NNTB 16) and two-thirds fewer had pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7) compared with placebo. Antibiotics did reduce the number of children with abnormal tympanometry findings at two to four weeks (RR 0.82, 95% CI 0.74 to 0.90; NNTB 11), at six to eight weeks (RR 0.88, 95% CI 0.78 to 1.00; NNTB 16) and the number of children with tympanic membrane perforations (RR 0.37, 95% CI 0.18 to 0.76; NNTB 33) and halved contralateral otitis episodes (RR 0.49, 95% CI 0.25 to 0.95; NNTB 11) compared with placebo. However, antibiotics neither reduced the number of children with abnormal tympanometry findings at three months (RR 0.97, 95% CI 0.76 to 1.24) nor the number of children with late AOM recurrences (RR 0.93, 95% CI 0.78 to 1.10) when compared with placebo. Severe complications were rare and did not differ between children treated with antibiotics and those treated with placebo. Adverse events (such as vomiting, diarrhoea or rash) occurred more often in children taking antibiotics (RR 1.38, 95% CI 1.19 to 1.59; number needed to treat for an additional harmful outcome (NNTH) 14). Funnel plots do not suggest publication bias. Individual patient data meta-analysis of a subset of included trials found antibiotics to be most beneficial in children aged less than two years with bilateral AOM, or with both AOM and otorrhoea.For the review of immediate antibiotics against expectant observation, five trials (1149 children) from high-income countries were eligible and had low to moderate risk of bias. Four trials (1007 children) reported outcome data that could be used for this review. From these trials, data from 959 children could be extracted for the meta-analysis of pain at three to seven days. No difference in pain was detectable at three to seven days (RR 0.75, 95% CI 0.50 to 1.12). One trial (247 children) reported data on pain at 11 to 14 days. Immediate antibiotics were not associated with a reduction in the number of children with pain (RR 0.91, 95% CI 0.75 to 1.10) compared with expectant observation. Additionally, no differences in the number of children with abnormal tympanometry findings at four weeks, tympanic membrane perforations and AOM recurrence were observed between groups. No serious complications occurred in either the antibiotic or the expectant observation group. Immediate antibiotics were associated with a substantial increased risk of vomiting, diarrhoea or rash compared with expectant observation (RR 1.71, 95% CI 1.24 to 2.36; NNTH 9).Results from an individual patient data meta-analysis including data from six high-quality trials (1643 children) that were also included as individual trials in our review showed that antibiotics seem to be most beneficial in children younger than two years of age with bilateral AOM (NNTB 4) and in children with both AOM and otorrhoea (NNTB 3).
AUTHORS' CONCLUSIONS
This review reveals that antibiotics have no early effect on pain, a slight effect on pain in the days following and only a modest effect on the number of children with tympanic perforations, contralateral otitis episodes and abnormal tympanometry findings at two to four weeks and at six to eight weeks compared with placebo in children with AOM. In high-income countries, most cases of AOM spontaneously remit without complications. The benefits of antibiotics must be weighed against the possible harms: for every 14 children treated with antibiotics one child experienced an adverse event (such as vomiting, diarrhoea or rash) that would not have occurred if antibiotics were withheld. Therefore clinical management should emphasise advice about adequate analgesia and the limited role for antibiotics. Antibiotics are most useful in children under two years of age with bilateral AOM, or with both AOM and otorrhoea. For most other children with mild disease in high-income countries, an expectant observational approach seems justified.

BACKGROUND
This study aimed to assess the quality of global guidelines or consensus statements for newborn and childhood hearing screening, as well as to compare various guidelines between other countries and China.
METHODS
A PROSPERO registered systematic review (number CRD42021242198) was conducted. Multiple electronic databases and government websites including PubMed, EMBASE, Web of Science, CENTRAL, Cochrane Library, and BMJ Best Practice were searched from inception until May 2021. The latest national and international guidelines, consensus statements, technical specifications, and recommendations regarding newborn or childhood hearing screening that were published in Chinese or English medical journals or elsewhere with the full version available online. The following information was extracted independently by two reviewers for comparative analysis: titles, authors, publication year, country, the source organization, and main key recommendations using systems for assigning the level of evidence and strength of recommendations. The quality of the guidelines was assessed by three independent reviewers using the Appraisal of Guidelines for Research and Evaluation, 2nd edition. Intraclass correlation coefficients (ICCs) were calculated to assess among-reviewer agreement.
RESULTS
We assessed 15 newborn and 6 childhood hearing screening guidelines, respectively. Most newborn guidelines recommend the 1-3-6 guidelines and pre-discharge screening; however, the specific screening times differ. 93.33% of newborn hearing guidelines recommend "primary screening-re-screening-diagnosis-intervention" for well-babies while 73.33% of the guidelines recommend "initial screening-diagnosis-intervention" for newborns in neonatal intensive care unit (NICU); 33.33% of the newborn hearing guidelines recommended initial screening coverage of > 95% while 46.66% did not mention it. Further, 26.66% of the newborn hearing guidelines recommended a referral rate to diagnosis within 4% while 60% did not mention it. Regarding childhood hearing screening guidelines, the screening populations differed across guidelines (age range: 0-9 years); most guidelines recommend pediatric hearing screening for all preschoolers. Only 50% of the guidelines specify screening and re-screening techniques, including pure-tone hearing screening, OAE, tympanometry, and others. The "Clarity of Presentation" domain achieved the highest mean score, and the lowest was "Editorial Independence" both in newborn and childhood guidelines. Overall score of newborn hearing screening guidelines ranged from 3 (2018 Europe) to 7 (2019 America), with an average score of 5.33. Average score of childhood hearing screening guidelines was 4.78, with the score ranging from 4 (2017 England, 2012 Europe, 2016 WHO) to 6.67 (2011 America). ICC analysis revealed excellent agreement across 21 guidelines (> 0.75).
CONCLUSIONS
These findings indicated newborn hearing screening guidelines had superior quality over childhood ones. Comparative analysis suggested that recommendations of the Chinese newborn and pediatric hearing screening protocols are consistent with the mainstream international opinion. Moreover, this analysis demonstrated that "Editorial Independence" and "Stakeholder Involvement" have the greatest opportunities for improvement. These results may help to advance the quality of hearing screening guidelines in clinical practice and guide evidence-based updates.

CoDAS 2016To verify which damages prematurity causes to hearing and language. (Review)
Review
PURPOSE
To verify which damages prematurity causes to hearing and language.
RESEARCH STRATEGIES
We used the decriptors language/linguagem, hearing/audição, prematurity/prematuridade in databases LILACS, MEDLINE, Cochrane Library and Scielo.
SELECTION CRITERIA
randomized controlled trials, non-randomized intervention studies and descriptive studies (cross-sectional, cohort, case-control projects).
DATA ANALYSIS
The articles were assessed independently by two authors according to the selection criteria. Twenty-six studies were selected, of which seven were published in Brazil and 19 in international literature.
RESULTS
Nineteen studies comparing full-term and preterm infants. Two of the studies made comparisons between premature infants small for gestational age and appropriate for gestational age. In four studies, the sample consisted of children with extreme prematurity, while other studies have been conducted in children with severe and moderate prematurity. To assess hearing, these studies used otoacoustic emissions, brainstem evoked potentials, tympanometry, auditory steady-state response and visual reinforcement audiometry. For language assessment, most of the articles used the Bayley Scale of Infant and Toddler Development. Most studies reviewed observed that prematurity is directly or indirectly related to the acquisition of auditory and language abilities early in life.
CONCLUSION
Thus, it could be seen that prematurity, as well as aspects related to it (gestational age, low weight at birth and complications at birth), affect maturation of the central auditory pathway and may cause negative effects on language acquisition.

Review
Otitis media with effusion (OME) affects approximately 80% of children due to the middle ear being flooded with fluids, though with no microbial infection manifestations. Multiple issues can drive recurring pediatric OME, such as environment-based issues, previous medical issues, inherited vulnerability from family, contact time at childcare institutes, passive smoking, and more than three siblings together with atopy or allergic rhinitis. If OME is not promptly addressed, this could eventually result in hearing impairment or loss, with consequent negative repercussions on the child's communicative and behavioral patterns. OME diagnosis within the clinic is possible, with hearing capacity being assessed pre- and post-therapy. Adenoid hypertrophy (AH) represents a typical causative factor for middle-ear conditions, stemming from mechanical or anatomical issues. Consequently, adenoid size is paramount when determining tympanometry types and ear fluids. This systematic review investigated PubMed, Medline, Cochrane Library, and Science Direct databases in order to retrieve knowledge related to this issue, adopting inclusion and exclusion criteria and maintaining review quality through the employment of the Assessment of Multiple Systematic Reviews (AMSTAR), the Newcastle-Ottawa tool, and the Axis scale. This systematic review analyzed a previous review article, six observation-based investigations, and three cross-sectional investigations. Previous randomized controlled trials (RCTs) were not found within previous literature, suggesting such scarcity in this research niche and thus warranting future RCT investigations based on this compelling research niche.

Review
PURPOSE
Identify the characteristics of the clinical audiological evaluation of individuals with Williams syndrome by means of a systematic literature review.
RESEARCH STRATEGIES
The following research question was initially determined: "What are the characteristics of clinical auditory assessment in individuals with Williams syndrome?". From this, a bibliographic search was conducted in four databases using the descriptors: Williams syndrome, Hearing loss, and Audiology.
SELECTION CRITERIA
Only full articles with evidence levels 1 or 2, published in Brazilian Portuguese or English, were selected.
DATA ANALYSIS
Results obtained in the auditory tests used in the clinical routine, namely: immittance test, pure-tone audiometry, otoacoustic emissions, and brainstem auditory evoked potential were analyzed.
RESULTS
Two hundred nine studies were found, but only 12 met the inclusion criteria for the study. It was possible to observe prevalence of type A tympanometry curve, which may occur with absence of acoustic reflexes, mild to moderate sensorineural hearing loss, affecting mainly the high frequencies, absent or less amplified otoacoustic emissions, and brainstem auditory evoked potential without retrocochlear alteration.
CONCLUSION
Cochlear impairment is common in individuals with Williams syndrome and the main disorders found in the hearing assessment in this population are absence of otoacoustic emissions and acoustic reflexes, as well as presence of mild to moderate sensorineural hearing loss, mainly in the high-frequency range, observed by audiometry.

Review
: Ménière's disease (MD) is a disease of the inner ear, presenting with episodes of vertigo, hearing loss, and tinnitus.The aim of this study is to examine the role of multifrequency tympanometry (MFT) in the diagnosis of MD. A systematic review of MEDLINE (via PubMed), Scopus, Google Scholar, and the Cochrane Library was performed, aligned with the PRISMA guidelines. Only studies that directly compare ears affected by Ménière's disease with unaffected or control ears were included. Random-effects model meta-analyses were performed. Seven prospective case-control studies reported a total of 899 ears, 282 of which were affected by Ménière's disease (affected ears-AE), 197 unaffected ears in patients with MD (UE), and 420 control ears (CE) in healthy controls. No statistically significant differences between the groups were observed regarding resonant frequency (RF). The pure tone audiometry average of the lower frequencies (PTA basic) was significantly greater in affected ears when compared with unaffected ears. The conductance tympanogram at 2 kHz revealed a statistically significantly greater G width of 2 kHz in the affected ears when compared to both unaffected and control ears, while control ears had a statistically significant lesser G width of 2 kHz compared to both the other two groups. MFT, and specifically G width at 2 kHz, could be an important tool in the diagnosis of MD.

Review
OBJECTIVE
To perform a systematic review to determine if a total score of ≥14.5 (mean score ≥ 2.1) on the ETDQ-7 accurately identifies patients with obstructive Eustachian tube dysfunction (OETD) on impedance tympanometry (peak compliance <0.2 mL or middle ear pressure of -100 daPa) or other objective measures of OETD.
METHODS
A systematic review without a meta-analysis was performed of studies in four electronic databases (Pubmed, Embase, Web of Science, and Scopus) that used the ETDQ-7 and at least one objective measure of OETD.
RESULTS
Six-hundred and fifty-two studies were identified in the initial literature search. Abstracts from 337 studies were screened, followed by full-text review of 61 studies, and qualitative synthesis of 12 studies. Tympanometry was used as an objective measure in ten studies. Eight of the 12 included studies had patient cohort selection bias. Eight studies administered the ETDQ-7 in cohorts of patients with or without OETD, already confirmed on tympanometry, and found a sensitivity of 91%-100% and specificity of 67%-100%. Four studies administered the ETDQ-7 to patients who had not previously undergone objective testing and found a sensitivity of 49%-80% and specificity of 24%-78%.
CONCLUSIONS
The ETDQ-7 is an important patient-reported outcome measure. However, based upon existing literature, the ETDQ-7 appears limited as a diagnostic tool for OETD or as an objective measure of Eustachian tube function.

Meta-Analysis Review
OBJECTIVES
This systematic review aimed to assess the clinical evidence supporting the use of herbal medicines (HMs) for the treatment of otitis media with effusion (OME).
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
MEDLINE, EMBASE, Cochrane Library, AMED, CINAHL and three trial registries were searched up to January 2015. We also searched five Korean medical databases (KoreaMed, RISS, OASIS, DBPIA and KISS) and three Chinese databases (CNKI, Wanfang and VIP).
STUDY ELIGIBILITY CRITERIA
This study included randomised clinical trials that reported the effects of HM for OME. The primary outcome was the complete resolution of OME at 2 or 3 months post randomisation. Secondary outcomes included the partial or complete resolution at all possible time points and hearing test. Three authors independently screened the titles and abstracts, selected studies and extracted the data relating to trial quality, characteristics and results.
RESULTS
A total of 2141 potentially relevant studies were identified, of which 17 randomised clinical trials met our inclusion criteria. Most were evaluated as having a high or unclear risk of bias. Tongqiao tablets, Tongqiao huoxue decoctions and Tsumura-Saireito were associated with a lower complete or partial resolution rate when compared with conventional medicines (CMs) (p=0.02, p=0.0001, and p=0.04, respectively), and similar outcomes were observed with Huanglong tonger pills, Erzhang decoctions and Shenling baizhu powder when combined with CM versus CM alone (p<0.00001, p=0.02, and p=0.05, respectively). Tongqiao huoxue decoction plus CM appeared to be more effective than CM in terms of improving the pure tone threshold levels (p=0.0007). Tsumura-Saireito was found to affect the proportion of patients with normalised tympanometry (p=0.03).
CONCLUSIONS
Despite some indications of potential symptom improvement, the evidence regarding the effectiveness and efficacy of HMs for OME is of poor quality and therefore inconclusive.

BACKGROUND
Current data suggest that approximately 466 million people (5.0%) of the world's population have disabling hearing loss, therefrom, 34 million children, impacting their quality of life. To provide estimates on the prevalence of hearing loss on a national level, we reviewed the epidemiological literature addressing hearing loss in children and adolescents living in Germany as an example for a Western country.
METHODS
We searched Medline, Web of Science, Cochrane Library, ScienceDirect and LIVIVO to identify published data. Furthermore, we manually searched websites of relevant institutions and journals not listed in electronically and searched for ongoing studies and/or not yet published data in clinicaltrials.gov . Study selection, data extraction, and methodological assessment were carried out by two reviewers.
RESULTS
In total, 11 reports provided data with sample sizes ranging from 310 up to more than 14 million children and adolescents. Prevalence data were collected by interviews (self-assessments), using pure-tone audiometry or the international classification of diseases (ICD-10) coding and ranged from 0.1 to 128 per 1000 children. Although the estimate of the prevalence of hearing loss goes down, when the threshold was raised, generating a comprehensive and coherent set of estimates proved challenging owing to clinical heterogeneity including variation in age, the study setting, the definition of hearing loss and the assessment method. Moreover, representativeness (external validity) was often impaired owing to estimates lacking currentness (i.e., referring to former West Germany) or selected (patient) data and may not be typical for a more general population.
CONCLUSIONS
In conclusions, this work raises public awareness of the high prevalence of hearing loss, highlights issues associated with epidemiological research and is of great importance for researcher and those who use epidemiological data to inform clinical and political decision making.
