Abstract
BACKGROUND Acute otitis media (AOM) is one of the most common diseases in childhood for which antibiotics are commonly prescribed; a systematic review reported a pooled prevalence of 85.6% in high-income countries. This is an update of a Cochrane Review first published in the Cochrane Library in 1997 and updated in 1999, 2005, 2009, 2013 and 2015. OBJECTIVES To assess the effects of antibiotics for children with AOM. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Current Contents, CINAHL, LILACS and two trial registers. The date of the search was 14 February 2023. SELECTION CRITERIA We included randomised controlled trials 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 screened trials for inclusion and extracted data using the standard methodological procedures recommended by Cochrane. Our primary outcomes were: 1) pain at various time points (24 hours, two to three days, four to seven days, 10 to 14 days), and 2) adverse effects likely to be related to the use of antibiotics. Secondary outcomes were: 1) abnormal tympanometry findings, 2) tympanic membrane perforation, 3) contralateral otitis (in unilateral cases), 4) AOM recurrences, 5) serious complications related to AOM and 6) long-term effects (including the number of parent-reported AOM symptom episodes, antibiotic prescriptions and health care utilisation as assessed at least one year after randomisation). We used the GRADE approach to rate the overall certainty of evidence for each outcome of interest. MAIN RESULTS Antibiotics versus placebo We included 13 trials (3401 children and 3938 AOM episodes) from high-income countries, which we assessed at generally low risk of bias. Antibiotics do not reduce pain at 24 hours (risk ratio (RR) 0.89, 95% confidence interval (CI) 0.78 to 1.01; 5 trials, 1394 children; high-certainty evidence), or at four to seven days (RR 0.76, 95% CI 0.50 to 1.14; 7 trials, 1264 children), but result in almost a third fewer children having pain at two to three days (RR 0.71, 95% CI 0.58 to 0.88; number needed to treat for an additional beneficial outcome (NNTB) 20; 7 trials, 2320 children; high-certainty evidence), and likely result in two-thirds fewer having pain at 10 to 12 days (RR 0.33, 95% CI 0.17 to 0.66; NNTB 7; 1 trial, 278 children; moderate-certainty evidence). Antibiotics increase the risk of adverse events such as vomiting, diarrhoea or rash (RR 1.38, 95% CI 1.16 to 1.63; number needed to treat for an additional harmful outcome (NNTH) 14; 8 trials, 2107 children; high-certainty evidence). Antibiotics reduce the risk of children having abnormal tympanometry findings at two to four weeks (RR 0.83, 95% CI 0.72 to 0.96; NNTB 11; 7 trials, 2138 children), slightly reduce the risk of experiencing tympanic membrane perforations (RR 0.43, 95% CI 0.21 to 0.89; NNTB 33; 5 trials, 1075 children) and halve the risk of contralateral otitis episodes (RR 0.49, 95% CI 0.25 to 0.95; NNTB 11; 4 trials, 906 children). However, antibiotics do not reduce the risk of abnormal tympanometry findings at six to eight weeks (RR 0.89, 95% CI 0.70 to 1.13; 3 trials, 953 children) and at three months (RR 0.94, 95% CI 0.66 to 1.34; 3 trials, 809 children) or late AOM recurrences (RR 0.94, 95% CI 0.79 to 1.11; 6 trials, 2200 children). Severe complications were rare, and the evidence suggests that serious complications do not differ between children treated with either antibiotics or placebo. Immediate antibiotics versus expectant observation We included six trials (1556 children) from high-income countries. The evidence suggests that immediate antibiotics may result in a reduction of pain at two to three days (RR 0.53, 95% CI 0.35 to 0.79; NNTB 8; 1 trial, 396 children; low-certainty evidence), but probably do not reduce the risk of pain at three to seven days (RR 0.75, 95% CI 0.50 to 1.12; 4 trials, 959 children; moderate-certainty evidence), and may not reduce the risk of pain at 11 to 14 days (RR 0.91, 95% CI 0.75 to 1.10; 1 trial, 247 children; low-certainty evidence). Immediate antibiotics increase the risk of vomiting, diarrhoea or rash (RR 1.87, 95% CI 1.39 to 2.51; NNTH 10; 3 trials, 946 children; high-certainty evidence). Immediate antibiotics probably do not reduce the proportion of children with abnormal tympanometry findings at four weeks and evidence suggests that immediate antibiotics may not reduce the risk of tympanic membrane perforation and AOM recurrences. No serious complications occurred in either group. AUTHORS' CONCLUSIONS This review reveals that antibiotics probably have no effect on pain at 24 hours, 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 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. For most children with mild disease in high-income countries, an expectant observational approach seems justified. Therefore, clinical management should emphasise advice about adequate analgesia and the limited role for antibiotics.

Abstract
OBJECTIVES To determine if children with cystic fibrosis (CF) who are otitis media prone and treated with tympanostomy tube placement (TTP) follow the natural course of non-CF children regarding the incidence of tympanostomy tube otorrhea (TTO) (21-34%). METHODS All CF patients seen at a large tertiary pediatric hospital were retrospectively reviewed from 2010 to 2019. A total of 483 patients were identified and seventeen met the inclusion criteria and were included in the analysis. Data collected included demographics, CF diagnosis history including date of diagnosis and genotype, TTP notes, and otorrhea found in otolaryngology clinic and pediatrician clinic notes for up to 18 months post-TTP. RESULTS CF was diagnosed at a median age of 13 days (0 days to 6 years). In terms of surgical frequency, 14/17 (82.4%) patients had one TTP, 2/17 (11.8%) had two TTPs, and 1/17 (5.9%) had five TTPs. The median (range) age at first TTP was 2 years (3 months to 13 years). After the first TTP, TTO occurred in 5 (29.4%) patients at 3 months, 6 (35.3%) at 6 and 9 months, and 7 (41.2%) at 12 and 18 months at median (range) = 1 (0-5) otolaryngology appointments and median (range) = 0 (0-8) pediatrician appointments. CONCLUSION To our knowledge this is the first study to report that CF children are more likely to be severely affected with recurrent acute otitis media (RAOM), to require TTP, and to exhibit a natural history of TTO commensurate with the non-CF population.

Abstract
CONTEXT Children with tympanostomy tubes often develop ear discharge. OBJECTIVE Synthesize evidence about the need for water precautions (ear plugs or swimming avoidance) and effectiveness of topical versus oral antibiotic treatment of otorrhea in children with tympanostomy tubes. DATA SOURCES Searches in Medline, the Cochrane Central Trials Registry and Cochrane Database of Systematic Reviews, Excerpta Medica Database, and the Cumulative Index to Nursing and Allied Health Literature. STUDY SELECTION Abstracts and full-text articles independently screened by 2 investigators. DATA EXTRACTION 25 articles were included. RESULTS One randomized controlled trial (RCT) in children assigned to use ear plugs versus no precautions reported an odds ratio (OR) of 0.68 (95% confidence interval, 0.37-1.25) for >1 episode of otorrhea. Another RCT reported an OR of 0.71 (95% confidence interval, 0.29-1.76) for nonswimmers versus swimmers. Network meta-analyses suggest that, relative to oral antibiotics, topical antibiotic-glucocorticoid drops were more effective: OR 5.3 (95% credible interval, 1.2-27). The OR for antibiotic-only drops was 3.3 (95% credible interval, 0.74-16). Overall, the topical antibiotic-glucocorticoid and antibiotic-only preparations have the highest probabilities, 0.77 and 0.22 respectively, of being the most effective therapies. LIMITATIONS Sparse randomized evidence (2 RCTs) and high risk of bias for nonrandomized comparative studies evaluating water precautions. Otorrhea treatments include non-US Food and Drug Administration approved, off-label, and potentially ototoxic antibiotics. CONCLUSIONS No compelling evidence of a need for water precautions exists. Cure rates are higher for topical drops than oral antibiotics.

Abstract
BACKGROUND Ear discharge (otorrhoea) is common in children with grommets (ventilation/tympanostomy tubes); the proportion of children developing discharge ranges from 25% to 75%. The most common treatment strategies include oral broad-spectrum antibiotics, antibiotic eardrops or those containing a combination of antibiotic(s) and a corticosteroid, and initial observation. Important drivers for one strategy over the other are concerns over the side effects of oral antibiotics and the potential ototoxicity of antibiotic eardrops. OBJECTIVES To assess the benefits and harms of current treatment strategies for children with ear discharge occurring at least two weeks following grommet (ventilation tube) insertion. SEARCH METHODS The Cochrane ENT Information Specialist searched the ENT Trials Register, CENTRAL (2016, Issue 5), multiple databases and additional sources for published and unpublished trials (search date 23 June 2016). SELECTION CRITERIA Randomised controlled trials comparing at least two of the following: oral antibiotics, oral corticosteroids, antibiotic eardrops (with or without corticosteroid), corticosteroid eardrops, microsuction cleaning of the ear canal, saline rinsing of the ear canal, placebo or no treatment. The main comparison of interest was antibiotic eardrops (with or without corticosteroid) versus oral antibiotics. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. Primary outcomes were: proportion of children with resolution of ear discharge at short-term follow-up (less than two weeks), adverse events and serious complications. Secondary outcomes were: proportion of children with resolution of ear discharge at intermediate- (two to four weeks) and long-term (four to 12 weeks) follow-up, proportion of children with resolution of ear pain and fever at short-term follow-up, duration of ear discharge, proportion of children with chronic ear discharge, ear discharge recurrences, tube blockage, tube extrusion, health-related quality of life and hearing. We used GRADE to assess the quality of the evidence for each outcome; this is indicated in italics. MAIN RESULTS We included nine studies, evaluating a range of treatments, with 2132 children who developed acute ear discharge beyond the immediate postoperative period. We judged the risk of bias to be low to moderate in most studies. Antibiotic eardrops (with or without corticosteroid) versus oral antibioticsAntibiotic eardrops with or without corticosteroid were more effective than oral antibiotics in terms of:- resolution of discharge at one week (one study, 42 children, ciprofloxacin eardrops versus amoxicillin: 77% versus 30%; risk ratio (RR) 2.58, 95% confidence interval (CI) 1.27 to 5.22; moderate-quality evidence);- resolution of discharge at two weeks (one study, 153 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 95% versus 56%; RR 1.70, 95% CI 1.38 to 2.08; moderate-quality evidence);- duration of discharge (two studies, 233 children, ciprofloxacin eardrops versus amoxicillin: median 4 days versus 7 days and bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 4 days versus 5 days; moderate-quality evidence);- ear discharge recurrences (one study, 148 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: 0 versus 1 episode at six months; low-quality evidence); and- disease-specific quality of life (one study, 153 children, bacitracin-colistin-hydrocortisone eardrops versus amoxicillin-clavulanate: difference in change in median Otitis Media-6 total score (range 6 to 42) at two weeks: -2; low-quality evidence).We found no evidence that antibiotic eardrops were more effective in terms of the proportion of children developing chronic ear discharge or tube blockage, generic quality of life or hearing.Adverse events occurred at similar rates in children treated with antibiotic eardrops and those treated with oral antibiotics, while no serious complications occurred in either of the groups. Other comparisons(a) Antibiotic eardrops with or without corticosteroid were more effective thancorticosteroid eardrops in terms of:- duration of ear discharge (one study, 331 children, ciprofloxacin versus ciprofloxacin-fluocinolone acetonide versus fluocinolone acetonide eardrops: median 5 days versus 7 days versus 22 days; moderate-quality evidence).(b) Antibiotic eardrops were more effective than saline rinsing of the ear canal in terms of:- resolution of ear discharge at one week (one study, 48 children, ciprofloxacin eardrops versus saline rinsing: 77% versus 46%; RR 1.67, 95% CI 1.04 to 2.69; moderate-quality evidence);but not in terms of tube blockage. Since the lower limit of the 95% CI for the effect size for resolution of ear discharge at one week approaches unity, a trivial or clinically irrelevant difference cannot be excluded.(c) Eardrops containing two antibiotics and a corticosteroid (bacitracin-colistin-hydrocortisone) were more effective than no treatment in terms of:- resolution of discharge at two weeks (one study; 151 children: 95% versus 45%; RR 2.09, 95% CI 1.62 to 2.69; moderate-quality evidence);- duration of discharge (one study; 147 children, median 4 days versus 12 days; moderate-quality evidence);- chronic discharge (one study; 147 children; RR 0.08, 95% CI 0.01 to 0.62; low-quality evidence); and- disease-specific quality of life (one study, 153 children, difference in change in median Otitis Media-6 total score (range 6 to 42) between groups at two weeks: -1.5; low-quality evidence).We found no evidence that antibiotic eardrops were more effective in terms of ear discharge recurrences or generic quality of life.(d) Eardrops containing a combination of an antibiotic and a corticosteroid were more effective than eardrops containing antibiotics (low-quality evidence) in terms of:- resolution of ear discharge at short-term follow-up (two studies, 590 children: 35% versus 20%; RR 1.76, 95% CI 1.33 to 2.31); and- duration of discharge (three studies, 813 children);but not in terms of resolution of discharge at intermediate-term follow-up or proportion of children with tube blockage. However, there is a substantial risk of publication bias, therefore these findings should be interpreted with caution. AUTHORS' CONCLUSIONS We found moderate to low-quality evidence that antibiotic eardrops (with or without corticosteroid) are more effective than oral antibiotics, corticosteroid eardrops and no treatment in children with ear discharge occurring at least two weeks following grommet insertion. There is some limited, inconclusive evidence that antibiotic eardrops are more effective than saline rinsing. There is uncertainty whether antibiotic-corticosteroid eardrops are more effective than eardrops containing antibiotics only.

Abstract
BACKGROUND The insertion of grommets (also known as ventilation or tympanostomy tubes) is one of the most common surgical procedures performed on children. Postoperative otorrhoea (discharge) is the most common complication with a reported incidence ranging from 10% to 50%. In the UK, many ENT surgeons treat with topical antibiotics/steroid combinations, but general practitioners, mainly through fears of ototoxicity, are unlikely to prescribe these and choose systemic broad-spectrum antibiotics. OBJECTIVES 1. To identify the most effective non-surgical management of discharge from ears with grommets in place.2. To identify the risks of non-surgical management for this condition (e.g. ototoxicity), and to set benefits of treatment against these risks. SEARCH METHODS We searched the Cochrane Ear, Nose and Throat Disorders Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2005), MEDLINE (1966 to 2005) and EMBASE (1974 to 2005). We also searched the CINAHL, AMED, LILACS, ISI WEB OF KNOWLEDGE, ISI PROCEEDINGS, mRCT, NNR, ZETOC, KOREAMED, CSA, MEDCARIB, INDMED and SAMED databases. The date of the last search was February 2005. SELECTION CRITERIA Randomised controlled trials of adults or children, with any type of grommet and an ear with discharge were included. The trials compared treatment with placebo or one treatment with another. The primary outcome measure was the duration of the discharge. DATA COLLECTION AND ANALYSIS The trials were selected independently according to the above criteria by the four reviewers. Differences in opinion over the inclusion of studies were resolved by discussion. The studies were graded using the CASP critical appraisal tool. Analyses were based on the presence of discharge seven days from the onset of treatment. MAIN RESULTS There was very little good quality evidence. Four studies were included, all of them investigating different interventions and therefore a meta-analysis was not possible.Only one study demonstrated a significant difference. Oral amoxicillin clavulanate was compared to placebo in 79 patients. The odds of having a discharge persisting eight days after starting treatment was 0.19 (95% CI 0.07 to 0.49) . The number needed to treat to achieve that benefit is 2.5. Participants in both arms of this study also received daily aural toilet. The results will therefore not be applicable to most settings including primary care. No significant benefit was shown in the two studies investigating steroids (oral prednisolone with oral amoxicillin clavulanate and topical dexamethasone with topical ciprofloxacin ear drops), or the one study comparing an antibiotic-steroid combination (Otosporin®) drops versus spray (Otomize®) (although more patients preferred the spray form). AUTHORS' CONCLUSIONS The authors of this review have been unable to identify the most effective intervention or to assess the associated risks. Research is urgently needed into the effectiveness of oral versus topical antibiotics in this group of patients. Clinicians considering antibiotic treatment need to balance any potential benefit against the risks of side effects and antibiotic resistance.

Abstract
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.

Abstract
BACKGROUND When prescribing antibiotics for common indications, clinicians need information about both harms and benefits, information that is currently available only from observational studies. We quantified the common harms of the most frequently prescribed antibiotic, amoxicillin, from randomized placebo-controlled trials. METHODS For this systematic review, we searched MEDLINE, Embase and the Cochrane Central Register of Controlled Trials, without language restriction, for any randomized, participant-blinded, placebo-controlled trials of amoxicillin or amoxicillin-clavulanic acid for any indication, in any setting. Our main outcome was any reported adverse event. RESULTS Of 730 studies identified, we included 45 trials: 27 involving amoxicillin, 17 involving amoxicillin-clavulanic acid and 1 involving both. The indications for antibiotic therapy were variable. The risk of bias was low, although only 25 trials provided data suitable for assessment of harms, which suggested under-reporting. Diarrhea was attributed to amoxicillin only in the form of amoxicillin-clavulanic acid (Peto odds ratio [OR] 3.30, 95% confidence interval [CI] 2.23-4.87). The OR for candidiasis (3 trials) was significantly higher (OR 7.77, 95% CI 2.23-27.11). Rashes, nausea, itching, vomiting and abnormal results on liver function tests were not significantly increased. The results were not altered by sensitivity analyses, nor did funnel plots suggest publication bias. The number of courses of antibiotics needed to harm was 10 (95% CI 6-17) for diarrhea with amoxicillin-clavulanic acid and 27 (95% CI 24-42) for candidiasis with amoxicillin (with or without clavulanic acid). INTERPRETATION Diarrhea was caused by use of amoxicillin-clavulanic acid, and candidiasis was caused by both amoxicillin and amoxicillin-clavulanic acid. Harms were poorly reported in most trials, and their true incidence may have been higher than reported. Nevertheless, these rates of common harms associated with amoxicillin therapy may inform decisions by helping clinicians to balance harms against benefits.

Abstract
BACKGROUND Recent guidance for the management of acute otorrhea in children with tympanostomy tubes is based on limited evidence from trials comparing oral antibiotic agents with topical antibiotics. METHODS In this open-label, pragmatic trial, we randomly assigned 230 children, 1 to 10 years of age, who had acute tympanostomy-tube otorrhea to receive hydrocortisone-bacitracin-colistin eardrops (76 children) or oral amoxicillin-clavulanate suspension (77) or to undergo initial observation (77). The primary outcome was the presence of otorrhea, as assessed otoscopically, 2 weeks after study-group assignment. Secondary outcomes were the duration of the initial otorrhea episode, the total number of days of otorrhea and the number of otorrhea recurrences during 6 months of follow-up, quality of life, complications, and treatment-related adverse events. RESULTS Antibiotic-glucocorticoid eardrops were superior to oral antibiotics and initial observation for all outcomes. At 2 weeks, 5% of children treated with antibiotic-glucocorticoid eardrops had otorrhea, as compared with 44% of those treated with oral antibiotics (risk difference, -39 percentage points; 95% confidence interval [CI], -51 to -26) and 55% of those treated with initial observation (risk difference, -49 percentage points; 95% CI, -62 to -37). The median duration of the initial episode of otorrhea was 4 days for children treated with antibiotic-glucocorticoid eardrops versus 5 days for those treated with oral antibiotics (P<0.001) and 12 days for those who were assigned to initial observation (P<0.001). Treatment-related adverse events were mild, and no complications of otitis media, including local cellulitis, perichondritis, mastoiditis, and intracranial complications, were reported at 2 weeks. CONCLUSIONS Antibiotic-glucocorticoid eardrops were more effective than oral antibiotics and initial observation in children with tympanostomy tubes who had uncomplicated acute otorrhea.

Abstract
BACKGROUND Grommets are frequently inserted in children's ears for acute otitis media and otitis media with effusion. A common complication is postoperative ear discharge (otorrhoea). A wide range of treatments are used to prevent the discharge, but there is no consensus on whether or not intervention is necessary nor which is the most effective intervention. OBJECTIVES To assess the effectiveness of prophylactic interventions, both topical and systemic, in reducing the incidence of otorrhoea following the surgical insertion of grommets in children. SEARCH METHODS We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ICTRP and additional sources for published and unpublished trials. The date of the search was 3 July 2012. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared the efficacy of prophylactic interventions against placebo/control and/or with other prophylactic interventions for postoperative otorrhoea in children. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility and risk of bias, and extracted data. The outcome data were dichotomous for all the included trials. We calculated individual and pooled risk ratios (RR) using the Mantel-Haenszel fixed-effect method. We also calculated the numbers needed to treat to benefit (NNTB). MAIN RESULTS We found 15 eligible RCTs (2476 children, aged from four months to 17 years). We graded seven RCTs as being at a low risk of bias (n = 926 children) and for an eighth RCT we also graded two of the arms as being at a low risk of bias. We graded the other seven trials as being at a high risk of bias.For a single application at surgery, there was evidence from two low risk of bias trials that at two weeks postoperatively the risk of otorrhoea was reduced by multiple saline washouts (from 30% to 16%; RR 0.52, 95% confidence interval (CI) 0.27 to 1.00; NNTB 7; one RCT; 140 children) and antibiotic/steroid ear drops (from 9% to 1%; RR 0.13, 95% CI 0.03 to 0.57; NNTB 13; one RCT; 322 ears). A meta-analysis of two low risk of bias trials (222 ears) failed to find an effect of a single application of antibiotic/steroid ear drops at four to six weeks postoperatively.For a prolonged application of an intervention, there was evidence from four low risk of bias trials that the risk of otorrhoea was reduced two weeks postoperatively by antibiotic ear drops (from 15% to 8%; RR 0.54, 95% CI 0.30 to 0.97; NNTB 15; one RCT; 372 children), antibiotic/steroid ear drops (from 39% to 5%; RR 0.13, 95% CI 0.05 to 0.31; NNTB 3; one RCT; 200 children), aminoglycoside/steroid ear drops (from 15% to 5%; RR 0.37, 95% CI 0.18 to 0.74; NNTB 11; one RCT; 356 children) or oral antibacterial agents/steroids (from 39% to 5%; RR 0.13, 95% CI 0.03 to 0.51; NNTB 3; one RCT; 77 children).Only one trial assessed the secondary outcome of ototoxicity, but no effect was found. There were no trials that assessed quality of life. AUTHORS' CONCLUSIONS Our review found that each of the following were effective at reducing the rate of otorrhoea up to two weeks following surgery: (1) multiple saline washouts at surgery, (2) a single application of topical antibiotic/steroid drops at surgery, (3) a prolonged application of topical drops (namely antibiotic ear drops, antibiotic/steroid eardrops or aminoglycoside/steroid ear drops) and (4) a prolonged application of oral antibacterial agents/steroids. However, the rate of otorrhoea between RCTs varied greatly and the higher the rates of otorrhoea within a RCT, the smaller the NNTB for therapy.We conclude that if a surgeon has a high rate of postoperative otorrhoea in children then either saline irrigation or antibiotic ear drops at the time of surgery would significantly reduce that rate. If topical drops are chosen, it is suggested that to reduce the cost and potential for ototoxic damage this be a single application at the time of surgery and not prolonged thereafter.

Abstract
OBJECTIVE Bilateral acute otitis media (AOM) is considered more severe than unilateral AOM, and several guidelines recommend more active treatment and/or follow-up of bilateral AOM. We studied whether bilateral AOM is a clinically more severe illness than unilateral AOM by comparing symptoms and otoscopic signs between bilateral and unilateral AOM. METHODS Two hundred thirty-two children aged 6 to 35 months diagnosed with AOM were eligible. We surveyed the symptoms with a structured questionnaire and recorded the otoscopic signs systematically. RESULTS Ninety-eight children had bilateral and 134 children unilateral AOM. Children with bilateral AOM were more often <24 months than children with unilateral AOM (87% vs 75%; P = .032). Fever (≥38°C) occurred in 54% and 36% (P = .006) and severe conjunctivitis in 16% and 44% (P = .047) of children with bilateral and unilateral AOM, respectively. In 15 other symptoms, we found no overall differences even when adjusted with age. We observed the following severe otoscopic signs in the bilateral and unilateral AOM group, respectively: moderate/marked bulging of tympanic membrane (63% and 40%; P = .001), purulent effusion (89% and 71%; P = .001), bulla formation (11% and 10%; P = .707), and hemorrhagic redness of tympanic membrane (7% and 10%; P = .386). CONCLUSIONS Bilateral AOM seems to be a clinically only slightly more severe illness than unilateral AOM. Therefore, when assessing AOM severity, bilaterality should not be used as a determining criterion; instead, the child's symptomatic condition together with otoscopic signs should also be taken into consideration.

Abstract
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. OBJECTIVES To assess the effects of antibiotics for children with AOM. SEARCH METHODS We searched CENTRAL (2012, Issue 10), MEDLINE (1966 to October week 4, 2012), OLDMEDLINE (1958 to 1965), EMBASE (January 1990 to November 2012), Current Contents (1966 to November 2012), CINAHL (2008 to November 2012) and LILACS (2008 to November 2012). 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, 12 RCTs (3317 children and 3854 AOM episodes) from high-income countries were eligible. However, one trial did not report patient-relevant outcomes, leaving 11 trials with generally low risk of bias. 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) and fewer had pain at four to seven days (RR 0.79; 95% CI 0.66 to 0.95; NNTB 20). When compared with placebo, antibiotics did not alter the number of abnormal tympanometry findings at either four to six weeks (RR 0.92; 95% CI 0.83 to 1.01) or at three months (RR 0.97; 95% CI 0.76 to 1.24), or the number of AOM recurrences (RR 0.93; 95% CI 0.78 to 1.10). However, antibiotic treatment did lead to a statistically significant reduction of tympanic membrane perforations (RR 0.37; 95% CI 0.18 to 0.76; NNTB 33) and halved contralateral AOM episodes (RR 0.49; 95% CI 0.25 to 0.95; NNTB 11) as 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 1.34; 95% CI 1.16 to 1.55; 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 with bilateral AOM, or with both AOM and otorrhoea.For the review of immediate antibiotics against expectant observation, five trials (1149 children) were eligible. 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 on pain at days three to seven. No difference in pain was detectable at three to seven days (RR 0.75; 95% CI 0.50 to 1.12). No serious complications occurred in either the antibiotic group or the expectant observation group. Additionally, no difference in tympanic membrane perforations and AOM recurrence was observed. Immediate antibiotic prescribing was associated with a substantial increased risk of vomiting, diarrhoea or rash as compared with expectant observation (RR 1.71; 95% CI 1.24 to 2.36). AUTHORS' CONCLUSIONS Antibiotic treatment led to a statistically significant reduction of children with AOM experiencing pain at two to seven days compared with placebo but since most children (82%) settle spontaneously, about 20 children must be treated to prevent one suffering from ear pain at two to seven days. Additionally, antibiotic treatment led to a statistically significant reduction of tympanic membrane perforations (NNTB 33) and contralateral AOM episodes (NNTB 11). These benefits 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 had been withheld. Antibiotics appear to be 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, an expectant observational approach seems justified. We have no trials in populations with higher risks of complications.

Abstract
OBJECTIVE The aim of this review was to study the effectiveness of ventilation tube (VT) treatment in children with secretory otitis media (SOM), assessed by improved hearing, normalized language and quality of life (QoL), and recurrent acute otitis media (rAOM), assessed by number of episodes of AOM and QoL. Data Sources. Cochrane Library, PubMed, and Embase databases were searched for randomized and nonrandomized controlled trials and cohort studies in English, Scandinavian, German, and French languages between 1966 and April 2007. Additional literature was retrieved from reference lists in the articles. REVIEW METHODS A total of 493 abstracts were evaluated independently by 2 members of the project group, 247 full-text versions were assessed for inclusion criteria and quality using structured evaluation forms, and 63 articles were included in the review. RESULTS AND CONCLUSIONS This review shows that there is strong scientific evidence (grade 1) that VT treatment of SOM improves hearing for at least 9 months and that QoL is improved for up to 9 months (grade 2 scientific evidence). There was insufficient evidence to support an effect of VT treatment for rAOM. There was also insufficient evidence to determine whether the design or material of the VT or the procedure used for insertion had any influence on the effect; however, there was some evidence (grade 3) that aspiration of secretion at insertion does not prolong VT treatment. Further research is needed to address these issues.

Abstract
BACKGROUND The efficacy of antimicrobial treatment in children with acute otitis media remains controversial. METHODS In this randomized, double-blind trial, children 6 to 35 months of age with acute otitis media, diagnosed with the use of strict criteria, received amoxicillin-clavulanate (161 children) or placebo (158 children) for 7 days. The primary outcome was the time to treatment failure from the first dose until the end-of-treatment visit on day 8. The definition of treatment failure was based on the overall condition of the child (including adverse events) and otoscopic signs of acute otitis media. RESULTS Treatment failure occurred in 18.6% of the children who received amoxicillin-clavulanate, as compared with 44.9% of the children who received placebo (P<0.001). The difference between the groups was already apparent at the first scheduled visit (day 3), at which time 13.7% of the children who received amoxicillin-clavulanate, as compared with 25.3% of those who received placebo, had treatment failure. Overall, amoxicillin-clavulanate reduced the progression to treatment failure by 62% (hazard ratio, 0.38; 95% confidence interval [CI], 0.25 to 0.59; P<0.001) and the need for rescue treatment by 81% (6.8% vs. 33.5%; hazard ratio, 0.19; 95% CI, 0.10 to 0.36; P<0.001). Analgesic or antipyretic agents were given to 84.2% and 85.9% of the children in the amoxicillin-clavulanate and placebo groups, respectively. Adverse events were significantly more common in the amoxicillin-clavulanate group than in the placebo group. A total of 47.8% of the children in the amoxicillin-clavulanate group had diarrhea, as compared with 26.6% in the placebo group (P<0.001); 8.7% and 3.2% of the children in the respective groups had eczema (P=0.04). CONCLUSIONS Children with acute otitis media benefit from antimicrobial treatment as compared with placebo, although they have more side effects. Future studies should identify patients who may derive the greatest benefit, in order to minimize unnecessary antimicrobial treatment and the development of bacterial resistance.

Abstract
Aimed to prevent Streptococcus pneumoniae biofilm infections, we studied the adherence of nine pneumococcal strains to polystyrene plates and on epithelial cells and the antiadhesive effect of albumin and xylitol. The adherence was variable among strains, but there was a good correlation between their adherent ability and binding to abiotic material and cells. Strains of serotypes 6B and 23F were the most adherent organisms, whereas serotype 3 strains were the least adherent. Human serum albumin (HSA) enhanced bacterial growth at low concentrations (0.5-2.5%) but inhibited it at 10%. Xylitol inhibited bacterial growth of all strains at concentrations ranging from 5 to 15%. Exposure to 0.5-5% HSA in solubilized form and to 5% HSA precoating of plates diminished adherence to polystyrene >80% for all strains, except for serotype 3 strains. Contrarily, 0.5 and 5% xylitol did not diminish significantly pneumococcal adherence to polystyrene plates or on epithelial cells. Our results suggest that 1) the potential application of HSA coatings on medical devices to inhibit pneumococcal adherence and 2) the possible beneficial effect of xylitol in preventing some pneumococcal infections could be because of its antimicrobial activity rather than to an antiadhesive effect.

Abstract
OBJECTIVE To establish if otorrhea associated to tympanostomy tubes in infants suffering from recurrent acute otitis media is similar to acute otitis media, and if topical treatment alone is sufficient or if addition of systemic antibiotics is required. METHODS Children under 3 years of age with tympanostomy tubes due to recurrent acute otitis media were recruited to the study. The study design was open label randomized and prospective. Fifty patients were allocated to either of two treatment groups and were monitored for 6 months. Group I received only topical treatment (commercially available ear drops and saline solution) in case of otorrhea. Group II was treated with topical treatment together with systemic antibiotics. All episodes of acute otorrhea were registered. Main outcome measure was duration of otorrhea in days. Bacterial samples from the ear discharge were taken. RESULTS Forty-one episodes were treated according to protocol. The bacteriological testing mainly showed bacteria typical of acute otitis media. A majority of episodes were cured within 7 days in both groups, and statistical analysis showed no significant difference between the treatment groups in duration of otorrhea. In Group I systemic antibiotics were added in one-third (7/21) of the episodes due to signs of affected general condition such as high fever and severe earache. CONCLUSIONS The otorrhea episodes in the study were similar to acute otitis media based on the bacteriological results. Topical treatment alone might be used as first treatment of choice. Although systemic antibiotics were added in several cases in the topical treatment group, the findings of the study do not support use of systemic antibiotics for tube associated otorrhea in RAOM children in general.

Abstract
BACKGROUND The objective of this study was to determine the association between early bacteriologic failure and clinical failure in acute otitis media (AOM). METHODS Children with AOM aged 3-35 months enrolled in studies documenting both bacteriologic outcomes by tympanocentesis on day 4-6 and clinical outcomes on day 11-16 (immediate posttreatment visit) constituted our study group. Bacteriologic outcomes were studied for children with AOM caused by Streptococcus pneumoniae, nontypeable Haemophilus influenzae or both. The relative risk (RR) for clinical failure of children with bacteriologic failure compared with children with bacteriologic eradication was the main outcome measure. RESULTS Nine hundred seven episodes were analyzed. Clinical failure occurred in 7.3% of 660 patients with bacterial eradication versus 32.8% of 247 patients with bacteriologic failures. The overall RR (95% confidence interval) for clinical failure was 4.41 (95% CI: 3.19-6.11), with little variation between pathogens. After correction for age, gender, ethnic origin, previous otitis history, and previous antibiotic treatment, the rate was 6.52 (95% CI: 4.26-9.99). Across clinical studies with 8 antibiotic drug regimens for AOM, the rate of clinical failure correlated with bacteriologic failure (r = 0.8967; P = 0.003). CONCLUSIONS In young children with culture-positive AOM, failure to eradicate the pathogen from middle ear fluid within the first few days of treatment leads to a significant risk for clinical failure.

Abstract
BACKGROUND Dynamics of bacteria during acute otitis media (AOM) has not been thoroughly studied because it requires repeated tympanocentesis. AOM with tympanostomy tube otorrhea provides a unique opportunity to study the appearance and disappearance of pathogens during the course of the disease without stressing the child. METHODS Middle ear fluid (MEF) samples were taken before treatment (amoxicillin clavulanate or placebo) and then daily during follow-up from 75 children having AOM with otorrhea through a tympanostomy tube. Bacteria were identified by culture, and typical AOM pathogens also by polymerase chain reaction. RESULTS Bacteria were initially shown in 67 (89%) children. New bacteria appeared in MEF more often in placebo than in amoxicillin clavulanate recipients [9 of 38 (24%) versus 2 of 37 (5%); P = 0.032]. During the follow-up, new occurrences of Moraxella catarrhalis were detected in MEF more frequently than those of Streptococcus pneumoniae or Haemophilus influenzae. Of the 28 patients with bilateral otorrhea, 11 (39%) had disparate bacteria at study entry and/or during the follow-up. CONCLUSIONS Changes in bacterial findings during the course of AOM are common in patients not receiving treatment, and even possible despite adequate treatment. In bilateral otorrhea, disparate bacterial findings are common.

Abstract
OBJECTIVE The goal was to determine the predictors of a prolonged course for children with acute otitis media. METHODS A meta-analysis of data with the observation groups of 6 randomized, controlled trials was performed. Participants were 824 children, 6 months to 12 years of age, with acute otitis media. The primary outcome was a prolonged course of acute otitis media, which was defined as fever and/or pain at 3 to 7 days. RESULTS Of the 824 included children, 303 had pain and/or fever at 3 to 7 days. Independent predictors of a prolonged course were age of < 2 years and bilateral acute otitis media. The absolute risk of pain and/or fever at 3 to 7 days for children < 2 years of age with bilateral acute otitis media (20% of all children) was 55%, and that for children > or = 2 years of age with unilateral acute otitis media (47% of all children) was 25%. CONCLUSIONS The risk of a prolonged course was 2 times higher for children < 2 years of age with bilateral acute otitis media than for children > or = 2 years of age with unilateral acute otitis media. Clinicians can use these features (ie, age of < 2 years and bilateral acute otitis media) to inform parents more explicitly about the expected course of their child's otitis media and to explain which features should prompt parents to contact their clinician for reexamination of the child.

Abstract
Background. Bacteria are found in 50%–90% of cases of acute otitis media (AOM) with or without otorrhea, and viruses are found in 20%–49% of cases. However, for at least 15% of patients with AOM, the microbiological etiology is never determined. Our aim was to specify the full etiology of acute middle ear infection by using modern microbiological methods concomitantly for bacterial and viral detection. Methods. The subjects were 79 young children having AOM with new onset (<48 h) of otorrhea through a tympanostomy tube. Middle ear fluid samples were suctioned from the middle ear through the tympanostomy tube. Bacteria were sought by culture and polymerase chain reaction; viruses were analyzed by culture, antigen detection, and polymerase chain reaction. Results. At least 1 respiratory tract pathogen was noted in 76 children (96%). Bacteria were found in 73 cases (92%), and viruses were found in 55 (70%). In 52 patients (66%), both bacteria and viruses were found. Bacteria typical of AOM were detected in 86% of patients. Picornaviruses accounted for 60% of all viral findings. Conclusions. In the great majority of children, AOM is a coinfection with bacteria and viruses. The patent tympanostomy tube does not change the spectrum of causative agents in AOM. A microbiological etiology can be established in practically all cases.

Abstract
BACKGROUND Individual trials to test effectiveness of antibiotics in children with acute otitis media have been too small for valid subgroup analyses. We aimed to identify subgroups of children who would and would not benefit more than others from treatment with antibiotics. METHODS We did a meta-analysis of data from six randomised trials of the effects of antibiotics in children with acute otitis media. Individual patient data from 1643 children aged from 6 months to 12 years were validated and re-analysed. We defined the primary outcome as an extended course of acute otitis media, consisting of pain, fever, or both at 3-7 days. FINDINGS Significant effect modifications were noted for otorrhoea, and for age and bilateral acute otitis media. In children younger than 2 years of age with bilateral acute otitis media, 55% of controls and 30% on antibiotics still had pain, fever, or both at 3-7 days, with a rate difference between these groups of -25% (95% CI -36% to -14%), resulting in a number-needed-to-treat (NNT) of four children. We identified no significant differences for age alone. In children with otorrhoea the rate difference and NNT, respectively, were -36% (-53% to -19%) and three, whereas in children without otorrhoea the equivalent values were -14% (-23% to -5%) and eight. INTERPRETATION Antibiotics seem to be most beneficial in children younger than 2 years of age with bilateral acute otitis media, and in children with both acute otitis media and otorrhoea. For most other children with mild disease an observational policy seems justified.

Abstract
Otitis media is one of the most common disorders occurring in children, and there is growing concern that bacteria are quickly becoming resistant to antimicrobials. As a result, global antibiotic treatment is no longer the standard of care and treatment of otitis media has changed dramatically in the last decade. In addition to new antimicrobials currently in development, the effects of the pneumococcal conjugate vaccine are just beginning to be understood. Furthermore, new surgical techniques are for the first time being tested as alternatives for tympanostomy tubes for recurrent acute otitis media. This review discusses current and emerging otitis media therapeutics, with particular attention to acute otitis media. Topics include antimicrobial use, antimicrobial resistance, effects of vaccination and new surgical techniques.

Abstract
BACKGROUND The insertion of grommets (also known as ventilation or tympanostomy tubes) is one of the most common surgical procedures performed on children. Postoperative otorrhoea (discharge) is the most common complication with a reported incidence ranging from 10% to 50%. In the UK, many ENT surgeons treat with topical antibiotics/steroid combinations, but general practitioners, mainly through fears of ototoxicity, are unlikely to prescribe these and choose systemic broad-spectrum antibiotics. OBJECTIVES 1. To identify the most effective non-surgical management of discharge from ears with grommets in place.2. To identify the risks of non-surgical management for this condition (e.g. ototoxicity), and to set benefits of treatment against these risks. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2005), MEDLINE (1966 to 2005) and EMBASE (1974 to 2005). We also searched the CINAHL, AMED, LILACS, ISI WEB OF KNOWLEDGE, ISI PROCEEDINGS, mRCT, NNR, ZETOC, KOREAMED, CSA, MEDCARIB, INDMED and SAMED databases. The date of the last search was February 2005. SELECTION CRITERIA Randomised controlled trials of adults or children, with any type of grommet and an ear with discharge were included. The trials compared treatment with placebo or one treatment with another. The primary outcome measure was the duration of the discharge. DATA COLLECTION AND ANALYSIS The trials were selected independently according to the above criteria by the four reviewers. Differences in opinion over the inclusion of studies were resolved by discussion. The studies were graded using the CASP critical appraisal tool. Analyses were based on the presence of discharge seven days from the onset of treatment. MAIN RESULTS There was very little good quality evidence. Four studies were included, all of them investigating different interventions and therefore a meta-analysis was not possible. Only one study demonstrated a significant difference. Oral amoxicillin clavulanate was compared to placebo in 79 patients. The odds of having a discharge persisting eight days after starting treatment was 0.19 (95% CI 0.07 to 0.49) . The number needed to treat to achieve that benefit is 2.5. Participants in both arms of this study also received daily aural toilet. The results will therefore not be applicable to most settings including primary care. No significant benefit was shown in the two studies investigating steroids (oral prednisolone with oral amoxicillin clavulanate and topical dexamethasone with topical ciprofloxacin ear drops), or the one study comparing an antibiotic-steroid combination (Otosporin(R)) drops versus spray (Otomize(R)) (although more patients preferred the spray form). AUTHORS' CONCLUSIONS The authors of this review have been unable to identify the most effective intervention or to assess the associated risks. Research is urgently needed into the effectiveness of oral versus topical antibiotics in this group of patients. Clinicians considering antibiotic treatment need to balance any potential benefit against the risks of side effects and antibiotic resistance.

Abstract
BACKGROUND Disappearance of middle ear effusion is one of the most important outcomes in the treatment of acute otitis media (AOM). AIM To evaluate the duration of effusion in AOM treated by antimicrobials and to find factors influencing it. METHODS Parents of 90 children with AOM monitored daily the disappearance of effusion with tympanometry. The children were randomly allocated to be treated with either oral amoxicillin or cefuroxime-axetil for 10 d. Daily monitoring lasted for 14 d or until the tympanogram was normal (curve A or C) in both ears. Pneumatic otoscopy was carried out every 2 wk. RESULTS Normal tympanograms were obtained after a median time of 7.5 d (range 1-58 d) among 75 successfully monitored patients. In two-thirds (69%) of them, effusion resolved in 14 d. The median duration of effusion did not differ significantly between the two treatment groups (8 vs 7 days, p=0.7). The children who had unilateral AOM cured more rapidly than those with bilateral AOM (5 vs 19 d, p<0.001). In logistic regression analysis adjusted for age, bilaterality explained treatment failure at 2 wk with an odds ratio of 28.1 (95% CI 4.6-169.5, p<0.001). CONCLUSION The choice of antimicrobials did not influence the duration of middle ear effusion, which was much shorter than had been thought previously. Children with unilateral AOM were cured much more quickly than those with bilateral AOM.

Abstract
OBJECTIVE The objective was to determine the types of organisms which cause acute otitis media with a tympanostomy tube and to ascertain their frequency distribution. STUDY DESIGN AND SETTING Prospective, randomized, multi-institutional clinical trials. Both private and academic sites were included. RESULTS 1309 isolates were recovered from 956 draining ears. Streptococcus pneumonia was recovered from 17%, Staphylococcus aureus from 13%, H flu from 18% and Pseudomonas aeruginosa from 12%. Fungal organisms were recovered from 5% of total isolates and 4% from single isolates. CONCLUSIONS AOMT is microbiologically different than AOM with an intact TM. There is no evidence that resistance develops as result of topical treatment. SIGNIFICANCE The study demonstrates that AOMT is frequently caused by organisms not susceptible to oral antibiotics approved for children, but which are sensitive to topical ear drops.

Abstract
The changing susceptibility of bacterial otopathogens is only one aspect of the evolving concepts regarding pathogenesis, immunoprophylaxis, pharmacodynamics, and sequelae of acute otitis media that mandates new insights for achieving a successful outcome. 2004 guidelines by the American Academy of Pediatrics for the treatment of acute otitis media provide one perspective that proposes a rethinking of the routine use of antimicrobial therapy with the hope of preventing further increases in bacterial resistance among otopathogens. The goals of this article are to incorporate the advances in diagnosis, treatment, prevention, and management of sequelae into strategies that optimize the outcome of acute otitis media and limit further emergence of resistant otopathogens.

Abstract
OBJECTIVE Acute post-tympanostomy otorrhea (APTO) is a common complication of tympanostomy tube placement. APTO has been related primarily to viral upper respiratory infections and external ear contamination. Elevated levels of gastric enzymes have been found in a large proportion of chronic middle ear effusions, implicating gastric reflux (GR) in its pathogenesis. Thus, our objective was to determine whether GR may be a contributing factor in the development of APTO. STUDY DESIGN AND SETTING Prospective, nonrandomized design. Otorrhea samples were collected from children with APTO. Total pepsinogen concentrations were measured with a commercial ELISA, using a pepsinogen I-specific capture antibody and horseradish peroxidase detection antibody. RESULTS Twenty-six samples from 24 patients were collected and analyzed. Eight samples demonstrated measurable pepsinogen I, but the measured concentrations, 2-17 mg/L, were below the normal serum reference ranges. CONCLUSIONS GR does not play a major role in the development of APTO in children.

There are a variety of causes of otorrhea in children. The most important factor in reaching the proper diagnosis and providing relief of the problem is aural toilet. Once adequate debridement has been performed, the diagnosis is usually clearer, and treatment with ototopicals is significantly more effective. Most cases of otorrhea are due to infection or granulation tissue and can be managed initially with appropriately selected ototopical medication, thereby avoiding the risks and side effects of systemic therapy and the need for referral to a specialist. However, otorrhea in children that is refractory to medical therapy may be due to retained tympanostomy tubes or insidious pathology such as cholesteatoma or malignancy. In such cases, prompt referral to the otolaryngologist can facilitate accurate diagnosis and successful management.

Abstract
BACKGROUND Acute otitis media is one of the most common diseases in early infancy and childhood. Antibiotic use for acute otitis media varies from 31% in the Netherlands to 98% in the USA and Australia. OBJECTIVES The objective of this review was to assess the effects of antibiotics for children with acute otitis media. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE, Index Medicus (pre 1965), Current Contents and reference lists of articles from 1958 to January 2000. The search was updated in 2003. SELECTION CRITERIA Randomised trials comparing antimicrobial drugs with placebo in children with acute otitis media. DATA COLLECTION AND ANALYSIS Three reviewers independently assessed trial quality and extracted data. MAIN RESULTS Ten trials were eligible based on design, only eight of the trials, with a total of 2,287 children, included patient-relevant outcomes. The methodological quality of the included trials was generally high. All trials were from developed countries. The trials showed no reduction in pain at 24 hours, but a 30% relative reduction (95% confidence interval 19% to 40%) in pain at two to seven days. Since approximately 80% of patients will have settled spontaneously in this time, this means an absolute reduction of 7% or that about 15 children must be treated with antibiotics to prevent one child having some pain after two days. There was no effect of antibiotics on hearing problems of acute otitis media, as measured by subsequent tympanometry. However, audiometry was done in only two studies and incompletely reported. Nor did antibiotics influence other complications or recurrence. There were few serious complications seen in these trials: only one case of mastoiditis occurred in a penicillin treated group. REVIEWER'S CONCLUSIONS Antibiotics provide a small benefit for acute otitis media in children. As most cases will resolve spontaneously, this benefit must be weighed against the possible adverse reactions. Antibiotic treatment may play an important role in reducing the risk of mastoiditis in populations where it is more common.
