Abstract
BACKGROUND Young children with acute otitis media (AOM) frequently exhibit nasopharyngeal colonization with either Streptococcus pneumoniae, Haemophilus influenzae or both pathogens. We aimed to determine if antibiotics could be spared or shortened in those without nasopharyngeal colonization with either pathogen. METHODS In 2 separate randomized clinical trials in children aged 6-23 months with stringently-diagnosed AOM, we performed bacterial cultures on nasopharyngeal specimens collected at the time of diagnosis. In the first trial, we compared the efficacy of amoxicillin/clavulanate (amox/clav) administered for 10 days vs. that of placebo, and in the second trial, we compared the efficacy of amox/clav administered for 10 days vs. 5 days. In each trial, we classified children as being colonized with both S. pneumoniae and H. influenzae, S. pneumoniae alone, H. influenzae alone, or neither pathogen, and as experiencing either clinical success or clinical failure at the end-of-therapy visit, based on previously reported a priori criteria. RESULTS We evaluated 796 children. Among children randomized to amox/clav, those colonized with either S. pneumoniae or H. influenzae or both were approximately twice as likely to experience clinical failure as children not colonized with either pathogen (odds ratio: 1.8; confidence intervals: 1.2-2.9). In contrast, among children randomized to placebo, clinical failure at the end-of-therapy visit was not associated with nasopharyngeal culture results at the time of diagnosis. CONCLUSIONS Children colonized with either S. pneumoniae or H. influenzae or both have a greater chance of treatment failure than children colonized with neither pathogen.

Abstract
BACKGROUND Official recommendations differ regarding tympanostomy-tube placement for children with recurrent acute otitis media. METHODS We randomly assigned children 6 to 35 months of age who had had at least three episodes of acute otitis media within 6 months, or at least four episodes within 12 months with at least one episode within the preceding 6 months, to either undergo tympanostomy-tube placement or receive medical management involving episodic antimicrobial treatment. The primary outcome was the mean number of episodes of acute otitis media per child-year (rate) during a 2-year period. RESULTS In our main, intention-to-treat analysis, the rate (±SE) of episodes of acute otitis media per child-year during a 2-year period was 1.48±0.08 in the tympanostomy-tube group and 1.56±0.08 in the medical-management group (P = 0.66). Because 10% of the children in the tympanostomy-tube group did not undergo tympanostomy-tube placement and 16% of the children in the medical-management group underwent tympanostomy-tube placement at parental request, we conducted a per-protocol analysis, which gave corresponding episode rates of 1.47±0.08 and 1.72±0.11, respectively. Among secondary outcomes in the main analysis, results were mixed. Favoring tympanostomy-tube placement were the time to a first episode of acute otitis media, various episode-related clinical findings, and the percentage of children meeting specified criteria for treatment failure. Favoring medical management was children's cumulative number of days with otorrhea. Outcomes that did not show substantial differences included the frequency distribution of episodes of acute otitis media, the percentage of episodes considered to be severe, and antimicrobial resistance among respiratory isolates. Trial-related adverse events were limited to those included among the secondary outcomes of the trial. CONCLUSIONS Among children 6 to 35 months of age with recurrent acute otitis media, the rate of episodes of acute otitis media during a 2-year period was not significantly lower with tympanostomy-tube placement than with medical management.

Abstract
BACKGROUND Limiting the duration of antimicrobial treatment constitutes a potential strategy to reduce the risk of antimicrobial resistance among children with acute otitis media. METHODS We assigned 520 children, 6 to 23 months of age, with acute otitis media to receive amoxicillin-clavulanate either for a standard duration of 10 days or for a reduced duration of 5 days followed by placebo for 5 days. We measured rates of clinical response (in a systematic fashion, on the basis of signs and symptomatic response), recurrence, and nasopharyngeal colonization, and we analyzed episode outcomes using a noninferiority approach. Symptom scores ranged from 0 to 14, with higher numbers indicating more severe symptoms. RESULTS Children who were treated with amoxicillin-clavulanate for 5 days were more likely than those who were treated for 10 days to have clinical failure (77 of 229 children [34%] vs. 39 of 238 [16%]; difference, 17 percentage points [based on unrounded data]; 95% confidence interval, 9 to 25). The mean symptom scores over the period from day 6 to day 14 were 1.61 in the 5-day group and 1.34 in the 10-day group (P=0.07); the mean scores at the day-12-to-14 assessment were 1.89 versus 1.20 (P=0.001). The percentage of children whose symptom scores decreased more than 50% (indicating less severe symptoms) from baseline to the end of treatment was lower in the 5-day group than in the 10-day group (181 of 227 children [80%] vs. 211 of 233 [91%], P=0.003). We found no significant between-group differences in rates of recurrence, adverse events, or nasopharyngeal colonization with penicillin-nonsusceptible pathogens. Clinical-failure rates were greater among children who had been exposed to three or more children for 10 or more hours per week than among those with less exposure (P=0.02) and were also greater among children with infection in both ears than among those with infection in one ear (P<0.001). CONCLUSIONS Among children 6 to 23 months of age with acute otitis media, reduced-duration antimicrobial treatment resulted in less favorable outcomes than standard-duration treatment; in addition, neither the rate of adverse events nor the rate of emergence of antimicrobial resistance was lower with the shorter regimen.

Abstract
The objective of the present study was to determine whether changes in the previously developed 7-item Acute Otitis Media Severity of Symptoms scale could improve its responsiveness and its longitudinal construct validity. The items "diminished activity" and "diminished appetite" had low or borderline levels of responsiveness and longitudinal construct validity. Dropping these items seems to be potentially advantageous.

Abstract
BACKGROUND We previously developed and validated the acute otitis media severity of symptom (AOM-SOS) scale for rating symptoms of AOM in young children. In this report, we sought to estimate the minimal important difference (MID) for change in AOM-SOS scores. METHODS In a group of children 6-24 months of age with AOM enrolled in a recently reported placebo-controlled clinical trial of antibiotic efficacy, we compared changes in AOM-SOS scores with parental assessments of change over a 24-hour period. Mean absolute and mean relative change in scores in children reportedly exhibiting only a small degree of improvement were considered in arriving at an estimated MID. We then compared the proportions of children in the antibiotic and placebo groups, respectively, whose AOM-SOS scores changed more than the estimated MID at various time points after enrollment. RESULTS Data were available for 277 children. Children whose parents reported only a small degree of improvement 24 hours after enrollment had a mean decrease in AOM-SOS score of 3.8, or 55%, from baseline. We found the relative decrease more telling than the absolute decrease. The proportions of children in the antibiotic and placebo groups, respectively, whose AOM-SOS scores had decreased <55% on Day 7 were 12.3 and 23.8% (P=0.02), and during Days 4-7 were 28 and 40% (P=0.046). CONCLUSIONS We estimated the MID for change in AOM-SOS scores in young children and described use of the MID as an added metric in interpreting results from a clinical trial of antibiotic efficacy.

Abstract
METHODS Before and after introduction of pneumococcal conjugate vaccine (PCV7), the authors obtained nasopharyngeal (NP) specimens from 3 groups of children aged 6 to 23 months with acute otitis media (AOM): group 1 (pre-PCV7), group 2 (early post-PCV7), and group 3 (late post-PCV7). RESULTS Of the Streptococcus pneumoniae isolates, the proportion that were vaccine serotypes (VTs) declined progressively (60.4% vs 48.6% vs 5.2% in groups 1, 2, and 3, respectively; P < .001). Concurrently, increases occurred in the proportion of penicillin-nonsusceptible isolates (minimum inhibitory concentration >0.1 µg/mL; 26.7% vs 37.8% vs. 38.5%; P = .12); the proportion of isolates that were serotype 19A (4.0% vs 0% vs 25.9%; P < .001); and the proportion of 19A isolates that were penicillin-nonsusceptible (0% in group 1, 68.6% in group 3; P = .004). CONCLUSION Shifts in pneumococcal serotype distribution and increases in penicillin nonsusceptibility among pneumococcal isolates from children with AOM underscore the need for continuing bacteriological surveillance for future vaccine development.

Abstract
BACKGROUND Recommendations vary regarding immediate antimicrobial treatment versus watchful waiting for children younger than 2 years of age with acute otitis media. METHODS We randomly assigned 291 children 6 to 23 months of age, with acute otitis media diagnosed with the use of stringent criteria, to receive amoxicillin-clavulanate or placebo for 10 days. We measured symptomatic response and rates of clinical failure. RESULTS Among the children who received amoxicillin-clavulanate, 35% had initial resolution of symptoms by day 2, 61% by day 4, and 80% by day 7; among children who received placebo, 28% had initial resolution of symptoms by day 2, 54% by day 4, and 74% by day 7 (P=0.14 for the overall comparison). For sustained resolution of symptoms, the corresponding values were 20%, 41%, and 67% with amoxicillin-clavulanate, as compared with 14%, 36%, and 53% with placebo (P=0.04 for the overall comparison). Mean symptom scores over the first 7 days were lower for the children treated with amoxicillin-clavulanate than for those who received placebo (P=0.02). The rate of clinical failure--defined as the persistence of signs of acute infection on otoscopic examination--was also lower among the children treated with amoxicillin-clavulanate than among those who received placebo: 4% versus 23% at or before the visit on day 4 or 5 (P<0.001) and 16% versus 51% at or before the visit on day 10 to 12 (P<0.001). Mastoiditis developed in one child who received placebo. Diarrhea and diaper-area dermatitis were more common among children who received amoxicillin-clavulanate. There were no significant changes in either group in the rates of nasopharyngeal colonization with nonsusceptible Streptococcus pneumoniae. CONCLUSIONS Among children 6 to 23 months of age with acute otitis media, treatment with amoxicillin-clavulanate for 10 days tended to reduce the time to resolution of symptoms and reduced the overall symptom burden and the rate of persistent signs of acute infection on otoscopic examination.

Abstract
OBJECTIVE We developed a program for training in the diagnosis of otitis media that included images illustrating various otoscopic findings, mnemonic guides to recollection, and discrimination sessions that included feedback and assessments of diagnostic skills. METHODS We prepared a computerized, interactive curriculum, Enhancing Proficiency in Otitis Media (ePROM), that was centered around assemblages of clinically diverse, still and video images of tympanic membranes (TMs). To assess curriculum effectiveness, we constructed a test, the Diagnostic Ear Assessment Resource, that consisted of 50 video TM images. We administered the test to 84 residents in pediatrics or family practice who had not been exposed to ePROM and, varying the order in which the images were presented, to another group of 102 residents in the same programs both before and after exposure to ePROM. RESULTS o Mean proportions of correct diagnoses in the Diagnostic Ear Assessment Resource were larger among residents who had been exposed to ePROM than among residents at comparable levels of training who had not been exposed (67% vs 62%; P = .007). Among residents exposed to ePROM, mean proportions of correct diagnoses were larger after exposure than before (67% vs 55%; P < .001). CONCLUSION A structured, computerized curriculum to supplement standard clinical training can enhance residents' abilities to interpret still and video images of TMs and may improve their skills in diagnosing otitis media.

Abstract
OBJECTIVE New vaccines that offer protection against otitis media caused by nontypeable Haemophilus influenzae and by Moraxella catarrhalis are under development. However, the potential health benefits and economic effects of such candidate vaccines have not been systematically assessed. METHODS We created a computerized model to compare the projected benefits and costs of (1) the currently available 7-valent pneumococcal conjugate vaccine, (2) a candidate pneumococcal-nontypeable H influenzae vaccine that has been tested in Europe, (3) a hypothetical pneumococcal-nontypeable H influenzae-Moraxella vaccine, and (4) no vaccination. The clinical probabilities of acute otitis media and of otitis media with effusion were generated from multivariate analyses of data from 2 large health maintenance organizations and from the Pittsburgh Child Development/Otitis Media Study cohort. Other probabilities, costs, and quality-of-life values were derived from published and unpublished sources. The base-case analysis assumed vaccine dose costs of $65 for the 7-valent pneumococcal conjugate vaccine, $100 for the pneumococcal-nontypeable H influenzae vaccine, and $125 for the pneumococcal-nontypeable H influenzae-Moraxella vaccine. RESULTS With no vaccination, we projected that 13.7 million episodes of acute otitis media would occur annually in US children aged 0 to 4 years, at an annual cost of $3.8 billion. The 7-valent pneumococcal conjugate vaccine was projected to prevent 878,000 acute otitis media episodes, or 6.4% of those that would occur with no vaccination; the corresponding value for the pneumococcal-nontypeable H influenzae vaccine was 3.7 million (27%) and for the pneumococcal-nontypeable H influenzae-Moraxella vaccine was 4.2 million (31%). Using the base-case vaccine costs, pneumococcal-nontypeable H influenzae vaccine use would result in net savings compared with nontypeable 7-valent pneumococcal conjugate use. Conversely, pneumococcal-nontypeable H influenzae-Moraxella vaccine use would not result in savings compared with pneumococcal-nontypeable H influenzae vaccine use, but would cost $48 000 more per quality-adjusted life-year saved. The results were sensitive to variations in assumptions on vaccine effectiveness and vaccine dose costs but not to variations in other assumptions. CONCLUSIONS New candidate vaccines against otitis media have the potential to prevent millions of disease episodes in the United States annually. If priced comparably with other recently introduced vaccines, these new otitis vaccines could achieve cost-effectiveness comparable with or more favorable than that of the 7-valent pneumococcal conjugate vaccine.

Abstract
In a prospective study of developmental outcomes in relation to early-life otitis media, behavioral, cognitive, and language measures were administered to a large, diverse sample of children at 2, 3, 4, 6, and 9-11 years of age (N = 741). At 9-11 years of age, 9% of the children were categorized as having attention-deficit/hyperactivity disorder (ADHD) based on parent report. Compared to the non-ADHD group, the ADHD group had higher (i.e., less favorable) scores on parent and teacher versions of the Child Behavior Checklist at all ages. Children in the ADHD group also had lower scores on cognitive and receptive language measures in preschool. The findings support the concept that ADHD is a cognitive as well as a behavioral disorder.

Abstract
OBJECTIVES To evaluate the accuracy of spectral gradient acoustic reflectometry (SGAR) in children aged 6 to 24 months, and to compare SGAR with tympanometry. DESIGN Comparison of diagnostic tests. SETTING Inner-city primary care center in Pittsburgh, Pennsylvania. PARTICIPANTS A total of 786 healthy children aged 6 to 24 months. MAIN OUTCOME MEASURES Test characteristics of SGAR (sensitivity, specificity, and positive and negative predictive values) and receiver operating characteristic curves from the SGAR and tympanometric data. RESULTS The SGAR results were available for 3096 otoscopic examinations in 647 children. Tympanometric results were available for 2854 otoscopic examinations in 597 children. Using the recommended SGAR pass or fail cutoff, 53% of the ears in which effusion was present would have been considered effusion free (sensitivity, 47%). Only 10% of the ears without effusion would have been considered to have effusion (specificity, 90%). The area under the receiver operating characteristic curve was 0.78 for SGAR and 0.83 for tympanometry. CONCLUSION Spectral gradient acoustic reflectometry is slightly less discerning than tympanometry in predicting the presence or absence of middle ear effusion in children younger than 2 years.

Abstract
BACKGROUND Developmental impairments in children have been attributed to persistent middle-ear effusion in their early years of life. Previously, we reported that among children younger than 3 years of age with persistent middle-ear effusion, prompt as compared with delayed insertion of tympanostomy tubes did not result in improved cognitive, language, speech, or psychosocial development at 3, 4, or 6 years of age. However, other important components of development could not be assessed until the children were older. METHODS We enrolled 6350 infants soon after birth and evaluated them regularly for middle-ear effusion. Before 3 years of age, 429 children with persistent effusion were randomly assigned to undergo the insertion of tympanostomy tubes either promptly or up to 9 months later if effusion persisted. We assessed literacy, attention, social skills, and academic achievement in 391 of these children at 9 to 11 years of age. RESULTS Mean (+/-SD) scores on 48 developmental measures in the group of children who were assigned to undergo early insertion of tympanostomy tubes did not differ significantly from the scores in the group that was assigned to undergo delayed insertion. These measures included the Passage Comprehension subtest of the Woodcock Reading Mastery Tests (mean score, 98+/-12 in the early-treatment group and 99+/-12 in the delayed-treatment group); the Spelling, Writing Samples, and Calculation subtests of the Woodcock-Johnson III Tests of Achievement (96+/-13 and 97+/-16; 104+/-14 and 105+/-15; and 99+/-13 and 99+/-13, respectively); and inattention ratings on visual and auditory continuous performance tests. CONCLUSIONS In otherwise healthy young children who have persistent middle-ear effusion, as defined in our study, prompt insertion of tympanostomy tubes does not improve developmental outcomes up to 9 to 11 years of age.

Abstract
OBJECTIVE We examined relationships between tympanometric findings and the presence or absence of middle-ear effusion in a population-based sample of children under the age of 3 years. METHODS In a study of children's development in relation to early-life otitis media, we enrolled 6350 infants soon after birth and evaluated them regularly for the presence of middle-ear effusion. In 3686 of the children, we compared tympanometric findings with otoscopic diagnoses. We categorized tympanograms according to varying combinations of tympanometric peak height, peak pressure, and width, and calculated for each resulting category the percentage of the associated ears diagnosed as having effusion. Using these findings we developed algorithms for estimating the probability of middle-ear effusion associated with tympanograms of any configuration. RESULTS For tympanograms generally, the lower their height and the greater their width, the greater was the probability of associated middle-ear effusion; the probability also was greater when peak pressure was negative rather than positive. Among children > or = 6 months of age, effusion was diagnosed in only 2.7% of ears with tympanometric height > or = 0.6 mL, but in 80.2% of ears with flat tympanograms. Relationships among younger infants were similar but less consistent. In both age groups, the tympanographic configurations most commonly encountered were associated with either a relatively low probability (<30%) or a relatively high probability (>70%) of the presence of middle-ear effusion. The receiver operating characteristic curve we generated using the algorithm we developed for children > or = 6 months of age gave an area under the curve of 0.84. The algorithm performed equally well when applied to a separate group of children, suggesting that it is generalizable to other unselected populations. CONCLUSIONS The present report offers two alternative methods for estimating the probability of middle-ear effusion in children aged 6 through 35 months, given any combination of tympanometric values.

Abstract
The MacArthur-Bates Communicative Development Inventories (CDI; Dale, 1996; Fenson et al., 1994), parent reports about language skills, are being used increasingly in studies of theoretical and public health importance. This study (N = 113) correlated scores on the CDI at ages 2 and 3 years with scores at age 3 years on tests of cognition and receptive language and measures from parent-child conversation. Associations indicated reasonable concurrent and predictive validity. The findings suggest that satisfactory vocabulary scores at age 2 are likely to predict normal language skills at age 3, although some children with limited skills at age 3 will have had satisfactory scores at age 2. Many children with poor vocabulary scores at 2 will have normal skills at 3.

Abstract
BACKGROUND To prevent later developmental impairments, myringotomy with the insertion of tympanostomy tubes has often been undertaken in young children who have persistent otitis media with effusion. We previously reported that prompt as compared with delayed insertion of tympanostomy tubes in children with persistent effusion who were younger than three years of age did not result in improved developmental outcomes at three or four years of age. However, the effect on the outcomes of school-age children is unknown. METHODS We enrolled 6350 healthy infants younger than 62 days of age and evaluated them regularly for middle-ear effusion. Before three years of age, 429 children with persistent middle-ear effusion were randomly assigned to have tympanostomy tubes inserted either promptly or up to nine months later if effusion persisted. We assessed developmental outcomes in 395 of these children at six years of age. RESULTS At six years of age, 85 percent of children in the early-treatment group and 41 percent in the delayed-treatment group had received tympanostomy tubes. There were no significant differences in mean (+/-SD) scores favoring early versus delayed treatment on any of 30 measures, including the Wechsler Full-Scale Intelligence Quotient (98+/-13 vs. 98+/-14); Number of Different Words test, a measure of word diversity (183+/-36 vs. 175+/-36); Percentage of Consonants Correct-Revised test, a measure of speech-sound production (96+/-2 vs. 96+/-3); the SCAN test, a measure of central auditory processing (95+/-15 vs. 96+/-14); and several measures of behavior and emotion. CONCLUSIONS In otherwise healthy children younger than three years of age who have persistent middle-ear effusion within the duration of effusion that we studied, prompt insertion of tympanostomy tubes does not improve developmental outcomes at six years of age.

Abstract
BACKGROUND During the past decade, the prevalence of nonsusceptible Streptococcus pneumoniae strains that cause acute otitis media (AOM) has increased to approximately 30%, and the proportion of fully resistant strains has also increased. The purpose of this study was to determine whether seasonal variation in resistance exists among pneumococcal isolates from children with AOM. METHODS Between 1991 and 2003, children 2 months-8 years of age diagnosed with AOM according to stringent criteria underwent tympanocentesis in various clinical trials. RESULTS Cultures from 567 of 794 tympanocenteses (71.4%) performed between 1991 and 2003 yielded AOM pathogens. During 1991-1995, only 1 of 43 S. pneumoniae isolates recovered (2%) was nonsusceptible to penicillin. The present analysis focuses on the 691 cultures obtained during 1996-2003; of these, 491 (71.1%) yielded AOM pathogens, of which 165 (33.6%) were S. pneumoniae. Of the pneumococcal isolates, 52 (31.5%) were nonsusceptible to penicillin. The proportion of nonsusceptible strains of S. pneumoniae increased over time: 0 of 3 (0%) in 1996; 2 of 11 (18%) in 1997; 14 of 40 (35%) in 1998; 3 of 34 (9%) in 1999; 11 of 25 (44%) in 2000; 11 of 22 (50%) in 2001; 4 of 18 (22%) in 2002; and 7 of 12 (58%) in 2003 (Cochran Armitage trend test, P = 0.03). AOM caused by nonsusceptible S. pneumoniae was more likely to occur as the winter progressed (P = 0.03); a similar trend was noted for the proportion of nonsusceptible strains that were fully resistant. CONCLUSIONS In children with AOM, an increase in the proportion of episodes caused by nonsusceptible S. pneumoniae as the winter months progress may serve as a potential factor in guiding antimicrobial therapy for such children.

Abstract
OBJECTIVE One current practice guideline recommends myringotomy with tympanostomy tube insertion (M&T) for young children in whom middle-ear effusion (MEE) has persisted for 3 months, and another recommends the procedure after MEE has persisted for 4 to 6 months provided that a bilateral hearing loss of > or=20 dB is present. Sequelae of M&T are not uncommon, but the extent to which these sequelae are attributable to M&T itself or to the middle-ear disease that prompted the procedure or to both has not been clear. Our objective in the present study was to examine the prevalence of various tympanic membrane (TM) abnormalities in otherwise healthy children at the age of 5 years and hearing levels at the age of 6 years in relation to persistent MEE and M&T in the children's first 3 years of life. METHODS In a prospective study of child development in relation to early-life otitis media, we randomly assigned 429 children who met specified criteria regarding the persistence of MEE in their first 3 years of life to undergo M&T either promptly (the "early-treatment" group) or after a defined extended period if MEE remained present (the "late-treatment" group). We also followed a representative sample of 241 children who ranged from having no MEE to having MEE whose cumulative duration fell just short of meeting randomization criteria for the clinical trial (the "nontrial" group). Most of the children in each group underwent both otomicroscopic examination at the age of 5 years and audiometric testing at the age of 6 years, at times when they were free of MEE. Among these children, M&T had been performed in 82.3% of those in the early-treatment group, 38.1% of those in the late-treatment group, and 3.0% of those in the nontrial group. RESULTS At the age of 5 years, we found 1 or more types of TM abnormality in 1 or both ears in 70.7%, 42.5%, and 9.5% of the children in the early-treatment, late-treatment, and nontrial groups, respectively. Within the 3 groups, however, among children who received tubes, the proportions who had an abnormality of some type were similar, namely, 82.6%, 80.4%, and 83.3%, respectively. The corresponding proportions among children who had not received tubes were 15.4%, 19.3%, and 7.2%, respectively. Segmental atrophy and tympanosclerosis were the most common abnormalities found. At the age of 6 years, mean pure-tone average audiometric thresholds in the early-treatment, late-treatment, and nontrial groups, respectively, were 6.18 dB, 5.49 dB, and 4.63 dB in left ears and 6.17 dB, 6.02 dB, and 4.32 dB in right ears. The thresholds in the early- and late-treatment groups did not differ significantly, but the thresholds in the early- and late-treatment groups were each significantly higher than in the nontrial group. Within the early- and late-treatment groups, we found no significant relation between hearing levels and the presence or type of TM abnormalities. CONCLUSION In otherwise healthy children who have persistent MEE during their first 3 years of life, ready resort to M&T results in far more TM abnormalities at age 5 than does selective management in which most children do not receive the procedure. With these differing approaches, however, hearing levels at age 6 do not differ. Regardless of whether children with persistent early-life MEE receive M&T, they have more TM abnormalities at age 5 and negligibly poorer hearing at age 6 than do children who had less or no otitis media. Longer term otologic and audiologic outcomes of persistent early-life MEE and of M&T remain to be determined. In view of 1) the present findings and the remaining uncertainties concerning sequelae, 2) the fact that M&T involves certain immediate risks--albeit minimal--and substantial cost, and 3) previously reported findings in the study's randomized clinical trial that show no developmental advantage at ages 3 and 4 years accruing from children's having received prompt M&T, a prolonged period of watchful waiting seems desirable in otherwise healthy children who are younger than 3 years and have persistent, asymptomatic MEE that is not complicated by sensorineural or severe conductive hearing loss, balance dysfunction, or severe TM retraction.

Abstract
CONTEXT Acute otitis media (AOM) frequently complicates influenza infection. Previous studies have found influenza vaccine effective in reducing the occurrence of AOM in children mainly older than 2 years. OBJECTIVE To evaluate the effectiveness of inactivated influenza vaccine in preventing AOM in children aged 6 to 24 months. DESIGN, SETTING, AND PATIENTS Randomized, double-blind, placebo-controlled trial of 786 children aged 6 to 24 months enrolled at Children's Hospital of Pittsburgh before the 1999-2000 (411 children) and 2000-2001 (375 children) respiratory seasons (defined as December 1 through March 31 of the respective following year). Children received influenza vaccine or placebo in a 2:1 ratio. The first cohort was observed for 1 year and the second cohort until the end of the ensuing respiratory season. INTERVENTION Two doses (0.25 mL each) of inactivated trivalent subvirion influenza vaccine or placebo were administered intramuscularly approximately 4 weeks apart. MAIN OUTCOME MEASURES Proportion of children who developed AOM, monthly occurrence rate of AOM, estimated proportion of time with middle ear effusion, and utilization of selected health care and related resources. RESULTS Of the 66 children in the vaccine group from whom serum samples were collected, seroconversion against strains in the vaccine formulations developed in 88.6% to 96.8%, depending on the specific strain. The efficacy of the vaccine against culture-confirmed influenza was 66% (95% confidence interval [CI], 34%-82%) in 1999-2000 and -7% (95% CI, -247% to 67%) in 2000-2001; however, influenza attack rates differed between these 2 periods (in the placebo group, 15.9% and 3.3%, respectively). Compared with placebo, influenza vaccine did not reduce the proportion of children who had at least 1 episode of AOM during the respiratory season (in the first cohort: vaccine, 49.2% vs placebo, 52.2%; P =.56 ]; in the second cohort: vaccine, 55.8% vs placebo, 48.3%; P =.17). The vaccine also did not reduce the monthly rate of AOM; the estimated proportion of time with middle ear effusion; or the utilization of selected health care and related resources. There were also no differences between the vaccine and placebo groups regarding any of these outcomes during peak influenza periods. The vaccines administered to both cohorts of children were well tolerated. CONCLUSION Administration of inactivated trivalent influenza vaccine to children aged 6 to 24 months did not reduce their burden of AOM or their utilization of selected health care and related resources.

Abstract
OBJECTIVE In a long-term, prospective study, we set out to determine whether otitis media in the first 3 years of life persisting for periods currently considered developmentally threatening actually results in later impairments of children's cognitive, language, speech, or psychosocial development; whether prompt insertion of tympanostomy tubes prevents or lessens any such impairments; and whether, irrespective of causality, associations exist between persistent early-life otitis media and later developmental impairments. This report describes findings in study participants at the age of 4 years. METHODS We enrolled 6350 healthy infants from 2 to 61 days of age at urban hospitals and 2 small-town/rural and 4 suburban private pediatric practices. We regularly evaluated the children for the presence of middle-ear effusion (MEE) throughout their first 3 years of life by pneumatic otoscopy, supplemented by tympanometry; we monitored the validity of the otoscopic observations on an ongoing basis; and we treated children for otitis media according to specified guidelines. In the clinical trial component of the study, we randomly assigned 429 children who met specified minimum criteria regarding the persistence of MEE to undergo tympanostomy tube insertion either promptly or after a defined extended period if MEE remained present. In the associational component of the study, we selected a representative sample of 241 children who ranged from having no MEE to having MEE the cumulative duration of which fell just short of meeting randomization criteria for the clinical trial. In 397 (92.5%) of the children in the clinical trial and in 234 (97.1%) of the children in the representative sample, we assessed cognitive, language, speech, and psychosocial development at the age of 4 years, using formal tests, conversational samples, and parent questionnaires. RESULTS In children in the randomized clinical trial, there were no statistically significant differences in mean (+/-standard deviation) scores (higher denotes more favorable) favoring the early-treatment group over the late-treatment group on the General Cognitive Index of the McCarthy Scales of Children's Abilities (97 +/- 14 and 98 +/- 14, respectively); the Peabody Picture Vocabulary Test-Revised, a measure of receptive language (90 +/- 15 vs 92 +/- 16); the Nonword Repetition Test, a measure of phonological memory (66 +/- 12 vs 70 +/- 12); the Number of Different Words, a measure of word diversity (150 +/- 34 vs 150 +/- 31); the Mean Length of Utterance in Morphemes, a measure of sentence length and grammatical complexity (3.4 +/- 0.8 vs 3.4 +/- 0.7); or the Percentage of Consonants Correct-Revised, a measure of speech-sound production (92 +/- 5 vs 93 +/- 5). There were also no significant differences in ratings (higher denotes less favorable) on the Parenting Stress Index-Short Form (Total Stress scores: 68 +/- 18 vs 65 +/- 17) or the Child Behavior Checklist (Total Problem T scores: 50 +/- 10 vs 49 +/- 10). In the associational component of the study, correlations between the children's durations of MEE and their developmental outcomes were generally weak and, in most instances, nonsignificant. Exceptions, after adjustment for sociodemographic variables and for hearing thresholds at the time of developmental testing, consisted of a significant negative correlation between children's cumulative durations of MEE in their first 3 years of life and scores on the McCarthy Verbal subscale, and significant positive correlations between durations of MEE and scores on 2 measures of parent-child stress. The percentage of variance in these scores explained by time with MEE beyond that explained by sociodemographic variables ranged from 1.6% to 3.3%. In both the randomized clinical trial and the associational component, sociodemographic variables seemed to be the most important factors influencing developmental outcomes, and in both components, the results at 4 years of age were consistent with the results that had been obtained at 3 years of age. CONCLUSIONS In otherwise healthy children who are younger than 3 years and have persistent MEE within the duration limits that we studied, prompt insertion of tympanostomy tubes does not measurably improve developmental outcomes at 4 years of age. In such children, persistent MEE within the duration limits that we studied is negligibly associated with and probably does not affect developmental outcomes at 4 years of age.

Abstract
BACKGROUND Whether prompt insertion of tympanostomy tubes in children with persistent early life otitis media prevents or minimizes subsequent developmental impairment has been the subject of conflicting opinions and differing approaches to management. METHODS We randomly assigned 429 children with persistent middle ear effusion (MEE) before the age of 3 years to have tympanostomy tubes inserted either as soon as possible or up to 9 months later if MEE persisted. In 402 of these children, we found no significant differences at age 3 years between the 2 treatment groups in mean scores on any measure of speech, language and cognition and in 401 of the children no significant differences in measures of psychosocial development. We then examined outcomes within subgroups of children who might have been the most severely affected, namely those who had been randomized on the basis of bilateral, continuous MEE rather than unilateral and/or discontinuous MEE and those who had the greatest degrees of hearing loss. RESULTS In none of the subgroups we considered were scores on any outcome measure significantly more favorable in children in the early treatment group than in children in the late treatment group. CONCLUSIONS In otherwise normal children who have MEE, during the first 3 years of life within the durations we studied, prompt insertion of tympanostomy tubes does not measurably improve developmental outcomes at age 3 years, irrespective of whether MEE has been continuous or discontinuous and unilateral or bilateral and whether or not MEE has been accompanied by mild to moderate hearing loss.

Parent-reported language skills in relation to otitis media during the first 3 years of life. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2003; 46:273-287.

Abstract
As part of a larger study of the potential impact of early-life otitis media (OM) on speech, language, cognition, and behavior, we studied the degree of association between parent-reported language scores at ages 1, 2, and 3 years and the cumulative duration of middle-ear effusion (MEE) during the first 3 years of life in a demographically diverse sample of 621 children. We estimated the cumulative percentage of days with MEE from prospective monthly observations of middle-ear status and interpolations for periods between visits. For each child, parents completed the appropriate inventory of the MacArthur Communicative Development Inventories (CDI; L. Fenson et al., 1993) at ages 1, 2, and 3 years. We also evaluated the contribution of maternal education, as a proxy for socioeconomic status, to scores on the parent reports. Scores on the new CDI-III (B. Oliver et al., in press) varied positively with sociodemographic variables and were significantly correlated with scores from the CDI used when the children were younger. Unadjusted correlations between scores at ages 1 and 2 years and the percentages of days with MEE in the respective antecedent periods were statistically nonsignificant or of questionable clinical importance. The correlations between parent-reported scores at age 3 years and children's cumulative percentage of days with MEE in Years 1, 2, and 3 combined ranged from -.187 to -.248 (all p values < .001). The percentage of days with MEE and maternal education each contributed independently to scores at age 3 years. In the light of other findings from the larger study, we think it likely that the negative associations between language measures and MEE reflect confounding factors that contribute, on the one hand, to the duration of OM in young children and, on the other hand, to slow development of their language skills.

Abstract
One hundred 3-year-olds with speech delay of unknown origin and 539 same-age peers were compared with respect to 6 variables linked to speech disorders: male sex, family history of developmental communication disorder, low maternal education, low socioeconomic status (indexed by Medicaid health insurance), African American race, and prolonged otitis media. Abnormal hearing was also examined in a subset of 279 children who had at least 2 hearing evaluations between 6 and 18 months of age. Significant odds ratios were found only for low maternal education, male sex, and positive family history; a child with all 3 factors was 7.71 times as likely to have a speech delay as a child without any of these factors.

Abstract
OBJECTIVE As part of a prospective study of possible effects of early-life otitis media on speech, language, cognition, and psychosocial development, we evaluated hearing both during episodes of middle-ear effusion (MEE) and when MEE was not present. The objective of this report is to describe age-specific hearing threshold levels in relation to the presence or absence of MEE in a large sample of young children. DESIGN Participants were 1,055 children drawn from a sample of 6,350 children who were enrolled in the larger study by 2 mo of age. Otologic evaluation of each child was conducted at least monthly. The protocol of the larger study called for hearing evaluations 1) after 8 wk of continuous unilateral or bilateral MEE and every 4 wk thereafter until one test had been conducted when MEE was no longer present; 2) immediately before developmental testing; and 3) in a sample of children without MEE to obtain age-specific normative data. RESULTS Results are presented by testing technique, age group, and middle-ear condition. In general, hearing threshold levels were highest in the youngest children tested with visual reinforcement audiometry and lowest in the oldest children tested with conventional audiometry. In general also, thresholds were lowest in children with normal middle-ear status, intermediate in children with unilateral MEE, and highest in children with bilateral MEE. On average, the presence of bilateral MEE was associated with hearing threshold levels 10 to 15 dB higher than the normative values for the corresponding age group. CONCLUSIONS In infants and young children, audiometric results are influenced by testing technique, age group, and the presence or absence of effusion in each ear.

Abstract
OBJECTIVE In previous clinical trials involving children severely affected with recurrent throat infection (7 or more well-documented, clinically important, adequately treated episodes of throat infection in the preceding year, or 5 or more such episodes in each of the 2 preceding years, or 3 or more such episodes in each of the 3 preceding years), we found tonsillectomy efficacious in reducing the number and severity of subsequent episodes of throat infection for at least 2 years. The results seemed to warrant the election of tonsillectomy in children meeting the trials' stringent eligibility criteria but also provided support for nonsurgical management. We undertook the present trials to determine 1) whether tonsillectomy would afford equivalent benefit in children who were less severely affected than those in our earlier trials but who nonetheless had indications for tonsillectomy comparable to those in general use, and 2) whether, in such children, the addition of adenoidectomy would confer additional benefit. METHODS We conducted 2 parallel randomized, controlled trials in the Ambulatory Care Center of Children's Hospital of Pittsburgh. To be eligible, children were required to have had a history of recurrent episodes of throat infection that met standards slightly less stringent than the standards used in our earlier trials regarding either the frequency of previous episodes or their clinical features or their degree of documentation, but not regarding >1 of those parameters. These reduced standards were nonetheless more stringent than those in current official guidelines, which list "3 or more infections of tonsils and/or adenoids per year despite adequate medical therapy" as an indication for tonsillectomy or adenotonsillectomy. Of 2174 children referred by physicians or parents, 373 met the current trials' eligibility criteria and 328 were enrolled. Of these, 177 children without obstructing adenoids or recurrent or persistent otitis media were randomized to either a tonsillectomy group, an adenotonsillectomy group, or a control group (the 3-way trial), and 151 children who had 1 or more such conditions were randomized to either an adenotonsillectomy group or a control group (the 2-way trial). Outcome measures were the occurrence of episodes of throat infection during the 3 years of follow-up; other, indirect measures of morbidity; and complications of surgery. RESULTS By various measures, the incidence of throat infection was significantly lower in surgical groups than in corresponding control groups during each of the 3 follow-up years. However, even among control children, mean rates of moderate or severe episodes were low, ranging from 0.16 to 0.43 per year. Adenotonsillectomy was no more efficacious than tonsillectomy alone. Of 203 children treated with surgery, 16 (7.9%) had surgery-related complications of varying types and severity. CONCLUSIONS The modest benefit conferred by tonsillectomy or adenotonsillectomy in children moderately affected with recurrent throat infection seems not to justify the inherent risks, morbidity, and cost of the operations. We conclude that, under ordinary circumstances, neither eligibility criteria such as those used for the present trials nor the criterion for surgery in current official guidelines are sufficiently stringent for use in clinical practice.
