Tympanostomy tubes and developmental outcomes at 9 to 11 years of age.

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.

Reliability in assigning ICF codes to children with special health care needs using a developmentally structured interview.

PURPOSE: The purpose of this study was to determine if two teams of raters could reliably assign codes and performance qualifiers from the Activities and Participation component of the International Classification of Functioning, Disability, and Health (ICF) to children with special health care needs based on the results of a developmentally structured interview. METHOD: Children (N = 40), ages 11 months to 12 years 10 months, with a range of health conditions, were evaluated using a structured interview consisting of open-ended questions and scored using developmental guidelines. For each child, two raters made a binary decision indicating whether codes represented an area of need or no need for that child. Raters assigned a performance qualifier, based on the ICF guidelines, to each code designated as an area of need. Cohen's kappa statistic was used as the measure of inter-rater reliability. RESULTS: Team I reached good to excellent agreement on 39/39 codes and Team II on 38/39 codes. Team I reached good to excellent agreement on 5/5 qualifiers and Team II on 10/14 qualifiers. CONCLUSIONS: A developmentally structured interview was an effective clinical tool for assigning ICF codes to children with special health care needs. The interview resulted in higher rates of agreement than did results from standardized functional assessments. Guidelines for assigning performance qualifiers must be modified for use with children.

Developmental outcomes after early or delayed insertion of tympanostomy tubes.

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.

Treatment of attention-deficit/hyperactivity disorder: overview of the evidence.

The American Academy of Pediatrics' Committee on Quality Improvement, Subcommittee on Attention-Deficit/Hyperactivity Disorder, reviewed and analyzed the current literature for the purpose of developing an evidence-based clinical practice guideline for the treatment of the school-aged child with attention-deficit/hyperactivity disorder (ADHD). This review included several key reports, including an evidence review from the McMaster Evidence-Based Practice Center (supported by the Agency for Healthcare Research and Quality), a report from the Canadian Coordinating Office for Health Technology Assessment, the Multimodal Treatment for ADHD comparative clinical trial (supported by the National Institute of Mental Health), and supplemental reviews conducted by the subcommittee. These reviews provided substantial information about different treatments for ADHD and their efficacy in improving certain characteristics or outcomes for children with ADHD as well as adverse effects and benefits of multiple modes of treatment compared with single modes (eg, medication or behavior therapies alone). The reviews also compared the effects of different medications. Other evidence documents the long-term nature of ADHD in children and its classification as a chronic condition, meriting the application of general concepts of chronic-condition management, including an individual treatment plan with a focus on ongoing parent and child education, management, and monitoring. The evidence strongly supports the use of stimulant medications for treating the core symptoms of children with ADHD and, to a lesser degree, for improving functioning. Behavior therapy alone has only limited effect on symptoms or functioning of children with ADHD, although combining behavior therapy with medication seems to improve functioning and may decrease the amount of (stimulant) medication needed. Comparison among stimulants (mainly methylphenidate and amphetamines) did not indicate that 1 class outperformed the other.

Tympanic membrane abnormalities and hearing levels at the ages of 5 and 6 years in relation to persistent otitis media and tympanostomy tube insertion in the first 3 years of life: a prospective study incorporating a randomized clinical trial.

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.

Phonological memory and vocabulary learning in children with focal lesions.

Eleven children with early focal lesions were compared with 70 age-matched controls to assess their performance in repeating non-words, in learning new words, and in immediate serial recall, a triad of abilities that are believed to share a dependence on serial ordering mechanisms (e.g.,; ). Results for the experimental group were also compared with other assessments previously reported for the same children by. The children with brain injury showed substantial impairment relative to controls in the experimental tasks, in contrast with relatively unimpaired performance on measures of vocabulary and non-verbal intelligence. The relationships between word learning, non-word repetition, and immediate serial recall were similar to those observed in several other populations. These results support previous reports that there are persistent processing impairments following early brain injury, despite developmental plasticity. They also suggest that word learning, non-word repetition, and immediate serial recall may be relatively demanding tasks, and that their relationship is a fundamental aspect of the cognitive system.

Parent-reported language skills in relation to otitis media during the first 3 years of life.

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.

Early versus delayed insertion of tympanostomy tubes for persistent otitis media: developmental outcomes at the age of three years in relation to prerandomization illness patterns and hearing levels.

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.

Otitis media and tympanostomy tube insertion during the first three years of life: developmental outcomes at the age of four years.

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.

Sentence processing in children with early unilateral brain injury.

This study examined how children use word order and animacy cues to determine the agent of the action in an on-line sentence-comprehension task. The subject group included 15 children, 5-12 years old, with brain injury incurred prior to the age of 2 months; 12 had left hemisphere (LH) damage and 3 had right hemisphere (RH) damage. The comparison group included 141 children, 5-10 years old, who were at the appropriate grade for age. The task required children to listen to sentences composed of two noun phrases (N) that varied in terms of animacy and a verb phrase (V) and then to indicate the agent of the action. Three word orders were presented: NVN, VNN, and NNV. Measures included the proportion of trials in which the first noun was selected (choice) and reaction time. Word order and animacy significantly influenced choice. The effect of subject group approached significance for choice. Word order and age influenced reaction time. The children with LH injury and two children with RH injury showed a developmental delay in choosing the appropriate N as agent; one child with RH injury had mature responses. The overlapping performance of children with LH and RH injury suggests that delays in the development of sentence comprehension strategies are more likely related to reliance on a smaller than usual neural network rather than to congenital specialization of the LH.

Risk factors for speech delay of unknown origin in 3-year-old children.

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.

Concurrent and predictive validity of parent reports of child language at ages 2 and 3 years.

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.
