OBJECTIVES. Most children with sleep-disordered breathing (SDB) have mild-to-moderate forms, for which neurobehavioral complications are believed to be the most important adverse outcomes. To improve understanding of this morbidity, its long-term response to adenotonsillectomy, and its relationship to polysomnographic measures, we studied a series of children before and after clinically indicated adenotonsillectomy or unrelated surgical care. METHODS. We recorded sleep and assessed behavioral, cognitive, and psychiatric morbidity in 105 children 5.0 to 12.9 years old: 78 were scheduled for clinically indicated adenotonsillectomy, usually for suspected SDB, and 27 for unrelated surgical care. One year later, we repeated all assessments in 100 of these children. RESULTS. Subjects who had an adenotonsillectomy, in comparison to controls, were more hyperactive on well-validated parent rating scales, inattentive on cognitive testing, sleepy on the Multiple Sleep Latency Test, and likely to have attention-deficit/hyperactivity disorder (as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) as judged by a child psychiatrist. In contrast, 1 year later, the 2 groups showed no significant differences in the same measures. Subjects who had an adenotonsillectomy had improved substantially in all measures, and control subjects improved in none. However, polysomnographic assessment of baseline SDB and its subsequent amelioration did not clearly predict either baseline neurobehavioral morbidity or improvement in any area other than sleepiness. CONCLUSIONS. Children scheduled for adenotonsillectomy often have mild-to-moderate SDB and significant neurobehavioral morbidity, including hyperactivity, inattention, attention-deficit/hyperactivity disorder, and excessive daytime sleepiness, all of which tend to improve by 1 year after surgery. However, the lack of better correspondence between SDB measures and neurobehavioral outcomes suggests the need for better measures or improved understanding of underlying causal mechanisms.

It was hypothesized that those with systemic diseases such as diabetes mellitus would likely have higher prevalence rates of self-reported depressive symptoms than those diagnosed with nonsystemic diseases in part due to the disability conferred by their diagnosis. Analysis indicated partial support, although, other factors may moderate this relationship.

Social deficits in pediatric cancer survivors have been well documented and have been linked to neurocognitive late effects, particularly attention deficits. The purpose of this study was to examine the association between components of attention, both parent-report and a performance-based measure, with parent-reported social functioning in survivors of pediatric cancer. The study included data from outpatient neuropsychological evaluations of 76 survivors of pediatric cancer. The Integrated Visual and Auditory (IVA) continuous performance test was used to evaluate the components of attention with variables corresponding to Posner’s model of attention. Assessment of inattention and peer problems were derived from the Conner’s Parent Rating Scale, third edition. Parent-reported attention symptoms were significantly associated with worse auditory prudence (r = −0.382, p < .001) and visual consistency (r = −0.234, p = .046) and higher parent-reported peer problems (r = 0.302, p = .008). Auditory attention domains were not significantly predictive of peer problems (p > .05). When controlling for FSIQ and type of cancer, worse visual consistency (p = .029) and visual speed (p = .036) were significantly associated with more peer problems. Parent-reported inattention was associated with only some domains of performance-based attention, highlighting the importance of using multi-modal assessments of attention. This study also revealed an important relationship between visual attention and peer problems. [ABSTRACT FROM AUTHOR]

Objectives: To further validate a questionnaire about symptoms of childhood obstructive sleep apnea (OSA) and to compare the questionnaire with polysomnography in their ability to predict outcomes of adenotonsillectomy., Design: Retrospective analysis of data from a longitudinal study., Setting: University-based sleep disorders laboratory., Participants: The Washtenaw County Adenotonsillectomy Cohort, comprising 105 children aged 5.0 to 12.9 years at entry. Intervention Parents completed the 22-item Sleep-Related Breathing Disorder (SRBD) scale of the Pediatric Sleep Questionnaire, and children underwent polysomnography before and 1 year after clinically indicated adenotonsillectomy (n = 78, usually for suspected OSA) or unrelated surgical care (n = 27)., Main Outcome Measures: Findings from commonly used hyperactivity ratings, attention tests, and sleepiness tests., Results: At baseline, a high SRBD scale score (1 SD above the mean) predicted an approximately 3-fold increased risk of OSA on polysomnography (odds ratio, 2.80; 95% confidence interval, 1.68-4.68). One year later, OSA and symptoms had largely resolved, but a high SRBD score still predicted an approximately 2-fold increased risk of residual OSA on polysomnography (odds ratio, 1.89; 95% confidence interval, 1.13-3.18). Compared with several standard polysomnographic measures of OSA, the baseline SRBD scale better predicted initial hyperactivity ratings and 1-year improvement, similarly predicted sleepiness and its improvement, and similarly failed to predict attention deficit or its improvement., Conclusions: The SRBD scale predicts polysomnographic results to an extent useful for research but not reliable enough for most individual patients. However, the SRBD scale may predict OSA-related neurobehavioral morbidity and its response to adenotonsillectomy as well or better than does polysomnography.
