A randomized trial of adenotonsillectomy for childhood sleep apnea.

BACKGROUND: Adenotonsillectomy is commonly performed in children with the obstructive sleep apnea syndrome, yet its usefulness in reducing symptoms and improving cognition, behavior, quality of life, and polysomnographic findings has not been rigorously evaluated. We hypothesized that, in children with the obstructive sleep apnea syndrome without prolonged oxyhemoglobin desaturation, early adenotonsillectomy, as compared with watchful waiting with supportive care, would result in improved outcomes. METHODS: We randomly assigned 464 children, 5 to 9 years of age, with the obstructive sleep apnea syndrome to early adenotonsillectomy or a strategy of watchful waiting. Polysomnographic, cognitive, behavioral, and health outcomes were assessed at baseline and at 7 months. RESULTS: The average baseline value for the primary outcome, the attention and executive-function score on the Developmental Neuropsychological Assessment (with scores ranging from 50 to 150 and higher scores indicating better functioning), was close to the population mean of 100, and the change from baseline to follow-up did not differ significantly according to study group (mean [±SD] improvement, 7.1±13.9 in the early-adenotonsillectomy group and 5.1±13.4 in the watchful-waiting group; P=0.16). In contrast, there were significantly greater improvements in behavioral, quality-of-life, and polysomnographic findings and significantly greater reduction in symptoms in the early-adenotonsillectomy group than in the watchful-waiting group. Normalization of polysomnographic findings was observed in a larger proportion of children in the early-adenotonsillectomy group than in the watchful-waiting group (79% vs. 46%). CONCLUSIONS: As compared with a strategy of watchful waiting, surgical treatment for the obstructive sleep apnea syndrome in school-age children did not significantly improve attention or executive function as measured by neuropsychological testing but did reduce symptoms and improve secondary outcomes of behavior, quality of life, and polysomnographic findings, thus providing evidence of beneficial effects of early adenotonsillectomy.

Effect of Speaking Valves on Tracheostomy Decannulation.

Introduction Despite several pediatric tracheostomy decannulation protocols there remains tremendous variability in practice. The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] = 3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis ( p = 0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.

Pediatric Pulmonary Milestones 2.0: Development, Lessons Learned, and Future Directions.

Pediatric pulmonology fellowship training programs are required by the Accreditation Council for Graduate Medical Education to report Pediatric Subspecialty Milestones biannually to track fellow progress. However, several issues, such as lack of subspecialty-specific context and ambiguous language, have raised concerns about their validity and applicability to use for fellow assessment and curriculum development. In this Perspective, we briefly share the process of the Pediatric Pulmonology Milestones 2.0 Work Group in creating new specialty-specific Milestones and tailoring information on the Harmonized Milestones to pediatric pulmonologists, with the goal of improving the Milestones' utility for stakeholders, including pulmonology fellows, faculty, program directors, and accrediting bodies. In addition, we created a supplemental guide to better link the Milestones to pulmonary-specific scenarios to create a shared mental model between stakeholders and remove a potential detriment to validity. Through the process, a number of guiding principles were clarified, including: 1) every Milestone should be able to be assessed independently, without overlap with other Milestones; 2) there should be clear developmental progression from one Milestone to the next; 3) Milestones should be based on the unique skills expected of pediatric pulmonologists; and 4) health equity should be a core component to highlight as a top priority to all stakeholders. In this Perspective, we describe these principles that guided formulation of the Pediatric Pulmonary Milestones to help familiarize the pediatric pulmonary community with the new Milestones. In addition, we share lessons learned and challenges in our process to inform other specialties that may soon participate in this process.

Novel treatment of endobronchial inflammatory myofibroblastic tumor in a child.

Isolated endobronchial inflammatory myofibroblastic tumors (IMT) are rare, accounting for about 1% of primary endobronchial tumors in children. The mainstay of treatment for this tumor has been surgical resection. Recently, the identification of anaplastic lymphoma kinase (ALK) gene mutations in half of IMTs and promising results of treatment with ALK inhibitors in other ALK-positive tumors have opened the possibility of alternative approaches. We present a 4-year-old child with an ALK-positive endobronchial IMT, treated with endoscopic resection and neoadjuvant therapy with crizotinib, without evidence of tumor recurrence 2 years after the initial resection.

Gender, Parenting Status, and the Academic Productivity of Pediatricians During the COVID-19 Pandemic.

BACKGROUND: During the coronavirus disease 2019 pandemic, many women physicians experienced increased caregiver responsibilities, potentially leading to worsened gender inequities. METHODS: We surveyed faculty and trainees at a quaternary-care children's hospital regarding work environment, household obligations, and academic productivity to examine differential effects on productivity by gender and parenting status. We used descriptive statistics for demographics and analyzed Likert-scale responses with χ2 or Fisher's exact tests. We performed multivariable logistic regression to determine factors associated with self-reported academic productivity. We analyzed free-response comments using thematic analysis. RESULTS: The August 2021 survey was completed by 366 respondents (65% women; 46% response rate). Women were significantly more likely to report decreased academic productivity than men (66% [146/222] vs 30% [38/129], P <.001). Nearly one-half (49%) were parents with 80% utilizing childcare. Of these, 61% experienced unreliable childcare during the pandemic. Parents with unreliable childcare reported significantly decreased academic productivity compared with those with reliable childcare (76% [64/84] vs 36% [19/53], P <.001), and, among those with unreliable childcare, women disproportionally reported decreased academic productivity compared with men (88.5% [54/61] vs 43.5% [10/23], P <.001). After multivariable adjustment, women physicians with children were significantly more likely to report decreased academic productivity than men with children (adjusted odds ratio: 10.19, 95% confidence interval: 4.68-22.23). CONCLUSIONS: The coronavirus disease 2019 pandemic has differentially impacted men and women physicians, with women physician parents more likely to report decreased academic productivity than men with children. Unreliable childcare was a significant contributor to this disparity. Institutions must prioritize initiatives to improve gender equity in medicine.

Pediatric Faculty and Trainee Attitudes Toward the COVID-19 Pandemic.

OBJECTIVES: The coronavirus disease 2019 (COVID-19) pandemic is an unprecedented event in modern medicine. In this study, we evaluate pediatric faculty and trainee attitudes and perspectives related to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and their roles in the COVID-19 pandemic. METHODS: We surveyed a pediatric hospital's faculty and trainees (n = 701) in April 2020 about their concerns related to SARS-CoV-2, trust in current recommendations, and attitudes toward trainee roles. We used descriptive statistics to analyze results and compared across sex and roles using logistic regression. RESULTS: Among 320 respondents (46% response rate), 73% were concerned with personal risk of SARS-CoV-2 infection and 88% were concerned with loved ones' risk. Twenty-four percent were concerned because of personal risk factors. Nearly half expressed concerns as their family's major provider and about salary changes (48% and 46%). Seventy-nine percent were concerned about lack of personal protective equipment and 43% about redeployment. Respondents endorsed varying levels of trust in recommendations related to COVID-19. Nearly three-fourths (72%) felt trainees are essential personnel. The majority were receptive to returning to usual patient care and training as the pandemic progresses. Significant differences exist across sex and roles related to levels of concern, trust, and trainee roles. CONCLUSIONS: In this study, we assess the concerns and perspectives of pediatric faculty and trainees related to the COVID-19 pandemic. Most view trainees as essential personnel and recognize the importance of direct patient care in their training. These results can be used to inform policy changes and trainee roles as the COVID-19 pandemic progresses.

Sleep, sleep disordered breathing, and nocturnal hypoventilation in children with neuromuscular diseases.

Sleep disordered breathing (SDB) is now well recognized in children with neuromuscular diseases (NMD) and may lead to significant morbidity and increased mortality. Predisposing factors to SDB in children with NMD include reduced ventilatory responses, reduced activity of respiratory muscles during sleep and poor lung mechanics due to the underlying neuro-muscular disorder. SDB may present long before signs of respiratory failure emerge. When untreated, SDB may contribute to significant cardiovascular morbidities, neuro-cognitive deficits and premature death. One of the problems in detecting SDB in patients with NMD is the lack of correlation between lung function testing and daytime gas exchange. Polysomnography is the preferred method to evaluate for SDB in children with NMD. When the diagnosis of SDB is confirmed, treatment by non-invasive ventilation (NIV) is usually recommended. However, other modalities of mechanical ventilation do exist and may be indicated in combination with or without other supportive measures.

Sleep and Breathing the First Night After Adenotonsillectomy in Obese Children With Obstructive Sleep Apnea.

STUDY OBJECTIVES: There are few studies measuring postoperative respiratory complications in obese children with obstructive sleep apnea (OSA) undergoing adenotonsillectomy (AT). These complications are further compounded by perioperative medications. Our objective was to study obese children with OSA for their respiratory characteristics and sleep architecture on the night of AT. METHODS: This was a prospective study at a tertiary pediatric hospital between January 2009-February 2012. Twenty obese children between 8-17 years of age with OSA and adenotonsillar hypertrophy were recruited. Patients underwent baseline polysomnography (PSG) and AT with or without additional debulking procedures, followed by a second PSG on the night of surgery. Demographic and clinical variables, surgical details, perioperative anesthetics and analgesics, and PSG respiratory and sleep architecture parameters were recorded. Statistical tests included Pearson correlation coefficient for correlation between continuous variables and chi-square and Wilcoxon rank-sum tests for differences between groups. RESULTS: Baseline PSG showed OSA with mean obstructive apnea-hypopnea index (oAHI) 27.1 ± 22.9, SpO2 nadir 80.1 ± 7.9%, and sleep fragmentation-arousal index 25.5 ± 22.0. Postoperatively, 85% of patients had abnormal sleep studies similar to baseline, with postoperative oAHI 27.0 ± 34.3 (P = .204), SpO2 nadir, 82.0 ± 8.7% (P = .462), and arousal index, 24.3 ± 24.0 (P = .295). Sleep architecture was abnormal after surgery, showing a significant decrease in REM sleep (P = .003), and a corresponding increase in N2 (P = .017). CONCLUSIONS: Obese children undergoing AT for OSA are at increased risk for residual OSA on the night of surgery. Special considerations should be taken for postoperative monitoring and treatment of these children. COMMENTARY: A commentary on this article appears in this issue on page 775.

Pulmonary dysfunction and sleep apnea in morbid obesity.

The interplay between obesity and respiratory function has implications on lung functions, sleep disordered breathing and asthma. Severe obesity can restrict lung functions in childhood, but the extent of obstructive disease due to obesity in childhood is not clear. Obesity is clearly linked to the increased incidence of sleep disordered breathing in childhood. Most obese children with sleep disordered breathing have tonsillo-adenoidal hypertrophy contributing to sleep apnea. The presence of sleep apnea is a consideration in recommending bariatric surgery in the appropriate setting. Obese children with asthma tend to have more symptoms of asthma. Obese children, particularly girls, have a greater likelihood of developing asthma later in life. Further investigations of the various interactions between obesity and respiratory function are currently needed. Obesity is on the rise in US, reflected in the 3 times higher prevalence of overweight (body mass index > 95th percentile) in children 6 to 19 years of age (1). The prevalence of morbid or severe obesity, defined as a body mass index (BMI) of 40 or more in adults (2), has also increased from 2.9%, in the years 1988-1994, to 4.7% in the years 1999-2000 (3). In children, severe obesity has been defined as a BMI standard deviation score > 2.5 (4). The interactions between morbid obesity and the respiratory system have become more relevant today and can be broadly discussed in relation to lung functions and exercise capacity; sleep disordered breathing; and asthma.

The prevalence of metabolic syndrome in inner city obese African-American youth.

BACKGROUND: In children and adolescents, obesity increases the risk of metabolic syndrome (MS). OBJECTIVE: We examined the prevalence of MS among obese and morbidly obese children and adolescents referred to an obesity clinic in a university-based hospital center. DESIGN/METHODS: A total of 194 obese (BMI > 95%) children and adolescents were evaluated. Fasting glucose, insulin, lipid panel, BMI, blood pressures were obtained. Main outcome measures were prevalence of components of MS by modified National Cholesterol Education Program (NCEP or Adult Treatment Panel 111 (ATP 111), with MS defined as > or = 3 components. RESULTS: There were 113 females (58%) and 81 males (42%); mean age of the cohort was 11.9 years (range: 3.4-18.8 years). One hundred seventy four (90%) of the cohort were African-American, 14 (7%) were Hispanic and 6 (3%) were others. Mean BMI z- score was 2.5 and ranged from 1.7 to 4.8. Thirty five percent of the total cohort had MS. Among the morbidly obese patients (BMI z-score > 2.5), the prevalence of the MS increased to 44%. Impaired fasting glucose (5.8 %), impaired glucose tolerance (6.5%) and silent diabetes mellitus (2.4%) were also identified. CONCLUSIONS: One third of obese patients referred to a hospital-based obesity center had the MS and nearly half of morbidly obese children and adolescents had MS.

The Downstart Program: a hospital-based pediatric healthy lifestyle program for obese and morbidly obese minority youth.

Although obesity affects all cultures, ethnic groups and social strata, this disorder affects African Americans, Hispanics and the poor at a disproportionate rate. The Downstart Pediatric Healthy Lifestyle Program was developed to provide a multi-disciplinary behavioral modification program for inner city families in Brooklyn, New York interested in leading a healthier, more active lifestyle. The Downstart Program uses a four-pronged approach of medical evaluation, exercise, nutritional education and lifestyle modification. A psychological evaluation is performed to determine the individual's ability and readiness to participate in group activities. Baseline physical fitness, flexibility and muscle strength are measured, followed by a twice-weekly karate/martial arts/dance program, incorporating principles established by the President's Council on Exercise. Nutritional and behavioral modification aspects of the program consist of weekly education about food groups, portion control, goal setting and appropriate rewards for attaining goals. Our preliminary results indicate that the Downstart Program may be a viable intervention for weight loss. Further study is needed to improve strategies for motivating patients and means and criteria for assessing long-term effects on health and lifestyle.

Pharmacologic Treatment of Rett Syndrome With Glatiramer Acetate.

BACKGROUND: Rett syndrome (RTT) is a severe neurological disease that primarily affects females. The level of brain derived neurotropic factor (BDNF) expression directly correlates with the severity of RTT related symptoms. Because Glatiramer acetate (GA) stimulates secretion of BDNF in the brain, we conducted the study with the objective to assess its efficacy in improving gait velocity cognition, respiratory function, electroencephalographic findings, and quality of life in patients with RTT. METHODS: Phase two, open label, single center trial. INCLUSION CRITERIA: ambulatory girls with genetically confirmed RTT, 10 years or older. Pre- and post-treatment measures were compared using the non-parametric Wilcoxon signed rank sum test and paired t-tests. RESULTS: Ten patients were enrolled and completed the trial. Gait velocity improved significantly (improvement range 13%-95%, p=0.03 for both tests) and emerged as an especially valuable outcome measure with excellent test- retest reliability of the 2 trials within sessions (intraclass correlation coefficient=0.94). Memory, and the breath holding index also improved significantly (p≤0.03). Epileptiform discharges decreased in all four patients who had them at baseline. There was a trend towards improved quality of life, which did not reach statistical significance. CONCLUSIONS: This prospective open-label trial provides important preliminary information related to the efficacy of GA in improving gait velocity in female patients with RTT who are 10 years or older. The results of this trial justify the need for larger scale controlled trials of GA as well as provide a template for assessing the efficacy of other interventions in RTT.

Cognitive Effects of Adenotonsillectomy for Obstructive Sleep Apnea.

OBJECTIVE: Research reveals mixed evidence for the effects of adenotonsillectomy (AT) on cognitive tests in children with obstructive sleep apnea syndrome (OSAS). The primary aim of the study was to investigate effects of AT on cognitive test scores in the randomized Childhood Adenotonsillectomy Trial. METHODS: Children ages 5 to 9 years with OSAS without prolonged oxyhemoglobin desaturation were randomly assigned to watchful waiting with supportive care (n = 227) or early AT (eAT, n = 226). Neuropsychological tests were administered before the intervention and 7 months after the intervention. Mixed model analysis compared the groups on changes in test scores across follow-up, and regression analysis examined associations of these changes in the eAT group with changes in sleep measures. RESULTS: Mean test scores were within the average range for both groups. Scores improved significantly (P < .05) more across follow-up for the eAT group than for the watchful waiting group. These differences were found only on measures of nonverbal reasoning, fine motor skills, and selective attention and had small effects sizes (Cohen's d, 0.20-0.24). As additional evidence for AT-related effects on scores, gains in test scores for the eAT group were associated with improvements in sleep measures. CONCLUSIONS: Small and selective effects of AT were observed on cognitive tests in children with OSAS without prolonged desaturation. Relative to evidence from Childhood Adenotonsillectomy Trial for larger effects of surgery on sleep, behavior, and quality of life, AT may have limited benefits in reversing any cognitive effects of OSAS, or these benefits may require more extended follow-up to become manifest.

The Effect of Adenotonsillectomy for Childhood Sleep Apnea on Cardiometabolic Measures.

STUDY OBJECTIVES: Obstructive sleep apnea syndrome (OSAS) has been associated with cardiometabolic disease in adults. In children, this association is unclear. We evaluated the effect of early adenotonsillectomy (eAT) for treatment of OSAS on blood pressure, heart rate, lipids, glucose, insulin, and C-reactive protein. We also analyzed whether these parameters at baseline and changes at follow-up correlated with polysomnographic indices. DESIGN: Data collected at baseline and 7-mo follow-up were analyzed from a randomized controlled trial, the Childhood Adenotonsillectomy Trial (CHAT). SETTING: Clinical referral setting from multiple centers. PARTICIPANTS: There were 464 children, ages 5 to 9.9 y with OSAS without severe hypoxemia. INTERVENTIONS: Randomization to eAT or Watchful Waiting with Supportive Care (WWSC). MEASUREMENTS AND RESULTS: There was no significant change of cardiometabolic parameters over the 7-mo interval in the eAT group compared to WWSC group. However, overnight heart rate was incrementally higher in association with baseline OSAS severity (average heart rate increase of 3 beats per minute [bpm] for apnea-hypopnea index [AHI] of 2 versus 10; [standard error = 0.60]). Each 5-unit improvement in AHI and 5 mmHg improvement in peak end-tidal CO2 were estimated to reduce heart rate by 1 and 1.5 bpm, respectively. An increase in N3 sleep also was associated with small reductions in systolic blood pressure percentile. CONCLUSIONS: There is little variation in standard cardiometabolic parameters in children with obstructive sleep apnea syndrome (OSAS) but without severe hypoxemia at baseline or after intervention. Of all measures, overnight heart rate emerged as the most sensitive parameter of pediatric OSAS severity. CLINICAL TRIAL REGISTRATION: Clinicaltrials.gov (#NCT00560859).

Quality of life and obstructive sleep apnea symptoms after pediatric adenotonsillectomy.

BACKGROUND AND OBJECTIVES: Data from a randomized, controlled study of adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) were used to test the hypothesis that children undergoing surgery had greater quality of life (QoL) and symptom improvement than control subjects. The objectives were to compare changes in validated QoL and symptom measurements among children randomized to undergo adenotonsillectomy or watchful waiting; to determine whether race, weight, or baseline OSAS severity influenced changes in QoL and symptoms; and to evaluate associations between changes in QoL or symptoms and OSAS severity. METHODS: Children aged 5 to 9.9 years with OSAS (N = 453) were randomly assigned to undergo adenotonsillectomy or watchful waiting with supportive care. Polysomnography, the Pediatric Quality of Life inventory, the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire, the 18-item Obstructive Sleep Apnea QoL instrument, and the modified Epworth Sleepiness Scale were completed at baseline and 7 months. Changes in the QoL and symptom surveys were compared between arms. Effect modification according to race and obesity and associations between changes in polysomnographic measures and QoL or symptoms were examined. RESULTS: Greater improvements in most QoL and symptom severity measurements were observed in children randomized to undergo adenotonsillectomy, including the parent-completed Pediatric Quality of Life inventory (effect size [ES]: 0.37), the 18-item Obstructive Sleep Apnea QoL instrument (ES: -0.93), the modified Epworth Sleepiness Scale score (ES: -0.42), and the Sleep-Related Breathing Scale of the Pediatric Sleep Questionnaire (ES: -1.35). Effect modification was not observed by obesity or baseline severity but was noted for race in some symptom measures. Improvements in OSAS severity explained only a small portion of the observed changes. CONCLUSIONS: Adenotonsillectomy compared with watchful waiting resulted in significantly more improvements in parent-rated generic and OSAS-specific QoL measures and OSAS symptoms.

Utility of symptoms to predict treatment outcomes in obstructive sleep apnea syndrome.

BACKGROUND AND OBJECTIVES: Polysomnography defines the pathophysiology of obstructive sleep apnea syndrome (OSAS) but does not predict some important comorbidities or their response to adenotonsillectomy. We assessed whether OSAS symptoms, as reflected on the Sleep-Related Breathing Disorders Scale of the Pediatric Sleep Questionnaire (PSQ), may offer clinical predictive value. METHODS: Baseline and 7-month follow-up data were analyzed from 185 participants (aged 5-9 years with polysomnographically confirmed OSAS) in the surgical treatment arm of the multicenter Childhood Adenotonsillectomy Trial. Associations were assessed between baseline PSQ or polysomnographic data and baseline morbidity (executive dysfunction, behavior, quality of life, sleepiness) or postsurgical improvement. RESULTS: At baseline, each 1-SD increase in baseline PSQ score was associated with an adjusted odds ratio that was ∼3 to 4 times higher for behavioral morbidity, 2 times higher for reduced global quality of life, 6 times higher for reduced disease-specific quality of life, and 2 times higher for sleepiness. Higher baseline PSQ scores (greater symptom burden) also predicted postsurgical improvement in parent ratings of executive functioning, behavior, quality of life, and sleepiness. In contrast, baseline polysomnographic data did not independently predict these morbidities or their postsurgical improvement. Neither PSQ nor polysomnographic data were associated with objectively assessed executive dysfunction or improvement at follow-up. CONCLUSIONS: PSQ symptom items, in contrast to polysomnographic results, reflect subjective measures of OSAS-related impairment of behavior, quality of life, and sleepiness and predict their improvement after adenotonsillectomy. Although objective polysomnography is needed to diagnose OSAS, the symptoms obtained during an office visit can offer adjunctive insight into important comorbidities and likely surgical responses.

Growth after adenotonsillectomy for obstructive sleep apnea: an RCT.

BACKGROUND AND OBJECTIVES: Adenotonsillectomy for obstructive sleep apnea syndrome (OSAS) may lead to weight gain, which can have deleterious health effects when leading to obesity. However, previous data have been from nonrandomized uncontrolled studies, limiting inferences. This study examined the anthropometric changes over a 7-month interval in a randomized controlled trial of adenotonsillectomy for OSAS, the Childhood Adenotonsillectomy Trial. METHODS: A total of 464 children who had OSAS (average apnea/hypopnea index [AHI] 5.1/hour), aged 5 to 9.9 years, were randomized to Early Adenotonsillectomy (eAT) or Watchful Waiting and Supportive Care (WWSC). Polysomnography and anthropometry were performed at baseline and 7-month follow-up. Multivariable regression modeling was used to predict the change in weight and growth indices. RESULTS: Interval increases in the BMI z score (0.13 vs. 0.31) was observed in both the WWSC and eAT intervention arms, respectively, but were greater with eAT (P < .0001). Statistical modeling showed that BMI z score increased significantly more in association with eAT after considering the influences of baseline weight and AHI. A greater proportion of overweight children randomized to eAT compared with WWSC developed obesity over the 7-month interval (52% vs. 21%; P < .05). Race, gender, and follow-up AHI were not significantly associated with BMI z score change. CONCLUSIONS: eAT for OSAS in children results in clinically significant greater than expected weight gain, even in children overweight at baseline. The increase in adiposity in overweight children places them at further risk for OSAS and the adverse consequences of obesity. Monitoring weight, nutritional counseling, and encouragement of physical activity should be considered after eAT for OSAS.

Physiological effects of obstructive sleep apnea syndrome in childhood.

Sleep disordered breathing in children refers to a group of respiratory disorders that occur or are exacerbated during sleep. Obstructive sleep apnea syndrome (OSAS) is one of the most significant disorders in this group. OSAS can present in all age groups from early infancy to adolescent years. The cardinal feature of OSAS is limitation of inspiratory flow and volume during sleep resulting in abnormal gas exchange and/or alteration of sleep patterns. When OSAS is a chronic condition it often results in adverse physiological effects that impact on health and development. The present review discusses genesis of OSAS in children and consequent end organ injury with special emphasis on behavior and cognition, cardiovascular function, autonomic regulation, inflammation, endothelial function and metabolic syndrome.
