Abstract
OBJECTIVE To analyze the growth trajectory of children with obesity before and after adenotonsillectomy (T&A). We hypothesize that T&A will not affect the growth trajectory but children in a multidisciplinary weight management program (MWMP) will have a healthier growth trajectory. STUDY DESIGN Retrospective review. SETTING Tertiary Children's Hospital. METHODS Body mass index (BMI) trajectories of nonsyndromic children with obesity and obstructive sleep apnea (OSA) who underwent T&A were analyzed. A linear mixed effects model was fit to the BMI expressed as a percentage of the 95th percentile (%BMIp95 ) data. Covariates included demographic variables, pre- and postoperative participation in an MWMP, baseline obesity class, and time. We explored clinically meaningful interactions. BMI slope estimates before and after surgery were calculated and compared for baseline obesity classification and postoperative MWMP visits. RESULTS A total of 177 patients, 58% male with a mean age of 9.7 years at the time of surgery, were studied. Higher baseline obesity class (II and III), time, the interaction between obesity class III and elapsed time relative to surgical date, and the interaction between obesity class III and the postsurgical period were all significantly associated with the outcome of %BMIp95 (P < .05). There was a significantly higher %BMIp95 trajectory following surgery in patients with baseline obesity class III who did not have any postoperative MWMP visits (P < .001). Preoperative obesity visits, however, were not significantly associated with postoperative growth. CONCLUSION The association between T&A and weight trajectory depends upon obesity class and participation in a MWMP. Coordinated care of children with obesity between otolaryngologists and an MWMP may improve OSA and obesity outcomes. LEVEL OF EVIDENCE The level of evidence: 3.

Abstract
Obstructive sleep apnea syndrome (OSA) is the main manifestation of sleep-disordered breathing in children. Untreated OSA can lead to a variety of complications and adverse consequences mainly due to intermittent hypoxemia. The pathogenesis of OSA is multifactorial. In children aged 2 years or older, adenoid and/or tonsil hypertrophy are the most common causes of upper airway lumen reduction; obesity becomes a major risk factor in older children and adolescents since the presence of fat in the pharyngeal soft tissue reduces the caliber of the lumen. Treatment includes surgical and non-surgical options. This narrative review summarizes the evidence available on the first-line approach in children with OSA, including clinical indications for medical therapy, its effectiveness, and possible adverse effects. Literature analysis showed that AT is the first-line treatment in most patients with adenotonsillar hypertrophy associated with OSA but medical therapy in children over 2 years old with mild OSA is a valid option. In mild OSA, a 1- to 6-month trial with intranasal steroids (INS) alone or in combination with montelukast with an appropriate follow-up can be considered. Further studies are needed to develop an algorithm that permits the selection of children with OSA who would benefit from alternatives to surgery, to define the optimal bridge therapy before surgery, to evaluate the long-term effects of INS +/- montelukast, and to compare the impact of standardized approaches for weight loss.

Abstract
Prevalence of childhood obesity is progressively increasing, reaching worldwide levels of 5.6% in girls and of 7.8% in boys. This also leads to a corresponding increase in the prevalence of obesity-associated morbidities particularly those involving obstructive sleep apnea(OSA). Obesity is an independent risk factor and regulator of OSA in children. There is a bidirectional causal relationship between OSA and obesity in children. The factors involved in the association between OSA and obesity are systemic inflammation, oxidative stress, and gut microbiota etc. However, a causal link between obesity-related inflammatory state and OSA pathogenesis still needs to be properly confirmed. The present review aimed to investigate the links between childhood obesity and OSA.

Abstract
Background Several clinical studies have demonstrated that pediatric obstructive sleep apnea (OSA) is associated with dysbiosis of airway mucosal microbiota. However, how oral and nasal microbial diversity, composition, and structure are altered in pediatric OSA has not been systemically explored. Methods 30 polysomnography-confirmed OSA patients with adenoid hypertrophy, and 30 controls who did not have adenoid hypertrophy, were enrolled. Swabs from four surface oral tissue sites (tongue base, soft palate, both palatine tonsils, and adenoid) and one nasal swab from both anterior nares were collected. The 16S ribosomal RNA (rRNA) V3-V4 region was sequenced to identify the microbial communities. Results The beta diversity and microbial profiles were significantly different between pediatric OSA patients and controls at the five upper airway sites. The abundances of Haemophilus, Fusobacterium, and Porphyromonas were higher at adenoid and tonsils sites of pediatric patients with OSA. Functional analysis revealed that the differential pathway between the pediatric OSA patients and controls involved glycerophospholipids and amino acid metabolism. Conclusions In this study, the oral and nasal microbiome of pediatric OSA patients exhibited certain differences in composition compared with the controls. However, the microbiota data could be useful as a reference for studies on the upper airway microbiome.

Abstract
INTRODUCTION This study aimed to find out the frequency of sleep-related breathing disorders (SRBD) in young orthodontic patients in Israel. SRBD is characterized by prolonged upper airway obstruction during sleep. METHODS The study group consisted of 309 children aged 6-17 years who attended the Orthodontic Clinic at Hadassah Medical Center. Parents were asked to complete a translated validated Pediatric Sleep Questionnaire. RESULTS Of the examined children, 10% were at high risk for SRBD. Boys were at higher risk for SRBD and were at high risk at a younger age than girls. Girls had a low risk of SRBD after adenotonsillectomy, whereas 50% of the boys that underwent adenotonsillectomy were at high risk for SRBD. CONCLUSIONS Our findings propose that 10% of the children aged 6-17 years, who were seeking orthodontic consultation at our medical center, were at high risk for SRBD. Boys were significantly at a higher risk for SRBD than girls and were at high risk at a younger age. It is important to screen young orthodontic patients for SRBD and to refer high-risk patients to their physicians for further evaluation and treatment.

Abstract
Aims to evaluate quality of life in paediatric SDB due to adenotonsillar hypertrophy and efficacy of treatment modalities (medical and surgical) by using OSA-18 questionnaire. Prospective study, conducted from April 2019 to June 2019, including 42 patients with clinical features suggestive of SDB due to adenotonsillar hypertrophy, in age group of 3-15 years. Nasopharyngoscopy was done to grade adenoid hypertrophy. OSA-18 QOL questionnaire was recorded in all patients and depending upon the severity of impact of QOL and grades of adenoid hypertrophy, patients were categorized into two groups. Group 1 received medical treatment and group 2 underwent adenotonsillectomy. Questionnaire was again recorded after 4 weeks. Pretreatment and post-treatment total mean and individual domain scores were compared. Paired t tests was used to evaluate results. Group 1 included 16 children with mild to moderate impact and received medical management. Pretreatment mean OSA-18 score of 70.31 was improved to 33.5. Group 2 enrolled 26 patients with severe impact, were subjected to adenotonsillectomy. Pretreatment and post-treatment mean score were 95.88 and 24.92 respectively. Both groups showed statistically significant improvement in all individual domains and total mean OSA-18 scores indicating improvement in QOL after treatment and efficacy of medical management for mild-moderate SDB and surgery for severe cases. OSA-18 questionnaire is self-administered and disease specific screening tool for early diagnosis and evaluation of QOL before and after treatment. It also helps to categorize patients for advocating appropriate treatment and to evaluate efficacy of treatment modalities.

Abstract
Aims Diagnosis of Adenotonsillar Hypertrophy (ATH), the leading cause of pediatric Obstructive Sleep Apnea (OSA), depends on physical exam via Brodsky's staging of tonsils. This study investigates the associations of ATH with patient parameters, and balances in-office tonsil hypertrophy appraisal against true organ mass. Materials and Methods A prospective cohort was formed of 103 children operated for ATH, and 31 matched controls. Demographic, clinical and tympanographic data, as well as Complete Blood Count (CBC) indices were compared. Absolute and relative to total body weight tonsil specimen mass were correlated with Brodsky's score. Results Tonsillar size indices were significantly raised in ATH patients. Elevated leukocytes (P = 0.012) and increased neutrophil percentage (P = 0.025) conveyed higher ATH risk. Subjective evaluation of tonsils graded 1 or 2 correlated significantly with absolute (P = 0.001) and relative (P = 0.006) objective measurements. Brodsky's score 3 and 4 displayed marginal significant association with relative (P = 0.050) but not with true (P = 0.989) mass. Conclusion An occult hematologic inflammatory response was detected in ATH children. Clinical estimation of severely hypertrophic tonsils should be adjusted for total body weight. Trial Registration Number: NCT03541434 (clinicaltrials.gov).

Abstract
OBJECTIVE Early diagnosis of obstructive sleep apnea (OSA) in children is important. The use of a nasal cannula as an airflow sensor during polysomnography has not been evaluated in younger children. The study aims to evaluate the use of nasal cannula in detecting respiratory events in children under three with suspected OSA during daytime nap studies. METHODS A total of 185 patients were prospectively included. Respiratory events were scored using nasal cannula alone, thermistor alone, and both methods simultaneously as the airflow sensor. Agreement and diagnostic accuracy were assessed. RESULTS One hundred and seventy-two children were finally analyzed and 110 (64.0%) presented OSA. Total sleep time with an uninterpretable signal was longer with the nasal cannula than with the thermistor (17.8% vs 1.9%; p < 0.001), and was associated with poor sensor tolerance and adenotonsillar hypertrophy. In the estimation of the apnea-hypopnea index, the nasal cannula showed lower agreement than the thermistor with the joint use of the two sensors (intraclass correlation coefficient: 0.79 vs 0.996 with thermistor). Compared with the thermistor, the nasal cannula presented lower sensitivity for detecting OSA (82.7% vs 95.5%) and a lower negative predictive value (76.5% vs 92.4%). Overall, fewer children were diagnosed with severe OSA with the nasal cannula (19.8% vs 30.8% with the thermistor, and 32.6% with both). CONCLUSIONS In children under the age of three, the ability of the nasal cannula to detect obstructive events was relatively low. Therefore, other non-invasive measurements for identifying respiratory events during sleep may be of additional value.

Abstract
STUDY OBJECTIVES To investigate the prevalence of positional obstructive sleep apnea (P-OSA) and rapid eye movement-related OSA (REM-OSA) in children with OSA and identify related factors. METHODS This was a cross-sectional study among children aged 2-12 years diagnosed with OSA using overnight polysomnography (PSG) between August 1, 2020, and July 31, 2021. Demographics, anthropometrics, PSG, and OSA-18 questionnaire data were recorded. RESULTS Data from a total of 474 children were available for analysis. Children had a median age of 4.8 (4.1, 6.4) years, 66.7% were male, and 23.2% were obese. The prevalence of P-OSA was 38.2% and that of REM-OSA was 43.0%. P-OSA was correlated with age and obstructive apnea-hypopnea index (OAHI; odds ratio [OR] = 1.172, 0.947; P = .005, < 0.001, respectively), but not sex, obesity, and adenoid and tonsil size (OR = 1.265, 0.785, 0.826, 0.989; P = .258, 0.327, 0.153, 0.905, respectively). REM-OSA was correlated with age, adenoid size, tonsil size, and OAHI (OR = 0.876, 1.320, 1.387, 1.021; P = .024, 0.040, 0.001, 0.042) but not with sex and obesity (OR = 0.910, 1.281; P = .643, 0.315). CONCLUSIONS The prevalence of P-OSA was 38.2% and that of REM-OSA was 43.0% in children with OSA. Age was correlated with both the prevalence of P-OSA and REM-OSA, with an increasing and decreasing prevalence as children grew older, respectively. The severity of OSA was significantly associated with the prevalence of both P-OSA and REM-OSA. Adenoid and tonsil size were correlated with the prevalence of REM-OSA but not P-OSA. Obesity and sex were not associated with the prevalence of P-OSA or REM-OSA. CITATION Wu Y, Zheng L, Cui G, Xu Z, Ni X. Subtypes of obstructive sleep apnea in children and related factors.

Efficacy of obstructive sleep apnea treatment by antileukotriene receptor and surgery therapy in children with adenotonsillar hypertrophy: A descriptive and cohort study. Front Neurol 2022; 13:1008310. [PMID: 36237622 PMCID: PMC9552176 DOI: 10.3389/fneur.2022.1008310] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2022] [Accepted: 09/12/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundPrevalence of obstructive sleep apnea (OSA) in children with adenotonsillar hypertrophy is high and related to the occlusion of the upper airway. The main treatments of OSA in these children is adenotonsillectomy. However, this intervention is an invasive method with a various success rate. Thus, the indications of tonsillectomy remain debatable and non-invasive treatment is still a potential choice in these patients.MethodsIt was a cross-sectional and interventional study. This study included children aged from 2 to 12 years-old who were diagnosed with OSA by respiratory polygraphy and had tonsillar hypertrophy with/without adenoid hypertrophy. All main data including age, gender, height, weight, body mass index (BMI), clinical symptoms, and medical history were recorded for analysis. Physical examination and endoscopy were done to evaluate the size of tonsillar and adenoid hypertrophy by using Brodsky and Likert classifications, respectively. The severity of OSA was done by using the classification of AHI severity for children.ResultsThere were 114 patients (2–12 years old) with a mean age of 5.5 ± 2.1 years included in the present study. The main reasons for consultations were snoring (96.7%), a pause of breathing (57.1%), an effort to breathe (36.8%), unrefreshing sleep (32%), doziness (28.2%), and hyperactivity (26.3%). There were 36% of subjects with tonsillar hypertrophy grade 1–2, 48.2% with grade 3, and 15.8% with grade 4 (Brodsky classification); among them, there were 46.5% of subjects with grades 1–2 of adenoid hypertrophy, 45.6% with grade 3, and 7.0% with grade 4 (Likert classification). The mean AHI was 12.6 ± 11.2 event/h. There was a significant correlation between the mean AHI and the level of tonsillar and adenoid hypertrophy severity (r = 0.7601 and r = 0.7903; p < 0.05 and p < 0.05, respectively). The improvement of clinical symptoms of study subjects was found in both groups treated with ALR (antileukotriene receptor) or ST (surgery therapy). The symptoms related to OSA at night including snoring, struggle to breathe, sleeping with the mouth open, and stopping breathing during sleep were significantly improved after treatment with ATR and with ST (p < 0.001 and p = 0.001, respectively). The mean AHI was significantly reduced in comparison with before treatment in study subjects treated with ALR (0.9 ± 1.0 vs. 3.9 ± 2.7 events/h; p = 0.001) or with ST (3.5 ± 1.4 vs. 23.4 ± 13.1 events/h; p < 0.001).ConclusionThe treatment of OSA due to adeno-tonsillar hypertrophy with ALR for moderate OSA or surgery for severe OSA might reduce the symptoms related to OSA at night and during the day.

Abstract
Objectives: In recent years, we have witnessed a growing interest in pediatric sleep-related breathing disorders (SRBD). Although a Pediatric Sleep Questionnaire (PSQ) exists and was found reliable in screening SRBD in children, many of the children remain underdiagnosed. The aim of the present study was to define anamnestic and clinical findings that can serve as red flags indicating the presence of SRBD in children. Methods: 227 children aged 4–12 years old were evaluated with regard to the following parameters: (i) anamnestic variables (e.g., general state of health, oral habits, bruxism, esophageal reflux, sleep continuity, snoring); (ii) clinical parameters (e.g., oral mucosa, palate, tonsils, tongue, floor of the mouth, angle classification, gingival health, caries risk) and (iii) presence of SRBD (through the PSQ). Results: Significant differences between children with and without SRBD were observed regarding continuous sleep, developmental delay, mouth breathing, and snoring. Taking medications for ADHD increased the odds of SRBD in children by over seven times, non-continuous sleep increased the odds of SRBD by six times, mouth breathing increased the odds by almost five times, and snoring increased the odds by over three times. Conclusions: Child caregivers from various fields (dentists, orthodontists, pediatric physicians, school nurses) should actively inquire about disturbed sleep, medications for ADHD, snoring, and mouth breathing among their young patients. Initial screening through a few simple questions may help raise red flags that can assist in the early detection of SRBD in children and lead to proper diagnosis and treatment.

Abstract
Obstructive sleep apnea (OSA) is characterised by recurring episodes of upper airway obstruction during sleep and the fundamental abnormality reflects the inability of the upper airway dilating muscles to withstand the negative forces generated within the upper airway during inspiration. Factors that result in narrowing of the oropharynx such as abnormal craniofacial anatomy, soft tissue accumulation in the neck, and rostral fluid shift in the recumbent position increase the collapsing forces within the airway. The counteracting forces of upper airway dilating muscles, especially the genioglossus, are negatively influenced by sleep onset, inadequacy of the genioglossus responsiveness, ventilatory instability, especially post arousal, and loop gain. OSA is frequently associated with comorbidities that include metabolic, cardiovascular, renal, pulmonary, and neuropsychiatric, and there is growing evidence of bidirectional relationships between OSA and comorbidity, especially for heart failure, metabolic syndrome, and stroke. A detailed understanding of the complex pathophysiology of OSA encourages the development of therapies targeted at pathophysiological endotypes and facilitates a move towards precision medicine as a potential alternative to continuous positive airway pressure therapy in selected patients.

Abstract
STUDY OBJECTIVES Asthma and obesity are risk factors for obstructive sleep apnea (OSA) in children but their link to OSA severity is uncertain. We aimed at determining whether asthma or obesity were associated with an increased risk of moderate/severe OSA. METHODS Children undergoing a one-night polysomnography for suspicion of OSA were retrospectively included. Univariate and multivariate analyses were conducted to assess the clinical and demographic characteristics linked to moderate/severe OSA (obstructive apnea-hypopnea index ≥ 5/h of sleep) with odds ratio (OR) and 95% confidence interval reported. RESULTS 490 children (311 (64%) boys) were included with a median [25th; 75th percentile] age of 8.7 [5.4; 12.9] years, 164 (33%) non-asthmatics non-obese, 122 (25%) obese non-asthmatics, 125 (26%) asthmatics non-obese, 79 (16%) asthmatics and obese. Moderate/severe OSA was present in 157 (32%) children (75/157 (48%) obese and 52/157 (33%) asthmatics). Independent factors associated with increased or decreased risk of moderate/severe OSA were: obesity and male sex (OR 1.82 [1.16; 2.87], P = 0.01, and 1.55 [1.02; 2.36], P = 0.04, respectively), and current asthma, age >6 years or behavioral disorders (OR 0.45 [0.29; 0.70], P < 0.001; 0.44 [0.27; 0.73], P < 0.001; and 0.55 [0.33; 0.92], P = 0.02, respectively). Abnormal resistance of the respiratory system (measured in 241 children), but not abnormal spirometry (measured in 213 children), increased the risk of moderate/severe OSA (OR 2.95 [1.46-5.96], P = 0.003). CONCLUSIONS In our cohort enriched in obese and asthmatic children, obesity was associated with higher risk of moderate/severe OSA whereas current asthma was not.

Abstract
Background Tumors of the central nervous system (CNS) are the most common solid childhood malignancy. Over the last decades, treatment developments have strongly contributed to the improved overall 5-year survival rate, which is now approaching 75%. However, children now face significant long-term morbidity with late-effects including sleep disorders that may have detrimental impact on everyday functioning and quality of life. The aims of this study were to (1) describe the symptoms that lead to polysomnographic evaluation; (2) describe the nature of sleep disorders diagnosed in survivors of childhood CNS tumor using polysomnography (PSG); and (3) explore the association between tumor location and diagnosed sleep disorder. Methods An extensive literature search following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines (PRISMA) was conducted. Inclusion criteria were children and adolescents diagnosed with a CNS tumor age <20 years having a PSG performed after end of tumor treatment. The primary outcome was sleep disorder confirmed by PSG. Results Of the 1,658 studies identified, 11 met the inclusion criteria. All the included articles were appraised for quality and included in the analysis. Analyses indicated that sleep disorders commonly occur among childhood CNS tumor survivors. Symptoms prior to referral for PSG were excessive daytime sleepiness (EDS), fatigue, irregular breathing during sleep and snoring. The most common sleep disorders diagnosed were sleep-related breathing disorders (i.e., obstructive sleep apnea) and central disorders of hypersomnolence (i.e., narcolepsy). Conclusion Our findings point to the potential benefit of systematically registering sleep disorder symptoms among CNS tumor patients together with tumor type and treatment information, so that at-risk patients can be identified early. Moreover, future rigorous and larger scale controlled observational studies that include possible modifiable confounders of sleep disorders such as fatigue and obesity are warranted.

Abstract
Obstructive sleep apnea is a highly prevalent disease across the lifespan and imposes substantial morbidities, some of which may become irreversible if the condition is not diagnosed and treated in a timely fashion. Here, we focus on the clinical and epidemiological characteristics of pediatric obstructive sleep apnea, describe some of the elements that by virtue of their presence facilitate the emergence of disrupted sleep and breathing and its downstream consequences, and also discuss the potential approaches to diagnosis in at-risk children.

Abstract
Purpose Several studies agree that an abnormal maxilla-mandible relationship correlates better as an Obstructive Sleep Apnea (OSA) predictor, rather than obesity. One of the orthodontic therapies recommended for this kind of craniofacial deformity is to advance the mandible forward with an orthodontic activator, therefore, the aim of this study is to determine if healthy children that use this appliance experience a widening of the upper airway as well as an improvement in their sleep-breathing patterns. Materials and methods 39 healthy children, 20 for activator group (10 boys and 10 girls, 4 mean age 10.9 + 0.9; BMI 16.2 + 1.4), 19 for control group (13 boys and 6 girls, mean age 5 9.8 + 1.4; BMI 17.6 + 2.1) participated in this study. They were required to submit 2 lateral cephalometric radiographs both at initial and final stages of evaluation, and finally three at- home sleep-breathing monitoring results for the activator group and one for the control group. Results After radiographic evaluation, it was found that children in the activator group experienced an increase in all measured variables. After evaluation with the sleep monitor, an improvement of sleep-breathing was found in children from the activator group (p<0.05). Conclusion The activator not only provides a harmonious occlusion and proper development of the mandible, but it also helps improve the quality of sleep-breathing through widening of the upper airway and reducing the number of disordered breathing events in children that undergo this therapy.

Abstract
OBJECTIVES To determine predictors of obstructive sleep apnea (OSA) in underweight children and to describe the demographic, clinical, and polysomnographic characteristics of an ethnically diverse population of underweight children with OSA. STUDY DESIGN Case-control study. SETTING University of Texas Southwestern Medical Center and Children's Medical Center of Dallas. METHODS Underweight children aged 2 to 18 years who underwent a polysomnogram for suspected OSA between January 2014 and December 2020 were included. Underweight was defined as body mass index <5th percentile per Centers for Disease Control and Prevention guidelines. Children with apnea-hypopnea index <1.0 served as a control group. Univariate and multiple logistic regression analysis was used to determine the predictors of OSA. Significance was set at P < .05. RESULTS An overall 124 children met inclusion criteria: mean age, 6.4 years; 50% female; 44% Hispanic, 31% African American, and 18% Caucasian. A total of 83 children had OSA (apnea-hypopnea index ≥1.0). Height was negatively correlated with OSA (odds ratio, 0.94; 95% CI, 0.88-0.99; P = .02) while allergic rhinitis (odds ratio, 2.97; 95% CI, 1.24-7.08; P = .01) and tonsillar hypertrophy (odds ratio, 3.38; 95% CI, 1.42-8.02; P = .01) were predictors for the presence of OSA. No demographic or clinical characteristics were predictors for severe OSA. CONCLUSION Underweight children with OSA, as compared with those without OSA, are more likely to have decreased height, tonsillar hypertrophy, and allergic rhinitis. There are no predictors of severe OSA in underweight children. We recommend polysomnography for the diagnosis of OSA in symptomatic underweight children with large tonsils, especially when they have a history of allergies.

Abstract
The obstructive sleep apnoea syndrome (OSAS) affects 1-4% of adolescents. It represents a transitional stage between paediatric and adult OSA and is characterized by specific symptoms. BACKGROUND: The persistence of childhood OSAS during adolescence is not frequent. Risk factors are male sex, obesity and a history of tonsillectomy or adenoidectomy. Symptoms may be misleading such as tiredness and depressive disorders. In adolescence, untreated OSAS may result in neuro-behavioural and cognitive deficits, systemic inflammation, cardiovascular and metabolic disorders. The French Society of Research and Sleep Medicine organized a meeting on OSAS in adolescents. A multidisciplinary group of specialists (pulmonologists, pediatricians, ENT and maxillo-facial surgeons, dentofacial orthopedists/orthodontists, myofunctional therapists and sleep specialists) exchanged their experience, discussed publications and drew up a consensus document on the diagnosis and polysomnographic criteria for OSAS in adolescents. They proposed a practical diagnostic guideline and follow-up for these adolescents. OUTLOOK AND CONCLUSION: A good knowledge of the particularities of this pathology by the physician will lead to an early diagnosis, propose adapted multifactorial treatments and avoid the deleterious consequences of this pathology at adult age.

Abstract
OBJECTIVES/HYPOTHESIS To reanalyze the growth trajectory and assess longitudinal changes of children undergoing adenotonsillectomy (AT) versus watchful waiting (WW) enrolled in the Childhood Adenotonsillectomy Trial (CHAT) study and to determine if an AT increases the risk of obesity in children. STUDY DESIGN Reanalysis of prospective cohort investigation. METHODS The study analyzed publicly available data from CHAT, including 3 months visit data not previously included in a prior publication. Statistical comparisons and mixed-effects modeling were done using age- and sex-specific BMI expressed as a percentage of the 95th percentile (%BMIp95). P < .05 was considered significant. RESULTS Children in the AT group, especially if underweight at baseline, had an increased rate of weight gain, with 100% of underweight children in the AT group becoming normal weight compared to 20% for WW. However, the rate of weight gain, as measured by the %BMIp95 trajectory for both AT and WW groups, was not significantly different when baseline weight status and obstructive sleep apnea (OSA) resolution were accounted for. Comparisons of %BMIp95 between treatment groups at baseline, 3- and 7-month follow-up visits also failed to identify statistically significant differences (P > .05). Overall for the entire cohort, resolution of OSA was associated with a decreased weight trajectory (P < .001). CONCLUSIONS AT compared to WW is not associated with an increased risk of excessive weight gain. Otolaryngologists should be aware of this updated analysis when discussing AT surgical outcomes with families. LEVEL OF EVIDENCE 2 Laryngoscope, 2021.

Abstract
The prevalence of obstructive sleep apnea syndrome (OSAS) is elevated in some high-risk populations. Children with sickle cell disease (SCD) are known to have many comorbidities, including OSAS. The objectives of this study were to assess the prevalence of and risk factors for OSAS among children with SCD in two major tertiary health care facilities in Jeddah, Saudi Arabia. This multicenter cross-sectional study took place in two major tertiary health care facilities-King Abdulaziz University Hospital and King Khalid National Guard Hospital, Jeddah, Saudi Arabia. Children with SCD who were admitted between January 2010 and December 2017 were enrolled. The Pediatric Sleep Questionnaire (PSQ) was used to screen for OSAS. Data were collected from 150 children with SCD aged between 2 and 18 years. Eighty-five percent of the children had sickle cell anemia (SCA) with HbSS, and the rest had sickle beta-thalassemia (HbS/ß-thalassemia). Based on the PSQ, 33 of the 150 (22%) children had OSAS (score ≥ 7). The average score on the PSQ was 3.8/22 (± 3.8). A history of adenotonsillar hypertrophy was found to be a significant risk factor in bivariate and multivariate analyses [aOR 5.5; 95% CI 1.84-16.35 (P < 0.001)]. The odds of having OSAS were ninefold higher in children who had periodic limb movements than in those who did not after adjustment [95% CI 1.75-48.03 (P < 0.001)]. OSAS is a highly prevalent disease among children with SCD. Many factors were associated with OSAS in the bivariate analysis, including nationality, education level, a history of adenotonsillar hypertrophy, and a history of periodic limb movements.

Sleep-Related Breathing Problem Trajectories Across Early Childhood and Academic Achievement-Related Performance at Age Eight. Front Psychol 2021; 12:661156.

Abstract
Background: Childhood sleep disordered breathing (SDB) has been linked to poorer academic performance; however, research has not investigated the extent improvement in SDB may alter outcomes across key academic skills. This study aimed to investigate if children's early SDB status could predict later academic outcomes, and if an improvement in SDB status across the early childhood years would coincide with better, later performance in key academic skills related to reading, numeracy, and listening comprehension. Methods: Eighty five case children with an SDB symptom score >25 (maximum 77) were matched to 85 control children (score <12) at recruitment (age 3). SDB severity (symptom history and clinical assessment) was evaluated at ages 3, 4, 6, and 8 years and performance on individually-administered academic skills assessed at age 8 (91% retention from age 3). Case children were categorized into “improved” or “not-improved” groups based on SDB trajectories over the 5 years. Contributions of SDB status and trajectory group to academic performance were determined using regression analysis adjusted for demographic variables. Results: History of SDB from age 3 predicted significantly poorer performance on some key academic skills (oral reading and listening skills) at age 8. Children whose SDB improved (45%) performed better in oral reading fluency than those whose SDB did not improve, but difficulties with specific tasks involving oral language (listening retell) remained when compared to controls. Conclusion: Findings support links between early SDB and worse academic outcomes and suggest key academic areas of concern around oral language. Findings highlight the need for child mental health professionals to be aware of children's sleep problems, particularly SDB (past and present), when assessing potential barriers to children's achievement, to assist with appropriate and timely referrals for evaluation of children's sleep difficulties and collaborative evaluation of response to intervention for sleep difficulties.

Abstract
BACKGROUND Oxidative stress plays a role in the pathogenesis of many chronic diseases. Upper airway obstruction has been identified as a risk factor for increased oxidative stress-related disorders such as obstructive sleep apnea. The effect of adenotonsillar hypertrophy, which may result in a narrowing of the upper airways, on oxidative stress can be a valuable subject of research. This study aimed to investigate the efficacy of adenotonsillectomy on oxidative stress evaluated using the thiol / disulfide balance. METHODS Thirty children who underwent adenotonsillectomy and 30 healthy controls, all aged from 3 to 18 years, were included in the study. Blood samples were taken preoperatively and 3 months postoperatively in the study group; in the control group, baseline blood samples were taken and samples were again taken 3 months later. Thiol / disulfide homeostasis items were analyzed. Antioxidant markers were native thiol, total thiol, and native / total thiol. Oxidative stress markers were disulfide, disulfide / native thiol, and disulfide / total thiol. RESULTS At the preoperative period, oxidative stress parameters of thiol / disulfide homeostasis were higher in the study group than in the control group (P < 0.05) and antioxidant activity parameters were lower than in the control group (P < 0.05). Three months postoperatively, oxidative stress parameters were lower than in the control group (P < 0.05), and antioxidant parameters were no different from those in the control group (P > 0.05). In the adenotonsillectomy group considered separately, oxidative stress markers of disulfide and disulfide / native thiol decreased (P < 0.05) and antioxidant markers of native thiol and total thiol increased in the postoperative measurements (P < 0.05). CONCLUSIONS Oxidative stress related to adenotonsillar hypertrophy decreased after adenotonsillectomy. The antioxidant parameters of the thiol homeostasis increased after adenotonsillectomy. We concluded that adenotonsillectomy operations should be planned and applied timeously to prevent the adverse effects of adenotonsillar hypertrophies on thiol homeostasis.

Abstract
Age-related (physiological) AH is an important problem in pediatric otorhinolaryngology.
Since the beginning of the 70s, there has been an increase in the proportion of children with
pharyngeal tonsil hypertrophy. Functional disorders of the oropharynx in children occupy the second
place based on their incidence (after disorders of the musculoskeletal system). In previous
years, there has been an increase in the incidence and prevalence of obstructive sleep apnea syndrome
(OSAS) among children. In most cases of pediatric OSAS, upper airway obstruction occurs
from the nasopharynx to the oropharynx, caused by upper airway stenosis. Consequences of untreated
OSAS in children can be inattention and behavioral problems, daytime sleepiness, and in
more severe cases are associated with a variety of comorbidities. The current review discusses the
links between hypertrophied adenoids, craniofacial development and OSAS in children taking into
account physiological and pathophysiological aspects as well as clinical evaluation of the problem.

Abstract
Importance Persistent obstructive sleep apnea after adenotonsillectomy is common in children with Down syndrome or obesity. Drug-induced sleep endoscopy could help to identify anatomic differences in these patients that might affect surgical decision-making. Objective To assess drug-induced sleep endoscopy findings in surgically naive children with obstructive sleep apnea with obesity or Down syndrome and compare these findings with children without obesity or Down syndrome. Design, Setting, and Participants This cross-sectional analysis of data from a prospective cohort study of patients enrolled between May 1, 2015, and December 31, 2019, was conducted at an academic tertiary care children's hospital and included a consecutive sample of surgically naive children (age 2-18 years) who underwent drug-induced sleep endoscopy at the time of adenotonsillectomy for sleep-disordered breathing. Indications for sleep endoscopy included severe sleep apnea, age older than 7 years, obesity, African American race, and Down syndrome. Exposures Drug-induced sleep endoscopy. Main Outcomes and Measures Sleep endoscopy findings were scored according to the Sleep Endoscopy Rating Scale. Ratings at 6 anatomic levels for children with obesity and those with Down syndrome were compared with controls without obesity or Down syndrome using several measures of effect size (Cohen d, Cramer V, and η2). Results A total of 317 children (158 girls [50%]; 219 [69%] White, 20 [6%] Black, and 103 [34%] Hispanic; mean [95% CI] age, 9.6 [9.2-10.0] years) were included, of whom 115 (36%) were controls without obesity or Down syndrome, 179 (56%) had obesity without Down syndrome, and 23 (7%) had Down syndrome. The mean apnea-hypopnea index was 16 (95% CI, 13-19), and the mean minimum O2 saturation was 83% (95% CI, 81%-85%). Compared with controls without obesity or Down syndrome, children with Down syndrome demonstrated greater overall obstruction (mean sleep endoscopy rating scale total score of 5.6 vs 4.8; Cohen d, 0.46), and greater tonsillar (percentage of complete obstruction: 65% vs 54%), tongue base (percentage of complete obstruction: 26% vs 12%), and arytenoid obstruction (percentage of at least partial obstruction, 35% vs 6%). Children with obesity had greater tonsillar (percentage of complete obstruction, 74% vs 54%) and less base of tongue obstruction (percentage of complete obstruction, 2% vs 12%) compared with controls. Conclusions and Relevance In this cohort study, surgically naive children with obesity with obstructive sleep apnea had predominantly tonsillar obstruction, whereas children with Down syndrome demonstrated greater obstruction of the tonsils, tongue base, and arytenoids compared with controls. Routine drug-induced sleep endoscopy should be considered in surgically naive children with Down syndrome to help inform the surgical plan.

Abstract
Improved recognition of obstructive sleep apnea (OSA) in children has led many to identify effective strategies to treat pediatric OSA. Positive airway pressure (PAP) therapy in children, which has been shown to resolve OSA, is highly contingent on adequate adherence. In pediatrics, adherence is complex, related largely to the influence of age. Consequently, reported adherence rates in children are often lower than adults. Notwithstanding, studies have identified significant risk factors, some modifiable, and several intervention strategies that may improve pediatric adherence. Close follow-up, including use of cloud-based monitoring, of children using PAP therapy may optimize adherence further.

Effect of body weight on upper airway findings and treatment outcome in children with obstructive sleep apnea. Sleep Med 2020; 79:19-28.

Abstract
OBJECTIVE/BACKGROUND Surgical interventions for obstructive sleep apnea (OSA) are less effective in obese than in normal-weight children. However, the mechanisms that underpin this relationship are not fully understood. Therefore, this study aimed to explore how body weight influences upper airway collapse and treatment outcome in children with OSA. METHODS We conducted a retrospective analysis of prospectively collected data on polysomnography, drug-induced sleep endoscopy (DISE), and treatment outcome in otherwise healthy children with OSA. Associations between body mass index (BMI) z-score and upper airway collapse during DISE were assessed using logistic regression modelling. Treatment success was defined as obstructive apnea-hypopnea index (oAHI) < 5 events/hour and cure as oAHI < 2 events/hour with obstructive apnea index < 1 event/hour. RESULTS A total of 139 children were included [median (Q1─Q3); age 4.5 (3.1─8.4) years; BMI z-score 0.3 (-0.8 to 1.4); oAHI 10.8 (6.8─18.0) events/hour]. Twenty-five of them were overweight and 21 were obese. After adjusting for age and history of upper airway surgery, BMI z-score was significantly correlated with circumferential upper airway collapse during DISE (odds ratio 1.67; 95% confidence interval 1.12─2.65; P = 0.011). Outcome of DISE-directed treatment was similar in normal-weight (success: 91.4%; cure: 78.5%), overweight (success: 88.0%; cure: 80.0%), and obese (success: 90.5%; cure: 76.5%) children. Children with circumferential collapse responded better to continuous positive airway pressure than to (adeno)tonsillectomy. CONCLUSION Increasing body weight is associated with circumferential upper airway collapse during DISE and, accordingly, may require treatment strategies other than (adeno)tonsillectomy.

Abstract
INTRODUCTION The treatment of choice for pediatric OSAHS is surgical. However, its etiopathogenesis is multifactorial and surgery does not always solve it. Therefore, other modalities of treatment are used. The main objective of this study is to shed light on the efficacy of surgery compared to other treatments. METHODS AND MATERIALS Prospective cohort study with 317 children ages 1-13 years and apnea-hypopnea index (AHI) ≥3/h with no previous treatment. The treatment was organised into 3 categories: surgical (n = 201), medical (n = 75) and observation (n = 41). Quality of life and sleep was assessed by two validated questionnaires (PSQ & Esteller et al.) The upper airway was explored, and nocturnal polysomnography (PSG) performed in every patient. After 12 ± 3 months of treatment was completed, a new PSG and questionnaires were evaluated. RESULTS The surgical group improved significantly both subjectively and objectively. Mean AHI decreased from 7.95/h to 2.57/h and T 90 (time spent with arterial oxygen saturation <90%) from 0.49 to 0. AHI of the medical group decreased only from 5.09/h to 4.9/h. Subjective parameters improved less than in the surgical group. Persistence after surgery was 31%, 50% following medical treatment, and after observation 75%. There were no differences in age and BMI between groups. Age or obesity showed no relationship with treatment success or failure. CONCLUSIONS The best results were achieved in surgically treated children. However, 31% of those operated had OSAHS persistence, which means a combination of treatments may be the most appropriate strategy.

Abstract
The concept of personalised medicine is likely to revolutionise the treatment of adult obstructive sleep apnoea as a result of recent advances in the understanding of disease heterogeneity by identifying clinical phenotypes, pathophysiological endotypes, biomarkers and treatable traits. Children with the condition show a similar level of heterogeneity and paediatric obstructive sleep apnoea would also benefit from a more targeted approach to diagnosis and management. This review aims to summarise the adult literature on the phenotypes and endotypes of obstructive sleep apnoea and assess whether a similar approach may also be suitable to guide the development of new diagnostic and management approaches for paediatric obstructive sleep apnoea.

Abstract
OBJECTIVE To suggest an updated interdisciplinary treatment protocol for pediatric obstructive sleep apnea (POSA) based on the integration of craniofacial growth modification into medical and surgical sleep practice. METHODS PubMed, Scopus, and Cochrane library were searched up to February 2020 using keywords. Among 184 articles, 80 studies were finally included. An integrated treatment protocol for POSA encompassing craniofacial skeletal management as well as medical and surgical care was attempted. RESULTS A differential diagnostic workflow for identifying the phenotype of POSA was suggested, and a phenotype-based treatment protocol for POSA was proposed. Despite the lack of high level of evidence, timely skeletal growth modification in three dimensions using craniofacial growth potential could be valuable treatment for upper airway development in POSA patients with craniofacial phenotypic cause. CONCLUSION A novel precision treatment protocol will advance clinicians to determine the primary option or to apply the combined strategy for POSA patients.

Abstract
Pediatric obstructive sleep apnea (OSA) is associated with adverse health outcomes; however, little is known about the diversity of this population. This retrospective study aims to investigate age-related differences in the anthropometric and clinical features of this population. A total of 253 Taiwanese children (70 (27.7%) girls and 183 (72.3%) boys) with OSA were reviewed. Their median age, body mass index (BMI) z-score, and apnea-hypopnea index were 6.9 years, 0.87, and 9.5 events/h, respectively. The cohort was divided into three subgroups: ‘preschoolers’ (≥2 and <6 years), ‘school-age children’ (≥6 and <10 years), and ‘adolescents (≥10 and <18 years)’. The percentage of the male sex, BMI z-score, neck circumference, systolic blood pressure z-score, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio tended to increase with age. Adenoid grades tended to decrease with age. Overall, disease severity was independently correlated with neck circumference, tonsil size, and adenoid grade. Increased neck circumference and tonsillar hypertrophy were the most influential factors for younger children, whereas adenoidal hypertrophy became more important at an older age. In conclusion, gender prevalence ratio, anthropometric measures, and clinical features varied with age, and the pathogenic drivers were not necessarily the same as the aggravating ones.

Abstract
Objective This study aimed to evaluate the immediate effects of mandibular posterior displacement on the pharyngeal airway space (PAS) by using cephalometric evaluations and to investigate how the surrounding structures are schematically involved. Methods In this retrospective study, 38 subjects with functional Class III malocclusion and two lateral cephalograms were selected. The first lateral cephalogram was taken with the mandible in the habitual occlusal position, and the second in anterior edge-to-edge bite. Paired t-test was used to analyze changes in the PAS, hyoid bone, tongue, and soft palate, followed by mandibular posterior displacement. Pearson's correlation analysis was used to determine the relationship between the amount of mandibular posterior displacement and other variables. Results A statistically significant decrease was observed in the PAS following mandibular posterior displacement. Along with mandibular posterior displacement, the tongue decreased in length (p < 0.001) and increased in height (p < 0.05), while the soft palate increased in length, decreased in thickness, and was posteriorly displaced (p < 0.001). The hyoid bone was also posteriorly displaced (p < 0.05). There was no correlation between the amount of mandibular posterior displacement and the measured variables. Conclusions The PAS showed a statistically significant decrease following mandibular posterior displacement, which was a consequence of retraction of the surrounding structures. However, there were individual variances between the amount of mandibular posterior displacement and the measured variables.

Abstract
BACKGROUND AND OBJECTIVE The contribution of non-anatomical factors, such as ventilatory control instability (i.e. LG), to the pathogenesis of obstructive SDB in children is unclear. Therefore, we aimed to identify the relationship between LG and severity of SDB, demographic, anthropometric and anatomical characteristics in a clinically representative cohort of children. METHODS Children (aged 3-18 years) with various severities of SDB (n = 110) and non-snoring controls (n = 36) were studied. Children were grouped according to their OAHI. Anthropometric and upper airway anatomical characteristics were measured. Spontaneous sighs were identified on polysomnography and LG, a measure of the sensitivity of the negative feedback loop that controls ventilation, was estimated by fitting a mathematical model of ventilatory control to the post-sigh ventilatory pattern. RESULTS There was no difference in LG between controls and any of the SDB severity groups. However, LG was significantly lower in children with larger tonsils (tonsil grade 4) compared with children with smaller tonsils (tonsil grade 1) (median LG (range): 0.25 (0.20-0.42) vs 0.32 (0.25-0.44); P = 0.009) and in children with a modified Mallampati score of class III/IV compared with class I (0.28 (0.24-0.33) vs 0.37 (0.27-0.44); P = 0.009). CONCLUSION A direct relationship was not found between the severity of paediatric SDB and LG. However, an altered ventilatory control sensitivity may contribute to SDB in a subgroup of children depending on their degree of anatomical compromise of the airway.

Abstract
Background The known risk factors of childhood OSAS include tonsillar and adenoidhypertrophy, obesity, craniofacial anomalies, neuromuscular disorders and African-American (AA) ancestry. Whether other factors such as allergic rhinitis (AR), premature, environmental tobacco smoking (ETS) are associated with OSAS are inconsistent in different studies. Our study enrolled children of a broad age range and included potential risk factors of OSAS derived from previous studies and our own experience. Our objective is to identify risk factors of OSAS in children in a clinical setting. Methods Children between 2 and 15 years of age exhibiting snoring symptoms who visited the sleep center for polysomnography (PSG) were enrolled. All children completed a questionnaire, physical examination and PSG. The questionnaire included demographic data and information related to potential risk factors for sleep disorders. A physical examination included measurements of height, weight, neck circumference, waist and hip ratio, visual evaluation of the tonsils and the degree of adenoid obstruction. Children with obstructive apnea-hypopnea index (OAHI) ≥ 1 were defined as OSAS. Results A total of 1578 children were enrolled and1009 children exhibited OSAS. Univariate analyses showed that snoring occurring for ≥ 3 months, male gender, preterm birth, breastfeeding, obesity, neck circumference ≥ 30 cm, waist/hip ratio ≥ 0.95, tonsillar hypertrophy, and adenoid hypertrophy were associated with OSAS. The proportion of low educational level was higher in parents who breastfed their babies than those who didn’t. Multivariate analysis showed that snoring for ≥ 3 months, male gender, obesity, breastfeeding, tonsillar hypertrophy, and adenoid hypertrophy were associated with OSAS. Confounders such as socioeconomic status, parental occupation, and health-related behaviors should be explored further to investigate the relationship between breastfeeding and OSAS. Conclusion The independent risk factors for OSAS in children included snoring ≥ 3 months, male gender, obesity, breastfeeding, tonsillar and adenoid hypertrophy. The study was registered on Clinical Trials government (NCT02447614). The name of the trial is “Follow-up Studies of Primary Snoring (PS) and Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) in Chinese Children” and the URL is https://clinicaltrials.gov/.

Abstract
BACKGROUND Positive airway pressure (PAP) has become a prominent treatment for children with sleep-disordered breathing. However, there are no large-scale studies to clarify whether PAP is well tolerated in children, and which factors are associated with better adherence to PAP therapy. In this study, we aimed to clarify adherence patterns of PAP therapy in a large paediatric population. METHODS We did a cross-sectional big-data analysis in children from Oct 1, 2014, to Aug 1, 2018, using existing data derived from PAP devices uploaded nightly in the AirView cloud database. The AirView database is a usage tracking system available to all patients who are assigned PAP therapy, which requires consent from the patient or parent or guardian. All patients older than 4 years and younger than 18 years who used continuous or automated PAP devices were evaluated. Only patients living in the USA and enrolled with a single insurance company were included. If patients were participating in an engagement programme, programme onset must have been within 7 days of therapy onset. Our primary outcome was the proportion of patients who used PAP continuously over 90 days. The primary outcome was assessed in all patients who met the age inclusion criterion and had reliable age data available. Data on missing PAP use were imputed as zero, but data on other metrics were not imputed and excluded from analysis. FINDINGS We used data recorded from Oct 1, 2014, to Aug 1, 2018. Of 40 140 children screened, 36 058 (89·8%) were US residents and 20 553 (90·1%) of them met the eligibility criteria and had accessible data (mean age 13·0 years [SD 3·7]). On the basis of 90 days of monitoring data, 12 699 (61·8%) patients continuously used PAP. Factors significantly associated with adherence included age group, residual apnoea-hypopnoea index, use and onset of patient engagement programmes, PAP pressure, and nightly median PAP mask leak, all over the 90-day study period. INTERPRETATION To our knowledge, our study represents the largest analysis of children using PAP therapy to date. The findings suggest that adherence to PAP therapy is lower than in previous reports from adults. However, numerous actionable factors were associated with improvements in adherence and should be used strategically in clinical decision making to improve PAP adherence in children. FUNDING ResMed.

Abstract
PURPOSE The relationships among PSG findings, OSA symptoms, and tonsil and adenoid size are not clear. In this study, we aimed to investigate the associations between pediatric OSA and tonsil and adenoid size using subjective (OSA-18 questionnaire) and objective (PSG) measurements. METHODS 101 consecutive patients aged from 2 to 12 years (mean age, 5.4 ± 2.2 years; boys, 72.3%) diagnosed with OSA were enrolled in two age groups (2-6 years group and 7-12 years group) and underwent PSG and lateral cephalometric radiography. Tonsil size and the adenoid-nasopharyngeal (A/N) ratio were determined. Quality of life and sleep symptoms were measured using the Chinese version OSA-18 questionnaire. Demographic and clinical data were obtained. RESULTS 75 and 26 patients were separately enrolled in 2-6 years group and 7-12 years group. In 2-6 years group, the multiple linear regression revealed that tonsil size and A/N ratio were associated with log apnea-hypopnea index (AHI), and the Spearman's rank correlation reflected a positive correlation between log AHI and the OSA-18 sleep disturbance score (r = 0.362, P = 0.001). Log OSA-18 score was correlated with tonsil size (r = 0.349, P = 0.002) but not the A/N ratio in 2-6 years group. Finally, no significant associations were observed between log OSA-18 scores and log AHI in all patients. CONCLUSION As PSG stays the golden standard for diagnoses of pediatric OSA, physical examinations and quality-of-life assessments are needed to fully assess the impact of OSA on children.

Abstract
In childhood and adolescence overweight is defined as a body mass index (BMI) above the 97th percentile for age and sex, according to the curves established by the International Obesity Task Force (IOTF). In France, it is estimated that 25 % of children under 18 years old are overweight. Overweight and obesity in this population are multifactorial, with an important influence of genetic factors, modulated by pre and post-natal (maternal smoking), societal and psychological determinants. The impact of obesity on respiratory function in children is mostly characterized by a decreased FEV1/FCV. Moreover, several studies have shown an association between asthma and overweight/obesity, with a pejorative impact of BMI on asthma control. However, asthma is still poorly characterized in this population, and the determinants of bronchial obstruction seem to differ from non-obese children, with less eosinophilic inflammation. Obstructive sleep apnea syndrome (OSAS) is a frequent complication of obesity, affecting up to 80% of obese children and adolescents. It has a specific polysomnographic definition in children. Symptoms are similar to adult OSAS, but with cognitive and neurobehavioral alterations often more important in adolescents. The treatment consists in ENT surgery when indicated (with systematic post-operative polysomnography), and nocturnal continuous positive airway pressure (CPAP). The obesity-hypoventilation syndrome (OHS) has the same definition in children as in adults and affects up to 20% of obese patients. Treatment consists in nocturnal ventilation using bilevel positive airway pressure (BiPAP). Finally, in some extreme cases, bariatric surgery can be performed. The indication should be discussed in a specialised paediatric reference centre.

Abstract
The present study aimed to evaluate the relationship between OSA and adenotonsillar size in children of different weight status. A total of 451 patients aged 2–13 years with suspected OSA were retrospectively enrolled in the study. Correlations between the apnea-hypopnea index (AHI) and adenotonsillar size in different weight status were investigated. The adenoidal/nasopharyngeal (A/N) ratio of underweight children was significantly higher than that of normal-weight children (P = 0.027). Both adenoid and tonsil size were positively correlated with logAHI in children of normal weight (r = 0.210, P = 0.001; and r = 0.212, P = 0.001) but uncorrelated in the other groups. Gender (OR = 1.49, 95% CI: 1.01–2.20, P = 0.043), obese (OR = 1.93, 95% CI: 1.10–3.40, P = 0.012), A/N ratio (OR = 1.55, 95% CI: 1.28–1.88, P < 0.001) and tonsil size (OR = 1.36, 95% CI: 1.18–1.57, P < 0.001) were all associated with the severity of OSA. Adenotonsillar hypertrophy contributed to OSA in normal-weight children. In children of abnormal weight, instead of treatment for adenotonsillar hypertrophy, appropriate treatments for other factors are required.

Abstract
OBJECTIVES To examine weight changes relative to surgical success in children with Down syndrome and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective chart review of children with Down syndrome undergoing tonsillectomy from 2005 to 2016 for OSA at a tertiary care children's hospital. Only patients with pre-and postoperative polysomnogram within 6 months of tonsillectomy were included. Demographics, weight, height, and polysomnogram data were collected. Body mass index (BMI), expressed as a percentage of the 95th percentile (%BMIp95), was calculated for 24 months prior to and following surgery. Pre-and postoperative OSA severity were also recorded. The postoperative obstructive/hypopnea index identified subjects with resolution of obstruction (obstructive/hypopnea index <2 events/hour) or persistent mild/moderate/severe obstructive apnea. Regression analyses were used to compare %BMIp95 pre- and post-tonsillectomy with %BMIp95 by OSA status following tonsillectomy. RESULTS A total of 78 patients with Down syndrome whose mean age was 5.29 years at time of tonsillectomy were identified. There was no difference between best-fit curves of %BMI p95 pre-and post-tonsillectomy. There was no difference between best-fit curves of %BMI p95 in patients who saw resolution of OSA after tonsillectomy vs patients with residual OSA. CONCLUSIONS Tonsillectomy neither alters the BMI trajectory of children with Down syndrome, nor changes differentially the risk for obesity in children whose OSA did or did not resolve after surgery.

Abstract
ObjectiveLaryngomalacia has been reported to contribute to the severity of obstructive sleep apnea (OSA) in children. It is unclear if surgical treatment of laryngomalacia improves polysomnography (PSG) outcomes in these patients. The objective of this study is to report the impact of supraglottoplasty on PSG parameters in children with laryngomalacia-related OSA.Study DesignRetrospective case series.SettingTertiary care medical center.Subjects and MethodsHistorical cohort study of consecutive children with laryngomalacia who underwent supraglottoplasty and who had undergone overnight PSG before and after surgery.ResultsForty-one patients were included in the final analysis: 22 (53.6%) were male, and 19 (46.3%) were female. The mean ± SEM age of patients at preoperative PSG was 1.3 ± 0.89 years (range, 0.003-2.9). In entire cohort, the mean obstructive apnea-hypopnea index score was reduced from 26.6 events/h before supraglottoplasty to 7.3 events/h after surgery ( P = .003). Respiratory disturbance index was reduced from 27.3 events/h before supraglottoplasty to 7.8 events/h after surgery ( P = .003). The percentage of REM sleep decreased from 30.1% ± 2.4 to 24.8% ± 1.3 ( P = .04). Sleep efficiency was improved ( P = .05).ConclusionOverall, supraglottoplasty significantly improved several PSG outcomes in children with laryngomalacia. However, mild to moderate OSA was still present postoperatively in most children. This suggested a multifactorial cause for OSA in this population.

Abstract
Background This study aimed to determine the prevalence of sleep-disordered breathing among primary school children in Riyadh, Saudi Arabia, and to evaluate associations between sleep-disordered breathing and respiratory conditions/orofacial symptoms. Methods In this cross-sectional study, 1600 questionnaires were distributed to Saudi boys and girls aged 6–12 years from 16 primary schools in Riyadh. The questionnaire covered relevant demographic and personal characteristics, presence of respiratory conditions and orofacial symptoms, and the Pediatric Sleep Questionnaire. The latter was used to assess the prevalence of symptoms of sleep-disordered breathing and was completed by the participating children’s parents. Results In total, 1350 completed questionnaires were returned (85% response rate). The children’ mean age was 9.2 ± 1.8 years; 733 (54.3%) were boys and 617 (45.7%) girls. Overall, 21% of children were at high risk of sleep-disordered breathing. The prevalence of snoring was 14.4% and that of sleep apnea 3.4%. Boys were at higher risk of sleep-disordered breathing than girls (P = 0.040). Children with respiratory conditions or orofacial symptoms were at higher risk of sleep-disordered breathing (P < 0.0001) than children without these conditions/symptoms. Conclusions Around 21% of Saudi children are at risk of sleep-disordered breathing. There is a strong association between sleep-disordered breathing symptoms and the presence of respiratory conditions or orofacial symptoms.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a markedly prevalent condition across the lifespan, particularly in overweight and obese individuals, which has been associated with an independent risk for neurocognitive, behavioral, and mood problems as well as cardiovascular and metabolic morbidities, ultimately fostering increases in overall mortality rates. In adult patients, excessive daytime sleepiness (EDS) is the most frequent symptom leading to clinical referral for evaluation and treatment, but classic EDS features are less likely to be reported in children, particularly among those with normal body-mass index. The cumulative evidence collected over the last two decades supports a conceptual framework, whereby sleep-disordered breathing in general and more particularly OSAS should be viewed as low-grade chronic inflammatory diseases. Accordingly, it is assumed that a proportion of the morbid phenotypic signature in OSAS is causally explained by underlying inflammatory processes inducing end-organ dysfunction. Here, the published links between OSAS and systemic inflammation will be critically reviewed, with special focus on the pro-inflammatory cytokines tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6), since these constitute classical prototypes of the large spectrum of inflammatory molecules that have been explored in OSAS patients.

Abstract
OBJECTIVES Different experiment approaches have demonstrated that children with obstructive sleep apnea (OSA) exhibit neurocognitive and behavioral deficits. This review summarized the potential biomarkers of OSA-associated neurocognitive impairment in children. METHODS A scoping review of studies on children with OSA that evaluated the potential value of different markers in identifying neurocognitive impairment was undertaken. Additionally, the biomarkers were categorized according to the different research methods, including brain imaging studies, serological indicators and urine markers. RESULTS Majority of the studies that evaluated blood biomarkers, plasma insulin growth factor-1 (IGF-1) and Alzheimer's disease (AD)-related biomarkers appeared to exhibit a favorable profile, and could discriminate between OSA children with or without neurocognitive impairments. Brain imaging studies and urinary neurotransmitters could also be helpful for screening OSA cognitive morbidity in children. CONCLUSION Due to limited research methods available in children, the cognitive susceptibility of children with OSA has been rarely studied. The main reason for this may be the limited research methods in children. Numerous study populations of children and complex psychological tests are required, which involve major labor and costs.Multi-center prospective studies are needed to identify suitable biomarkers for the timely prediction and effective intervention to prevent neurocognitive impairment in children with OSA and to explore further opportunities in this arena.

Abstract
OBJECTIVES For more than a century, pediatric obstructive sleep apnea (OSA) was associated with failure to thrive. However, that association has faded over the last few decades. A 21st century child with OSA is much more likely to be overweight than underweight. This raises the question: Has pediatric OSA changed over time, or has the rise of childhood obesity in the United States created a new, separate disease? This literature review explores the historical shift in the relationship between weight and OSA, and the associated changes in treatment. RESULTS We demonstrate a clear transition in the prevalence of failure to thrive and obesity in the OSA literature in the mid-2000s. What is less clear is whether these two clinical phenotypes should be considered two distinct diseases, or whether subtle differences in one set of pathophysiologic pathways-adenotonsillar hypertrophy, altered inflammation, and increased energy expenditure-can lead to divergent metabolic outcomes. More research is needed to fully elucidate the pathophysiology of OSA in children with obesity. CONCLUSIONS We may need new and different treatments for obesity-associated OSA as adenotonsillectomy-which is effective at reversing failure to thrive in OSA-is not as effective at treating OSA in children with obesity. One option is drug-induced sleep endoscopy, which could personalize and improve surgical treatment of OSA. There is some evidence that therapies used for OSA in adults (e.g., weight loss and positive airway pressure) are also helpful for overweight/obese children with OSA.
