Abstract
PURPOSE To evaluate the effects of adenotonsillectomy on improving central sleep apnea events in children with obstructive sleep apnea (OSA). METHODS We searched four online databases for relevant articles published from inception until October 2022. We included studies that measured the number of central apnea events per sleep and central apnea-hypopnea index (CAHI) or central apnea index (CAI) scores in children with OSA before and after adenotonsillectomy. Our primary outcomes were changes in CAI scores, the number of central apnea events per sleep, and CAHI scores after surgery. Our secondary outcomes were changes in total and mixed apnea events, improvement of sleep outcomes, and differences in oxygen or carbon dioxide saturation during sleep. We performed meta-analyses by pooling the mean changes of all included studies with a 95% confidence interval using Stata 17. Subsequently, we performed subgroup analyses based on the presence of comorbidities. RESULTS We included 22 studies comprising 1287 patients. Central and total sleep apnea parameters, except for CAHI and mixed apnea index scores, showed significant improvements after surgery. In addition, all respiratory parameters and second and third stages of non-rapid eye movement sleep showed significant postsurgical improvements. Patients with comorbidities showed significant improvements only in the total apnea-hypopnea index, oxygen desaturation index, and minimal oxygen saturation. CONCLUSION Adenotonsillectomy improves central apnea events in patients with OSA but not in those with comorbidities.

Abstract
Obstructive sleep apnea (OSA) is an increasingly recognized disorder in children. Adenotonsillectomy is the primary surgical treatment for OSA in children with adenotonsillar hypertrophy (ATH). We present the case of an obese 4-year-old boy hospitalized for severe desaturation during sleep and severe ATH. Nasal steroid therapy proved ineffective with persistent symptoms. Polygraphy documented severe OSA with an apnea-hypopnea index (AHI) equal to 11. Tonsillectomy resulted in prompt symptom improvement and a substantial reduction of the AHI (2.2). In this case, tonsillectomy alone resulted effective in treating OSA, despite obesity. We concluded that the presence of obesity should not postpone/exclude surgical treatment of preschool children for whom ATH is the most important cause of OSA.

Abstract
Obstructive sleep apnea syndrome (OSAS) is one of the most common comorbidities in patients with Prader-Willi syndrome (PWS) and causes significant consequences. This observational study was conducted to investigate the progression of OSAS in pediatric patients with PWS, who had not undergone upper airway surgery, through a longitudinal follow-up of their annual polysomnography results. Annual body mass index (BMI), BMI z-score, sleep efficiency and stages, central apnea index (CAI), obstructive apnea-hypopnea index (OAHI), and oxygen saturation nadir values were longitudinally analyzed. At enrollment, of 22 patients (10 boys and 12 girls) aged 11.7 ± 3.9 years, 20 had OSAS. During the 4-year follow-up, only two patients had a spontaneous resolution of OSAS. The average BMI and BMI z-score increased gradually, but CAI and OAHI showed no significant differences. After statistical adjustment for sex, age, genotype, growth hormone use, and BMI z-score, OAHI was associated with the BMI z-score and deletion genotype. In conclusion, OSAS is common in patients with PWS, and rarely resolved spontaneously. Watchful waiting may not be the best OSAS management strategy. Weight maintenance and careful selection of surgical candidates are important for OSAS treatment in patients with PWS.

Abstract
Short sleep and obstructive apneas/hypopneas have been shown to be associated with childhood obesity. Still, few studies have compared sleep in children with obesity, without suspected sleep disordered breathing and normal weight peers by objective sleep measures and compared results with subjective parent assessment of sleep. Children with obesity aged 7-13 years (N = 44) and a matched group of normal weight children (N = 42) completed clinical polysomnography (Embla A10 Recording System). Parents scored their children's sleep on the Children's Sleep Habits Questionnaire (CSHQ). Mann-Whitney U tests were used to compare groups. There was a higher obstructive apnea/hypopnea index (AHI) (median obesity = 1.20 vs. median normal = 0.66; z = -1.33, U = 560.50, p = 0.002) and number of oxygen desaturation events per hour (median obesity = 0.7 vs. median normal = 0.2; z = -3.45, U = 402.50, p = 0.001) in the children with obesity compared to children with normal weight. The children with obesity had a significantly longer sleep duration (median obesity 8:50 h = vs. median normal = 8:32 h; z = -2.05, U = 687.00, p = 0.041), longer stage N2 sleep (median obesity = 87 min vs. median normal = 52 min; z = -2.87, U = 576.50, p = 0. 004) and shorter REM sleep (median obesity = 94 min vs. median normal = 121 min; z = 5.05, U = 1477.00, p ≤ .001). No differences were observed for time in sleep stage N1 and N3, wake time after sleep onset or the total arousal index . Further, no group differences were found on the CSHQ sleep-disordered breathing sub-scale (p = 0.399). The children with obesity demonstrated significantly more mild to moderate sleep disordered breathing than children with normal weight, although this was not corroborated by parent report.

Abstract
Obstructive sleep apnea affects a large proportion of otherwise healthy children in the context of interactions between craniofacial elements, adenotonsillar hypertrophy and other anatomical factors, and neuromuscular reflexes of the upper airway. In light of the adverse consequences of sleep apnea, it is important not only to proceed with early diagnosis but also to implement adequate treatment that is guided by the pathophysiological determinants of the disease in each child. Here, we will describe the current standard of care approaches to the treatment of pediatric obstructive sleep apnea, and will also explore novel management strategies that should enable more personalized therapy in the near future.

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
BACKGROUND Childhood obesity is an increasing problem with substantial comorbidities such as obstructive sleep apnea (OSA) and increased cardiovascular morbidity. Endothelial dysfunction is an underlying mechanism related to both obesity and OSA. RESEARCH QUESTION To investigate the effect of weight loss on endothelial function and OSA in obese children and to determine whether a change in endothelial function can be linked to an improvement in OSA. METHODS Obese children between 8 and 18 years of age were recruited while entering a 12-month inpatient weight loss program. Patients were followed at 3 study visits: baseline, after 10 months of weight loss, and 6 months after ending the program (18 months). Anthropometry and endothelial function (EndoPAT) were determined at all study visits. At baseline, sleep screening with a portable device (ApneaLink) was performed. This was repeated after 10 months if OSA was diagnosed at baseline. RESULTS At baseline, 130 children were included, of which 87 had OSA (67%). Seventy-two patients attended the follow-up visit at 10 months, and 28 patients attended the follow-up visit at 18 months. The BMI z-score decreased after 10 months (from 2.7 (1.4-3.4) to 1.7 (0.5-2.7); p < 0.001) and remained stable at 18 months. Endothelial function improved significantly after weight loss, evidenced by a shorter time to peak response (TPR) and higher reactive hyperemia index (p = 0.02 and p < 0.001), and remained improved after 18 months (p < 0.001 and p = 0.007). After 10 months of weight loss, 10 patients had residual OSA. These patients had a higher TPR at 10 months (225 (75-285)s) than those without OSA (135 (45-225)s) and patients with a normalized sleep study (105 (45-285)s; p = 0.02). Linear mixed models showed that more severe OSA was associated with a worse TPR at baseline and less improvement after weight loss. CONCLUSION Weight loss improves endothelial function in an obese pediatric population. However, even after weight loss, endothelial function improved less in the presence of OSA.

Abstract
Hypertrophy of adenotonsillar tissue is the most common cause of OSAS in otherwise healthy children, and therefore adenotonsillectomy is the first line treatment. Scientific societies recommend nocturnal follow-up PSG to assess for residual OSAS in children with preoperative evidence for moderate to severe OSAS, obesity, craniofacial anomalies that obstruct the upper airway and neurological disorders, based on the increasing trend of publications reporting residual OSAS after adenotonsillectomy. Follow-up PSG values in children with a pre-operative diagnosis of severe OSAS were analysed retrospectively, and compared to the parents' impression after ENT surgery. The study population included 41 healthy children with severe OSAS and adenotonsillar surgery. The percentage of children with normal PSG parameters (AHI <2/h) after adenotonsillectomy was 80.48%. A very good correlation was observed between the parents' perception after treatment and the follow-up PSG parameters, specifically when the parents perceived that the patient had shown «complete resolution» (no snoring or apnoea), 90.62% of the children had an AHI <2/h in the follow-up PSG, the maximum residual AHI being 2.6/h. In healthy children with no underlying pathology, the information provided by the parents on clinical progression after surgery could be useful and might enable the selection of those patients who require a follow-up study, avoiding overload in sleep units.

Abstract
OBJECTIVE This study aimed to explore the characteristics of the top 100 influential manuscripts on obstructive sleep apnea (OSA). METHODS All manuscripts in English were searched from the Thomson Reuters Web of Science database by using OSA-related terms and ranked based on citation frequency. The top 100 influential manuscripts were selected and further analyzed by author, subject, journal, year of publication, country of origin, and institution. RESULTS A total of 42,878 manuscripts were searched from the Web of Science. The top 100 influential manuscripts were published from 2005 to 2017, with a total citation frequency of 38,463 and a median citation frequency of 303 (range: from 210 to 2, 707). The American Journal of Respiratory and Critical Care Medicine published the largest number of manuscripts from the top 100 (n = 18; 5340 citations), followed by Sleep (n = 11; 3516 citations) and Chest (n = 7; 1784 citations). The most cited manuscript (Marin, J.M et al., Lancet 2005; 2707 citations) mainly analyzed long-term cardiovascular outcomes in men with OSA with/without continuous positive airway pressure. The most prevalent subject was associated diseases (n = 41), followed by treatments (n = 40). Most of the manuscripts were original articles (n = 63) based on observational clinical studies and published from American institutions (n = 60). CONCLUSIONS Our study identified the top 100 influential manuscripts on OSA and provides insights into the characteristics of the most highly cited manuscripts to improve our understanding and management of OSA.

Abstract
BACKGROUND Characteristics of obstructive sleep apnea (OSA) changes with age. Infants, toddlers and prepubertal children with OSA are usually underweight and may suffer from failure to thrive (FTT). Adenotonsillectomy (T&A) is the first line of treatment for OSA in childhood. In adults OSA is commonly associated with obesity and the metabolic syndrome. The change in body mass index (BMI) in adolescents with OSA following T&A was only sporadically studied. Thus, we peruse to examine the BMI z-score change following T&A in adolescents. METHODS Clalit Health Services is the largest health care organization in Israel with the largest patient registry (more than 50% of the population). Two hundred and forty two adolescents aged 12-18 who underwent T&A between 2006 and 2015 were identified in the Clalit registry and their characteristics including height and weight were retrieved. The BMI z-score of these adolescents at baseline (up to 3 months prior to T&A) and during the consecutive 3 years after T&A were analyzed and compared. RESULTS Changes in BMI Z-score were observed to all directions following T&A with overall small increase, not statistically significant (P = 0.26) from a median of 0.79 prior to T&A to a median of 0.835 after it. There was a minimal trend toward BMI z-score reduction in overweight children (n = 74) from 1.508 to 1.48 following T&A (p = NS), and in obese children (n = 33) from 2.288 to 2.000 (P = 0.06, 2 tailed). Interestingly thin individuals (n = 6) increased their BMI z-score following T&A from - 2.4 to - 0.59 (p = 0.046). CONCLUSIONS Adolescents show variable changes in their BMI z-score following T&A. In this aspect their BMI z-score change is closer to the change seen in adults treated for OSA and not that of young children. The changes observed show a trend toward normalization of the BMI z-score such that overweight children tend to decrease their BMI z-score while thin individuals tend to increase it.

[PMID: 33465738 DOI: 10.1016/j.sleep.2020.12.028] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 12/21/2020] [Accepted: 12/22/2020] [Indexed: 11/20/2022]
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.

Int J Pediatr Otorhinolaryngol 2020; 139:110394. [PMID: 33022556 DOI: 10.1016/j.ijporl.2020.110394] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Revised: 09/17/2020] [Accepted: 09/17/2020] [Indexed: 12/31/2022]
Abstract
OBJECTIVES Current clinical guidelines by the American Academy of Pediatrics recommends adenotonsillectomy (T&A) as the first-line treatment for pediatric OSA. However, obese children experience a decreased incidence of cure from T&A compared to non-obese children, with obesity increasing risk of residual post-operative OSA by up to 3.7-fold. In addition to obesity, increased age has also been linked to more severe baseline OSA, among other factors. In this study, we examined how age effects the post-operative outcome in obese children with OSA. METHODS A retrospective chart review was performed to assess post-operative T&A polysomnography outcomes of obese children. Inclusion criteria included patients who were 17 years old and younger, underwent T&A, were obese and had both pre- and post-operative sleep studies. The patients were split into 3 different groups based on their age: Group 1 (0-6 years old), Group 2 (7-11 years old), and Group 3 (12-17 years old). RESULTS 55 patients were included in the study: 13 in Group 1, 20 in Group 2, and 22 in Group 3. For Groups 1, 2, and 3 respectively, data averages were BMI percentile 99.20, 98.49, and 98.92 (P = 2.77); z-score 2.79, 2.36, and 2.45 (P = 0.026), tonsil size 3.17, 3.15, and 3.23 (P = 0.898), adenoid size 2.42, 2.05, and 1.77 (P = 0.015), time between the preoperative and postoperative PSG 179, 240, and 202 days (P = 0.481), and time from surgery to postoperative PSG 126, 170, and 127 days (P = 0.544). The average preoperative oAHI was 52.56, 41.23, and 43.49 (P = 0.732), post-operative oAHI was 1.94, 4.79, and 4.44 (P=.417); and change in oAHI was 50.62, 36.44, and 39.25 (P = 0.617). When comparing the age group of 0-6-year-olds to the older remaining patients, the post-operative oAHI was the only variable to show a significant difference between the two-groups with a P value of 0.038. The percentage of patients with post-operative resolution of OSA (oAHI<2), mild, moderate, and severe OSA, respectively, were 53%, 29%, 9%, and 9% for all patients, 70%, 23.1%, 7%, and 0% for group 1; 50%, 35%, 5%, and 10% for group 2; and 45%, 27%, 13%, and 13% for group 3. The percent of the patients requiring post-surgical nighttime airway support were 18%, 7%, 15%, and 26% for Groups All, 1, 2, and 3, respectively. CONCLUSION We found that despite having the highest rates of obesity and the most severe OSA, obese patients under 7 years old performed better following T&A, with greater cure rate, overall reduction of oAHI, and decreased need for post-surgical nighttime airway support.

Abstract
Treatment approaches to pediatric obstructive sleep apnea (OSA) have remarkably evolved over the last two decades. From an a priori assumption that surgical removal of enlarged upper airway lymphadenoid tissues (T&A) was curative in the vast majority of patients as the recommended first-line treatment for pediatric OSA, residual respiratory abnormalities are frequent. Children likely to manifest persistent OSA after T&A include those with severe OSA, obese or older children, those with concurrent asthma or allergic rhinitis, children with predisposing oropharyngeal or maxillomandibular factors, and patients with underlying medical conditions. Furthermore, selection anti-inflammatory therapy or orthodontic interventions may be preferable in milder cases. The treatment options for residual OSA after T&A encompass a large spectrum of approaches, which may be complementary, and clearly require multidisciplinary cooperation. Among these, continuous positive airway pressure (CPAP), combined anti-inflammatory agents, rapid maxillary expansion, and myofunctional therapy are all part of the armamentarium, albeit with currently low-grade evidence supporting their efficacy. In this context, there is urgent need for prospective evidence that will readily identify the correct candidate for a specific intervention, and thus enable some degree of scientifically based precision in the current one approach fits all model of pediatric OSA medical care.

Abstract
STUDY OBJECTIVES Adenotonsillar hypertrophy is the major cause of obstructive sleep apnea (OSA) in prepubertal children, but children without enlarged lymphoid tissues may still suffer from OSA. This study aimed to identify other potential anatomic features associated with childhood OSA. METHODS This prospective study took place between January 2010 and April 2014. Prepubertal children suspected to have OSA, aged 6 to 11 years, were recruited. They underwent anthropometric measurements, nocturnal polysomnography, tonsil size evaluation, x-ray cephalometry, and sonographic measurement of lateral parapharyngeal wall (LPW) thickness. Linear regression analyses were used to test for the association between anatomic measurements and OSA severity. Logistic regression analyses were used to identify potential anatomic markers for different cutoffs (obstructive apneahypopnea index (OAHI) ≥ 1 and ≥ 5 events/h) for OSA. RESULTS Forty-seven children with OSA (20 with moderate to severe disease) and 43 children for the control group were recruited. Sonographic measurement of LPW thickness and position of hyoid bone taken from x-ray cephalometry were risk factors associated with OSA. Linear regression analyses found that these two phenotypes were associated with OAHI. Multivariate models adjusted for age, sex, body mass index, z score, and tonsil size revealed that lower position of hyoid bone was independently associated with higher risk for OSA, whereas both lower position of hyoid bone and greater LPW thickness were associated with higher OAHI and also a higher risk for moderate to severe OSA. CONCLUSIONS Position of hyoid bone and LPW thickness are anatomical markers of childhood OSA independent of obesity and tonsil size. Screening tools may include cephalometry and sonographic measurement of LPW to allow better delineation of OSA risk.

Abstract
Tonsil and adenoid-tissue hypertrophy (AH) is the most common cause of pediatric sleep-disordered breathing (SDB), with AH possibly initiated by repeated exposure to infectious agents or allergens. Here, we evaluated IL-17A activity in adenoid tissue from children with SDB and its association with AH and pneumococcal carriage. Thirty-five children (aged 3-12 years) with SDB and receiving adenoidectomy and tonsillectomy were enrolled. During surgery, nasopharyngeal carriage was determined by bacterial culture and multiplex PCR via nasopharyngeal swab, and adenoid samples were collected. IL-17A and associated cytokine expression was evaluated by real-time PCR and western blotting. The mRNA analysis showed that IL-17A level, IL-17A:IL-10 ratio, and RAR-related orphan receptor-γt:forkhead box P3 ratio were significantly higher in adenoid tissues with AH, as were IL-17A level and IL-17A:IL-10 ratio in adenoid tissues with pneumococcal carriage. Additionally, pneumococcal carriage was more common in nasopharyngeal adenoids from patients without AH than those with AH. IL-17A was upregulated in adenoid tissues from patients with AH and with pneumococcal carriage. These results suggested that pneumococcal carriage initiates an IL-17A-mediated immune response in nasopharyngeal adenoids, which might be associated with AH in patients with SDB.

Abstract
The prevalence of obesity has risen rapidly in the United States in the past 20 years. Up to 25% of US children are obese, and obesity can be directly correlated with immediate and long-term health consequences. Pediatric obesity can harm multiple body systems and is a public health issue. This article focuses on how obesity affects a child's respiratory system, including pulmonary function, exercise intolerance, gas exchange, and airway musculature.

Abstract
BACKGROUND Obstructive sleep apnea in children is frequently due to tonsil and adenoid hypertrophy. This study aimed to investigate the relationship between ambulatory clinical parameters and sleep respiratory events in obese children. METHODS We carried out a prospective respiratory sleep study between 2013 and 2015. Nails obstruction, tonsils enlargement and palate position were subjectively measured. Italian attention deficit hyperactivity disorder (ADHD) rating scale for parents was also performed. The polygraph study was performed using a portable ambulatory device. RESULTS Forty-four obese children were consecutively recruited into this study. Mild sleep respiratory disturbance was showed in 31.8 % of patients; 18.2% previously had an adeno (tonsillectomy). In 50% of these obese children, both apnea-hypopnea index and oxygen desaturation index showed polygraph abnormal results. ADHD rating scale for parents scores were positive in 9.1% of patients. CONCLUSIONS We found a high rate of mild sleep respiratory disturbance and ADHD-like symptoms referred by parents. The respiratory disturbance was not totally cured by surgery. Finally, otorhinolaryngology variables were not able to explain mild sleep respiratory disturbance.

Abstract
RATIONALE Obstructive sleep apnea (OSA) is highly prevalent in children and is usually treated by adenotonsillectomy. Nonsurgical therapies for OSA consist primarily of antiinflammatory approaches and have gained popularity, but their efficacy remains to be critically examined. OBJECTIVES To determine the effect of montelukast on pediatric OSA. METHODS A prospective randomized double-blind controlled trial of polysomnographically diagnosed OSA in children ages 2-10 years who were treated with either oral montelukast (4 or 5 mg daily) or placebo for 16 weeks. Adherence to the medication was ascertained using automated timed pill dispensers along with weekly telephonic reminders. MEASUREMENTS AND MAIN RESULTS Ninety-two children diagnosed with OSA were approached, and 64 (69.6%) agreed to participate. Of these, 57 (89.0%) completed the 16-week trial, 28 in the montelukast group and 29 in the placebo group. Age, sex, and percentage of obesity were similar in the two groups, as were initial apnea-hypopnea index (AHI) scores. Overall, intention-to-treat analyses revealed that beneficial effects occurred in 20 children receiving montelukast (71.4%), whereas only 2 (6.9%) of the children receiving placebo showed reductions in AHI score (P < 0.001). Indeed, AHI decreased from 9.2 ± 4.1/hour total sleep time (TST) to 4.2 ± 2.8/hour TST (P < 0.0001) in montelukast-treated children, whereas in children receiving placebo, the AHI did not change (from 8.2 ± 5.0/h TST before to 8.7 ± 4.9/h TST at completion of the trial). CONCLUSIONS When compared with placebo, montelukast for 16 weeks effectively reduced the severity of obstructive sleep apnea in children 2-10 years of age. These results support a therapeutic role for leukotriene modifiers in pediatric OSA provided that long-term trials confirm current findings. Clinical trial registered with www.clinicaltrials.gov (NCT 00599534).

Abstract
OBJECTIVES Adenotonsillectomy (AT) markedly improves but does not necessarily normalize polysomnographic findings in children with adenotonsillar hypertrophy and related sleep-disordered breathing (SDB). Adenotonsillectomy efficacy should be evaluated by follow-up polysomnography (PSG), but this method may underestimate persistent respiratory effort (RE). Mandibular movement (MMas) monitoring is an innovative measurement that readily identifies RE during upper airway obstruction. We hypothesized that MMas indices would decrease in parallel of PSG indices and that children with persistent RE more reliably could be identified with MMas. METHODS Twenty-five children (3-12 years of age) with SDB were enrolled in this individual prospective-cohort study. Polysomnography was supplemented with a midsagittal movement magnetic sensor that measured MMas during each respiratory cycle before and > 3 months after AT. RESULTS Adenotonsillectomy significantly improved PSG indices, except for RE-related arousals (RERA). Mandibular movement index changes after AT significantly were correlated with corresponding decreases in sleep apnea-hypopnea index (AHI) and O2 desaturation index (ODI) (Spearman's rho = 0.978 and 0.922, respectively), whereas changes in MMas duration significantly were associated with both RERA duration (rho = 0.475, P = 0.017) and index (rho = 0.564, P = 0.003). Conditional multivariate analysis showed that both AHI and RERA significantly contributed to the variance of MMas index after AT (P = 0.0003 and 0.0005, respectively), whereas MMas duration consistently was related to the duration of RERA regardless of AT. CONCLUSION Adenotonsillectomy significantly reduced AHI. However, persistent RERA were apparent in a significant proportion of children, and this was reflected by the remaining abnormal MMas pattern. Follow-up of children after AT can be recommended and readily achieved by monitoring MMas to identify persistent RE. LEVEL OF EVIDENCE 4. Laryngoscope, 128:1230-1237, 2018.

[PMID: 27484971 DOI: 10.1136/archdischild-2015-310351] [Citation(s) in RCA: 37] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2015] [Revised: 06/14/2016] [Accepted: 07/10/2016] [Indexed: 11/03/2022]
Abstract
OBJECTIVE To evaluate the outcome of adenotonsillectomy (AT) in a cohort of children with Down syndrome (DS) and obstructive sleep apnoea (OSA). DESIGN Retrospective, cross-sectional study. SETTING Tertiary care centre. PATIENTS Children with DS and OSA, without previous upper airway (UA) surgery. INTERVENTIONS AT and full overnight polysomnography. MAIN OUTCOME RESULTS A significant improvement of the obstructive apnoea-hypopnoea index (oAHI) after AT was obtained. No differences in sleep efficiency or sleep fragmentation were found postoperatively. Almost half of the children had persistent OSA (oAHI ≥5/hour). RESULTS Data are presented as median (lower-upper quartile). Thirty-four children were included, median age 4.0 years (2.7-5.8), body mass index (BMI) z-score 0.81 (-0.46-1.76), and oAHI 11.4/hour (6.5-22.7). The majority presented with severe OSA (58.9%). AT was performed in 22 children, tonsillectomy in 10 and adenoidectomy in two. Postoperatively, a significant improvement of the oAHI was measured from 11.4/hour (6.5-22.7) to 3.6/hour (2.1-9.5) (p=0.001), with a parallel increase of the minimum oxygen saturation (p=0.008). Children with initially more severe OSA had significantly more improvement after UA surgery (p=0.001). Persistent OSA was found in 47.1% of the children. CONCLUSIONS AT results in a significant improvement of OSA in children with DS without a change in sleep efficiency or sleep stage distribution. Severe OSA was associated with a larger reduction of OSA severity. Almost half of the children had persistent OSA, which was not correlated to age, gender or BMI z-score.

Abstract
Sleep disordered breathing (SDB) in childhood is linked with significant end-organ dysfunction across various systems, particularly with cardiovascular, neurocognitive and metabolic consequences. If we understand the pathophysiology of SDB, diagnose it promptly and treat appropriately, we may be able to prevent morbidity associated with SDB and also save health resources around the world. In this article, we highlight articles on this topic published in medical journals in the past year. Prematurity, obesity and adenotonsillar hypertrophy are risk factors for sleep disordered breathinghttp://ow.ly/W47FU

Impact of sleep disordered breathing on behaviour among elementary school-aged children: a cross-sectional analysis of a large community-based sample. Eur Respir J 2016; 48:1631-1639.

Abstract
Sleep disordered breathing (SDB) in children has been associated with inattention, impulsivity and hyperactivity, but the associations between SDB severity and the type and severity of behavioural disruption are unclear.1022 children aged 5–7 years old prospectively underwent sleep studies and behavioural assessments through completion of standardised instruments. Participants were subdivided into four categorical groups based on the apnoea–hypopnoea index (AHI; measured per hour of total sleep time (hTST)), i.e. Group 1: nonsnoring and AHI <1 hTST–1; Group 2: habitual snoring and AHI <1 hTST–1; Group 3: habitual snoring and AHI 1–5 hTST–1; and Group 4: habitual snoring and AHI >5 hTST–1, followed by comparisons of behavioural functioning across the groups.All 10 behavioural variables differed significantly between Group 1 and all other groups. Post hoc comparisons indicated that Group 2 was the most impaired for most behavioural measures. Furthermore, differences between Group 2 and more severe sleep pathology conditions were rarely significant.This large community-based paediatric cohort confirms earlier findings highlighting a significant impact of SDB on behavioural regulation, with the greatest impact being already apparent among habitually snoring children. Thus, a likely low asymptote exists regarding SDB behavioural impact, such that further increases in severity do not measurably increase parent-rated difficulties with behavioural regulation relative to controls. Our findings do support the need for considering early intervention, particularly among those children manifesting a behavioural impact of SDB.

Abstract
Adenotonsillectomy (AT) is the recommended first-line treatment for pediatric obstructive sleep apnea (OSA) in children with adenotonsillar hypertrophy. It is now clearly established that AT results in improvement in the severity of OSA in most children. However, a significant number of OSA children undergoing AT exhibit residual persistent OSA post-surgery. Patients at increased risk of persistent OSA include those with severe disease at initial review, older or obese patients, children with underlying asthma or allergic rhinitis, and those who have concurrent underlying medical conditions, such as Trisomy 21, craniofacial syndromes or cerebral palsy. Here, we aim to highlight recent research findings into those who have persistent OSA disease, and suggest a practical approach to the management of these children.
