RESUMO
Background Pediatric obstructive sleep apnea (POSA) is a common sleep disorder that can cause major health problems if untreated. Parental knowledge and awareness are critical for early detection and management of POSA in children. This study sought to measure parents' and caregivers' knowledge and awareness of pediatric POSA in Jazan, Saudi Arabia, as well as to uncover sociodemographic correlates of knowledge levels. Methods This cross-sectional study was conducted in Jazan, Saudi Arabia. A structured survey was used to collect data on sociodemographic factors and knowledge of pediatric OSA. Data were examined using descriptive statistics, ANOVA, and multivariate logistic regression analysis. Results The study included 393 parents and caregivers, 36.4% of whom were in the 18-30 year age group. Most were Saudis (n=385; 98%), and 212 (53.9%) were men. Most parents (n=378; 96.2%) had limited knowledge of pediatric OSA. Significant knowledge gaps were observed in recognizing POSA symptoms, understanding its impact on children's academic performance, and their association with mental health issues. Internet and social networking sites were the most common sources of knowledge about POSA (n=131; 33.33%), followed by knowing someone with OSA (n=103; 26.21%). Parents with more than eight children had a significant association with more knowledge than those without children (adjusted OR = 10.661, 95% CI: 1.367-83.139, p = 0.024). Conclusion The study identified significant gaps in the recognition of POSA symptoms and understanding its impact on their children's academic performance and mental health. Despite their limited knowledge, parents were receptive to early intervention for POSA. The study suggests that parents with more children had better knowledge of POSA, indicating that experiential learning may contribute to their understanding. The study recommends developing and assessing targeted education and awareness programs for parents, healthcare providers, and the public to improve POSA diagnosis, care, and outcomes.
RESUMO
This report emphasizes the need for interdisciplinary collaboration in diagnosing and treating pediatric obstructive sleep apnea (OSA). OSA, affecting 1% to 4% of children, often results from adenotonsillar hypertrophy, craniofacial disorders, or obesity. While adenotonsillectomy is the primary treatment, about 75% of children, especially those with craniofacial disorders or obesity, continue to experience OSA symptoms post-surgery. To address these cases, several medical fields emphasize the necessity and demand for interdisciplinary collaboration in managing pediatric OSA. Therefore, the authors aimed to develop the Pediatric Obstructive Sleep Apnea Diagnostic Examination Form (POSADEF). This form, based on clinical experience and the literature, captures craniofacial and functional characteristics linked to pediatric OSA. A case study of an eight-year-old girl with OSA, who was unsuccessfully treated with adenotonsillectomy, underlines the importance of the diagnostic examination form. The orthodontic assessment revealed craniofacial disorders and subsequent treatment with maxillary expansion and functional appliance therapy resolved her OSA symptoms. This case demonstrates the value of POSADEF in enabling comprehensive evaluation and treatment across medical disciplines. POSADEF is designed to assist health care professionals in diagnosing craniofacial and orofacial anomalies contributing to pediatric OSA.
RESUMO
OBJECTIVE: This study aimed to investigate the impact of surgical intervention on peripheral blood T lymphocyte subsets and natural killer (NK) cell activity in pediatric patients with obstructive sleep apnea hypopnea syndrome (OSAHS). METHODS: A total of 36 OSAHS children, 32 children with tonsillar hypertrophy, and 30 healthy children were enrolled. Clinical data and polysomnography (PSG) results were collected. Peripheral blood samples were analyzed for T lymphocyte subsets, NK cells, and cytokine levels including Th1 (IFN-γ, IL-2, TNF-α), Th2 (IL-4, IL-10), and Th17 (IL-17). RESULTS: At baseline, OSAHS children exhibited lower LSaO2 levels and higher AHI values compared to healthy children. They also showed decreased percentages of CD3 + T cells, CD4 + T cells, NK cells, and elevated CD8 + T cells and CD4+/CD8 + ratio. Levels of IFN-γ, IL-2, TNF-α, IL-4, and IL-17 were significantly lower in OSAHS children. Post-surgery improvements were observed in LSaO2, AHI, and immune markers at 3 months and 6 months. Pearson's correlation analysis revealed significant associations between LSaO2, AHI, and peripheral blood immune parameters at baseline and 6 months post-surgery. CONCLUSION: Surgical intervention in pediatric OSAHS influences peripheral blood T lymphocyte subsets and NK cell activity. Early intervention and monitoring of immune function are crucial for the recovery and healthy development of affected children.
RESUMO
INTRODUCTION: COVID-19 has disproportionately affected healthcare access of certain minority groups, and thus could contribute to delay in timely evaluation and management of pediatric obstructive sleep apnea (OSA). Socioeconomic status (SES) is known to affect healthcare access in pediatric otolaryngology and may also be a risk factor for OSA and its associated co-morbidities. OBJECTIVES: Our primary objective is to determine the impact of COVID-19 on time to diagnosis (TTD) and time to treatment (TTT) of polysomnography (PSG)-proven moderate to severe pediatric OSA in different socioeconomic classes. Secondary objectives include determining the impact of racial and demographic factors on TTD and TTT. METHODS: This is a retrospective chart review of 120 children; 60 children pre-COVID (February 2018 to February 2020), and 60 children post-COVID onset (March 2020 to March 2022). This study was performed at a pediatric teaching hospital and tertiary referral center, and involved children aged 3-17 years old with outpatient PSG-proven moderate to severe OSA. Approval was obtained from our hospital's institutional review board (IRB). RESULTS: There were a total of 120 children, 60 in each group. The average age was 9.5 years old; females constituted 41.6 % of the sample. TTD increased from 53.7 days pre-covid to 103 days post-COVID onset in all children (p = 0.00), 42.5 days-151.9 days in white children (p = 0.00), 38 days-142.7 days in children with high SES (p = 0.00), 32.1 days-146.5 days in children with private insurance (p = 0.00), and 65.7 days-105.8 days in children with public insurance (p = 0.04). TTT did not change significantly. CONCLUSION: Our results show that TTD of OSA and obesity in advantaged groups were affected to a greater degree than disadvantaged groups. This suggests children of all socioeconomic groups are susceptible to healthcare disparities and the COVID-19 pandemic has uncovered the vulnerability of such populations. Policymakers should consider providing more funding and support for all children, including continued funding for those with lower SES.

OBJECTIVE: To examine the influence of economic connectedness (EC), a measure of social capital, on obstructive sleep apnea (OSA) severity and adenotonsillectomy outcomes in children. STUDY DESIGN: Retrospective study. SETTING: Single tertiary medical center. METHODS: The study population included 286 children who were referred for full-night polysomnography for OSA and underwent adenotonsillectomy. The primary outcome was the relationship between EC and the presence of severe OSA, and secondary outcomes included postoperative emergency room visits and residual OSA after adenotonsillectomy. Linear regression, Kruskal-Wallis test, Pearson's χ2 test, and multiple logistic regression were used for categorical and continuous data as appropriate. RESULTS: In this population, the median age was 9.0 (interquartile range [IQR] = 6.9-11.7) and 144 (50.3%) were male. The majority were white (176, 62.0%), black (60, 21.1%), and/or of Hispanic ethnicity (173, 60.9%). The median EC of this population was 0.64 (IQR = 0.53-0.86). Higher EC was associated with decreased odds of having severe OSA (odds ratio: 0.17, 95% confidence interval = 0.05-0.61). However, EC was not associated with either postoperative emergency room visits or residual OSA. CONCLUSION: EC was significantly associated with severe OSA (ie, apnea-hypopnea index ≥ 10) but not with postoperative emergency room visits or residual OSA after adenotonsillectomy. Further research is needed to understand the effects of various social capital measures on pediatric OSA and adenotonsillectomy outcomes.
RESUMO
Sleep-disordered breathing promotes not only unfavorable craniofacial changes in untreated pediatric patients but also neurocognitive, metabolic, cardiovascular, and even long-term social alterations. This systematic review evaluated whether children diagnosed with obstructive sleep apnea syndrome (OSAS) have different intestinal microbiota constitutions from healthy children and was based on the PRISMA guidelines (PROSPERO: CRD42022360074). A total of 1562 clinical studies published between 2019 and 2023 were selected from the PubMed/MEDLINE, Embase, Web of Science, Scopus, and Cochrane Library databases, of which five were included in the qualitative analysis, three being randomized and two prospective. The methodological quality was assessed (RoB 2.0 and ROBINS-I) and all studies showed a negative effect of intervention. Sleep deprivation and intermittent hypoxia in children with OSAS seem to trigger a cascade of inflammatory pathways that exacerbate the tissue response to the release of reactive oxygen species and the generation of oxidative stress, leading to a reduction in oxygen supply to the intestinal mucosa and the integral destruction of the intestinal barrier. More evidence-based investigations are needed to optimize the identification of possible alterations in the gut microbiota of pediatric patients, given that its composition may be influenced by the patient's sleep quality and, consequently, by OSAS, showing quantitative and qualitative alterations compared to that found in healthy individuals.

BACKGROUND: Adenotonsillectomy is often curative for pediatric obstructive sleep apnea, yet children remain at high risk of respiratory complications in the postoperative period. We sought to determine the incidence and risk factors for respiratory depression and airway obstruction, as well as clinically apparent respiratory events in the post-anesthesia care unit (PACU) in high-risk children after adenotonsillectomy. METHODS: In this prospective cohort study, we enrolled 60 high-risk children having adenotonsillectomy. Our primary outcome was respiratory depression and airway obstruction in the PACU measured using a noninvasive respiratory volume monitor (RVM) and defined by episodes of predicted minute ventilation less than 40% for at least 2 min. We measured clinically apparent respiratory events using continuous observation by trained study staff. RESULTS: The median (range) age of our sample was 4 years (1, 16) and 27 (45%) were female. Black and Hispanic race children comprised 80% (n = 48) of our cohort. Thirty-nine (65%) had at least one episode of PACU respiratory depression or airway obstruction measured using the RVM, while only 21 (35%) had clinically apparent respiratory events. Poisson regression demonstrated the following associations with an increase in episodes of respiratory depression and airway obstruction: BMI Z-score less than -1 (estimate 3.91; [95%CI 1.49-10.23]), BMI Z-score 1-2 (estimate 2.04; [1.20-3.48]), and two or more comorbidities (estimate 1.96; [1.11-3.46]). CONCLUSIONS: Respiratory volume monitoring in the immediate postoperative period after pediatric high-risk adenotonsillectomy identifies impaired ventilation more frequently than is clinically apparent.

OBJECTIVE: To compare patterns of obstruction in infants and toddlers with obstructive sleep apnea (OSA) by analyzing drug-induced sleep endoscopy (DISE) examinations. STUDY DESIGN: Retrospective chart review. SETTING: An academic tertiary care pediatric hospital at a single institution. METHODS: Children aged ≤3 years who underwent DISE with propofol titration from 2020 to 2022 were included in the study. Data extracted included age, body mass index, comorbidities, and polysomnography parameters. The sites of anatomic obstruction during DISE were recorded using a validated 10-site scoring system. RESULTS: A total of 86 children underwent DISE, including 15 infants (<1 year) and 71 toddlers (>1≤3 years). Sixty-two percent were male and 37% were female. The mean age of the infant group was 9.6 months (95% confidence interval [CI]: 7.92, 11.28 months), and the mean age of the toddler group was 2.3 years (95% CI: 2.06, 2.50 years). The mean total number of sites of obstruction was not significantly different between infants (N = 2.5) and toddlers (N = 3.2, P = .086). The most common subsite of significant obstruction in both infants and toddlers was the aryepiglottic folds (46.7% and 36.8%, respectively; P = .578). The sites of obstruction and frequency of their occurrence were not significantly different between the 2 groups. CONCLUSION: Multisite airway obstruction is common among children with OSA, especially at the epiglottis, aryepiglottic folds, and tongue base. There is no difference in sites of obstruction and their frequency between toddlers and infants.
RESUMO
BACKGROUND: The polysomnography (PSG) is the gold-standard for obstructive sleep apnea (OSA) syndrome diagnosis and assessment under positive airway pressure (PAP) therapies in children. Recently, an innovative digital medicine solution, including a mandibular jaw movement (MJM) sensor coupled with automated analysis, has been validated as an alternative to PSG for pediatric application. OBJECTIVE: This study aimed to assess the reliability of MJM automated analysis for the assessment of residual apnea/hypopnea events during sleep in children with OSA treated with noninvasive ventilation (NIV) or continuous PAP (CPAP). METHODS: In this open-label prospective non-randomized multicentric trial, we included children aged from 5 to 18 years with a diagnosis of severe OSA. The children underwent in-laboratory PSG with simultaneous MJM monitoring and at-home recording with MJM monitoring 3 months later. Agreement between PSG and MJM analysis in measuring the residual apnea-hypopnea index (AHI) was evaluated by the Bland-Altman method. The treatment effect on residual AHI was estimated for both PSG and MJM analysis. RESULTS: Fifteen (60% males) children were included with a median age of 12 years [interquartile range 8-15]. Two (17%) were ventilated with NIV and 13 (83%) with CPAP. There was a good agreement between MJM-AHI and PSG-AHI with a median bias of -0.25 (95% CI: -3.40 to +2.04) events/h. The reduction in AHI under treatment was consistently significant across the three measurement methods: in-laboratory PSG and MJM recordings in the laboratory and at home. CONCLUSION: Automated analysis of MJM is a highly reliable alternative method to assess residual events in a small population treated with PAP therapies.

Background: Pediatric obstructive sleep apnea (OSA) is a multifaceted disorder marked by recurrent upper airway obstruction during sleep, often coexisting with various medical conditions. This study, aimed to comprehensively analyze the Multifaceted Landscape of Pediatric Insights into Prevalence, Severity, and Coexisting Conditions. With a sample of 1928 participants, our study sought to determine the prevalence, severity, and associations between OSA and diverse conditions. Methods: Conducted retrospectively from February 2019 to April 2023, the study included pediatric patients. Data were collected through electronic health records, involving clinical assessments, medical histories, and diagnostic tests to establish OSA and coexisting condition diagnoses. Relationships between sleep parameters, apnea types, and severity indices were evaluated. Results: High OSA prevalence was evident across age groups, with severity peaking between 3 to 12 years. Among the participants, coexisting conditions included allergic rhinitis (59.6%), tonsillar hypertrophy (49.7%), adenoid hypertrophy (28.4%), and obesity (15.3%). Analysis revealed intriguing relationships between different sleep parameters and apnea types. Notable associations were observed between Obstructive Apnea (OA) and Central Apnea (CA), and Mixed Apnea (MA) displayed associations with both OA and CA. Hypopnea correlated directly with the Apnea-Hypopnea Index (AHI), reflecting its role in OSA severity. Conclusion: This study provides a comprehensive understanding of the intricate dynamics between pediatric OSA and coexisting conditions. The prevalence of OSA and its coexistence with various conditions underscore the need for comprehensive evaluation and management strategies. By revealing associations between different sleep parameters and apnea types, the study emphasizes the complexity of OSA diagnosis and management. These findings hold the potential to enhance clinical approaches, ultimately leading to improved care and outcomes for affected children.
RESUMO
Up to 80% of children with Down syndrome (DS) are affected by obstructive sleep apnea (OSA), and only 16% to 30% will have resolution of their OSA with adenotonsillectomy. Hypoglossal nerve stimulation is a well-established therapy for adults with OSA and was recently approved by the Food and Drug Administration for use in children with DS and residual OSA. There is robust experience with this therapy in adults that has led to well-established care pathways. However, given the challenges inherent to caring for a complex pediatric population, these pathways are not directly transferrable to children with DS.

BACKGROUND: There are different findings on heart rate variability (HRV) and pediatric obstructive sleep apnea (pOSA) by an overnight HRV or a 1-hr HRV. However, there is limited data of HRV and pOSA diagnosis by using a 24-h HRV test. This study aimed to evaluate if HRV had potential for OSA diagnosis by using a 24-h HRV test. METHODS: This was a prospective study included children age between 5 and 15 years old, presenting with snoring, underwent polysomnography and a 24-h Holter monitoring. Predictors for pOSA diagnosis were analyzed using logistic regression analysis. RESULTS: During the study period, there were 81 pediatric patients met the study criteria. Of those, 65 patients (80.25%) were diagnosed as OSA. There were three factors were independently associated with OSA: standard deviation of all normal interval (SDNN), high frequency (HF), and low frequency (LF). The adjusted odds ratios of these factors were 0.949 (95% confidence interval 0.913, 0.985), 0.786 (95% confidence interval 0.624, 0.989), and 1.356 (95% confidence interval 1.075, 1.709). CONCLUSIONS: HRV parameters including SDNN, HF, and LF were associated with pOSA diagnosis in children by using the 24-h Holter monitoring.

STUDY OBJECTIVES: Prior studies have demonstrated the efficacy of lingual tonsillectomy in treating pediatric obstructive sleep apnea. The goal of this study is to describe the postoperative outcomes following lingual tonsillectomy as a part of drug-induced sleep endoscopy-directed multilevel sleep surgery. METHODS: A retrospective review was performed for pediatric patients with obstructive sleep apnea who underwent lingual tonsillectomy as a part of drug-induced sleep endoscopy-directed sleep surgery. Data collected included age, sex assigned at birth, body mass index z-score, polysomnography results, past medical and surgical history, and postoperative outcomes. RESULTS: A total of 174 patients were included in the study with a mean age of 8.29 ± 3.49 years (range 1.89-15.62) and mean preoperative apnea-hypopnea index of 7.88 ± 13.42 (range 1.10-123.40). Complications occurred in 26 patients (14.9%) including 14 patients (8.0%) requiring emergency department visit or readmission and 12 patients (6.9%) experiencing postoperative bleeding. Asthma (P = .033) and developmental delay (P = .016) correlated with postoperative complications. For patients with preoperative and postoperative polysomnography data (n = 145; 83.3%), there was significant improvement (P < .001) in apnea-hypopnea index with a mean postoperative apnea-hypopnea index of 4.02 ± 7.81 (range 0.00-54.46). Surgical failure, defined as postoperative apnea-hypopnea index ≥ 5, was identified in 25 patients (17.2%). Surgical failure was associated with body mass index z-score > 2 (P = .025) and Trisomy 21 (P = .005). CONCLUSIONS: This study highlights the promising surgical success rate of drug-induced sleep endoscopy-directed lingual tonsillectomy in multilevel sleep surgery (82.8%) and infrequent complications including postoperative bleeding (6.9%) and readmission (2.3%).

INTRODUCTION: The Hypoglossal Nerve Stimulator (HNS) is a novel therapy that has been extensively studied in adults and more recently, it has been incorporated in children with Down Syndrome (DS) with persistent obstructive sleep apnea after adenotonsillectomy and trial of continuous positive airway pressure treatment. This systematic review article aims to examine the existing literature on HNS use in children to explore the benefits, efficacy, and parental experiences. METHODS: MEDLINE, Web of Science and EMBASE were searched to include all studies published up to March 2nd, 2023, on the topic of HNS use in pediatric population under 21 years old. RESULTS: A total of 179 studies were initially identified from which 10 articles were consistent with the inclusion criteria. Nine articles addressed outcomes after implantation of the HNS device in children with DS and 1 article explored the parental experiences. Findings were similar across studies where after implantation of HNS, there was marked improvement in polysomnographic outcomes and quality of life scores with high level of compliance. CONCLUSIONS: HNS holds promise as an effective treatment option for pediatric patients with DS and persistent OSA after AT and CPAP trials. It significantly improves sleep-disordered breathing, quality of life, and neurocognitive measures, leading to substantial and sustained benefits for these children. While the findings are encouraging, further research is needed to explore the potential of HNS in other pediatric populations without DS and to raise awareness among healthcare providers about this treatment option. Overall, HNS may offer significant long-term benefits for the overall well-being and health of pediatric patients with DS and persistent OSA.

RATIONALE: Lower respiratory tract infections (LRTI) during the first 2 years of life increase the risk of pediatric obstructive sleep apnea (OSA), but whether this risk varies by LRTI severity is unknown. METHODS: We analyzed data from 2962 children, aged 0-5 years, with early-life LRTI requiring hospitalization (severe LRTI, n = 235), treated as outpatients (mild LRTI, n = 394) and without LRTI (reference group, n = 2333) enrolled in the Boston Birth Cohort. Kaplan-Meier survival estimates and Cox proportional hazards models adjusted by pertinent covariables were used to evaluate the risk of pediatric OSA. RESULTS: Compared to children without LRTI, those with mild LRTI were at a higher risk of having OSA (hazard ratio [HR] 1.44, 95% confidence interval [CI]: 1.01-2.05), and those with severe LRTI were at the highest risk (HR 2.06, 95% CI: 1.41-3.02), independently of relevant covariables (including maternal age, race, gestational age, and type of delivery). Additional risk factors linked to a higher risk of OSA included prematurity (HR 1.34, 95% CI 1.01-1.77) and maternal obesity (HR 1.82, 95% CI 1.32-2.52). The time elapsed between LRTI and OSA diagnosis was similar in mild and severe LRTI cases, with medians of 23 and 25.5 months, respectively (p = .803). CONCLUSION: Infants with severe early-life LRTI have a higher risk of developing OSA, and surveillance strategies to identify OSA need to be particularly focused on this group. OSA monitoring should continue throughout the preschool years as it may develop months or years after the initial LRTI hospitalization.

Automatic deep-learning models used for sleep scoring in children with obstructive sleep apnea (OSA) are perceived as black boxes, limiting their implementation in clinical settings. Accordingly, we aimed to develop an accurate and interpretable deep-learning model for sleep staging in children using single-channel electroencephalogram (EEG) recordings. We used EEG signals from the Childhood Adenotonsillectomy Trial (CHAT) dataset (n = 1637) and a clinical sleep database (n = 980). Three distinct deep-learning architectures were explored to automatically classify sleep stages from a single-channel EEG data. Gradient-weighted Class Activation Mapping (Grad-CAM), an explainable artificial intelligence (XAI) algorithm, was then applied to provide an interpretation of the singular EEG patterns contributing to each predicted sleep stage. Among the tested architectures, a standard convolutional neural network (CNN) demonstrated the highest performance for automated sleep stage detection in the CHAT test set (accuracy = 86.9% and five-class kappa = 0.827). Furthermore, the CNN-based estimation of total sleep time exhibited strong agreement in the clinical dataset (intra-class correlation coefficient = 0.772). Our XAI approach using Grad-CAM effectively highlighted the EEG features associated with each sleep stage, emphasizing their influence on the CNN's decision-making process in both datasets. Grad-CAM heatmaps also allowed to identify and analyze epochs within a recording with a highly likelihood to be misclassified, revealing mixed features from different sleep stages within these epochs. Finally, Grad-CAM heatmaps unveiled novel features contributing to sleep scoring using a single EEG channel. Consequently, integrating an explainable CNN-based deep-learning model in the clinical environment could enable automatic sleep staging in pediatric sleep apnea tests.

Objectives: To examine the relationship between neighborhood-level advantage and severe obstructive sleep apnea (OSA) in children. Methods: A retrospective case-control study was conducted on 249 children who underwent adenotonsillectomy and had full-night polysomnography conducted within 6 months prior. Patients were divided into more or less socioeconomically disadvantaged groups using a validated measure, the area deprivation index (ADI). The primary outcomes were the relationship between the apnea-hypopnea index (AHI) and the presence of severe OSA, and the secondary outcome was residual moderate or greater OSA after tonsillectomy. Results: Of the 249 children included in the study, 175 (70.3%) were socially disadvantaged (ADI > 50). The median (interquartile range [IQR]) age was 9.4 (7.3-12.3) years, 129 (51.8%) were male, and the majority were White (151, 60.9%), Black (51, 20.6%), and/or of Hispanic (155, 62.5%) ethnicity. A total of 140 (56.2%) children were obese. The median (IQR) AHI was 8.9 (3.9-20.2). There was no significant difference in the median AHI or the presence of severe OSA between the more and less disadvantaged groups. Severe OSA was found to be associated with obesity (odds ratio [OR] = 3.13, 95% confidence interval [CI] = 1.83-5.34), and residual moderate or greater OSA was associated with older age (OR = 1.20, 95% CI = 1.05-1.38). Conclusions: The ADI was not significantly associated with severe OSA or residual OSA in this cohort of children. Although more neighborhood-level disadvantage may increase the risk of comorbidities associated with OSA, it was not an independent risk factor in this study. Level of Evidence: Level 4.
RESUMO
Pediatric obstructive sleep apnea (POSA) is a complex disease with multifactorial etiopathogenesis. The presence of craniofacial dysmorphisms influencing the patency of the upper airway is considered a risk factor for POSA development. The craniofacial features associated with sleep-related breathing disorders (SRBD) - craniosynostosis, retrognathia and micrognathia, midface and maxillary hypoplasia - have high heritability and, in a less severe form, could be also found in non-syndromic children suffering from POSA. As genetic factors play a role in both POSA and craniofacial dysmorphisms, we hypothesize that some genes associated with specific craniofacial features that are involved in the development of the orofacial area may be also considered candidate genes for POSA. The genetic background of POSA in children is less explored than in adults; so far, only one genome-wide association study for POSA has been conducted; however, children with craniofacial disorders were excluded from that study. In this narrative review, we discuss syndromes that are commonly associated with severe craniofacial dysmorphisms and a high prevalence of sleep-related breathing disorders (SRBD), including POSA. We also summarized information about their genetic background and based on this, proposed 30 candidate genes for POSA affecting craniofacial development that may play a role in children with syndromes, and identified seven of these genes that were previously associated with craniofacial features risky for POSA development in non-syndromic children. The evidence-based approach supports the proposition that variants of these candidate genes could lead to POSA phenotype even in these children, and, thus, should be considered in future research in the general pediatric population.

RESUMO
Background Obstructive sleep apnea (OSA) is relatively common in childhood and is characterized by repeated partial or complete blockages of the upper airway during sleep. Children affected by OSA can experience various symptoms including snoring, restless sleep, and behavioral issues such as hyperactivity, impulsivity, and aggression, which interfere with their quality of life. Additionally, OSA can result in serious conditions such as cardiovascular and metabolic diseases. This study aims to determine the level of knowledge and awareness of OSA among parents in the Jeddah region. Methodology An observational cross-sectional study was conducted to determine the level of awareness of OSA among all parents in Jeddah, Saudi Arabia. Participants were recruited through social media platforms. The online survey assessed the knowledge regarding the OSA definition, risk factors, associated symptoms, and treatment. Results A total of 462 participants were included. Only 16% of participants had a good level of knowledge of OSA, while the remaining 84% had a poor level of knowledge. The mean knowledge score was 15.39 ± 5.8, with a significant difference between occupations (P=0.039). Conclusion Our study reveals that parents in Jeddah, Saudi Arabia have a low level of knowledge about pediatric OSA, with only 16% demonstrating good knowledge and less than half recognizing the definition of OSA. This lack of knowledge could lead to delays in diagnosis and treatment, negatively impacting children's health and academic performance. Common symptoms of OSA reported by parents were restless sleep, mouth breathing, and snoring, but bedwetting and hyperactivity were poorly recognized. Adenoids, allergic sinusitis, enlarged tonsils, asthma, and obesity were identified as risk factors for OSA. Improving parental awareness of OSA through public campaigns, doctor consultations, and education programs is crucial. Further studies are needed to assess the effectiveness of these interventions.
