Abstract
INTRODUCTION Patients with Down syndrome (DS) are at risk for sleep disorder breathing (SDB) due to their abnormal craniofacial anatomy, hypotonia, and propensity for obesity. The prevalence and severity of SDB in this population vary between different cohorts due to the multifactorial nature of these patients and the different diagnostic criteria used. We aim to report the prevalence and severity of SDB in the DS population in Qatar. METHODS This study is a retrospective review of all patients with genetically confirmed DS who completed a diagnostic polysomnography (PSG) study at Sidra Medicine in Doha, Qatar, which is the only pediatric sleep center in the country, between September 2019 and July 2022. Clinical and PSG data were collected from the patients' electronic medical records. Central and obstructive events were scored according to the American Academy of Sleep Medicine (AASM) criteria. Obstructive sleep apnea (OSA) diagnosis was made based on apnea-hypopnea index (AHI) and defined as AHI >1.5 events/hour. OSA was considered mild if AHI was ≥ 1.5 but < 5, moderate if AHI was ≥ 5 but < 10, and severe if AHI was ≥ 10 events/hour. Diagnosis with central apnea was considered if the central apnea index was > 5 events/hour. Hypoventilation was considered present if end-tidal/transcutaneous carbon dioxide gas was more than 50 mmHg for more than 25% of total sleep time. Multiple regression analysis was performed to evaluate predictors of high AHI and rapid eye movement (REM)-AHI. RESULTS A total of 80 patients (49 males and 31 females) were included. Median (range) age was 7.3 years (0.9, 21). The mean (range) BMI z-score was 1.7 (-1.3, 4.3). Sixty-five patients were diagnosed with OSA, with a prevalence rate of 81%. OSA was mild in 25 (38.5%) patients, moderate in 15 (23.1%) patients, and severe in 25 (38.5%) patients. Only one patient was diagnosed with central apnea and five patients (6.9%) with alveolar hypoventilation. Multiple regression analysis showed BMI (P = 0.007) and snoring/apnea symptoms (P=0.023) to be predictive of high AHI. No correlation was found between the same variables and REM-AHI. Treatments used for OSA included anti-inflammatory medications in 37 (46%) patients, tonsillectomy/adenoidectomy in 13 (16.5%) patients, and positive airway pressure support in 10 (15%) patients. CONCLUSION Our patient population with DS had a high prevalence of OSA comparable to other reported cohorts. High BMI and symptoms of snoring are predictive of OSA.

Abstract
Introduction Obstructive sleep apnea (OSA) is a severe form of sleep-disordered breathing (SDB) that is strongly correlated with comorbidities, in which epiglottic collapse (EC) and other contributing factors are involved. Objectives To evaluate the occurrence of EC in OSA patients through drug-induced sleep endoscopy (DISE) and to determine the factors contributing to EC. Methods A retrospective study of 37 adult patients using medical history. Patients were assessed for laryngopharyngeal reflux (LPR) and lingual tonsil hypertrophy (LTH) using reflux symptom index and reflux finding score (RFS); for OSA using polysomnography, and for airway collapse through DISE. An independent t -test was performed to evaluate risk factors, including the involvement of three other airway structures. Results Most EC patients exhibited trap door epiglottic collapse (TDEC) (56.8%) or pushed epiglottic collapse (PEC) (29.7%). Lingual tonsil hypertrophy, RFS, and respiratory effort-related arousal (RERA) were associated with epiglottic subtypes. Laryngopharyngeal reflux patients confirmed by RFS (t(25) = -1.32, p = 0.197) tended to suffer PEC; LTH was significantly associated (X2(1) = 2.5, p = 0.012) with PEC (odds ratio [OR] value = 44) in grades II and III LTH patients; 11 of 16 TDEC patients had grade I LTH. Pushed epiglottic collapse was more prevalent among multilevel airway obstruction patients. A single additional collapse site was found only in TDEC patients. Conclusion Laryngopharyngeal reflux causes repetitive acid stress toward lingual tonsils causing LTH, resulting in PEC with grade II or III LTH. Trap door epiglottic collapse requires one additional structural collapse, while at least two additional collapse sites were necessary to develop PEC. Respiratory effort-related arousal values may indicate EC.

Abstract
Importance There are many features of Down syndrome that prompt referral to an otolaryngologist. As the lifetime prevalence and life expectancy of individuals with Down syndrome increase, it is increasingly likely that otolaryngologists will have the opportunity to care for patients with Down syndrome. Observations A confluence of characteristics common to Down syndrome may be associated with issues in the head and neck, from infancy through adulthood. Hearing concerns range from narrow ear canals and cerumen impactions to eustachian tube dysfunction, middle ear effusion, cochlear malformations, and conductive, sensorineural, and/or mixed hearing loss. Immune deficiency, hypertrophy of Waldeyer ring, and hypoplastic sinuses may complicate and develop into chronic rhinosinusitis. Speech delay, obstructive sleep apnea, dysphagia, and airway anomalies are also common among this patient population. Because these concerns may necessitate otolaryngologic surgery, it is vital for otolaryngologists to familiarize themselves with anesthetic concerns, including cervical spine instability, in patients with Down syndrome. Comorbid cardiac disease, hypothyroidism, and obesity may also affect these patients and otolaryngologic care. Conclusions and Relevance Individuals with Down syndrome may visit otolaryngology practices at all ages. Otolaryngologists that familiarize themselves with the head and neck manifestations that are common among patients with Down syndrome and know when to order screening tests will be able to provide comprehensive care.

RESPIRATORY MEDICINE 2023; 11:283-296.

Abstract
Unresolved obstructive sleep apnoea (OSA) after an adenotonsillectomy, henceforth referred to as persistent OSA, is increasingly recognised in children (2-18 years). Although associated with obesity, underlying medical complexity, and craniofacial disorders, persistent OSA also occurs in otherwise healthy children. Inadequate treatment of persistent OSA can lead to long-term adverse health outcomes beyond childhood. Positive airway pressure, used as a one-size-fits-all primary management strategy for persistent childhood OSA, is highly efficacious but has unacceptably low adherence rates. A pressing need exists for a broader, more effective management approach for persistent OSA in children. In this Personal View, we discuss the use and the need for evaluation of current and novel therapeutics, the role of shared decision-making models that consider patient preferences, and the importance of considering the social determinants of health in research and clinical practice. A multipronged, comprehensive approach to persistent OSA might achieve better clinical outcomes in childhood and promote health equity for all children.

Abstract
PURPOSE OF REVIEW Adenotonsillar hypertrophy is the most common pathogenetic contributor to obstructive sleep apnea syndrome (OSAS) in childhood, and adenotonsillectomy is the standard initial treatment. Here, we summarize the most recent evidence on the efficacy and complications of adenotonsillectomy and explore knowledge gaps in clinical management. RECENT FINDINGS Favorable adenotonsillectomy effects have been reported in children with very severe OSAS [apnea-hypopnea index (AHI) >20 episodes/h] and extremely severe OSAS (AHI >100 episodes/h), without postoperative mortality, need for endotracheal intubation, prolonged hospital stay or re-admission after hospital discharge. However, the risk of residual OSAS after adenotonsillectomy, which may reach 30-60%, has not been thoroughly established. Behavior, OSAS-related symptoms and quality of life improve postoperatively even in children with AHI 1-5 episodes/h. Natural history of enuresis resolution is accelerated postadenotonsillectomy and office-based systemic blood pressure is decreased in OSAS and hypertension. However, which children younger than 2 years should undergo adenotonsillectomy instead of adenoidectomy only to prevent recurrence of OSAS symptoms and revision surgery remains unclear. Adenotonsillectomy in children with Prader-Willi syndrome is frequently accompanied by postoperative residual OSAS while complications are not uncommon. SUMMARY In the last 2 years, several studies have provided evidence supporting the efficacy and safety of adenotonsillectomy as treatment intervention for otherwise healthy children with OSAS.
