[PMID: 38417306 DOI: 10.1016/j.sleep.2024.02.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2023] [Revised: 12/31/2023] [Accepted: 02/07/2024] [Indexed: 03/01/2024]
Abstract
OBJECTIVES Chiari type 1 malformation (CM1) may occasionally lead to central sleep apnea (CSA). We studied, in a large clinical cohort of pediatric CM1 patients, the effect of CM1 on breathing during sleep. METHODS This is a retrospective single pediatric pulmonology center study with a systematic evaluation of pediatric CM1 patients under age 18 with polysomnography (PSG) during 2008-2020. Children with syndromes were excluded. All patients had undergone head and spine magnetic resonance imaging. RESULTS We included 104 children with CM1 with a median age of 7 (interquartile range (IQR) 5-13) years. The median extent of tonsillar descent (TD) was 13 (IQR 10-18) mm. Syringomyelia was present in 19 children (18%). Of all children, 53 (51%) had normal PSG, 35 (34%) showed periodic breathing or central apnea and hypopnea index ≥5 h-1, and 16 (15%) displayed features of compensated central hypoventilation and end-tidal or transcutaneous carbon dioxide 99th percentile level above 50 mmHg. TD had the best predictive value for central breathing disorders. In a linear model, both age (61%) and TD (39%) predicted median breathing frequency (R = 0.33, p < 0.001). CONCLUSIONS Although severe CSA is a rare complication of brainstem compression in pediatric patients with CM1, short arousal-triggered episodes of periodic breathing and mild compensated central hypoventilation are common. TD shows the best but still poor prediction of the presence of a central breathing disorder. This highlights the use of PSG in patient evaluation. Posterior fossa decompression surgery effectively treats central breathing disorders.

Abstract
RATIONALE The use of long-term noninvasive respiratory support is increasing in children along with an extension of indications, in particular in children with central nervous system (CNS) disorders. OBJECTIVE The aim of this study was to describe the characteristics of children with CNS disorders treated with long-term noninvasive respiratory support in France. METHODS Data were collected from 27 French pediatric university centers through an anonymous questionnaire filled for every child treated with noninvasive ventilatory support ≥3 months on 1st June 2019. MAIN RESULTS The data of 182 patients (55% boys, median age: 10.2 [5.4;14.8] years old [range: 0.3-25]) were collected: 35 (19%) patients had nontumoral spinal cord injury, 22 (12%) CNS tumors, 63 (35%) multiple disabilities, 26 (14%) central alveolar hypoventilation and 36 (20%) other CNS disorders. Seventy five percent of the patients were treated with noninvasive ventilation (NIV) and 25% with continuous positive airway pressure (CPAP). The main investigations performed before CPAP/NIV initiation were nocturnal gas exchange recordings, alone or coupled with poly(somno)graphy (in 29% and 34% of the patients, respectively). CPAP/NIV was started in an acute setting in 10% of the patients. Median adherence was 8 [6;10] hours/night, with 12% of patients using treatment <4 h/day. Nasal mask was the most common interface (70%). Airway clearance techniques were used by 31% of patients. CONCLUSION CPAP/NIV may be a therapeutic option in children with CNS disorders. Future studies should assess treatment efficacy and patient reported outcome measures.

Abstract
BACKGROUND Chiari I malformation (CIM) is characterized by descent of the cerebellar tonsils through the foramen magnum, potentially causing symptoms from compression or obstruction of the flow of cerebrospinal fluid. Diagnosis and treatment of CIM is varied, and guidelines produced through systematic review may be helpful for clinicians. OBJECTIVE To perform a systematic review of the medical literature to answer specific questions on the diagnosis and treatment of CIM. METHODS PubMed and Embase were queried between 1946 and January 23, 2021, using the search strategies provided in Appendix I of the full guidelines. RESULTS The literature search yielded 430 abstracts, of which 79 were selected for full-text review, 44 were then rejected for not meeting the inclusion criteria or for being off-topic, and 35 were included in this systematic review. CONCLUSION Four Grade C recommendations were made based on Class III evidence, and 1 question had insufficient evidence. The full guidelines can be seen online at https://www.cns.org/guidelines/browse-guidelines-detail/2-symptoms .

Abstract
Sleep is a fundamental biological necessity, the lack of which has severe repercussions on the mental and physical well-being in individuals of all ages. The phrase "sleep-disordered breathing (SDB)" indicates a wide array of conditions characterized by snoring and/or respiratory distress due to increased upper airway resistance and pharyngeal collapsibility; these range from primary snoring to obstructive sleep apnea (OSA) and occur in all age groups. In the general pediatric population, the prevalence of OSA varies between 2% and 5%, but in some particular clinical conditions, it can be much higher. While adenotonsillar hypertrophy ("classic phenotype") is the main cause of OSA in preschool age (3-5 years), obesity ("adult phenotype") is the most common cause in adolescence. There is also a "congenital-structural" phenotype that is characterized by a high prevalence of OSA, appearing from the earliest ages of life, supported by morpho-structural abnormalities or craniofacial changes and associated with genetic syndromes such as Pierre Robin syndrome, Prader-Willi, achondroplasia, and Down syndrome. Neuromuscular disorders and lysosomal storage disorders are also frequently accompanied by a high prevalence of OSA in all life ages. Early recognition and proper treatment are crucial to avoid major neuro-cognitive, cardiovascular, and metabolic morbidities.

Abstract
OBJECTIVES Children with Chiari malformation type I (CM-I) have an increased risk of sleep apnea. The aim of the study was to describe the management of CM-I patients in relation to symptoms, magnetic resonance imaging (MRI) findings and sleep apnea syndrome (SAS). METHODS We performed a retrospective analysis of clinical charts of all 57 CM-I patients seen between September 2013 and April 2017. RESULTS A total of 45 patients had isolated CM-I or associated co-morbidity (CM-Iia), 5 had craniosynostosis (CM-Ics), and 7 a polymalformative syndrome (CM-Ipm). The prevalence of SAS, defined as an apnea-hypopnea index >1 event/h, was high in CM-I ranging from 50% to 80% according to the CM-I group. The prevalence of central sleep apnea (CSA) was low, with 5 (9%) patients having CSA and only 3 patients with CM-Iia having isolated CSA. A total of 17 patients (30%) had foramen magnum decompression (FMD). Neither positive symptoms of CM-I nor MRI findings alone, nor both combined were good indicators for FMD. No correlation was observed between the cerebellar tonsil descent and SAS in CM-I. But all 5 patients with CSA had a FMD. The combination of MRI findings and/or symptoms of CM-I together with moderate-to-severe SAS best discriminated patients who needed a FMD. CONCLUSION Our findings highlight the importance of a combined evaluation of symptoms, MRI and polygraphy results in the management of CM-I patients.

Abstract
Symptomatic progression of Chiari malformation type 1 (CM-1) can be difficult to recognize in children because of the slow progressive nature of the disorder and highly varied neurological symptoms. We present a case of an obese 11-year-old girl seeking an evaluation of snoring. Progressive social impairment and academic difficulties were also endorsed. The past medical history was remarkable for absence seizures at an earlier age with an incidental finding of CM-1 on brain imaging. No headaches, vision changes, or swallowing dysfunction were endorsed in the acute presentation. The patient underwent a polysomnogram, which revealed the unexpected finding of severe central sleep apnea. Magnetic resonance imaging of the brain revealed further herniation of the cerebellar tonsils and a cervical syrinx, which was not present on initial imaging. Posterior fossa decompression resulted in the successful resolution of symptoms. It was postulated that the social impairment and academic problems were manifestations of CM-1. There are no current standard protocols for disease surveillance of pediatric CM-1. Annual polysomnograms may serve as a useful tool. CITATION Kanney ML, Spear J, Hsu DP.

Abstract
STUDY OBJECTIVES Evaluation of elevated central apnea-hypopnea index (CAHI) or prolonged central apneas in pediatric patients typically includes neuroimaging with a focus on brainstem pathology. There is little evidence guiding thresholds of polysomnographic variables that accurately predict abnormal neuroimaging. We sought to evaluate whether additional polysomnographic variables may help predict brainstem pathology. METHODS A 10-year retrospective review of patients ages 1-18 years who received a brain magnetic resonance imaging (MRI) for an indication of central sleep apnea diagnosed via polysomnography was performed. Demographics, medical history, polysomnogram variables, and MRI results were compared. RESULTS This study included 65 patients (69.2% male). The median age was 5.8 years (interquartile range, 3.0-8.3). Most patients had negative (normal or nonsignificant) MRIs (n = 45, 69.2%); 20 (30.8%) had abnormal MRIs. Of the patients with abnormal MRIs, 13 (20.0%) had abnormalities unrelated to the brainstem. Seven patients (10.8%) were found to have brainstem pathology and had a median CAHI of 10.8 events/h (interquartile range, 6.5-21.9), and three of seven (42.9%) had hypoventilation and were more likely to have developmental delay, abnormal neurological examinations, and reflux. Other patients (n = 58) had a median CAHI of 5.6 events/h (interquartile range, 3.1-9.1), and seven (12.1%) had hypoventilation. Area under the curve and receiver operating characteristic curves showed a CAHI ≥ 9.5 events/h and ≥ 6.4% of total sleep time with end-tidal CO₂ ≥ 50 mm Hg predicted abnormal brainstem imaging. Prolonged central apneas did not predict abnormal brainstem imaging. CONCLUSIONS Most patients with central sleep apnea do not have MRIs implicating structurally abnormal brainstems. Utilizing a cutoff of CAHI of ≥ 9.5 events/h, ≥ 6.4% total sleep time with end-tidal CO₂ ≥ 50 mm Hg and/or frank hypoventilation, and additional clinical history may optimize MRI utilization in patients with central sleep apnea.

Tan HL, Kaditis AG. Phenotypic variance in pediatric obstructive sleep apnea. Pediatr Pulmonol 2021; 56:1754-1762. [PMID: 33543838 DOI: 10.1002/ppul.25309] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 01/26/2021] [Accepted: 01/27/2021] [Indexed: 01/31/2023]
Abstract
It is crucial that clinicians understand what underpins the considerable phenotypic variance in pediatric obstructive sleep apnea syndrome (OSAS), if they are to implement individually tailored phenotype-based approaches to diagnosis and management. This review summarizes the current literature on how disease severity, comorbidities, genetic and environmental/lifestyle factors interact to determine the overall OSAS phenotype. The first part discusses the impact of these factors on OSAS-related morbidity in the context of otherwise healthy children, whilst the second half details children with complex conditions, particularly focusing on the anatomical and functional abnormalities predisposing to upper airway obstruction unique to each condition. One can then understand the need for a multidimensional assessment strategy for pediatric OSAS; one that incorporates the history, physical examination, sleep study results, and biomarkers to enable precise stratification, so vital for effective determination of the timing and the nature of the therapeutic interventions required.

Validation of pediatric sleep questionnaire in children with Chiari malformation and/or spina bifida with or without myelomeningocele. Sleep Med 2021; 84:93-97. [PMID: 34134015 DOI: 10.1016/j.sleep.2021.05.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 05/21/2021] [Accepted: 05/24/2021] [Indexed: 11/17/2022]
Abstract
Sleep-disordered breathing (SDB) is common in Chiari Malformation (CM) and Spina Bifida (SB) and can lead to adverse consequences if untreated. Therefore, screening is very important but the Pediatric Sleep Questionnaire (PSQ) has not been validated in this population. Further, there is limited data on the validity of this tool in children with central nervous system malformations. Retrospective chart review of CM and SB patients evaluated in our sleep center between 2008 and 2018. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the PSQ and several of its components were calculated to predict obstructive sleep apnea (OSA). A total of 149 patients met criteria for analysis. The majority were referred to a sleep specialist due to concern for SDB. OSA was found in 36% (53/149) of all patients. The sensitivity and specificity of the PSQ to predict OSA was 73.58% and 20.83%, respectively. The PPV was 33.91%, and the NPV was 58.82%. Specificity values were higher for PSQ as negative predictors of moderate or severe OSA. In this population, the sensitivity of PSQ for OSA is reasonable but lower than values described in other populations. The specificity and NPV are low. Even with a high prevalence of OSA, symptoms of SDB may overlap with those of other comorbidities leading to a low specificity. A PSQ could be used to prioritize which patients need a PSG more urgently than others. Further studies are needed to define an optimal cut-off value of the PSQ in this population.

J Neurosurg Pediatr 2021; 27:611-619. [PMID: 33892471 DOI: 10.3171/2020.11.peds20574] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 11/09/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Chiari malformation type I (CM-I) involves the herniation of the cerebellar tonsils through the foramen magnum. CM-I is associated with both obstructive sleep apnea (OSA) and central sleep apnea (CSA) in children. The primary management of symptomatic CM-I remains surgical decompression. There is, however, a paucity of data evaluating the efficacy of decompression surgery on outcomes related to sleep-disordered breathing (SDB). The objective of this study was to evaluate SDB outcomes, specifically the need for respiratory support following decompression in pediatric patients with CM-I. METHODS This was a retrospective chart review of all children diagnosed with CM-I when younger than 18 years of age who had polysomnography (PSG) studies pre- and postsurgery, between January 2008 and October 2018 at the Hospital for Sick Children in Toronto. Patient demographics, symptoms, PSG data, ongoing respiratory support, and surgical notes were recorded. Differences in PSG studies obtained pre- and postsurgery were compared using the Wilcoxon test for paired samples. RESULTS A total of 15 children with 15 interventions met inclusion criteria with pre- and postsurgery PSG studies and were considered for statistical analysis. Of the 15 subjects included for analysis, preoperative OSA was present in 2 (13.3%), CSA in 5 (33.3%), mixed SDB (both OSA and CSA) in 4 (26.7%), and no significant SDB in 4 (26.7%). Postoperatively, OSA was present in 3 (20.0%), CSA in 4 (26.7%), mixed SDB in 0 (0%), and no significant SDB in 8 (53.3%). The presence of severe OSA decreased from 4/15 (26.7%) to 2/15 (13.3%) postoperatively, and severe CSA decreased from 5/15 (33.3%) to 2/15 (13.3%) postoperatively. Following decompression surgery, 7/15 subjects (46.7%) required positive airway pressure for management of their SDB. Overall, significant improvements were observed in a number of respiratory parameters following decompression including the following: the total apnea-hypopnea index (AHI) (17.5 ± 48.2 vs 6.1 ± 32.7 events/hour; p = 0.001), obstructive AHI (2.1 ± 16.1 vs 1.0 ± 6.6 events/hour; p = 0.005), central AHI (6.3 ± 48.9 vs 2.7 ± 33.0 events/hour; p = 0.005), and the desaturation index (16.7 ± 49.6 vs 3.8 ± 25.3; p = 0.001). CONCLUSIONS Although decompression surgery led to a significant reduction in obstructive and central events, many children continued to have persistent SDB and required additional positive airway pressure therapy. This information is important and relevant for anticipatory guidance around decompression surgery and the necessity for respiratory support for the management of SDB in pediatric patients with CM-I.

Abstract
OBJECTIVE Chiari 1.5 malformation is a subgroup of the Chiari malformation in which tonsillar descent into the foramen magnum is accompanied by brainstem descent. No data exist on whether operative decompression in patients with Chiari 1.5 improves sleep-related breathing disorders (SRBDs) and whether there are radiological parameters predicting improvement. METHODS The authors performed a retrospective cohort study of consecutive pediatric patients with Chiari 1.5 malformation and SRBDs at the Alberta Children's Hospital. An SRBD was characterized using nocturnal polysomnography (PSG), specifically with the apnea-hypopnea index (AHI), the obstructive apnea index, and the central apnea index. Preoperative values for each of these indices were compared to those following surgical decompression. The authors also compared preoperative radiographic factors as predictors to both preoperative AHI and the change in AHI with surgery. Radiological factors included tonsillar and obex descent beneath the basion-opisthion line, the presence of syringomyelia, the frontooccipital horn ratio, the pB-C2 line, and the clivoaxial angle. RESULTS Seven patients (5 males, 2 females) met inclusion criteria. One patient had two surgical decompressions, each with pre- and postoperative PSG studies (n = 8). The median age was 9 years. Before surgical decompression, 75% underwent tonsillectomy/adenoidectomy. The majority (87.5%) experienced snoring/witnessed apnea preoperatively. The median tonsillar and obex descent values were 21.3 mm and 11.2 mm, respectively. The median values for the pB-C2 line and clivoaxial angle were 5.4 mm (interquartile range [IQR] 4.5 mm, 6.8 mm) and 144° (IQR 139°, 167°), respectively. There was a statistically significant change from preoperative to postoperative AHI (19.7 vs 5.1, p = 0.015) and obstructive apnea index (4.5 vs 1.0, p = 0.01). There was no significant change in the central apnea index with surgery (0.9 vs 0.3, p = 0.12). No radiological factors were statistically significant in predicting preoperative AHI and change in AHI. CONCLUSIONS This is the first series of pediatric patients with Chiari 1.5 with SRBDs who demonstrated a marked improvement in their PSG results postdecompression. Sleep apnea has a significant impact on learning and development in children, highlighting the urgency to recognize Chiari 1.5 as a more severe form of the Chiari I malformation.

Abstract
BACKGROUND AND PURPOSE Cerebellar tonsillar herniation arises frequently in syndromic craniosynostosis and causes central and obstructive apneas in other diseases through spinal cord compression. The purposes of this study were the following: 1) to determine the prevalence of cervical spinal cord compression in syndromic craniosynostosis, and 2) to evaluate its connection with sleep-disordered breathing. MATERIALS AND METHODS This was a cross-sectional study including patients with syndromic craniosynostosis who underwent MR imaging and polysomnography. Measures encompassed the compression ratio at the level of the odontoid process and foramen magnum and the cervicomedullary angle. MR imaging studies of controls were included. Linear mixed models were developed to compare patients with syndromic craniosynostosis with controls and to evaluate the association between obstructive and central sleep apneas and MR imaging parameters. RESULTS One hundred twenty-two MR imaging scans and polysomnographies in 89 patients were paired; 131 MR imaging scans in controls were included. The mean age at polysomnography was 5.7 years (range, 0.02-18.9 years). The compression ratio at the level of the odontoid process was comparable with that in controls; the compression ratio at the level of the foramen magnum was significantly higher in patients with Crouzon syndrome (+27.1, P < .001). The cervicomedullary angle was significantly smaller in Apert, Crouzon, and Saethre-Chotzen syndromes (-4.4°, P = .01; -10.2°, P < .001; -5.2°, P = .049). The compression ratios at the level of the odontoid process and the foramen magnum, the cervicomedullary angle, and age were not associated with obstructive apneas (P > .05). Only age was associated with central apneas (P = .02). CONCLUSIONS The prevalence of cervical spinal cord compression in syndromic craniosynostosis is low and is not correlated to sleep disturbances. However, considering the high prevalence of obstructive sleep apnea in syndromic craniosynostosis and the low prevalence of compression and central sleep apnea in our study, we would, nevertheless, recommend a polysomnography in case of compression on MR imaging studies.

Abstract
The need for long-term noninvasive positive pressure ventilation (NiPPV) in children with chronic respiratory failure is rapidly growing. This article reviews pediatric-specific considerations of NiPPV therapy. Indications for NiPPV therapy can be categorized by the cause of the respiratory failure: (1) upper airway obstruction, (2) musculoskeletal and/or neuromuscular disease, (3) lower respiratory tract diseases, and (4) control of breathing abnormalities. The role of NiPPV therapy in select rare conditions (spinal muscular atrophy, congenital central hypoventilation syndrome, cerebral palsy, scoliosis, and Chiari malformations) is also reviewed.

Abstract
PURPOSE Previous studies have attempted to evaluate the utility of preoperative magnetic resonance imaging (MRI) parameters in predicting outcomes in Chiari I malformation. We performed a systematic review and meta-analysis to determine what preoperative imaging features (if any) predict (1) presence of preoperative symptoms or associated findings, (2) need for surgical decompression, or (3) improvement after surgical decompression. METHODS All publications through June 2018 on PubMed, Embase, and Cochrane Library databases were searched using the keywords "Chiari I malformation" AND "decompression" OR "imaging." One thousand two hundred ten publications were identified, and 20 were included for our systematic review; nine were included in the meta-analysis. RESULTS Tonsil position, clivus gradient, and scoliotic curve of > 20° were all associated with the presence of preoperative syrinx. Degree of scoliotic curve was associated with length of syrinx. Pre-operative findings of central syrinx morphology, shorter syrinx, and scoliotic curve < 20° were associated with post-operative stability/improvement. Post-operative symptomatic improvement was associated with preoperative pB-C2 line ≥ 3 mm, absence of scoliosis, and presence of syrinx. By meta-analysis, there was no significant difference in post-operative improvement between patients with and without syrinx (OR = 0.89; 95% CI 0.58-1.37). Meta-analysis showed no significant difference in post-operative improvement between patients with and without basilar invagination (OR = 1.31; 95% CI 0.72-2.36). CONCLUSIONS Multiple studies have attempted to identify preoperative imaging parameters to predict post-operative improvement, but no consistently reliable criteria have been defined. This review and meta-analysis highlight the importance of considering each patient's clinical history and physical exam within the context of associated radiographic abnormalities.

Abstract
OBJECTIVE To better understand the natural history of non-surgical management of chiari 1 anomaly. PATIENTS AND METHODS After obtaining approval of the institutional review board, medical records and radiological exams of patients treated for CM1 at our institution between the years 2010 and 2016 were reviewed. Twenty-nine patients total were included in our study. RESULTS The average age of our patient population was 8.5 years old at the time of diagnosis. The average tonsillar herniation on first MRI was 9.4 mm (+/- 4.6) and the average tonsillar herniation on second MRI was 10.4 mm (+/- 4.8). The average follow up time of our sample of patients was 26 months. Of the 29 patients in our study 9 (31 %) had symptomatic presentation. Interestingly, four of our patients (13.8 %) presented with epilepsy. CONCLUSIONS Our findings support the previous work that nonoperative management is best in asymptomatic or mildly symptomatic chiari patients.

Abstract
PURPOSE Chiari malformation type I is identified as radiological appearance of cerebellar tonsil herniation below the foramen magnum. The wide spectrum of clinical manifestations variably associated sometimes encompasses signs and symptoms whose correlation with the malformation remains debatable. However, a correct clinical framework is relevant in tailoring the strategy of management, and in particular, establishing the appropriate surgical intervention. METHODS An analysis of relevant articles on this issue was performed, involving both single case reports and case series. The papers were obtained from electronic databases including PubMed/MEDLINE and Google Scholar, as well as direct contact with some authors. RESULTS This review focuses on those unusual clinical pictures attributed to Chiari malformation type I (CMI), investigating their actual relationship with the morphological condition. Supposed physiopathogenetic mechanisms and clinical relevance are discussed along with an analysis on the surgical indications and results. CONCLUSION There is no clear explanation on why some patients may exhibit uncommon symptoms, often in association with the most frequent ones, but even reported as single initial clinical occurrence. Their actual incidence may have been roughly underestimated in the literature so far, because of wide heterogeneity of selection and analysis among different studies. Most of the authors appear sharing the impression that CMI surgical decompression plays a significant role in controlling the majority of these unusual symptoms, stressing their actual occurrence in relation with the malformation. A routinely multidisciplinary clinical approach has become advisable to encompass the diversity of conditions potentially associated with CMI and improve the care of CMI patients.

Abstract
PURPOSE Chiari malformation incorporate numerous forms of congenital or acquired cerebellar herniation through the foramen magnum. This may lead to brain stem, high spinal cord and cranial nerve compression resulting in obstructive and central apneas. This review highlights he high prevalence of sleep-disordered breathing in this population and the importance of refering these patients for sleep studies as part of their workup. METHODS A review of the literature was performed through a PubMed and EMBASE search of original articles and reviews using the key words "chiari" "chiari malformation" "hindbrain herniation" "sleep disordered breathing" "obstructive sleep apnea" "central sleep apnea" "sleep study" and "foramen magnum decompression". DISCUSSION We highlight the pathophysiology of sleep disordered breathing in patients with Chiari malformation, how it can be diagnosed and what the treatment options are. CONCLUSIONS Sleep-disordered breathing is highly prevalent in patients with CM1. Clinicians caring for these patients should be aware of this and prioritise sleep diagnostic testing to allow for early diagnosis and management particularly in the presence of neurological symptoms and specific brain MRI pointers.

Abstract
Background Wolfram syndrome is a rare disorder associated with diabetes mellitus, diabetes insipidus, optic nerve atrophy, hearing and vision loss, and neurodegeneration. Sleep complaints are common but have not been studied with objective measures. Our goal was to assess rates of sleep apnea and objective and self-reported measures of sleep quality, and to determine the relationship of sleep pathology to other clinical variables in Wolfram syndrome patients. Methods Genetically confirmed Wolfram syndrome patients were evaluated at the 2015 and 2016 Washington University Wolfram Syndrome Research Clinics. Patients wore an actigraphy device and a type III ambulatory sleep study device and completed the Epworth Sleepiness Scale (ESS), the Pittsburgh Sleep Quality Index (PSQI) and/or the Pediatric Sleep Questionnaire (PSQ). PSQI and PSQ questionnaire data were compared to a previously collected group of controls. Patients were characterized clinically with the Wolfram Unified Rating Scale (WURS) and a subset underwent magnetic resonance imaging (MRI) for brain volume measurements. Results Twenty-one patients were evaluated ranging from age 8.9–29.7 years. Five of 17 (29%) adult patients fit the criteria for obstructive sleep apnea (OSA; apnea-hypopnea index [AHI] ≥ 5) and all 4 of 4 (100%) children aged 12 years or younger fit the criteria for obstructive sleep apnea (AHI’s ≥ 1). Higher AHI was related to greater disease severity (higher WURS Physical scores). Higher mixed apnea scores were related to lower brainstem and cerebellar volumes. Patients’ scores on the PSQ were higher than those of controls, indicating greater severity of childhood obstructive sleep-related breathing disorders. Conclusions Wolfram syndrome patients had a high rate of OSA. Further study would be needed to assess how these symptoms change over time. Addressing sleep disorders in Wolfram syndrome patients would likely improve their overall health and quality of life.

Abstract
ABSTRACT Arnold Chiari malformation (ACM) is the most common cause of central sleep apnea (CSA) in otherwise healthy children. Although there are several case reports and series reported on this topic, there are limited descriptions of the long-term course of these children after the surgical interventions. Posterior fossa decompression surgery to relieve pressure of the herniating cerebellum on the brainstem is generally thought to significantly improve CSA in most cases, however, there are very limited data on the natural course of CSA in children following decompression surgery. There may be a subset of children in whom it may take much longer for CSA to resolve, and in some it may not resolve completely. Hence, these children need to be followed closely with sleep studies to document resolution of CSA. In this case report, we describe a 10-year-old male with severe CSA who was subsequently diagnosed with type 1 ACM and underwent posterior fossa decompressive surgery. However after surgery, although there was improvement in his CSA, he still had a significant degree of residual CSA which required bilevel positive pressure therapy and took more than 7.5 years to resolve. This case report illustrates the need for close follow-up in these children and for providers to understand the natural course so they can accurately counsel families about expectations after surgical treatments.

Abstract
Background Arnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature. Material and Methods A case series with patients with ACM-I treated between 2012 and 2015 was described. The sample consisted of patients who were referred by the Department of Neurosurgery to the Oral and Maxillofacial Surgery Service of Hospital da Restauração in Brazil for the assessment of facial symptomatology. A questionnaire was applied to evaluate the presence of painful orofacial findings. Data are reported using descriptive statistical methods. Results Mean patient age was 39.3 years and the sample consisted mostly of male patients. A high prevalence of headache (50%) and pain in the neck (66.7%) and masticatory muscles (50%) was found. Only one patient reported difficulty in performing mandibular movements and two reported jaw clicking sounds. Mean mouth opening was 40.83 mm. Conclusions ACM-I patients may exhibit orofacial symptoms which may mimic temporomandibular joint disorders. This study brings interesting information that could help clinicians and oral and maxillofacial surgeons to understand this uncommon condition and also help with the diagnosis of patients with similar physical characteristics by referring them to a neurosurgeon. Key words:Arnold-Chiari malformation, facial pain, diagnosis, orofacial.

Chiari 1 Malformation in a Child with Febrile Seizures, Parasomnias, and Sleep Apnea Syndrome. Case Rep Pediatr 2017; 2017:8189790.

Abstract
Introduction The type I is the most common Chiari malformation in children. In this condition, the lower part of the cerebellum, but not the brain stem, extends into the foramen magnum at the base of the skull leading to disturbances in cerebrospinal fluid circulation and to direct compression of nervous tissue. Case report We describe a 4-year-old Caucasian female child with febrile seizures, headache, parasomnias, and a delay of speech. The child underwent a magnetic resonance imaging to investigate these neurological signs, disclosing a Chiari malformation type 1. The polysomnography showed a mild-moderate sleep-disordered breathing, increased number of central sleep apneas, and generalized spike waves at sleep onset. Conclusions Seizures have been seldom described in CM1 patients. The main reasons for performing MRI in this case were frequent seizures, a delay of speech, and headache, leading to an unexpected diagnosis of CM1. Polysomnography detected a discrete SDB.

Abstract
The present statement was produced by a European Respiratory Society Task Force to summarise the evidence and current practice on the diagnosis and management of obstructive sleep disordered breathing (SDB) in children aged 1-23 months. A systematic literature search was completed and 159 articles were summarised to answer clinically relevant questions. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are identified. Morbidity (pulmonary hypertension, growth delay, behavioural problems) and coexisting conditions (feeding difficulties, recurrent otitis media) may be present. SDB severity is measured objectively, preferably by polysomnography, or alternatively polygraphy or nocturnal oximetry. Children with apparent upper airway obstruction during wakefulness, those with abnormal sleep study in combination with SDB symptoms (e.g. snoring) and/or conditions predisposing to SDB (e.g. mandibular hypoplasia) as well as children with SDB and complex conditions (e.g. Down syndrome, Prader-Willi syndrome) will benefit from treatment. Adenotonsillectomy and continuous positive airway pressure are the most frequently used treatment measures along with interventions targeting specific conditions (e.g. supraglottoplasty for laryngomalacia or nasopharyngeal airway for mandibular hypoplasia). Hence, obstructive SDB in children aged 1-23 months is a multifactorial disorder that requires objective assessment and treatment of all underlying abnormalities that contribute to upper airway obstruction during sleep.

Abstract
INTRODUCTION Type I is the most common Chiari malformation in children. In this condition, the lower part of the cerebellum, but not the brain stem, extends into the foramen magnum at the base of the skull leading to intermittent brain hypertension. In symptomatic children, central sleep apneas are shown in polysomnography evaluation. A central apnea index of 1/h or more is considered abnormal, but >5/h is clearly considered pathological. Therefore, central sleep apnea evaluation in pediatric age may show great age-related variability. METHOD AND SUBJECTS We present three patients who were assessed by polysomnography with two different scores for central sleep apneas published in the literature: the method by Scholle (2011) and the American Academy of Sleep Medicine scoring system (2012). CONCLUSIONS We speculated that the Scholle scoring system can be more helpful in assessing children with asymptomatic Chiari 1 malformation for a closer follow-up. More studies are needed.

Abstract
This document summarises the conclusions of a European Respiratory Society Task Force on the diagnosis and management of obstructive sleep disordered breathing (SDB) in childhood and refers to children aged 2-18 years. Prospective cohort studies describing the natural history of SDB or randomised, double-blind, placebo-controlled trials regarding its management are scarce. Selected evidence (362 articles) can be consolidated into seven management steps. SDB is suspected when symptoms or abnormalities related to upper airway obstruction are present (step 1). Central nervous or cardiovascular system morbidity, growth failure or enuresis and predictors of SDB persistence in the long-term are recognised (steps 2 and 3), and SDB severity is determined objectively preferably using polysomnography (step 4). Children with an apnoea-hypopnoea index (AHI) >5 episodes·h(-1), those with an AHI of 1-5 episodes·h(-1) and the presence of morbidity or factors predicting SDB persistence, and children with complex conditions (e.g. Down syndrome and Prader-Willi syndrome) all appear to benefit from treatment (step 5). Treatment interventions are usually implemented in a stepwise fashion addressing all abnormalities that predispose to SDB (step 6) with re-evaluation after each intervention to detect residual disease and to determine the need for additional treatment (step 7).

Abstract
BACKGROUND The prevalence of sleep-disordered breathing (SDB) reported in the literature for Chiari malformation type 1 (CM1) is uniformly high (24% to 70%). In Canada, there is limited access to pediatric polysomnography (PSG). Therefore, the identification of clinical features would be invaluable for triaging these children. OBJECTIVE To identify demographic features, clinical symptoms/signs and radiological findings associated with SDB in a large pediatric cohort with CM1. METHODS A retrospective review was conducted on children with CM1 who underwent baseline PSG. Data were collected on patient demographics (age, sex, weight, height, body mass index), clinical symptoms (chart review and clinical questionnaires), diagnostic imaging of the brain and cervicothoracic spine, and medical history at the time of referral. RESULTS A total of 68 children were included in the review. The mean (± SD) age of the children at the time of PSG was 7.33 ± 4.01 years; 56% (n=38) were male. There was a 49% prevalence of SDB in this cohort based on the overall apnea-hypopnea index. Obstructive sleep apnea was the predominant type of SDB. Tonsillar herniation was significantly correlated with obstructive apnea-hypopnea index (r=0.24; P=0.036). CONCLUSIONS A direct relationship between the degree of cerebellar tonsillar herniation and obstructive sleep apnea was demonstrated. However, further prospective studies that include neurophysiological assessment are needed to further translate the central nervous system imaging findings to predict the presence of SDB.

Abstract
The prevalence of obstructive sleep apnea-hypopnea syndrome in the general childhood population is 1-2% and the most common cause is adenotonsillar hypertrophy. However, beyond adenotonsillar hypertrophy, there are other highly prevalent causes of this syndrome in children. The causes are often multifactorial and include muscular hypotonia, dentofacial abnormalities, soft tissue hypertrophy of the airway, and neurological disorders). Collaboration between different specialties involved in the care of these children is essential, given the wide variability of conditions and how frequently different factors are involved in their genesis, as well as the different treatments to be applied. We carried out a wide literature review of other causes of obstructive sleep apnea-hypopnea syndrome in children, beyond adenotonsillar hypertrophy. We organised the prevalence of this syndrome in each pathology and the reasons that cause it, as well as their interactions and management, in a consistent manner.

Abstract
BACKGROUND Airway patency in both children and adults depends on the tonic and phasic activation of muscles of the tongue and pharynx supplied by the hypoglossal nerve arising at the medullary level. METHODS/PATIENT We report a case of a 2-year-old who after resection of fourth ventricle anaplastic ependymoma developed severe sleep disordered breathing and tongue fasciculation. RESULTS Polysomnography showed severe obstructive sleep apnea with oxygen desaturation to 33%. Magnetic resonance imaging of the brain showed post-surgical effacement of the dorsal lateral medulla. CONCLUSIONS We postulate that damage to the hypoglossal nerve at the level of the medulla contributed to the patient's severe obstructive sleep apnea. Patient was treated with tracheostomy.
