Article Abstract
Restrictive lung disease (predominantly in patients with neuromuscular disease (NMD) and ribcage deformity) may induce chronic hypercapnic respiratory failure, which represents an absolute indication to start home NIV (HNIV). However, in the early phases of NMD, patients may present only diurnal symptoms or orthopnoea and sleep disturbances with normal diurnal gas exchange. The evaluation of respiratory function decline may predict the presence of sleep disturbances (SD) and nocturnal hypoventilation that can be respectively diagnosed with polygraphy and PCO transcutaneous monitoring. If nocturnal hypoventilation and/or apnoea/hypopnea syndrome are detected, HNIV should be introduced. Once HNIV has been started, adequate follow-up is mandatory. The ventilator's built-in software provides important information about patient adherence and eventual leaks to correct. Detailed data about pressure and flow curves may suggest the presence of upper airway obstruction (UAO) during NIV that may occur with or without decrease in respiratory drive. Etiology and treatment of these two different forms of UAO are different. For this reason, in some circumstances, it might be useful to perform a polygraph. PtCO monitoring, together with pulse-oximetry, seem to be very important tools to optimize HNIV. The role of HNIV in neuromuscular disease is to correct diurnal and nocturnal hypoventilation with the consequence of improving quality of life, symptoms, and survival.

The prevalence of vagus nerve stimulator-induced sleep disordered breathing in children with refractory Epilepsy: A retrospective cohort study.
Sleep Med

Rationale: Vagus nerve stimulators (VNS) can reduce seizure burden in children but may result in sleep-disordered breathing (SDB). Our objectives were to assess the prevalence of SDB in children with epilepsy using polysomnography (PSG) before and after VNS implantation as well to explore management strategies for VNS-induced SDB.
Methods: A retrospective cohort study was conducted (May 2019 to September 2024) of children aged 0-18 years old with refractory epilepsy and VNS insertion at The Hospital for Sick Children, Toronto, Canada.
Resilience Story of Managing Severe Obstructive Sleep Apnea With Hypoventilation Secondary to SELENON (SEPN1)-Related Myopathy.

SELENON-related myopathy is a rare autosomal recessive disorder characterised predominantly by muscle weakness; sleep-disordered breathing and respiratory failure are frequent complications. We report a 15-year-old male with genetically confirmed SELENON-RM and a 12-year history of progressive sleep-related breathing disorders, managed with overnight volume-targeted pressure support (VtPS) positive airway pressure (PAP) plus supplemental oxygen. Longitudinal polysomnography (PSG) revealed evolution from mild REM-predominant hypopneas to severe obstructive sleep apnea (OSA) with hypoventilation.

Study Objectives: Sleep-disordered breathing (SDB) is an increasingly recognized co-morbidity in childhood obesity. SDB may contribute to the excessive weight gain; however, diagnosis and treatment strategies are not well-defined during childhood. Most pediatric studies focus solely on obstructive sleep apnea (OSA), although hypoventilation may play a separate but pivotal role in the course of the condition.

Background: Continuous Positive Airway Pressure (CPAP) initiation should ideally be conducted through CPAP titration in a sleep laboratory according to the American Academy of sleep Medicine recommendations. The objective of this retrospective study was to evaluate the efficacy of two continuous positive airway pressure (CPAP) titration methods-short-supervised in-sleep-laboratory titration and longer, unsupervised hospitalization-based titration-in children under 2 years requiring noninvasive ventilation (NIV) for severe obstructive sleep apnea syndrome (OSAS).
Methods: The participants were allocated based on sleep laboratory availability, with the short-supervised procedure involving in-lab nap polysomnography and pressure adjustments, while the long-unsupervised approach involved hospitalization, the ventilator's built-in software analysis, and overnight gas exchange-based guidance.
Sleep Disorders in Children with Rett Syndrome.

Rett syndrome (RTT) is an X-linked neurodevelopmental disorder marked by neurological regression, autonomic dysfunction, seizures, and significant sleep and breathing abnormalities. About 80% of affected individuals, especially young children, experience sleep disturbances such as insomnia, sleep-disordered breathing, nocturnal vocalizations, bruxism, and seizures. Breathing irregularities during sleep-like apnea, alternating hyperventilation, and hypoventilation-are common, with both obstructive and central sleep apnea identified through polysomnography.
