Arnold Chiari malformation (ACM) is herniation of brain stem structures, especially cerebellar tonsils, from the foramen magnum into the cervical spinal canal. Sleep-related respiratory disorders are reported at a higher rate in this patient group than the general population, at about 60-75%. A 43-year-old male patient was diagnosed with ACM type 1.5 at the center where he applied with complaints of weakness in the extremities, speech disorder and syncope triggered by coughing, and a decompression of posterior fossa (PFD) was applied to the patient...

Patients with Chiari type I malformation may also present with sleep disordered breathing mainly central sleep apnea. Here, we report a patient with Chiari I malformation referred to our clinic because of snoring and sleep disordered breathing. He was a 28-year-old man referred to us for evaluation of snoring. An overnight polysomnography revealed central sleep apnea. On further evaluation of central sleep apnea, the patient found to have Chiari malformation type I on brain MRI. The patient developed obstructive sleep apnea after surgery for Chiari malformation...

BACKGROUND: Prader-Willi syndrome (PWS) is a neurodevelopmental disorder characterized by multiple respiratory, cognitive, endocrine, and behavioral symptoms, such as central apnea, intellectual disabilities, exaggerated stress responses, and temper tantrums. The locus coeruleus noradrenergic system (LC-NE) modulates a diverse range of behaviors, including arousal, learning, pain modulation, and stress-induced negative affective states, which are possibly correlated with the pathogenesis of PWS phenotypes...

BACKGROUND: Nasal obstruction is a common complaint in patients with sleep-disordered breathing and obstructive sleep apnea (OSA). Although topical nasal treatments (TNTs) have been shown to reduce nasal resistance and improve nasal obstruction, there is conflicting evidence regarding the role of TNTs in adult OSA. In this systematic review and meta-analysis we aim to evaluate the role of TNTs in adults with OSA. Data sources used included PubMed, Ovid MEDLINE, and Cochrane Central, from January 2001 to July 2019...

BACKGROUND: Increased sympathetic drive is the key determinant of systolic heart failure progression, being associated with worse functional status, arrhythmias, and increased mortality. Central sleep apnea is highly prevalent in systolic heart failure, and its effects on sympathovagal balance (SVB) and hemodynamics might depend on relative phase duration and background pathophysiology. OBJECTIVE: This study compared the effects of central apneas in patients with and without systolic heart failure on SVB and hemodynamics during sleep...

INTRODUCTION: Obstructive sleep apnoea (OSA) and type 2 diabetes mellitus (T2DM) often occur concurrently, and untreated OSA may potentially amplify the high risk of cardiovascular disease in T2DM. Compliance with continuous positive airway pressure (CPAP), the conventional treatment for OSA, can be poor and considering weight loss is the most effective treatment for OSA. This trial examines whether the glucagon-like peptide-1 receptor agonist liraglutide, a glucose-lowering therapy associated with significant weight loss used in T2DM, can improve the severity and symptoms of OSA...

BACKGROUND: The significance of arousal in apnea termination in preterm infants is not known. METHODS: We investigated the appearance of arousals from sleep with polysomnography for 21 preterm infants at a median age of 36 gestational weeks. RESULTS: The polysomnographic appearance of sleep was fragmented by frequent arousals. The number of spontaneous arousals unrelated to apneas was 18 per h in sleep; higher in rapid eye movement (REM) sleep than in non-REM sleep (p < 0...

RATIONALE: Sleep study interpretation in children needs to be based on age-specific normal values. While several studies have reported normal cardiorespiratory parameters during sleep in children and adolescents, few have included younger children. OBJECTIVES: To describe cardiopulmonary indices specifically oxygen saturation, heart rate, as well as frequency of obstructive and central apneas in healthy one-year-old Canadian infants during sleep. METHODS: Home sleep cardiorespiratory monitoring (HSCM) was performed among infants participating in the Edmonton sub-cohort of the Canadian Healthy Infant Longitudinal Development (CHILD) Study at their one-year follow-up visit...

BACKGROUND: Obstructive sleep apnea (OSA) patients are at increased risk for pulmonary and cardiovascular complications; perioperative mortality risk is unclear. This report analyzes cases submitted to the OSA Death and Near Miss Registry, focusing on factors associated with poor outcomes after an OSA-related event. We hypothesized that more severe outcomes would be associated with OSA severity, less intense monitoring, and higher cumulative opioid doses. METHODS: Inclusion criteria were age ≥18 years, OSA diagnosed or suspected, event related to OSA, and event occurrence 1992 or later and <30 days postoperatively...

STUDY OBJECTIVES: The impact of vitamin D on human health including sleep has been well described in adults. Its deficiency has been associated with multiple sleep disorders such as decrease in sleep duration, worsening of sleep quality, and even OSA. Such correlation is less evident in the pediatric population. In the current study, we examined the relationship between sleep architecture and vitamin D status in children referred to a sleep clinic. METHODS: This was a retrospective-cohort study in a tertiary care children's hospital over a 1-year period...

BACKGROUND: Adaptive servoventilation (ASV) is a recently developed ventilation mode designed to stabilize ventilation in patients with central sleep apnea and Cheyne-Stokes respiration. Alternatively, modes aiming to maintain average ventilation over several breaths, such as average volume-assured pressure support (AVAPS) and intelligent volume-assured pressure support (iVAPS), could be efficient during ventilation instability by reducing central events. These modes are available on a variety of devices...
