Isolated REM sleep behaviour disorder: current diagnostic procedures and emerging new technologies.

J Neurol 2022 Jun 24. Epub 2022 Jun 24.

Wicking Dementia Research and Education Centre, University of Tasmania, Hobart, Australia.

Isolated REM sleep behaviour disorder (iRBD) is characterised by dream enactment behaviours, such as kicking and punching while asleep, and vivid/violent dreams. It is now acknowledged as a prodromal phase of neurodegenerative disease-approximately 80% of people with iRBD will develop dementia with Lewy Bodies, Parkinson's disease or another degenerative brain disease within 10 years. It is important that neurologists and other clinicians understand how to make an early accurate diagnosis of iRBD so that affected people can have the opportunity to take part in clinical trials.

The impact of daytime transoral neuromuscular stimulation on upper airway physiology - A mechanistic clinical investigation.

Physiol Rep 2022 Jun;10(12):e15360

University of California, Division of Pulmonary, Critical Care, Sleep Medicine, and Physiology, La Jolla, California, USA.

There is a need for alternatives to positive airway pressure for the treatment of obstructive sleep apnea and snoring. Improving upper airway dilator function might alleviate upper airway obstruction. We hypothesized that transoral neuromuscular stimulation would reduce upper airway collapse in concert with improvement in genioglossal muscle function. Read More

Secondary Analyses of the Childhood Adenotonsillectomy Trial: A Narrative Review.

JAMA Otolaryngol Head Neck Surg 2022 Jun 23. Epub 2022 Jun 23.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Maryland School of Medicine, Baltimore.

Importance: Adenotonsillectomy, performed for approximately 500 000 children annually in the US alone, is the first line of treatment of pediatric obstructive sleep apnea (OSA). The Childhood Adenotonsillectomy Trial (CHAT), the first randomized clinical trial to test the efficacy of adenotonsillectomy, compared the management of pediatric nonsevere OSA by early adenotonsillectomy (eAT) vs watchful waiting with supportive care. Since the publication of the primary article in 2013, the CHAT study data set were made available via the National Sleep Research Resource, which allowed researchers to address a range of additional clinical questions relevant to the care of children with OSA.

Bright Light During Wakefulness Improves Sleep Quality in Healthy Men: A Forced Desynchrony Study Under Dim and Bright Light (III).

J Biol Rhythms 2022 Jun 22:7487304221096910. Epub 2022 Jun 22.

Chronobiology Unit, Groningen Institute for Evolutionary Life Sciences, University of Groningen, Groningen, the Netherlands.

Under real-life conditions, increased light exposure during wakefulness seems associated with improved sleep quality, quantified as reduced time awake during bed time, increased time spent in non-rapid eye movement (NREM) sleep, or increased power of the electroencephalogram delta band (0.5-4 Hz). The causality of these important relationships and their dependency on circadian phase and/or time awake has not been studied in depth. Read More

The case for the pharyngeal flap pharyngoplasty in the management of velopharyngeal dysfunction.

J Plast Reconstr Aesthet Surg 2022 Apr 27. Epub 2022 Apr 27.

Department of Plastic & Reconstructive Surgery, Children's Health Ireland at Crumlin, Dublin, Ireland; Department of Surgery and Paediatrics, Trinity College Dublin, Ireland.

Velopharyngeal dysfunction (VPD) occurs when there is inadequate closure of the velopharyngeal sphincter during speech. An incompetent velopharyngeal sphincter may require surgical intervention to create a functional seal between the oropharynx and the nasopharynx during speech. To date, no single pharyngoplasty procedure has emerged as superior to another, and the comparison of results between studies has been limited by variation in outcomes reporting. Read More

Cost-minimisation analysis of polysomnography and pulse oximetry in a risk stratification protocol for paediatric adenotonsillectomy.

ANZ J Surg 2022 Jun 20. Epub 2022 Jun 20.

Department of Otolaryngology, Head & Neck Surgery, Monash Health, Melbourne, Victoria, Australia.

Background: Severe obstructive sleep apnoea (OSA) is associated with increased risk of respiratory compromise in the post-operative period following adenotonsillectomy (AT). This study analyses the economic cost of polysomnography or overnight oximetry as part of pre-operative risk stratification in paediatric AT, supplementing previously published research demonstrating the efficacy of this protocol in predicting respiratory complications.

Methods: This cost-minimisation analysis examines costs associated with pre-operative overnight oximetry and polysomnography in triaging paediatric patients older than 2 years old, with no major comorbidities except for OSA, undergoing AT for OSA (n = 1801) to either a secondary or quaternary Australian hospital.
