Nasal cannula use during polysomnography in children aged under three with suspected sleep apnea.

Objective: Early diagnosis of obstructive sleep apnea (OSA) in children is important. The use of a nasal cannula as an airflow sensor during polysomnography has not been evaluated in younger children. The study aims to evaluate the use of nasal cannula in detecting respiratory events in children under three with suspected OSA during daytime nap studies.

The prevalence of narcolepsy in Catalunya (Spain).

Previous studies have estimated an overall prevalence for narcolepsy between 15 and 70 cases per 100 000 inhabitants. We aimed to estimate the prevalence of narcolepsy in Catalunya (Catalonia), a north-east region of Spain (7 424 754 inhabitants), on 31 December 2014 by identifying all living subjects diagnosed with narcolepsy. First, we identified patients diagnosed by one of the 13 sleep, paediatric or neurological departments that perform tests regularly to diagnose narcolepsy.

Effect of adjunctive perampanel on the quality of sleep and daytime somnolence in patients with epilepsy.

This prospective uncontrolled study evaluated the effect of low-dose adjunctive perampanel therapy (4 mg/day for 3 months) on the sleep-wake cycle and daytime somnolence in adult patients (n = 10) with focal seizures. A > 50% reduction in the number of seizures was reported in 80% of the study patients; treatment had no significant effect on any sleep parameters as evident by the Maintenance of Wakefulness Test, Pittsburgh Sleep Quality Index and Epworth Sleepiness Scale scores. Two patients reported dizziness with treatment.

Sleep quality and daytime sleepiness in patients treated with adjunctive perampanel for focal seizures.

Purpose: The purpose of this study was to evaluate subjective sleep quality and daytime sleepiness in patients receiving adjunctive perampanel for focal seizures.

Methods: We conducted a multicenter, prospective, interventional, open-label study in patients aged >16 with focal seizures who received adjunctive perampanel (flexible dosing: 2-12mg). Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and daytime sleepiness with the Epworth Sleepiness Scale (ESS) at baseline and 3 and 6months after initiating perampanel.

A Bayesian cost-effectiveness analysis of a telemedicine-based strategy for the management of sleep apnoea: a multicentre randomised controlled trial.

Background: Compliance with continuous positive airway pressure (CPAP) therapy is essential in patients with obstructive sleep apnoea (OSA), but adequate control is not always possible. This is clinically important because CPAP can reverse the morbidity and mortality associated with OSA. Telemedicine, with support provided via a web platform and video conferences, could represent a cost-effective alternative to standard care management.

Neurophysiological two-channel polysomnographic device in the diagnosis of sleep apnea.

Study Objective: Our objective was to evaluate a portable device (Somté, Compumedics, Australia), which incorporates 2 neurophysiological channels (electroencephalography and electrooculography) with cardiorespiratory monitoring for the diagnosis of obstructive sleep apnea (OSA).

Method: Full polysomnography (PSG) and Somté recordings were simultaneously performed in 68 patients with suspected OSA. Data were analyzed blindly by 2 scorers.

Sleep-related painful erections associated with obstructive sleep apnea syndrome.

Sleep-related painful erection is a rare syndrome recognized by reports of painful nocturnal erection, an association between REM sleep and pain, and the absence of pain during wakeful sexual activity. Approximately 30 cases have been reported in the literature. We add two more cases, each of which seemed to be associated with severe sleep apnea.
