OBJECTIVES/HYPOTHESIS Our previous study showed that modified uvulopalatopharyngoplasty (UPPP), including tonsillectomy, significantly improved nocturnal respiration in obstructive sleep apnea syndrome (OSAS) patients. This is a continuous study of changes in daytime sleepiness and quality of life. STUDY DESIGN Prospective randomized controlled trial (RCT), two parallel arms. METHODS Sixty-...

The theory of indirect reciprocation explains the evolution of cooperation among unrelated individuals, engaging in one-shot interaction. Using reputation, a player acquires information on who are worth cooperating and who are not. In a previous paper, we formalized the reputation dynamics, a rule to assign a binary reputation (good or bad) to each player when his action, his current reputation...

Background: Obstructive sleep apnoea syndrome (OSAS) affects an estimated 2–4% of the middle aged population. Meta-analyses of randomised controlled trials have shown that the severe presentation of the syndrome (apnoea hypopnoea index (AHI) .30/hour) is effectively treated with continuous positive airway pressure (CPAP). Until recently there have been insufficient data to determine whether CPA...

OBJECTIVE To determine whether patients with idiopathic and symptomatic RBD were sleepier than controls, and if sleepiness in idiopathic RBD predicted earlier conversion to Parkinson disease. METHODS The Epworth Sleepiness Scale (ESS) and its determinants were compared at the time of a video-polysomnography for an RBD diagnosis in patients with idiopathic RBD, in patients with Parkinson disea...

We investigated the influence of nocturia and sleep disturbance on health-related quality of life(HRQOL) using the Medical Outcomes Study 8-item Short Form Health Survey (SF-8) in patients with nocturia. We also assessed the effect of therapeutic intervention by means of an anticholinergic agent on the results of the SF-8. One hundred and eighty-four patients who voided at least once per night ...

BACKGROUND Obstructive sleep apnea (OSA) is related to obesity and metabolic disorders. The main clinical symptoms are excessive daytime sleepiness (EDS) and snoring. However, not all patients with OSA manifest EDS. Hypocretin-1, neuropeptide Y, leptin, ghrelin and adiponectin are implicated in both metabolic and sleep regulation, two conditions affected by OSA. We hypothesized that levels of t...

BACKGROUND In the absence of surgical treatments with demonstrable long-term efficacy, conservative treatments for snoring remain appropriate. Only limited evidence evaluating the use of ear protection by partners has been published. METHODS Eligible couples were invited to participate in a two-month trial, with each partner using custom-moulded ear plugs. Five questionnaires were completed b...

This study reports on the effect of fatigue on Urology residents using the daVinci surgical skills simulator (dVSS). Seven Urology residents performed a series of selected exercises on the dVSS while pre-call and post-call. Prior to dVSS performance a survey of subjective fatigue was taken and residents were tested with the Epworth Sleepiness Scale (ESS). Using the metrics available in the dVSS...

PURPOSE Accurate data about sleepiness in professional drivers at the wheel are rare because it is difficult to perform objective and reliable sleepiness tests in the field. In this pilot study, we investigate the practicability, robustness and viability of the pupillographic sleepiness test (PST, F2D by Amtech GmbH, Germany) during routine police controls. PST analyses and quantifies the so-ca...
