“…Background data for each group are set out in Tables 1 and 2. <<Insert Tables 1 and 2 Chen et al, 2002;Johns, 1992;Johns, 2000;Vignatelli et al, 2003;Violani et al, 2003) with scores exceeding 10 indicative of some form of sleep disorder (Johns & Hocking, 1997). The ESS contains eight items, which a participant has to score on a scale of 0 (would never doze off in this situation) to 3 (high chance of dozing off in this situation).…”

Objectives: Research suggests that ecstasy users exhibit psychobiological changes relative to nonusers such as altered sleep patterns and cognitive deficits. In turn, it has been suggested that sleep quality may be a mediator of such cognitive deficits in ecstasy users. The present study sought to investigate this proposed relationship.Methods: Aspects of cognitive functioning in 104 ecstasy users and 103 nonusers obtained from our previous studies were reanalysed to explore the extent to which ecstasy-related group differences were attributable to differences in sleep quality.Cognitive function was assessed via the computation span test, consonant updating, paired associate learning, syllogistic reasoning and word fluency. Sleep quality was measured via the Epworth Sleepiness Scale (ESS), and the Karolinska Sleepiness Scale (KSS). Results: Ecstasy users performed worse than nonusers on all cognitive measures. While no differences were observed on the ESS, ecstasy users reported greater tiredness at the beginning of testing than nonusers. When the sleep variables were included as covariates, the effects of ecstasy on all cognitive measures remained significant. Conclusions: The results of the present study suggest little evidence for the mediating effects of sleep on cognitive function in ecstasy users.

“…Patients were also divided into 4 quartiles of subjective sleepiness according to their ESS: "normal" (0-5), "non-sleepy" (6-9), "sleepy" (10)(11)(12)(13)(14), and "very sleepy" (15)(16)(17)(18)(19)(20)(21)(22)(23)(24). The latter 3 categories for sleepiness were compared with the reference category (i.e., "normal").…”

BRIEF SUMMARYCurrent knowledge/Study Rationale: The purpose of this study was to determine whether the risk of MVCs was higher in patients with OSA than in the general community and, if so, the nature of the risk. To do so, we examined the relationships of near-misses and MVCs with OSA severity, degree of daytime sleepiness, and other potential risk factors with a study design powered to address these associations using standardized measurement technologies for OSA. Study Impact: Our study confi rms that sleep clinic patients with untreated OSA have signifi cantly more crashes than the general population. There is a strong association between excessive daytime sleepiness and increased report of near-misses supporting the observation that it is those patients with increased sleepiness regardless of OSA severity that are most at risk.

“…He also completed the Epworth Sleepiness Scale (ESS), a test to identify degrees of sleepiness [18], with a score of 12. Investigations have shown that a score of 10 or 11 is considered to be the upper parameter for normal [19,20]. After these studies, the patient was discharged with a diagnosis of moderate OSAS (AHI=20/h) and a request of an oral evaluation.…”

Abstract:Purpose: Obstructive sleep apnea (OSA) is a common disease that is estimated to affect 2% of middle-aged women and 4% of middle-aged men. Reported risk factors include obesity, increased neck circumference, male sex and anatomical abnormalities of the face. Although edentulism is reported to change the anatomy and also impair the function of the upper airway, it has not been typically recognized as a risk factor for sleep-related breathing disorders. Methods:The subject of this report is a 55 years old man with a body mass index (BMI) of 33 kg/m 2 . Cephalometric assessments of head radiographs taken in the lateral plane with and without dentures were performed; mandible planehyoid (MP-H) distance and the posterior airway space (PAS) were measured. Oxygen saturation (SaO 2 ) and apnea/hypopnea index (AHI) were evaluated.Results: A comparison of the polysomnographies taken with and without wearing the dentures during the night showed that AHI was reduced (from 20.0/h to 5.7/h) and mean SaO 2 increased (from 94.0% to 96.0%). Cephalometric analysis showed that the removal of dentures led to a striking increase in the anteroposterior oropharyngeal wall distance from 5 mm to 10 mm, while the mandible plane-hyoid distance does not change. Conclusions:These findings were consistent with the hypothesis that edentulism not always worse OSA by an oropharyngeal collapse. Given the common occurrence of both conditions among the elderly, such as the reduction of obstructive sleep apneas with or without dentures, the observed relationship requires further investigations on the mechanisms through which the loss of teeth could help upper airway collapse during the night. In the present paper a case of reduction of OSA without dentures during sleep is shown.
