NCT03788733
Burning mouth ( BMS) syndrome is the oral disorder characterized by an intraoral burning sensation for which no medical or dental cause can be found. The Headache Classification Committee of the International Headache Society (IHS) defines (BMS) as an ''intraoral burning or dysaesthetic sensation, recurring daily for more than 2 hours per day over more than 3 months, without clinically evident causative lesions''. (BMS) is a common, chronic problem that has a negative impact on quality of life. A wide variety of medications have been proposed for treating (BMS) both topical and systemic. Unfortunately, no treatment seems to offer assured results. Melatonin is a naturally occurring hormone secreted by the pineal gland. It has soporific effects with oral administration and is well tolerated. It enhances sleep Melatonin also may help sleep disturbances associated with (BMS) ; however, this remains to be proven.
NCT01342328
Cognitive dysfunction, either alone or as an element in the syndrome of delirium, is a common occurrence with an incidence as high as 75% in intensive care unit (ICU) patients and can independently result in serious consequences including higher mortality rate. Delirium develops through a complex interaction between the patient's baseline vulnerability (risk factors) and precipitating factors such as disruption of sleep that may occur during hospitalization. While sedative-hypnotic agents that are used to facilitate hypnosis and the management of mechanically ventilated patients converge on the neural substrate that mediate endogenous sleep, they do so at different juncture points depending on its molecular mechanism of hypnotic action. Hypnotic agents that modulate the GABAA receptor converge at the level of the hypothalamus while α2 adrenergic agonists converge on sleep pathways within the brainstem. This translational project seeks to determine whether sedation mediated by activation of α2 adrenoceptors (dexmedetomidine) is more like natural sleep than that provided by a sedative agent that modulates the GABAA receptor (propofol). The investigators will examine volunteers who will be monitored continuously by electroencephalography (EEG) and whole-brain functional connectivity by magnetoencephalography (MEG) during each of three sleep stages, namely, that induced by dexmedetomidine, propofol, or saline (natural sleep, control). The two drug-induced sleep regimens will be compared to natural sleep using EEG and brain connectivity by MEG
