Material and Method: Electronic searching was done in PubMed, Medline, EMBASE and CENTRAL databases. Inclusion criteria were: dental, oral and maxillofacial oriented articles. Exclusion criteria: cardiac, obesity and non dental oriented articles were excluded. Result: 59 articles meet the criteria. Conclusion: Obstructive sleep apnea (OSA) is a potentially life threatening disorder characterized by repeated collapse of the upper airway during sleep, with periodic cessation of breathing for more than ten seconds. The frequency of obstructive sleep apnea has been found to increase with age;ranging from two percent among children to two and half percent - six percent among adolescents. Overnight polysomnographic test at specialized sleep clinics remains the gold standard for diagnosing obstructive sleep apnea disorder. Management of this condition can be performed via surgical and non surgical methods. Continuous positive airway pressure represents the first line of treatment for most patients with obstructive sleep apnea.展开更多

While it is known that PAP is efficacious for controlling breathing events during sleep when it is worn at the right pressure for the amount of time prescribed, there is less clear data on how well it improves sleep quality. There are few studies that have examined the effectiveness of PAP therapy on sleep quality. Methods: OSA participants (n = 241) from a larger trial examining a PAP adherence were included. Participants were provided with PAP instruction and followed at 2 months and 4 months. PAP adherence was measured as the number of hours per night at prescribed pressure, an objective measure of treatment adherence. The Pittsburgh Sleep Quality Index (PSQI) was used as the primary measure of sleep quality. Results: The PSQI was significantly correlated with PAP adherence at both the 2-month and 4-month time points, such that lower sleep quality was associated with lower PAP use. This finding held for the sleep disturbance subscale of the PSQI. Over 55% of those using PAP therapy at the 4-month time point continued to report significantly disturbed sleep. Discussion: This study shows that PAP therapy does not appear to improve sleep quality to a degree that would be expected. Over half of those patients using PAP therapy still experienced disturbed sleep. Whether the disturbed sleep is directly attributable to the PAP device itself or to disturbed sleep secondary to uncontrolled OSA when PAP is not worn is worthy of further investigation.展开更多

There are a multitude of sleep-wake disturbances that worsen the patient’s quality of life, insomnia and excessive daytime sleepiness being two of the most frequent complaints. The aim of this review is to highlight the most relevant clinical trials conducted during the last 5 years, focusing on the problematic of insomnia and daytime sleepiness correlated with Parkinson’s Disease and its treatment. Three electronic databases (Pubmed, Science Direct and Google Scholar) were searched during March and April 2020 for articles on this topic, finally selecting 21 most relevant articles that we have included in this review. Interesting aspects regarding correlation between sleep-wake disorders and Parkinson’s disease were found, showing that non-motor symptoms may be independent of the disease itself. We discussed the most recent advances in treatment opportunities and the adverse effects, with insomnia and daytime sleepiness among the most common complaints. Besides newly developed pharmacological therapy, consisting in mostly dopaminergic agonists or levodopa adjuvant drugs. Other possibly effective therapies on sleep-wake disorders such as deep brain stimulation, dietary changes, bright light therapy and alternative medicine protocols are also reviewed. Insomnia and excessive daytime sleepiness are common complaints in Parkinson’s disease patients, being either self-standing non-motor symptoms or adverse effects of the antiparkinsonian medication, diminishing patient’s quality of life. The effervescence of research on this topic shows promising results, with new clinical trials still to come in the near future.展开更多

OSAS has a frequency of 4 percent and is classified according to the number of obstructive sleep apnea-hypopnea episodes. The OSAS diagnostic path starts with the evaluation of the patient’s clinical framework and follows an instrumental procedure, depending on the clinical severity of the patient. Dental practitioners have the ability to intercept early on the signs and symptoms of OSAS. At the same time, they can assess whether the patient has the indications for treatment with specific oral devices (Oral Appliances, OA). The purpose of this paper is to provide guidance for dental management of obstructive sleep apnea syndrome in adult individuals.展开更多
