REVIEW
Laurynas Jokubauskas, Aušra Baltrušaitytė, Gaivilė Pileičikienė
The review focuses on the last decade of research regarding the use of various oral appliances (OA) in the management of sleep bruxism (SB) in adults. Sixteen (N = 16) papers out of 641 identified citations involving 398 participants were included in the review. Of them, 7 were randomised controlled trials (RCTs), 7 were uncontrolled before-after studies and 2 were crossover trials. Analysis of the included articles revealed a high variability of study designs and findings. Generally, the risk of bias was low-to-unclear for RCTs and high for crossover studies, whilst the before-after studies exhibited several structural limitations...

PURPOSE OF REVIEW: Sleep-disordered breathing encompasses a broad spectrum of sleep-related breathing disorders, including obstructive sleep apnea (OSA), central sleep apnea, as well as sleep-related hypoventilation and hypoxemia. Diagnostic criteria have been updated in the International Classification of Sleep Disorders, Third Edition and the American Academy of Sleep Medicine Manual for Scoring Sleep and Associated Events. Neurologic providers should have basic knowledge and skills to identify at-risk patients, as these disorders are associated with substantial morbidity, the treatment of which is largely reversible...

Oral appliances that advance the mandible are widely used as alternatives to positive airway pressure (PAP) devices or as primary therapy for obstructive sleep apnea (OSA) in adults. Although PAP is more efficacious at lowering the polysomnographic indices of OSA, the clinical effectiveness of PAP and oral appliances is similar, and patients are more likely to adhere to oral appliance therapy than to PAP treatment. Clinical examination is used to determine the candidacy of oral appliances and to select a particular appliance for a given patient...

Yu-Shu Huang, Christian Guilleminault
Pediatric obstructive sleep apnea (OSA) was initially described in 1976. In 1981, Dr. Guilleminault emphasized that pediatric OSA was different from the clinical presentation reported in adults. It was characterized by more disturbed nocturnal sleep than excessive daytime sleepiness, and presented more behavioral problems, particularly school problems, hyperactivity, nocturnal enuresis, sleep terrors, depression, insomnia, and psychiatric problems. The underlying causes of pediatric OSA are complex. Such factors as adenotonsillar hypertrophy, obesity, anatomical and neuromuscular factors, and hypotonic neuromuscular disease are also involved...

BACKGROUND: Obstructive sleep apnea (OSA) manifests as a reduction or complete cessation of airflow despite an ongoing inspiratory effort, leading to hypoxemia and hypercapnia. The inability to maintain normal breathing reduces the oxygen saturation in blood leading to a cycle of various systemic implications. Hence, a prospective single arm study was planned to evaluate the long-term (2 years) effect of oral appliance on cardiovascular fitness and psychomotor performance in patients with mild to moderate obstructive sleep apnea...

BACKGROUND: Obstructive sleep apnoea (OSA) is a common disorder that may affect at least 2 to 4% of the adult population. Nasal-Continuous Positive Airway Pressure (N-CPAP) is today considered the gold standard for the treatment of OSA. The development of oral appliances (OAs) represents a new approach for the management of this pathology. The aim of this systematic review is to compare the efficacy of OAs and N-CPAP in the treatment of patients with mild to severe OSA. MATERIAL AND METHODS: A PubMed-MEDLINE and Cochrane databases search of articles published between 1982 and 2016 comparing the effect of N-CPAP and OAs in OSA patients was conducted during July 2016...
