Sleep-disordered breathing (SDB) is relatively common in general population as well as in patients with neuromuscular disease. SDB comprises a wide spectrum of disorders varying from simple snoring to complete closure of the upper airway as seen in obstructive sleep apnoea (OSA). It includes also other disorders like prolonged hypoxemia, hypoventilation, and central sleep apnoea (CSA). ⋯ The involvement of respiratory system in the context of these disorders is the most serious complication, and it is considered as the leading cause of death in those patients. NMD can affect ventilation, cough, swallowing, and phonation. The involvement of respiratory muscles makes NMD patients vulnerable to sleep-disordered breathing with a significant prevalence of SDB among such patients.

Positive airway pressure (PAP) is the standard and most effective treatment for obstructive sleep apnea (OSA). It provides a continuous stream of air under positive pressure through the nose, mouth, or both, which prevents collapse of the upper airway. This allows the patient to breathe freely during sleep. The success of PAP therapy depends largely on the selection of the proper interface (mask). The choice and application of the interface in patients with OSA is a great challenge that greatly affects the long-term compliance to PAP therapy. ⋯ Current evidence suggests that the nasal mask is better tolerated, requires lower pressure to eliminate obstructive respiratory events, and is associated with a better sleep quality and better PAP therapy compliance. Nevertheless, the best mask is the one that patient will wear.

Review Comparative Study
A systematic review of the pharmacological approaches against snoring: can we count on the chickens that have hatched?
Snoring is the sound produced by the vibration of the soft tissues caused by the air passing through a narrow upper airway during sleep. It is usually associated with the conditions that increase upper airway resistance, but can occur in their absence too (primary snoring). Considering its sheer prevalence, the associated comorbidities, like carotid atherosclerosis and the social disorder that it can represent, treatment for snoring must be considered even in the absence of any other medical condition. Treatment options include conservative approaches like weight reduction, smoking and alcohol cessation, sleep positioning, mechanical nasal dilators, and continuous positive airway pressure (CPAP) to more radical approaches like surgery. Till date, we have no drugs for treating the primary pathology of snoring. ⋯ Even though there are no consistent data to support pharmacologic treatment for primary snoring, through the critical analysis of these studies, we have discussed about the future directions for clinical trials in this area to arrive at a clinically meaningful decision.

Obstructive sleep apnoea is recognised as a common but under-diagnosed health issue. Currently, there is very little published data relating to the burden and impact of obstructive sleep apnoea among indigenous populations. The purpose of this review was to investigate the prevalence, impact, risk factors and treatment of obstructive sleep apnoea in indigenous populations in high-income countries. ⋯ Indigenous populations in high-income countries are subject to an overall greater prevalence of obstructive sleep apnoea that is also more severe. A higher prevalence of obesity, alcohol and tobacco use and comorbid medical conditions associated with low socioeconomic status rather than indigenous status per se appears to explain this disparity.

Review Meta Analysis
Post-operative outcomes in adult obstructive sleep apnea patients undergoing non-upper airway surgery: a systematic review and meta-analysis.
With the current obesity epidemic, obstructive sleep apnea (OSA) has become increasingly common. Several studies have reported on the risk of post-operative complications in OSA patients undergoing non-upper airway surgeries. The objective of our study was to systematically review the medical literature reporting the incidence of post-operative complications in patients with OSA. ⋯ OSA patients are at increased risk of post-operative complications from non-upper airway surgeries. Early diagnosis and treatment of OSA might decrease post-operative complications in these patients. There is a need for further studies to assess the benefit of peri-operative treatment of OSA on post-operative outcomes.
