Objective To assess the clinical significance of nasal nitric oxide (nNO) and fractional exhaled nitric oxide (FeNO) concentrations in children with sleep-disordered breathing (SDB). Methods Enrolled in this study were 30 children with SDB and 15 healthy children. The nNO and FeNO concentrations were measured noninvasively using a NIOX MINO system (Aerocrine AB, Solna, Sweden). SPSS statistics 20...
The prevalence of REM sleep behavior disorder (RBD) has been estimated to be around 0.5 % in the general population, while in patients with Parkinson’s disease the frequency ranges between 40 and 46 %. Current criteria for the diagnosis of RBD do not specify a clear quantitative cut-off for muscle activity, that is, how much EMG activity during REM sleep is normal, and at what point does it become...
A new diagnostic method is described which identifies the presence of waveform clusters indicative of OSA, and an illustrative OSA screening system is presented which applies the new cluster analysis method to the oximetry waveform. Rather than using the conventional identification of an excess average number of isolated events to infer the presence of upper airway instability, cluster analysis identifies...
