Sleep apnea and oxygen saturation in adults at 2640m above sea level
Conclusions Patients with OSA at 2640m have nocturnal desaturation lower than 88%, which decreases with higher severity of OSA. The clinical impact of sleep disorders at this point may be greater than at sea level and should be studied. (Source: Sleep Science)

A boy infant with sleep related rhythmic movement disorder showing arm banging
Discussion We diagnosed him as having arm banging type of sleep related rhythmic movement disorder. To our knowledge, no precise description on this type of sleep related rhythmic movement disorder has been found. In addition, this patient seemed to be the youngest case of sleep related rhythmic movement disorder showing arm banging. (Source: Sleep Science)

Update of sleep alterations in depression
Publication date: Available online 27 September 2014 Source:Sleep Science Author(s): Andrés Barrera Medina , DeboraYoaly Arana Lechuga , Oscar Sánchez Escandón , Javier Velázquez Moctezuma Sleep disturbances in depression are up to 70%. Patients frequently have difficulty in falling asleep, frequent awakenings during the night and non-restorative sleep. Sleep abnormalities in depression are mainly characterized by increased rapid eye movement (REM) sleep and reduced slow wave sleep. Among the mechanisms of sleep disturbances in depression are hyperactivation of the hypothalamic-pituitary-adrenal axis, CLOCK gen...

Restless leg syndrome exacerbated by amytriptiline in a patient with Duchenne Muscular Dystrophy
We report an unusual case of a Duchenne Muscular Dystrophy(DMD) patient who initiated a restless leg syndrome after the use of amytriptiline. The prescription and use of this medication for patients with persistent neuropathic pain is relatively common, especially for patients with DMD. Normally, this medication is well tolerated, however, we now report the occurrence of an induction or intensification of a restless leg syndrome case in a young patient with DMD, treated with amytriptiline for his chronic pain.

Nonparametric methods in actigraphy: An update
Publication date: Available online 29 September 2014 Source:Sleep Science Author(s): Bruno da Silva Brandão Gonçalves , Paula R.A. Cavalcanti , Gracilene R. Tavares , Tânia F. Campos , John F. Araujo Circadian rhythmicity in humans has been well studied using actigraphy, a method of measuring gross motor movement. As actigraphic technology continues to evolve, it is important for data analysis to keep pace with new variables and features. Our objective is to study the behavior of two variables, interdaily stability and intradaily variability, to describe rest activity rhythm. Simulated data and actigraphy data ...

Temporal sleep patterns in adults using actigraph
Publication date: Available online 5 October 2014 Source:Sleep Science Author(s): Lia Matuzaki , Rogerio Santos-Silva , Elaine Cristina Marqueze , Claudia Roberta de Castro Moreno , Sergio Tufik , Lia Bittencourt The aim of the present study was to characterize the temporal patterns of sleep and wakefulness in a sample of the adult subjects from São Paulo city. All subjects filled the Morningness/Eveningness Questionnaire (MEQ) and wore an actigraph for at least three consecutive days. A total of 359 subjects were considered for the analyses. The mean age was 43±14 years, the mean body mass index was 26.7±5.7k...

The Impact of Sound on Electroencephalographic Waves during Sleep in Patients Suffering from Tinnitus
Publication date: Available online 5 October 2014 Source:Sleep Science Author(s): Marisa Pedemonte , Martín Testa , Marcela Díaz , Diego Suárez-Bagnasco Based on the knowledge that sensory processing continues during sleep and that a relationship exists between sleep and learning, a new strategy for treatment of idiopathic subjective tinnitus, consisted of customized sound stimulation presented during sleep, was tested. It has been previously shown that this treatment induces a sustained decrease in tinnitus intensity; however, its effect on brain activity has not yet been studied. In this work, we compared the ...

Excessive daytime somnolence and cardiovascular health: A population-based study in rural Ecuador
Publication date: Available online 16 October 2014 Source:Sleep Science Author(s): Oscar H. Del Brutto , Robertino M. Mera , Mauricio Zambrano , Pablo R. Castillo In a population-based study conducted in rural Ecuador, 635 stroke-free persons aged ≥40 years were interviewed with the Epworth sleepiness scale and screened to assess their cardiovascular health (CVH) status. Excessive daytime somnolence was present in 22% persons and a poor CVH status in 69%. In a generalized linear model after adjusting for age and sex, excessive daytime somnolence was not associated with a poor CVH status or with any of the individ...

Sleep disorders: A review of the interface between restless legs syndrome and iron metabolism
The objective of this study was to review in the literature the relationship between iron metabolism and RLS. With an initial search using the keywords combination “Iron Metabolism OR Iron Deficiency AND Restless Legs Syndrome,” 145 articles were screened, and 20 articles were selected. Few studies were found for this review in the period of 2001–2014, however, the correlation between RLS and iron was evident. (Source: Sleep Science)
