We conducted a retrospective chart review to examine the efficacy of adenotonsillectomy for the treatment of severe obstructive sleep apnea (OSA) in children. Our study population was made up of 85 patients-58 boys and 27 girls, aged 1 to 17 years (mean: 6.9 ± 4.4)-with severe OSA who had undergone adenotonsillectomy and pre- and postoperative attended polysomnography (PSG) over a 4-year period. Severe OSA was defined as an apnea-hypopnea index (AHI) of >10 events per hour of sleep. Patients who had an underlying genetic or craniofacial anomaly were excluded...

INTRODUCTION: Tissue hypoxia stimulates the production of erythropoietin (EPO), the main effect of which is, in turn, to stimulate erythropoiesis. Sleep apnea-hypopnea syndrome (SAHS) is an entity characterized by repeated episodes of hypoxemia during sleep. OBJECTIVE: To analyze whether hypoxemia stimulated increased urinary excretion of EPO, and if so, to evaluate if treatment with continuous positive airway pressure (CPAP) can inhibit this phenomenon. METHODS: We studied 25 subjects with suspected SAHS who underwent a polysomnography study (PSG)...

BACKGROUND: Genome-wide studies on highland adaptation mechanism in terrestrial animal have been widely reported with few available for aquatic animals. Tibetan Schizothoracinae species are ideal model systems to study speciation and adaptation of fish. The Schizothoracine fish, Gymnocypris przewalskii ganzihonensis had underwent the ecological niche shift from salt water to freshwater, and also experienced a recent split from Gymnocypris przewalskii przewalskii. In addition, G. p. ganzihonensis inhabited harsh aquatic environment including low temperature and hypoxia as well as other Schizothoracinae species, its genetic mechanism of highland adaptation have yet to be determined...

BACKGROUND: Spasticity and spasms are distressing features of the upper motor neuron syndrome (UMNS) following spinal cord injuries (SCI) or multiple sclerosis (MS), and have common therapeutic implications. Despite an increase of antispastic drugs and strategies, sometimes up to the surgical implant of intrathecal baclofen pump, some patients still complain of disabling spasms, which poses diagnostic and therapeutic challenges. Although clinically similar, flexor spasms due to pyramidal tract disruption must be clearly differentiated from periodic limb movements (PLM), often accompanying restless leg syndrome (RLS) and occurring during sleep...

STUDY OBJECTIVES: Sleep bruxism (SB) is common in children and is associated with somatic symptoms and sleep disturbance. Etiological theories posit the role of anxiety, suggesting youth with anxiety disorders may be at high risk for SB, but empirical data are lacking. Furthermore, parent report rather than polysomnography (PSG) has been used to examine SB-anxiety relationships in children. We examined rates of PSG-detected compared to parent-reported SB in children with generalized anxiety disorder (GAD) and healthy controls...

Sleep and circadian rhythm are reported to be severely abnormal in critically ill patients. Disturbed sleep can lead to the development of delirium and, as a result, can be associated with prolonged stay in the intensive care unit (ICU) and increased mortality. The standard criterion method of sleep assessment, polysomnography (PSG), is complicated in critically ill patients due to the practical challenges and interpretation difficulties. Several PSG sleep studies in the ICU reported the absence of normal sleep characteristics in many critically ill patients, making the standard method of sleep scoring insufficient in this patient group...

Study Objectives: This study used ambulatory polysomnography (PSG) to investigate posttraumatic nightmares of PTSD. The key research question was whether posttraumatic nightmares occur in both REM and non-REM sleep, and if so, whether nightmares in each sleep stage differed in content, phenomenology and heart rate response. Underlying sleep disorders were investigated in an exploratory way. Methods: Thirty-five treatment-seeking veterans, current serving military members and emergency service personnel undertook full PSG using the Compumedics (Melbourne, Australia) SomtePSG V1 system, during an inpatient psychiatric admission...

BACKGROUND: The coexistence of obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD) leads to increased morbidity and mortality. The development of home-based screening tests is essential to expedite diagnosis. Nevertheless, there is still very limited evidence on the effectiveness of portable monitoring to diagnose OSAS in patients with pulmonary comorbidities. OBJECTIVE: To assess the influence of suffering from COPD in the performance of an oximetry-based screening test for moderate-to-severe OSAS, both in the hospital and at home...

PURPOSE: Home sleep apnea tests (HSATs) are an alternative to attended polysomnograms (PSGs) when the pre-test probability for moderate to severe OSA is high. However, insurers often mandate use anytime OSA is suspected regardless of the pre-test probability. Our objective was to determine the ability of HSATs to rule in OSA when the pre-test probability of an apnea hypopnea index (AHI) in the moderate to severe range is low. METHODS: Patients who underwent HSATs were characterized as low or high pre-test probability based on the presence of two symptoms of the STOP instrument plus either BMI > 35 or male gender...

Background: Heart rate variability (HRV) represents the sympathetic nervous system activity induced by apnea or hypopnea events among OSAS patients. However, few studies have been conducted to clarify the association between HRV parameters and polysomnography (PSG) diagnostic indices. In our study, we postulate that the prevalence of cardiac arrhythmias is associated with OSAS, and HRV parameters may be an effective method for OSAS screening. Methods: Overall, 168 participants had been collected from 2011 to 2016 in the Second Affiliated Hospital of Soochow University...
