Obstructive sleep apnea (OSA) is a prevalent sleep-disordered breathing with potential long-term major neurocognitive and cardiovascular sequelae. The pathophysiology of OSA varies between individuals and is composed of different underlying mechanisms. Several components including the upper airway anatomy, effectiveness of the upper airway dilator muscles such as the genioglossus, arousal threshold of the individual, and inherent stability of the respiratory control system determine the pathogenesis of OSA...

STUDY OBJECTIVES: Polysomnography is the gold standard for diagnosis and characterization of severity of sleep-disordered breathing. Accuracy and reliability of the technology used are critical to the integrity of the study's interpretation. Strict criteria for obstructive sleep apnea in children are lacking and diagnosis often requires consideration of both frequency of respiratory events in addition to other measures. Current American Academy of Sleep Medicine recommendations for pediatric patients includes use of respiratory inductance plethysmography (RIP) belts, whereas polyvinylidene fluoride (PVDF) belts are currently only acceptable for use in adults...

The cardiac component of cardio-respiratory polysomnography is covered by ECG and heart rate recordings. However, their evaluation is often underrepresented in summarizing reports. As complements to EEG, EOG, and EMG, these signals provide diagnostic information for autonomic nervous activity during sleep. This review presents major methodological developments in sleep research regarding heart rate, ECG, and cardio-respiratory couplings in a chronological (historical) sequence. It presents physiological and pathophysiological insights related to sleep medicine obtained by new technical developments...

The French Society of Research and Sleep Medicine (SFRMS) organized a meeting on obstructive sleep apnea syndrome (OSAS) in children. A multidisciplinary group of specialists (pulmonologist, ENT surgeons, pediatricians, orofacial myofunctional therapists, neurophysiologists, and sleep specialists) reached a consensus on the value of isolated or clustered clinical symptoms and of questionnaires completed by parents in the clinical diagnosis and in assessing the severity of OSAS. Are clinical history with validated questionnaires and a rigorous physical examination sufficient to suspect OSAS, to appreciate its severity, and finally to confirm the diagnosis? Usually, a sleep recording of respiratory parameters remains mandatory for the diagnosis of OSAS to be made...

To investigate whether seizure lateralization affects sleep macrostructure in patients with left and right temporal lobe epilepsy (TLE), as rapid eye movement (REM) sleep is shorter in patients with right hemispheric cerebral infarction than with left. We retrospectively analyzed data from 16 patients with TLE (6 men and 10 women aged 34.9 ± 11.4 years) who underwent polysomnography as well as long-term video electroencephalography. Ten patients were diagnosed with left TLE and six patients with right TLE...

Codeine has been prescribed to pediatric patients for many decades as both an analgesic and an antitussive agent. Codeine is a prodrug with little inherent pharmacologic activity and must be metabolized in the liver into morphine, which is responsible for codeine's analgesic effects. However, there is substantial genetic variability in the activity of the responsible hepatic enzyme, CYP2D6, and, as a consequence, individual patient response to codeine varies from no effect to high sensitivity. Drug surveillance has documented the occurrence of unanticipated respiratory depression and death after receiving codeine in children, many of whom have been shown to be ultrarapid metabolizers...

STUDY OBJECTIVES: To compare polysomnographic parameters in high altitude (HA) native Andean children with low altitude (LA) native peers in order to explain the nocturnal oxyhemoglobin saturation (SpO2) instability reported in HA native children and to study the effect on sleep quality. METHODS: Ninety-eight healthy children aged 7-10 y and 13-16 y were recruited at LA (500 m) or HA (3650 m) above sea level. Physical examination was undertaken and genetic ancestry determined from salivary DNA to determine proportion of European ancestry, a risk factor for poor HA adaptation...

INTRODUCTION: The cause of the sudden infant death syndrome (SIDS) is perhaps the oldest of unsolved mysteries of medicine, possibly dating back to Exodus in Biblical times when Egyptian children died in their sleep as if from a plague. It occurs when infants die unexpectedly with no sufficient cause of death found in a forensic autopsy, including death scene investigation and review of medical history. That SIDS is an X-linked recessive death from infectious respiratory disease of a physiologically anemic infant and not a simple anomalous cardiac or neurological condition is an extraordinary claim that requires extraordinary evidence...

BACKGROUND: Occult bronchial foreign body can be very difficult to diagnose early in an adult patient without acute symptoms. This report describes a rare case of undetected Chinese medicine "Coptis chinensis" aspiration for 10 long years. METHODS: A case was reported that a female patient complained of a 10-year history of productive cough. A battery of tests were given to confirm the diagnosis. RESULTS: Chest computed tomography (CT) showed extensive bronchiectasis and multiple nodules, along with stenosis of left lower lobar bronchus...

OBJECTIVE: To observe the curative effect of needling stimulation of the dorsal segment (7 spots below the spinous processes from T3 to T9) of the Governor Vessel for gastro-esophageal reflux disease (GERD). METHODS: A total of 60 cases of GERD patients were randomly divided into acupuncture group and medication group (n = 30 in each group). For patients of the acupuncture group, the depression spots below the spinous processes from T3 to T9, including both acupoints [Shenzhu (GV 12), Shendao (GV 11), Lingtai (GV 10), Zhiyang (GV 9), Jinsuo (GV 8)] and non-acupoints (T4, T8) were punctured with filiform needles, once every other day for 8 weeks...

For centuries the scope of sleep disorders in medical writings was limited to those disturbances which were either perceived by the sleeper him- or herself as troublesome, such as insomnia, or which were recognized by an observer as strange behavioral acts during sleep, such as sleepwalking or sleep terrors. Awareness of other sleep disorders, which are caused by malfunction of a physiological system during sleep, such as sleep-related respiratory disorders, were widely unknown or ignored before sleep monitoring techniques became available, mainly in the second half of the 20(th) century...

BACKGROUND: In modern medicine, obstructive sleep apnea syndrome (OSAS) is a commonly described sleep disorder with airway obstruction, disrupted sleep, and excessive daytime sleepiness. Since its description in 1976 by Guilleminault et al, numerous epidemiologic studies and systematic reviews, with multiple comorbidities related to cardiovascular sequelae, altered cognitive function, and multiple other potential complications have been described. Multiple risk factors have been identified included obesity, smoking, alcohol consumption, and other factors...

The various ill effects that tobacco smoking has on health have been largely studied, particularly on vascular, neoplastic, and respiratory diseases. Lately, the discussion about the negative impact of cigarette smoking moved towards sleep medicine. Tobacco consumption has been associated with sleep disordered architecture, both during regular intake and after withdrawal. Its effects on sleep disordered breathing (SDB) and especially obstructive sleep apnea syndrome (OSAS) still remain a matter of debate. It is unclear whether smoking represents a risk factor for OSAS or whether smoking cessation has any beneficial effects on OSAS and its therapy...

BACKGROUND: Bariatric surgery patients are vulnerable to sleep-disordered breathing (SDB) early after recovery from surgery and anesthesia. The authors hypothesized that continuous positive airway pressure (CPAP) improves postoperative oxygenation and SDB and mitigates opioid-induced respiratory depression. METHODS: In a randomized crossover trial, patients after bariatric surgery received 30% oxygen in the postanesthesia care unit (PACU) under two conditions: atmospheric pressure and CPAP (8 to 10 cm H2O)...

Over the past three decades exposure to intermittent hypoxia (IH) has generally been considered a stimulus associated with a number of detrimental outcomes. However, there is sufficient evidence to link IH to many beneficial outcomes but they have largely been ignored, particularly in the field of sleep medicine in the United States. Recent reviews have postulated that this apparent contradiction is related to the severity and duration of exposure to IH; mild forms of IH initiate beneficial outcomes while severe forms of IH are coupled to detrimental consequences...
