Obesity has reached epidemic proportions in the United States with roughly 20% of American children being overweight and has serious consequences such as sleep apnea.Additionally, obesity is known to result in the earlier onset of puberty . Thus, it can be expected that obese children take-on adult characteristics at an earlier chronologic age than their non-obese counterparts. Current guidelines recommend adenotonsillectomy (T+A) as primary and effective therapy for sleep apnea resulting in polysomnographic resolution in 75-100% of patients. Small studies have shown that T+A relieves symptoms in obese children but surgical intervention has been less efficacious in adults. We hypothesize that T+A may be less efficacious in obese adolescents because of earlier onset of puberty imparting more adult characteristics. We further hypothesize that the efficacy of T+A will correlate more closely with Tanner staging than with chronologic age because of the earlier onset of sexual maturation associated with obesity.
" Obstructive sleep apnea"(OSA) is a sleep breathing disorder. When a person with OSA tries to sleep the back of the throat closes and blocks the flow of air into lungs.When this happens, a person's sleep is disrupted, causing minor awakenings(which the individual may not recognize). This occurs many times throughout the night, causing poor sleep quality,excessive daytime sleepiness, poor concentration, and sometimes depression.It is possible that poor outcomes observed in stroke patients with OSA result from these neurocognitive phenomena, presumably by reducing effective participation in rehabilitation activities.OSA is treated with nasal continuous positive airway pressure(CPAP).CPAP therapy keeps the back of the throat open so that airflow is never blocked.The study is designed to investigate whether treatment of OSA with CPAP improves the results of rehabilitation.
The primary objective of the study is to evaluate the safety and tolerability of treatment with PROVIGIL in children and adolescents with excessive sleepiness (ES) associated with narcolepsy or obstructive sleep apnea/hypopnea syndrome (OSAHS), when administered for up to 6 months.
Obstructive sleep apnea (OSA) is a medical problem whose importance is increasing in recognition and awareness. OSA is associated with the development of hypertension and other cardiovascular diseases (1,2). OSA has pathophysiologic characteristics that are known to negatively impact immune function. Both sleep deprivation and hypoxia, hallmarks of OSA, impair immune responses (6,8,11). In addition, patients with OSA are frequently obese and obesity may be associated with increased chance of infections and immune impairment (14,15). Adipose cells are known to secrete cytokines and hormones that are involved in the immune response such as leptin, tumor necrosis factor alpha and interleukin-6 (16-19). Thus, it seems very likely that OSA may impact antigen-specific immune responses. Although it is known that characteristics of OSA impact immune function, it is not known what effects clinical OSA has on immunity. The central hypothesis of this application is that that patients with obstructive sleep apnea will have attenuated cell-mediated and humoral immune responses to influenza vaccine compared to matched control subjects. Our hypothesis has been formulated on the basis that patients with OSA are sleep deprived and experience repeated hypoxemia that negatively impact both humoral and cell-mediated immune responses.
The purpose of this study is to determine if the mandibular advancement by Herbst device is effective in the treatment of moderate obstructive sleep apnea patients.
The purpose of the study is to test the effect of a sleep disorders detection and treatment program for police officers on their safety, quality of life, and job performance. The program is called Operation Healthy Sleep. We will develop and test a sleep health detection and treatment program that we aim to apply nationwide to reduce police officer fatigue and stress; enhance the ability of officers and their families to cope with police work; improve the health, safety and performance of law enforcement officers; and thereby improve public safety. Part of this program will include a questionnaire asking about about work hours and health related issues. We will then look at how these survey data relate with data on police officer safety and job performance that we are collecting through police department's databases. Sleep disorders are common and treatable, but often remain undiagnosed and untreated. Police officers work some of the most demanding schedules known, which increases their risk of sleep disorders. The public expects officers to perform flawlessly, but unrecognized sleep disorders lead to severe disruption of sleep, which significantly reduces an individual's ability to think clearly and perform well. In addition, sleep loss and sleep disruption affect personal health, increasing the risk of gastrointestinal and cardiovascular. We also know that sleep loss increases the risk of injury due to motor vehicle crashes. The goals of Operation Healthy Sleep are to improve officers' health, safety, and performance by reducing the impact of fatigue. The study will take place over two years. In the first year, half of the police officers will take part in Operation Healthy Sleep, and in the second year, the second half will participate. We will carefully select the year 1 and year 2 groups so that the data collected across the two years can be validly compared.
In this study we will examine whether suture repair of the palate, or roof of mouth, has any effect on results of palate surgery performed for treatment of obstructive sleep apnea.
Patients with a clinically indicated sleep study will be enrolled in this study. They will have a diagnostic and a therapeutic sleep study with continuous positive airway pressure ventilation. For both studies a pH probe will be placed nasal to measure the amount of acidic reflux during each study. Baseline levels of reflux from the diagnostic sleep study will be compared to reflux episodes while on continuous positive airway pressure ventilation.
The study is to examine the relationship between sleep apnea and neurocognitive behaviors in children with cleft lip/palate. Describe the incidence and severity of obstructive sleep apnea in an unselected population of grade school aged children with surgically repaired cleft palate. A. Is the incidence of OSA higher in children with cleft palate than age matched historical control groups? B. Are nighttime symptoms an adequate screening tool to exclude the diagnosis of OSA in children with surgically repaired cleft palate? Describe the velopharyngeal closure patterns during speech in an unselected population of grade school aged children with surgically repaired cleft palate. Describe the neurobehavioral phenotype of an unselected population of grade school aged children with surgically repaired cleft palate.
