    Full Text Available Objetivos: determinar las características epidemiológicas de los pacientes estudiados por apnea obstructiva del sueño (AOS en el Hospital San Juan de Dios, Costa Rica, de enero de 2005 a diciembre de 2011. Métodos: se trata de un estudio descriptivo-retrospectivo de los pacientes con el cuadro clínico de AOS, atendidos en Consulta Externa de Neumología del Hospital San Juan de Dios, de enero de 2005 a diciembre de 2011. La información se obtuvo de los expedientes médicos, por medio de una ficha de recolección de datos. Con base en los resultados se realizó el análisis estadístico. Resultados: la población total fue de 182 pacientes, de los cuales al 88% se le diagnosticó el síndrome en estudio. El género femenino predominó en la AOS de grado leve a moderado, y el masculino, en el severo. El aumento de la edad y el índice de masa corporal correlacionaron con la mayor probabilidad del diagnóstico de AOS (p < 0.01. Respecto a la comorbilidades presentes, hubo mayor porcentaje de hipertensión arterial (55,5% y la diabetes mellitus (40.3%, independientemente del grado de severidad. Los pacientes con grado severo tuvieron mayor índice en la escala de somnolencia diurna de Epworth. No se encontró asociación significativa entre AOS y enfermedad pulmonar obstructiva crónica, infarto agudo al miocardio, accidente vascular cerebral y arritmia. Conclusiones: este es el primer estudio que se realiza en el país sobre esta patología. La polisomnografía fue un método diagnóstico eficaz en nuestro medio y debería implementarse en otros hospitales de la seguridad social, con el fin de determinar la prevalencia del problema y ofrecer a los pacientes la terapéutica de presión positiva continua de la vía aérea. Los datos epidemiológicos obtenidos de la población, no distan de lo reportado a nivel internacional en lo que respecta a factores de riesgo y enfermedades concomitantes.

    Full Text Available El presión continua positiva en la vía aérea (CPAP nasal se considera como el tratamiento ideal para el tratamiento de Síndrome Apnea Obstructiva del Sueño (SAOS, debido a que es conservador y reversible, sin embargo, existe una pobre tasa de adherencia en su utilización a largo plazo, La cirugía podrá complementar de una manera importante aquellos casos en las cuales el CPAP no es tolerado. La cirugía para el SAOS se deberá realizar tomando en cuenta el grado de apnea obstructiva, el lugar de mayor obstrucción y la experiencia del equipo médico. Mientras más severo sea el SAOS se podrá ser más agresivo con la terapia quirúrgica. El lugar de obstrucción no deberá ser considerado de una manera simplista en la que se define un solo lugar de obstrucción, sino como una alteración general de la vía aérea donde el cirujano deberá actuar para remodelarlo de una manera efectiva. Se describen en el trabajo diversos tipos de cirugía y su eficacia en el SAOS de acuerdo al área anatómica comprometido (nariz, cirugía de adenoides, amígdalas, paladar blando, base de lengua, hipofaringe y el avance bimaxilar. La evidencia científica demuestra en los actuales momentos que la cirugía de reconstrucción de la vía aérea compite de una manera efectiva con el tratamiento médico.Nasal continuous positive airway pressure (CPAP is considered an ideal treatment for treating Obstructive Sleep Apnea Syndrome (OSAS, due to its being conservative and reversible; however, there is a poor rate of adherence in its long-term use. Surgery can significantly complement those cases where CPAP is not tolerated. Surgery for OSAS must be carried out taking into account the degree of obstructive apnea, the place of greatest obstruction and the experience of the medical team. The more severe the OSAS, the more aggressive the surgical therapy can be. The place of obstruction must not be considered in a simplistic way, in which only one place of

Durante ambos os estados ocorre uma redução do tônus da musculatura faríngea. Identificar pacientes com AOS é importante a fim de prevenir riscos durante o período perioperatório. O objetivo deste trabalho foi apresentar uma revisão sobre a relação entre AOS e anestesia, levando em conta o planejamento da anestesia, enfatizando a importância da identificação da síndrome da apnéia e hipopnéia obstrutiva do sono (SAHOS. CONTEÚDO: A SAHOS ocorre principalmente por colapso total ou parcial da faringe, podendo levar a diminuição na saturação da oxiemoglobina e complicações cardiovasculares. Os principais fatores predisponentes são sexo masculino, obesidade, características crânio e orofaciais. Seu diagnóstico é clínico e polissonográfico, o que também quantifica a gravidade da AOS. Os pacientes com SAHOS especialmente acentuada podem apresentar problemas durante a intubação traqueal e sedação, estando alguns mais susceptíveis à ocorrência de hipóxia e hipercapnia, mesmo na vigência de pulmões normais. Os autores discutem a importância do diagnóstico prévio e tratamento da SAHOS na tentativa de reduzir o risco anestésico. CONCLUSÕES: O diagnóstico e tratamento prévio da SAHOS com pressão positiva contínua nas VAS podem reduzir complicações perioperatórias e influenciar na conduta anestésica e na recuperação pós-anestésica.JUSTIFICATIVA Y OBJETIVOS: El mantenimiento de la permeabilidad de las vías aéreas superiores (VAS es fundamental para la anestesia y para pacientes con apnea obstructiva del sueño (AOS.

    Full Text Available El síndrome de apnea-hipopnea del sueño es el más frecuente de los trastornos respiratorios que se producen durante el sueño, afectando alrededor del 4% de los adultos, y a casi 2 millones de personas en España. Se presenta con episodios repetidos de obstrucción de la vía aérea superior provocando un colapso del flujo de aire hacia los pulmones y síntomas como somnolencia diurna, trastornos respiratorios, cardiovasculares, psicológicos e intelectuales. La somnolencia al conducir es común entre conductores profesionales, afectando su rendimiento y la seguridad de la población. Se llevó a cabo una revisión bibliográfica exploratoria, para conocer la prevalencia de la patología en conductores profesionales, los factores del riesgo implicados, los métodos utilizados en su diagnóstico y su relación con los accidentes de tránsito. Se seleccionaron nueve bases de datos, PUBMED, IBECS, LILACS, COCHRANE LIBRARY, EMBASE, SCOPUS, SCIELO, WOS y WOK, para llevar a cabo la búsqueda entre Octubre 2011 y Enero 2012. Luego de aplicados los criterios de inclusión/exclusión se analizaron 12 artículos. La prevalencia del síndrome es similar en la mayoría de los estudios pero superior a la población general. Los factores de riesgo de mayor estudio e impacto fueron la obesidad, la somnolencia excesiva, los ronquidos. No existe consenso entre los test diagnósticos utilizados y su eficacia. Sin embargo el más utilizado ha sido la escala de Epworth (ESE.

    Full Text Available A apneia obstrutiva do sono (AOS é uma condição clínica comum na população em geral, principalmente entre os pacientes portadores de doenças cardiovasculares. Mais do que um fenômeno local de obstrução das vias aéreas superiores, a AOS traz repercussões sistêmicas que podem incluir a hipóxia intermitente, a redução abrupta da pressão intratorácica e a ocorrência de microdespertares com fragmentação do sono. Nas últimas décadas, inúmeras evidências apontam de forma consistente a AOS como um importante fator envolvido na ocorrência de doenças cardiovasculares. Particularmente, a relação entre a AOS e a hipertensão arterial sistêmica (HAS é a que encontra um maior conjunto de evidências. Atualmente, encontram-se dados que consideram a AOS uma importante causa secundária de HAS. Mais do que isso, a AOS está independentemente associada a um pior controle pressórico, alteração do descenso noturno da pressão arterial e à presença de lesões de órgãos-alvo, tais como a hipertrofia do ventrículo esquerdo e a microalbuminúria. Estudos randomizados sugerem que o tratamento da AOS, especialmente com a pressão positiva contínua de vias aéreas superiores (CPAP, considerado o tratamento padrão para a AOS, promove redução significante da pressão arterial nas 24 horas, efeito esse mais significante no subgrupo de pacientes com HAS não controlada e nos pacientes com HAS resistente. A despeito de todas essas evidências, a AOS ainda continua sendo subdiagnosticada. O objetivo desta revisão é discutir os recentes avanços nos mecanismos fisiopatológicos, na apresentação clínica e no tratamento da AOS, e o benefício sobre a pressão arterial.La apnea obstructiva del sueño (AOS es una condición clínica común en la población en general, principalmente entre los pacientes portadores de enfermedades cardiovasculares.

We suggest that an increase greater than 6% in REM sleep should be considered REM rebound, since 6.15 percent was the statistically significant difference between bPSG REM sleep and cPSG. The prevalence of RR in our group was 46 percent and the variables that contribute more to RR are REM sleep during bPSG, AHI at baseline and body mass index.Antecedentes. En pacientes con síndrome de apnea obstructiva del sueño (SAOS el tratamiento con CPAP produce un incremento en el sueño REM y el sueño profundo, pero no hay suficiente información acerca de la prevalencia del rebote de sueño REM en pacientes con SAOS y los posibles factores relacionados con este fenómeno.

La mayoría de los pacientes responden al tratamiento postural, en decúbito prono, puede ser necesario controlar la saturación de oxígeno, insertar un tubo nasofaríngeo e incluso intratraqueal. En casos más graves con pausas prolongadas y frecuentes de apnea, la traqueostomía puede ser necesaria, pero se asocia a una alta morbilidad y, ocasionalmente, mortalidad. En los últimos 2 años, en la Unidad Multidisciplinaria de Labio y Fisura Palatina del Hospital Virgen de las Nieves de Granada, se ha tratado a 4 niños con apnea obstructiva grave secundaria a hipoplasia mandibular grave mediante distracción mandibular osteogénica, y este procedimiento se ha mostrado eficaz en la resolución del problema. Ha evitado la traqueostomía y se ha elongado la mandíbula en el plazo de 3-4 semanas. En este tiempo han desaparecido los problemas respiratorios obstructivos, así como también de la deglución, y los resultados estéticos obtenidos han resultado excelentes y las complicaciones, por el momento, mínimas.Craniofacial malformations (Pierre-Robin sequence, Treacher-Collins syndrome, Nager syndrome, etc. are frequently accompanied by severe mandibular hypoplasia, which can cause upper airway obstruction due to retroposition of the base of the tongue in the posterior pharyngeal space.

OBJETIVO: Investigar se um diagnóstico clínico padronizado de SAOS, em pacientes com SCA, prediz o risco de eventos cardiovasculares durante hospitalização. MÉTODOS: Em um estudo de coorte prospectivo, um grupo de 200 pacientes com diagnóstico de SCA estabelecido entre Setembro de 2005 e Novembro de 2007, foram estratificados pelo Questionário de Berlim (QB para o risco de SAOS (alto ou baixo risco. Foi testado se o subgrupo de alto risco para SAOS apresenta maior tendência à eventos cardiovasculares. O endpoint primário avaliado foi um desfecho composto de morte cardiovascular, eventos cardíacos isquêmicos recorrentes, edema pulmonar agudo e acidente vascular cerebral durante a hospitalização. RESULTADOS: Noventa e quatro (47% dos pacientes identificados pelo QB apresentavam suspeita de SAOS. Alto risco para SAOS estava associado com uma mortalidade mais elevada, embora sem diferença estatística (4,25% vs 0,94%; p=0,189, mas com uma estatisticamente significante maior incidência de desfecho composto de eventos cardiovasculares (18,08% vs 6,6%; p=0,016.

Se empleó equipamiento Roscraff, caliper Slimguide y reloj Polar RS 800CX. Se evaluaron 14 pacientes candidatos a rehabilitación respiratoria: Edad 76 ± 9,9 años; IMC 26,7 ± 3,9 kg/m²; Masa Muscular 26,1 ± 6,3 kg; Masa Ósea 8,1 ± 1,3 kg; Masa Adiposa 16,4 ± 3,6 kg; VEF1 54 ± 14 %. Un mayor perímetro de cintura e índice Cintura Cadera se asoció a una menor Variabilidad del ritmo cardiaca global. El componente óseo se relacionó positivamente con la Variabilidad del ritmo cardiaco y los pacientes con un mayor Volumen espiratorio forzado en el primer segundo presentaron un menor componente de alta frecuencia en la Variabilidad del ritmo cardiaco. En estos pacientes, la Variabilidad del ritmo cardiaco en forma global se encuentra reducida y se asocia con parámetros de riesgo cardiovascular.

    Full Text Available Fundamento: la enfermedad pulmonar obstructiva crónica constituye un problema de salud pública de enorme magnitud, lo cual no ha pasado inadvertido en el Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos. Objetivo: evaluar el proceso de aplicación de un instrumento para la estratificación del paciente con enfermedad pulmonar obstructiva crónica asistido en el Departamento de Urgencias. Métodos: el instrumento fue aplicado a 192 pacientes ingresados y egresados de la institución con diagnóstico de enfermedad pulmonar obstructiva crónica descompensada, en el periodo comprendido entre mayo de 2010 y abril de 2011; en la evaluación fueron utilizados varios indicadores de proceso y de resultado. Resultados: la utilización del instrumento se convirtió en una acción médica rápidamente incorporada y sistemáticamente empleada, aunque no se acompañó de mejoría progresiva en la calidad de la estratificación. El predominio de pacientes en la clase de riesgo elevado de desenlace adverso y altas probabilidades de recuperación estuvo determinado por un elevado número de pacientes con descompensación moderada y asociación a neumonía o insuficiencia cardiaca, los cuales en su mayoría fueron estratificados como riesgo moderado e ingresados en sala de Medicina, a pesar de lo cual la letalidad en ellos fue relativamente baja, al igual que la frecuencia de traslados a Unidades de Cuidados Intensivos de los pacientes inicialmente admitidos en sala (10 %. Conclusiones: los resultados obtenidos en el comportamiento de la letalidad y del índice de traslado a UCI sugieren la conveniencia de realizar modificaciones al instrumento de estratificación utilizado.

    Full Text Available Objetivo: En este trabajo se presenta la aplicación del análisis coste-efectividad de tipo probabilístico al tratamiento con presión continua en la vía respiratoria por vía nasal (nasal continuous positive airway pressure, nCPAP del síndrome de la apnea obstructiva del sueño (SAOS. Material y métodos: La base del estudio es un modelo de Markov probabilístico. Éste se caracteriza porque las variables se introducen en forma de distribuciones. El modelo se procesa mediante 2.000 simulaciones de Monte Carlo, cada una de las cuales calcula el coste y la efectividad incrementales. El resultado se analiza mediante el plano coste-efectividad, la curva de aceptabilidad, el beneficio neto y el valor esperado de la información perfecta. Resultados: La razón coste-efectividad del tratamiento con nCPAP media calculada es de 5.480 S/año de vida ajustado por calidad (AVAC. Utilizando como umbral de eficiencia la cifra de 30.000 €/AVAC, el análisis probabilístico muestra que en el 98,5% de las simulaciones el tratamiento con nCPAP es una práctica eficiente. El valor esperado de la información perfecta muestra que el parámetro que origina más incertidumbre en el resultado es la ganancia en calidad de vida producida por el tratamiento. Conclusiones: El análisis de tipo probabilístico ratifica el resultado de los estudios deterministas que caracterizan el tratamiento con nCPAP como una intervención eficiente. La ventaja añadida es que permite situar la incertidumbre en términos cuantitativos; en este caso la probabilidad de equivocarse es inferior al 5%. Además, el estudio muestra que para reducir esa incertidumbre la investigación debe centrarse en la mejora de la información referente a la calidad de vida.Objective: To describe the application of a probabilistic cost-effectiveness analysis to nasal continuous positive airway passage (nCPAP treatment of obstructive sleep apnea syndrome (OSAS.

    Full Text Available El síndrome de apnea obstructiva del sueño (SAOS constituye en la actualidad un problema de salud importante, tanto por su prevalencia como por la morbilidad que provoca sobre el aparato cardiovascular y la calidad de vida del paciente. Actualmente, la base del tratamiento es la administración de presión positiva continua durante el sueño (CPAP que, si bien tiene una elevada eficacia, no es tolerada en muchos casos. Los tratamientos quirúrgicos han sido variados. En un principio se centraron en el sistema velofaríngeo con mejorías no superiores al 50% a largo plazo. En nuestro planteamiento terapéutico identificamos, mediante pruebas funcionales y de imagen, las regiones implicadas en cada caso. Entre ellas destaca la base de la lengua. La técnica que presentamos constituye una modificación a las ya descritas para el avance de la base lingual. Consiste en una fijación controlada de la misma a la cortical vestibular de la mandíbula con un punto de hilo de monofilamento pasado a través de dos orificios, sin necesidad de aditamentos especiales. Conseguimos una estabilización permanente con buenos resultados clínicos y polisomnográficos a largo plazo. Las complicaciones estuvieron en relación con problemas deglutorios en el postoperatorio inmediato.Sleep apnoea síndrome constitutes an important health problem because of its prevalence and impact over the cardiovascular system and quality of life of the patient. The classic conservative treatment remains to be the CPAP. Although it has a high efficacy, it is not well tolerated by the patient in many cases. The surgical treatments were initially devoted to the velopharyngeal complex, being definitive in only 50% of the cases. Our therapeutical approach consists on a thorough examination of the different areas affected in every case, one of which is the tongue base. The surgical technique we present constitutes a modification of others already described to advance the tongue base. It

    Full Text Available La enfermedad pulmonar obstructiva crónica es la patología crónica respiratoria más frecuente y que con más frecuencia puede producir incapacidad. La manera tradicional de evaluar la gravedad de la enfermedad es mediante la espirometría. Pero la presentación clínica de la enfermedad no es homogénea y se conoce que no hay una buena correlación entre los resultados de la espirometría y la situación clínica real del enfermo. En los últimos años se han desarrollado procedimientos para evaluar la enfermedad combinando varios parámetros, o sea haciendo una evaluación multidimensional. Esto consigue predecir mucho mejor el pronóstico y la gravedad de la patología. Los médicos que hacemos evaluación de la incapacidad debemos conocer y manejar estas herramientas para hacer nuestras valoraciones más precisas. Se presentan dos de estas herramientas la derivada de la Iniciativa GOLD y la desarrollada en España, la GesEPOC. Se explica su aplicación y su uso en la evaluación de la incapacidad.

    Full Text Available La enfermedad pulmonar obstructiva crónica se ha convertido en una de las enfermedades crónicas atendidas con mayor frecuencia en la atención primaria de salud. Produce altas tasas de morbilidad y mortalidad en todo el mundo, con una evolución lenta aunque progresivamente mortal, a pesar de tratarse de una enfermedad prevenible, que depende en gran medida, del hábito de fumar. La prevalencia variará según el consumo de tabaco, y se espera que siga aumentando en los próximos 25 años. La mortalidad y morbilidad son cada vez mayores, lo que supone un enorme gasto sanitario, social y personal, pero es una enfermedad potencialmente modificable, motivo por el que requiere de un abordaje multifactorial.Chronic Obstructive Pulmonary Disease has become one of the most frequently treated chronic diseases in primary health care. High rates of morbidity and mortality are worldwide related to this disease. Although it is a preventable disease closely related to smoking, its evolution is slow but progressively fatal. Prevalence varies according to tobacco consumption and is expected to increase in the next 25 years. Even when it is a potentially modifiable disease, mortality and morbidity are also increasing, causing a major health, social and personal spending. For all these reasons, a multifactorial approach is needed both, for health and social issues.

Objetivo. Evaluar el uso de dos esquemas de esteroides, en comparación con el tratamiento convencional, en exacerbaciones agudas no acidóticas de la enfermedad pulmonar obstructiva crónica. Material y métodos. Ciento seis pacientes de la Clínica Carlos Lleras Restrepo de Bogotá, con diagnóstico de enfermedad pulmonar obstructiva crónica exacerbada se evaluaron, siendo distribuidos en tres grupos: a Tratamiento convencional, b Hidrocortisona más esquema convencional y c Prednisolona más esquema convencional. Se valoró a las 72 horas el cambio porcentual en la medición del flujo-pico, la variación auscultatoria pulmonar y la percepción de mejoría clínica. Además, se consignó la estancia hospitalaria, la necesidad de tratamientos adicionales o ventilación mecánica y efectos colaterales. Resultados. No se encontraron diferencias significativas en la respuesta a los tres esquemas terapéuticos, salvo una mejor percepción subjetiva con la hidrocortisona. En el análisis por subgrupos la prednisona oral disminuyó la estancia hospitalaria, mejoró el flujo-pico espiratorio y la percepción subjetiva de síntomas en pacientes mayores de 80 años, con VEF1 menor o igual a 50% del predicho y que cursaron con una exacerbación severa. El género, la clase funcional basal, la causa y el tipo de la descompensación, el número de exacerbaciones-año y el número de paquetes-año, no influyeron en la respuesta a los tres grupos. El efecto secundario más frecuente con esteroides fue la hiperglicemia. Conclusión. Los esteroides sistémicos en forma global, no son mejores que el tratamiento convencional en exacerbaciones de EPOC. Sin embargo, la prednisona oral mejoró objetiva y subjetivamente las exacerbaciones severas, en los

    Introduccion. El sindrome de apnea/hipopnea obstructiva del sueño (SAHOS) confiere mayor riesgo de enfermedad cardiovascular, dada su asociacion con otros factores de riesgo vascular. Tanto el SAHOS como otros factores de riesgo vascular se asocian con lesiones cerebrales silentes. Objetivo. Evaluar la prevalencia de lesiones cerebrales silentes en pacientes con SAHOS. Pacientes y metodos. Se evaluo retrospectivamente una cohorte de 137 pacientes con SAHOS, con una edad media de 65 ± 12 años, el 45% mujeres. Las lesiones cerebrales silentes en resonancia magnetica se evaluaron con la escala visual de Fazekas, y se consigno la presencia de infartos corticales, lacunares y microsangrados. Resultados. La prevalencia de factores de riesgo vascular fue: hipertension, 64%; dislipidemia, 58%; diabetes, 18%; tabaquismo, 34%; ateromatosis carotidea, 26%; enfermedad coronaria, 13%; y fibrilacion auricular, 4%. El SAHOS fue leve en el 47%, moderado en el 31% y grave en el 22% de los casos. El 91% de los pacientes tenia hiperintensidades periventriculares y el 66% presentaba lesiones en la sustancia blanca subcortical. El valor medio del indice de apnea/hipopnea fue mayor en los pacientes con mayor carga de lesiones, aunque sin significacion estadistica. Conclusiones. Los pacientes con SAHOS presentan una elevada prevalencia de lesiones cerebrales silentes, fundamentalmente con un patron microangiopatico. Posiblemente esto se explique por la asociacion entre el SAHOS, la hipertension arterial y otros factores de riesgo vascular.

    Full Text Available La disnea y la disminución de la capacidad de realizar ejercicio son los principales factores que limitan las actividades de la vida diaria en pacientes con enfermedades respiratorias crónicas. Los síntomas cardinales que limitan la capacidad de ejercicio en la mayoría de los pacientes con enfermedad pulmonar obstructiva crónica (EPOC son la disnea y/o fatigabilidad, los cuales pueden ser ocasionados por trastornos de la ventilación alveolar e intercambio gaseoso, disfunción de los músculos esqueléticos y/o falla cardiovascular. La ansiedad, falta de motivación y depresión también han sido asociadas a una menor capacidad de realizar ejercicio, probablemente afectando la percepción de los síntomas. La relación entre el estado psicológico y los trastornos del ánimo en pacientes con EPOC y la tolerancia al ejercicio es compleja y aún no ha sido completamente dilucidada. El origen de la limitación de la capacidad de ejercicio en pacientes con EPOC es multifactorial, por lo cual la separación de las variables involucradas con fines académicos no siempre es factible realizarlo en los pacientes. Los mecanismos patogénicos pueden relacionarse en forma compleja, a modo de ejemplo, el desacondicionamiento físico y la hipoxemia pueden contribuir a aumentar la ventilación alveolar ocasionando limitación del ejercicio de causa ventilatoria. Por lo tanto, el entrenamiento físico y el suplemento de oxígeno pueden reducir la limitación ventilatoria durante el ejercicio sin modificar la función pulmonar o la capacidad ventilatoria máxima. El análisis de los factores limitantes de la capacidad de ejercicio permite identificar trastornos potencialmente reversibles que pueden mejorar la calidad de vida de los enfermos, tales como la hipoxemia, broncoespasmo, insuficiencia cardiaca, arritmias, disfunción musculoesquelética y/o isquemia miocárdica.

    Full Text Available Asma y enfermedad pulmonar obstructiva crónica (EPOC son enfermedades pulmonares comunes con semejanzas y diferencias. Estudios genéticos recientes han dado información importante acerca de los múltiples loci susceptibles para cada enfermedad. Estudios del genoma han mostrado resultados similares en al menos una región cromosomal en ambas enfermedades, así como también evidencia de la interacción con factores ambientales (por ejemplo, el fumado activo en los pacientes con EPOC, o el pasivo en aquellos con asma. Existen pocos estudios recientes acerca del remodelamiento de la vía aérea y su importancia en pacientes asmáticos persistentes crónicos, lo que podría explicar de cierta forma la progresión de estas personas a enfermedades pulmonares obstructivas crónicas.

    Full Text Available El tratamiento que ha demostrado mayor eficacia en los pacientes con síndrome de apneas-hipopneas del sueño (SAHS es la presión positiva continua de la vía aérea (CPAP. Los mayores inconvenientes son la incomodidad y la sensación de claustrofobia, que en algunos pacientes provoca rechazo o intolerancia. Una alternativa son los dispositivos de avance mandibular (DAM, que insertados en las arcadas dentarias producen el avance de la mandíbula y de la lengua, aumentando el volumen de la vía aérea. Objetivo: Presentar nuestra experiencia en el tratamiento del SAHS mediante dispositivos de avance mandibular tipo Herbst. Metodología: Estudio de seguimiento prospectivo desde junio de 2006 hasta enero de 2009 de 7 pacientes del Área Hospitalaria Virgen Macarena con SAHS que rechazan el tratamiento con CPAP y a los que se ofrece tratamiento con DAM. Las variables analizadas son: índice de apneas-hipopneas por hora, índice de desaturaciones por hora, intensidad subjetiva del ronquido y el test de somnolencia de Epworth, antes del tratamiento y al menos 6 meses después desde el inicio de su uso. Utilizamos el test de Wilcoxon para detectar diferencias estadísticas significativas (pThe most effective treatment in patients with sleep apnea-hypopnea syndrome (SAHS is CPAP (continuous positive airway pressure. The main drawback of CPAP is the discomfort and claustrophobic sensation that it causes, which elicits rejection or intolerance by some patients. A non-surgical alternative to CPAP is the mandibular advancement device (MAD, which consists of a plastic splint inserted between the dental arches to shift the jaw and tongue forward and thus increase airway volume.

    Full Text Available Las enfermedades del sueño se clasifican en disomnias, parasomnias, enfermedades del sueño asociadas con enfermedades médicas y psiquiátricas, y las propuestas enfermedades del sueño. Solo las parasomnias han sido estudiadas como tales en el recién nacido. Las parasomnias que ocurren en el recién nacido son el síndrome de apnea infantil del sueño, el síndrome de hipoventilación congénita central, el síndrome de muerte infantil súbita, y el mioclono neonatal benigno del sueño. Bajo el término de síndrome de apnea infantil del sueño se agrupan tres entidades: (1 el síndrome de apnea del prematuro, (2 el síndrome de evento que pone en peligro la vida del niño asociado con apnea, y (3 la apnea obstructiva del sueño. El síndrome de hipoventilación central congénito puede estar asociado a otras enfermedades del sistema autónomo tales como la enfermedad de Hirschsprung (síndrome de Haddad y la dismotilidad esofágica, y a tumores del sistema nervioso simpático, especialmente al neuroblastoma. La implementación de la posición supina para dormir y el no fumar en los hogares ha disminuido la frecuencia del síndrome de muerte súbita infantil a 0.85 por 1.000 nacimientos. El mioclono neonatal benigno del sueño debe considerarse en todo recién nacido con un examen normal entre los episodios de mioclonia cuyos episodios sólo ocurren durante el sueño. Esta entidad puede confundirse con status epilepticus, porque los eventos pueden asociarse a aumentos de la frecuencia cardíaca. El uso de las benzodiazepinas puede prolongar la duración de los eventos mioclónicos.Sleep disorders are classified in dyssomnias, parasomnias, sleep disorder associated with medical and psychiatric disorders and proposed sleep disorders. Only the parasomnias have been studied as such in the newborn period.

    2015-01-01

    Clinical evidence has established that sleep apnea is a risk factor for stroke. Patients with stroke have a high prevalence of sleep apnea that may have preceded or developed as a result of the stroke. Well-established concurrent stroke risk factors for stroke like hypertension and atrial fibrillation respond favorably to the successful treatment of sleep apnea. The gold standard diagnosis of sleep apnea is obtained in the sleep laboratory, but unattended polysomnography is gaining acceptance. Positive airway pressure (PAP) (continuous positive airway pressure [CPAP] or bilevel positive airway pressure [BiPAP]) applications are the gold-standard treatment of sleep apnea. Suggestive evidence indicates that stroke occurrence or recurrence may be reduced with treatment of sleep apnea. PMID:25407131

The driving forces in the pathophysiology are felt to be ventilator instability associated oscillation in PaCO2 arterial partial pressure of Carbon Dioxide, continuous cositive airway pressure (CPAP related increased CO2 carbon dioxide elimination, and activation of airway and pulmonary stretch receptors triggering these central apneas. The prevalence ranges from 0.56% to 18% with no clear predictive characteristics as compared to simple obstructive sleep apnea. Prognosis is similar to obstructive sleep apnea. The central apnea component in most patients on followup using CPAP therap, has resolved. For those with continued central apneas on simple CPAP therapy, other treatment options include bilevel PAP, adaptive servoventilation, permissive flow limitation and/or drugs.

    Full Text Available En este artículo se discute la relación existente entre la enfermedad pulmonar obstructiva crónica (EPOC y el humo de biomasa. Más de la mitad de la población utiliza biomasa como combustible principal, sobre todo en áreas rurales y en países en vías de desarrollo donde su uso llega hasta el 80%. La inhalación del humo de biomasa crea un estado inflamatorio crónico, que se acompaña de una activación de metaloproteinasas y una reducción de la movilidad mucociliar. Esto podría explicar la gran asociación existente entre la exposición a biomasa y EPOC, revelada por estudios observacionales y epidemiológicos provenientes de países en vías de desarrollo y de países desarrollados. En esta revisión exploramos también las diferencias entre la EPOC causada por tabaco y por biomasa, y encontramos que, a pesar de las diferencias fisiopatológicas, la mayoría de las características clínicas, calidad de vida y mortalidad fueron parecidas. En los últimos diez años se han realizado intervenciones para disminuir la exposición a biomasa mediante el uso de cocinas mejoradas y combustibles limpios, sin embargo, estas estrategias todavía no han sido exitosas debido a su incapacidad para reducir los niveles de contaminación a niveles recomendados por la Organización Mundial de la Salud, y por su falta de uso. Por lo tanto, hay una necesidad urgente de ensayos de campo aleatorios, cuidadosamente realizados, para determinar la verdadera gama de reducciones de contaminación potencialmente alcanzables, la probabilidad de su uso y los beneficios a largo plazo en la reducción de la gran carga mundial de EPOC

    Full Text Available El síndrome de apneas-hipoapneas del sueño, en lo adelante (SAHS es una alteración que actualmente afecta a un número elevado de niños y adolescentes. Esta revisión tiene como objetivo evaluar los factores que generan esta alteración y el riesgo de padecer otro tipo de enfermedad asociada al SAHS. Los artículos seleccionados para ser incluidos en esta revisión se identificaron a través de GOOGLE SCHOLAR con un total de 50 artículos. La validez de los artículos estuvo dada por el grado de evidencias demostrado, por las recomendaciones que dejan y por la aplicabilidad a nuestro contexto. Esta revisión ha considerado los estudios que investigan el SAHS en niños y adolescentes. También se han tenido en cuenta los que relacionan esta alteración con la obesidad, la hipertensión arterial, la actividad física y otras variables. Los estudios demuestran que el SAHS está relacionado con la obesidad infantil y aumenta el riesgo de enfermedades cerebrocardiovascular. También se evidencia que disminuye la capacidad física y la calidad de vida de niños y adolescentes. Los aspectos psicológicos también se ven afectados, lo que influye en el rendimiento académico, que es inferior al de los niños sanos. Así pues, es importante un diagnóstico precoz del SAHS pediátrico, de modo que se eviten las alteraciones asociadas.

    Full Text Available Apnea of prematurity (AOP is one of the most frequent pathologies in the Neonatal Intensive Care Unit, with an incidence inversely related to gestational age. Its etiology is often multi factorial and diagnosis of idiopathic forms requires exclusion of other underlying diseases. Despite being a self-limiting condition which regresses with the maturation of the newborn, possible long-term effects of recurring apneas and the degree of desaturation and bradycardia who may lead to abnormal neurological outcome are not yet clarified. Therefore AOP needs careful evaluation of its etiology and adequate therapy that can be both pharmacological and non-pharmacological. Proceedings of the 9th International Workshop on Neonatology · Cagliari (Italy · October 23rd-26th, 2013 · Learned lessons, changing practice and cutting-edge research

    Sleep-induced apnea and disordered breathing refers to intermittent, cyclical cessations or reductions of airflow, with or without obstructions of the upper airway (OSA). In the presence of an anatomically compromised, collapsible airway, the sleep-induced loss of compensatory tonic input to the upper airway dilator muscle motor neurons leads to collapse of the pharyngeal airway. In turn, the ability of the sleeping subject to compensate for this airway obstruction will determine the degree o...

La BA se caracteriza por la inflamación del árbol bronquial que afecta tanto a adultos como a niños sin enfermedades pulmonares crónicas, siendo de origen viral en la mayoría de los casos. El diagnóstico es clínico, debiéndose diferenciar de los episodios de neumonía adquirida en la comunidad. El tratamiento de los episodios de BA es fundamentalmente sintomático. En huéspedes inmunocomprometidos, con enfermedades crónicas respiratorias o cardíacas y en adultos mayores con comorbilidades debe evaluarse el requerimiento de tratamiento antibiótico caso por caso. Se define como exacerbación de la EPOC al cambio agudo en la situación clínica basal del paciente más allá de la variabilidad diaria, que cursa con aumento de la disnea, aumento de la expectoración, expectoración purulenta, o cualquier combinación de estos tres síntomas, y que precisa un cambio terapéutico. La presencia de uno de estos síntomas se define como episodio leve, dos como moderado y tres como grave. En un 50 a 75% de las exacerbaciones de EPOC se aísla en el esputo un agente infeccioso. En los episodios moderados y graves debe iniciarse tratamiento antibiótico. Amoxicilina-inhibidor de betalactamasas, macrólidos y fluoroquinolonas se encuentran entre las opciones terapéuticas.

    Full Text Available Obstructive sleep apnea (OSA affects millions of Americans and is estimated to be as prevalent as asthma and diabetes. Given the fact that obesity is a major risk factor for OSA, and given the current global rise in obesity, the prevalence of OSA will increase in the future. Individuals with sleep apnea are often unaware of their sleep disorder. It is usually first recognized as a problem by family members who witness the apneic episodes or is suspected by their primary care doctor because of the individual’s risk factors and symptoms. The vast majority remain undiagnosed and untreated, despite the fact that this serious disorder can have significant consequences. Individuals with untreated OSA can stop breathing hundreds of times a night during their sleep. These apneic events can lead to fragmented sleep that is of poor quality, as the brain arouses briefly in order for the body to resume breathing. Untreated, sleep apnea can have dire health consequences and can increase the risk of hypertension, diabetes, heart disease, and heart failure. OSA management has also become important in a number of comorbid neurological conditions, including epilepsy, stroke, multiple sclerosis, and headache. Diagnosis typically involves use of screening questionnaires, physical exam, and an overnight polysomnography or a portable home study. Treatment options include changes in lifestyle, positive airway pressure, surgery, and dental appliances.

  7. Videoradiography at submental electrical stimulation during apnea in obstructive sleep apnea syndrome

    International Nuclear Information System (INIS)

    Percutaneous submental electrical stimulation during sleep may be a new therapeutic method for patients with obstructive sleep apnea syndrome (OSAS). Electrical stimulation to the submental region during obstructive apnea is reported to break the apnea without arousal and to diminish apneic index, time spent in apnea, and oxygen desaturation. The mode of breaking the apnea by electrical stimulation has not yet been shown. However, genioglossus is supposed to be the muscle responsible for breaking the apnea by forward movement of the tongue. To visualize the effect of submental electrical stimulation, one patient with severe OSAS has been examined with videoradiography. Submental electrical stimulation evoked an immediate complex muscle activity in the tongue, palate, and hyoid bone. This was followed by a forward movement of the tongue which consistently broke obstructive apnea without apparent arousal. Time spent in apnea was diminished but intervals between apnea were not affected. (orig.)

    Full Text Available Apnea test is a crucial requirement for determining the diagnosis of brain death (BD. There are few reports considering clinical complications during this procedure. We describe a major complication during performing the apnea test. We also analyse their practical and legal implications, and review the complications of this procedure in the literature. A 54 year-old man was admitted for impaired consciousness due to a massive intracerebral hemorrhage. Six hours later, he had no motor response, and all brainstem reflexes were negative. The patient fulfilled American Academy of Neurology (AAN criteria for determining BD. During the apnea test, the patient developed pneumothorax, pneumoperitoneum, and finally cardiac arrest. Apnea test is a necessary requirement for the diagnosis of brain death. However, it is not innocuous and caution must be take in particular clinical situations. Complications during the apnea test could be more frequent than reported and may have practical and legal implications. Further prospective studies are necessary to evaluate the frequency and nature of complications during this practice.El test de apnea (AT es un requerimiento esencial para el diagnóstico de muerte encefálica.

    Full Text Available El asma bronquial y la enfermedad pulmonar obstructiva crónica son dos problemas mayores de salud: su incidencia se encuentra en aumento y representan, indiscutiblemente, una causa importante de morbilidad y mortalidad a nivel mundial. Los glucocorticoides se han posicionado como la droga de elección en el tratamiento de padecimientos inmunológicos e inflamatorios crónicos, como el asma bronquial y la enfermedad obstructiva crónica. Estas drogas suprimen la inflamación en múltiples vías moleculares, característica que les confiere destacada eficacia. Su principal acción en dosis terapéuticas se produce por la transrepresión de genes inflamatorios activos, mediante el reclutamiento y actividad de la enzima histona-desacetilasa-2 y la remodelación de la cromatina. En dosis altas, funcionan más bien como transactivadores, acetilando las histonas y estimulando la transcripción de genes antinflamatorios, y potencialmente, también de varios genes relacionados con efectos secundarios. Además, se les reconoce acciones postranscripcionales, que modifican la estabilidad de secuencias de ARN mensajero. A pesar de esto, una respuesta disminuida a los glucocorticoides se presenta en pacientes con asma severa, en asmáticos que fuman y en quienes tienen enfermedad pulmonar obstructiva crónica. Varios mecanismos moleculares de resistencia a glucocorticoides han sido identificados. Se están investigando otros tratamientos antinflamatorios que permitan controlar los síntomas de estos pacientes, así como drogas que puedan revertir los mecanismos moleculares de la resistencia. Problemáticamente, estas terapias podrían ser demasiado específicas para resultar eficaces, como es el caso de los esteroides disociados, en el que es difícil separar efectos antinflamatorios y secundarios.

    Hernandez, Adam B; Patil, Susheel P

    2016-05-01

    The transition from wake to sleep is accompanied by a host of physiologic changes, which result in major alterations in respiratory control and may result in sleep-related breathing disorders. The central sleep apneas are a group of sleep-related breathing disorders that are characterized by recurrent episodes of airflow reduction or cessation due to a temporary reduction or absence of central respiratory drive. The fundamental hallmark of central sleep apnea (CSA) disorders is the presence of ventilatory control instability; however, additional mechanisms play a role in one or more specific manifestations of CSA. CSA may manifest during conditions of eucapnia/hypocapnia or chronic hypercapnia, which is a useful clinical classification that lends understanding to the underlying pathophysiology and potential therapies. In this review, an overview of normal breathing physiology is provided, followed by a discussion of pathophysiologic mechanisms that promote CSA and the mechanisms that are specific to different manifestations of CSA.

    Full Text Available BACKGROUND: Obstructive sleep apnea (OSA is a common disorder that affects both quality of life and cardiovascular health. The causal link between OSA and cardiovascular morbidity/mortality remains elusive. One possible explanation is that repeated episodes of nocturnal hypoxia lead to a hypercoagulable state that predisposes patients to thrombotic events. There is evidence supporting a wide array of hematological changes that affect hemostasis (eg, increased hematocrit, blood viscosity, platelet activation, clotting factors and decreased fibrinolytic activity.

    Full Text Available Los pacientes con enfermedad pulmonar obstructiva crónica (EPOC tienen debilidad de los músculos respiratorios, lo cual contribuye a la disnea, hipoxemia, hipercapnia, desaturación nocturna y limitación de la actividad física. Durante el ejercicio se ha demostrado que aumenta el trabajo del diafragma en pacientes con EPOC y utilizan una mayor proporción de la presión inspiratoria máxima (PImax comparado con los sujetos sanos. Elpatrón respiratorio anormal de los pacientes con EPOC está relacionado con la sensación de disnea durante el ejercicio y, potencialmente, podría inducir a la fatiga muscular respiratoria. Sin embargo, la fatiga del diafragma no se ha demostrado después de un ejercicio intenso. Los estudios en pacientes con EPOC han demostrado cambios adaptativos en las fibras musculares del diafragma que tienen mayor capacidad oxidativa y resistencia a la fatiga. De este modo, existen argumentos contradictorios en relación al beneficio clínico obtenido con el entrenamiento de los músculos inspiratorios (EMI en pacientes con EPOC. El EMI aislado o como complemento de ejercicios de reacondicionamiento general aumenta significativamente la fuerza muscular inspiratoria y la resistencia a la fatiga, disminuyendo significativamente la disnea en reposo y durante el ejercicio. Además, los estudios sugieren que el EMI tiende a mejorar la capacidad funcional para realizar ejercicio, efecto favorable que no alcanzó significación estadística. El análisis de subgrupos ha demostrado mayor beneficio clínico del EMI en los pacientes con debilidad muscular inspiratoria. De esta revisión se concluye que el entrenamiento muscular inspiratorio puede ser útil en pacientes seleccionados con enfermedad pulmonar obstructiva crónica, que tienen disfunción muscular inspiratoria comprobada, insertado en un programa de rehabilitación integral.

    Full Text Available No abstract available. Article truncated at 150 words. A common conundrum faced by sleep medicine practitioners is how to manage the large group of patients with mild sleep apnea. Many patients are referred for sleep evaluation, with symptoms thought to be due to obstructive sleep apnea (OSA. Often polysomnography demonstrates only mild sleep apnea, and the clinician and patient are faced with the dilemma of whether to use continuous positive airway pressure (CPAP therapy or an oral appliance. In making this important decision the clinician incorporates the commonly used definition of mild sleep apnea as an apnea-hypopnea index of between 5 and 14 apneas or hypopneas per hour of sleep. Moderate sleep apnea is defined as 15-29 events per hour, and severe is 30 and above events per hour. These arbitrary thresholds originated in the early 1980s when knowledge of this condition was in its infancy and little was known about the long term health effects. The definition ...

    Full Text Available The mucopolysaccharidoses (MPSs are a group of inherited, metabolic disorders characterized by progressive multisystem accumulation of partially degraded glycosaminoglycans. This manifests with multilevel airway obstruction, presenting with obstructive sleep apnea (OSA. We systematically reviewed the literature to determine the severity and prevalence of OSA in MPS based on polysomnography analysis. Fifteen studies with 294 participants met the inclusion criteria for review. The pretreatment prevalence of OSA in MPS was 81% with a mean apnea–hypopnea index (AHI of 10.4. Patients with MPS I are most significantly affected, with 75% suffering with moderate to severe OSA (mean AHI, 16.6. Enzyme replacement therapy (ERT results in an almost significant reduction in OSA in MPS I (P = .06, while adenotonsillar surgery significantly improves AHI (P = .002.

    Surgical management of snoring and obstructive sleep apnea is indicated when a surgically correctable abnormality is believed to be the source of the problem. Many patients opt for surgical treatment after noninvasive forms of treatment have been proven ineffective or difficult to tolerate. With increasing frequency, functional rhinoplasty, septoplasty, turbinoplasty, palatal surgery, and orthognathic surgery are being used in the management of snoring and obstructive sleep apnea. Plastic surgeons' experience with aesthetic nasal surgery, nasal reconstruction, palatal surgery, and craniofacial surgery puts them at the forefront of performing surgery for snoring and sleep apnea. The role of functional septorhinoplasty, turbinoplasty, palatal surgery, genioglossal advancement, and orthognathic surgery is indispensable in the surgical management of obstructive sleep apnea. Multidisciplinary management of these patients is critical, and plastic surgeons are encouraged to work collaboratively with sleep medicine clinicians and centers. PMID:27018680

    Central sleep apnea (CSA) is a disease characterized by repetitive episodes of the socalled central apneas during sleep. The disease has a very complex etiology. In clinical practice, the most important causes of CSA are disorders of the central nervous system, congestive heart failure or certain pathological changes of the respiratory muscles. We present a case of a 43-year-old male with severe CSA, who was successfully treated with BiPAP ST equipment.

    Objective:To get a comprehensive understanding about the relationship between obstructive sleep apnea (OSA) and asthma by reviewing the epidemiology,pathophysiology,and clinical manifestation and then summarizing the latest progress on diagnosis and treatment.Data Sources:Articles referred in this review were mainly collected from a comprehensive search of the PubMed published in English from 1990 to 2015 with the terms "OSA" and “asthma'" as the main keywords.Highly regarded older publications were also included.Study Selection:Information about the features of the two diseases in common,the pathophysiologic association between them and their current treatments from the literature search were identified,retrieved,and summarized.Results:Both OSA and asthma are very prevalent conditions.The incidences of them have kept on rising in recent years.Asthma is often accompanied by snoring and apnea,and OSA often combines with asthma,as well.They have many predisposing and aggravating factors in common.Possible shared direct mechanistic links between them include mechanical effects,intermittent hypoxia,nerve reflex,inflammation,leptin,etc.Indirect mechanistic links include medication,nose diseases,smoking,obesity,and gastroesophageal reflux disease.Since OSA presents many similar features with nocturnal asthma,some scholars termed them as a sole syndrome "alternative overlap syndrome,"and proved that asthma symptoms in those patients could be improved through the treatment of continuous positive airway pressure.Conclusions:OSA and asthma are closely associated in pathogenesis,symptoms,and therapies.With the growing awareness of the relationship between them,we should raise our vigilance on the coexistence of OSA in those difficult-to-control asthmatic patients.Further studies are still needed to guide the clinical works.

    Bloch, Konrad E., Tsogyal D. Latshang, and Silvia Ulrich. Patients with obstructive sleep apnea at altitude. High Alt Med Biol 16:110-116, 2015.--Obstructive sleep apnea (OSA) is highly prevalent in the general population, in particular in men and women of older age. In OSA patients sleeping near sea level, the apneas/hypopneas associated with intermittent hypoxemia are predominantly due to upper airway collapse. When OSA patients stay at altitudes above 1600 m, corresponding to that of many tourist destinations, hypobaric hypoxia promotes frequent central apneas in addition to obstructive events, resulting in combined intermittent and sustained hypoxia. This induces strong sympathetic activation with elevated heart rate, cardiac arrhythmia, and systemic hypertension. There are concerns that these changes expose susceptible OSA patients, in particular those with advanced age and co-morbidities, to an excessive risk of cardiovascular and other adverse events during a stay at altitude. Based on data from randomized trials, it seems advisable for OSA patients to use continuous positive airway pressure treatment with computer controlled mask pressure adjustment (autoCPAP) in combination with acetazolamide during an altitude sojourn. If CPAP therapy is not feasible, acetazolamide alone is better than no treatment at all, as it improves oxygenation and sleep apnea and prevents excessive blood pressure rises of OSA patients at altitude.

  17. Obstructive sleep apnea and inflammation.

    McNicholas, Walter T

    2012-02-01

    The pathogenesis of cardiovascular complications in obstructive sleep apnea syndrome (OSAS) is not fully understood but is likely multifactorial in origin. Inflammatory processes play an important role in the pathogenesis of atherosclerosis, and circulating levels of several markers of inflammation have been associated with future cardiovascular risk. These include cell adhesion molecules such as intercellular adhesion molecule-1 and selectins, cytokines such as tumour necrosis factor alpha and interleukin 6, chemokines such as interleukin 8, and C-reactive protein. There is also increasing evidence that inflammatory processes play an important role in the cardiovascular pathophysiology of OSAS and many of the inflammatory markers associated with cardiovascular risk have been reported as elevated in patients with OSAS. Furthermore, animal and cell culture studies have demonstrated preferential activation of inflammatory pathways by intermittent hypoxia, which is an integral feature of OSAS. The precise role of inflammation in the development of cardiovascular disease in OSAS requires further study, particularly the relationship with oxidative stress, metabolic dysfunction, and obesity.

    Previous case reports have shown an association between acromegaly and the sleep apnea syndrome (SAS). Some of the patients described had central SAS, raising the possibility that an elevation of the growth hormone (GH) level may cause a defect in respiratory drive. We determined the prevalence of SAS in 21 patients with a history of acromegaly. We separated them into two groups based on serum GH concentrations. Ten patients had active acromegaly (mean GH concentration, 62.2 ng/mL; range, 12.6 to 148 ng/mL), while 11 patients had inactive acromegaly (mean GH, 3.2 ng/mL; range, 0.7 to 6.4 ng/mL). Four of the ten patients with active acromegaly had SAS; none of the 11 patients with inactive acromegaly had SAS. Three patients with SAS had the purely obstructive type, and one had the mixed central and obstructive type. The hypercapnic ventilatory response was normal in all patients tested and was not influenced by the GH level. We conclude that SAS is associated with active acromegaly and that the GH level does not affect the hypercapnic ventilatory response. The absence of SAS in successfully treated patients suggests that it may resolve after a normal GH level is restored.

    Full Text Available Obstructive Sleep Apnea (OSA is an important public health problem and is associatedwith considerable morbidity and mortality. Therefore, treatment of this condition is ofparamount importance. The treatment of OSA includes general and behaviouralmeasures, mechanical measures including continuous positive airway pressure(CPAP, Bilevel positive airway pressure (BiPAP and Oral Appliances (OA,pharmacological treatment and surgical procedures. Continuous positive airwaypressure (CPAP treatment reverses the repetitive upper airway obstruction of sleepapnea and associated daytime sleepiness and is the most effective treatment for OSA.However maintaining patient adherence to CPAP therapy is a challenge. Weight lossshould be recommended to overweight patients with OSA, as it has been shown thatweight reduction has additional health benefits. Treatment of underlying medicalconditions such as hypothyroidism or acromegaly has profound effect onapnea/hypopnea index. A subset of patients with OSA may benefit from supplementaloxygen and positional therapy. Presently, there are no effective pharmacotherapeuticagents for treatment of patients with OSA and the role of surgical treatment in OSA iscontroversial. However, pharmacological treatment of persisting residual sleepiness,despite adequate positive airway pressure therapy delivery and adherence, is indicatedand may improve daytime sleepiness.Key words : CPAP, Oral appliances, Modafinil, CPAP complianceUvulopalatopharyngoplasty, positional therapy

    Full Text Available Abstract Objective Biomarkers of adipose tissue may affect glucose and lipid metabolism and present pro-inflammatory properties, thus could be involved in the pathobiochemistry of cardiovascular disease (CVD. The coexistence of sleep apnea syndrome (OSA and metabolic risk factors of CVD is worth explaining. The aim of the study was to compare the serum adipocytokines in subjects with and without OSA, who had all elevated body mass index (BMI. Methods Overweight (BMI: 25.0-29.9 kg/m2 and obese (BMI: 30.0-39.9 kg/m2 OSA-suspected Caucasian males, aged 30-63, with no acute disease or chronic disorder underwent polysomnographic evaluation to select OSA-positive (AHI ≥ 5 and OSA-negative (AHI Results A decreased resistin level was observed in Over-OSA-Pos vs. Over-OSA-Neg subjects (P = 0.037 as well as in Obese-OSA-Pos vs. Obese-OSA-Neg (P = 0.045. No differences in leptin concentrations were observed. A positive correlation between leptin and BMI was in both overweight subgroups and a negative one between resistin and fasting glucose was in both obese subgroups. Conclusions OSA may decrease the serum resistin level in subjects with excess body mass and also may contribute to glucose metabolism, but has no influence on the leptin level.

    Full Text Available Se estima que al menos un tercio de los pacientes con enfermedad pulmonar obstructiva crónica moderada y severa tienen una alteración significativa en su composición corporal, lo cual se asocia con efectos clínicos deletéreos y con una mayor mortalidad. Sin embargo, hay evidencia insuficiente para respaldar que los pacientes que participan en un programa de rehabilitación respiratoria se beneficien en forma significativa de las intervenciones nutricionales dietarias, farmacológicas o la asociación de ambas, aunque aparentemente los últimos estudios publicados parecen sugerirlo. La recomendación actual es establecer desde que el paciente ingresa a un programa de rehabilitación respiratoria tanto el diagnóstico nutricional mediante la determinación del índice de masa corporal como el riesgo nutricional que corresponde a una baja involuntaria significativa de peso en determinado intervalo de tiempo, entregando al paciente un plan de alimentación y educación individualizado que debiera tener una duración mínima de 12 semanas.It is estimated that at least one third of patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD have a significant alteration of their body composition, which is associated with deleterious clinical effects and higher mortality. However, there is a lack of evidence to support that dietary, pharmacological or both nutritional interventions have significant clinical benefits in COPD patients who are participating in a pulmonary rehabilitation program. At the present time the recommendation is to establish a nutritional diagnosis of the COPD patients from the beginning of the pulmonary rehabilitation program using the measurement of body mass index (BMI and the estimation of the nutritional risk, which means a significant weight loss during a given period of time, followed by an individualized dietary and educational supplementation guide during at least 12 weeks.

    The case of a 40-year-old male patient with obstructive sleep apnea syndrome (OSAS) is reported, with emphasis on treatment with a dental appliance. This therapeutic approach, which has been focused on recent research, has as its objective, the posturing of the mandibule and, consequently, the tongue more anteriorly, thus in turn leading to an increase in the posterior oropharyngeal airway space (PAS). Cephalometry contributed determining in this case whereby enlargement limits were observed in the PAS with mandibular displacement. Clinical and polysomnographic controls showed subjective reduction of the excessive daytime sleepiness and objective decrease in apneas intensity to normal limits. Eight months follow-up evidenced the steady improvement.

    Sleep apnea is the most common sleep disturbance and it is an important risk factor for cardiovascular disorders. Its detection relies on a polysomnography, a combination of diverse exams. In order to detect changes due to sleep disturbances such as sleep apnea occurrences, without the need of combined recordings, we mainly analyze systolic blood pressure signals (maximal blood pressure value of each beat to beat interval). Nonstationarities in the data are uncovered by a segmentation procedure, which provides local quantities that are correlated to apnea-hypopnea events. Those quantities are the average length and average variance of stationary patches. By comparing them to an apnea score previously obtained by polysomnographic exams, we propose an apnea quantifier based on blood pressure signal. This furnishes an alternative procedure for the detection of apnea based on a single time series, with an accuracy of 82%.

  16. A new algorithm for detecting central apnea in neonates

    International Nuclear Information System (INIS)

    Apnea of prematurity is an important and common clinical problem, and is often the rate-limiting process in NICU discharge. Accurate detection of episodes of clinically important neonatal apnea using existing chest impedance (CI) monitoring is a clinical imperative. The technique relies on changes in impedance as the lungs fill with air, a high impedance substance. A potential confounder, however, is blood coursing through the heart. Thus, the cardiac signal during apnea might be mistaken for breathing. We report here a new filter to remove the cardiac signal from the CI that employs a novel resampling technique optimally suited to remove the heart rate signal, allowing improved apnea detection. We also develop an apnea detection method that employs the CI after cardiac filtering. The method has been applied to a large database of physiological signals, and we prove that, compared to the presently used monitors, the new method gives substantial improvement in apnea detection.

    Obstructive sleep apnea is a common disorder whose prevalence is linked to an epidemic of obesity in Western society. Sleep apnea is due to recurrent episodes of upper airway obstruction during sleep that are caused by elevations in upper airway collapsibility during sleep. Collapsibility can be increased by underlying anatomic alterations and/or disturbances in upper airway neuromuscular control, both of which play key roles in the pathogenesis of obstructive sleep apnea. Obesity and particu...

    Full Text Available We describe the case of a 12-year-old boy who developed temporal lobe epilepsy (TLE with daily complex partial seizures (CPS and monthly generalized seizures. Moreover, he frequently snored while asleep since early childhood. Polysomnography (PSG revealed severe obstructive sleep apnea with apnea–hypopnea index (AHI of 37.8/h. Video-PSG with simultaneous electroencephalography (EEG recording captured two ictal apneic episodes during sleep, without any motor manifestations. The onset of rhythmic theta activity in the midtemporal area on EEG was preceded by the onset of apnea by several seconds and disappeared soon after cessation of central apnea. One episode was accompanied by ictal bradycardia of <48 beats/min which persisted for 50 s beyond the end of epileptic activity. After treatment with carbamazepine and tonsillectomy/adenoidectomy, the seizures were well controlled and AHI decreased to 2.5/h. Paroxysmal discharges also disappeared during this time. Uncontrolled TLE complicated by sleep apnea should be evaluated for the presence of ictal central apnea/bradycardia.

    Full Text Available INTRODUCTION: Obstructive sleep apnea syndrome has a high prevalence among adults. Cephalometric variables can be a valuable method for evaluating patients with this syndrome. OBJECTIVE: To correlate cephalometric data with the apnea-hypopnea sleep index. METHODS: We performed a retrospective and cross-sectional study that analyzed the cephalometric data of patients followed in the Sleep Disorders Outpatient Clinic of the Discipline of Otorhinolaryngology of a university hospital, from June 2007 to May 2012. RESULTS: Ninety-six patients were included, 45 men, and 51 women, with a mean age of 50.3 years. A total of 11 patients had snoring, 20 had mild apnea, 26 had moderate apnea, and 39 had severe apnea. The distance from the hyoid bone to the mandibular plane was the only variable that showed a statistically significant correlation with the apnea-hypopnea index. CONCLUSION: Cephalometric variables are useful tools for the understanding of obstructive sleep apnea syndrome. The distance from the hyoid bone to the mandibular plane showed a statistically significant correlation with the apnea-hypopnea index.

    After irradiation of the neck for a squamous cell carcinoma of the tonsillar pillar and vocal cord, a 71-year-old man presented with a rapidly progressive sleep apnea syndrome. Previous reports describe the condition of patients with obstructive sleep apnea that developed after neck irradiation and secondary to supraglottic edema. Our patient had an obstructive component to his apnea similar to that described in previous cases, but, in addition, he had hypothyroidism. Myxedema is a well-described cause of both obstructive and central apnea. We believe both contributed to his condition. He was successfully treated by placement of a tracheostomy and by thyroid supplementation. In patients who present with sleep apnea after neck irradiation, especially with acute or severe symptoms, the differential diagnosis should include both a central cause from hypothyroidism as well as a peripheral obstructive cause from laryngeal edema.

    @@ Obstructive sleep apnea hypopnea syndrome (OSAHS) is a rather frequent disorder affecting 2%-4% of the general population. Large cohort studies have confirmed that obstructive sleep apnea (OSA) is an independent risk factor for cardiovascular disease (CVD), including myocardial infarction, hypertension, stroke and so on. For example, Sleep Heart Health Study (SHHS) demonstrated that the prevalence of CVD (including myocardial infarction, angina, coronary revascularization, heart failure, stroke) was 1.42 times greater in patients with OSA (apnea/hypopnea index (AHI)>11 events/hour) than in those without OSA.1 However, the exact mechanisms linking sleep apnea to cardiovascular morbidity remain unclear. Two studies2,3 published in this issue of the Journal measured a series of subclinical inflammatory factors in patients with OSA, and added new evidence linking sleep apnea to cardiovascular morbidity.

Although at present byssinosis is a rare disease in Spain, we describe its characteristics because of its historical interest amongst occupational respiratory diseases and because it is still relevant in developing countries. Chronic bronchitis can also be related to exposure at work to dust and smoke, and is often referred to as "industrial bronchitis". Historically, the relation of CPOD to occupation has been subject to controversy, but nowadays this relationship is accepted; we describe the present evidence supporting this relationship. Finally, we describe eosinophilic bronchitis without asthma, an entity that was described for the first time in 1989 and that can sometimes have an occupational origin, sharing aetiological agents with occupational asthma.

    Obstructive sleep apnea is a common disorder that causes patients to temporarily stop or decrease their breathing repeatedly during sleep. This results in fragmented, nonrestful sleep that can lead to symptoms such as morning headache and daytime sleepiness. Obstructive sleep apnea affects persons of all ages, with an increasing prevalence in those older than 60 years. The exact prevalence is unknown but is estimated to be between 2% and 14%. There are many health conditions associated with obstructive sleep apnea, including hypertension, coronary artery disease, cardiac arrhythmias, and depression. Loud snoring, gasping during sleep, obesity, and enlarged neck circumference are predictive clinical features. Screening questionnaires can be used to assess for sleep apnea, although their accuracy is limited. The diagnostic standard for obstructive sleep apnea is nocturnal polysomnography in a sleep laboratory. Home sleep apnea tests can be performed for certain patients but are generally considered less accurate. Continuous positive airway pressure is the first-line treatment; adherence rates are variable and seem to improve with early patient education and support. Other treatment modalities include weight reduction, oral appliance therapy, and surgery to correct anatomic obstructions, although there is insufficient evidence to support these types of surgeries. Bariatric surgery can improve sleep parameters and symptoms in obese patients with obstructive sleep apnea and can result in remission in many patients. PMID:27583421

    Study objectives To evaluate sex differences in predictors of obstructive sleep apnea (OSA) as per outcomes from home sleep apnea testing. Design This was a retrospective analysis of a large repository of anonymous test results and pretest risk factors for OSA. Setting and patients A total of 272,705 patients were referred for home sleep apnea testing from a variety of clinical practices for suspected sleep disordered breathing across North America from 2009 to 2013. Interventions Not applicable. Measurements and results Predictors of OSA (apnea hypopnea index4%≥5) were evaluated by multiple logistic regression; sex differences were evaluated by interaction effects. Middle age was the single most robust predictor of OSA for both sexes and was particularly foretelling for females (P<0.001) even after controlling for measures of adiposity and medical conditions. Females over the age of 45 years were much more likely to have OSA compared to their younger counterparts (78.7% vs 42.5%, respectively; odds ratio: 5.0) versus males (88.1% vs 68.8%, respectively; odds ratio: 3.4). Snoring, although more frequently reported by males, was similarly predictive of OSA for both sexes. Witnessed apneas and measures of adiposity were better predictors of OSA for males than females. Insomnia, depression, and use of sleep medication, although more commonly reported in females, did not predict OSA. Hypertension, although equally reported by both sexes, performed better as a predictor in females (P<0.001), even after controlling for age, measures of adiposity, and other medical conditions. Diabetes, heart disease, stroke, and sleepiness did not contribute unique variance in OSA in adjusted models. Conclusion This study found that males and females report different symptoms upon clinical evaluation for suspected sleep apnea, with some of the “classic” OSA features to be more common in and robustly predictive for males. The finding that advancing age uniquely and robustly

    Classic laryngomalacia presents in the awake infant with progressive stridor when agitated. Occult laryngomalacia usually presents with stridor in children older than 2 years and is limited to sleep or exercise. There have been no documented cases of occult laryngomalacia causing obstructive sleep apnea in infants. We report the youngest documented case of an infant with state-dependent laryngomalacia resulting in severe obstructive sleep apnea. This patient was successfully treated with supraglottoplasty, with resolution of symptoms. In conclusion, state-dependent laryngomalacia resulting in obstructive sleep apnea may present in children younger than 12 months of age. In these individuals, supraglottoplasty should be considered.

    Full Text Available Enhanced target organ damage and cardiovascular morbidity represent common issues observed in both resistant hypertension and obstructive sleep apnea. Common pathophysiological features and risk factors justify their coexistence, especially in individuals with increased upper-body adiposity. Impaired sodium handling, sympathetic activation, accelerated arterial stiffening, and impaired cardiorenal hemodynamics contribute to drug-resistant hypertension development in obstructive sleep apnea. Effective CPAP therapy qualifies as an effective “add-on” to the underlying antihypertensive pharmacological therapy, and emerging evidence underlines the favorable effect of mineralocorticoid antagonists on both resistant hypertension and obstructive sleep apnea treatment.

  2. Central Sleep Apnea at High Altitude.

    Burgess, Keith R; Ainslie, Philip N

    2016-01-01

    The discovery of central sleep apnea (CSA) at high altitude is usually attributed to Angelo Mosso who published in 1898. It can occur in susceptible individuals at altitude above 2000 m, but at very high altitude, say above 5000 m, it will occur in most subjects. Severity is correlated with ventilatory responsiveness, particularly to hypoxia. Theoretically, it should spontaneously improve with time and acclimatization. Although the time course of resolution is not well described, it appears to persist for more than a month at 5000 m.It occurs due to the interaction of hypocapnia with stages 1 and 2 NREM sleep, in the presence of increased loop-gain. The hypocapnia is secondary to hypoxic ventilatory drive. With acclimatization, one might expect that the increase in PaO2 and cerebral blood flow (CBF) would mitigate the CSA. However, over time, both the hypoxic and hypercapnic ventilatory responses increase, causing an increase in loop gain which is a counteracting force.The severity of the CSA can be reduced by descent, supplemental oxygen therapy, oral or intravenous acetazolamide. Recent studies suggest that acute further increases in cerebral blood flow will substantially, but temporarily, reduce central sleep apnea, without altering acid based balance. Very recently, bi-level noninvasive ventilation has also been shown to help (mechanism unknown). Sleep quality can be improved independent of the presence of CSA by the use of benzodiazepine sedation. PMID:27343103

    2015-12-01

    Full Text Available Obstructive sleep apnea (OSA is a disease of multicasual etiology. The risk factors include obesity, among other issues. Hence, it is extremely important to determine the effect of body weight on the severity of OSA. The aim of the study was to evaluate the influence of the body weight expressed as body mass index (BMI, on the value of upper airways diameter and on the AHI (Apnea-Hypopnea Index value. The study was comprised of 41 patients diagnosed with OSA by way of polysomnography. Each patient was first examine via a lateral cephalometric image of the skull, which served to measure the upper and lower diameter of the upper airways. BMI was also calculated for each patient. Statistical analysis was carried out in accordance with Pearson’s correlation coefficient test. Our work demonstrated a negative correlation between BMI and the diameter of the upper airways, and a positive correlation between BMI and AHI value. We thus put forward that the increase in body weight in patients with OSA can contribute to the severity of the disease, regardless of the fact that it may not lead to a reduction of the lumen of the upper airways.

    Objective: This study aimed at assessing the relationship between facial morphological patterns (I, II, III, Long Face and Short Face) as well as facial types (brachyfacial, mesofacial and dolichofacial) and obstructive sleep apnea (OSA) in patients attending a center specialized in sleep disorders. Methods: Frontal, lateral and smile photographs of 252 patients (157 men and 95 women), randomly selected from a polysomnography clinic, with mean age of 40.62 years, were evaluated. In order to obtain diagnosis of facial morphology, the sample was sent to three professors of Orthodontics trained to classify patients' face according to five patterns, as follows: 1) Pattern I; 2) Pattern II; 3) Pattern III; 4) Long facial pattern; 5) Short facial pattern. Intraexaminer agreement was assessed by means of Kappa index. The professors ranked patients' facial type based on a facial index that considers the proportion between facial width and height. Results: The multiple linear regression model evinced that, when compared to Pattern I, Pattern II had the apnea and hypopnea index (AHI) worsened in 6.98 episodes. However, when Pattern II was compared to Pattern III patients, the index for the latter was 11.45 episodes lower. As for the facial type, brachyfacial patients had a mean AHI of 22.34, while dolichofacial patients had a significantly statistical lower index of 10.52. Conclusion: Patients' facial morphology influences OSA. Pattern II and brachyfacial patients had greater AHI, while Pattern III patients showed a lower index. PMID:26691971

    Full Text Available The global epidemic of childhood and adolescent obesity and its immediate as well as long-term consequences for obese individuals and society as a whole cannot be overemphasized. Obesity in childhood and adolescence is associated with an increased risk of adult obesity and clinically significant consequences affecting the cardiovascular and metabolic systems. Importantly, obesity is additionally complicated by obstructive sleep apnea (OSA, occurring in up to 60% of obese children. OSA, which is diagnosed using the gold standard polysomnogram (PSG, is characterised by snoring, recurrent partial (hypopneas or complete (apneas obstruction of the upper airway. OSA is frequently associated with intermittent oxyhemoglobin desaturations, sleep disruption, and sleep fragmentation. There is emerging data that OSA is associated with cardiovascular burden including systemic hypertension, changes in ventricular structure and function, arterial stiffness, and metabolic syndromes. Thus, OSA in the context of obesity may independently or synergistically magnify the underlying cardiovascular and metabolic burden. This is of importance as early recognition and treatment of OSA in obese children are likely to result in the reduction of cardiometabolic burden in obese children. This paper summarizes the current state of understanding of obesity-related OSA. Specifically, this paper will discuss epidemiology, pathophysiology, cardiometabolic burden, and management of obese children and adolescents with OSA.

    Study Objectives: To test the hypothesis that head position, separately from trunk position, is an additionally important factor for the occurrence of apnea in obstructive sleep apnea (OSA) patients. Design: Prospective cohort study. Setting: St. Lucas Andreas Hospital, Amsterdam, the Netherlands. Patients and Participants: Three hundred patients referred to our department because of clinically suspected OSA. Interventions: N/A Measurements and Results: Patients underwent overnight polysomnography with 2 position sensors: one on the trunk, and one in the mid-forehead. Of the 300 subjects, 241 were diagnosed with OSA, based on an AHI > 5. Of these patients, 199 could be analyzed for position-dependent OSA based on head and trunk position sensors (AHI in supine position twice as high as AHI in non-supine positions): 41.2% of the cases were not position dependent, 52.3% were supine position dependent based on the trunk sensor, 6.5% were supine position dependent based on the head sensor alone. In 46.2% of the trunk supine position-dependent group, head position was of considerable influence on the AHI (AHI was > 5 higher when the head was also in supine position compared to when the head was turned to the side). Conclusions: The results of this study confirm our hypothesis that the occurrence of OSA may also be dependent on the position of the head. Therefore in patients with a suspicion of position-dependent OSA, sleep recording with dual position sensors placed on both trunk and head should be considered.

    Full Text Available PURPOSE: The aim of this study was to evaluate markers of systemic oxidative stress and antioxidant capacity in subjects with and without OSAS in order to investigate the most important factors that determine the oxidant-antioxidant status. METHODS: A total of 66 subjects referred to our Sleep laboratory were examined by full polysomnography. Oxidative stress and antioxidant activity were assessed by measurement of the derivatives of reactive oxygen metabolites (d-ROMs and the biological antioxidant capacity (BAP in blood samples taken in the morning after the sleep study. Known risk factors for oxidative stress, such as age, sex, obesity, smoking, hypelipidemia, and hypertension, were investigated as possible confounding factors. RESULTS: 42 patients with OSAS (Apnea-Hypopnea index >15 events/hour were compared with 24 controls (AHI<5. The levels of d-ROMS were significantly higher (p = 0.005 in the control group but the levels of antioxidant capacity were significantly lower (p = 0.004 in OSAS patients. The most important factors predicting the variance of oxidative stress were obesity, smoking habit, and sex. Parameters of sleep apnea severity were not associated with oxidative stress. Minimal oxygen desaturation and smoking habit were the most important predicting factors of BAP levels. CONCLUSION: Obesity, smoking, and sex are the most important determinants of oxidative stress in OSAS subjects. Sleep apnea might enhance oxidative stress by the reduction of antioxidant capacity of blood due to nocturnal hypoxia.

    Full Text Available Background. Prior research indicates that heart failure (HF patients exhibit significant cognitive deficits on neuropsychological testing. Sleep apnea is associated with both HF and reduced cognitive function, but the combined impact of these conditions on cognitive function is unknown. Methods. In the current study, 172 older adults with a dual diagnosis of HF and sleep apnea or HF alone completed a battery of cognitive tests measuring attention, executive functioning, and memory. Results. Relative to patients with HF alone, persons with both HF and sleep apnea performed worse on measures of attention after adjusting for demographic and medical variables. Conclusions. The current findings suggest that HF patients with comorbid sleep apnea may be at greater risk for cognitive impairment relative to HF patient without such history. Further work is needed to clarify mechanisms for these findings and to determine whether the interactive effects on cognitive function lead to poorer patient outcomes.

    Sleep apnea is a rare but a well-known clinical feature of type I Chiari malformation. It may be obstructive or central in nature. Sleep apnea in patients with type I Chiari malformation rarely presents without accompanying neurological signs or symptoms. We here report a case of a 10-year-old girl who presented with central sleep apnea without any other neurological signs but was ultimately diagnosed with type I Chiari malformation. The patient initially showed mild improvement in symptoms after administration of an acetazolamide. Finally, posterior fossa decompression dramatically improved her respiratory status during sleep, both clinically and on polysomnography. This case suggests that type I Chiari malformation should be considered in the differential diagnoses of central apneas in children, even if there are no other neurological signs and symptoms. Furthermore, sagittal craniocervical magnetic resonance imaging may be necessary for a definitive diagnosis.

  10. CT demonstration of pharyngeal narrowing in adult obstructive sleep apnea

    International Nuclear Information System (INIS)

    Sleep apnea is a major cause of daytime hypersomnolence. Among the proposed etiologies, focal obstruction of the airways at the level of the pharynx has been suggested but not proven. Using computed tomography, the cross-sectional area of the airway can be readily assessed. Thirty-three adults with clinically proven sleep apnea and 12 normal adults underwent systematic computed tomography of the neck. Significant airway narrowing was demonstrated in all the patients with obstructive sleep apnea, whereas no such narrowing was seen in the controls. In 11, the narrowing was at a single level, whereas in 22 patients two or more levels were affected. This study has shown that a structurally abnormal airway may serve as an anatomic substrate for the development of sleep apnea. On the basis of this evidence, uvulopalatopharyngoplasty has been performed in two patients with relief of symptoms in one

The aim of this study was to assess the relationship between SRBD and depressive symptoms in a population of school-aged children.Methods: The study population comprised 94 children affected by SRBD and 107 healthy children. To identify the severity of SRBD, an overnight respiratory evaluation was performed. All subjects filled out the Italian version of the Children Depression Inventory (CDI to screen for the presence of depressive symptoms.Results: The group with SRBD showed higher CDI scores than the group without SRBD, with a positive correlation found between CDI scores, apnea-hypopnea index, and oxygen desaturation index values. Logistic regression showed that an apnea-hypopnea index ≥ 3 and an oxygen desaturation index ≥ 1 could be risk factors for development of depressive symptoms. According to receiver-operating characteristic curve analysis, the cutoff point for the apnea-hypopnea index that could cause a pathological CDI score (≥19 was >5.66, and the cutoff point for the oxygen desaturation index was >4.2. The limitations of this study are that our data are derived from one single psychometric test and not from a complete psychiatric evaluation, and our

    Full Text Available Background: The mechanisms associated with the cardiovascular consequences of obstructive sleep apnea include abrupt changes in autonomic tone, which can trigger cardiac arrhythmias. The authors hypothesized that nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea. Objective: To analyze the relationship between obstructive sleep apnea and abnormal heart rhythm during sleep in a population sample. Methods: Cross-sectional study with 1,101 volunteers, who form a representative sample of the city of São Paulo. The overnight polysomnography was performed using an EMBLA® S7000 digital system during the regular sleep schedule of the individual. The electrocardiogram channel was extracted, duplicated, and then analyzed using a Holter (Cardio Smart® system. Results: A total of 767 participants (461 men with a mean age of 42.00 ± 0.53 years, were included in the analysis. At least one type of nocturnal cardiac rhythm disturbance (atrial/ventricular arrhythmia or beat was observed in 62.7% of the sample. The occurrence of nocturnal cardiac arrhythmias was more frequent with increased disease severity. Rhythm disturbance was observed in 53.3% of the sample without breathing sleep disorders, whereas 92.3% of patients with severe obstructive sleep apnea showed cardiac arrhythmia. Isolated atrial and ventricular ectopy was more frequent in patients with moderate/severe obstructive sleep apnea when compared to controls (p < 0.001. After controlling for potential confounding factors, age, sex and apnea-hypopnea index were associated with nocturnal cardiac arrhythmia. Conclusion: Nocturnal cardiac arrhythmia occurs more frequently in patients with obstructive sleep apnea and the prevalence increases with disease severity. Age, sex, and the Apnea-hypopnea index were predictors of arrhythmia in this sample.

    Background The classification of obstructive sleep apnea is on the basis of sleep study criteria that may not adequately capture disease heterogeneity. Improved phenotyping may improve prognosis prediction and help select therapeutic strategies. Objectives: This study used cluster analysis to investigate the clinical clusters of obstructive sleep apnea. Methods An ascending hierarchical cluster analysis was performed on baseline symptoms, physical examination, risk factor exposure and co-morbidities from 18,263 participants in the OSFP (French national registry of sleep apnea). The probability for criteria to be associated with a given cluster was assessed using odds ratios, determined by univariate logistic regression. Results: Six clusters were identified, in which patients varied considerably in age, sex, symptoms, obesity, co-morbidities and environmental risk factors. The main significant differences between clusters were minimally symptomatic versus sleepy obstructive sleep apnea patients, lean versus obese, and among obese patients different combinations of co-morbidities and environmental risk factors. Conclusions Our cluster analysis identified six distinct clusters of obstructive sleep apnea. Our findings underscore the high degree of heterogeneity that exists within obstructive sleep apnea patients regarding clinical presentation, risk factors and consequences. This may help in both research and clinical practice for validating new prevention programs, in diagnosis and in decisions regarding therapeutic strategies. PMID:27314230

    A 52-year-old female with a history of poorly controlled resistant hypertension was admitted to our hospital with severe hypertension. She had a history of fatigue and intermittent episodes of palpitations. Laboratory evaluation was significant for elevated 24-h urinary catecholamine levels (3,5 times the upper normal levels). This case was presenting with a clinical and biochemical picture indistinguishable from that of pheochromocytoma. However, neither computed tomography nor meta-iodo-benzyl-guanidine scintigraphy detected any catecholamine-producing tumor in or outside the adrenal glands. Our patient was screened with full polysomnography because of heavy snoring, daytime somnolence and obesity. It revealed severe obstructive sleep apnea syndrome. After three months of continuous positive airway pressure therapy, the patient experienced resolution of his presenting symptoms, improved blood pressure control and normalization of his urinary catecholamine levels. This case highlights sleep disordered breathing as a potentially reversible cause of pseudo-pheochromocytoma. PMID:27217898

    The aim of the present study was to investigate the prevalence of obstructive sleep apnea syndrome (OSAS) among the Norwegian population with Treacher Collins syndrome (TCS). A secondary aim was to establish whether TCS phenotype severity is associated with OSAS severity. A prospective case study design was used. Individuals who were 5 years old and above with a known diagnosis of TCS in Norway were invited to participate in a study. The study included genetic testing, medical and dental examinations and polysomnography. All participants demonstrated disturbed respiration during sleep; 18/19 met the diagnostic criteria for OSAS. Subjectively evaluated snoring was not a reliable predictor of OSAS. We found no significant association between TCS phenotype severity and the severity of OSAS. OSAS is common in TCS, but there is no association with the phenotype severity. Individuals diagnosed with TCS must undergo sleep studies to identify the presence of OSAS.

    Sleep and respiration data from two French medical high altitude expeditions (Annapurna 4,800 m and Mt Sajama 6,542 m) are presented. Difficulties in maintaining sleep and a SWS decrease were found with periodic breathing (PB) during both non-REM and REM sleep. Extent of PB varied considerably among subjects and was not correlated to the number of arousals but to the intercurrent wakefulness duration. There was a positive correlation between the time spent in PB and the individual hypoxic ventilatory drive. The relation between PB, nocturnal desaturation, and mountain sickness intensity are discussed. Acclimatization decreased the latency toward PB and improved sleep. Hypnotic benzodiazepine intake (loprazolam 1 mg) did not worsen either SWS depression or apneas and allowed normal sleep reappearance after acclimatization.

    The sleep apnea syndrome (SAS), which is defined by more than 5 apneas or hypopneas per hour of sleep (9), is quite a frequent affection which concerns 1.4 to 10% of general population (1.7). The major daytime complaints of the SAS are daytime sleepiness, memory and attention disorders, headaches and asthenia especially in the morning, and sexual impotence (9). The nocturnal manifestations are dominated by sonorous and generally long standing snoring, increased by dorsal decubitus and intake of alcohol, with repeated interruptions by respiratory arrests. These manifestations are always noted but rarely spontaneously reported. The sleep, non refreshing, is agitated and perturbed by numerous awakenings. The findings of the clinical examination are poor: obesity is found in 2/3 of the cases and arterial hypertension in 1/2 of the cases (20). Polygraphic recording during sleep only permits an absolute diagnosis. This frequent affection is a real problem of public health because of its numerous complications (3, 10, 12, 13, 18, 21). Symptoms of depression are often found when a patient with a SAS is examined and conversely, symptoms which evoke a SAS can be found in the clinical examination of depressed patients. We decided so to study the thymic and anxious status of 24 patients investigated for a SAS and submitted to a polygraphic recording during sleep. Four clinical parameters were studied: DSM III-R diagnosis criteria, Montgomery and Asberg Depression Rating Scale (MADRS), Hamilton Anxiety Rating Scale (HARS) and thymasthenia rating scale of Lecrubier, Payan and Puech. We also reported Total Sleep Time (TST = 6.5 +/- 1.5), Apnea Hypopnea Index (AHI = 26.7 +/- 21.6), number (2.1 +/- 2.8/h) and duration (174.2 +/- 150.8 s/h) of hypoxic events. Results showed that among 24 patients, 8 were depressed according to DSM III-R diagnosis criteria and had MADRS > 25, 22 were anxious, 11 had a major anxiety (HARS > 15) and 15 presented thymasthenia (SET > 15).

This coexistence is known as overlap syndrome and is the result of chance rather than a pathophysiological link. Although there are claims of a very high incidence of OSAS in COPD patients, recent studies report that it is similar to the general population. Overlap patients present sleep-disordered breathing associated to upper and lower airway obstruction and a reduction in respiratory drive. These patients present unique characteristics, which set them apart from either COPD or OSAS patients. COPD and OSAS are independent risk factors for cardiovascular events and their coexistence in overlap syndrome probably increases this risk. The mechanisms underlying cardiovascular risk are still unclear, but may involve systemic inflammation, endothelial dysfunction, and tonic elevation of sympathetic neural activity. The treatment of choice for overlap syndrome in stable patients is CPAP with supplemental oxygen for correction of upper airway obstructive episodes and hypoxemia during sleep.Keywords: chronic obstructive pulmonary disease, obstructive sleep apnea syndrome, overlap syndrome, sleep, cardiovascular disease

    Chronic sleep disruption (CSD) is a cardinal feature of sleep apnea that predicts impaired wakefulness. Despite effective treatment of apneas and sleep disruption, patients with sleep apnea may have persistent somnolence. Lasting wake disturbances in treated sleep apnea raise the possibility that CSD may induce sufficient degeneration in wake-activated neurons (WAN) to cause irreversible wake impairments. Implementing a stereological approach in a murine model of CSD, we found reduced neurona...

    Small urinary protein loss (low-grade albuminuria or microalbuminuria) may reflect altered permeability of the glomerular filtration barrier. In the present study, it was hypothesized that children with obstructive sleep apnea have an increased risk of microalbuminuria compared with control subjects without sleep-disordered breathing. Albumin-to-creatinine ratio was measured in morning spot urine specimens collected from consecutive children with or without snoring who were referred for polysomnography. Three groups were studied: (i) control subjects (no snoring, apnea-hypopnea index  5 episodes∙h(-1) ; n = 27). Indications for polysomnography in control subjects included nightmares, somnambulism and morning headaches. An albumin-to-creatinine ratio > median value in the control group (1.85 mg of albumin per g of creatinine) was defined as elevated. Logistic regression analysis revealed that children with moderate-to-severe obstructive sleep apnea, but not those with mild obstructive sleep apnea, had increased risk of elevated albumin-to-creatinine ratio relative to controls (reference) after adjustment for age, gender and presence of obesity: odds ratio 3.8 (95% confidence interval 1.1-12.6); P = 0.04 and 1.5 (0.6-3.7); P > 0.05, respectively. Oxygen desaturation of hemoglobin and respiratory arousal indices were significant predictors of albumin-to-creatinine ratio (r = 0.31, P = 0.01; and r = 0.43, P < 0.01, respectively). In conclusion, children with moderate-to-severe obstructive sleep apnea are at significantly higher risk of increased low-grade excretion of albumin in the morning urine as compared with control subjects without obstructive sleep apnea. These findings may reflect altered permeability of the glomerular filtration barrier related to nocturnal hypoxemia and sympathetic activation which are induced by obstructive sleep apnea.

  5. Sleep apnea-hypopnea quantification by cardiovascular data analysis.

    Sabrina Camargo

    Full Text Available Sleep disorders are a major risk factor for cardiovascular diseases. Sleep apnea is the most common sleep disturbance and its detection relies on a polysomnography, i.e., a combination of several medical examinations performed during a monitored sleep night. In order to detect occurrences of sleep apnea without the need of combined recordings, we focus our efforts on extracting a quantifier related to the events of sleep apnea from a cardiovascular time series, namely systolic blood pressure (SBP. Physiologic time series are generally highly nonstationary and entrap the application of conventional tools that require a stationary condition. In our study, data nonstationarities are uncovered by a segmentation procedure which splits the signal into stationary patches, providing local quantities such as mean and variance of the SBP signal in each stationary patch, as well as its duration L. We analysed the data of 26 apneic diagnosed individuals, divided into hypertensive and normotensive groups, and compared the results with those of a control group. From the segmentation procedure, we identified that the average duration , as well as the average variance , are correlated to the apnea-hypoapnea index (AHI, previously obtained by polysomnographic exams. Moreover, our results unveil an oscillatory pattern in apneic subjects, whose amplitude S* is also correlated with AHI. All these quantities allow to separate apneic individuals, with an accuracy of at least 79%. Therefore, they provide alternative criteria to detect sleep apnea based on a single time series, the systolic blood pressure.

    This study aimed at determining cerebral hemodynamic parameters in human subjects during breath holding using near infrared spectroscopy (NIRS). Breath holding serves as a method of simulation OSA (Obstructive Sleep Apnea). Data was acquired non-invasively from 40 subjects, twenty OSA sufferers (10 females, 10 males, age 20-70 years), and twenty normal volunteers (10 females, 10 males, age 20-65 years). Measurements were conducted using a LED Imager (LEDI) during breath holding. In comparing OSA subjects with controls during breath holding, a consistent increase or even a decrease in oxy- ([O IIHb]), deoxy- ([HHb]), total hemoglobin ([tHb]) concentrations, and tissue hemoglobin oxygen saturation (SO II) in the regional brain tissue were observed. The LEDI probe consists of 4 sources and 10 detectors serving as 4 sets of 1 source and 4 detectors each. A three wavelength (730, 805, and 850 nm) LED was used and the wavelengths were switched sequentially. The distance between sources and the source-detector separation were 2.5 cm. Data acquisition consisted of three segments, baseline for one minute, followed by a period of breath holding, and then 2 minutes of recovery time. The duration of the breath holding was subject-dependent. Our investigation proves that NIR spectroscopy could be used as a tool for detecting cerebral hemodynamics and also serves as a method of screening patients with OSA.

    Sleep plays the important role of rejuvenating the body, especially the central nervous system. However, more than thirty million people suffer from sleep disorders and sleep deprivation. That can cause serious health consequences by increasing the risk of hypertension, diabetes, heart attack and so on. Apart from the physical health risk, sleep disorders can lead to social problems when sleep disorders are not diagnosed and treated. Currently, sleep disorders are diagnosed through sleep study in a sleep laboratory overnight. This involves large expenses in addition to the inconvenience of overnight hospitalization and disruption of daily life activities. Although some systems provide home based diagnosis, most of systems record the sleep data in a memory card, the patient has to face the inconvenience of sending the memory card to a doctor for diagnosis. To solve the problem, we propose a wireless sensor system for sleep apnea, which enables remote monitoring while the patient is at home. The system has 5 channels to measure ECG, Nasal airflow, body position, abdominal/chest efforts and oxygen saturation. A wireless transmitter unit transmits signals with Zigbee and a receiver unit which has two RF modules, Zigbee and Wi-Fi, receives signals from the transmitter unit and retransmits signals to the remote monitoring system with Zigbee and Wi-Fi, respectively. By using both Zigbee and Wi-Fi, the wireless sensor system can achieve a low power consumption and wide range coverage. The system's features are presented, as well as continuous monitoring results of vital signals.

    The human interface software for the Lockheed Martin Specialty Components (LMSC) Active/Passive Neutron Examination & Analysis System (APENA) provides a user friendly operating environment for the movement and analysis of waste drums. It is written in Microsoft Visual C++ on a Windows NT platform. Object oriented and multitasking techniques are used extensively to maximize the capability of the system. A waste drum is placed on a loading platform with a fork lift and then automatically moved into the APNEA chamber in preparation for analysis. A series of measurements is performed, controlled by menu commands to hardware components attached as peripheral devices, in order to create data files for analysis. The analysis routines use the files to identify the pertinent radioactive characteristics of the drum, including the type, location, and quantity of fissionable material. At the completion of the measurement process, the drum is automatically unloaded and the data are archived in preparation for storage as part of the drum`s data signature. 3 figs.

  9. Papilledema in obstructive sleep apnea syndrome

    International Nuclear Information System (INIS)

    We report a diagnostically challenging case of papilloedema in a morbidly obese, 25 year old male who presented to us with blurring of vision of both eyes, but more marked in the right. Fundus examination revealed severe papilloedema, with corresponding visual field and colour vision defects. He was worked up for possible life threatening causes of papilloedema like intracranial space occupying lesion but his CT scan was normal. As his hematocrit was in the polycythemic range, multiple venesections were performed in fear that the hyperviscosity picture could be a contributing factor. However there was no change in symptoms or the fundus appearance. We could not come to a diagnosis of idiopathic intracranial hypertension too because he refused lumbar puncture. A sleep study was done as he did give symptoms of mild obstructive sleep apnea but the results were that of severe disease. He was given therapeutic nocturnal oxygen by CPAP to prevent further cardiovascular and respiratory complications and interestingly enough it helped in treating the papilloedema. He was seen 2 months after commencement of continuous positive airway pressure (CPAP) with good functional and anatomical recovery. (author)

  10. Resistant Hypertension and Obstructive Sleep Apnea

    Full Text Available Hypertension (HTN is a modifiable, highly prevalent risk factor for cardiovascular morbidity and renal dysfunction worldwide. In the United States, HTN affects one in three adults, contributes to one out of every seven deaths and to nearly half of all cardiovascular disease-related deaths. HTN is considered resistant when the blood pressure remains above goal despite lifestyle modification and administration of three antihypertensive agents of different classes including a diuretic. Large population-based studies have suggested that obstructive sleep apnea (OSA is a risk factor for resistant HTN. The mechanism proposed is a pattern of intermittent hypoxia associated with hyperaldosteronism, increased sympathetic tone, endothelial dysfunction, and inflammation. In this review we discuss the association between OSA and resistant HTN, the physiologic mechanisms linking OSA with resistant HTN, and the effect of continuous positive airway pressure therapy (CPAP on blood pressure in patients with resistant HTN. While the reduction in blood pressure with CPAP is usually modest in patients with OSA, a decrease of only a few mmHg in blood pressure can significantly reduce cardiovascular risk. Patients presenting to a center specializing in management of hypertension should be screened and treated for OSA as a potentially modifiable risk factor.

    Our study included 42 patients with obstructive sleep apnea (OSAS) confirmed by polysomnography. In these patients we investigated the clinical manifestations, the results of the laboratory examinations, including polysomnography, ORL observations and tests of pulmonary function, as well as the therapeutic results. Our patients presented a serious set of symptoms which included excessive daytime sleepiness, snoring, obesity, craniofacial abnormalities, systemic hypertension, cardiac arrhythmias, incapacity to work with precocious retirement, marital conflicts and high incidence of accidents, namely traffic accidents. An adequate treatment, mostly with nasal CPAP (continuous positive airway pressure), induced marked relief of the symptoms; some patients had an advantage in surgical treatment and weight reduction. OSAS is a frequent entity, affecting mostly male adults after the 5th decade. The lack of knowledge about this entity and the common social acceptance of some of its cardinal symptoms induces considerable delays in its diagnosis. The severity of the symptoms, the personal and social risks of excessive daytime sleepiness, the cardiocirculatory effects and the risk of sudden death during sleep justify an early diagnosis in order to prevent the severe evolution of the disease. Its complex physiopathology and multiple etiological factors justify a multidisciplinary approach. PMID:7653280

  12. Genioglossus fatigue in obstructive sleep apnea.

    2012-08-15

    Obstructive sleep apnea (OSA) is a prevalent disorder that may cause cardiovascular disease and fatal traffic accidents but the pathophysiology remains incompletely understood. Increased fatigability of the genioglossus (the principal upper airway dilator muscle) might be important in OSA pathophysiology but the existing literature is uncertain. We hypothesized that the genioglossus in OSA subjects would fatigue more than in controls. In 9 OSA subjects and 9 controls during wakefulness we measured maximum voluntary tongue protrusion force (Tpmax). Using surface electromyography arrays we measured the rate of decline in muscle fiber conduction velocity (MFCV) during an isometric fatiguing contraction at 30% Tpmax. The rate of decline in MFCV provides an objective means of quantifying localized muscle fatigue. Linear regression analysis of individual subject data demonstrated a significantly greater decrease in MFCV in OSA subjects compared to control subjects (29.2 ± 20.8% [mean ± SD] versus 11.2 ± 20.8%; p=0.04). These data support increased fatigability of the genioglossus muscle in OSA subjects which may be important in the pathophysiology of OSA.

    Obstructive sleep apnea (OSA) is a prevalent sleep disorder which is characterized by recurrent upper closure with oxygen desaturation and sleep disruption. OSA increases the risk of vascular disorders in the form of stroke, myocardial infarction, congestive heart failure, and hypertension. The mechanisms underlying the vascular disorders are several and include intermittent hypoxia with release of cytokines, angiogenic inhibitors, free radicals, and adhesion molecules. During apneas, arterial blood pressure gradually rises and surges abruptly after the termination of apnea. Two thirds of patients with OSA will ultimately have diurnal hypertension. This review discusses the literature supporting the significant role of OSA in hypertension and the effect of OSA treatment on blood pressure. PMID:25139780

    Experience with the original Montgomery silicone tracheal cannulas in 47 patients with obstructive sleep apnea has been reported. Further experience with 10 obstructive sleep apnea patients who used modified silicone tracheal cannulas that permit periodic self-removal, cleaning, and reinsertion was analyzed. Two patients used the tube briefly and without complications. The remaining eight patients used the modified cannula for 18 to 24 months. The average number of office visits following insertion was three. Compared to the original cannulas, there were markedly fewer difficulties with granulations, infection, and tube malposition with the modified cannulas. The improvements make this modified device a useful tool worth further study in obstructive sleep apnea patients requiring tracheostomy. PMID:2299956

  15. CT findings in adults with obstructive sleep apnea

    International Nuclear Information System (INIS)

    The obstructive sleep apnea syndrome (OSAS) is characterized by recurrent obstruction of the upper airway during sleep. In this study, we performed CT scans in 20 adult OSAS patients and 6 control subjects, and measured the airspaces in the nasopharynx, mesopharynx and hypopharynx, using an image analyzer. The airspaces were significantly smaller at all sites of the pharynx in OSAS patients than in the control subjects, but they did not show a positive correlation with the apnea index or the body mass index. In good responders whose apnea indexes improved more than 50% after uvulo-palato-pharyngoplasty (UPPP), the nasopharyngeal and mesopharyngeal airspaces were significantly smaller, and the hypopharyngeal space tended to be larger than in poor responders. Our results suggest that CT scan is a helpful method for analyzing the area of the upper airway, especially in relation to the response to UPPP in adults with OSAS. (author)

    Spontaneously hypertensive rats (SHR), like patients with sleep apnea, have hypertension, increased sympathetic activity, and increased chemoreceptor drive. We investigated the role of carotid chemoreceptors in cardiovascular responses induced by obstructive apnea in awake SHR. A tracheal balloon and vascular cannulas were implanted, and a week later, apneas of 15 s each were induced. The effects of apnea were more pronounced in SHR than in control rats (Wistar Kyoto; WKY). Blood pressure increased by 57±3 mmHg during apnea in SHR and by 28±3 mmHg in WKY (pchemoreceptors were then inactivated by the ligation of the carotid body artery, and apneas were induced two days later. The inactivation of chemoreceptors reduced the responses to apnea and abolished the difference between SHR and controls. The apnea-induced hypertension was 11±4 mmHg in SHR and 8±4 mmHg in WKY. The respiratory effort was 15±2 mmHg in SHR and 15±2 mmHg in WKY. The heart rate fell 63±18 bpm in SHR and 52±14 bpm in WKY. Similarly, when the chemoreceptors were unloaded by the administration of 100% oxygen, the responses to apnea were reduced. In conclusion, arterial chemoreceptors contribute to the responses induced by apnea in both strains, but they are more important in SHR and account for the exaggerated responses of this strain to apnea.

    Full Text Available Objectives: The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective. Material and Methods: A total of 68 patients with obstructive sleep apnea syndrome (OSAS including, 31 with mild, 23 with moderate and 14 with severe OSAS were treated with a mandibular advancement device (MAD and monitored with polysomnography. Results: 25 of the 31 mild, 15 of the 23 moderate and 2 of the 14 severe OSAS patients were cured of their OSAS if a post treatment apnea-hypopnea index of less than 5 is regarded as cured. The odds ratios for success with MAD therapy are 3 for women over men, 14.9 for mild obstructive sleep apnea, 5.42 for moderate obstructive sleep apnea if severe obstructive sleep apnea is assigned an odds ratio of 1. Conclusions: The use of the apnea-hypopnea index alone is useful in mild and moderate disease to predict the effectiveness of mandibular advancement device. Treatment with a mandibular advancement device is very effective in treating mild and moderate obstructive sleep apnea. Conservative treatment with a mandibular advancement device can be successful in less severe grades of sleep apnea and may be an alternative for non-surgical patients with severe obstructive sleep apnea intolerant of Continuous Positive Airway Pressure management.

    Full Text Available Objective: the alteration of hormones regulating sodium and water status is related to renal failure in obstructive jaundice (OJ. Experimental design: OJ was induced by common bile duct ligation. Samples were obtained from the control (SO and OJ groups at 24 and 72 hours, and at 7 days. Different parameters related to biliary obstruction, liver and renal injury, and vasoactive mediators such as renin, aldosterone, endothelin-1 (ET-1 and prostaglandin E2 (PGE2 were studied. Results: bile duct ligation caused an increase in total bilirubin (p < 0.001 and alkaline phosphatase (AP (p < 0.001. The SO and OJ groups had the same values for diuresis, renin, and creatinine clearance at 24 h. However, animals with OJ had a lower sodium concentration in urine than SO animals (p < 0.01, as well as an increase in aldosterone levels (p < 0.03. ANP levels were moderately increased during OJ but did not reach statistical significance when compared to the SO group. In contrast, OJ animals showed a rise in serum ET-1 concentration (p < 0.001 and increased PGE2 in urine (p < 0.001. Conclusions: biliary obstruction induced an increase in ET-1 release and PGE2 urine excretion. These hormones might play a role during the renal complications associated with renal disturbances that occur during OJ.

    Full Text Available Abstract For over two decades clinical studies have been conducted which suggest the existence of a relationship between depression and Obstructive Sleep Apnea (OSA. Recently, Ohayon underscored the evidence for a link between these two disorders in the general population, showing that 800 out of 100,000 individuals had both, a breathing-related sleep disorder and a major depressive disorder, with up to 20% of the subjects presenting with one of these disorders also having the other. In some populations, depending on age, gender and other demographic and health characteristics, the prevalence of both disorders may be even higher: OSA may affect more than 50% of individuals over the age of 65, and significant depressive symptoms may be present in as many as 26% of a community-dwelling population of older adults. In clinical practice, the presence of depressive symptomatology is often considered in patients with OSA, and may be accounted for and followed-up when considering treatment approaches and response to treatment. On the other hand, sleep problems and specifically OSA are rarely assessed on a regular basis in patients with a depressive disorder. However, OSA might not only be associated with a depressive syndrome, but its presence may also be responsible for failure to respond to appropriate pharmacological treatment. Furthermore, an undiagnosed OSA might be exacerbated by adjunct treatments to antidepressant medications, such as benzodiazepines. Increased awareness of the relationship between depression and OSA might significantly improve diagnostic accuracy as well as treatment outcome for both disorders. In this review, we will summarize important findings in the current literature regarding the association between depression and OSA, and the possible mechanisms by which both disorders interact. Implications for clinical practice will be discussed.

    The videoradiographic examination described was designed for habitual snorers and sleep apnea syndrome (SAS) patients and was performed during wakefulness and sleep. During wakefulness the purpose was to reveal any dysfunction in deglutiton and speech as well as morphologic abnormalities. The purpose during sleep, which usually was induced by low-dose midazolam intravenously, was to reveal the site and form of obstruction in obstructive sleep apnea patients and the site of snoring in habitual snorers. The preoperative results of 104 patients are presented. In 57 patients who had apneas, the occurrence and type of apnea could be determined. A continuous recording over some minutes gave a rough estimate of the degree of SAS and mean duration of apnea. Although much information on SAS can be obtained by this method, it cannot replace polygraphic sleep recording in the investigation of habitual snorers and SAS patients. However, these 2 methods are complementary and can be performed simultaneously as polygraphic videoradiography. (orig.).

    The upper airway narrowing and changes in head posture and their relationship with apnea severity in patients with obstructive sleep apnea (OSA) were investigated. In 86 male OSA patients and 37 healthy men, one-night polysomnographic examination was performed and a lateral cephalogram by digital image processing system was taken in each subject. Fifteen variables concerning the upper airway dimensions, area and head postures were measured by using a computer software (NIH Image). The results showed that upper airway dimensions in the OSA group at all levels were significantly smaller than those in the control group and the results hold true when the age and body mass index were well controlled in these two groups. Significant forward inclination of the cervical column was found in the patients with an apnea index (AI) greater than 35episodes/h. And changes in the head posture variables in the whole study group were significantly correlated with AI and airway dimensions at various levels. It was suggested that there exist significant and extensive upper airway narrowing in OSA patients even in upright position and awake state; And as the apnea severity progresses, patients may assume certain compensatory head postures in an attempt to maintain an adequate airway patency.

  8. Pathogenic Roles of the Carotid Body Inflammation in Sleep Apnea

    2014-01-01

    Full Text Available Breathing difficulties in sleep are a hallmark of sleep-disordered breathing commonly observed in patients with sleep disorders. The pathophysiology of sleep apnea is in part due to an augmented activity of the carotid body chemoreflex. Arterial chemoreceptors in the carotid body are sensitive to inflammatory cytokines and immunogenic molecules in the circulation, because cytokine receptors are expressed in the carotid body in experimental animals and human. Intriguingly, proinflammatory cytokines are also locally produced and released in the carotid body. Also, there are significant increases in the expression of proinflammatory cytokines, cytokine receptors, and inflammatory mediators in the carotid body under hypoxic conditions, suggesting an inflammatory response of the carotid body. These upregulated cytokine signaling pathways could enhance the carotid chemoreceptor activity, leading to an overactivity of the chemoreflex adversely effecting breathing instability and autonomic imbalance. This review aims to summarize findings of the literature relevant to inflammation in the carotid body, with highlights on the pathophysiological impact in sleep apnea. It is concluded that local inflammation in the carotid body plays a pathogenic role in sleep apnea, which could potentially be a therapeutic target for the treatment of the pathophysiological consequence of sleep apnea.

    Full Text Available INTRODUCTION: Upper airway nerve and muscle damage associated with obstructive sleep apnea may impair the strength and dynamics of pharyngeal and esophageal contractions during swallowing. OBJECTIVE: To evaluate the presence of alterations in pharyngoesophageal manometry in patients with obstructive sleep apnea with and without oropharyngeal dysphagia. METHODS: This study prospectively evaluated 22 patients with obstructive sleep apnea without spontaneous complaints of dysphagia, using a questionnaire, fiberoptic endoscopic evaluation of swallowing, and pharyngoesophageal manometry, including measurement of the upper and lower esophageal sphincter pressures and mean pharyngeal pressures at three levels during swallowing. RESULTS: The dysphagia group consisted of 17 patients (77.3% in whom swallowing abnormalities were detected on fiberoptic endoscopic evaluation of swallowing (n = 15; 68.2% and/or in the questionnaire (n = 7; 31.8%. The five remaining cases comprised a control group without oropharyngeal dysphagia. In all cases of abnormalities on fiberoptic endoscopic evaluation of swallowing, there was premature bolus leakage into the pharynx. There was no statistically significant difference between the groups regarding any of the pharyngoesophageal manometry measurements, age, or severity of obstructive sleep apnea. CONCLUSION: Pharyngoesophageal manometry detected no statistically significant difference between the groups with and without oropharyngeal dysphagia.

OSA is an independent risk factor for a variety of cardiovascular diseases. Endothelial injury could be the pivotal determinant in the development of cardiovascular pathology in OSA. Endothelial damage ultimately represents a dynamic balance between the magnitude of injury and the capacity for repair. Bone marrow–derived endothelial progenitor cells (EPCs within adult peripheral blood present a possible means of vascular maintenance that could home to sites of injury and restore endothelial integrity and normal function. Methods: We summarized pathogenetic mechanisms of OSA and searched for available studies on numbers and functions of EPCs in patients with OSA to explore the potential links between the numbers and functions of EPCs and OSA. In particular, we tried to elucidate the molecular mechanisms of the effects of OSA on EPCs. Conclusion: Intermittent hypoxia cycles and sleep fragmentation are major pathophysiologic characters of OSA. Intermittent hypoxia acts as a trigger of oxidative stress, systemic inflammation, and sympathetic activation. Sleep fragmentation is associated with a burst of sympathetic activation and systemic inflammation. In most studies, a reduction in circulating EPCs has

    Abstract Pediatric obstructive sleep apnea (OSA) is associated with chronic systemic inflammation and with cognitive impairments. This study aimed to investigate the status of proinflammatory cytokines, particularly interleukin 17 (IL-17) and interleukin 23 (IL-23) and cognition in pediatric OSA. Controls and OSA children participated in the study. Exclusion criteria were adenotonsillectomy, heart, neurological and severe psychiatric diseases, craniofacial syndromes, and obesity. Polysomnogram was followed by serum testing for inflammatory markers and neurocognitive tests such as continuous performance task (CPT) and Wisconsin card sorting test, questionnaires, analyses of plasma high-sensitivity C-reactive protein (HS-CRP), tumor necrosis factor alpha (TNF-α), interleukin 1 (IL-1), interleukin 6 (IL-6), IL-17, and IL-23. Seventy-nine, 4 to 12-year-old subjects in 2 groups ended the study: 47 nonobese OSA children (mean age = 7.84 ± 0.56 years, body mass index [BMI] = 16.95 ± 0.47 kg/m2, BMI z-score = 0.15 ± 0.21, and mean apnea–hypopnea index [AHI] = 9.13 ± 1.67 events/h) and 32 healthy control children (mean age = 7.02 ± 0.65 years, with BMI = 16.55 ± 0.58 kg/m2, BMI z-score = −0.12 ± 0.27, and mean AHI = 0.41 ± 0.07 event/h) were enrolled. Serum cytokine analyses showed significantly higher levels of HS-CRP, IL-17, and IL-23 in OSA children (P = 0.002, P = 0.024, and P = 0.047). Regression test showed significant influence of HS-CRP, TNF-α, IL-6, IL-17, and specifically IL-23, with the continuous performance test and Wisconsin card sorting test. OSA children have abnormal levels of IL-17, an interleukin related to T helper 17 cells, a T helper cell involved in development of autoimmunity and inflammation. This high expression level may contribute to the complications of pediatric OSA; we also found a significant influence of inflammatory cytokines, particularly IL-23, on abnormal neurocognitive testing.

    Study Objective: Opioids are associated with higher risk for ataxic breathing and sleep apnea. We conducted a systematic literature review and meta-analysis to assess the influence of long-term opioid use on the apnea-hypopnea and central apnea indices (AHI and CAI, respectively). Methods: A systematic review protocol (Cochrane Handbook guidelines) was developed for the search and analysis. We searched Embase, Medline, ACP Journal Club, and Cochrane Database up to November 2014 for three topics: (1) narcotics, (2) sleep apnea, and (3) apnea-hypopnea index. The outcome of interest was the variation in AHI and CAI in opioid users versus non-users. Two reviewers performed the data search and extraction, and disagreements were resolved by discussion. Results were combined by standardized mean difference using a random effect model, and heterogeneity was tested by χ2 and presented as I2 statistics. Results: Seven studies met the inclusion criteria, for a total of 803 patients with obstructive sleep apnea (OSA). We compared 2 outcomes: AHI (320 opioid users and 483 non-users) and 790 patients with CAI (315 opioid users and 475 non-users). The absolute effect size for opioid use was a small increased in apnea measured by AHI = 0.25 (95% CI: 0.02–0.49) and a medium for CAI = 0.45 (95% CI: 0.27–0.63). Effect consistency across studies was calculated, showing moderate heterogeneity at I2 = 59% and 29% for AHI and CAI, respectively. Conclusions: The meta-analysis results suggest that long-term opioid use in OSA patients has a medium effect on central sleep apnea.

    Background Obstructive sleep apnea is associated with an increased risk of cardiovascular events; whether treatment with continuous positive airway pressure (CPAP) prevents major cardiovascular events is uncertain. Methods After a 1-week run-in period during which the participants used sham CPAP, we randomly assigned 2717 eligible adults between 45 and 75 years of age who had moderate-to-severe obstructive sleep apnea and coronary or cerebrovascular disease to receive CPAP treatment plus usual care (CPAP group) or usual care alone (usual-care group). The primary composite end point was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for unstable angina, heart failure, or transient ischemic attack. Secondary end points included other cardiovascular outcomes, health-related quality of life, snoring symptoms, daytime sleepiness, and mood. Results Most of the participants were men who had moderate-to-severe obstructive sleep apnea and minimal sleepiness. In the CPAP group, the mean duration of adherence to CPAP therapy was 3.3 hours per night, and the mean apnea-hypopnea index (the number of apnea or hypopnea events per hour of recording) decreased from 29.0 events per hour at baseline to 3.7 events per hour during follow-up. After a mean follow-up of 3.7 years, a primary end-point event had occurred in 229 participants in the CPAP group (17.0%) and in 207 participants in the usual-care group (15.4%) (hazard ratio with CPAP, 1.10; 95% confidence interval, 0.91 to 1.32; P=0.34). No significant effect on any individual or other composite cardiovascular end point was observed. CPAP significantly reduced snoring and daytime sleepiness and improved health-related quality of life and mood. Conclusions Therapy with CPAP plus usual care, as compared with usual care alone, did not prevent cardiovascular events in patients with moderate-to-severe obstructive sleep apnea and established cardiovascular disease.

    Current solutions of sleep apnea diagnosis require the patient to undergo overnight studies at a specialized sleep laboratory. Due to such inconvenience and high cost, millions of sleep apnea patients remain undiagnosed and thus untreated. Based on a micro-electro-mechanical systems (MEMS) sensor and an effective apnea detection algorithm, we propose a low-cost single-channel apnea screening solution applicable in the comfort of patients' homes. A prototype device was designed and assembled including a MEMS sensor for measuring the patient's nasal air flows, and a time-domain signal processing IC for apnea detection and autonomous scoring. The IC chip was fabricated in standard 0.5- μm CMOS technology. The proposed device was tested for both respiratory rhythm detection and sleep apnea screening under clinical environment. Apnea-hypopnea indices (AHI) were scored to indicate severity of sleep apnea conditions. Test results suggest that the proposed device can be a valuable screening solution for the broader public with undiagnosed apnea conditions.

    Background and objectives Obstructive sleep apnea is associated with significantly increased cardiovascular morbidity and mortality. Fluid overload may promote obstructive sleep apnea in patients with ESRD through an overnight fluid shift from the legs to the neck soft tissues. Body fluid shift and severity of obstructive sleep apnea before and after hemodialysis were compared in patients with ESRD. Design, setting, participants, & measurements Seventeen patients with hemodialysis and moderate to severe obstructive sleep apnea were included. Polysomnographies were performed the night before and after hemodialysis to assess obstructive sleep apnea, and bioimpedance was used to measure fluid overload and leg fluid volume. Results The mean overnight rostral fluid shift was 1.27±0.41 L prehemodialysis; it correlated positively with fluid overload volume (r=0.39; P=0.02) and was significantly lower posthemodialysis (0.78±0.38 L; P<0.001). There was no significant difference in the mean obstructive apnea-hypopnea index before and after hemodialysis (46.8±22.0 versus 42.1±18.6 per hour; P=0.21), but obstructive apnea-hypopnea index was significantly lower posthemodialysis (−10.1±10.8 per hour) in the group of 12 patients, with a concomitant reduction of fluid overload compared with participants without change in fluid overload (obstructive apnea-hypopnea index +8.2±16.1 per hour; P<0.01). A lower fluid overload after hemodialysis was significantly correlated (r=0.49; P=0.04) with a lower obstructive apnea-hypopnea index. Fluid overload—assessed by bioimpedance—was the best predictor of the change in obstructive apnea-hypopnea index observed after hemodialysis (standardized r=−0.68; P=0.01) in multivariate regression analysis. Conclusions Fluid overload influences overnight rostral fluid shift and obstructive sleep apnea severity in patients with ESRD undergoing intermittent hemodialysis. Although no benefit of hemodialysis on obstructive sleep apnea severity

    Full Text Available Amy Atkeson, Sanja JelicDivision of Pulmonary, Allergy, and Critical Care Medicine, Columbia University College of Physicians and Surgeons, New York, NYAbstract: Endothelial activation and inflammation are important mediators of accelerated atherogenesis and consequent increased cardiovascular morbidity in obstructive sleep apnea (OSA. Repetitive episodes of hypoxia/reoxygenation associated with transient cessation of breathing during sleep in OSA resemble ischemia/reperfusion injury and may be the main culprit underlying endothelial dysfunction in OSA. Additional factors such as repetitive arousals resulting in sleep fragmentation and deprivation and individual genetic suseptibility to vascular manifestations of OSA contribute to impaired endothelial function in OSA. The present review focuses on possible mechanisms that underlie endothelial activation and inflammation in OSA.Keywords: endothelial, obstructive sleep apnea, inflammation, dysfunction

    Full Text Available Obstructive sleep apnea (OSA, characterized by recurrent upper airway (UA collapse during sleep, is associated with significant morbidity and disorders. Polysomnogram is employed in the evaluation of OSA and apnea-hypopnea number per hour reflects severity. For normal breathing, it is essential that the collapsible UA is patent. However, obstruction of the UA is quite common in adults and infants. Normally, important reflex mechanisms defend against the UA collapse. The muscle activity of UA dilators, including the genioglossus, tensor palatini (TP, and pharyngeal constrictors, is due to the integrated mechanism of afferent sensory input → to motor function. Snoring is harsh breathing to prevent UA obstruction. Unfortunately, snoring vibrations, pharyngeal suction collapse, negative pressure, and hypoxia cause pathological perturbations including dysfunctional UA afferent sensory activity. The current paper posits that peripheral sensory stimulation paradigm, which has been shown to be efficacious in improving several neurological conditions, could be an important therapeutic strategy in OSA also.

    This paper presents use of an unobtrusive pressure sensor array for simulated central apnea detection. Data was collected from seven volunteers who performed a series of regular breathing and breath holding exercises to simulate central apneas. Results of the feature extraction from the breathing signals show that breathing events may be differentiated with epoch based variance calculations. Two approaches were considered: the single sensor approach and the multisensor vote approach. The multisensor vote approach can decrease false positives and increase the value of Matthew's Correlation Coefficient. The effect of lying position on correct classification was investigated by modifying the multisensor vote approach to reduce false positives segments caused by the balistocardiogram signal and as such increase sensitivity while maintaining a low false positive rate. Intersubject classification results had low variability in both approaches. PMID:19964320

  5. MR imaging evaluation of neck anatomy in sleep apnea

    International Nuclear Information System (INIS)

    Neck anatomy was evaluated by MR imaging in sleep apnea patients and healthy volunteers. The fascial layers of the neck divide the neck into an inner rigid compartment (muscle groups, vertebrae, and pharynx) and an outer flaccid compartment (skin, subcutaneous fat). Although the flaccid compartment doubled in cross-sectional area in patients with sleep apnea, the area of the rigid compartment also increased by over 30% relative to the area in healthy volunteers, resulting in airway narrowing. Rigid compartment enlargement resulted from an increase in the bulk of muscular groups, as well as from increased intermuscular fat. The epiglottis was not enlarged, while the volume of the tongue increased proportionately with the rigid compartment. No significant changes were detected in the relaxation times of either muscle or fat

    Full Text Available A 36-year-old male from an urban middleclass family with strained relationship among family members was referred from a corporate hospital for further management of psychological problem. As he was attempting suicide repeatedly, Electroconvulsive Therapy (ECT was planned. After preoperative assessment and preparation, modified ECT was done with thiopentone and 0.5 mg/kg of suxamethonium. Apnea following suxamethonium was prolonged for 2 hours. Subsequent enquiry revealed that patient was treated for organophosphate poisoning and was on ventilator support for 15 days. This was concealed by the relatives. On searching patient previous records, Butyrylcholinesterase levels were very low, i.e., 350 u/l (normal reference range is 5 500 - 12 500 u/l. Prolonged suxamethonium apnea should be anticipated in patients with recent history of organophosphate poisoning; it is advisable to estimate the levels of butyrylcholinesterase and avoid suxamethonium in patients with low enzyme levels.

    AIM: To assess the relationship between severity of gastroesophageal reflux disease and apnea-hypopnea index (AHI) as an indicator of the severity of obstructive sleep apnea.METHODS: Data of 57 patients with proven obstructive sleep apnea and gastroesophageal reflux disease were analyzed. Patients were divided into two groups according to severity of the sleep apnea: "mild-moderate" (A)-AHI ≥5-30, n = 27, "severe" (B)-AHI >30, n = 30. All patients underwent apnea monitoring during the night, upper panendoscopy and were asked about typical reflux symptoms.RESULTS: All examined patients in both groups showed a significant overweight and there was a positive correlation between body mass index and the degree of sleep apnea (P = 0.0002). The occurence of erosive reflux disease was significantly higher in "severe" group (P = 0.0001).Using a logistic regression analysis a positive correlation was found between the endoscopic severity of reflux disease and the AHI (P = 0.016). Forty-nine point five percent of the patients experienced the typical symptoms of reflux disease at least three times a week and there was no significant difference between the two groups.CONCLUSION: A positive correlation can be found between the severity of gastroesophageal reflux disease and obstructive sleep apnea.

    The contribution of apnea to chronic hypercapnia in obstructive sleep apnea (OSA) has not been clarified. Using a model (D. M. Rapoport, R. G. Norman, and R. M. Goldring. J. Appl. Physiol. 75: 2302-2309, 1993), we previously illustrated failure of CO(2) homeostasis during periodic breathing resulting from temporal dissociation between ventilation and perfusion ("temporal V/Q mismatch"). This study measures acute kinetics of CO(2) during periodic breathing and addresses interapnea ventilatory compensation for maintenance of CO(2) homeostasis in 11 patients with OSA during daytime sleep (37-171 min). Ventilation and expiratory CO(2) and O(2) fractions were measured on a breath-by-breath basis by means of a tight-fitting full facemask. Calculations included CO(2) excretion, metabolic CO(2) production, and CO(2) balance (metabolic CO(2) production - exhaled CO(2)). CO(2) balance was tabulated for each apnea/hypopnea event-interevent cycle and as a cumulative value during sleep. Cumulative CO(2) balance varied (-3,570 to +1,388 ml). Positive cumulative CO(2) balance occurred in the absence of overall hypoventilation during sleep. For each cycle, positive CO(2) balance occurred despite increased interevent ventilation to rates as high as 45 l/min. This failure of CO(2) homeostasis was dependent on the event-to-interevent duration ratio. The results demonstrate that 1) periodic breathing provides a mechanism for acute hypercapnia in OSA, 2) acute hypercapnia during periodic breathing may occur without a decrease in average minute ventilation, supporting the presence of temporal V/Q mismatch, as predicted from our model, and 3) compensation for CO(2) accumulation during apnea/hypopnea may be limited by the duration of the interevent interval. The relationship of this acute hypercapnia to sustained chronic hypercapnia in OSA remains to be further explored. PMID:10642388

    Obstructive sleep apnea (OSA) is a common and serious health issue that is strongly associated with excess weight. Exercise may be an effective mechanism for reducing the severity of OSA both in association with, and independent of, reduction in body weight. As such, increased exercise has been suggested as a potential intervention for OSA, particularly for patients with mild to moderate clinical severity. However, it is unknown how ready to engage in exercise patients with OSA are. Self-repo...

    Depression and sleep disorders are more frequent in patients on maintenance hemodialysis (HD) than the general population, and are associated with reduced quality of life and increased mortality risk. The purpose of this study was to assess the prevalence of depression, sleep apnea, insomnia in patients on HD as well as depression in their primary caregiver and to correlate these with the demographic profile. A cross-sectional study was conducted among 69 patients on maintenance HD for more than 3 months. There was high p revalence of depression (47.8%), insomnia (60.9%), increased risk of sleep apnea (24.6%) and depression in caregiver (31.9%). Depression was significantly more in patients with low monthly income (P=0.03), those on dialysis for more than 1 year (P=0.001) and the unemployed (P=0.009). High-risk patients for sleep apnea tended to be males with low monthly income (P=0.02). Insomnia was significantly higher in patients who were on dialysis for more than 1 year (P=0.003).

    PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

    Full Text Available OBJECTIVE: Obstructive sleep apnea syndrome (OSAS is characterized by nocturnal repetitive apnea episodes. Periodic limb movements (PLMs is nocturnal, stereotypic, repetitive movements of the lower extremities. The aim of this study was to investigate the presence of periodic limb movements in OSAS patients and correlation of PLM with OSAS severity. METHODS: One hundred and forty one OSAS suspected patients was enrolled into the study. All subjects’ blood pressure, heart rate measurements and neurologic examinations were made by the same neurologist. Sociodemographic characteristics were recorded. One night polysomnography (PSG was performed to all patients and results were analyzed. Apnea Hypopnea Index (AHI ≥ 5 subjects were accepted as OSAS, and PLM Index (PLMI ≥ 5 subjects were accepted as having PLM. RESULTS: One hundred and two patients were diagnosed as OSAS. The control group consisted of 39 patients who had normal polysomnographic findings. OSAS patients’ were older and body mass index (BMI were higher than the control group. Systolic blood pressure was higher in OSAS group. Alcohol use was determined as a risk factor for OSAS. PLM were more common in OSAS group than the control group (% 30,3 - % 10,2. PLM frequency was associated with the severity of OSAS. CONCLUSION: In OSAS patients presence of PLM was related with OSAS severity, higher systolic and diastolic blood pressure and REM sleep depletion. PLM in OSAS patients could be regarded as an indicator of disease severity and also could aware clinician for increased complication rates.

    Full Text Available Obstructive Sleep Apnea Syndrome (OSAS is a sleep disorder characterised by repetitive episodes of upper airway obstruction (apnea or reduced airflow (hypopnoea despite persistent respiratory effort. Apnea is defined as the cessation of breathing for at least 10 seconds during sleep, while hypopnoea is defined as at least 30% reduction in airflow for 10 seconds associated with oxygen desaturation and sleep fragmentation. The presence in the general population is about 4%. The principal symptoms are: excessive daytime sleepiness (EDS, snoring, dry throat, morning headache, night sweats, gastro-esophageal reflux, and increased blood pressure.Long term complications can be: increased cardio-cerebrovascular risk and cognitive impairment such as deficiency in attention, vigilance, visual abilities, thought, speech, perception and short term memory.Continuous Positive Airway Pressure (CPAP is currently the best non-invasive therapy for OSAS.CPAP guarantees the opening of upper airways using pulmonary reflexive mechanisms increasing lung volume during exhalation and resistance reduction, decreasing electromyografical muscular activity around airways.The causes of cognitive impairments and their possible reversibility after CPAP treatment have been analysed in numerous studies. The findings, albeit controversial, show that memory, attention and executive functions are the most compromised cognitive functions.The necessity of increasing the patient compliance with ventilotherapy is evident, in order to prevent cognitive deterioration and, when possible, rehabilitate the compromised functions, a difficult task for executive functions.

    Full Text Available Objective: The aim of this study is to investigate the existence of erectile dysfunction in patients with obstructive sleep apnea syndrome (OSAS in which the other possible causes of erectile dysfunction were eliminated.Material and Methods: The study group consisted of 24 patients diagnosed as OSAS with polysomnographic evaluation, and 15 non-apneic controls (mean age; 41.0±8.8 and 42.3±7.9 year respectively whose comorbidities which might be associated with erectile dysfunction were excluded. Daytime sleepiness was evaluated by Epworth Sleepiness Scale (ESS and measurement of erectile function was performed by International Index of Erectile Function.Results: The rate of erectile dysfunction in OSAS and control groups were 54.2% and 33.3% respectively (p=0.204. The difference between mean erectile function scores of patient and control groups was non-significant (26.1±4.5 and 26.3±4.3 respectively, p=0.900. There was no correlation between erectile function scores and apnea hypnoea index (r=-0.140; p=0.395.Conclusion: Findings obtained from this study suggest that the high incidence of erectile dysfunction reported in OSAS patients seems to be related with concomitant comorbidities such as diabetes, atherosclerosis and neuroendocrine disorders rather than sleep apnea.

    The first of these reviews described the physiological factors defining the limits of static apnea, while the second examined performance in apneic distance swimming. This paper reviews the factors determining performance in depth disciplines, where hydrostatic pressure is added to the stressors associated with apnea duration and physical work. Apneic duration is essential for performance in all disciplines, and is prolonged by any means that increases gas storage or tolerance to asphyxia or reduces metabolic rate. For underwater distance swimming, the main challenge is to restrict metabolism despite the work of swimming, and to redirect blood flow to allow the most vital functions. Here, work economy, local tissue energy and oxygen stores, anaerobic capacity of the muscles, and possibly technical improvements will be essential for further development. In the depth disciplines, direct pressure effects causing barotrauma, the narcotic effects of gases, decompression sickness (DCS) and possibly air embolism during ascent need to be taken into account, as does the risk of hypoxia when the dive cannot be rapidly interrupted before the surface is reached again. While in most deep divers apneic duration is not the main limitation thus far, greater depths may call for exceptionally long apneas and slower ascents to avoid DCS. Narcotic effects may also affect the ultimate depth limit, which the divers currently performing 'constant weight with fins' dives predict to be around 156 metres' sea water. To reach these depths, serious physiological challenges have to be met, technical developments needed and safety procedures developed concomitantly. PMID:22183699

  8. Cardiovascular responses induced by obstructive apnea are enhanced in hypertensive rats due to enhanced chemoreceptor responsivity.

    Directory of Open Access Journals (Sweden)

    Juliana M M Angheben

    Full Text Available Spontaneously hypertensive rats (SHR, like patients with sleep apnea, have hypertension, increased sympathetic activity, and increased chemoreceptor drive. We investigated the role of carotid chemoreceptors in cardiovascular responses induced by obstructive apnea in awake SHR. A tracheal balloon and vascular cannulas were implanted, and a week later, apneas of 15 s each were induced. The effects of apnea were more pronounced in SHR than in control rats (Wistar Kyoto; WKY. Blood pressure increased by 57±3 mmHg during apnea in SHR and by 28±3 mmHg in WKY (p<0.05, n = 14/13. The respiratory effort increased by 53±6 mmHg in SHR and by 34±5 mmHg in WKY. The heart rate fell by 209±19 bpm in SHR and by 155±16 bpm in WKY. The carotid chemoreceptors were then inactivated by the ligation of the carotid body artery, and apneas were induced two days later. The inactivation of chemoreceptors reduced the responses to apnea and abolished the difference between SHR and controls. The apnea-induced hypertension was 11±4 mmHg in SHR and 8±4 mmHg in WKY. The respiratory effort was 15±2 mmHg in SHR and 15±2 mmHg in WKY. The heart rate fell 63±18 bpm in SHR and 52±14 bpm in WKY. Similarly, when the chemoreceptors were unloaded by the administration of 100% oxygen, the responses to apnea were reduced. In conclusion, arterial chemoreceptors contribute to the responses induced by apnea in both strains, but they are more important in SHR and account for the exaggerated responses of this strain to apnea.

    In competitive apnea divers, the nutritional demands may be essentially different from those of, for example, endurance athletes, where energy resources need to be maximised for successful performance. In competitive apnea, the goal is instead to limit metabolism, as the length of the sustainable apneic period will depend to a great extent on minimising oxygen consumption. Many but not all elite divers fast before performing static apnea in competition. This may increase oxygen consumption as mainly lipid stores are metabolised but could also have beneficial effects on apneic duration. Our aim was to determine the effect of over-night fasting on apnea performance. Six female and seven male divers performed a series of three apneas after eating and fasting, respectively. The series consisted of two 2-min apneas spaced by 3 min rest and, after 5 min rest, one maximal effort apnea. Apneas were performed at supine rest and preceded by normal respiration and maximal inspiration. Mean (± SD) time since eating was 13 h (± 2 h 43 min) for the fasting and 1 h 34 min (± 33 min) for the eating condition (P eating (Peating and ETCO2 was lower in the fasting condition (P eating conditions (P eating (P eating (P < 0.01). The 22% longer apnea duration after fasting with analogous end apnea SaO2 levels suggests that fasting is beneficial for static apnea performance in elite divers, likely via metabolism-limiting mechanisms. The oxygen-conserving effect of the more pronounced diving response and possibly other metabolism-limiting mechanisms related to fasting apparently outweigh the enhanced oxygen consumption caused by lipid metabolism.

We report the case of a 44-year-old female with CM-I who was referred to our sleep laboratory for suspected sleep apnea. The patient had undergone decompressive surgery 3 years prior. An arterial blood gas analysis showed hypercapnia. Polysomnography showed a respiratory disturbance index of 108 events/h, and all were central apnea events. Treatment with adaptive servo-ventilation was initiated, and central apnea was resolved. This report demonstrates the efficacy of servo-ventilation in the treatment of central sleep apnea syndrome associated with alveolar hypoventilation in a CM-I patient with a history of decompressive surgery.

    Obstructive sleep apnea represents a large burden of disease to the general population and may compromise patient quality of life; workplace and automotive safety; and metabolic, cardiovascular, and neurocognitive health. The disease is characterized by repetitive cycles of upper airway collapse resulting from a lack of pharyngeal airway structural support and loss of muscle tone among upper airway dilators. Polysomnography serves as the gold standard for diagnosis of obstructive sleep apnea and the apnea-hypopnea index is the most commonly used metric for quantifying disease severity. Conservative treatments include lifestyle modification, continuous positive airway pressure treatment, and dental appliance therapy. Surgical treatment options include pharyngeal and facial skeletal surgery. Maxillomandibular advancement has been shown to be the most effective surgical approach for multilevel expansion of the upper airway and may significantly reduce an obstructive sleep apnea patient's apnea-hypopnea index. Patient age, obesity, and the degree of maxillary advancement may be key factors contributing to treatment success. PMID:27673521

    Snoring is extremely common in the general population and when irregular may indicate the presence of obstructive sleep apnea. We analyze the overnight sequence of wave packets --- the snore sound --- recorded during full polysomnography in patients referred to the sleep laboratory due to suspected obstructive sleep apnea. We hypothesize that irregular snore, with duration in the range between 10 and 100 seconds, correlates with respiratory obstructive events. We find that the number of irregular snores --- easily accessible, and quantified by what we call the snore time interval index (STII) --- is in good agreement with the well-known apnea-hypopnea index, which expresses the severity of obstructive sleep apnea and is extracted only from polysomnography. In addition, the Hurst analysis of the snore sound itself, which calculates the fluctuations in the signal as a function of time interval, is used to build a classifier that is able to distinguish between patients with no or mild apnea and patients with mod...

    In this 71-year-old man diagnosed as obstructive sleep apnea syndrome initially, the apnea-hypopnea index in polysomnography was 31.3/hour. He started auto-adjusted continuous positive airway pressure (auto-CPAP) treatment in July 2005 but developed congestive heart failure in December 2007. Pulmonary arterial pressure (PAP), estimated by echocardiography, was 71 mmHg. In January 2008, during simplified sleep examination with a breath-movement sensor under auto-CPAP, many central-type apneas were recognized. After replacing auto-CPAP with adaptive servo-ventilation (ASV), the apnea-hypopnea index was 5.3/hour and PAP became 36 mmHg after 3 months. It was thought that the increase of PAP was due to long-term inadequate use of auto-CPAP.

    Full Text Available Autonomic dysfunction is recognized to contribute to cardiovascular consequences in obstructive sleep apnea/hypopnea syndrome (OSAHS patients who present predominant cardiovascular sympathetic activity that persists during wakefulness. Here, we examined 1 the factors that influence sympathetic cardiac modulation in response to apneas/hypopneas; and 2 the influence of autonomic activity during apneas/hypopneas on CA. Sixteen OSAHS patients underwent in-hospital polysomnography. RR interval (RR and RR spectral analysis using wavelet transform were used to study parasympathetic (high frequency power: HF(WV and sympathetic (low frequency power: LF(WV and LF(WV/HF(WV ratio activity before and after apnea/hypopnea termination. Autonomic cardiac modulations were compared according to sleep stage, apnea/hypopnea type and duration, arterial oxygen saturation, and presence of CA. At apnea/hypopnea termination, RR decreased (p<0.001 while LF(WV (p = 0.001 and LF(WV/HF(WV ratio (p = 0.001 increased. Only RR and LF(WV/HF(WV ratio changes were higher when apneas/hypopneas produced CA (p = 0.030 and p = 0.035, respectively or deep hypoxia (p = 0.023 and p = 0.046, respectively. Multivariate statistical analysis showed that elevated LF(WV (p = 0.006 and LF(WV/HF(WV ratio (p = 0.029 during apneas/hypopneas were independently related to higher CA occurrence. Both the arousal and hypoxia processes may contribute to sympathetic cardiovascular overactivity by recurrent cardiac sympathetic modulation in response to apneas/hypopneas. Sympathetic overactivity also may play an important role in the acute central response to apneas/hypopneas, and in the sleep fragmentation.

    Data from animal and human studies provide a biological plausibility to the notion that obstructive sleep apnea activates pathways that lead to insulin resistance, atherosclerosis and hypertension. Sleep apnea thus activates the same pathways as does obesity. That obstructive sleep apnea is a risk factor for cardiovascular disease is supported by epidemiological association studies. Longitudinal cohort studies also provide evidence that patients with untreated severe sleep apnea have an increased rate of cardiovascular events. But these studies, while highly suggestive, do not provide the evidence needed to convince the skeptic. This would only be obtained by randomized treatment trials with hard cardiovascular endpoints such as cardiac events and deaths. While such studies are in the planning stages, they will be challenging. There are issues about randomizing individuals with severe sleep apnea and excessive sleepiness into no therapy, since they are at known increased risk for car crashes. Thus, lack of therapy puts others on the road at risk as well as the subject with sleep apnea. There is, moreover, the concern that treating obstructive sleep apnea in very obese individuals will have little impact, since any effect of therapy for OSA will be overwhelmed by the effects of obesity itself. Data from randomized treatment trials for cardiovascular endpoints will likely not be available for many years. In the interim, physicians need to consider how to treat such patients. It is proposed that given that CPAP treatment for obstructive sleep apnea is highly effective and essentially totally safe, and that the evidence is suggestive that sleep apnea is a risk factor for cardiovascular disease, then we propose all patients with severe sleep apnea should be treated to reduce cardiovascular risk.

    Full Text Available OBJECTIVES: The aim of this study was to investigate neuropsychological performance and biomarkers of oxidative stress in patients with obstructive sleep apnea and the relationships between these factors. METHODS: This was an observational, cross-sectional study of 14 patients (36.0±6.5 years old with obstructive sleep apnea and 13 controls (37.3±6.9 years old. All of the participants were clinically evaluated and underwent full-night polysomnography as well as neuropsychological tests. Blood samples were used to assay superoxide dismutase, catalase, glutathione and homocysteine, as well as vitamins E, C, B11 and B12. RESULTS: The patients performed poorly relative to the controls on several neuropsychological tests, such as the attention test and tests of long-term memory and working memory/executive function. They also had lower levels of vitamin E (p<0.006, superoxide dismutase (p<0.001 and vitamin B11 (p<0.001, as well as higher concentrations of homocysteine (p<0.02. Serum concentrations of vitamin C, catalase, glutathione and vitamin B12 were unaltered. Vitamin E levels were related to performance in the backward digit span task (F = 15.9; p = 0.002 and this correlation remained after controlling for age and body mass index (F = 6.3, p = 0.01. A relationship between superoxide dismutase concentrations and executive non-perseveration errors in the Wisconsin Card Sorting Test (F = 7.9; p = 0.01 was also observed. CONCLUSIONS: Decreased levels of antioxidants and lower performance on the neuropsychological tasks were observed in patients with obstructive sleep apnea. This study suggests that an imbalance between antioxidants and pro-oxidants may contribute to neuropsychological alterations in this patient population.

    Full Text Available Odontoid fractures are typically associated with low rates of acute neurologic deficit and morbidity/mortality in nonelderly patients. In the patient in this case, traumatic injury triggered by a syncopal event led to a combined C1-C2 fracture and a fatal spinal cord injury with apnea, quadriplegia, and cardiovascular instability. We briefly review the anatomical basis for the pathophysiology of cardiac dysfunction following high-cervical spine injury and present an example of a worst-case scenario.

    Full Text Available Pediatric obstructive sleep apnea (OSA is not always resolved or improved with adenotonsillectomy. Persistent or complex cases of pediatric OSA may be due to sites of obstruction in the airway other than the tonsils and adenoids. Identifying these areas in the past has been problematic, and therefore, therapy for OSA in children who have failed adenotonsillectomy has often been unsatisfactory. Sleep endoscopy is a technique that can enable the surgeon to determine the level of obstruction in a sleeping child with OSA. With this knowledge, site-specific surgical therapy for persistent and complex pediatric OSA may be possible.

Patients with obstructive sleep apnea syndrome (OSAS have a tendency to develop coronary and cerebral atherosclerotic diseases. Objectives: The aim of the present study was to study copeptin levels in patients with obstructive sleep apnea and in a control group in order to determine whether copeptin could be used as a biomarker predicting the severity of OSAS and possible complications in this group. Methods: A total of 116 patients with OSAS, diagnosed by polysomnography, and 27 controls were included in the study. Blood samples were collected after overnight fasting, and copeptin levels were measured with enzyme-linked immunosorbent assay. Results: Copeptin levels were significantly higher in the OSAS group compared to control group (2,156±502; 1,845±500 pg/mL, respectively, P=0.004. Mean copeptin level of the patients having apnea-hypopnea index (AHI ≥30 was significantly higher than that of the patients having AHI <30 (2,392±415; 2,017±500 pg/mL, respectively, P<0.001. A multivariate regression analysis showed that copeptin level, (hazard ratio: 1.58; 95% confidence interval: 1.09–2.30 was a predictor of severe OSAS (P=0.016. Copeptin levels showed significant positive correlation with AHI (r=0.32; P<0.001, desaturation index (r=0.23; P=0.012, arousal index (r=0.24; P=0.010 and CRP (r=0.26; P=0.011 respectively. Conclusion: Copeptin levels are high in OSAS patients and copeptin is a potential marker for identifying patients with a high risk of early cardiovascular

    International Nuclear Information System (INIS)

    Obstructive sleep apnea (OSA) is characterized by recurrent upper airway obstruction occurring at the level of the pharynx during sleep. Although cephalometric analysis is an important method in the diagnosis of craniofacial deformities, CT and magnetic resonance imaging have been highlighted as the major imaging methods to investigate the possible causes of OSA, which, in most cases, is multifactorial. Magnetic resonance and CT both allow an excellent evaluation of the various anatomical planes of the site of obstruction, which enables better clinical assessment and surgical approach. This pictorial essay aims to describe the aspects that must be evaluated in the diagnostic imaging of patients presenting with the major predisposing factors for OSA. (author)

Vigilance and attentiveness are often impaired in OSA patients. In occupational medicine settings, subjective reports of sleepiness are notoriously inaccurate, making the identification of objective measures of vigilance potentially important for risk assessments of fitness for duty. In order to evaluate the effects of OSA on attentiveness and vigilance, we conducted a cross-sectional study to examine the association between OSA and psychomotor vigilance task (PVT performance.Methods: Patients attending sleep clinics for evaluation of possible sleep apnea were recruited. The subjects underwent either a standard overnight laboratory polysomnography or home sleep study. Subjective daytime sleepiness was assessed by Epworth sleepiness scale, and vigilance was tested using a portable device. The participants were asked to respond to the PVT signals using their dominant hand. Each PVT administration lasted 10 minutes, with stimuli signals appearing randomly at variable intervals of 2–10 seconds.Results: Mean age of the participants was 46±15 years, and mean body mass index was 34.3±9.8 kg/m2. Participants with higher Epworth scores had worse PVT performance (P<0.05.

    Insomnia is often comorbid with obstructive sleep apnea. It reduces positive airway pressure (PAP) therapy acceptance and adherence. Comorbid patients show greater daytime impairments and poorer health outcomes. The insomnia often goes undiagnosed, undertreated, or untreated. Pharmacotherapy is not recommended for long-term treatment. Although care should be taken administering behavioral therapies to patients with elevated sleepiness, cognitive behavior therapy for insomnia (CBTi) is an effective and durable nondrug therapy that reduces symptoms and may increase the effectiveness of PAP therapy. Sleep clinics should be alert to comorbid insomnia and provide adequate diagnostic tools and clinicians with CBTi expertise. PMID:27542883

For over 25 years, the primary treatment has been continuous positive airway pressure, which introduces a column of air that serves as a pneumatic splint for the upper airway, preventing the airway collapse that is the physiologic definition of this syndrome. However, issues with patient tolerance and unacceptable levels of treatment adherence motivated the exploration of other potential treatments. With greater understanding of the physiologic mechanisms associated with OSA, novel interventions have emerged in the last 5 years. The purpose of this article is to describe new treatments for OSA and associated complex sleep apnea. New approaches to complex sleep apnea have included adaptive servoventilation. There is increased literature on the contribution of behavioral interventions to improve adherence with continuous positive airway pressure that have proven quite effective. New non-surgical treatments include oral pressure devices, improved mandibular advancement devices, nasal expiratory positive airway pressure, and newer approaches to positional therapy. Recent innovations in surgical interventions have included laser-assisted uvulopalatoplasty, radiofrequency ablation, palatal implants, and electrical

    Sleep is important for children pertaining to their physical and mental growth. Obstructive sleep apnea syndrome (OSAS) in children has been shown to have different effects as compared to OSAS in adults, including deficits in cognition and neuropsychological functions, hyperactivity, ADHD, behavior problems, aggressive behavior, learning problems and nocturnal enuresis. Hypertrophy of the adenoids and tonsils is a major cause of OSAS in children; therefore, adenotonsillectomy may decrease the effects of OSAS pertaining to physical and mental growth. It is important to accurately diagnose and appropriately treat OSAS in children to prevent OSAS in their adulthood. PMID:27115764

    Background Many patients with obstructive sleep apnea syndrome (OSAS) have complicated with hypertension and may be prescribed with antihypertension medications to control their blood pressure. But whether antihypertension medications can also decrease arterial stiffness or control the blood pressure increasing following obstructive events is not well described. This study aimed to investigate whether antihypertensive medications can ameliorate the changes in arterial stiffness and blood pressure associated with OSA. Methods Sixty-one OSAS patients [13 women, 48 men, mean age (53.4±12.3) years], 26 normotensive patients (N), 7 hypertensive patients on no antihypertension medications (H), and 28 hypertensive patients on various combination antihypertension therapy (HM), were prospectively diagnosed with standard nocturnal polysomnography. Beat-to-beat blood pressure was continuously recorded from the radial artery by applanation tonometry during baseline sleep. As a measure of arterial stiffness, arterial augmentation index (AAI) was calculated as the ratio of augmented systolic blood pressure (SBP) to pulse pressure and expressed as a percentage for the following conditions: awakening, the first 10 ("early apnea") and last 10 ("late apnea") cardiac cycles of obstructive events (apnea or hypopnea), and the first 15 cardiac cycles following event termination ("post apnea") for all events with nadir O2 saturation ≤89%. Results Systolic blood pressure (SBP) post-apnea [(142.74±13.06) mmHg (N), (137.06±26.56) mmHg (H), (136.94±14.1) mmHg (HM)] was significantly increased from awakening [(135.76±14.76) mmHg (N), (135.58±23.17) mmHg (H), (129.77±14.00) mmHg (HM)], early apnea [(130.53±12.65) mmHg (N),(124.47±24.97) mmHg (H), (126.04±13.12) mmHg (HM)], and late apnea [(129.8±12.68) mmHg(N), (124.78±25.15) mmHg (H),(124.48±13.82) mmHg (HM)] respectively (P<0.001, repeated measures ANOVA).

    International Nuclear Information System (INIS)

    We attempted to determine the usefulness of high-speed MR imaging for evaluating the severity of sleep apnea syndrome (SAS) by comparing findings of pharyngeal obstruction obtained with high-speed MR with those of all-night polysomnography (PSG). A total of 33 patients with SAS underwent turbo-FLASH MR examination, while awake and after i.v. injection of hydroxyzine hydrochloride. Serial images were examined by cinemode. Pharyngeal findings on MR were divided into single-site obstruction (SO) at the velopharynx, multiple-site obstruction (MO), and no obstruction (NO). PSG findings were analyzed to determine the predominant type of apnea, severity as evaluated by an apnea index (AI), and the lowest SaO2 value during sleep. Seventy-five percent of the central apnea group had SO, and 70% of the mixed apneas had MO, while only 15% of the obstructed apneas had MO. The percentage of patients with severe SAS (AI of 20% or higher) was 48% for the SO, and 70% for the MO. The lowest SaO2 value tended to be low in the mixed apnea in the case of PSG, and tended to be low in the MO at MR examination. Analysis of pharyngeal dynamics using high-speed MR may provide some useful information for evaluating the severity of SAS. (orig.)

    Full Text Available Introduction: Patients with obstructive sleep apnea syndrome usually present with changes in upper airway morphology and/or body fat distribution, which may occur throughout life and increase the severity of obstructive sleep apnea syndrome with age. Objective: To correlate cephalometric and anthropometric measures with obstructive sleep apnea syndrome severity in different age groups. Methods: A retrospective study of cephalometric and anthropometric measures of 102 patients with obstructive sleep apnea syndrome was analyzed. Patients were divided into three age groups (≥20 and <40 years, ≥40 and <60 years, and ≥60 years. Pearson's correlation was performed for these measures with the apnea-hypopnea index in the full sample, and subsequently by age group. Results: The cephalometric measures MP-H (distance between the mandibular plane and the hyoid bone and PNS-P (distance between the posterior nasal spine and the tip of the soft palate and the neck and waist circumferences showed a statistically significant correlation with apnea-hypopnea index in both the full sample and in the ≥40 and <60 years age group. These variables did not show any significant correlation with the other two age groups (<40 and ≥60 years. Conclusion: Cephalometric measurements MP-H and PNS-P and cervical and waist circumfer- ences correlated with obstructive sleep apnea syndrome severity in patients in the ≥40 and <60 age group.

    Full Text Available OBJECTIVES: The aims of this study were to evaluate the correlation between oropharyngeal examination and objective palatine tonsil volume in snoring adults and verify the influence of the oropharyngeal anatomy, body mass index, age, and severity of obstructive sleep apnea on actual tonsil volume. In addition, we aimed to assess the influence of tonsil size on obstructive sleep apnea in adults. INTRODUCTION: Pharyngeal wall geometry is often altered in adults who have obstructive sleep apnea, and this might influence the findings of the oropharyngeal examination that, in turn, are the key factors when considering surgical management for this condition. Furthermore, the correlation between the actual tonsil volume and the severity of obstructive sleep apnea in adults is currently unknown. METHODS: We prospectively studied 130 patients with obstructive sleep apnea or primary snoring who underwent pharyngeal surgery with intraoperative measurement of tonsil volume. We compared tonsil volume with preoperative polysomnography, oropharyngeal examination, and anthropometric data. RESULTS: We found a significant correlation between actual tonsil volume and subjective tonsil grade. We also found a significant correlation between tonsil volume and the apnea-hypopnea index. Using a multivariate linear regression model, tonsil volume was found to be significantly correlated with age, body mass index, and oropharyngeal examination, but not with polysomnography. Clinically, only the rare tonsil grade IV was indicative of more severe obstructive sleep apnea. CONCLUSIONS: There is a strong correlation between clinical tonsil grade and objective tonsil volume in snoring adults, and this correlation exists regardless of the presence or severity of obstructive sleep apnea. Pharyngeal tissue volume likely reflects the body mass index rather than obstructive sleep apnea severity.

    This work describes the design of an algorithm for detecting apnea episodes, based on analysis of thorax respiratory effort signal. Inspiration and expiration time, and range amplitude of respiratory cycle were evaluated. For range analysis the standard deviation statistical tool was used over respiratory signal temporal windows. The validity of its performance was carried out in 8 records of Apnea-ECG database that has annotations of apnea episodes. The results are: sensitivity (Se) 73%, specificity (Sp) 83%. These values can be improving eliminating artifact of signal records.

    Characterizing respiratory rate variability (RRV) in humans during sleep is challenging, since it requires the analysis of respiratory signals over a period of several hours. These signals are easily distorted by movement and volitional inputs. We applied the method of spectral analysis to the nasal pressure transducer signal in 38 adults with no obstructive sleep apnea, defined by an apnea-hypopnea index sleep stages, including wakefulness. The nasal pressure transducer signal was acquired at 100 Hz and consecutive frequency spectra were generated for the length of the PSG with the Fast Fourier Transform. For each spectrum, we computed the amplitude ratio of the first harmonic peak to the zero frequency peak (H1/DC), and defined as RRV as (100 - H1/DC) %. RRV was greater during wakefulness compared to any sleep stage, including rapid-eye-movement. Furthermore, RRV correlated with the depth of sleep, being lowest during N3. Patients spent most their sleep time supine, but we found no correlation between RRV and body position. There was a correlation between respiratory rate and sleep stage, being greater in wakefulness than in any sleep stage. We conclude that RRV varies according to sleep stage. Moreover, spectral analysis of nasal pressure signal appears to provide a valid measure of RRV during sleep. It remains to be seen if the method can differentiate normal from pathological sleep patterns. PMID:27597768

    Purpose: The American Society of Anesthesia practice guidelines recommend that pediatric and adult patients who undergo ambulatory surgery be screened for obstructive sleep apnea (OSA). With this in mind, our objective was to assess the frequency of screening by anesthesia providers for the signs and symptoms of OSA in children undergoing surgery in an ambulatory setting. Methods: Prospective single-blinded observational study of anesthesia providers' preoperative interview of caregivers of consecutive patients younger than age 18 who were scheduled for ambulatory surgery. Results: One hundred one children (30 females) were identified, with a mean age of 6.9 ± 5.0 years; 54 were classified as white, 33 as black, and 14 as other. Total OSA-18 scores ranged from 18 to 97, with a mean of 33.1 ± 14.8. The mean score for adenotonsillectomy patients was higher than that for children who underwent procedures other than adenotonsillectomy. Thirty-one percent of children were screened for OSA, and snoring was the most common symptom recorded (28%). Patients who were screened for OSA were more likely to have snoring (p Tawfik KO, Smith DF, Cheung K, Pringle LM, Stephen MJ, Everett TL, Stierer TL.

    This study investigated the feasibility, safety and efficacy of Coblation endoscopic lingual lightening (CELL) surgery for obstructive sleep apnea (OSA). This study was a retrospective case series in a tertiary referral sleep center. Twenty-five adults with moderate to severe OSA and determined to have retropalatal and tongue base obstruction based on Friedman tongue position III and fiberoptic endoscopy underwent CELL in combination with modified uvulopalatopharyngoplasty, known as relocation pharyngoplasty. CELL involves transoral resection of tongue base muscle tissue and lingual tonsil using Coblation under endoscopic guidance. The mean operation time for CELL was 42.6 ± 13.7 min. Total blood loss for CELL plus relocation pharyngoplasty was <50 ml in all patients. Mean postoperative pain score (sum of total pain scores/sum of total hospitalization day, visual analog scale, 0-10) was 2.6 ± 0.6. Postoperative bleeding and taste disturbance extending beyond 3 months occurred in one patient (4 %) individually. No patients reported tongue weakness or speech dysfunction. Epworth sleepiness scale improved from 9.6 ± 4.9 to 7.5 ± 4.3 (p = 0.023). Apnea-hypopnea index decreased from 45.7 ± 21.7 to 12.8 ± 8.2 events/hour (p < 0.001) 6 months after surgery. The overall response rate was 80 %. CELL is feasible, safe and effective in treating tongue base obstruction in OSA patients who underwent simultaneous relocation pharyngoplasty.

  8. Ventricular dysfunction in children with obstructive sleep apnea: radionuclide assessment

    International Nuclear Information System (INIS)

    Ventricular function was evaluated using radionuclide ventriculography in 27 children with oropharyngeal obstruction and clinical features of obstructive sleep apnea. Their mean age was 3.5 years (9 months to 7.5 years). Conventional clinical assessment did not detect cardiac involvement in 25 of 27 children; however, reduced right ventricular ejection fraction (less than 35%) was found in 10 (37%) patients (mean: 19.5 +/- 2.3% SE, range: 8-28%). In 18 patients wall motion abnormality was detected. In 11 children in whom radionuclide ventriculography was performed before and after adenotonsillectomy, right ventricular ejection fraction rose from 24.4 +/- 3.6% to 46.7 +/- 3.4% (P less than 0.005), and in all cases wall motion showed a definite improvement. In five children, left ventricular ejection fraction rose greater than 10% after removal of oropharyngeal obstruction. It is concluded that right ventricular function may be compromised in children with obstructive sleep apnea secondary to adenotonsillar hypertrophy, even before clinical signs of cardiac involvement are present

    Full Text Available Taryn Heck,1 Monica Zolezzi21Pharmacy Department, University of Alberta Hospital, Alberta Health Services, Edmonton, AB, Canada; 2Clinical Pharmacy and Practice, College of Pharmacy, Qatar University, Doha, QatarAbstract: Psychiatric disorders and obstructive sleep apnea (OSA are often comorbid. However, there is limited information on the impact of psychotropic medications on OSA symptoms, on how to manage psychiatric pharmacotherapy in patients presenting with OSA, or on the effectiveness and challenges of OSA treatments in patients with comorbid mental illness. As such, the objective of this article is to provide an overview of some epidemiological aspects of OSA and treatment considerations in the management of OSA in individuals with comorbid psychiatric disorders. Predefined keywords were used to search for relevant literature in electronic databases. Data show that OSA is particularly prevalent in patients with psychiatric disorders. The medical care that patients with these comorbidities require can be challenging, as some of the psychiatric medications used by these patients may exacerbate OSA symptoms. As such, continuous positive airway pressure continues to be the first-line treatment, even in patients with psychiatric comorbidity. However, more controlled studies are required, particularly to determine continuous positive airway pressure compliance in patients with mental illness, the impact of treating OSA on psychiatric symptoms, and the impact of the use of psychotropic medications on OSA symptoms.Keywords: obstructive sleep apnea, psychiatric disorders, comorbidity, psychotropic medications

We hypothesized that socioeconomic factors and a language barrier would impact adherence with continuous positive airway pressure (CPAP among Hispanics with obstructive sleep apnea (OSA. Methods. Patients with OSA who were prescribed CPAP for at least 1 year and completed a questionnaire evaluating demographic data, socioeconomic status, and CPAP knowledge and adherence participated in the study. Results. Seventy-nine patients (26 males; 53±11 yrs; body mass index (BMI=45±9 kg/m2 with apnea-hypopnea index (AHI 33±30 events/hr completed the study. Included were 25 Hispanics, 39 African Americans, and 15 Caucasians, with no difference in age, AHI, CPAP use, or BMI between the groups. While there was a difference in educational level (P=0.006, income level (P<0.001, and employment status (P=0.03 between the groups, these did not influence CPAP adherence. Instead, overall improvement in quality of life and health status and perceived benefit from CPAP influenced adherence, both for the group as a whole (P=0.03, P=0.004, and P=0.001, resp., as well as in Hispanics (P=0.02, P=0.02, P=0.03, resp.. Conclusion. In Hispanic patients with OSA, perceived benefit with therapy, rather than socioeconomic status or a language barrier, appears to be the most important factor in determining CPAP adherence.

    Hypersomnia is one of the most consulted symptoms among patients evaluated at sleep disorder centers and it is frequently related to obstructive sleep apnea syndrome (OSAS). Our hypothesis is that Epworth sleepiness scale (ESS) is the parameter with the greatest predictive value in the OSAS diagnosis. We compared patients with OSAS diagnosis to a control group. In both groups we compared ESS with body mass index (BMI), neck circumference (NC), waist perimeter (WP). Anthropometric index (BMI, NC and WC), were similar in both groups (p < 0.10). When we analyzed ESS, a score greater than 10 was observed in the OSAS group, with a significant difference between groups (p < 0.001). Epworth sleepiness scale yielded 60% of sensibility, 82% of specificity and a positive predictive value of 85%. The negative predictive value was 52%. Confidence index was 70%. The relationship between OSAS and ESS scale was significant (Pearson Chi-Square value 7.5). Odds Ratio for apneas was 15 and its confidence interval was lower than 1.5 and upper than 141. We conclude that with ESS score exceeding 10 points OSAS should be suspected. PMID:11436699

    Few studies have investigated factors associated with continuous positive airway pressure (CPAP) treatment for sleep apnea from the patients' and their partners' perspective. This qualitative research study explored patients' and partners' experiences of CPAP and facilitators and barriers to CPAP use, and elicited suggestions for a first-time CPAP user program. Data from 27 participants were collected via four sleep apnea patient and four partner focus groups. Qualitative content analysis identified five themes: knowledge of sleep apnea, effects of sleep apnea, effects of CPAP, barriers and facilitators of CPAP, and ideas for a new user support program. Patients and partners emphasized the importance of partner involvement in the early CPAP treatment period. These data suggest consideration of a couple-oriented approach to improving CPAP adherence.

    Abstract Hypertension, blood pressure variation, and resistant hypertension have close relations to sleep apnea, which lead to target organ damage, including the kidney. The complex relationships between sleep apnea and blood pressure cause their interactions with chronic kidney disease ambiguous. The aim of the study was to elucidate the separate and joint effects of sleep apnea, hypertension, and resistant hypertension on chronic kidney disease. A cross-sectional study was done to see the associations of sleep apnea, hypertension, and resistant hypertension with chronic kidney disease in 998 subjects underwent overnight polysomnography without device-therapy or surgery for their sleep-disordered breathing. Multivariate logistic regression was used to analyze the severity of SA, hypertension stage, resistant hypertension, and their joint effects on CKD. The multivariable relative odds (95% CI) of chronic kidney disease for the aged (age ≥65 years), severe sleep apnea, stage III hypertension, and resistant hypertension were 3.96 (2.57–6.09) (P < 0.001), 2.28 (1.13–4.58) (P < 0.05), 3.55 (1.70–7.42) (P < 0.001), and 9.42 (4.22–21.02) (P < 0.001), respectively. In subgroups analysis, the multivariable relative odds ratio of chronic kidney disease was highest in patients with both resistant hypertension and severe sleep apnea [13.42 (4.74–38.03)] (P < 0.001). Severe sleep apnea, stage III hypertension, and resistant hypertension are independent risk factors for chronic kidney disease. Patients with both severe sleep apnea and resistant hypertension have the highest risks. PMID:27281098

  7. Chronic obstructive pulmonary disease and obstructive sleep apnea: overlaps in pathophysiology, systemic inflammation, and cardiovascular disease.

    LENUS (Irish Health Repository)

    McNicholas, Walter T

    2012-02-01

    Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea syndrome represent two of the most prevalent chronic respiratory disorders in clinical practice, and cardiovascular diseases represent a major comorbidity in each disorder. The two disorders coexist (overlap syndrome) in approximately 1% of adults but asymptomatic lower airway obstruction together with sleep-disordered breathing is more prevalent. Although obstructive sleep apnea syndrome has similar prevalence in COPD as the general population, and vice versa, factors such as body mass index and smoking influence relationships. Nocturnal oxygen desaturation develops in COPD, independent of apnea\\/hypopnea, and is more severe in the overlap syndrome, thus predisposing to pulmonary hypertension. Furthermore, upper airway flow limitation contributes to nocturnal desaturation in COPD without apnea\\/hypopnea. Evidence of systemic inflammation in COPD and sleep apnea, involving C-reactive protein and IL-6, in addition to nuclear factor-kappaB-dependent pathways involving tumor necrosis factor-alpha and IL-8, provides insight into potential basic interactions between both disorders. Furthermore, oxidative stress develops in each disorder, in addition to activation and\\/or dysfunction of circulating leukocytes. These findings are clinically relevant because systemic inflammation may contribute to the pathogenesis of cardiovascular diseases and the cell\\/molecular pathways involved are similar to those identified in COPD and sleep apnea. However, the pathophysiological and clinical significance of systemic inflammation in COPD and sleep apnea is not proven, and thus, studies of patients with the overlap syndrome should provide insight into the mechanisms of systemic inflammation in COPD and sleep apnea, in addition to potential relationships with cardiovascular disease.

    Full Text Available Background: Brain death is the absence of all cortical functions, including the brainstem. The apnea test (AT is a necessary requisite to complete this diagnosis. Anecdotal reports describing hypotension and acidosis due to apnea test have been reported. However, there are few studies that evaluate complications or difficulties related to this procedure. Objective: To analyze medical problems associated with the apnea test. Methods and Patients: We analyzed clinical features, potential risk conditions, and problems in 129 brain dead patients during the apnea test. The diagnosis of brain death was made according to the American Academy of Neurology recommendations. Results: Clinical problems during the apnea test were detected in more than two thirds of patients, including: arterial hypotension (12%, acidosis (68%, and hypoxemia (23%. Four patients developed major complications, including: pneumothorax, cardiac arrest, bradycardia, atrial fibrillation and myocardial infarction. Conclusion: The apnea test is not an innocuous procedure. Complications during the AT are more common than reported and limit organ procurement for transplantation. Guidelines for performing the AT should be followed in order to avoid clinical complications.

    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. There seems to be a synergistic effect between smoking and OSAS, both causing an increase in cardiovascular morbidity. Future studies are needed in order to establish the strength of this association. We aim to review the literature regarding the consequences of smoking on sleep architecture and SDB, adding emphasis on OSAS clinical implications and treatment.

    Full Text Available Obstructive sleep apnea (OSA syndrome is a prevalent condition characterized by repeated episodes of obstruction of the upper airway, leading to intermittent hypoxemia and important endothelial and anatomical dysfunctions that cause cardiovascular and cerebrovascular disease. The finding of the relationship between OSA and hypertension, especially resistant hypertension (RHT, has increased the interest in therapeutic strategies that affect renal sympathetic activity in these patients. The observational studies published until now demonstrated that renal denervation therapy can reduce the severity of OSA syndrome. Renal sympathetic denervation (RDN could be a future therapeutic possibility for conditions other than RHT, such as atrial fibrillation, heart failure, obesity, and OSA syndrome, where renal sympathetic system plays an important physiological role. The aim of this review was to elucidate the implications of renal sympathetic activity in OSA syndrome.

    Central sleep apnea (CSA) in patients with heart failure (HF) occurs frequently and shows a serious influence on prognosis in this population. The key elements in the pathophysiology of CSA are respiratory instability with chronic hyperventilation, changes of arterial carbon dioxide pressure (pCO2) and elongated circulation time. The main manifestation of CSA in patients with HF is Cheyne-Stokes Respiration (CSR). The initial treatment is the optimization of HF therapy. However, many other options of the therapeutic management have been studied, particularly those based on positive airway pressure methods. In patients with heart failure we often can observe the overlap of CSA and CSR; we will discuss the differences between these forms of breathing disorders during sleep. We will also discuss when CSA and CSR occur independently of each other and the importance of CSR occurring during the daytime in context of CSA during the nighttime.

    Full Text Available OBJECTIVE: To evaluate the impact of obstructive sleep apnea (OSA on cognition. METHOD: We compared the performance of 17 patients with polysomnographic diagnosis of OSA in brief cognitive tests to that of 20 healthy controls, matched for age and education. The testing battery included the Mini-Mental State Examination (MMSE, Brief Cognitive Screening Battery (BCSB, Digit-Symbol (DS and Phonemic Verbal Fluency (FAS. Anthropometric measures and scores from the Epworth Sleepiness Scale were also recorded. RESULTS: OSA patients performed significantly worse than controls in the MMSE, in memory items from the BCSB, in DS and also in FAS. OSA patients also exhibited higher body mass index, increased neck circumference and higher scores in Epworth Sleepiness Scale than controls. CONCLUSION: OSA significantly impairs cognitive performance, especially within the domains of attention, memory and executive functioning. These deficits may be detected by brief and easy-to-administer cognitive tests.

The main manifestation of CSA in patients with HF is Cheyne-Stokes Respiration (CSR). The initial treatment is the optimization of HF therapy. However, many other options of the therapeutic management have been studied, particularly those based on positive airway pressure methods. In patients with heart failure we often can observe the overlap of CSA and CSR; we will discuss the differences between these forms of breathing disorders during sleep. We will also discuss when CSA and CSR occur independently of each other and the importance of CSR occurring during the daytime in context of CSA during the nighttime. PMID:26961739

    Human butyrylcholinesterase (EC 3.1.1.8) (BChE) is present in serum mainly as "usual UU" form, but it has also been found in variant forms known as "atypical" BChE. The most important predictive value of BChE phenotype is for anesthetist to prevent prolonged apnea. BChE has an important role in the hydrolysis of neuromuscular relaxant succinylcholine (suxamethonium, scoline) used during anesthesia. In order to detect atypical variants of BChE and give these findings to the anesthetists-surgeons before an operation to avoid the prolonged apnea, we phenotyped 542 sera of children before tonsillectomies. Total BChE activity was measured using butyrylthiocholine as substrate and dibucaine, fluoride, urea and dimethylcarbamate Ro 02-0683 were used as inhibitors. The frequencies of phenotypes in 542 children were: UU, UA, US, SS, AS and AA--92.25%, 7.01%, 0.18%, 0.18%, 0.18%, 0.18% respectively. Once established phenotype of BChE does not change during the lifetime. Therefore the carriers of atypical phenotype of BChE received a "Warning card", which is a permanent warning for succinylcholine application, as well as a sign to the members of the families to test their own phenotype of BChE. In our study three "Warning cards" were given: two to the carriers of atypical phenotype and third to a child presented as SS phenotype with low total activity of BChE. The present study is the first clinical evaluation of this genetic abnormality in the Republic of Croatia. PMID:12674844

Recent studies have shown that it is associated with atherosclerosis and left ventricular dysfunction markers. The aim of this study was to assess the cardiovascular effects of OSA depending on its severity, in patients without clinically diagnosed cardiovascular disease. One hundred thirty newly diagnosed, nondiabetic OSA patients (mean age 49 ± 10 years, without vasoactive treatment were included. They underwent clinical and ambulatory blood pressure measurements, echocardiography, carotid ultrasound examination, and a carotid–femoral pulse wave velocity (PWV measurement. Seventy-five percent of the subjects were hypertensive according to the clinical or ambulatory measurement. More patients with the most severe forms (respiratory disturbance index >37/hour had a nondipper profile (52% vs 34%; P = 0.025 and their left ventricular mass was higher (40 ± 7 vs 36 ± 8 g/m, p = 0.014. This last parameter was independently and inversely associated with mean nocturnal oxygen saturation (P = 0.004. PWV and carotid intima-media thickness did not differ between one OSA severity group to another, but the prevalence of carotid hypertrophy was higher when mean SaO2 was below 93.5% (29.5 vs 16%; P = 0.05. Our study shows that in OSA patients without clinically diagnosed cardiovascular disease, there is a significant left ventricular and arterial effect, which is even more marked when OSA is severe.Keywords: obstructive sleep apnea, hypertension, left ventricular hypertrophy, intima-media thickness, arterial stiffness

    Introduction  Obstructive Sleep Apnea (OSA) is characterized by repeated episodes of upper airway obstruction during sleep. Objective  The objective of this study is to verify the craniofacial characteristics and craniocervical posture of OSA and healthy subjects, determining possible relationships with the apnea/hypopnea index (AHI). Methods  This case-control study evaluated 21 subjects with OSA, who comprised the OSA group (OSAG), and 21 healthy subjects, who constituted the control group (CG). Cephalometry analyzed head posture measurements, craniofacial measurements, and air space. Head posture was also assessed by means of photogrammetry. Results  The groups were homogeneous regarding gender (12 men and 9 women in each group), age (OSAG = 41.86 ± 11.26 years; GC = 41.19 ± 11.20 years), and body mass index (OSAG = 25.65 ± 2.46 kg/m2; CG = 24.72 ± 3.01 kg/m2). We found significant differences between the groups, with lower average pharyngeal space and greater distance between the hyoid bone and the mandibular plane in OSAG, when compared with CG. A positive correlation was found between higher head hyperextension and head anteriorization, with greater severity of OSA as assessed by AHI. Conclusion  OSAG subjects showed changes in craniofacial morphology, with lower average pharyngeal space and greater distance from the hyoid bone to the mandibular plane, as compared with healthy subjects. Moreover, in OSA subjects, the greater the severity of OSA, the greater the head hyperextension and anteriorization. PMID:27413397

    Background This pilot study examined airway characteristics during upper endoscopy to determine who is at high risk for obstructive sleep apnea. Methods Patients undergoing routine upper endoscopy were divided into 2 groups according to the Berlin Questionnaire (high and low risk for sleep disordered breathing). Patients underwent routine upper endoscopy using propofol sedation. The airway was then evaluated for no, partial, or complete collapse at the levels of the palate/uvula/tonsils, the tongue base, the hypopharynx, and the larynx. They were given a score of 0 for no collapse, 1 for partial collapse, and 2 for complete collapse. The score for each of these levels was added to give a total score or severity index. The larynx was also evaluated for lateral pharyngeal collapse (minimal, up to 50%, >50%, or 100%). Results We found that patients with a partial obstruction at the level of the palate/uvula/tonsils, tongue base, hypopharynx, or larynx, or complete obstruction at any level more often had a positive Berlin questionnaire. Patients with a positive Berlin questionnaire were more often of increased weight (mean 197 vs 175 lbs, P=0.19), increased body mass index (31.2 vs 27.42 kg/m2, P=0.11), increased neck circumference (36.7 vs 34.7 cm, P=0.23), and had a higher total airway score (2.61 vs 1.67, P=0.09). Conclusions The results of our pilot study represent preliminary data regarding the use of upper endoscopy as a potential tool to evaluate patients for obstructive sleep apnea.

    @@ Based on available population-based studies, Obstructive Sleep Apnea (OSA) associated with accompanying daytime sleepiness affects 3% to 7% of adult men and 2% to 5% of adult women in the general population. In some population subsets, like obese or older people, this prevalence is even higher. The health risk in OSA patients shows a strong association with acute cardiovascular events such as stroke, myocardial infarction and nocturnal sudden death.1,2 And with chronic conditions such as coronary artery disease, heart failure, and especially, systemic hypertension.3,4 In this review, prevalence and incidence of hypertension in OSA patients and the relationships between OSA and its confounders are considered, and of course, these confounders are also generally taken as risk factors for hypertension.

    Negative upper airway pressure is thought to play a key role in the pathophysiology of obstructive sleep apnea. Because nasal resistance contributes to the increase of the transpharyngeal pressure gradient, we evaluated the effects of nasal surgery on sleep-related breathing abnormalities in 20 adults with obstructive sleep apnea. Polysomnographic studies were done before (baseline), and 2 to 3 mo after surgery (septoplasty, turbinectomy, and/or polypectomy). Nasal resistances were measured at these visits in 14 patients. Cephalometric measurements were obtained before surgery. Cephalometric abnormalities consisted in an increase in the distance from the mandibular plane to the hyoid bone (MP-H), a decrease in the space between the base of the tongue and the posterior soft tissues (PAS), a retroposition of the mandibule, and an increase in the length of the soft palate. Body weight did not change between the two studies. Nasal resistance decreased significantly after nasal surgery. The composition of the total sleep time spent in the rapid eye movement stage increased from 11.5 +/- 1.3% (mean +/- SEM) to 14 +/- 1.2% after surgery. For the group as the whole, there was no difference between baseline and postsurgical values in the frequency of respiratory disturbances (39.8 +/- 6.1, 36.8 +/- 5.9 n/h), the total apnea time (17.8 +/- 4.2, 15.4 +/- 2.8), the distribution of the apnea time within the different apnea types (obstructive and nonobstructive), and the severity of the nocturnal desaturations. Interestingly, apnea and apnea plus hypopnea indices returned to normal values (< 5 and 10, respectively) in four subjects with normal posterior soft tissues and mandibular plane to the hyoid bone distances.(ABSTRACT TRUNCATED AT 250 WORDS)

    Colloidal cysts are congenital intracranial benign lesions of the anterior superior portion of the third ventricle. They represent between the 0,2 and 2 % of all the intracranial tumours and represent the 15 or 20 % of all the intraventricular masses. They become symptomatic during the adolescence or early adulthood and start normally with migraine or symptoms of intracranial hypertension causing obstructive hydrocephaly. We present the case of a teenager of 18 years of age with history of migraine after two years and the symptoms worsened in intensity and frequency including vomiting and bilateral paresthesia; the diagnosis was obstructive hydrocephaly with colloidal cyst of the third ventricle. An appropriate practice was adopted due to the uncertain diagnosis in order to avoid neurological damage and death. We discussed the main characteristics of the colloidal cyst, its clinical presentation and radiological characteristics and we performed.

    Introducción: la obesidad afecta a la función respiratoria e incrementa el riesgo de síndrome de apneas-hipopneas del sueño (SAHS). Objetivo: evaluar el efecto de la cirugía bariátrica, en mujeres con obesidad mórbida, sobre la función respiratoria y sobre el índice de apneas-hipopneas (IAH) tras dos años de seguimiento. Métodos: se incluyeron 15 mujeres (índice de masa corporal [IMC] medio 50,52 ± 12,71 kg.m-2, edad media 40,13 ± 10,06 años). Los enfermos fueron analizados en dos fases: previo a la cirugía bariátrica y tras dos años de la misma. En cada visita se valoraron las medidas antropométricas y se realizaron pruebas de función respiratoria consistentes en espirometría, pletismografía, medida de la presión inspiratoria máxima y del índice de tensión-tiempo de los músculos inspiratorios, así como análisis de gases arteriales. Por último, también se efectuó una poligrafía cardiorrespiratoria durante el sueño. Resultados: tras la cirugía bariátrica el IMC disminuyó en 44,07 kg.m-2 (IC 95% 38,32 – 49,81). De igual forma, se observaron incrementos significativos en el volumen espiratorio forzado al primer segundo (FEV1) (p < 0,01), la capacidad vital forzada (FVC) (p < 0,01), el volumen de reserva espiratorio (ERV) (p = 0,040), la capacidad funcional residual (FRC) (p = 0,009) y la resistencia de las vías aéreas (Raw) (p = 0,018). Por otra parte, el IAH (p = 0,001) y el índice de desaturación de oxígeno (p = 0,001) disminuyeron tras la cirugía. Se observó una correlación significativa entre el grado de pérdida de peso y el incremento del ERV (0,774, p = 0,024). Conclusiones: tras dos años desde la cirugía bariátrica se siguen observando mejorías significativas en la función respiratoria y en la gravedad del SAHS. La mejoría del ERV estaría en relación directa con los niveles de peso perdido.

    Prior research has shown that individuals with obstructive lung disease are at risk for sleep fragmentation and poor sleep quality. We postulated that patients with chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (known as overlap syndrome) who have more severe lung disease, as measured by lung hyperinflation (inspiratory capacity/total lung capacity), would have greater sleep disturbances independent of traditional measures of sleep apnea. We performed a retrospective chart review of consecutive patients evaluated and treated in an academic pulmonary clinic for overlap syndrome. Pulmonary function tests and polysomnogram data were collected. Thirty patients with overlap syndrome were included in the analysis. We found significant univariable associations between sleep efficiency and apnea/hypopnea index (beta = -0.285, p = 0.01) and between sleep efficiency and lung hyperinflation (beta = 0.654, p = 0.03). Using multivariable linear regression, the relationship between sleep efficiency and lung hyperinflation remained significant (beta = 1.13, p = 0.02) after adjusting for age, sex, body mass index, apnea/hypopnea index, FEV(1)% predicted, oxygen saturation nadir, medications, and cardiac disease. We conclude that increased severity of hyperinflation is associated with worse sleep efficiency, independent of apnea and nocturnal hypoxemia. The mechanisms underlying this observation are uncertain. We speculate that therapies aimed at reducing lung hyperinflation may improve sleep quality in patients with overlap syndrome.

    Apnea is a very common problem for premature infants: apnea of prematurity (AOP) occurs in >50% of babies whose birth weight is less than 1500 g, and AOP is found in almost all babies who are fail to detect apnea, and also give many false alarms. We have created a new algorithm for detection of apnea. Respiration is monitored by continuous measurement of chest impedance (CI). However, the pulsing of the heart also causes fluctuations in CI. We developed a new adaptive filtering system to remove heart activity from CI, thereby giving much more reliable measurements of respiration. The new approach is to rescale the impedance measurement to heartbeat-time, sampling 30 times per interbeat interval. We take the Fourier transform of the rescaled signal, bandstop filter at 1 per beat to remove fluctuations due to heartbeats, and then take the inverse transform. The filtered signal retains all properties except the impedance changes due to cardiac filling and emptying. We convert the variance of CI into an estimated likelihood of apnea.

The mean platelet volume (MPV is a predictor of cardiovascular thromboembolic events. The aim of the present study is to investigate the association between the MPV and disease severity in patients with obstructive sleep apnea syndrome. METHODS: We prospectively included 194 obstructive sleep apnea syndrome patients without cardiovascular disease (mean age 56.5±12.5 years who were undergoing sleep tests. An overnight full laboratory polisomnography examination was conducted on each patient. The patients were divided into 3 groups according to the apnea-hypopnea index (AHI: (1 AHIlow group: 5≤AHI30. RESULTS: The highest MPV values were found in the AHIhigh group compared with other groups (p<0.05 for all. Multiple linear regression analysis indicated that the MPV was associated with the AHI (β=0.500, p<0.001 and the high sensitivity C-reactive protein (hs-CRP level (β=0.194, p=0.010. CONCLUSION: The MPV is independently associated with both disease severity and inflammation in patients with obstructive sleep apnea syndrome.

    Current treatment options are successful in 40% to 60% of children with persistent obstructive sleep apnea after adenotonsillectomy. Residual obstruction assessments are largely subjective and do not clearly define multilevel obstruction. We endeavor to use computational fluid dynamics to perform virtual surgery and assess airflow changes in patients with Down syndrome and persistent obstructive sleep apnea. Three-dimensional airway models were reconstructed from respiratory-gated computed tomography and magnetic resonance imaging. Virtual surgeries were performed on 10 patients, mirroring actual surgeries. They demonstrated how surgical changes affect airflow resistance. Airflow and upper airway resistance was calculated from computational fluid dynamics. Virtual and actual surgery outcomes were compared with obstructive apnea-hypopnea index values. Actual surgery successfully treated 6 of 10 patients (postoperative obstructive apnea-hypopnea index <5). In 8 of 10 subjects, both apnea-hypopnea index and the calculated upper airway resistance after virtual surgery decreased as compared with baseline values. This is a feasibility and proof-of-concept study. Further studies are needed before using these techniques in surgical planning. PMID:27048669

    Full Text Available Obstructive sleep apnea is recognized as having high prevalence and causing remarkable cardiovascular risk. Coronary artery disease has been associated with obstructive sleep apnea in many reports. The pathophysiology of coronary artery disease in obstructive sleep apnea patients probably includes the activation of multiple mechanisms, as the sympathetic activity, endothelial dysfunction, atherosclerosis, and systemic hypertension. Moreover, chronic intermittent hypoxia and oxidative stress have an important role in the pathogenesis of coronary disease and are also fundamental to the development of atherosclerosis and other comorbidities present in coronary artery diseases such as lipid metabolic disorders. Interestingly, the prognosis of patients with coronary artery disease has been associated with obstructive sleep apnea and the severity of sleep disordered breathing may have a direct relationship with the morbidity and mortality of patients with coronary diseases. Nevertheless, treatment with CPAP may have important effects, and recent reports have described the benefits of obstructive sleep apnea treatment on the recurrence of acute heart ischaemic events in patients with coronary artery disease.

    Full Text Available A diagnostic system for sleep apnea based on oxygen saturation and RR intervals obtained from the EKG (electrocardiogram is proposed with the goal to detect and quantify minute long segments of sleep with breathing pauses. We measured the discriminative capacity of combinations of features obtained from RR series and oximetry to evaluate improvements of the performance compared to oximetry-based features alone. Time and frequency domain variables derived from oxygen saturation (SpO2 as well as linear and non-linear variables describing the RR series have been explored in recordings from 70 patients with suspected sleep apnea. We applied forward feature selection in order to select a minimal set of variables that are able to locate patterns indicating respiratory pauses. Linear discriminant analysis (LDA was used to classify the presence of apnea during specific segments. The system will finally provide a global score indicating the presence of clinically significant apnea integrating the segment based apnea detection. LDA results in an accuracy of 87%; sensitivity of 76% and specificity of 91% (AUC = 0.90 with a global classification of 97% when only oxygen saturation is used. In case of additionally including features from the RR series; the system performance improves to an accuracy of 87%; sensitivity of 73% and specificity of 92% (AUC = 0.92, with a global classification rate of 100%.

    Full Text Available Background: Dental practitioners have a key role in the quality of life and prevention of occupational accidents of workers with Obstructive Sleep Apnea Syndrome (OSAS. Aim: The aim of this study was to review the impact of OSAS, the Continuous Positive Airway Pressure (CPAP therapy, and the evidence regarding the use of oral appliances (OA on the health and safety of workers. Materials and Methods: Searches were conducted in MEDLINE (PubMed, Lilacs and Sci ELO. Articles published from January 1980 to June 2014 were included. Results: The research retrieved 2188 articles and 99 met the inclusion criteria. An increase in occupational accidents due to reduced vigilance and attention in snorers and patients with OSAS was observed. Such involvements were related to excessive daytime sleepiness and neurocognitive function impairments. The use of OA are less effective when compared with CPAP, but the results related to excessive sleepiness and cognitive performance showed improvements similar to CPAP. Treatments with OA showed greater patient compliance than the CPAP therapy. Conclusion: OSAS is a prevalent disorder among workers, leads to increased risk of occupational accidents, and has a significant impact on the economy. The CPAP therapy reduces the risk of occupational accidents. The OA can improve the work performance; but there is no scientific evidence associating its use with occupational accidents reduction. Future research should focus on determining the cost-effectiveness of OA as well as its influence and efficacy in preventing occupational accidents.

    Full Text Available Introduction: Obstructive sleep apnea (OSA is considered to be a potentially life threatening disorder, which is characterized by repeated collapse of the upper airway during sleep with cessation of breathing. The cephalometric method despite being a static, two-dimensional evaluation of dynamic three-dimensional structures of the head and neck is useful in diagnosing patients with OSA, as they have shown that significant differences exist between asymptomatic controls and patients with OSA. Aims and Objectives: This study is designed to compare and validate the craniofacial morphology in patients with OSA using lateral cephalometry in both upright and supine position. Materials and Methods: Sixty subjects participated in the study of which 30 were patients with OSA diagnosed by questionnaire and 30 were healthy control group with age range of 25–45 years. Results: The study group demonstrated an increased ANB, mandibular plane angles (GoGn-SN, lower anterior facial height which are statistically significant with a significant P < 0.05. Significant decrease in posterior airway space, increased soft palate length, tongue length, and thickness suggesting reduced airway space in supine posture. Conclusion: Evaluation of craniofacial morphology in OSA patients using lateral cephalometry helps in recognizing the morphological changes induced by altered sleep pattern and for appropriate treatment planning.

  6. Pathophysiologic Mechanisms of Cardiovascular Disease in Obstructive Sleep Apnea Syndrome

    2013-01-01

    Full Text Available Obstructive sleep apnea syndrome (OSAS is a highly prevalent sleep disorder, characterized by repeated disruptions of breathing during sleep. This disease has many potential consequences including excessive daytime sleepiness, neurocognitive deterioration, endocrinologic and metabolic effects, and decreased quality of life. Patients with OSAS experience repetitive episodes of hypoxia and reoxygenation during transient cessation of breathing that provoke systemic effects. Furthermore, there may be increased levels of biomarkers linked to endocrine-metabolic and cardiovascular alterations. Epidemiological studies have identified OSAS as an independent comorbid factor in cardiovascular and cerebrovascular diseases, and physiopathological links may exist with onset and progression of heart failure. In addition, OSAS is associated with other disorders and comorbidities which worsen cardiovascular consequences, such as obesity, diabetes, and metabolic syndrome. Metabolic syndrome is an emerging public health problem that represents a constellation of cardiovascular risk factors. Both OSAS and metabolic syndrome may exert negative synergistic effects on the cardiovascular system through multiple mechanisms (e.g., hypoxemia, sleep disruption, activation of the sympathetic nervous system, and inflammatory activation. It has been found that CPAP therapy for OSAS provides an objective improvement in symptoms and cardiac function, decreases cardiovascular risk, improves insulin sensitivity, and normalises biomarkers. OSAS contributes to the pathogenesis of cardiovascular disease independently and by interaction with comorbidities. The present review focuses on indirect and direct evidence regarding mechanisms implicated in cardiovascular disease among OSAS patients.

    2015-08-01

    Chronic kidney disease (CKD) is associated with high mortality rates and heavy economic and social burdens. Nearly 10% of the United States population suffer from CKD, with fatal outcomes increased by 16-40 times even before reaching end-stage renal disease. The prevalence of obstructive sleep apnea (OSA) is between 3% and 7% in the general population, and has increased dramatically during the last 2 decades along with increased rates of obesity. However, the prevalence of OSA is much greater in patients with CKD. In addition, aggressive dialysis improves OSA. The current literature suggests a bidirectional association between CKD and OSA through a number of potential pathological mechanisms, which increase the possibility of both diseases being possible risk factors for each other. CKD may lead to OSA through a variety of mechanisms, including alterations in chemoreflex responsiveness, pharyngeal narrowing due to fluid overload, and accumulation of uremic toxins. It is also being increasingly recognized that OSA can also accelerate loss of kidney function. Moreover, animals exposed to intermittent hypoxia suffer histopathological renal damage. Potential mechanisms of OSA-associated renal dysfunction include renal hypoxia, hypertension, endothelial dysfunction, activation of the sympathetic nervous system, and increased oxidative stress.

    Objective. To search for articles evaluating the use of tracheostomies (either permanent stomas or tracheostomy tubes) in adult obstructive sleep apnea (OSA) patients and to evaluate the potential for the use of mini tracheostomies as treatment for OSA. Study Design. Systematic review. Methods. Nine databases were searched from inception through July 21, 2015. Results. The overall tracheostomy search yielded 516 articles, of which eighteen studies provided polysomnographic data. No study was identified (empty review) for the use of mini tracheostomies for treating OSA. The mini tracheostomy search yielded ninety-five articles which describe findings for either mini tracheostomy kits (inner cannula diameter of 4 mm) or the performance of mini tracheotomies. Six articles described the use of mini tracheostomies as a temporary procedure to relieve acute upper airway obstruction and none described the use for OSA. For tracheostomy stomal sites, suturing the skin directly to the tracheal rings with defatting can minimize stomal site collapse. The smallest tracheostomy stomal size that can successfully treat OSA has not been described. Conclusion. Mini tracheostomies as small as 4 mm have been successfully used in the short term to relieve upper airway obstruction. Given that polysomnography data are lacking, additional research is needed.

    Purpose of review Perioperative opioid-based pain management of patients suffering from obstructive sleep apnea (OSA) may present challenges because of concerns over severe ventilatory compromise. The interaction between intermittent hypoxia, sleep fragmentation, pain, and opioid responses in OSA, is complex and warrants a special focus of perioperative outcomes research. Recent findings Life-threatening opioid-related respiratory events are rare. Epidemiologic evidence suggests that OSA together with other serious renal and heart disease, is among those conditions predisposing patients for opioid-induced ventilatory impairment (OIVI) in the postoperative period. Both intermittent hypoxia and sleep fragmentation, two distinct components of OSA, enhance pain. Intermittent hypoxia may also potentiate opioid analgesic effects. Activation of major inflammatory pathways may be responsible for the effects of sleep disruption and intermittent hypoxia on pain and opioid analgesia. Recent experimental evidence supports that these, seemingly contrasting, phenotypes of pain-increasing and opioid-enhancing effects of intermittent hypoxia, are not mutually exclusive. Although the effect of intermittent hypoxia on OIVI has not been elucidated, opioids worsen postoperative sleep-disordered breathing in OSA patients. A subset of these patients, characterized by decreased chemoreflex responsiveness and high arousal thresholds, might be at higher risk for OIVI. Summary OSA may complicate opioid-based perioperative management of pain by altering both pain processing and sensitivity to opioid effect. PMID:26545144

    Objective To explore the relationship between hypoxemia and hearing in children with obstructive sleep apnea-hypopnea syndrome. Methods Auditory brainstem responses (ABRs) were recorded in 68 ears and distortion product otoacoustic emissions (DPOAEs) in 60 ears in children with OSAHS and type "A" tympanograms, and in 30 ears in normal children. Results ABR latencies of waves Ⅰ, Ⅲ and Ⅴ, and Ⅰ-Ⅲ, Ⅲ-Ⅴ and Ⅰ-Ⅴ intervals were not statistically different between OSAHS and normal children. Wave Ⅰlatency was delayed in children with OSAHS compared to normal children3 (P<0.05). DPOAE amplitudes in children with mild OSAHS were lower than normal children at 8 kHz (P<0.05). DPOAEs were lower at 6 kHz and 8 kHz in children with moderate/severe OSAHS than normal children (P<0.05). Conclusion Cochlear function was affected when AHI was at or greater than lO/hour. ABR and DPOAE can be used to detect early changes in auditory function in children with OSAHS.

  12. Clinical application ultrafast MRI to the sleep apnea syndrome, 1

    International Nuclear Information System (INIS)

    To evaluate the site of obstruction within upper airway, we observed the Turbo-fast low angle shot (FLASH) imaging, in 10 patients with sleep apnea syndrome (SAS) during wakefulness and sleep. After intravenous injection of Gd-DTPA (0.1 mmol/kg), sequential images of pharyngeal portion were obtained in midline sagittal section. An imaging protocol was 1.13s per image with a 1s delay between images, for a total of 30s. Then sequential images were displayed in a cine on C. R. T.. In eight patients, upper airway obstructions were present during sleep, while narrowings were present in four cases during awake. The sites of obstruction were located at the velopharynx exclusively in three cases, velopharynx plus glosspharynx in three cases, velopharynx plus glosspharynx in one case. Velopharynx plus hypopharynx in one case, respectively. It was concluded that ultrafast MRI had an important role in evaluating the sites of obstruction within upper airway in patients with SAS.

    2010-01-01

    Full Text Available Obstructive sleep apnea syndrome (OSAS is a serious, prevalent condition that has significant morbidity and mortality when untreated. It is strongly associated with obesity and is characterized by changes in the serum levels or secretory patterns of several hormones. Obese patients with OSAS show a reduction of both spontaneous and stimulated growth hormone (GH secretion coupled to reduced insulin-like growth factor-I (IGF-I concentrations and impaired peripheral sensitivity to GH. Hypoxemia and chronic sleep fragmentation could affect the sleep-entrained prolactin (PRL rhythm. A disrupted Hypothalamus-Pituitary-Adrenal (HPA axis activity has been described in OSAS. Some derangement in Thyroid-Stimulating Hormone (TSH secretion has been demonstrated by some authors, whereas a normal thyroid activity has been described by others. Changes of gonadal axis are common in patients with OSAS, who frequently show a hypogonadotropic hypogonadism. Altogether, hormonal abnormalities may be considered as adaptive changes which indicate how a local upper airway dysfunction induces systemic consequences. The understanding of the complex interactions between hormones and OSAS may allow a multi-disciplinary approach to obese patients with this disturbance and lead to an effective management that improves quality of life and prevents associated morbidity or death.

    2016-08-01

    Obstructive sleep apnea (OSA) and more importantly its hallmark, chronic intermittent hypoxia (CIH), are established factors in the pathogenesis and exacerbation of nonalcoholic fatty liver disease (NAFLD). This has been clearly demonstrated in rodent models exposed to intermittent hypoxia, and strong evidence now also exists in both paediatric and adult human populations. OSA and CIH induce insulin-resistance and dyslipidemia which are involved in NAFLD physiopathogenesis. CIH increases the expression of the hypoxia inducible transcription factor HIF1α and that of downstream genes involved in lipogenesis, thereby increasing β-oxidation and consequently exacerbating liver oxidative stress. OSA also disrupts the gut liver axis, increasing intestinal permeability and with a possible role of gut microbiota in the link between OSA and NAFLD. OSA patients should be screened for NAFLD and vice versa those with NAFLD for OSA. To date there is no evidence that treating OSA with continuous positive airway pressure (CPAP) will improve NAFLD but it might at least stabilize and slow its progression. Nevertheless, these multimorbid patients should be efficiently treated for all their metabolic co-morbidities and be encouraged to follow weight stabilization or weight loss programs and physical activity life style interventions.

    1993-10-01

    Our study included 42 patients with obstructive sleep apnea (OSAS) confirmed by polysomnography. In these patients we investigated the clinical manifestations, the results of the laboratory examinations, including polysomnography, ORL observations and tests of pulmonary function, as well as the therapeutic results. Our patients presented a serious set of symptoms which included excessive daytime sleepiness, snoring, obesity, cranio-facial abnormalities, systemic hypertension, cardiac arrhythmias, incapacity to work with precocious retirement, marital conflicts and high incidence of accidents, namely traffic accidents. An adequate treatment, mostly with nasal CPAP (continuous positive airway pressure), induced marked relief of the symptoms; some patients had an advantage in surgical treatment and weight reduction. OSAS is a frequent entity, affecting mostly male adults after the 5th decade. The lack of knowledge about this entity and the common social acceptance of some of its cardinal symptoms induces considerable delays in its diagnosis. The severity of the symptoms, the personal and social risks of excessive daytime sleepiness, the cardio-circulatory effects and the risk of sudden death during sleep justify an early diagnosis in order to prevent the severe evolution of the disease. Its complex physiopathology and multiple etiological factors justify a multidisciplinary approach. PMID:8285115

The clinical relevance of OSA resides in its association with significant morbidities that affect the cardiovascular, neurocognitive, and metabolic systems. The American Academy of Pediatrics recently reiterated its recommendations that children with symptoms and signs suggestive of OSA should be investigated with polysomnography (PSG, and treated accordingly. However, treatment decisions should not only be guided by PSG results, but should also integrate the magnitude of symptoms and the presence or absence of risk factors and signs of OSA morbidity. The first-line therapy in children with adenotonsillar hypertrophy is adenotonsillectomy, although there is increasing evidence that medical therapy, in the form of intranasal steroids or montelukast, may be considered in mild OSA. In this review, we delineate the major concepts regarding the pathophysiology of OSA, its morbidity, diagnosis, and treatment.

    Psoriasis is a chronic inflammatory skin disorder which can impair general routine activities and has been closely related to poor quality of life. Pruritus and scratching are frequently observed, occurring mainly during sleep and precipitating nighttime arousals. Indeed, sleep quality has been shown to be negatively affected in psoriatic patients, in a close relationship with stress exposure and immune response. Although psoriasis is known to impair sleep, leading to insomnia, its association with obstructive sleep apnea (OSA) is controversial. Similarly, OSA is considered a multifactorial inflammatory disease, characterized by intermittent hypoxia, sleep fragmentation and autonomic dysfunction, with important outcomes on the cardiovascular and metabolic systems. Importantly, immunological activities and pro-inflammatory cytokines play a prominent role in both OSA and psoriasis. Currently it is not clear whether OSA is a risk factor for psoriasis development or if psoriasis is a possible predictor of OSA. Thus, our main purpose is to provide an overview of this intriguing relationship and show the current link between psoriasis and OSA in a bidirectional relationship.

    Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder associated with "cardiovascular stress", i.e. cardiovascular risk factors, cardiovascular diseases, and an increased risk of heart failure, stroke, and death. Experimental and clinical studies have characterized potential underlying mechanisms including biventricular dysfunction, atherosclerosis, and arrhythmia. Assessment of these cardiovascular features of OSA requires a spectrum of clinical tools including ECG, echocardiography, exercise testing, and angiography. In contrast to many cardiovascular diseases, the role of blood biomarkers to characterize cardiovascular function and cardiovascular risk in OSA is poorly defined. In the present review we summarize the available data on biomarkers potentially providing information on cardiovascular features in OSA patients without overt cardiovascular disease. The vast majority of studies on biomarkers of cardiovascular stress in OSA evaluated B-type natriuretic peptide (BNP)/N-terminal-B-type natriuretic peptide (NT-proBNP), and cardiac troponins (cTn). Although some studies found significant associations between these cardiac biomarkers and the presence and severity of OSA, data remain conflicting. Also, the detailed pathophysiological mechanisms underlying the link between OSA and hemodynamic cardiac stress (BNP/NT-proBNP) and cardiomyocyte damage (cTn) are poorly understood. Major research efforts are required to establish the clinical role of cardiovascular biomarkers in patients with OSA. PMID:27380998

  19. The consolidation of implicit sequence memory in obstructive sleep apnea.

    Eszter Csabi

    Full Text Available Obstructive Sleep Apnea (OSA Syndrome is a relatively frequent sleep disorder characterized by disrupted sleep patterns. It is a well-established fact that sleep has beneficial effect on memory consolidation by enhancing neural plasticity. Implicit sequence learning is a prominent component of skill learning. However, the formation and consolidation of this fundamental learning mechanism remains poorly understood in OSA. In the present study we examined the consolidation of different aspects of implicit sequence learning in patients with OSA. We used the Alternating Serial Reaction Time task to measure general skill learning and sequence-specific learning. There were two sessions: a learning phase and a testing phase, separated by a 10-hour offline period with sleep. Our data showed differences in offline changes of general skill learning between the OSA and control group. The control group demonstrated offline improvement from evening to morning, while the OSA group did not. In contrast, we did not observe differences between the groups in offline changes in sequence-specific learning. Our findings suggest that disrupted sleep in OSA differently affects neural circuits involved in the consolidation of sequence learning.

    Full Text Available Abstract Background Most lymphomas that involve the tonsil are large B cell lymphomas. Large B-cell lymphoma is a high grade malignancy which progresses rapidly. Tonsillar lymphoma usually presents as either a unilaterally enlarged palatine tonsil or as an ulcerative and fungating lesion over the tonsillar area. Small lymphocytic lymphomas (SLL of the Waldeyer's ring are uncommon. Case presentation We report a 41-year-old male who presented with a ten-year history of snoring. Physical examination revealed smooth bilateral symmetrically enlarged tonsils without abnormal surface change or cervical lymphadenopathy. Palatal redundancy and a narrowed oropharyngeal airway were also noted. The respiratory disturbance index (RDI was 66 per hour, and severe obstruction sleep apnea (OSA was suspected. No B symptoms, sore throat, odynophagia or dysphagia was found. We performed uvulopalatopharyngoplasty (UPPP and pathological examination revealed incidental small B-cell lymphocytic lymphoma (SLL. Conclusion It is uncommon for lymphoma to initially present as OSA. SLL is an indolent malignancy and is not easy to detect in the early stage. We conclude that SLL may be a contributing factor of OSA in the present case.

  1. Ultrafast CT in the diagnosis of sleep apnea during awake tidal breathing

    International Nuclear Information System (INIS)

    With sleep there is normally a decrease in neural output to upper airway muscles. If this decrease is superimposed on a structurally abnormal airway, then sleep apnea may result. Ultrafast CT axially images the upper airway in near real time. The authors compared 11 awake patients with sleep apnea with 24 healthy volunteers during quiet tidal breathing. They found that apneic patients have a small oropharyngeal airway (31.3 mm2 +- 30.2 vs 134.2 mm2 +- 46.6[P=<.0001]). Apneic patients also have significant collapsibility of the nasopharynx (75% +- 18% vs 27% +- 14% [P=<.0001]). Ultrafast CT gives dynamic anatomic definition of the upper airway and provides a means to eulcidate further the pathogenesis of sleep apnea

    The obstructive sleep apnea syndrome (OSAS) is characterized by recurrent obstruction of the upper airway during sleep. In this study, we performed CT scans in 20 adult OSAS patients and 6 control subjects, and measured the airspaces in the nasopharynx, mesopharynx and hypopharynx, using an image analyzer. The airspaces were significantly smaller at all sites of the pharynx in OSAS patients than in the control subjects, but they did not show a positive correlation with the apnea index or the body mass index. In good responders whose apnea indexes improved more than 50% after uvulo-palato-pharyngoplasty (UPPP), the nasopharyngeal and mesopharyngeal airspaces were significantly smaller, and the hypopharyngeal space tended to be larger than in poor responders. Our results suggest that CT scan is a helpful method for analyzing the area of the upper airway, especially in relation to the response to UPPP in adults with OSAS. (author).

    Detection of desaturations on the pulse oximetry signal is of great importance for the diagnosis of sleep apneas. Using the counting of desaturations, an index can be built to help in the diagnosis of severe cases of obstructive sleep apnea-hypopnea syndrome. It is important to have automatic detection methods that allows the screening for this syndrome, reducing the need of the expensive polysomnography based studies. In this paper a novel recognition method based on the empirical mode decomposition of the pulse oximetry signal is proposed. The desaturations produce a very specific wave pattern that is extracted in the modes of the decomposition. Using this information, a detector based on properly selected thresholds and a set of simple rules is built. The oxygen desaturation index constructed from these detections produces a detector for obstructive sleep apnea-hypopnea syndrome with high sensitivity ($0.838$) and specificity ($0.855$) and yields better results than standard desaturation detection approach...

    Full Text Available A sleepy man without sleep apnea at 1609m (5280 feet had disturbed sleep at his home altitude of 3200m (10500 feet. In addition to common disruptors of sleep such as psychophysiologic insomnia, restless leg syndrome, alcohol and excessive caffeine use, central sleep apnea with periodic breathing can be a significant cause of disturbed sleep at altitude. In symptomatic patients living at altitude, a sleep study at their home altitude should be considered to accurately diagnose the presence and magnitude of sleep disordered breathing as sleep studies performed at lower altitudes may miss this diagnosis. Treatments options differ from those to treat obstructive apnea. Supplemental oxygen is considered by many to be first-line therapy.

    Full Text Available Background: Poor sleep quality, insomnia, and restless legs syndrome (RLS and sleep apnea are common in patients with chronic kidney disease (CKD. Clinical correlates of these problems are poorly understood. Aims: This study was to find out the prevalence and correlates of insomnia and subjects with ′high risk for obstructive sleep apnea (OSA′ in adults with chronic kidney disease. Materials and Methods: One hundred and four adults with CKD were included. Their demographic data, details regarding kidney disease and hemodialysis (HD were recorded. Presence of insomnia and its severity was assessed. They were screened for sleep apnea using a validated questionnaire. Results: Average age was 54.17 (΁ 12.96 years. 89.4% had stage 5 nephropathy and 78.8% subjects were on regular HD. Males outnumbered females. Insomnia was reported by 35.5%. Among these, 50% had chronic insomnia. Insomnia subjects had higher prevalence of diabetes (P = 0.01 and depression (P < 0.001. Fifty-one percent subjects were at "high risk for sleep apnea". They had higher prevalence of diabetes (P < 0.001, coronary disease (P = 0.02, insomnia (P = 0.008, and experienced daytime symptoms of insomnia (P < 0.001. However, in the logistic regression, only male gender (odds ratio, OR = 13.59 and daytime symptoms of insomnia (OR = 7.34 were found to be associated with "higher risk for sleep apnea". Conclusion: Insomnia was prevalent in CKD. Nearly half of these patients are at high risk for sleep apnea and a third of them suffer from insomnia. Hence, these patients should be screened for sleep disorders.

    Full Text Available Rates of Sudden Unexplained Infant Death (SUID, bronchiolitis, and central apnea increase in winter in temperate climates. Though associations between these three conditions are suggested, more work is required to establish if there is a causal pathway linking bronchiolitis to SUID through inducing central apnea. Utilizing a large population-based cohort of infants studied over a 20-year period (n = 834,595, from birth years 1989-2009, we analyzed ecological associations between timing of SUID cases, bronchiolitis, and apnea healthcare visits. Data were analyzed between 2013 and 2015. We used a Cox Proportional Hazards model to analyze possible interactions between maternal smoking and maternal asthma with infant bronchiolitis on time to SUID. SUID and bronchiolitis both occurred more frequently in winter. An increase in bronchiolitis clinical visits occurred within a few days prior to apnea visits. We found a temporal relationship between infant bronchiolitis and apnea. In contrast, no peak in SUID cases was seen during peaks of bronchiolitis. Among those without any bronchiolitis visits, maternal smoking was associated with an increased risk of SUID: Hazard Ratio (HR of 2.38 (95% CI: 2.11, 2.67, p-value <0.001. Maternal asthma was associated with an increased risk of SUID among infants with at least one bronchiolitis visit: HR of 2.40 (95% CI: 1.04, 5.54, p-value = 0.04. Consistent trends between bronchiolitis, apnea, and SUID were not established due to small numbers of SUID cases. However, interaction analysis revealed potential differential associations of bronchiolitis and SUID by maternal smoking, maternal asthma status.

    Purpose Treatment-emergent central sleep apnea (TECSA), also called complex apnea, occurs in 5%–15% of sleep apnea patients during positive airway pressure (PAP) therapy, but the clinical predictors are not well understood. The goal of this study was to explore possible predictors in a clinical sleep laboratory cohort, which may highlight those at risk during clinical management. Methods We retrospectively analyzed 728 patients who underwent PAP titration (n=422 split-night; n=306 two-night). Demographics and self-reported medical comorbidities, medications, and behaviors as well as standard physiological parameters from the polysomnography (PSG) data were analyzed. We used regression analysis to assess predictors of binary presence or absence of central apnea index (CAI) ≥5 during split-night PSG (SN-PSG) versus full-night PSG (FN-PSG) titrations. Results CAI ≥5 was present in 24.2% of SN-PSG and 11.4% of FN-PSG patients during titration. Male sex, maximum continuous positive airway pressure, and use of bilevel positive airway pressure were predictors of TECSA, and rapid eye movement dominance was a negative predictor, for both SN-PSG and FN-PSG patients. Self-reported narcotics were a positive predictor of TECSA, and the time spent in stage N2 sleep was a negative predictor only for SN-PSG patients. Self-reported history of stroke and the CAI during the diagnostic recording predicted TECSA only for FN-PSG patients. Conclusion Clinical predictors of treatment-evoked central apnea spanned demographic, medical history, sleep physiology, and titration factors. Improved predictive models may be increasingly important as diagnostic and therapeutic modalities move away from the laboratory setting, even as PSG remains the gold standard for characterizing primary central apnea and TECSA.

    We report a case of X-linked alpha-thalassemia/mental retardation syndrome (ATR-X) with repeated apnea attacks dating from the patient's 12th year. We initially diagnosed them as obstructive apnea due to upper pharyngeal stenosis and laryngomalacia by polysomnography and laryngo-fiberscopy. However, reevaluation after one and a half years revealed that the boy had central and mixed apnea, as well as obstructive apnea. To date, few reports have been published on the causes of apnea attacks in ATR-X patients. We clinicians should therefore consider laryngomalacia as one cause of apnea attacks in ATR-X patients, and choose the appropriate therapy for a pattern of apnea that can change during its clinical course.

    Sleep apnea represents a relative indication for posterior fossa decompression in pediatric patients with Chiari malformation type 1. Duraplasty was associated with improvement of sleep apnea in 100% of patients and dural splitting with improvement in 50% of patients. Duraplasty and dural splitting were associated with a similar reduction in tonsillar herniation on radiographic imaging of 58% (37% excluding tonsillectomy) and 35%, respectively. Longitudinal follow-up studies of patients with either neurologic deficits or severe symptoms will further elucidate the natural history of Chiari malformation type 1 and more appropriately gauge the risk-benefit tradeoff of surgical intervention.

    Obstructive sleep apnea has increased in prevalence in recent years and despite the expansion in sleep medicine services there is a significant unmet burden of disease. This burden presents a challenge to specialists and requires a reappraisal of service delivery, including a move toward lower-cost, simplified methods of diagnosis and treatment, an expansion of the sleep apnea workforce to include suitably trained and equipped primary care physicians and nurses, and the incorporation of chronic disease management principles that link patients to relevant community resources and empower them through new technologies to engage more fully in their own care.

    Conclusions: The aggregate point prevalence of TECSA is about 8% with the estimated range varying from 5% to 20% in patients with untreated OSA. The prevalence tends to be higher for split-night studies compared to full night titration studies. TECSA can occur at any CPAP setting although extremely high CPAP settings could increase the likelihood. Male gender, higher baseline apnea-hypopnea index, and central apnea index at the time of diagnostic study could be associated with the development of TECSA at a subsequent titration study.

    Full Text Available Objective: The purpose of our study was to determine the effect of induced apnea on quality of cardiopulmonary structures during computerized tomographic (CT angiography images in children with congenital heart diseases. Methods: Pediatric patients with congenital heart defects undergoing cardiac CT angiography at our facility in the past 3 years participated in this study. The earlier patients underwent cardiac CT angiography without induced apnea and while, later, apnea was induced in patients, which was followed by electrocardiogram gated cardiac CT angiography. General anesthesia was induced using sleep dose of intravenous propofol. After the initial check CT, on request by the radiologist, apnea was induced by the anesthesiologist by administering 1 mg/kg of intravenous suxamethonium. Soon after apnea ensued, the contrast was injected, and CT angiogram carried out. CT images in the "apnea group" were compared with those in "nonapnea group." After the completion of the procedure, the patients were mask ventilated with 100% oxygen till the spontaneous ventilation was restored. Results: We studied 46 patients, of whom 36 with apnea and yet another 10 without. The quality of the image, visualization of structures such as cardiac wall, outflow tracts, lung field, aortopulmonary shunts, and coronary arteries were analyzed and subjected to statistical analysis (Mann-Whitney U, Fischer′s exact test and Pearson′s Chi-square test. In the induced apnea group, overall image quality was considered excellent in 89% (n = 33 of the studies, while in the "no apnea group," only 30% of studies were excellent. Absent or minimal motion artifacts were seen in a majority of the studies in apnea group (94%. In the nonapnea group, the respiratory and body motion artifacts were severe in 50%, moderate in 30%, and minimal in 20%, but they were significantly lesser in the apnea group. All the studied parameters were statistically significant in the apnea group in

    Full Text Available Introduction: The sympathetic activation is considered to be the main mechanism involved in the development of cardiovascular diseases in obstructive sleep apnea (OSA. The heart rate variability (HRV analysis represents a non-invasive tool allowing the study of the autonomic nervous system. The impairment of HRV parameters in OSA has been documented. However, only a few studies tackled the dynamics of the autonomic nervous system during sleep in patients having OSA. Aims: To analyze the HRV over sleep stages and across sleep periods in order to clarify the impact of OSA on cardiac autonomic modulation. The second objective is to examine the nocturnal HRV of OSA patients to find out which HRV parameter is the best to reflect the symptoms severity. Methods: The study was retrospective. We have included 30 patients undergoing overnight polysomnography. Subjects were categorized into two groups according to apnea–hypopnea index (AHI: mild-to-moderate OSAS group (AHI: 5–30 and severe OSAS group (AHI>30. The HRV measures for participants with low apnea–hypopnea indices were compared to those of patients with high rates of apnea–hypopnea across the sleep period and sleep stages. Results: HRV measures during sleep stages for the group with low rates of apnea–hypopnea have indicated a parasympathetic activation during non-rapid eye movement (NREM sleep. However, no significant difference has been observed in the high AHI group except for the mean of RR intervals (mean RR. The parasympathetic activity tended to increase across the night but without a statistical difference. After control of age and body mass index, the most significant correlation found was for the mean RR (p=0.0001, r=−0.248. Conclusion: OSA affects sympathovagal modulation during sleep, and this impact has been correlated to the severity of the disease. The mean RR seemed to be a better index allowing the sympathovagal balance appreciation during the night in OSA.

    Objective To evaluate the emotional and cognitive status in patients with obstructive sleep apnea syndrome (OSAS),using neuropsychological tests and evoked-related potential (P3).Methods Sixteen patients diagnosed of OSAS were tested by Hamilton rating scale for anxiety (HRSA) and Hamilton rating scale for depression (HRSD). Other three groups, OSAS patient group (n = 21), snoring group (n = 21), and control group (n = 21), were administered polysomnography (PSG), auditory evoked event-related potential (P3), and clinic memory test. The results were analyzed using general linear model (GLM) analysis and Post Hoc test.Results Twelve OSAS patients' scores of HRSA and HRSD were beyond the normal range, 26.42 ± 4.48 and 22.08 ±3.97 respectively. The auditory P3 latency in OSAS group was 363.1 ± 22.9 ms (Fz), 368.57 ± 28.03 ms (Cz), in snoring group 336.57 ± 31.08 ms (Fz), 339.81 ± 31.76 ms (Cz), in control group 340.8 ± 28.7 ms (Fz), 338.29 ± 29.21 ms (Cz).There were significant differences between OSAS group and snoring group, as well as control group (P < 0.05). No significant difference was seen between snoring group and control group. No significant difference was noted in P3 amplitude among three groups. Memory quotient (MQ) reduced in snoring group compared with control group.Conclusions Emotional disturbances are common clinical features in OSAS patients. Abnormal auditory P3 latency indicates the cognitive dysfunction in OSAS patients. Nocturnal hypoxaemia may play an important role on it. Snorers should be monitored because of the tendency to develop cognitive impairment.

Methods:Demographic features and thyroid function tests of 211 patients (59, 28% female with a mean age of 50.9 ± 10.4 years (ranging from 30 to 75 who underwent polysomnography between September 2010 and September 2011 were retrospectively evaluated. Results: Hypothyroidism was detected in 8.3% of the patients with simple snoring and 10.6% of those with OSAS (9.1% in mild OSAS, 20.3% in moderate OSASand 6.3% in severe OSAS. There was no correlation between the severity of OSAS and the rate of hypothyroidism (p=0.620. The incidence of ypothyroidism was 16.9% in women and 6.6% in men and this difference was statistically significant (p=0.024. The polysomnographic findings did not differ between the patients with hypothyroidism and the others (table 5. However, in patients with elevated TSH levels, the rate of desaturation during sleep was high despite a lower AHI (r=0.126, p=0.05. Conclusion: No correlation was seen between the severity of OSAS and the rate of hypothyroidism. Women with OSAS had higher incidence of hypothyroidism. The polysomnographic findings did not differ whether the patient had hypothyroidism or not. The rate of desaturation during sleep was relatively high in patients with elevated TSH levels.

    Full Text Available Objective: The aim of this study was to find an association between the patients with obstructive sleep apnea (OSA and with cervical vertebral anomalies and any further correlation between various anomalies with varying severities of OSA. Materials and Methods: The sample consisted lateral cephalograms of 70 subjects who were diagnosed with OSA and 70 other orthodontic patients who were selected as a control group. The lateral radiographs of both cases and controls were traced and findings were recorded. Results: In total, 21.42% of subjects in the OSA group and 8.57% in the control group were affected with cervical vertebrae anomalies. The statistical analysis reveals that the number of subjects affected with cervical vertebrae anomalies in OSA group is highly significant. A number of cases of fusion were higher than posterior arch deficiency in OSA group and equal in the control group. However, in both the groups, the number of cases with two vertebrae fusion was higher. Further, the higher number of two vertebrae fusion cases in OSA group was found to be statistically significant. The findings of one-way ANOVA for OSA cases reveals the number of cases affected with cervical vertebrae anomalies were statistically highly significant (P < 0.01 in severe cases of OSA. Conclusion: Patients of cervical vertebral anomalies may be at higher risk of developing OSA, and the possibility of the presence of cervical vertebral anomalies may increase with the increase in the severity of OSA. The most common vertebral anomaly was found to be two vertebral fusions.

    Full Text Available Abstract Background Sleep spindles, as detected on scalp electroencephalography (EEG, are considered to be markers of thalamo-cortical network integrity. Since obstructive sleep apnea (OSA is a known cause of brain dysfunction, the aim of this study was to investigate sleep spindle frequency distribution in OSA. Seven non-OSA subjects and 21 patients with OSA (11 mild and 10 moderate were studied. A matching pursuit procedure was used for automatic detection of fast (≥13Hz and slow (Hz spindles obtained from 30min samples of NREM sleep stage 2 taken from initial, middle and final night thirds (sections I, II and III of frontal, central and parietal scalp regions. Results Compared to non-OSA subjects, Moderate OSA patients had higher central and parietal slow spindle percentage (SSP in all night sections studied, and higher frontal SSP in sections II and III. As the night progressed, there was a reduction in central and parietal SSP, while frontal SSP remained high. Frontal slow spindle percentage in night section III predicted OSA with good accuracy, with OSA likelihood increased by 12.1%for every SSP unit increase (OR 1.121, 95% CI 1.013 - 1.239, p=0.027. Conclusions These results are consistent with diffuse, predominantly frontal thalamo-cortical dysfunction during sleep in OSA, as more posterior brain regions appear to maintain some physiological spindle frequency modulation across the night. Displaying changes in an opposite direction to what is expected from the aging process itself, spindle frequency appears to be informative in OSA even with small sample sizes, and to represent a sensitive electrophysiological marker of brain dysfunction in OSA.

    Sleep apnea is often diagnosed using an overnight sleep test called a polysomnography (PSG). Unfortunately, though it is the gold standard of sleep disorder diagnosis, a PSG is time consuming, inconvenient, and expensive. Many researchers have tried to ameliorate this problem by developing other reliable methods, such as using electrocardiography (ECG) as an observed signal source. Respiratory rate interval, ECG-derived respiration, and heart rate variability analysis have been studied recently as a means of detecting apnea events using ECG during normal sleep, but these methods have performance weaknesses. Thus, the aim of this study is to classify the subject into normal- or apnea-subject based on their single-channel ECG measurement in regular sleep. In this proposed study, ECG is decomposed into five levels using wavelet decomposition for the initial processing to determine the detail coefficients (D3-D5) of the signal. Approximately 15 features were extracted from every minute of ECG. Principal component analysis and a support vector machine are used for feature dimension reduction and classification, respectively. According to classification that been done from a data set consisting of thirty-five patients, the proposed minute-to-minute classifier specificity, sensitivity, and subject-based classification accuracy are 95.20%, 92.65%, and 94.3%, respectively. Furthermore, the proposed system can be used as a basis for future development of sleep apnea screening tools. PMID:25226993

    In this experiment, 97 patients with obstructive sleep apnea hypopnea syndrome were divided into three groups (mild, moderate, severe) according to minimum oxygen saturation, and 35 healthy subjects were examined as controls. Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment. The results revealed that as the disease worsened, the mismatch negativity latency was gradually extended, and the amplitude gradually declined in patients with obstructive sleep apnea hypopnea syndrome. Importantly, mismatch negativity latency in severe patients with a persistent time of minimum oxygen saturation 60 seconds. Correlation analysis revealed a negative correlation between minimum oxygen saturation latency and Montreal Cognitive Assessment scores. These findings indicate that intermittent night-time hypoxemia affects mismatch negativity waveforms and Montreal Cognitive Assessment scores. As indicators for detecting the cognitive functional status of obstructive sleep apnea hypopnea syndrome patients, the sensitivity of mismatch negativity is 82.93%, the specificity is 73.33%, the accuracy rate is 81.52%, the positive predictive value is 85.00%, the negative predictive value is 70.21%, the positive likelihood ratio is 3, and the negative likelihood ratio is 0.23. These results indicate that mismatch negativity can be used as an effective tool for diagnosis of cognitive dysfunction in obstructive sleep apnea hypopnea syndrome patients.

    Chiari I malformation is characterized by downward herniation of the cerebellar tonsils through the foramen magnum. Scant data are available on the clinical course, relationship to the extent of herniation on magnetic resonance imaging in Chiari I malformation and the presence of sleep-disordered breathing on polysomnography. Retrospective analysis was performed looking at polysomnographic findings of children diagnosed with Chiari I malformation. Details on how Chiari I malformation was diagnosed, brainstem magnetic resonance imaging findings, and indications for obtaining the polysomnogram in these patients were reviewed. We also reviewed available data on children who had decompression surgery followed by postoperative polysomnography findings. Twenty-two children were identified in our study (11 males, median age 10 years, range 1 to 18). Three had central sleep apnea, five had obstructive sleep apnea, and one had both obstructive and central sleep apnea. Children with sleep-disordered breathing had excessive crowding of the brainstem structures at the foramen magnum and were more likely to have a greater length of herniation compared with those children without sleep-disordered breathing (P = 0.046). Patients with central sleep apneas received surgical decompression, and their conditions were significantly improved on follow-up polysomnography. These data suggest that imaging parameters may correlate with the presence of sleep-disordered breathing in children with Chiari I malformation.

    Full Text Available The aim of the present study was to assess the effects of one-week tongue-task training (TTT on sleep apnea severity in sleep apnea subjects. Ten patients with sleep apnea (seven men, mean [± SD] age 52±8 years; mean apnea-hypopnea [AHI] index 20.9±5.3 events/h underwent 1 h TTT in the authors’ laboratory on seven consecutive days. A complete or limited recording and tongue maximal protruding force were assessed before and after one-week TTT. One-week TTT was associated with a global AHI decrease (pre-TTT: 20.9±5.3 events/h; post-TTT: 16.1±5.1 events/h; P<0.001 and AHI decrease during rapid eye movement sleep (pre-TTT: 32.2±18.4 events/h; post-TTT: 16.7±6.6 events/h; P=0.03, while protruding force remained unchanged. The authors consider these results to be potentially clinically relevant and worthy of further investigation in a large randomized trial.

    Objective: To investigate the relationship between adiponectin genotype polymorphisms and obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: Using the TaqMan polymerase chain reaction(PCR) method, the single nucleotide polymorphisms(SNP)at positions 45 and 276 in the adiponectin gene were determined in Chinese of the Han nationality in the Nanjing district. The OSAHS group consisted of 78 patients, and the control group contained 40 subjects. The association of adiponectin genotype polymorphisms at positions 45 and 276 with obstructive sleep apnea hypopnea syndrome was analyzed. Results: No evidence of a direct association was found between OSAHS and adiponectin genotype SNP at positions 45 and 276(P> 0.05). However, compared with those OSAHS patients having G/T+T/T genotype at position 276, the OSAHS patients with the G/G genotype showed a greater neck circumference(NC), a prolonged duration of the longest apnea event, and elevated levels of blood cholesterol and low-density lipoprotein cholesterol(P < 0.05). Conclusion: No direct association was detected between OSAHS and adiponectin genotype distribution at positions 45 and 276 in Chinese of Han nationality in the Nanjing district. However, OSAHS patients with the adiponectin GIG genotype at position 276 had a larger NC and the longest apnea event compared to those having the adiponectin SNP276 G/T +T/T genotype. This may have an indirect influence on the development of OSAHS.

The mean preoperative LSAT increased from 71% preoperatively to 90% after surgery (P < 0.001. All the patients in our study were successfully treated (AHI < 20 or reduced by 50%. Cephalometric analysis performed after surgery showed a statistically significant correlation between the mean SNA variation and the decrease in the AHI (P = 0.01. The overall mean SNA increase was 6°.Conclusions: Our findings suggest that the improvement observed in the respiratory symptoms, namely the apnea/hypopnea episodes, is correlated with the SNA increase after surgery. This finding may help maxillofacial surgeons to establish selective criteria for the surgical approach to sleep apnea syndrome patients.

  5. Obstructive sleep apnea screening by integrating snore feature classes

    International Nuclear Information System (INIS)

    Obstructive sleep apnea (OSA) is a serious sleep disorder with high community prevalence. More than 80% of OSA suffers remain undiagnosed. Polysomnography (PSG) is the current reference standard used for OSA diagnosis. It is expensive, inconvenient and demands the extensive involvement of a sleep technologist. At present, a low cost, unattended, convenient OSA screening technique is an urgent requirement. Snoring is always almost associated with OSA and is one of the earliest nocturnal symptoms. With the onset of sleep, the upper airway undergoes both functional and structural changes, leading to spatially and temporally distributed sites conducive to snore sound (SS) generation. The goal of this paper is to investigate the possibility of developing a snore based multi-feature class OSA screening tool by integrating snore features that capture functional, structural, and spatio-temporal dependences of SS. In this paper, we focused our attention to the features in voiced parts of a snore, where quasi-repetitive packets of energy are visible. Individual snore feature classes were then optimized using logistic regression for optimum OSA diagnostic performance. Consequently, all feature classes were integrated and optimized to obtain optimum OSA classification sensitivity and specificity. We also augmented snore features with neck circumference, which is a one-time measurement readily available at no extra cost. The performance of the proposed method was evaluated using snore recordings from 86 subjects (51 males and 35 females). Data from each subject consisted of 6–8 h long sound recordings, made concurrently with routine PSG in a clinical sleep laboratory. Clinical diagnosis supported by standard PSG was used as the reference diagnosis to compare our results against. Our proposed techniques resulted in a sensitivity of 93±9% with specificity 93±9% for females and sensitivity of 92±6% with specificity 93±7% for males at an AHI decision threshold of 15 events

  6. Heart rate responses to autonomic challenges in obstructive sleep apnea.

    Paul M Macey

    Full Text Available Obstructive sleep apnea (OSA is accompanied by structural alterations and dysfunction in central autonomic regulatory regions, which may impair dynamic and static cardiovascular regulation, and contribute to other syndrome pathologies. Characterizing cardiovascular responses to autonomic challenges may provide insights into central nervous system impairments, including contributions by sex, since structural alterations are enhanced in OSA females over males. The objective was to assess heart rate responses in OSA versus healthy control subjects to autonomic challenges, and, separately, characterize female and male patterns. We studied 94 subjects, including 37 newly-diagnosed, untreated OSA patients (6 female, age mean ± std: 52.1 ± 8.1 years; 31 male aged 54.3 ± 8.4 years, and 57 healthy control subjects (20 female, 50.5 ± 8.1 years; 37 male, 45.6 ± 9.2 years. We measured instantaneous heart rate with pulse oximetry during cold pressor, hand grip, and Valsalva maneuver challenges. All challenges elicited significant heart rate differences between OSA and control groups during and after challenges (repeated measures ANOVA, p<0.05. In post-hoc analyses, OSA females showed greater impairments than OSA males, which included: for cold pressor, lower initial increase (OSA vs. control: 9.5 vs. 7.3 bpm in females, 7.6 vs. 3.7 bpm in males, OSA delay to initial peak (2.5 s females/0.9 s males, slower mid-challenge rate-of-increase (OSA vs. control: -0.11 vs. 0.09 bpm/s in females, 0.03 vs. 0.06 bpm/s in males; for hand grip, lower initial peak (OSA vs. control: 2.6 vs. 4.6 bpm in females, 5.3 vs. 6.0 bpm in males; for Valsalva maneuver, lower Valsalva ratio (OSA vs. control: 1.14 vs. 1.30 in females, 1.29 vs. 1.34 in males, and OSA delay during phase II (0.68 s females/1.31 s males. Heart rate responses showed lower amplitude, delayed onset, and slower rate changes in OSA patients over healthy controls, and impairments may be more pronounced in

    Abstract Background: To conduct a systematic review to answer the clinical question “What are the effectiveness of mandibular distraction osteogenesis (MDO) and its complications to treat patients with obstructive sleep apnea syndrome (OSAS)?”. Methods: A systematic search including a computer search with specific keywords, reference list search, and manual search were done. Relevant articles on MDO were assessed and selected in 3 rounds for final review based on 5 predefined inclusion criteria and followed by a round of critical appraisal. Different types of distraction and their treatment outcomes of OSAS were recorded with standardized form and analyzed. Results: Twelve articles were included in the final review. A total of 256 patients aged 7 days to 60 years were treated with either external or internal MDO, with a mean follow-up period of 6 to 37 months. The average distraction distance of 12 to 29 mm was achieved with various distraction protocols. The success rate for adult patients was 100%, and cure rates were ranged from 82% to 100%. The definition of success or cure for OSAS in children or infants was not defined. Therefore, there were no clearly reported success or cure rates for children/infants in the included studies. However, all studies reported that these patients showed significant improvement in OSAS, with many of them who avoided tracheostomy or had the tracheostomy decannulated. The complication rates were ranged from 0% to 21.4%, with most being from local wound infections or neurosensory disturbances. Conclusion: This systematic review showed that MDO was effective in resolving OSAS in adults with retrognathic mandible. MDO also showed promising results in infants or children with OSAS. From the results of this systematic review, we recommend to define the criteria of success or cure for OSAS surgery in children and infants. We also recommend setting up randomized controlled trials to compare MDO with traditional maxillomandibular

    Recent studies show an alarming increase in the rate of overweight / obesity among the infant - juvenile population. Obesity in childhood is associated with a significant number of complications, such as sleep apnea syndrome, insulin resistance and type 2 diabetes, hypertension, cardiovascular disease and some cancers. It is estimated that the prevalence of sleep apnea in children is 2-3% in the general population, while in obese adolescents, varies between 13% and 66%, according to various studies. It is associated with impairment of neurocognitive function, behavior, cardiovascular system, metabolic disorders and growth. Sleep apnea is a serious public health problem that increases when children and adolescents are overweight or obese. We hypothesize that aerobic endurance exercise can be an effective treatment for obesity and apnea at the same time. The aim of this study was to determine the influence of physical activity in children and adolescents with overweight / obesity in sleep apnea. An observational, descriptive, prospective, longitudinal study will be carried out in children with sleep apnea and obesity. The universe will be made up of 60 children and adolescents aged between 10 and 18 years, attending the endocrinology service for suffering of obesity in the Hospital Clinico San Cecilio of Granada during the period September 2012-September 2013. The smple will consist of children and adolescents that meet these characteristics and to whom their parents/tutors have authorized through the informed consent. Sleep apnea in children wil be measured by polysomnography and sleep quality questionnaire. There will also be a nutritional assessment by a food frequency questionnaire and an anthropometric assessment. Among the expected results are the lower overweight and obesity in children through the physical activity program. To reduce apnea and to improve sleep quality.

    Sleep disorders disturb the recovery from mental and physical fatigues, one of the functions of the sleep. The majority of those who with the disorders are suffering from Sleep Apnea Syndrome (SAS). Continuous Hypoxia during sleep due to SAS cause Circulatory Disturbances, such as hypertension and ischemic heart disease, and Malfunction of Autonomic Nervous System, and other severe complications, often times bringing the suffers to death. In order to prevent these from happening, it is important to detect the SAS in its early stage by monitoring the daily respirations during sleep, and to provide appropriate treatments at medical institutions. In this paper, the Pneumatic Method to detect the Apnea period during sleep is proposed. Pneumatic method can measure heartbeat and respiration signal. Respiration signal can be considered as noise against heartbeat signal, and the decrease in the respiration signal due to Apnea increases the Average Mutual Information of heartbeat. The result of scaling analysis of the average mutual information is defined as threshold to detect the apnea period. The root mean square error between the lengths of Apnea measured by Strain Gauge using for reference and those measured by using the proposed method was 3.1 seconds. And, error of the number of apnea times judged by doctor and proposal method in OSAS patients was 3.3 times.

    Full Text Available Background: The aim of this study was to evaluate epidemiological relationship between chronic obstructive pulmonary disease and sleep apnea syndrome in a sample of Persian population. Methods: As a part of a population-based cross-sectional study, 3900 randomly selected individuals aged 15 years or older were invited to take part in the survey; 3770 individuals (96.6% agreed to fill out the respiratory and sleep questionnaire. Those subjects suspected to have either chronic obstructive pulmonary disease and/or obstructive sleep apnea underwent spirometry and polysomnography test if indicated. Spirometric measurements were performed on 420 invited responders. Polysomnography measurements were performed on 25 of the responders. Results: Prevalence rates for sleep apnea, chronic obstructive pulmonary disease and current asthma were 4.98%, 5.7% and 3.1%, respectively. Logistic regression showed independent associations between sleep apnea and chronic obstructive pulmonary disease. There was no significant independent association between sleep apnea symptoms and current asthma and wheeze ever. Conclusions: These observations indicated relationship between chronic obstructive pulmonary disease and obstructive sleep apnea. These observations indicated the necessity of further studies to explain the possible common pathogenic mechanisms involved in two disease entities.

    Although sleep apnea syndrome (SAS) is a common sleep disorder, most patients with sleep apnea are undiagnosed and untreated because it is difficult for patients themselves to notice SAS in daily living. Polysomnography (PSG) is a gold standard test for sleep disorder diagnosis, however PSG cannot be performed in many hospitals. This fact motivates us to develop an SAS screening system that can be used easily at home. The autonomic nervous function of a patient changes during apnea. Since changes in the autonomic nervous function affect fluctuation of the R-R interval (RRI) of an electrocardiogram (ECG), called heart rate variability (HRV), SAS can be detected through monitoring HRV. The present work proposes a new HRV-based SAS screening algorithm by utilizing support vector machine (SVM), which is a well-known pattern recognition method. In the proposed algorithm, various HRV features are derived from RRI data in both apnea and normal respiration periods of patients and healthy people, and an apnea/normal respiration (A/N) discriminant model is built from the derived HRV features by SVM. The result of applying the proposed SAS screening algorithm to clinical data demonstrates that it can discriminate patients with sleep apnea and healthy people appropriately. The sensitivity and the specificity of the proposed algorithm were 100% and 86%, respectively. PMID:26738189

    Full Text Available CONTEXT: Intestinal constipation - a common symptom among the general population - is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. OBJECTIVE: To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. METHODS: Twenty-one patients (19 females - 90.4% with a mean age of 47.5 years old (23-72 were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1 and distal (2 portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. RESULTS: The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007, independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06. The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008, either at the proximal portion or at the distal portion of the anal orifice. CONCLUSION: The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides

    In this study, our goal was to identify the key genes that are associated with obstructive sleep apnea (OSA). Thirty-five volunteers underwent full in-lab polysomnography and, according to the sleep apnea hypopnea index (AHI), were classified into control, mild-to-moderate OSA and severe OSA groups. Severe OSA patients were assigned to participate in a continuous positive airway pressure (CPAP) protocol for 6 months. Blood was collected and the expression of 84 genes analyzed using the RT(2) Profiler™ PCR array. Mild-to-moderate OSA patients demonstrated down-regulation of 2 genes associated with induction of apoptosis, while a total of 13 genes were identified in severe OSA patients. After controlling for body mass index, PRPF40A and PLOD3 gene expressions were strongly and independently associated with AHI scores. This research protocol highlights a number of molecular targets that might help the development of novel therapeutic strategies. PMID:23994550

  1. Management of Obstructive Sleep Apnea in an Edentulous Lower Jaw Patient with a Mandibular Advancement Device

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Obstructive sleep apnea (OSA is the most common sleep-related breathing disorder with periodic reduction or cessation of airflow during sleep. It is associated with loud snoring, disrupted sleep, and witnessed apneas. Treatment of OSA varies from simple measures such as oral appliances and nasal continuous positive airway pressure (CPAP to surgical procedures like uvulopalatopharyngoplasty and tracheostomy. Oral appliances are a viable nonsurgical treatment alternative in patients with OSA, of which mandibular advancement devices are most common. Edentulism which contributes to the worsening of OSA reduces the number of available therapeutic strategies and is considered a contraindication to oral appliance therapy. This clinical report describes the treatment of a 63-year-old edentulous OSA patient for whom a mandibular advancement device was designed.

    Full Text Available In some conditions continuous positive airway pressure (CPAP or bilevel positive airway pressure (BIPAP therapy alone fails to provide satisfactory oxygenation. In these situations oxygen (O2 is often being added to CPAP/BIPAP mask or hose. Central sleep apnea and obstructive sleep apnea (OSA are often present along with other chronic conditions, such as chronic obstructive pulmonary disease (COPD, congestive heart failure, pulmonary fibrosis, neuromuscular disorders, chronic narcotic use, or central hypoventilation syndrome. Any of these conditions may lead to the need for supplemental O2 administration during the titration process. Maximization of comfort, by delivering O2 directly via a nasal cannula through the mask, will provide better oxygenation and ultimately treat the patient with lower CPAP/BIPAP pressure.

    Snoring sounds generated by different vibrators of the upper airway may be useful indicators of obstruction sites in patients with obstructive sleep apnea hypopnea syndrome (OSAHS). This study aimed to investigate associations between snoring sounds, obstruction sites, and surgical responses (≥50% reduction in the apnea-hypopnea index [AHI] and Hz; odds ratio [OR], 1.25, 95% confidence interval [CI] 1.05-1.49) and body mass index (OR, 1.48, 95% CI 1.02-2.15) after logistic regression analysis. Tonsil obstruction was significantly, inversely correlated with mean snoring sound intensity (301-850 Hz; OR, 0.84, 95% CI 0.74-0.96). Moreover, baseline tonsil obstruction detected by either DISE or mean snoring sound intensity (301-850 Hz), and AHI could significantly predict the surgical response. Our findings suggest that snoring sound detection may be helpful in determining obstruction sites and predict surgical responses. PMID:27471038

The clinical symptoms are characterized by bulging eyes, ophthalmoplegia, dysarthria, rigospasticity of the lower limbs, marked dystonia and bradykinesia. In our cases, extrapyramidal symptoms were improved by amantadine and L-dopa therapy. CSF homovanilic acid (HVA) was markedly reduced. Muscle biopsy and electromyographic studies revealed neurogenic changes. MRI revealed mild atrophy of frontal lobe and cerebellum, and marked atrophy of brain stem. These findings were consistent with the clinical manifestations. Our case had central type sleep apnea by sleep EEG and polygraphic studies. This is the first report about sleep apnea and MRI of Joseph disease.

  7. Automated detection of sleep apnea from electrocardiogram signals using nonlinear parameters

    International Nuclear Information System (INIS)

    Sleep apnoea is a very common sleep disorder which can cause symptoms such as daytime sleepiness, irritability and poor concentration. To monitor patients with this sleeping disorder we measured the electrical activity of the heart. The resulting electrocardiography (ECG) signals are both non-stationary and nonlinear. Therefore, we used nonlinear parameters such as approximate entropy, fractal dimension, correlation dimension, largest Lyapunov exponent and Hurst exponent to extract physiological information. This information was used to train an artificial neural network (ANN) classifier to categorize ECG signal segments into one of the following groups: apnoea, hypopnoea and normal breathing. ANN classification tests produced an average classification accuracy of 90%; specificity and sensitivity were 100% and 95%, respectively. We have also proposed unique recurrence plots for the normal, hypopnea and apnea classes. Detecting sleep apnea with this level of accuracy can potentially reduce the need of polysomnography (PSG). This brings advantages to patients, because the proposed system is less cumbersome when compared to PSG

    Full Text Available

    A 52-year-old obese woman was admitted to our institution for evaluation of dyspnea and pulmonary hypertension (PH. Polysomnography revealed severe obstructive sleep apnea (OSA with an apnea hypopnea index of 99.8. Treatment with nocturnal continuous positive airway pressure (CPAP resulted in correction of daytime hypoxemia, hypercapnia, and near-normalization of pulmonary artery pressure. To our knowledge, this is the most severe case of OSA-associated PH (approximately70 mmHg reported to date, and it was successfully treated with nocturnal CPAP. This case demonstrates that OSA should be considered and polysomnography performed in all patients with PH, irrespective of severity, and that nocturnal CPAP has therapeutic effects on both OSA and daytime PH.

    The intent of this study is to develop a predictive model to convert an oxygen desaturation index (ODI) to an apnea-hypopnea index (AHI). This model will then be compared to actual AHI to determine its precision. One thousand four hundred and sixty-seven subjects given polysomnograms with concurrent pulse oximetry between April 14, 2010, and February 7, 2012, were divided into model development (n=733) and verification groups (n=734) in order to develop a predictive model of AHI using ODI. Quadratic regression was used for model development. The coefficient of determination (r2) between the actual AHI and the predicted AHI (PredAHI) was 0.80 (r=0.90), which was significant at a psleep apnea.

    Objective To compare the Cone-Beam Computerized Tomography (CBCT) scan measurements between patients with Obstructive Sleep Apnea (OSA) and snorers to develop a prediction model for OSA based on CBCT imaging and the Berlin Questionnaire. Materials and methods 80 subjects (46 OSA patients with Apnea-Hypoapnea Index [AHI]≥ 10 and 34 snorers AHI57 years, male gender, a “high risk” Berlin Questionnaire and narrow upper airway lateral dimension (<17mm) were identified as significant risk factors for OSA. The results of this study indicate that 3-dimensional CBCT airway analysis could be used as a tool to assess the presence and severity of OSA. The presence and severity (as measured by the RDI) of OSA is associated with a narrow lateral dimension of the airway, increasing age, male gender, and the Berlin questionnaire. PMID:20123412

    Full Text Available The effects of sleep disorders on the quality of life (QOL have been documented in the literature. Excessive sleepiness and altered circadian rhythms may negatively affect ability to learn, employment, and interpersonal relations, and directly degrade QOL. The objective of the present study was to evaluate the impact of obstructive sleep apnea syndrome of varying severity on QOL. The study was conducted on 1892 patients aged 18 years or older referred by a physician to the Sleep Institute, São Paulo, with complaints related to apnea (snoring, excessive daytime sleepiness, hyperarousal, and fatigue. They were submitted to overnight polysomnography for the diagnosis of sleep disorders from August 2005 through April 2006. The patients completed the Epworth Sleepiness Scale and QOL SF-36 sleep questionnaires. They were classified as non-physically active and physically active and not-sleepy and sleepy and the results of polysomnography were analyzed on the basis of the apnea hypopnea index (AHI. The apneic subjects showed a reduction in QOL which was proportional to severity. There was a significant decrease in all domains (physical functioning, role physical problems, bodily pain, general health perceptions, vitality, social functioning, emotional problems, general mental health for apneics with AHI >30, who generally were sleepy and did not participate in physical activities (P < 0.05. The present study provides evidence that the impact of sleep disorders on QOL in apneics is not limited to excessive daytime sleepiness and that physical activity can contribute to reducing the symptoms. Thus, exercise should be considered as an adjunct interventional strategy in the management of obstructive sleep apnea syndrome.

    Obstructive sleep apnea (OSA) is a frequent disease mainly affecting obese people and caused by repetitive collapse of the upper airways during sleep. The increased morbidity and mortality of OSA are mainly thought to be the consequence of its adverse effects on cardiovascular (CV) health. In this context, oxidative stress induced by nocturnal intermittent hypoxia has been identified to play a major role. This is suggested by biomarker studies in OSA patients showing excessively generated rea...

    Full Text Available Introduction and Objective. Obstructive sleep apnea (OSA is characterized by at least 5 ten-second-long episodes of apnea or hypopnea, per hour of sleep. This disease may lead to severe, life-threatening complications. Therefore, risk analysis and its influence on disease intensity is crucial for proper implementation of preventive treatments. Objective. To determine the relation between the intensity of OSA expressed in Apnea-Hypopnea Index (AHI, and the anterior-posterior diameter of upper airways at the levels of soft palate and tongue base. Material and Method. Medical records of 41 patients with sleep apnea (AHI>4 diagnosed through polysomnographic examination obstructive were used for the study. The data consisted of: age and gender, polysomnographic examination results (AHI, lateral cephalogram with cephalomertic analysis, together with measurements of the upper and lower pharyngeal depth according to McNamara. Statistical analysis was carried out in accordance with Pearson’s r correlation coefficient test (Statistica 8.0 software package. Results. Analysis of the influence of upper airways diameter on the intensity of OSA showed that the value of upper Airways diameter at the tongue base level had no statistically significant impact on the value of AHI (p=0.795. However, a statistically significant impact of the value of upper airways diameter on the AHI value (p=0.008 at the soft palate level was observed. Patients with OSA have narrowed upper airways diameter. The value of AHI increases with the decrease of upper diameter and is not dependent on a lower diameter value. Patients with a decreased upper airways diameter should be informed about potential breathing disorders during sleep.

    To our knowledge, no studies up to date have investigated the correlation of rapid eye movement (REM) dependent obstructive sleep apnea syndrome (OSAS) and Muller maneuver. The aim of this study is to investigate whether REM-dependent OSAS is predicted by the findings of the Muller maneuver. The study was conducted on 149 patients with witnessed apnea and daytime sleepiness. Muller maneuver was performed to all patients and the obstruction site was determined using a five-point scale. Then, polysomnography of the patient was obtained and the apnea-hypopnea indexes were determined in total sleep time, REM-dependent sleep and non-REM-dependent sleep. The correlations between the Muller maneuver findings and polysomnographic data were analyzed. The ages of the patients included in the study ranged between 25 and 73 years with a mean age of 49.3 ± 10.1 years. Their mean body mass index was 30.8 ± 5.1 kg/m(2) (range 21.9-55.4 kg/m(2)). The patients' mean apnea-hypopnea indexes in total sleep time was 28.1 and ranged between 5.4 and 124.3. REM-dependent OSAS was determined in 49 patients. When the data were analyzed, it was determined that there were no statistically significant correlations between tongue base or lateral pharyngeal band obstruction at the level of hypopharynx and the REM-dependent OSAS. At the level of the soft palate, the obstruction caused by the lateral pharyngeal bands or soft palate and REM dependency did not show any statistically significant correlation (p > 0.05). In conclusion, Muller maneuver does not provide useful data to predict REM dependency of OSAS.

    Full Text Available Background and Objectives: Obstructive sleep apnea (OSA is associated with sleepiness, depression and reduced quality of life. However, it is unclear whether mild OSA has these negative impacts. Using data from the Apnea Positive Pressure Long-term Efficacy Study (APPLES, this study determined whether participants with mild OSA had greater sleepiness, more depressive symptoms and poorer quality of life in comparison to those without OSA. Methods: 239 evaluated for participation in APPLES with a baseline apnea hypopnea index (AHI < 15 /hour were assigned to 1 of 2 groups: No OSA (N=40, AHI < 5 /hour or Mild OSA (N=199, 5 to <15 /hour based on their screening polysomnogram. Scores on their Epworth Sleepiness Scale (ESS, Stanford Sleepiness Scale (SSS, Hamilton Rating Scale for Depression (HAM-D, Profile of Mood States (POMS and Sleep Apnea Quality of Life Index (SAQLI were compared between groups. Results: There were no significant differences between the No OSA and Mild OSA groups on any of the 5 measures: ESS (OSA, 9.8 + 3.5 vs Mild OSA, 10.6 + 4.3, p=0.26, SSS,(2.8 + 0.9 vs. 2.9 + 1.0, p=0.52, HAM-D (4.6 + 3.0 vs. 4.9 + 4.7, p=0.27, POMS (33.5 + 22.3 vs. 28.7 + 22.0, p=0.70, SAQLI (4.5 + 0.8 vs. 4.7 + 0.7, p=0.39. Conclusion: Individuals with mild OSA in this cohort do not have worse sleepiness, mood or quality of life in comparison to those without OSA.

    Recent years have seen a growing interest in the use of portable monitoring devices for the diagnosis of obstructive sleep apnea syndrome. These have the potential to be used in lieu of the more complicated and uncomfortable alternative, polysomnography, which has long been considered to be the gold standard for the diagnosis of this relatively prevalent condition. Following their approval in 2008 by the Center of Medicare and Medicaid Services, the federal agency which administers Medicare and Medicaid in the United States, there has been extensive discussion about the utility and validity of these devices for use in the diagnosis of obstructive sleep apnea syndrome. Although there are various models of portable monitoring devices, the literature contains little information regarding how each device should be used in specific age groups, patients presenting comorbidities, and asymptomatic patients. Additionally, studies about the cost-effectiveness of this diagnostic method are scarce and conflicting. Therefore, this objective of this study was to review what has been learned about portable monitoring devices over time, as well as to examine the recent progress, advantages, limitations, and applications of these devices in the diagnosis of obstructive sleep apnea syndrome in different groups of patients.

    The aim of the present study was to evaluate the relationship between obstructive sleep apnea syndrome (OSAS) severity and the hippocampal sulcus width in a cohort of subjects with OSAS and controls. A total of 149 OSAS patients and 60 nonapneic controls were included in the study. Overnight polysomnograpy was performed in all patients. Hippocampal sulcus width of the patients was measured by a radiologist blinded to the diagnosis of the patients. Other variables noted for each patient were as follows: gender, age, body mass index, apnea hypopnea index, Epworth sleepiness scale, sleep efficacy, mean saturation, lowest O2 saturation, longest apnea duration, neck circumference, waist circumference, hip circumference. A total of 149 OSAS patients were divided into three groups: mild OSAS (n = 54), moderate OSAS (n = 40), severe OSAS (n = 55) groups. The control group consisted of patients with AHI sulcus width was 1.6 ± 0.83 mm in the control group; while 1.9 ± 0.81 mm in mild OSAS, 2.1 ± 0.60 mm in moderate OSAS, and 2.9 ± 0.58 mm in severe OSAS groups (p sulcus width. Our findings demonstrated that severity of OSAS might be associated with various pathologic mechanisms including increased hippocampal sulcus width.

    Full Text Available Abstract Background The forces developed during inspiration play a key role in determining upper airway stability and the occurrence of nocturnal breathing disorders. Phrenic nerve stimulation applied during wakefulness is a unique tool to assess Upper airway dynamic properties and to measure the overall mechanical effects of the inspiratory process on UA stability. Objectives To compare the flow/pressure responses to inspiratory and expiratory twitches between sleep apnea subjects and normal subjects. Methods Inspiratory and expiratory twitches using magnetic nerve stimulation completed in eleven untreated sleep apnea subjects and ten normal subjects. Results In both groups, higher flow and pressure were reached during inspiratory twitches. The two groups showed no differences in expiratory twitch parameters. During inspiration, the pressure at which flow-limitation occurred was more negative in normals than in apneic subjects, but not reaching significance (p = 0.07. The relationship between pharyngeal pressure and flow adequately fitted with a polynomial regression model providing a measurement of upper airway critical pressure during twitch. This pressure significantly decreased in normals from expiratory to inspiratory twitches (-11.1 ± 1.6 and -15.7 ± 1.0 cm H2O respectively, 95% CI 1.6–7.6, p Conclusion Inspiratory-related upper airway dilating forces are impeded in sleep apnea patients.

    This study assessed decision-making and its associations with executive functions and sleep-related factors in patients with obstructive sleep apnea. Thirty patients with untreated obstructive sleep apnea and 20 healthy age- and education-matched controls performed the Iowa Gambling Task, a decision-making task under initial ambiguity, as well as an extensive neuropsychological test battery. Patients, but not controls, also underwent a detailed polysomnographic assessment. Results of group analyses showed that patients performed at the same level of controls on the Iowa Gambling Task. However, the proportion of risky performers was significantly higher in the patient group than in the control group. Decision-making did not correlate with executive functions and subjective ratings of sleepiness, whereas there was a significant positive correlation between advantageous performance on the Iowa Gambling Task and percentage of N2 sleep, minimal oxygen saturation, average oxygen saturation and time spent below 90% oxygen saturation level. Also, the minimal oxygen saturation accounted for 27% of variance in decision-making. In conclusion, this study shows that a subgroup of patients with obstructive sleep apnea may be at risk of disadvantageous decision-making under ambiguity. Among the sleep-related factors, oxygen saturation is a significant predictor of advantageous decision-making.

    Full Text Available Aim. To study effect of fluoxetine on sleep architecture in patients with metabolic syndrome and obstructive sleep apnea syndrome.Material and methods. 98 patients with obstructive sleep apnea syndrome and metabolic syndrome (aged 54.3±8.7 y.o. were included into the study. All patients received fluoxetine 20 mg once daily during 6 months. Influence of fluoxetine on sleep architecture was evaluated with special questionnaire and by polysomnography, including electroencephalogram, electrooculogram, mentalis electromyogram and pulseoxymetry.Results. Decrease in wake time after sleep onset (Δ33%; р<0.05 was found at the end of treatment. It resulted in improvement of sleep efficacy index. Decrease in respiratory sleep disorders index (Δ20% and rising of blood oxygen saturation (Δ12%; р<0.05 was also found. Improvement of the sleep architecture (reduction in the 2nd phase of slow wave sleep by 15%, increase in delta-sleep (Δ71% and rapid eye movement sleep (Δ25%; р<0.05 was also observed. Besides reduction in body mass index after fluoxetine therapy (Δ12%; р<0.05 was found. Serious adverse effects were not registered.Conclusion. Fluoxetine use in patients with metabolic syndrome and obstructive sleep apnea syndrome shown positive effect on objective indices of sleep architecture and respiratory sleep disorders. It improved adaptive function of the sleep and contributed to reduction in sleep disorders.

  4. Radiologic evaluation of adenoids and tonsils in children with obstructive sleep apnea: Plain films and fluoroscopy

    International Nuclear Information System (INIS)

    Twenty-six children with obstructive sleep apnea were evaluated by lateral neck radiographs during wakefulness, and by polygraphic monitoring and upper airway fluoreoscopy during natural sleep. Children with craniofacial abnormalities, palatal surgery, and central nervous system disease were excluded from the study. Moderate or marked enlargement of tonsils and adenoids was noted on lateral neck radiographs of 18 of 26 patients. An objective measure of adenoidal enlargement, the adenoidal-nasopharyngeal ratio, correlated well with subjective judgment of adenoidal size but was not generally more useful than subjective estimation. Upper airway fluroescopy demonstrated the site and mechanism of obstruction in all patients. Because all children with moderate to marked adenotonsillar enlargement demonstrated obstruction at the adenoidal or tonsillar level on fluoroscopy, we now screen children with suspected sleep apnea with lateral airway radiographs and polysomnography. Fluoroscopy is reserved for children with mild adenotosillar enlargement, craniofacial dysplasia, prior cleft palate repair, or neuromuscular disorders. These results suggest that the pathogenesis of obstuctive sleep apnea in children involve anatomic factors which narrow the upper airway, sleep-related hypotonia of pharyngeal dilator musculature, and compensatory mechanisms to prevent or alleviate asphyxia.

  5. Relationship between the severity of obstructive sleep apnea syndrome and asymptomatic cerebrovascular disease

    International Nuclear Information System (INIS)

    In this study, examined were prevalence of asymptomatic cerebrovascular disease (ACD) in patients with obstructive sleep apnea syndrome (OSAS) and relationship between its severity and ACD prevalence. Subjects were 192 cases (M 170/F 20, av. age 50.6 y) with chief complaint of snore, sleep apnea (apnea-hypopnea index/AHI 0-118.4/h), midday drowsiness and so on without CD history, who underwent the overnight polysomnographic recording, vascular risk assessment like life habits, blood pressure and impaired GT, and brain MRI. The last item was conducted with Siemence 1.5T machine to get T1-, T2-weighted and FLAIR images to evaluate asymptomatic lacunar infarction (ALI) and periventricular hyperintensity (PVH). Light (AHI<15/h), moderate (15≤AHI<30) and severe (AHI≥30) OSASs were found in 44, 35 and 61 cases, respectively. ALIs were found in 7 light, 17 moderate and 61 severe cases and PVH, in 9, 19 and 61 cases, respectively. Thus it was revealed that patients with moderate to severe OSAS had complication of ACD in a higher rate than those with light OSAS and that prevalence of ACD was higher in OSAS patients with AHI 15/h or more.

    An understanding of the potential mechanisms underlying recurrent upper airway collapse may help anesthesiologists better manage patients in the postoperative period. There is convincing evidence in the sleep medicine literature to suggest that a positive fluid and salt balance can worsen upper airway collapse in patients with obstructive sleep apnea through the redistribution of fluid from the legs into the neck and upper airway while supine, in a process known as "rostral fluid shift." According to this theory, during the day the volume from a fluid bolus or from fluid overload states (i.e., heart failure and chronic kidney disease) accumulates in the legs due to gravity, and when a person lies supine at night, the fluid shifts rostrally to the neck, also owing to gravity. The fluid in the neck can increase the extraluminal pressure around the upper airways, causing the upper airways to narrow and predisposing to upper airway collapse. Similarly, surgical patients also incur large fluid and salt balance shifts, and when recovered supine, this may promote fluid redistribution to the neck and upper airways. In this commentary, we summarize the sleep medicine literature on the impact of fluid and salt balance on obstructive sleep apnea severity and discuss the potential anesthetic implications of excessive fluid and salt volume on worsening sleep apnea.

    Obstructive sleep apnea (OSA) is a medical condition characterized by repetitive partial or complete occlusion of the airway during sleep. The soft tissues in the airway of OSA patients are prone to collapse under the low-pressure loads incurred during breathing. This paper describes efforts toward the development of a numerical tool for simulation of air-tissue interactions in the upper airway of patients with sleep apnea. A procedure by which patient-specific airway geometries are segmented and processed from dental cone-beam CT scans into signed distance fields is presented. A sharp-interface embedded boundary method based on the signed distance field is used on Cartesian grids for resolving the airflow in the airway geometries. For simulation of structure mechanics with large expected displacements, a cut-cell finite element method with nonlinear Green strains is used. The fluid and structure solvers are strongly coupled with a partitioned iterative algorithm. Preliminary results are shown for flow simulation inside the three-dimensional rigid upper airway of patients with obstructive sleep apnea. Two validation cases for the fluid-structure coupling problem are also presented.

    Full Text Available Objectives: to stratify the risk for obstructive sleep apnea in patients with acute myocardial infarction, treated at a public, tertiary, teaching hospital of the state of São Paulo, Brazil, and to identify related sociodemographic and clinical factors.Method: cross-sectional analytical study with 113 patients (mean age 59.57 years, 70.8% male. A specific questionnaire was used for the sociodemographic and clinical characterization and the Berlin Questionnaire for the stratification of the risk of obstructive sleep apnea syndrome.Results: the prevalence of high risk was 60.2% and the outcome of clinical worsening during hospitalization was more frequent among these patients. The factors related to high risk were body mass index over 30 kg/m2, arterial hypertension and waist circumference indicative of cardiovascular risk, while older age (60 years and over constituted a protective factor.Conclusion: considering the high prevalence of obstructive sleep apnea and its relation to clinical worsening, it is suggested that nurses should monitor, in their clinical practice, people at high risk for this syndrome, guiding control measures of modifiable factors and aiming to prevent the associated complications, including worsening of cardiovascular diseases.

    Full Text Available Obstructive Sleep Apnea Syndrome is treated not only with the help of nCPAP but by other means which help to support the sufficient level of pharyngeal airways. In course of our experiment we investigated changes in parameters of breath during night sleep in patients with high indices of obstructive Sleep Apnea Syndrome after the tongue muscle training. 40 patients with OSAS treated only with the help of nCPAP underwent a 5-week course of electrical stimulation of upper pharyngeal muscles. This type of treatment was supposed to result in dilatation of pharyngeal airways and cure of occlusion and obstruction. Parameters of breath during the night sleep before- and after the treatment were detected with the help of somno-poligraphic investigations and compared. Indices of apnea and hypopnea decreased in 26 of 40 patients, which is more than half of the probands. We recommended the patients with a diagnosed OSAS without a risk of recurrence to add tongue muscle training to nCPAP. In case the course of nCPAP therapy is launched it helped achieve sufficient improvement of parameters affecting breath during the night sleep and in many cases decrease respiratory pressure of nCPAP therapy or its complete cessation.

    The area of upper airway (from the nasopharynx to the hypopharynx) was measured by means of computed tomography (CT) scan in 15 confirmed cases of obstructive sleep apnea (OSA) and in 4 normal controls while they were awake. The minimum cross-sectional area (MA) of the upper airway was 14.7+-20.0 mm{sup 2} in OSA patients and 80.0+-33.1 mm{sup 2} in normal controls and the difference was statistically significant (p<0.01). In OSA patients, MA did not correlate with age, body weight, apnea index, desaturation index, mean nadir-SO{sub 2} and lowest SO{sub 2}. MA was also measured with OSA patients while nasal continuous positive airway pressure (NCPAP) of 10 cmH{sub 2}O was applied and it was found that MA was significantly widened when NCPAP therapy was performed. We conclude that upper airway narrowing is consistent finding in OSA patients but the degree of narrowing does not correlate with parameters of apnea and gas exchange during sleep, and NCPAP is effective to widen the area of upper airway in OSA patients.

    Full Text Available Overnight polysomnography is the gold standard for the detection of obstructive sleep apnea-hypopnea syndrome (OSAS. However, it is expensive and needs attending personnel. The study of simplified sleep apnea monitoring is one of the recent trends for sleep medicine research. The proposed clinical prediction rules employ the vital and social statistics, symptoms, craniofacial traits, and obesity-related measures for initial screening of OSAS in an ambulatory setting. However, most of them are partially or completely clinical and not home-based. One disadvantage of this sort of screening methods is their inability to asses OSAS severity. Another approach of initial OSAS screening is a usage of just one or two physiological signals such as electrocardiography (ECG, pulse oximetry, snoring, nasal airflow, or even speech sound. In this study, we aimed to review the different strategies and to compare their performances, reported by means of their sensitivity–specificity and accuracy for OSAS incidence and severity. OSAS severity is determined by apnea-hypopnea index (AHI value. Based on the data obtained from the related articles, the most accurate methods of AHI estimation exploit ECG and pulse oximetry signals.

    The aim of this study was to evaluate outcomes related to swallowing function in patients who underwent transoral robotic surgery (TORS) for sleep apnea on both short- and long-term scales. 78 patients who underwent TORS for sleep apnea between 2011 and 2014 were followed up for an average period of 20 ± 7.12 months (range 7-32 months), then swallowing outcomes determined by MD Anderson Dysphagia Inventory (MDADI) questionnaire, gastrografin fluoroscopy imaging results, nasogastric tube dependence and subjectively by recording the patients' complaints were analyzed and reported. Minimal insignificant short-term impact on swallowing function (4.58 ± 7.03 preoperative MDADI score versus 5.18 ± 8.32 post-operative) (p = 0.56) was registered. Mean time for start of oral feeding was 1.05 ± 0.25 days (average, 1-3). In no case nasogastric tube feeding was required. Only five patients (6 %) showed significant aspiration on gastrografin fluoroscopy examination after 1 week; there was no significant correlation between the volume of tissue removed from both tongue base and epiglottis to the incidence of aspiration as shown by gastrografin fluoroscopy examination (p = 0.72). No long-term swallowing complaint was registered. Patients who underwent TORS tongue base reduction and supraglottoplasty for sleep apnea proved to have a reasonable short-term swallowing outcomes with no long-term sequelae.

    Physiological and cellular functions operate in a 24-hour cyclical pattern orchestrated by an endogenous process known as the circadian rhythm. Circadian rhythms represent intrinsic oscillations of biological functions that allow for adaptation to cyclic environmental changes. Key clock genes that affect the persistence and periodicity of circadian rhythms include BMAL1/CLOCK, Period 1, Period 2, and Cryptochrome. Remarkable progress has been made in our understanding of circadian rhythms and their role in common medical conditions. A critical review of the literature supports the association between circadian misalignment and adverse health consequences in sepsis, obstructive lung disease, obstructive sleep apnea, and malignancy. Circadian misalignment plays an important role in these disease processes and can affect disease severity, treatment response, and survivorship. Normal inflammatory response to acute infections, airway resistance, upper airway collapsibility, and mitosis regulation follows a robust circadian pattern. Disruption of normal circadian rhythm at the molecular level affects severity of inflammation in sepsis, contributes to inflammatory responses in obstructive lung diseases, affects apnea length in obstructive sleep apnea, and increases risk for cancer. Chronotherapy is an underused practice of delivering therapy at optimal times to maximize efficacy and minimize toxicity. This approach has been shown to be advantageous in asthma and cancer management. In asthma, appropriate timing of medication administration improves treatment effectiveness. Properly timed chemotherapy may reduce treatment toxicities and maximize efficacy. Future research should focus on circadian rhythm disorders, role of circadian rhythm in other diseases, and modalities to restore and prevent circadian disruption. PMID:27104378

    Background Recent studies showed the central Na+/H+ exchanger type 3 (NHE3) has a close relationship with ventilation control.The objective of the study is to investigate the role of NHE3 in sleep apnea in Sprague-Dawley (SD) rats.Methods A sleep study was performed on 20 male SD rats to analyze the correlation between the sleep apneic events and total NHE3 protein content and inactive NHE3(pS552) in the brainstem measured by Western blotting.Another 20 adult male SD rats received 3 days of sleep and respiration monitoring for 6 hours a day,with adaption on the first day,0.5% DMSO microinjection into the fourth ventricle on the second day,and AVE0657 (specific inhibitor of NHE3) microinjection on the third day.Rats were divided into two groups with injection of 5 μmol/L or 8 μmol/L AVE0657 before the sleep study.The effects of AVE0657 on sleep apnea and sleep structure of rats were analyzed through self-control.Results The total post-sigh apnea index (TPSAI) and post-sigh apnea index in non-rapid eye movement (NREM) sleep (NPSAI) and total apnea index (AI) in NREM sleep (NAI) were negatively correlated with NHE3(pS552) protein contents in the brainstem (r=-0.534,-0.547 and-0.505,respectively,P<0.05).The spontaneous apnea index in REM sleep (RSPAI) was positively correlated with the level of NHE3(pS552) protein expression in the brainstem (r=0.556,P<0.05).However,the sleep AI had no relationship with total NHE3 protein.Compared with the blank control and microinjection of 0.5% DMSO,5 μmol/L AVE0657 significantly reduced the total AI and NPSAI (both P<0.05) without a significant effect on sleep architecture.In contrast to blank control and microinjection of 0.5% DMSO,injection of 8 μmol/L AVE0657 significantly reduced the AI and PSAI in NREM and REM sleep (all P<0.05).Conclusions The severity of sleep apnea was negatively correlated with central inactive NHE3.A specific inhibitor of NHE3 decreased the sleep AI.Thus,our results indicate that central

    Sleep apnea and obesity are strongly associated, and both increase the risk for coronary artery disease. Several cross-sectional studies have reported discrepant results regarding the role obesity plays in the relation between sleep apnea and coronary artery calcium (CAC), a marker of subclinical coronary disease. The aim of the present study was to investigate the association between sleep apnea and the presence of CAC in a community cohort of middle-aged men and women without preexisting cardiovascular disease, stratified by body mass index (0. Sleep apnea was analyzed categorically using the apnea-hypopnea index. The sample was composed of primarily men (61%) and Caucasians (56%), with a mean age of 61 years. The prevalence of CAC was 76%. In participants with body mass indexes <30 kg/m(2) (n = 139), apnea-hypopnea index ≥15 (vs <5) was associated with 2.7-fold odds of having CAC, but the effect only approached significance. Conversely, in participants with body mass indexes ≥30 kg/m(2), sleep apnea was not independently associated with CAC. In conclusion, sleep apnea is independently associated with early atherosclerotic plaque burden in nonobese patients.

    This study proposes a method of automatically classifying sleep apnea/hypopnea events based on sleep states and the severity of sleep-disordered breathing (SDB) using photoplethysmogram (PPG) and oxygen saturation (SpO2) signals acquired from a pulse oximeter. The PPG was used to classify sleep state, while the severity of SDB was estimated by detecting events of SpO2 oxygen desaturation. Furthermore, we classified sleep apnea/hypopnea events by applying different categorisations according to the severity of SDB based on a support vector machine. The classification results showed sensitivity performances and positivity predictive values of 74.2% and 87.5% for apnea, 87.5% and 63.4% for hypopnea, and 92.4% and 92.8% for apnea + hypopnea, respectively. These results represent better or comparable outcomes compared to those of previous studies. In addition, our classification method reliably detected sleep apnea/hypopnea events in all patient groups without bias in particular patient groups when our algorithm was applied to a variety of patient groups. Therefore, this method has the potential to diagnose SDB more reliably and conveniently using a pulse oximeter. PMID:26261097

    Full Text Available ntroduction: Considering the high prevalence of obstructive sleep apnea syndrome (OSAS and its complications, proper diagnosis and treatment is particularly important. Since the standard diagnostic test for OSAS is polysomnography, which is not widely available, finding a simple, available, and cheap diagnostic method is very helpful. The aim of this study was to evaluate the efficiency of anterior rhinomanometry and upper respiratory tract examination in diagnosis of the OSAS. Materials and Methods: In this observational analytic study, all patients referred to BAMDAD sleep clinic for polysomnography from Feb 2007 to Jul 2007 were evaluated by anterior rhinomanometry as well as upper respiratory tract examination and results were compared with each other. Results: Of 66 patients participated in our study, 31 patients were in the normal group, 19 in mild apnea group, and 16 in moderate to severe apnea group. The results of ENT examination showed clear obstruction in 22 patients. 12 of them were in moderate to severe apnea group, and 9 of them in mild apnea group. Only one patient with abnormal examination was in the normal group. The respiratory tract resistance which was measured by anterior rhinomanometry showed no significant association with positive results of polysomnography. Conclusion: Our study showed that although anterior rhinomanometry is invalid for diagnosis of OSAS, ENT examination (such as noctural oxymetry can be a useful diagnostic method for OSAS.

    Introduccion. El sindrome de apnea obstructiva del sueño (SAOS) se asocia frecuentemente a otras enfermedades que actuan como factores de riesgo que influyen en la morbilidad y mortalidad del SAOS. Objetivos. Analizar la presencia de comorbilidades en pacientes con SAOS, seleccionados en una clinica del sueño ambulatoria en el norte de Portugal y clasificados atendiendo a la gravedad del SAOS. Pacientes y metodos. Una cohorte de 319 pacientes con trastornos del sueño fueron evaluados mediante estudios clinicos y registro videopoligrafico durante el sueño. Del total de pacientes (n = 209) con distres respiratorio durante el sueño, 145 tenian SAOS con gravedad definida segun el indice de apnea/hipopnea (IAH); 64 presentaban ronquidos primarios o distres respiratorio con IAH respiratorio durante el sueño, la comorbilidad aparece normalmente relacionada con el SAOS (p = 0,0196). Conclusion. Las comorbilidades se asocian con frecuencia al SAOS, independientemente de la gravedad de la enfermedad. Entre las comorbilidades presentes, la obesidad resulto ser la mas comun en los casos mas graves de SAOS.

    Full Text Available BACKGROUND: The gender-specific influences of various confounding factors, including apnea, age, BMI, and cigarette consumption, on the function of the parasympathetic nerve system (PNS during sleep in OSA patients has never been investigated. METHODS: One hundred ninety-seven males and 63 females with OSA were subjected to full PSG examinations including assessment of R-R intervals (RRIs during an overnight ECG. The PNS-derived modulatory effect on the RRIs and the variability of this effect were quantified during REM and NREM using instantaneous time-frequency analysis with complex demodulation. The spectral domain with the maximum instantaneous amplitude in the high-frequency band between 0.15 and 0.4 Hz was defined as the main HF peak and used as a surrogate marker of PNS discharge. Based on density-spectrum-array maps of the main HF peaks (HF-DSA map, shifts in the central frequency of the main HF peak over time were continuously observed. When the main HF peaks on the HF-DSA maps maintained the same central frequency for more than 20 sec or 5 min, the PNS functions were considered to be "stable" or "very stable", respectively. RESULTS: Apneas enhanced PNS-derived cardiac-modulation during REM in males, but more importantly, they made PNS-function unstable during both REM and NREM in males and during NREM in females. Aging blunted the PNS-derived cardiac-modulation during both REM and NREM regardless of gender, but aging had no impact on the stability of PNS-function. BMI blunted PNS-eliciting cardiac-modulation during REM in males and during NREM in both males and females. BMI made the PNS unstable during REM in females. Neither height nor cigarette consumption influenced any PNS-related parameter. CONCLUSIONS: The PNS-derived cardiac-modulation was generally inhibited by aging and obesity, in which the effect of obesity was gender-specific. The PNS instability at nighttime was mainly induced by apneas but by obesity particularly during

    Full Text Available OBJECTIVE: There are several treatments for obstructive sleep apnea syndrome, such as weight loss, use of an oral appliance and continuous positive airway pressure, that can be used to reduce the signs and symptoms of obstructive sleep apnea syndrome. Few studies have evaluated the effectiveness of a physical training program compared with other treatments. The aim of this study was to assess the effects of physical exercise on subjective and objective sleep parameters, quality of life and mood in obstructive sleep apnea patients and to compare these effects with the effects of continuous positive airway pressure and oral appliance treatments. METHODS: Male patients with moderate to severe obstructive sleep apnea and body mass indices less than 30 kg/m2 were randomly assigned to three groups: continuous positive airway pressure (n = 9, oral appliance (n = 9 and physical exercise (n = 7. Polysomnographic recordings, blood samples and daytime sleepiness measurements were obtained prior to and after two months of physical exercise or treatment with continuous positive airway pressure or an oral appliance. Clinicaltrials.gov: NCT01289392 RESULTS: After treatment with continuous positive airway pressure or an oral appliance, the patients presented with a significant reduction in the apnea-hypopnea index. We did not observe changes in the sleep parameters studied in the physical exercise group. However, this group presented reductions in the following parameters: T leukocytes, very-low-density lipoprotein and triglycerides. Two months of exercise training also had a positive impact on subjective daytime sleepiness. CONCLUSIONS: Our results suggest that isolated physical exercise training was able to modify only subjective daytime sleepiness and some blood measures. Continuous positive airway pressure and oral appliances modified the apnea-hypopnea index.

    Full Text Available Background  Apnea is one of the most common problems in preterm neonates. This study aimed to evaluate the effectiveness of aromatherapy on the reduction of apnea, bradycardia, and Pulse Oximetry (SPO2 in premature infants. Materials and Methods In a clinical trial study, 60 preterm neonates randomly divided in two groups and exposed to aromatherapy with Rosa damascenes distillate or distilled water beside the routine treatment. In experimental group, two drops of 10% Rosa damascenes distillate was dropped on the pad eye in second day of birth at 6 Am. The intervention was repeated in 9 AM, 12 Am, 15 PM and 18 PM hours. A same condition applied for control group and distilled water was dropped on the pad eye. The number of apnea attacks, bradycardia and decrease in SpO2 compared between two groups using chi-square test, independent t-test and repeated measure test. Results The overall apnea attacks, bradycardia, and SPO2 in tree studied days were lower in intervention group than control group (0.47±0.13 vs. 2.6±0.41, 0.47±0.13 vs. 2.56±0.41 and 0.70±0.17 vs. 2.77±0.21, respectively. In addition, the repeated measurement test showed that the mean number of apnea attacks, decrease in heart pulse rate, and decrease in SpO2 was statistically lower in intervention group with aromatherapy than controls in first, second, third and sum of three days (P< 0.05. Conclusion Aromatherapy with Rosa damascenes distillate can reduce more and speedy the occurrence of apnea attacks, bradycardia and SPO2 in premature infants, along with other routine treatment.

    Full Text Available Although obstructive sleep apnea (OSA is known to have a strong familial basis, no genetic polymorphisms influencing apnea risk have been identified in cross-cohort analyses. We utilized the National Heart, Lung, and Blood Institute (NHLBI Candidate Gene Association Resource (CARe to identify sleep apnea susceptibility loci. Using a panel of 46,449 polymorphisms from roughly 2,100 candidate genes on a customized Illumina iSelect chip, we tested for association with the apnea hypopnea index (AHI as well as moderate to severe OSA (AHI≥15 in 3,551 participants of the Cleveland Family Study and two cohorts participating in the Sleep Heart Health Study.Among 647 African-Americans, rs11126184 in the pleckstrin (PLEK gene was associated with OSA while rs7030789 in the lysophosphatidic acid receptor 1 (LPAR1 gene was associated with AHI using a chip-wide significance threshold of p-value<2×10(-6. Among 2,904 individuals of European ancestry, rs1409986 in the prostaglandin E2 receptor (PTGER3 gene was significantly associated with OSA. Consistency of effects between rs7030789 and rs1409986 in LPAR1 and PTGER3 and apnea phenotypes were observed in independent clinic-based cohorts.Novel genetic loci for apnea phenotypes were identified through the use of customized gene chips and meta-analyses of cohort data with replication in clinic-based samples. The identified SNPs all lie in genes associated with inflammation suggesting inflammation may play a role in OSA pathogenesis.

    Sleep apnea is a form of sleep-disordered breathing that is associated with an increase in disease comorbidities, mortality risks, health care costs, and traffic accidents. Sleep apnea is most commonly treated with positive airway pressure (PAP). PAP can be difficult for patients to tolerate. This leads to initial and long-term noncompliance. Most insurance companies require compliance with PAP treatment to cover ongoing reimbursements for the device and related disposable supplies. Therefore, there are both clinical and financial incentives to a sleep apneic patient's compliance with PAP therapy.

    Full Text Available A transitory increase in blood pressure (BP is observed following upper airway surgery for obstructive sleep apnea syndrome but the mechanisms implicated are not yet well understood. The objective of the present study was to evaluate changes in BP and heart rate (HR and putative factors after uvulopalatopharyngoplasty and septoplasty in normotensive snorers. Patients (N = 10 were instrumented for 24-h ambulatory BP monitoring, nocturnal respiratory monitoring and urinary catecholamine level evaluation one day before surgery and on the day of surgery. The influence of postsurgery pain was prevented by analgesic therapy as confirmed using a visual analog scale of pain. Compared with preoperative values, there was a significant (P < 0.05 increase in nighttime but not daytime systolic BP (119 ± 5 vs 107 ± 3 mmHg, diastolic BP (72 ± 4 vs 67 ± 2 mmHg, HR (67 ± 4 vs 57 ± 2 bpm, respiratory disturbance index (RDI characterized by apnea-hypopnea (30 ± 10 vs 13 ± 4 events/h of sleep and norepinephrine levels (22.0 ± 4.7 vs 11.0 ± 1.3 µg l-1 12 h-1 after surgery. A positive correlation was found between individual variations of BP and individual variations of RDI (r = 0.81, P < 0.01 but not between BP or RDI and catecholamines. The visual analog scale of pain showed similar stress levels on the day before and after surgery (6.0 ± 0.8 vs 5.0 ± 0.9 cm, respectively. These data strongly suggest that the cardiovascular changes observed in patients who underwent uvulopalatopharyngoplasty and septoplasty were due to the increased postoperative RDI.

    2015-01-01

    Full Text Available Obstructive sleep apnea (OSA and obstructive sleep apnea syndrome (OSAS are subsets of sleep-disordered breathing. Awareness about OSA and its consequences among the general public as well as the majority of primary care physicians across India is poor. This necessitated the development of the Indian initiative on obstructive sleep apnea (INOSA guidelines under the auspices of Department of Health Research, Ministry of Health and Family Welfare, Government of India. OSA is the occurrence of an average five or more episodes of obstructive respiratory events per hour of sleep with either sleep-related symptoms or co-morbidities or ≥15 such episodes without any sleep-related symptoms or co-morbidities. OSAS is defined as OSA associated with daytime symptoms, most often excessive sleepiness. Patients undergoing routine health check-up with snoring, daytime sleepiness, obesity, hypertension, motor vehicular accidents, and high-risk cases should undergo a comprehensive sleep evaluation. Medical examiners evaluating drivers, air pilots, railway drivers, and heavy machinery workers should be educated about OSA and should comprehensively evaluate applicants for OSA. Those suspected to have OSA on comprehensive sleep evaluation should be referred for a sleep study. Supervised overnight polysomnography is the "gold standard" for evaluation of OSA. Positive airway pressure (PAP therapy is the mainstay of treatment of OSA. Oral appliances (OA are indicated for use in patients with mild to moderate OSA who prefer OA to PAP, or who do not respond to PAP or who fail treatment attempts with PAP or behavioral measures. Surgical treatment is recommended in patients who have failed or are intolerant to PAP therapy.

    Background: Obstructive sleep apnea-hypopnea syndrome (OSAS) is associated with elevated liver enzymes and fatty liver.The purpose of this study was to measure serum liver enzyme levels in patients evaluated by polysomnography (PSG) and the factors associated with liver injury in OSAS patients.Methods: All patients referred to PSG for evaluation of sleep apnea symptoms between June 2011 and November 2014 were included in this study.Demographic data and PSG parameters were recorded.Serum alanine aminotransferase, aspartate aminotransferase, and gamma-glutamyl transferase levels were systematically measured.OSAS patients were divided into mild, moderate, and severe groups according to the apnea-hypopnea index (AHI) values of 5-14 events/h, 15-29 events/h, and ≥30 events/h.Results: A total of 540 patients were enrolled in this study;among these patients, 386 were male.Elevated liver enzymes were present in 42.3% of OSAS patients (32.4% in mild/moderate group;51.0% in severe group) and 28.1% patients without OSAS.Patients with OSAS had higher body mass index (BMI) (P < 0.01).In the bivariate correlation, the liver enzymes level was negatively correlated with age and the lowest arterial oxygen saturation (SaO2), and was positively correlated with BMI, oxygen desaturation index, percent of total time with oxygen saturation level <90% (TS90%), AHI, total cholesterol (TC), and triglyceride (TG).In logistic regression analysis, Age,BMI, TS90%, TC, and TG were included in the regression equation.Conclusions: Our data suggest that OSAS is a risk factor for elevated liver enzymes.The severity of OSAS is correlated with liver enzyme levels;we hypothesize that hypoxia is one of main causes of liver damage in patients with OSAS.

    Rationale: Obstructive sleep apnea (OSA) has been associated with a number of chronic disorders that may improve with effective therapy. However, the molecular pathways affected by continuous positive airway pressure (CPAP) treatment are largely unknown. We sought to assess the system-wide consequences of CPAP therapy by transcriptionally profiling peripheral blood leukocytes (PBLs). Methods: Subjects in whom severe OSA was diagnosed were treated with CPAP, and whole-genome expression measurement of PBLs was performed at baseline and following therapy. We used gene set enrichment analysis (GSEA) to identify pathways that were differentially enriched. Network analysis was then applied to highlight key drivers of processes influenced by CPAP. Results: Eighteen subjects with significant OSA underwent CPAP therapy and microarray analysis of their PBLs. Treatment with CPAP improved apnea-hypopnea index (AHI), daytime sleepiness, and blood pressure, but did not affect anthropometric measures. GSEA revealed a number of enriched gene sets, many of which were involved in neoplastic processes and displayed downregulated expression patterns in response to CPAP. Network analysis identified several densely connected genes that are important modulators of cancer and tumor growth. Conclusions: Effective therapy of OSA with CPAP is associated with alterations in circulating leukocyte gene expression. Functional enrichment and network analyses highlighted transcriptional suppression in cancer-related pathways, suggesting potentially novel mechanisms linking OSA with neoplastic signatures.
