The Extracellular Matrix of the Lateral Pharyngeal Wall in Obstructive Sleep Apnea

Study Objectives: To compare the components of the extracellular matrix in the lateral pharyngeal muscular wall in patients with and without obstructive sleep apnea (OSA). This may help to explain the origin of the increased collapsibility of the pharynx in patients with OSA. Design: Specimens from the superior pharyngeal constrictor muscle, obtained during pharyngeal surgeries, were evaluated using histochemical and immunohistochemical analyses to determine the fractional area of collagen types I and II, elastic fibers, versican, fibronectin, and matrix metalloproteinases 1 and 2 in the endomysium. Setting: Academic tertiary center. Patiens: A total of 51 nonobese adult patients, divided into 38 patients with OSA and 13 nonsnoring control subjects without OSA. Interventions: Postintervention study performed on tissues from patients after elective surgery. Measurements and Results: Pharyngeal muscles of patients with OSA had significantly more collagen type I than pharyngeal muscles in control subjects. Collagen type I was correlated positively and independently with age. The other tested components of the extracellular matrix did not differ significantly between groups. In a logistic regression, an additive effect of both the increase of collagen type I and the increase in age with the presence of OSA was observed (odds ratio (OR), 2.06; 95% confidence interval (CI), 1.17-3.63), when compared with the effect of increased age alone (OR, 1.11; 95% CI, 1.03-1.20). Conclusion: Collagen type I in the superior pharyngeal constrictor muscle was more prevalent in patients with OSA and also increased with age. It was hypothesized that this increase could delay contractile-relaxant responses in the superior pharyngeal constrictor muscle at the expiratory-inspiratory phase transition, thus increasing pharyngeal collapsibility.

REM sleep behavior disorder in Parkinson's disease: a questionnaire-based survey

REM sleep behavior disorder (RBD) is reported in up to 50% of patients with Parkinson's disease (PD). Only a few systematic, large-scale studies have addressed the characteristics of RBD in PD. The aim of the present study is to assess the frequency of RBD in patients with PD and the association with PD characteristics.

This layer is a georeferenced raster image of the historic paper map entitled: Blanchard's map of Chicago and suburbs. It was published by Rufus Blanchard in 1910. Scale [ca. 1:49,600]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Illinois East State Plane Coordinate System NAD83 (in Feet) (Fipszone 1201). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, index maps, legends, or other information associated with the principal map. This map shows features such as roads, elevated roads, railroads, railroad stations, street car lines, drainage, selected industry locations, parks and boulevards, city limits and ward boundaries, and more.

Tratamiento quirúrgico del síndrome de apnea hipopnea obstructiva del sueño en la Clínica Rivas, Bogotá – Colombia

Introducción: El Síndrome de Apnea Hipopnea Obstructiva del Sueño es un trastorno respiratorio del sueño mayor ampliamente conocido, con importantes implicaciones para los pacientes y cuya incidencia ha venido en aumento durante los últimos años; comprende diversas manifestaciones clínicas que varían desde el ronquido hasta consecuencias cardiovasculares importantes. Objetivo: Describir la experiencia de los procedimientos quirúrgicos más utilizados para el tratamiento de pacientes con Trastornos Respiratorios del Sueño en la Clínica Rivas. Diseño: Estudio observacional descriptivo. Métodos: Revisión de 366 historias clínicas de pacientes con diagnóstico clínico y Polisomnográfico de SAHOS intervenidos quirúrgicamente debido al Trastorno Respiratorio del Sueño por rechazo de terapia de presión positiva en 3 años de observación. Resultados: Se evaluaron diferencias en medianas de los cambios del IAH, índice de Saturación de oxigeno basal y mínima, y el índice de microdespertares nocturnos tanto prequirúrgica como postquirúrgicamente. Como medida de evaluación secundaria se evaluaron las complicaciones quirúrgicas. Conclusión: En nuestra institución, como centro de referencia en apnea del sueño, la cirugía ha demostrado que disminuye de forma significativa gravedad del SAHOS y disminuye el riesgo de los pacientes con trastornos respiratorios del sueño que han rechazado el dispositivo de presión positiva.
