1. Obstructive sleep apnea and Parkinson's disease: characteristics and associated factors
RESUMO A Apneia Obstrutiva do Sono (AOS) chega a acometer até 66% dos pacientes com doença de Parkinson (DP), prevalência maior, portanto, que a da população geral. Embora seja mais prevalente, a relação entre AOS e DP permanence controversa, com trabalhos confirmando e outros afastando a relação de AOS com alguns fatores de risco e sintomas em paci

2. Clinical and polysomnographic predictors of laryngopharyngeal reflux in obstructive sleep apnea syndrome
Resumo Introdução A síndrome da apneia obstrutiva do sono e o refluxo laringofaríngeo são doenças com alta prevalência na população em geral. No entanto, ainda não está claro se são doenças com os mesmos fatores de risco presentes nas mesmas populações ou se há alguma relação entre elas. Objetivo Avaliar e determinar a prevalência de ref

3. Treatment of snoring and sleep apnea syndrome with a removable mandibular advancement device in patients without TMD
INTRODUCTION: Among the sleep disorders reported by the American Academy of Sleep, the most common is obstructive sleep apnea-hypopnea syndrome (OSAHS), which is caused by difficulties in air passage and complete interruption of air flow in the airway. This syndrome is associated with increased morbidity and mortality in apneic individuals. OBJECTIVE: It was

4. Effects of sildenafil on autonomic nervous function during sleep in obstructive sleep apnea
OBJECTIVE: To evaluate the effects of sildenafil on the autonomic nervous system in patients with severe obstructive sleep apnea. METHODS: Thirteen male patients with severe obstructive sleep apnea (mean age 43±10 years with a mean body mass index of 26.7±1.9 kg/m²) received a single 50-mg dose of sildenafil or a placebo at bedtime. All-night polysomnogra

5. Effect of smoking habits on sleep
To evaluate the effect of smoking habits on sleep, data from 1492 adults referred to the Sleep Institute were accessed and divided into 3 categories of smoking status: current, former and non-smokers. Categories of pack-years (<15 and ≥15) defined smoking severity. The association of smoking status and smoking severity with sleep was analyzed for sleep par

6. Ambulatory blood pressure monitoring in patients with chronic obstructive pulmonary disease with sleep desaturation / Monitorização ambulatorial da pressão arterial em portadores de doença pulmonar obstrutiva crônica com dessaturação no sono
Introduction: The hypoxemia during the sleep period can, by a sympathetic activation mechanism, change the blood pressure. Few studies show the alterations of the blood pressure, during the sleep period, in chronic obstructive pulmonary disease patients that do not have sleep apnea, but do desaturate during this period. Objective: To analyze the arterial pre

7. Heart Rate Variability in Patients with Chronic Obstructive Lung Disease and Nocturnal Oxygen Desaturation / Análise da Variabilidade da Freqüência Cardíaca em Pacientes Portadores de Doença Pulmonar Obstrutiva Crônica e Dessaturação Noturna
Background: The autonomic nervous system may be disturbed in chronic respiratory failure. Chronic hypoxemia may result in sympathetic activation. There are few studies showing the role of the autonomic nervous system in patients with chronic obstructive lung disease (COPD) and nocturnal oxygen desaturation. Objective: To analyze the sympathetic and parasympa

8. Avaliação polissonográfica e de função cardio-respiratória de adolescentes portadores de anemia falciforme clinicamente estáveis
Introduction: sickle cell anemia is the most prevalent hereditary disease in Brazil, occurring in 0,1 to 0,3% of the negro population. The occurrence of 1-3/1000 new annual cases in the country are also estimated, thus characterizing an important public health problem in our environment. Its also know that the prevalence of nocturnal desaturation of hemoglob

9. Alterações da estrutura e função respiratórias durante a vigília e o sono na acromegalia
Purposes: Patients with acromegaly have increased mortality due to respiratory disease when compared to whole population. Hypoxemia secondary to sleep apnea is commonly seen in patients with acromegaly, and this alteration apparently leads to considerable morbidity and mortality among such patients. This research has the objective of identifying hypoxemia ba

10. "Desenvolvimento de monitor de oximetria contínua para diagnóstico de apnéia obstrutiva do sono na unidade coronária" / Development of a continuous overnight oximetry monitor for the diagnosis of obstructive sleep apnea in the coronary care unit.
BACKGROND: A high prevalence of Obstructive sleep apnea (OSA) has been reported in patients with coronary artery disease (CAD). Several OSA related mechanisms, such as oxygen desaturation, high sympathetic activity, increased cardiac oxygen demand and a prothrombotic state, may be particularly dangerous in acute CAD patients. Nevertheless, OSA is frequently

11. Non-apnoeic REM sleep induced nocturnal oxygen desaturation treated by nasal continuous positive airway pressure.
Non-apnoeic oxygen desaturation related to rapid eye movement (REM) sleep in a patient with hypothyroidism, obesity, respiratory failure, and cardiac failure was improved by treatment with nasal continuous positive airway pressure of 10 cm H2O.

12. Nocturnal hypoxaemia and quality of sleep in patients with chronic obstructive lung disease.
Fifty patients with chronic obstructive lung disease were questioned about their sleep quality and their responses were compared with those of 40 similarly aged patients without symptomatic lung disease. Patients with chronic obstructive lung disease reported more difficulty in getting to sleep and staying asleep and more daytime sleepiness than the control
