OBJECTIVE The localization of upper airway obstruction in patients with obstructive sleep apnea (OSA) may optimize treatment. Nasoendoscopy during propofol sedation allows such an evaluation, but the effect of this drug on respiratory patterns and muscle relaxation is unknown. The objective of the present study was to determine through polysomnography(More)
UNLABELLED Only a few studies have compared the outcomes of patients kept awake during endoscopic examination and subjects submitted to drug-induced sleep endoscopy. OBJECTIVE This study aimed to compare the endoscopic findings of patients submitted to outpatient endoscopy and endoscopic examination with sedation by propofol based on the Fujita(More)
OBJECTIVES/HYPOTHESIS The treatment for obstructive sleep apnea syndrome (OSAS) depends on correct localization of upper airway obstruction, exception made for continuous positive airway pressure (CPAP). Drug-induced sleep endoscopy (DISE) with propofol allows this evaluation, but the drug effects on sleep parameters are not yet well established. Our(More)
This manuscript contains the conclusion of the consensus meeting on the diagnosis of narcolepsy based on the review of Medline publications between 1980-2010. Narcolepsy is a chronic disorder with age at onset between the first and second decade of life. Essential narcolepsy symptoms are cataplexy and excessive sleepiness. Cataplexy is defined as sudden,(More)
The effect of noradrenaline (NA) injection (20 or 40 nmol) into the preoptic area (POA) on plasma glucose and insulin was studied in male and female rats. The rats were implanted with chronic jugular catheters for blood sampling and unilateral intracerebral cannulas placed just above the POA. Blood samples were taken before and at 5, 10, 15, 30 and 60 min(More)
INTRODUCTION The standard therapy for obstructive sleep apnea syndrome (OSAS) is continuous positive airway pressure (CPAP), but its correct and frequent use is essential to control the disease. PURPOSE To analyze adherence to CPAP among patients with OSAS treated in a multidisciplinary outpatient clinic of a public tertiary hospital. METHODS This was a(More)
This manuscript contains the conclusion of the consensus meeting of the Brazilian Sleep Association with Brazilian sleep specialists on the treatment of narcolepsy based on the review of medical literature from 1980 to 2010. The manuscript objectives were to reinforce the use of agents evaluated in randomized placebo-controlled trials and to issue consensus(More)
BACKGROUND Obstructive sleep apnea (OSA) is frequent in acute stroke patients, and has been associated with higher mortality and worse prognosis. Polysomnography (PSG) is the gold standard diagnostic method for OSA, but it is impracticable as a routine for all acute stroke patients. We evaluated the accuracy of two OSA screening tools, the Berlin(More)
BACKGROUND Obstructive sleep apnea (OSA) is related to increased systemic inflammation and arterial hypertension. We hypothesize that OSA is frequent in patients with acute hypertensive intracerebral hemorrhage (ICH) and is related to the perihematoma edema. METHODS Thirty-two non-comatose patients with a hypertensive ICH underwent polysomnography in the(More)
The aim of the study was to evaluate facial features and hyoid bone position in children with obstructive sleep apnea syndrome (OSAS) by cephalometric radiography. A prospective cross-sectional study was conducted in a tertiary referral hospital. Twenty-nine children in the 3-6 year age bracket were evaluated: 14 children with OSAS and 15 nasal-breathing(More)
