The aim of this study was to analyze one year survival outcome of the patients with sleep apnea in acute stroke in order to type and localisation of lesion. Patients and Methods: It was analyzed 110 patients with acute stroke (AS) and verified sleep apnea, treated at Department of Neurology, University Clinical Center Tuzla in the period December 2009 thorough may 2010. Acute stroke has been ve...
Sleep apnea syndrome (SAS) often presents a difficult therapeutic problem to the clinician since many of the accepted modes of therapy are associated with only partial success or with a number of long-term complications. We present three patients with obstructive SAS in whom dramatic clinical improvement occurred following repair of a deviated nasal septum. The subjective improvement was associ...
What We Found § Though far fewer than the 1995 study found, 4.7% of commercial drivers in the study were found to have severe sleep apnea. Another 5.8% had moderate sleep apnea and 17.6% has mild sleep apnea. § Prevalence of moderate to severe sleep apnea is twice as high among CDL holders no longer currently employed as drivers, suggesting that the industry may be losing valuable drivers becau...
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-seve...
INTRODUCTION Obstructive sleep apnea (OSA) is the most common form of sleep disordered breathing and has been associated with major cardiovascular comorbidities. We hypothesized that the microcirculation is impaired in patients with OSA and that the magnitude of impairment correlates to OSA severity. METHODS Subjects were consecutive patients scheduled for routine diagnostic polysomnography (...
BACKGROUND Obstructive sleep apnea (OSA) is a major risk factor for perioperative adverse events. However, no screening tool for OSA has been validated in surgical patients. This study was conducted to develop and validate a concise and easy-to-use questionnaire for OSA screening in surgical patients. METHODS After hospital ethics approval, preoperative patients aged 18 yr or older and withou...
STUDY OBJECTIVES Identify polysomnographic and demographic factors associated with elevation of nocturnal end-tidal CO2 in patients with obstructive sleep apnea. METHODS Forty-four adult patients with obstructive sleep apnea were selected such that the maximal nocturnal end-tidal CO2 was below 45 mm Hg in 15 studies, between 45 and 50 mm Hg in 14, and above 50 mm Hg in 15. Measurements includ...
STUDY OBJECTIVES Some patients with apparent obstructive sleep apnea hypopnea syndrome (OSAHS) have elimination of obstructive events but emergence of problematic central apneas or Cheyne-Stokes breathing pattern. Patients with this sleep-disordered breathing problem, which for the sake of study we call the "complex sleep apnea syndrome," are not well characterized. We sought to determine the p...
OBJECTIVE To examine whether circulating leptin levels correlate with the severity of disease in patients with obstructive sleep apnea. DESIGN Prospective nonrandomized study. SETTING Referral sleep laboratory for patients with sleep-disordered breathing and biochemistry laboratory. Patients Thirty-two subjects (mean +/- SD age, 47 +/- 12 years) who were referred for suspected sleep apnea u...
OBJECTIVE To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. METHODS We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth ...
