STUDY OBJECTIVE To evaluate and compare outcomes of uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnea/hypopnea syndrome (OSAHS) using anatomy- and severity-based staging systems. DESIGN Prospective design with a retrospective review. SETTING A tertiary-care, sleep disorder referral center. PATIENTS In total, 110 patients with OSAHS (105 men, 5 women; mean age, 43 years; apnea-h...

BACKGROUND AND PURPOSE Convincing evidence of a causal relationship between sleep apnea and stroke has been shown recently in several prospective, well-designed studies. However, these studies have focused on middle-aged people, excluding the elderly population from analysis. To investigate whether sleep apnea represents an independent risk factor in this population, we performed a prospective ...

background: sleep apnea is temporary cessation or absence of breathing during sleep. significant increase in blood pressure is clinically seen in apneic episodes. the aim of this study was to examine sleep apnea syndrome as a risk factor for non- arthritic anterior ischemic optic neuropathy (naion) in a case control study. methods: nineteen naion patients (9 men and 10 women) and 31 age and sex...

BACKGROUND Cardiovascular diseases leading to pacemaker implantations are suspected of being associated with a high rate of undiagnosed sleep apnea syndrome (SAS). We sought to determine the prevalence and consequences of SAS in pacemaker patients according to pacing indications: heart failure, symptomatic diurnal bradycardia, and atrioventricular block. METHODS AND RESULTS Ninety-eight conse...

INTRODUCTION The knowledge on the mechanism of the postoperative exacerbation of sleep-disordered breathing may direct the perioperative management of patients with obstructive sleep apnea. The objective of this study is to investigate the factors associated with postoperative severity of sleep-disordered breathing. METHODS After obtaining approvals from Institutional Review Boards, consentin...

INTRODUCTION ApneaLink™ (RESMED-Munich, Germany) is a simple and inexpensive device that determines the apnea-hypopnea index. The sensitivity and specificity of the apnea-hypopnea index are 100 and 87.5%, respectively. Our hypothesis can be used to create a treatment plan using the apnea-hypopnea index for intensive care unit patients. CASE PRESENTATION This treatment plan has been created by...

OBJECTIVE To identify risk factors for inpatient apnea among children hospitalized with bronchiolitis. METHODS We enrolled 2207 children, aged <2 years, hospitalized with bronchiolitis at 16 sites during the winters of 2007 to 2010. Nasopharyngeal aspirates (NPAs) were obtained on all subjects, and real-time polymerase chain reaction was used to test NPA samples for 16 viruses. Inpatient apne...

INTRODUCTION Obstructive sleep apnea occurs by recurrent collapse of the upper airway during sleep, resulting in total (apnea) or partial (hypopnea) reduction of the airflow and has intimate relation with changes in the upper airway. Cone Beam CT allows the analysis of the upper airway and its volume by three-dimensional reconstruction. OBJECTIVE To evaluate a possible correlation between the...

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...
