    OBJECTIVE: To investigate the prevalence of obstructive sleep apnea in patients with ischemic stroke and to evaluate the effectiveness of nasal continuous positive airway pressure treatment. METHODS: Overnight polysomnography was performed by a computerized system in 19 subjects with ischemic stroke. Patients with an apnea-hypopnea index >= 5 were considered to have obstructive sleep apnea. The appropriate level of continuous positive airway pressure for each patient was determined during an all-night continuous positive airway pressure determination study. Attended continuous positive airway pressure titration was performed with a continuous positive airway pressure auto-titrating device. RESULTS: Obstructive sleep apnea prevalence among patients with ischemic stroke was 73.7%. The minimum SaO(2) was significantly lower, and the percent of total sleep time in the wake stage and stage 1 sleep was significantly longer in patients with obstructive sleep apnea. In two patients with severe obstructive sleep apnea, we observed a decrease in the apnea-hypopnea index, an increase in mean wake time, mean SaO(2), and minimum SaO(2), and alterations in sleep structures with continuous positive airway pressure treatment. CONCLUSION: As the diagnosis and treatment of obstructive sleep apnea is of particular importance in secondary stroke prevention, we suggest that the clinical assessment of obstructive sleep apnea be part of the evaluation of stroke patients in rehabilitation units, and early treatment should be started.

    Obstructive sleep apnea syndrome as an uncommon cause of fibromyalgia: a case report
    (Springer Heidelberg, 2007) Sepici, Vesile; Tosun, Aliye; Köktürk, Oğuz
    Fibromyalgia syndrome (FMS) is characterized by chronic widespread musculoskeletal pain, stiffness and tenderness at multiple points. Sleep disturbances are common in FMS and patients usually complain about nonrestorative sleep. Obstructive sleep apnea syndrome (OSAS) is characterized by repetitive pharyngeal collapse during sleep. Recurrent arousals from sleep occurs to restore pharyngeal patency in OSAS and this results in increased sympathetic activity and fragmentation of sleep. Sleep disturbances may lead to musculoskeletal pain and some studies suggest a relation between OSAS and FMS. Since OSAS is strongly associated with increased risk of myocardial infarction, cerebrovascular accidents and congestive heart failure, its diagnosis and treatment are of particular importance. Herein we present a female patient with diagnosis of FMS for 10 years who had complaints of morning fatigue, restless sleep, sleepiness during day and snoring besides musculoskeletal symptoms. Severe OSAS was diagnosed after polysomnographic analysis and FMS symptoms were totally improved with nasal continuous positive airway pressure treatment.
