    CPAP compliance in patients with obstructive sleep apnea syndrome
    (Springer Heidelberg, 2008) Yetkin, Ozkan; Kunter, Erdogan; Gunen, Hakan
    Obstructive sleep apnea syndrome (OSAS) is characterized by repeated cessations of breathing during sleep. Major symptoms of this disease are excessive daytime sleepiness, snoring, and witnessed apnea. Most of the patients are treated with CPAP. In this study, we aimed to evaluate the factors affecting adherence to the CPAP treatment. Seventy-one patients were enrolled to this study. Patients were divided into three groups according to CPAP usage. Group I consisted of patients who had never used CPAP, group II consisted of patients who had used CPAP occasionally, and group-III patients had used CPAP treatment regularly. Group-III patients had higher apnea hypopnea index (AHI) than groups I and II (respectively, 56.6 +/- 27.7, 26.3 +/- 7.5, and 32.3 +/- 7.06; p<0.000 for both). Oxygen desaturation index was significantly higher in group-III patients comparing to groups I and II (44.6 +/- 22.3, 15.9 +/- 8.3, and 25.6 +/- 9.5; p<0.000 for all). Our findings have shown that only very severe patients use the CPAP device regularly (mean AHI 56.6 +/- 27.7). Compliance to CPAP treatment seemed to be poor in patients with moderate to severe, AHI about 30, OSAS. Considering the well-established benefits of CPAP treatment in patients with true indications, patients should be encouraged to use CPAP regularly, and complications of OSAS should be keynoted.

    UARS presenting with the symptoms of anxiety and depression
    (Versita, 2010) Kunter, Erdogan; Yetkin, Ozkan; Gunen, Hakan
    Upper airway resistance syndrome (UARS) is a condition where the apnea-hypopnea index is less than 5 and respiratory-effort related arousal index is more than 10. The clinical presentation of UARS may be the same as obstructive sleep apnea-hypopnea syndrome (OSAS); it sometimes shows up with symptoms hardly suggestive of a sleep-disordered breathing. A 17 year-old male patient had applied to a local psychiatry clinic and complained of chronic fatigue, insomnia, behavioral and academic problems and was treated for anxiety and depression. After a period of unresponsive treatment, he was sent to a sleep center for evaluation of insomnia, which turned out to be a fragmented, unrefreshing sleep episode. Polysomnographical evaluation revealed that he had UARS without OSAS. His complaints decreased dramatically after he received CPAP treatment. This case shows that UARS should be considered in young patients with functional somatic syndromes even if the clinical presentation does not apparently imply the condition.
