The aim of this study was to investigate the reliability and validity of the ESS in the Turkish language. The Turkish version of the ESS (ESStr) was applied to 194 healthy(More)
BACKGROUND There is limited information regarding myocardial alterations in patients with obstructive sleep apnea syndrome (OSAS) in the absence of pulmonary and cardiac comorbidity. In this study, we aimed to evaluate potential myocardial alterations of these patients and investigate the possible effects of OSAS-related pathological variations on left and(More)
BACKGROUND Obstructive sleep apnea syndrome (OSAS) is characterized by the repeated episodes of upper airway obstruction during sleep, leading to significant hypoxia. Noninvasive evaluation of autonomic nervous system (ANS) and myocardial vulnerability may help determination of OSAS patients who are under high risk of malignant cardiac arrhythmias. The aim(More)
OBJECTIVE To investigate body fat composition, measured by bioelectrical impedance assay (BIA), for predicting the presence and severity of obstructive sleep apnea-hypopnea syndrome (OSAHS). Body fat composition was also compared with other well-known OSAHS predictors such as body mass index (BMI), neck circumference, and abdominal visceral fat. STUDY(More)
AIM P-wave dispersion (Pd) has been reported to be associated with inhomogeneous and discontinuous propagation of sinus impulses. The purpose of this study was to investigate Pd in patients with obstructive sleep apnea (OSA) and to determine its relationship with severity of the disease. METHODS The study population included 67 patients referred to sleep(More)
Neuropsychological deficits are among the main symptoms of obstructive sleep apnea syndrome (OSAS), which could be related to impaired cerebral blood flow (CBF). We conducted a study in 20 subjects tested in our Sleep Laboratory, to assess regional CBF and cognitive function in OSAS. Our measurements included technetium-99m hexamethylamino propylenamine(More)
BACKGROUND Bronchiectasis is described as destruction and the irreversible dilatation of bronchial structure. We wanted to demonstrate our surgical practice and outcome of surgical treatment in bronchiectasis. METHODS We studied records of 60 pediatric patients who underwent surgical resection in our clinic between January 2000 and January 2013. The(More)
