OBJECTIVE In this study, our aim was to determine presence of dysfunction in the efferent auditory system of children with type-I diabetes mellitus (DM) presenting no evidence of symptomatic neuropathy. METHODS Thirty children with type-I DM (DM group) and 31 age matched healthy children (control group) with normal hearing and middle ear function were(More)
OBJECTIVES To assess regrowth potential of the tonsils following partial tonsillectomy performed by using radiofrequency. METHODS Follow-up results of 42 children (aged from 1 to 10 years) who consecutively had partial tonsillectomy with radiofrequency due to obstructive sleep apnea or snoring were evaluated for regrowth of the tonsils. RESULTS Regrowth(More)
OBJECTIVE Serotonergic neurons innervating motoneurons increase their firing rates in response to respiratory challenges, and long-term facilitation of respiratory activity in response to hypoxia is serotonin (5-HT) dependent. Polymorphism of the genes which code for 5-HT receptors may affect functions of the serotonergic system, and may be associated with(More)
Obstructive sleep apnea syndrome (OSAS) is a common sleep disorder and related to multiple conditions that cause mortality in adults. In the present study, reliability of SleepStrip, a disposable screening device for detection of OSAS, is tested. In this prospective, nonrandomized double-blinded single cohort study at an academic health center, the(More)

All were treated medically. We recorded the patients' demographic parameters, systemic diseases, time elapsed between onset of sudden hearing loss and initiation(More)
Dental laboratory technicians may be exposed to metal alloys that are used in the production of crowns, bridges and removable partial dentures. These alloys consist of 35-65% cobalt, 20-30% chromium, 0-30% nickel, and small amounts of molybdenum, silica, beryllium, boron and carbon. The aim of this study was to assess whether dental technicians are(More)
The middle ear of guinea pigs has long been used for experimental studies, but no detailed information about its temporal bone anatomy is available. In 18 adult guinea pigs, the temporal bone, eustachian tube, and inner ear anatomy, in addition to the anatomy of the middle ear, were investigated under the dissection microscope. In addition to properties of(More)
BACKGROUND AND OBJECTIVE Obstructive sleep apnea syndrome (OSAS) is a common condition characterized by repetitive pharyngeal collapse during sleep and daytime sleepiness. There is genetic predisposition to sleep disorders. Serotonin is involved in the regulation of sleep. The synaptic 5-hydroxytryptamine (HT) is inactivated by presynaptic reuptake, which(More)
