The differentiation of a peritonsillar abscess from peritonsillar cellulitis, although difficult on physical examination, is required in order to determine the appropriate treatment. Peritonsillar cellulitis can be treated with antibiotics alone, while a peritonsillar abscess should be drained. Computed tomography (CT) of the neck is often performed to(More)
OBJECTIVE Gait initiation is a transient procedure between orthostatic posture and steady-state locomotion and includes anticipatory anteroposterior (AP) and lateral movements. Commands for this task are located in some levels of brain stem, which modulates activity of central pattern generator in the spinal cord. The purpose of this work was to explore the(More)
Vestibular evoked myogenic potentials (VEMP) occurring after click stimulation in cervical muscles are thought to be a polysynaptic response of otolith-vestibular nerve origin. In optokinetic after-nystagmus (OKAN) the direction of after-nystagmus changes and slow-phase velocity decreases with head tilt. This phenomenon may be an otolith response to the(More)
In this paper, we propose a new artificial bandwidth extension technique for telephone speech. Usually, the high frequency components of telephone speech are lost due to band limitation. The proposed method produces the high frequency components by estimating the spectral envelope of voiced speech and by restoring voiceless consonant spectrum. Objective(More)
The paper deals with the alterations in the size and functions of the endocrine glands in relation to the reproductive and the seasonal sexual activity of the male hedgehog. Results show that the seasonal variations in body weight, testis, adrenal and the thyroid follow the general pattern of most of the hibernating mammals. Histometric measurements of the(More)
A 9-year-old boy with inner ear malformation complained of slight deafness and unsteadiness. CT revealed a normal cochlea despite enlargement of the lateral semicircular canals. The vertical semicircular canals developed more or less normally. The caloric test showed complete canal paresis bilaterally; however, a horizontal rotational stimulus elicited a(More)
