the aim of the current study is to investigate hearing function in patients with allergic rhinitis. fifty-eight patients with positive skin prick test (group 1) (116 ears) and    31 subjects with negative skin prick test (62 ears) as group 2 were included. pure tone audiometry at 250,500, 1000, 2000, 4000 and 8000 hz and immittance measures, including tympanometry and acoustic reflex tests, wer...

Fear-potentiated startle (FPS) is an increasingly popular psychophysiological method for the objective assessment of fear and anxiety. Studies applying this method often elicit the startle reflex with loud white-noise stimuli. Such intense stimuli may, however, alter psychological processes of interest by creating unintended emotional or attentional artifacts. Additionally, loud acoustic probes...

SUMMARY Hearing Disorders have been common diseases. They develop complications such as hearing loss and psycho-social contact problems and would affect children learning process if not properly treated. Malocclusions are included as cause factors of such disorders. The existence and/or extent of interrelations between malooclusions and hearing disorders is a subject of controversy. A case-co...

Audiologic assessment of infants and young children can be confounded by neurologic disorders or neuromaturational delays. In some cases, this results in an inability to assess hearing sensitivity by behavioral measures or by auditory evoked potentials. This case illustrates such an audiologic challenge. Subject DF was born with hydrocephaly, which was treated with repeated shunt surgeries and ...

UNLABELLED The auditory sensitization, a tool used in the investigation of acoustic reflex, allows the decrease of acoustic reflex thresholds from a facilitating stimulus. It may be presented before or simultaneously with the elicitor tone. The thresholds after and before the facilitating stimulus are compared and it is expected to see the decreased threshold. From the study of the acoustic ref...

The time course of the impedance changes caused by the contralateral acoustic reflex was investigated in five normal hearing, young adult subjects The acoustic reflex function was measured with equipment having a time constant of 15 milliseconds which permitted precise temporal measures. Temporal intervals from signal onset and termination to various portions of the acoustic reflex function wer...

We carried out electroneuromyography of 78 patients with degenerative-dystrophic cervical and lumbar spine disorders, which were treated at the neurosurgical department Irkutsk Scientific Centre Surgery Traumatology. The results study late ENMG phenomena such as H-reflex, F-waves A-reflex obtained different stages disease using “Neuromyan” neuromyoanalyzer. predictable changes in answers proces...

conclusions the assr can accurately predict the degree and configuration of hearing loss and discriminate the normal hearing from mild or moderate hearing loss and mild from moderate hearing loss, except for 500 hz. the air-conducted assr could not define the type of hearing loss. results the assr accurately estimates the behavioral thresholds as well as flat and sloping configurations. there w...
