Study of auditory function in patients with chronic obstructive pulmonary diseases

Study of auditory function in children with chronic lung diseases

“…However, TEOAEs results had a statistical significant difference between hypoxemic and non-hypoxemic cases especially at frequency of 2.0 kHz; with a significant positive correlation between PaO 2 levels and otoacoustic emissions thresholds. These came in agreement with many studies [13,28,29].…”

“…Lower echo levels were observed in the studied patients in comparison to control group. This was concomitant with study of El-Kady et al [13] that showed marked decrease in the magnitude of both otoacoustic emissions and the cochlear potentials under hypoxia. The differences in echo levels between studied patients and the control group reached high statistical [ ( ) T D $ F I G ] significance level at the higher frequencies.…”

“…In contrary to, El-Kady et al [13] current audiometry and tympanometry results showed no statistical significant difference between patients had hypoxemia and those non-hypoxemic. However, TEOAEs results had a statistical significant difference between hypoxemic and non-hypoxemic cases especially at frequency of 2.0 kHz; with a significant positive correlation between PaO 2 levels and otoacoustic emissions thresholds.…”

“…The transduction mechanism of the inner ear is highly dependent upon the cochlear oxygen supply. In addition, many studies showed marked decrease in the magnitude of both distortion product otoacoustic emission and the cochlear potential under chronic hypoxia [12,13]. Ototoxicity is due to drugs or T.L.C., total leucocytes count; C.B.G., capillary blood gases.…”

Changes in Balance after Rehabilitation Program in Patients with COPD and in Healthy Subjects

“…The underlying mechanisms for the increased postural sway observed in people with COPD are currently unknown. Although vestibular deficits are unlikely [39,40], somato sensory deficits could contribute to impaired balance in this population [41].…”
