Hearing loss (HL) was prospectively studied in 236 children with meningitis using brainstem auditory evoked responses. Hearing loss was detected in 38 (16.1%) in the acute phase of the disease and in 10 (5.2%) of 193 patients who were tested 6 months later. Hearing loss was more frequent and more severe in patients with bacterial meningitis (25.4% in the(More)
Hearing loss was studied prospectively using auditory brainstem potentials in 34 children with Hemophilus influenzae meningitis treated with chloramphenicol and in 36 children with purulent meningitis caused by microorganisms other than H influenzae treated with ampicillin. Our results indicate that high doses of ampicillin are not associated with permanent(More)
Recovery patterns after unilateral labyrinthectomy were studied using a torsion pendulum to produce angular accelerations in unanaesthetized, immovilized cats. The oculomotor activity before and during angular accelerations was recorded and cuantified in 10 post-labyrinthectomized cats during 26 days of recovery both with and without environmental fixation(More)
The middle-ear air-spaces (MEAS) not only act as an air reservoir and provide a buffering effect against negative intratympanic pressures caused by tubal dysfunction, but more fundamentally constitute a resonant cavity whose impedance is appropriately tuned to the frequency response of the auditory system of each individual species. When this ideal air(More)
