OBJECTIVE The purpose of the present prospective study was to obtain normative data for Equitest computerized dynamic posturography (CDP) in children and young adults and to observe the balance maturation process. METHODS Equilibrium pattern and SOT of 195 healthy children aged from 6 to 14 years were compared to those of 64 young adults aged 20 years,(More)
The effect of a visual and of an auditory task on the cochlea was studied by transiently evoked otoacoustic emissions (TEOAEs). TEOAE amplitude decreased during visual and auditory attention for all 13 subjects tested. The decreased TEOAE activity was noted predominantly within the 960 to 1920 Hz range during visual attention and within the 1920-2880 Hz(More)
OBJECTIVE To compare the efficiency of diffusion-weighted MR imaging (MRI) vs. high resolution CT in predicting recurrent or residual cholesteatoma in children who underwent prior middle ear surgery. DESIGN Prospective study. SETTING Tertiary care university hospital. PATIENTS Seventeen patients (4 with 2 recurrences) aged 5-17 years (mean 11.4)(More)
OBJECTIVES To report the efficacy of propranolol as first-line treatment of head and neck hemangiomas in children and to present an optimized protocol for treating hemangiomas. DESIGN Multi-institutional retrospective study. SETTING Two tertiary care referral pediatric centers. PATIENTS Thirty-nine children with head and neck infantile hemangiomas(More)
OBJECTIVE To assess cidofovir plasma concentration after intralesional airway administration for recurrent respiratory papillomatosis. DESIGN Prospective study. SETTING Tertiary care teaching hospital. PATIENTS AND METHOD The study comprised 21 patients (10 children and 11 adults). Plasma samples were collected at 10 and 45 minutes (T10, T45) or at 10(More)
The effect of a visual task on the active micromechanical properties of the cochlea studied by the evoked otoacoustic emissions (EOAEs) has been the subject of only one published study (Brain Research, 44 (1988) 380-383). In order to examine the reliability of this effect, a similar study has been run on 16 subjects. A significant decrease in EOAEs during a(More)
OBJECTIVE To evaluate the efficacy of cidofovir intralesional therapy in recurrent respiratory papillomatosis and the role of surgical excision as an associated treatment. STUDY DESIGN Prospective study and case series. METHOD Twenty-six patients received intralesional cidofovir. Three endoscopies were performed at monthly intervals, with intralesion(More)
OBJECTIVE The purpose of the present study was to compare equilibrium pattern in 12-year-old children with 20-year-old young adults and to obtain normative data for the BQ in both groups. METHODS Mean stability percentages and synthesis ratios of 29 healthy children aged 12 years were compared to those of 68 young adults aged 20 years, using BQ. RESULTS(More)
In this paper the effect of sleep on the cochlea is studied by transiently evoked otoacoustic emissions (TEOAEs). Amplitude increases considerably (e.g., 4 dB) and the effect of a contralateral noise on the TEOAEs decreases during the night. These modifications can be related to sleep, although there is no link to electroencephalographic sleep stage. During(More)
OBJECTIVES To evaluate hyaluronic acid fat graft myringoplasty (HAFGM) for different tympanic membrane perforation (TMP) sizes and to compare its success rate with that of the underlay and overlay techniques. DESIGN Prospective study. SETTING Tertiary care pediatric center. PATIENTS Two hundred eight children aged 4 to 16 years (mean age, 11.84 years)(More)
