ABSTRACT
Objective To investigate the correlation between auditory steady-state response (ASSR)and behavioral audiometry threshold in deaf children.Methods A total of 63 cases (126 ears)of severely and profoundly hearing impaired children from 0.5 years to 6 years were divided to Group A of 0.5~1.0 years,Group B of 1.1~3.0 years and Group C of 3.1~6.0 years old.ASSR and behavioral hearing tests were conducted in the sound field. 0.5~1.0 years old children were tested with the behavior observation Audiometry (BOA),1~2 years old children with visual reinforcement audiometry (VRA),while those of 3 ~6 with play audiometry (PA).Results For the ASSR response thresholds and pure tone hearing thresholds at 0.5,1,2 and 4 kHz,the correlation coefficients were 0.75,0.76,0.76,and 0.83,respectively.There was a significant correlation (P <0.01 ).The hearing thresholds were generally lower than the ASSR response thresholds,and with increasing frequency,the gaps were narrowed between the two.For Group A at each frequency the response thresholds and behavioral audiometry correlations were lower than those of Group B and C with the lowest at 0.5 kHz.Conclusion For the children of 0.5~6 years, ASSR and behavioral audiometric thresholds have good correlations.ASSR can provide information about the behav-ior thresholds for young children and those high risk children and for fitting hearing aids.
ABSTRACT
OBJECTIVE@#To discuss the clinical characteristics and early diagnosis and treatment of relapsing polychondritis(RP).@*METHOD@#Twenty-six RP patients received the therapies of antibiotics, glucocorticosteroid, immunosuppressive agent,tracheotomy, tracheal sent implantation or non-invasive ventilation.@*RESULT@#Twenty-six cases (88.5%) had auricle involvement, 20 cases (76.9%) had respiratory tract involvement, 18 cases (69.2%) had joints involvement, 10 cases (38.5%) had nose involvement, 6 cases (23.1%) had eyes involvement, 4 cases (15.4%) had cochlea and (or) vestibular involvement. Some patients with cardiac, vascular, kidney damage as well. One case died of severe pulmonary infection. One case died of respiratory failure. The symptoms of other 24 cases were stable or improved in different degrees.@*CONCLUSION@#The clinical manifestations are diverse in RP patients, mainly in department of Otolaryngology, the prognoses of patients with airway involvement are worse, and it may improve the curative effect by an early diagnosis and a timely treatment.
