Comparation of low-temperature plasm radiofrequency and high-intensity focused ultrasound therapy on allergic rhinitis patients with nasal septal deviation / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To compare the therapeutic effects of low-temperature plasm radiofrequency and high-intensity focused ultrasound in treatment of perennial allergic rhinitis (PAR) complicated with nasal septum deviation.@*METHOD@#A total of 224 cases of identified PAR who treated in our hospital were randomly divided into 2 matched groups: low-temperature plasm radiofrequency group (n = 140) and high-intensity focused ultrasound group (n = 84). The therapeutic affection were evaluated by clinical symptoms controlled counting-scores. Inferior turbinate mucosa were collected and examined pathologically before and at 15 days and 6 months after the therapy.@*RESULT@#The follow-up data indicated the effective rate in 15 days was 97.1% in high-intensity focused ultrasound group, and 90.4% in low-temperature plasm radiofrequency group, in 6 months was 90.7% and 85.4% respectively.@*CONCLUSION@#The treatment of high-intensity focused ultrasound in PAR is minimally invasive and safe with reliable efficacy.

The Hearing Status and the Functions of Efferent System in Autistic Children / 听力学及言语疾病杂志

Objective To assess hearing and efferent system functions of autistic children.Methods Tests were performed on 30 Autistic children and 15 normal children to evaluate hearing objectively by using otoacoustic emission (OAE) and auditory brainstem response (ABR).The efferent system functions were analyzed through contralateral suppression in OAE.Results The mean ABR Ⅰ-Ⅴ interpeak latencies (IPLs) in children with Autism were significantly reduced than that in the control group.The amplitudes of OAE at 1 kHz and 2 kHz in autistic children were significantly different in two groups.There were no significant differences in contralateral suppressions between the Autistic children and the control.Conclusion Hearing impairment may be more common in children with Autism than in normal children,while for a few Autistic children,their efferent system functions are affected.
