Objective To evaluate the efficacy of intratympanic steroid therapy compared with systemic ster‐oid therapy on the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL) patients with damaged glu‐cose tolerance .Methods Fifty first -diagnosed unilateral ISSNHL patients with damaged glucose tolerance were randomized devided equally to the intervention group (intratympanic steroid therapy) or the control group (systemic steroid therapy) ,all patients received conventional drug therapy simultaneously .Pure-tone hearing threshold tests were performed in all patients every 3 days after the first time ,and repeated measures anova was used to assess effects of hearing recovery accompanied with time .Results The mean hearing threshold in the control group de‐creased from 85 .4 ± 5 .6 dB to 48 .2 ± 4 .9 dB ,while in the intervention group it decreased from 84 .8 ± 5 .6 dB to 31 .7 ± 4 .6 dB .Total effective rate in the intervention group (84 .00% ,21/95) was higher than that in the control group (68 .00% ,17/25)(P<0 .05) .Conclusion The intratympanic steroid therapy is more effective than systemic steroid therapy in the treatment of ISSNHL patients with damaged glucose tolerance .

Objective To study the correlation between laryngopharyngeal reflux (LPR) and secretory otitis media (SOM).Methods A total of 294 adult patients with reflux-related symptoms were recruited in this study.The patients were evaluated with reflux symptom index (RSI) and reflux finding score (RFS).Tympanometry was conducted to all the patients.The 54 patients with the otitis media effusion with type B tympanograms were tested by auripuncture.Results Among the 294 patients,168 cases showed RSI＜13,in which 128 cases,31 cases and 9 cases had type A,type C,and type B tympanograms,respectively.The other 126 patients showed RSI＞13 in which 52 cases,29 cases and 45 cases had type A,type C,and type B tympanograms,respectively.Among the 294 patiems,172 patients showed RFS＜7,in which 131,32 and 9 cases had type A,type C,and type B tympanograms,respectively.The left 122 patients showed RFS＞7,in which 49,28 and 45 cases had type A,type C,and type B tympanograms,respectively.The ratio of type B tympanograms in the patients with RSI＞13 and RFS＞7 were both significantly higher than those in the patients with RSI＜13 and RFS＜7 (P＜0.05).The RSI scores of patients with type A,C,and B tympanogram were 8.6± 3.8,15.9±7.5,and 23.9±8.6,respectively,and the RFS score were 5.6±2.6,9.6±4.7,and 15.3±6.6,respectively.Compared with type A and C,the patients with type B tympanogram had significantly higher RSI and RFS score (P＜ 0.05).Among the 54 patients of type B tympanograms,those with RSI＜13 were found to have serous fluid,grume fluid,glue fluid as in 6 cases,2 cases,and 1 case,while the patient of the RSI＞ 13 had serous fluid,grume fluid,glue fluid in 13 cases,23 cases,and 9 cases,respectively.The otitis media effusion of the patients with the RSI＜13 were mainly serous,while those with the RSI＞13 were mainly sticky.Conclusion The correlation between LPR and SOM was significant.LPRmay accelerate the progress of SOM.

Objective:To investigate the value of peripheral blood eosinophils (EOS) in predicting the therapeutic effect of sublingual specific immunotherapy (SLIT) in patients with allergic rhinitis (AR).Methods:From January 2018 to June 2020, 200 patients with AR who received SLIT in Dongguan Kanghua Hospital were evaluated for their symptoms before treatment and 6 months after treatment. The curative effect was evaluated according to the improvement of the total symptom score. The number of eosinophils, percentage of eosinophils in peripheral blood were measured before treatment. The correlation between curative effect and EOS count and EOS percentage was analyzed and the value of these two indicators in predicting the efficacy of SLIT was evaluated.Results:Of the 200 AR patients, 178 patients were confirmed to have completed the treatment course of 6months. 126 effective and 52 ineffective, the effective rates were 70.8%. There was a weak correlation between the number of EOS in peripheral blood and the percentage of EOS in peripheral blood before treatment and the efficacy of SLIT ( r=0.168, P=0.048; r=0.250, P=0.001). The area under the curve of peripheral blood EOS count was 0.380, and the percentage of peripheral blood EOS was 0.355, which were all less than 0.5. Conclusions:There was no significant correlation between the number of peripheral blood EOS count and peripheral blood EOS percentage and the efficacy of SLIT , therefore, both of blood EOS count and blood EOS percentage have no value in predicting the efficacy of SLIT.
