ABSTRACT
OBJECTIVE To evaluate the difference of efficacy of sublingual immunotherapy on different age patients with allergic rhinitis. METHODS 229 patients with dermatophagoides farina drops allergic rhinitis who have finished SLIT at least 2 years were enrolled and analyzed by retrospective analysis. All patients were divided into different age groups: pre-adolescence(n=107), adolescence(n=53), adulthood(n=69). Indexes for therapeutic effects of SLIT visual analogue scale(VAS) score, rhinitis symptom scores, medication scoreintra- and inter groups were assessed during different stage of treatment(3 months, 1 year and 2 years). Data were analyzed with SPSS 19.0 software. RESULTS Compared with prior treatment, after the SLIT for 3 months, 1 year, 2 years, VAS scores, rhinitis symptom scores, medication scoresof all the patients with allergic rhinitis are significantly decreased; Differences of rhinitis symptom scores(H=0.844, 4.153, 2.669, P>0.05), VAS score(H=1.356, 3.720, 0.313, P >0.05), medication scores(H=1.044, 5.841, 3.399, P>0.05) between groups had no statistical significance at different stage after treatment(3 months, 1 year and 2 years); The differences between 2 years and 1 year of SLIT treatment showed statistical significance in the VAS scores(Z=1.635, P =1.635). CONCLUSION SLIT with dust mites drops had good curative effect and security in patients with allergic rhinitis, which hadno obvious difference between different age groups.
ABSTRACT
OBJECTIVE To determine the distribution of allergens in patients with allergic rhinitis in Wenzhou area. METHODS Patients with AR symptoms from January 2013 to December 2014 were given skin prick test (SPT). The clinical data about SPT was retrospectively colleceted to analyze SPT results. RESULTS 1. Among 2991 individuals, the total positive rate of SPT was 82.0%, with Dermatophagoides farinae (Der. f) and Dermatophagoides pteronyssinus (Der.p) as the most common allergens; the positive rate of inhalant allergen was obviously higher than that of ingestive ones, with significantly statistical difference(χ2=2006.557,P<0.01). Most of patients were allergic to double allergens; the intensity of Der.f and Der.p mainly presented as (++++), with no significant difference(Z=-0.391, P=0.696). 2. There was significant difference of variation with seasons(χ2=34.254, P<0.01). 3. No significant difference of positive rate were observed in different AR-courses(χ2=16.102, P<0.01). 4. Significant difference of positive rate was found among different age-groups; The positive rate was increased along with growing age, got peak at group of 10-12 years old, and then got down after that. CONCLUSION Dust mite was the main allergen coursed AR in Wenzhou area. Seasons and age were two important factors effecting on positive of SPT and onset of AR. The positive rate of allergens was related to age.
ABSTRACT
Objective To evaluate the effects of different treatments to middle turbinate by endo-scopic sinus surgery (ESS) on olfaction in patients with chronic sinusitis and nasal polyps. Methods ESS was performed on 74 cases of chronic sinusitis and nasal polyps. Proper treatments divided into the group of retaining middle turbinate, the group of forming middle turbinate and the group of partial endonasal middle turbinectomy which were applied to different pathological changes of middle turbinates. The olfactory function of the 74 patients was tested through the CCCRC olfactory testing method pre-operation and twenty-four weeks post-operation. The results were analyzed by analysis of variance. Results The olfaction after treat-ment of the three groups was significantly better than that of pre-operation (P < 0.05), but there was no sig-nificant difference among the three groups (P>0.05). Conclusion Different treatments to middle turbinate by ESS is no obvious effects on olfaction.
ABSTRACT
Objective To study the expressions of TGF-?1 and p21WAF1 in middle ear cholesteatoma and discuses their effects on cholesteatoma.Methods The expressions of TGF-?1 and p21WAF1 were determined by immunohistochemical S-P technology and computer image analysis in 20 specimens of cholesteatoma epithelium and 10 specimens of normal external canal skin.Results ① p21WAF1 and TGF-?1 could be detected in middle ear cholesteatoma and in normal ear canal skin.p21WAF1 was located at karyon,taking on yellow-brown pellet;TGF-?1 was located at cytoplasmic,taking on yellow-brown pellet.②The p21WAF1 positive rate in middle ear cholesteatoma was 65%;and there were almost no positive cells in normal external ear canal skin.p21WAF1 positive cells were detected in each layers,its LI was 28.9%?6.7%.Compared with normal ear canal skin,the expression level of p21WAF1 in middle ear cholesteatoma epithelium was higher than that in normal ear canal skin(P
ABSTRACT
OBJECTIVE To investigate the continuous expression of keratinocyte growth factor(KGF)and keratinocyte growth factor receptor(KGFR)in external auditory canal skin adjacent to tympanic membrane perforation and analyze the role of KGF and KGFR in the different turnover of chronic otitis media.METHODS The external auditory canal skin adjacent to tympanic membrane perforation from 20 cases with cholesteatoma otitis media and the corresponding cholesteatoma tissue and normal external ear skin were examined by immunohistochemical S-P method and quantitative analysis.The positive rate was compared with 20 cases of non-cholesteatom otitis media's external auditory canal skin adjacent to tympanic membrane perforation.RESULTS The staining for KGF and KGFR in cholesteatoma otitis media's external auditory canal skin adjacent to tympanic membrane perforation was consistently stronger than that in non-cholesteatoma otitis media.The positive rates of the two tissue was(33.135?6.364)% and(19.965?10.570)%,(19.380?2.827)% and(13.145?7.935)% respectively,revealing a significant difference.CONCLUSION The activity of hyperproliferation of the external auditory canal skin adjacent to tympanic membrane perforation in cholesteatoma otitis media is stronger than that of non-cholesteatoma otitis media.KGF and KGFR may play a more important role for hyperproliferation of cholesteatoma.
