ABSTRACT
Objective@#To investigate the epidemiological characteristics of allergic rhinitis (AR) in Ningxia and to analyze its related factors.@*Methods@#From March to September of 2013, a multi-stage and cluster sampling method was used to investigate the diagnosis and treatment of AR in Ningxia Area (3 years and above). Guidelines for diagnosis and treatment of allergic rhinitis (2009, Wuyishan) was used as the basis for the diagnosis of adult AR, while Guidelines for diagnosis and treatment of pediatric allergic rhinitis (2010, Chongqing) was used as the basis for children. SPSS 16.0 software was used to complete the statistical analysis.@*Results@#The total number of questionnaires was 6 000, and the number of effective questionnaire was 5 236, the recovery rate was 87.27%. With 684 cases diagnosed of AR, the prevalence of AR in Ningxia was 13.06% (684/5 236), including 13.40% (325/2 425) of males, 12.77% (359/2 811) of females. The difference was not statistically significant (χ2=0.456, P>0.05). There was significant difference in the prevalence between Hui and Han [14.35% (452/3 150) vs 11.12% (232/2 086), χ2=11.51, P<0.05]. According to ARIA criteria, persistent AR was 27.63% (189/684), intermittent AR was 72.37% (495/684). The month with highest incidence of AR in Ningxia Area was September, accounting for 71.78% (491/684). The prevalence of urban population was 14.54%, with the prevalence of rural population was 11.90%, and the difference was significant between urban and rural residents (χ2=7.90, P<0.05). The age group with highest prevalence rate was 21~30 years old. The main inhalation allergens were mugwort (68.42%), weeds (58.48%) and ragweed (55.56%). The main dietary allergens were wheat flour (14.33%), peanut (13.74%) and walnut kernel (11.99%). The most common complication was allergic conjunctivitis [82.02% (561/684)].@*Conclusion@#The epidemiology of AR in Ningxia Area is preliminarily understood, which will provide the epidemiological evidence for the prevention and treatment of AR and the formulation of public health policy.
ABSTRACT
Objective:To observe the outward flow of low temperature plasma ablation combined inferior turbinate fracture treatment for chronic hypertrophic rhinitis nasal ventilation function. Method:NR6 nasal resistance meter and A1 nasal sound reflection instrument were used to test 40 patients of Hypertrophic rhinitis nasal septum deviation merger before and after operation for one year, recording the nasal airway resistance,0 to 5 cm nasal cavity volume and the nasal minimum cross-sectional area, combine visual analog scale to analyze the changing parameter value, and to analyze the test values between the correlation. Result:Postoperative patients of NCV, NMCA, NS value was higher than that of preoperative, VAS, NAR value compared with preoperative lower (P<0.05); Postoperative VAS was negatively correlated with NCV, NMCA, NS (r=0.472, 0.698, 0.586, P<0.05); VAS was positively related with NAR (r=0.877, P<0.05); Postoperative NAR was negatively correlated with NCV, NMCA and NS (r=-0.464, -0.870, -0.707, P<0.05); there was a positive correlation between postoperative NS and NCV, NMCA (r=0.442, 0.741, P<0.05). Conclusion:On the deflection of nasal septum (lighter, smaller scale, the part of the deflection of a back with no obvious compressive deformation and lateral deflection of inferior turbinate) in patients with chronic hypertrophic rhinitis, low temperature plasma ablation combined offshoring inferior turbinate fracture surgery can effectively improve the nasal ventilation function, there is a good correlation between postoperative test values.
ABSTRACT
OBJECTIVE@#To investigate the epidemic features of childhood allergic rhinitis (AR) and correlative risk factors in Yinchuan.@*METHOD@#A questionnaire survey on AR was conducted among 800 children in eight communities, aged from 5 to 14 years old, by random cluster sampling, from March 2012 to March 2013 in Yinchuan. Suspects of AR, as identified by the survey, were recommended to specialist examinations for accurate diagnosis. The results were statistically analyzed.@*RESULT@#Seven hundred and sixteen questionnaires were returned and 662 questionnaires were available. The prevalence rate of AR in children aged from 5 to 14 is 14.65% in Yinchuan. Seventy-nine point thirty-eight percent children suffered from intermittent AR, while 20.61% children suffered from persistent AR. The difference of prevalence between female (13.57%) and male (15.44%) was insignificant statistically (Χ2=0.454, P>0.05). The difference of prevalence between the Han (15.72%) and the Hui (11.35%) insignificant statistically (Χ2=2.055, P>0.05). The prevalence of AR children aged five to nine years was 13.80%, as aged ten to fourteen years was 19.72%. There was a significante differece between two groups (Χ2=4.056, P<0.05). The most explosive outbreak month in children with allergic rhinitis was July to September. The most common allergens found in patients were seasonal plants: mugwort, weed, dandelion, cereal, locust, ragweed, and willow. Fifteen point forty-six percent patients with AR also had rhinitic, 14.43% patients had asthma and 14.43% patients had allergic conjunctivitis. The history of drug allergy accounted for 12.37% in patients with AR, and food allergy accounted for 26.80%. In allergic rhinitis risk factors, family history accounted for 30.92%, non-breastfeeding representing accounted for 34.02%, animal feeding history accounted for 19.59%; exposure to passive smoking accounted for 42.26%; domestic decoration accounted for 12.37%. There were significante difference between AR children and normal in family history and non-breastfeeding (P<0.05).@*CONCLUSION@#The prevalence rate of AR in children aged from 5 to 14 in Yinchuan is 14.45%. Strategy of prevention and treatment of AR should be worked out according to the epidemic feature of AR.
