  • 简介:目的了解幼儿耳部疾病情况,为制定幼儿人群听力损失的防治策略提供科学依据。方法用横断面现场调查法对句容幼儿园在园幼儿进行耳部疾病的问卷调查及耳科检查。数据采用SPSS15.0统计软件进行处理。结果共调查2.5—7岁幼儿9348人,男性4819人(51.56%)、女性4528人(48.44%)。所调查幼儿的耳部疾病患病率为4.14%,各年龄段差异有统计学意义(P〈0.05),但男性(4.19%)与女性(4.08%)幼儿耳部疾病患病率差异无统计学意义(P〉0.75)。患中耳炎242人,占耳部疾病患者的62.50%。Logistic多元回归结果显示,分泌性中耳炎、年龄、耵聍栓塞、急性中耳炎、慢性化脓性中耳炎、遗传性家族史、早产及低体重、新生儿窒息均与耳部疾病相关。结论目前幼儿人群中,耳部疾病的患病率仍较高,定期体格检查的项目中宜包括耳鼻咽喉科内容,积极制定预防幼儿耳部疾病及听力损失的策略和方案很有必要。

  • 简介:目的调查报告安徽省六安眼外伤病人的流行病学状况及治疗效果.方法对280例(289眼)眼外伤住院病人进行回顾性分析,分析眼外伤病人流行病学状况、治疗效果,有针对性的做好防治工作.结果目前,六安眼外伤病人仍以穿通伤为主,约占60%,并逐年增加,年龄分布以儿童及青少年为主.职业以农民、儿童、学生为主.治疗效果较以往明显提高,其中暴力伤的治疗效果差,最终视力预后与是否伴有黄斑部损害及视网膜脱离有关,与入院时视力无关.结论B超、CT、MRI等辅助检查应用,显微手术、玻璃体手术,及时的药物治疗是决定最终治疗效果的关键.安全教育、医疗保险制度、防护镜使用是减少眼外伤的发病率并提高眼外伤最终治疗效果的主要因素.
