今天是"国际爱耳日":你的听力可还好?

2016-03-03 朱翠云编译 公共卫生信息

全球5%的人口(约3亿6千万人)伴有聋度为残疾的听力损失,其中逾 3千2百万为儿童,主要分布在中低收入国家。 听觉在儿童学习语言、掌握知识和融入社会中都发挥着至关重要的作用。听力损失的儿童在接受教育和社会交往方面均存在困难,因此,如能早期诊断并给予适当的干预,对其将大有裨益。 据世卫组织估算,

已有实验证明:戴耳机连续听1小时音乐,听力明显下降,连听2小时,真的会对听力造成不可恢复的伤害!爱惜自己的听力,采取行动,刻不容缓!

全球5%的人口(约3亿6千万人)伴有聋度为残疾的听力损失,其中逾 3千2百万为儿童,主要分布在中低收入国家。
 
听觉在儿童学习语言、掌握知识和融入社会中都发挥着至关重要的作用。听力损失的儿童在接受教育和社会交往方面均存在困难,因此,如能早期诊断并给予适当的干预,对其将大有裨益。
 
据世卫组织估算,约有60%儿童的听力损失是可以避免的。如果听力损失不可避免,则需要通过听力重建、教育和赋权等措施协助患儿充分开发潜能。为实现这一目标,需要双方共同努力、采取行动。
 
儿童听力损失的成因?
听力损失有多种成因,包括先天因素和获得性因素,前者指出生时或出生不久即出现的先天性听力损失,后者指儿童时期出现的听力损失。听力损失可能是多种因素共同作用的结果,但有时难以查明确切成因。

儿童听力损失的可能成因包括:
遗传因素:
约40%的儿童听力损失由遗传因素引起。证据表明,近亲结婚或亲缘相近的个体产生的后代发生听力损失的概率更高。由于基因或环境因素导致先天性耳或听神经畸形可能是引起听力损失的原因。
产时因素:包括早产、低出生体重、新生儿窒息1和新生儿黄疸。
感染:母亲怀孕期间感染风疹、巨细胞病毒等可能引起新生儿听力损失,此外脑膜炎、麻疹和流行性腮腺炎等也可能导致听力损失。在低收入国家,慢性化脓性中耳炎等耳部感染非常常见,除引起听力损失外,耳部感染也可能引起致死性并发症。
耳部疾病:耵聍栓塞(耳垢堆积)及耳道积水引起的咽鼓管堵塞(非化脓性中耳炎)等常见耳部疾病也可以引起儿童听力损失。
噪声:长时间大音量的使用智能手机、MP3等个人音频播放设备可能引起听力 损失。烟火爆竹等短时间高分贝的噪声可能会引起永久性听力损失。此外,新生儿重症监护病房的设备噪声也能够引起听力损失。
药物: 用于治疗新生儿感染、疟疾、耐药结核及癌症等多种药物,因其具有耳毒性,均可导致听力损失。在很多地区,尤其是存在药物应用不规范的区域,耳毒性药物经常被用于治疗儿童常见感染。
  
预防和护理策略有哪些?

必须采取措施以减少听力损失发病率,并改善其预后。政府、公共卫生机构、社会服务组织、教育机构和民间社会团体应群策群力,共同促进听力损失的防控工作。
加强孕产妇和儿童卫生保健 规 划,包 括 开展免疫接种和建立听力损失患者的组织;
实施婴幼儿和学校听力筛查规划;
培训听力保健方面的卫生专业人员;
提供听力设备和各种交流法;
监管和监测耳毒性药物的使用情况和环境噪声水平;
增强公众意识保护听力和减少耻辱感。

JCI:新型抗生素有望不再损伤听力

链霉素、庆大霉素等的氨基糖甙类药物是一类常用的抗生素,在一些必要的情况下,使用这些药物能挽救很多生命,但它们也带来了明显的副作用,其中最突出的就是对听力和肾功能的损伤。时至今日,因为使用这些药物而造成失聪的情况依然时有发生,这也极大地限制了这类药物的应用。 不过,最近一项来自斯坦福大学医学院的研究成果带来了改善这一现状的新希望:研究者们改良了药物的化学结构,成功地在动物实验中避免了失聪和肾损伤的

世界卫生组织:技术转让有助听力

“舒耳艺听力”加拿大创始人霍华德?温斯坦开玩笑说:“有四种助听器在发展中国家有售:BTE、ITE、ITC和ITD。”舒耳艺听力提供低成本数字助听器。对助听器使用者而言,前三组缩略词应该比较熟悉(分别是“耳背式”、“耳内式”和“耳道式”助听器)。但按照温斯坦的说法,发展中国家的人们最终拥有的都是最后一种类型:放抽屉里不用式助听器。温斯坦解释说:“在发展中国家,幸运地拥有助听器的人往往得不到电池,

NEJM:缬更昔洛韦用于治疗先天性巨细胞病毒病

背景通过静脉注射更昔洛韦治疗并使用6周用于治疗先天性巨细胞病毒病,6个月内可以提高患者听力,但是,随着时间的推移药物提高听力的效果日益减退。方式我们做了一个随机、以安慰剂对照缬更昔洛韦治疗的实验,研究对象是已出现临床症状的先天性巨细胞病毒病(CMV)的新生儿。通过使用缬更昔洛韦或安慰剂治疗6周或6个月,并比较用药治疗效果。我们观察的主要指标是观察患者6个月来听力较好的耳朵从原始听力至治疗后的变化,

JAMA子刊:耳蜗血液循环减弱会使民众患老年性耳聋

背景随着年龄的增加,人们并不知道人类颞骨耳蜗血管壁的厚度变化。 目的该研究的目的是比较螺旋动脉和血管纹毛细血管厚度,并探究是否发生老年性耳聋与颞骨血管纹萎缩和血流量减少的关系。设计该研究为回顾性病例对照研究,研究人员选取了明尼苏达大学采集的共1024例尸检报告。所选取的病例皆为60岁以上且发生感音神经性听力减退并逐渐加重的患者(实验组)。对照组患者未发生听力减退。所有患者都接受过纯音测试检查。参与

赖床坏处多 还损害记忆力和听力

充足的睡眠可解除疲劳、恢复精力。然而早上赖在床上不起,使睡眠时间超过需要。这种不良习惯,长此以往,会有损身体健康。有关测定表明,空气中含有大量细菌、二氧化碳气体以及灰尘等,容易损害呼吸系统,诱发感冒、咽喉炎,还可以引起咳嗽、头昏脑胀等。 赖床危害逐个数: 1、赖床损害呼吸系统 经相关医学专家研究发现,告知我们,清晨卧室内空气比较混浊,有关测定表明,空气中含有大量细菌、二氧化碳气体以及灰尘等,

NEJM:以耳部症状为首发的利什曼原虫病

一名82岁的男患者来院就诊,称其左耳出现肿胀并伴有听力障碍,已有1年余。他曾自行应用糖皮质激素局部外敷耳部4个多月,今因症状没有减轻而来就诊。经体格检查可见,其左耳呈肿胀样,伴有硬结和红斑的症状(图A所示),但没有出现周围淋巴结肿大的迹象。取局部组织活检显示真皮内慢性炎性浸润,淋巴细胞融合性上皮样肉芽肿。高倍镜下可见真皮巨噬细胞(图B所示)胞浆内含有丰富的无鞭毛体。经过聚合酶链反应测定和病原体培养
