摘要：Objective: To determine the relationship between the virus burden in infancy a nd hearing loss in congenital CMV infection. Study design: A cohort of 76 infant s with congenital cytomegalovirus (CMV) infection identified by means of newborn virologic screening was monitored for outcome. The amount of infectious CMV was analyzed in urine specimens obtained during early infancy. Peripheral blood (PB ) samples obtained during early infancy were available from 75 children and CMV DNA was quantitated with a real-time quantitative polymerase chain reaction. Re sults: Infants with clinical abnormalities at birth (symptomatic congenital CMV infection) had higher amounts of CMV in urine (P =. 005) and CMV DNA in PB (P =. 001) than infants with no symptoms. Eight children with and 4 children without symptoms had hearing loss. Among children without symptoms, those with hearing l oss had a significantly greater amount of CMV in urine (P =. 03) and PB virus bu rden (P =. 02) during infancy than those with normal hearing. Infants with < 5 ×103 pfu/mL of urine CMV and infants with < 1 ×104 copies/mL of viral DNA in P B were at a lower risk for hearing loss. Conclusion: In children with asymptomat ic congenital CMV infection, hearing loss was associated with increased amounts of urine CMV and PB CMV DNA during early infancy.

摘要：失聪并不是老年人的专利,因为各种各样的原因,青年人,甚至孩子也有可能失聪,而且很多是突发性失聪。如果早上起来突然听不见了,应该怎么办呢?孩子也可能突然失聪一名9岁的男孩突然自觉听力严重下降,耳朵好像塞满了东西,听不清声音,并伴有眩晕、恶心欲呕等症状。经检查后,医生确诊男孩患的是突发性耳聋,患病的原因与其学习压力较大、精神过于紧张有关。

摘要：突发性耳聋患者长期处于高度紧张的状态,自身无法妥善处理。如果这种紧张状态远远高于人们正常的心理承受能力,突发性耳聋患者的心理就会严重失衡。突发性耳聋,简称"突发性聋"或"突聋",是指未知原因引起的感音神经性听力丧失的突然发作。听力损失可能会在数分钟,数小时或1至2天之内发生,甚至发展成严重的耳聋。

摘要：汉语声调具有重要的区别字义的功能,模式言语助听装置正是为极重度聋人感知高频辅音和基频信息而设计。本文就模式言语助听下的汉语普通话声调识别进行系统测试。结果发现,听力正常者在自然语音无听力放大条件下和在模式言语助听下,其声调错误识别率无显著差异。说明模式言语提供的正弦化基频信息可为听力正常者感知成声调信息。极重度聋人在模式言语助听下声调错误识别率较在传统助听下有显著降低,说明模式言语助听能为极重度聋人提供更易分辨的声调信息,有助于提高他(她)们的看话能力,是其实现听力语言康复的有效手段之一。
