How weak bones can trigger sudden deafness: Having osteoporosis 'doubles the risk', study warns 

　　研究人员表示：患有骨质疏松妇女的脸几乎双重发展突发性耳聋的风险与那些没有骨疾病相比。他们相信的基本过程，导致迅速变薄的骨头也影响身体其他系统。

　　突发性感音神经性听力损失(SSHL)，也被称为突发性耳聋，是一种原因不明的，听，一只耳朵通常发生的快速流失。它可以一次或超过数天的过程中发生的。在这声音逐渐低沉或减少。大约有一半的人会自发地恢复他们的听力发展的突发性聋的人，但它是立即寻求治疗类固醇药物的重要可以帮助。85%左右的人被视为条件恢复部分听力分，其余的有听力损失，继续恶化。启仁田博士的研究，在奇美医学中心，台湾，说：“越来越多的证据表明，骨质疏松症不仅影响骨骼健康，但心脑血管系统，“我们的研究结果表明，突发性感音神经性聋(SSHL)可以是另一个更广泛的健康问题与骨质疏松症。”

　　共有2300000个50岁以上的女性在英国有骨质疏松症。老年妇女更多的骨质疏松症的风险，因为骨质流失的速度是由更年期加速。至少有两个妇女和50岁以上的五人有患打破由于较差的骨健康的终生风险。每年有89000髋部骨折与骨质疏松症的成本?6000000在英国的健康和社会成本的一天。该研究的医疗记录，10660台湾居民谁被诊断为骨质疏松症的1999和2008之间。这些进行比较，他们31980人没有条件，表示在内分泌协会临床内分泌与代谢杂志报道。利用国家保险记录，研究人员分析了多少参与者被诊断为突发性耳聋与2011年底。那些被诊断为骨质疏松症的有1.76更高的患突发性感音神经性聋组比无骨质疏松的风险。

　　在那些患有骨质疏松症，91例在随访期间的突发性聋。

　　相比之下，对照组，这是三重的大小，有155人被诊断为突发性耳聋。研究人员并不确定什么样的生物学机制是负责的关系。医生说，这是可能的，一些危险因素与疾病包括心血管疾病，骨去矿化作用，炎症和内皮功能障碍可能发挥的一部分。他说：“全世界越来越多的人患有骨质疏松症，和我们的工作表明它们在感音神经性听力损失的风险以及骨折和其他问题。谁有骨质疏松症患者应该意识到他们需要如果他们经验的听力损失，立即寻求医疗帮助。”国家骨质疏松协会(NOS)的慈善机构，其中卡米拉，康沃尔公爵夫人，是总统在看到她的母亲和祖母患上疾病，对疾病的早期诊断活动。

　　Women who suffer osteoporosis face almost double the risk of developing sudden deafness compared with those who do not have the bone disease, say researchers.

　　They believe the underlying processes that lead to rapidly thinning bones are also affecting other systems in the body.Sudden sensorineural hearing loss (SSHL), also called sudden deafness, is an unexplained, rapid loss of hearing that typically happens in one ear.It can happen at once or over the course of several days. during which sound is gradually muffled or reduced.

　　About half of the people who develop SSHL will spontaneously regain their hearing, but it is important to seek treatment immediately as steroid drugs may help.

　　About 85 per cent of those who are treated for the condition recover some hearing, but the remainder have hearing loss that continues to worsen.Study author Dr Kai-Jen Tien, of the Chi Mei Medical Center, Taiwan, said: ‘A growing body of evidence indicates that osteoporosis affects not only bone health, but the cardiovascular and cerebrovascular systems,‘Our findings suggest sudden sensorineural hearing loss (SSHL) can be another broader health problem connected to osteoporosis.’Altogether 2.3 million women over the age of 50 in the UK have osteoporosis. Older women are more at risk of osteoporosis because the rate of bone loss is accelerated by the menopause.

　　At least one in two women and one in five men over the age of 50 have a lifetime risk of suffering a break as a result of poor bone health.

　　Every year there are 89,000 hip fractures linked to osteoporosis which cost the UK ?6 million a day in health and social costs.The study examined medical records for 10,660 Taiwan residents who were diagnosed with osteoporosis between 1999 and 2008.

　　These were compared them to 31,980 people who did not have the condition, says a report in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.

　　Using national insurance records, the researchers analysed how many participants were diagnosed with sudden deafness by the end of 2011.Those who were diagnosed with osteoporosis had a 1.76 higher risk of developing sudden sensorineural hearing loss than the group without thinning bones.

　　Among those with osteoporosis, 91 were diagnosed with SSHL during the follow-up period.

　　In comparison, the control group, which was triple the size, included 155 people who were diagnosed with SSHL.Researchers aren’t sure what biological mechanism is responsible for the relationship.Dr Tien said it was possible that a number of risk factors connected with disorders including cardiovascular problems, bone demineralisation, inflammation and endothelial dysfunction may play a part.He said: ‘More people worldwide are suffering from osteoporosis, and our work shows they are at risk of sensorineural hearing loss as well as bone fracture and other problems.

　　‘Patients who have osteoporosis should be aware they need to seek medical help immediately if they experience hearing loss.’The National Osteoporosis Society (NOS) charity, of which Camilla, the Duchess of Cornwall, is president after seeing her mother and grandmother suffer from the disease, campaigns for earlier diagnosis of the disorder.
