Love the ear to pay close attention to on day: It is deaf to prevent and control children Begin from the gene sifts checking
Measure and can defend in early days " It is deaf that a stitch is caused "
The children under the age of 7 of our country, because unreasonable uses antibiotic to cause the deaf quantity up to 300,000, accounts for 30%- 40% of overall deaf and dump children. Among them, it is that " deaf that a stitch is caused " because of injecting Streptomycin as a child that the overwhelming majority is deaf ,Have lost hearing forever. National deaf disease molecule epidemiology makes investigations to reveal, 4.4% of the individuals carry mitochondrial gene mutation in Chinese deaf person's colony, will initiate hearing to drop after using the amino sugar glucoside medicine represented by Streptomycin.
The Streptomycin medicine of person who wait for deaf to belong to acquired, inherent cause and inborn defect that environmental factor lead to the fact jointly, the early deaf genetic test can find the potential infant. If mother sift, find that there are medicines nature deaf genes when being pregnant, avoided using the toxic medicine of ear, can protect the hearing health of mother and child at the same time, can prevent from " deaf that a stitch is caused " Emergence.
Besides inborn dysaudia, hereditary deafness can also show by way of sending dysaudia late. The late hair deaf characteristic is: Suffering from to the late hair deaf person often has a very good speech foundation; The late hair deaf course is progressive; Late hair hereditary deafness usually relates to hereditary gene. Though late hair deaf to take place in the short time, until whom hearing lose aggravate, will still work and study and exert an influence to people. Because the late hair has disguise deafly, the traditional inspection method will unavoidably be omitted to some extent. As to this kind of patient, may define its real cause of disease in deaf genetic test, help doctors and patients to take the pointed protective measure in order to protect residual hearing, prevent hearing from damaging and aggravating. Meanwhile, check and diagnose the corresponding genetic sieve in teenagers' deaf philtrum, make them understand one's own pathogenic reason, can avoid and there is deaf gene mutation that causes the opposite sex of the deaf deaf person to combine too effectively, can prevent the deaf - deaf transmission phenomenon effectively.
It is single genetic disease that most heredity are deaf
There is disabled crowd 27,800,000 of hearing now in our country, occupy the first of all kinds of deformity (33%) ,Deafness is one of the common inborn defects too at the same time.
From U.S.A. hereditary disease study the intersection of expert and statistics of Mckusick, show, genetic disease already known at present has 4000 multi-type, including anaemia of Mediterranean, mongolism, deafness,etc.. As to the genetic disease, through checking the genetic state, can find the risk of the inborn defect clearly. When cause deaf reason in all, the inherent cause is causing the deaf main reason born, the proportion is up to 60%. In addition in a large amount of late in sending hearing drops the patient, also a lot of patients are caused a disease by one's own genetic defect, or cause a disease because genetic defect and many attitudes cause and increase in causing the deaf environmental factor to be easy to be perceptual.
