Usher syndrome is a genetic disorder that is characterized by complications in vision and hearing; the most common of them being partial/complete loss of hearing and retinitis pigmentosa. Retinitis pigmentosa is characterized by progressive deterioration of the retina, resulting in deprivation of peripheral vision and subsequent night blindness.

The symptoms and its rate of progression usually vary among people. Usher syndrome is classified into three types:

Type 1: In this type, children are born with balance issues and hearing loss problems. The symptoms of night blindness and loss of peripheral vision associated with  Retinitis Pigmentosa  only appear in the early stages of adolescence.
Type 2: In type 2, children are born with moderate to mild hearing loss problems. Retinitis Pigmentosa develops soon after the child reaches adolescence.
Type 3: In type 3 Usher Syndrome, children are usually born with normal hearing skills, however, loss of hearing and Retinitis pigmentosa occur soon after puberty.
Causes
Hearing loss in Usher syndrome occurs when the nerve cells that are present in the cochlear (inner ear s spiral cavity) are affected by genetic mutation. A similar problem occurs in the cells of the retina leading to loss of vision. These cells allow conversion of light into electrical signals for the brain to interpret them. Both the parents need to pass the mutated gene to the child for it to be affected. If the child has only one gene, then he/she rarely develops the symptoms.

Treatment
This disorder does not have any prescribed course of treatments. The vision loss that occurs in this disorder can be slowed down by nutritional therapy. This therapy involves providing the body with essential amounts of vitamin A which can help in reducing vision loss.

Usher Syndrome - Things You Must Know!

While most noise is just in the background for us, loud noises, either in small spurts or prolonged exposure, can cause hearing loss. This has been happening more frequently as the levels of noise in an industrialized society go further up.

Noise induced hearing loss explained
Loud noises may damage the sensitive structure of your ear, which process the sound waves into information. They eventually become nonfunctional, resulting in a loss of hearing in that range. If exposure to loud noises continues, then this might extend to the entire range of hearing and may cause total hearing loss.

What may cause noise induced hearing loss?
Some of the scenarios which may cause noise induced hearing loss are as follows:
1. Listening to music on high volume: If you constantly listen to music or watch movies at your home on very loud levels, then it may result in noise induced hearing loss. In fact, listening to music or watching movies with headphones in your ears is one of the leading causes for hearing loss. Headphones have deceptively loud levels and may result in damaged hearing overtime.

2. Noise of household tools: Household tools such as drills, mixers, grinders, mowers, and saws can expose you to loud levels of noise. Even a quick exposure for a few seconds could temporarily damage your hearing. 

3. Occupational problems: Occupations such as construction, factory work and military that require the use of power tools on a constant basis can also cause hearing loss. The sound from the resulting friction might damage your hearing very quickly. Explosions and impacts are also causes of hearing loss in the military and law enforcement departments.

Prevention and treatment
Treatment: It is difficult to treat hearing loss as in most cases; it may be permanent, except sudden shocks, when your hearing might come back to normal. The only treatments for hearing loss are hearing aids or cochlear implants which can restore hearing partially.

Prevention: Prevention is the best method to avoid hearing loss and in most cases, you should wear ear protection such as mufflers or sound level reduction devices to protect your hearing. Also, practice listening to music, watching TV or movies at lower levels, especially if you are on the headphones. 

Induced Hearing Loss - Facts You Should Be Careful about It!

A deaf child is the one who suffers from hearing loss. Children with deafness may also fail to develop speech. Such children might have no defect in their speech but they cannot speak anything. The main reason is deafness. They do not hear a speech, therefore, cannot develop it. Deafness may not be hereditary, but it occurs due to several other causes. 

The period of 5 years is crucial in a child s life. During this period, they develop their speech and language. Therefore, parents need to take the utmost care for the early identification of hearing loss and treat the child accordingly. 

Causes of Deafness in Children

There are several causes of deafness in children.

Otitis Media: In young children, if the eustachian tube is not fully formed, it forms fluid behind the eardrum. This fluid can get infected and affect the hearing. The fluid may not cause any pain or infection but still, it can harm and cause hearing loss even if it stays for a short time. 

Problems by Birth: Some children have hearing problems by birth. Sometimes, the problem lies in the genes. But, other times during pregnancy or prenatal care, the problem arises. If a mother, while pregnancy, has diabetes or preeclampsia, she is likely to deliver a deaf child. A prematurely born baby also has a high risk of deafness.

Illness or Injury: Some young children suffer hearing loss due to some injury in the ear or some other illness. Illness includes meningitis, measles, chickenpox, and flu. Head injury or listening to loud music for a long time can also be a reason.

Symptoms of a Deaf Child

A deaf child shows no reaction to the loud noises.

He/she doesn t respond to the voices.

The sound of the child is simple that taper off.

The child may pull or rub the ear several times, which is noticeable.

The child is continuously cranky for no particular reason.

He/she does not pay any attention when anyone is talking.

He/she has very little energy to do anything. 

He/she fails to understand the direction.

Often asks to raise the volume of TV or radio.

Have fever and ear pain.

Treatment of the Problem

Hearing loss affects a child s learning ability. So, the problem must be diagnosed and treated immediately. Here are some treatment approaches: 

Treatment for Otitis Media: The very first thing parents and doctors can do is watchful waiting because sometimes the problem cures itself. Some pediatricians might prescribe some antibiotics. If the problems continue, then the doctor will suggest getting an ear tube to the child that will allow the fluid to drain. For this, the child will have to visit an ENT doctor also called Otolaryngologist. 

Treatment for other causes: The child may use a hearing aid. Some can get cochlear implants. 

Conclusion
It is necessary for parents to accept the child with deformity and stay by his/her side. They must get themselves educated and communicate the problem with others to get help. It is essential to stay in touch with the child and take care of him.

Deaf Child - What Should You Know?

You should consider undertaking a cochlear implant in case you are experiencing hearing loss or are turning deaf. This is a small device that gets planted in your ear through a surgical procedure. It sends impulses to your auditory nerves directly, as a result of which sound signals get carried to your brain. Cochlear implants may not make you hear normally again, but help you with different sounds, and in the recognition of the different sounds around you like alarms, telephones, and door bells.

How it works?

A cochlear implant is fit for children and adults who suffer from the sensorineural hearing loss. This condition damages the tiny hair cells in your inner ear, which is called the cochlea. Hearing becomes impaired when these get damaged.
The device consists of two specific parts. The first part or the receiver-stimulator is placed under your skin via a surgical procedure. The other part of the device is the speech processor. It has to be worn around your neck in the form of a hearing aid.
The external device is, however, larger in size than a usual hearing aid. The receiver gets placed under your skin, behind the ear via a small incision. It is connected to electrodes.
This is inserted into the cochlea of your inner ear. The surgery requires a few hours to be undertaken successfully.
The speech processor has to be placed two weeks after the surgery is undertaken. The processor can be connected to the microphone, and this can be worn around the ear.
You can wear it on any other part of your body, based on your lifestyle and age.
Benefits of cochlear implant
The major benefits of a cochlear implant are as follows:

You might be able to hear speech almost normally.
You will be able to understand speech better, and will not have to depend on lip reading.
It will be much easier and simpler for you to listen to the television and talk over the phone.
You will be able to listen to music better.
You may also be able to pick up various sounds around you that include soft, medium, and loud sounds.
You will be able to control your own voice better. This makes other people understand you better.
If you are suffering from severe hearing loss, a cochlear implant may be able to change your life for the better. However, the results are not the same for all, and vary among people. It is possible for some people to benefit more from such an implant than others. 

Cochlear Implants - 6 Benefits You Must Know!

BAHA Implant
Bone Anchored Hearing Aid (BAHA) is a device surgically implanted to help people suffering from a loss of hearing. Most conventional hearing aids transmit sound through air conduction. The BAHA device is suitable for conductive or mild-moderate mixed hearing loss.

Problems with hearing in the middle or outer ears can be helped with the BAHA device. The sound waves received by the BAHA device bypass the middle ear and get delivered straight to the functioning cochlea in both ears.

A BAHA device comprises of two parts:
a) The processor 
b) A fixture which is surgically implanted behind the ear in the bone.

The implant is embedded in the bone. The processor, which remains outside, is attached to the implant. There is a microphone on the processor that picks up sounds. The sounds are passed on to the implant. The implant vibrates which triggers the Cochlear. You can consider wearing a BAHA implant if other conventional hearing aids do not work for you. BAHA implants are also given to people with collapsed or irritated ear canals.

Cochlear Implant Surgery

A complex, small electronic device that helps hearing in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises of an external piece behind the ear and another piece that is surgically implanted under the skin. A cochlear implant comprises of four parts:
1. A microphone which picks up sounds from the surroundings
2. A speech processor which chooses and arranges the sounds the microphone picks up
3. A receiver/stimulator and transmitter that picks up signals from the speech processor and changes them into electric impulses
4. An electrode ray, a bunch of electrodes, receives impulses the stimulator sends and transmits them to different areas of the auditory nerves.
The implant does not cure deafness; it only gives you a useful portrayal of sounds in the environment and considerable aid in understanding speech.

The surgery is done in the following way:
i. The area around the site of the implant is shaved or cleaned
ii. The patient's vital signs are monitored through cables, patches and monitors attached to him or her
iii. General anaesthesia is administered through IV or through a face mask
iv. After the device is implanted, the patient is taken to the recovery room for the anaesthesia effect to lessen.

BAHA Implant and Cochlear Implant Surgery

The sense of hearing is a complex one. The ears are divided into three parts: the outer ear, the middle ear and the inner ear. While the outer ear sends the sound to the middle of the ear, the middle ear sends the same to the inner ear through the conductor. The inner ear in turn sends the auditory signal to the brain where the signal is processed and gives rise to a sense of hearing. 

Problems in hearings can arise if there is a problem in any of these parts. However, more often than not it is the middle or inner ear that is affected. However, there may also be situations when there are problems in both the middle and the inner ear. In that case, it is known as a mixed hearing loss. 

What is Mixed Hearing? 

Loss If there is damage to the middle ear, it may precipitate a conductive hearing loss. Now, in addition to that, if there is a sensorineural problem, then it gives rise to mixed hearing. So, in the case of a mixed hearing loss, all the parts of the ear and even the brain may be involved. There may be damage to the outer ear, middle ear, inner ear, as well as the auditory nerve. 

Causes of Hearing Loss 

Since mixed hearing loss may result from damage to any part of the ear, it is necessary that the causes be grouped into different categories. 

  Sensorineural Hearing Loss 

Sensorineural loss may result from drugs, different illnesses, head trauma, malformation of the inner ear etc. Genetic predisposition may also precipitate such problems. 

  Conductive Hearing Loss 

Such type of hearing loss may result from excessive deposition of earwax, ear infections, perforation in eardrums, malformation of the middle or outer ear, as well as problems with the fluid in the middle ear. 

Symptoms of Hearing Loss 

Reduced hearing in either or both ears is considered to be delineating symptoms of mixed hearing loss. 

Treatment 

Since mixed hearing loss can result from sensorineural failure as well as damage to outer or middle ear, treatment needs to be divided into different groups too.   To treat Conductive Hearing Loss, doctors can use surgical or medical options. 

  For sensorineural hearing loss, doctors usually prescribe hearing aids. This indicates that treatment for mixed hearing loss may include treatment for conductive hearing loss as well as that for sensorineural hearing loss. So, it is usually a combination of both medical and surgical options. Physicians may prescribe both medicines and hearing aids or resort to surgical interventions and also prescribe hearing aids. Sometimes, physicians use special hearing aids or implants to treat mixed hearing loss. 

Conclusion 

In case a person is sensing reduced hearing in one or both ears, he/she needs to seek medical advice. It may be a symptom of mixed hearing loss. Getting in touch with an experienced physician is the first step towards that.
