Scientists are exploring new avenues for restoring hearing loss in adults.

Researchers have tracked a cell-to-cell signalling pathway that designates the future location of the ear’s sensory organs in embryonic mice. The scientists succeeded in activating this signal more widely across the embryonic tissue that becomes the inner ear.

“As the population ages, there’s a great interest in discovering how to regenerate the inner ear sensory cells that we need for our hearing and balance,” said Olivia Bermingham- McDonogh of the University of Washington.

“Both of these falter as we get older – we get hard of hearing and unsteady on our feet – due to accumulated destruction of the sensory cells in the inner ear,” she added.

The goal of their research is to develop ways to restore inner ear sensory hair cells in people who have lost them due to age, excessive noise or other toxic damage.

In order to devise a way to restart hair cell formation in the adult ear, Bermingham-McDonogh’s group studied how hair cells are made in the first place during ear development. They could encourage the formation of new building foundations throughout the inner ear. Once these new sensory patches were made, new hair cells and support cells were properly produced within them.

So by starting the ball rolling with the Notch signal, the researchers observed that the rest of the developmental processes followed along correctly.

The team is now studying ways of manipulating the Notch pathway in the adult inner ear to see if this will stimulate hair cell regeneration in the hearing and balance organs. If ways could be found to safely re-start particular Notch signals in adults, therapies might be designed to regenerate specific tissues, like nerves, and thereby repair damage and restore lost function, like hearing.

The findings are reported this week in the early online edition of Proceedings of the National Academy of Sciences.

A good workout in the gym is important for many reasons including you weight, muscle tone and lung and heart health but for those who listen to their mp3 player whilst working out they may be doing more harm than good.

A new investigation carried out involving subjects listening to the same music in three different places has had interesting results. The subjects were each placed in a quiet environment whilst resting, a noisy environment whilst resting and exercising on an exercise bike.

It is a proven fact that people are generally listening to their mp3 players at safe levels when the environment they are sitting in is quiet. When the background noise goes up it seems the volume level on the mp3 player is also turned up.

The new study highlighted the fact that people purposely increased the volume on their mp3 players when they entered an environment where the background noise levels were high. Working out in a gym was one place where people were frequently shown to be turning up the volume.

When you are working out in the gym there are many different sources of noise being omitted around you. Televisions, radios, the noise from equipment and general chatter all increase the background noise levels. Heavy breathing whilst working out also adds to the volume. Some of the participants also freely admitted that they increase the volume in order to pump themselves up at the start of a workout.

It is proven that people listening to music in a quiet environment choose to listen at a lower level as there are no other competing sounds surrounding them.

Some previous studied agree that the louder the noise in the background the higher people adjust the mp3 volume level to. Researchers discovered that whilst working out people turned the volume up to 75% of the capacity which leaves them at high risk of hearing damage.

Investing in a set of headphones that block out all background noise is a good way to ensure that you won’t be tempted to turn up the volume.

Deafness claims can be pursued via a qualified solicitor. Tinnitus Claims are also often pursued by people suffering from work place hearing damage.

The Vuvuzela is now a key symbol in the history of the 2010 World Cup in South Africa. The sound of the vuvuzela instrument was the topic of much discussion throughout and after the end of the World Cup. Although many people considered it to be seemingly harmless the vuvuzela does pose health risks. It generates an extremely loud monotone sound when played, one which has been an irritation for many football fans worldwide since the World Cup began.

The noise resulting from the Vuvuzela has been proven to cause hearing loss when the exposure levels are high such as during a packed football stadium of fellow fans all blowing on them. The noise alone was considered beyond irritating by many.

Charity Deafness Research UK have now discussed the Vuvuzela stating that; ‘The competition could also score an own goal – with football fans risking permanent noise induced hearing loss, from the constant use of Vuvuzela horns.”

Lots of South African football fans regularly use Vuvuzelas and are therefore used to the sound produced, the same cannot be said for the thousands of international supporters watching the world cup. Although many called for a ban on the Vuvuzela it was overturned as the instrument was said to be an important part of the African culture.

The deafening pitch created by the Vuvuzela can eventually lead to serious health problems relating to the ears which confirm the fears the fans present at the world cup had. Deafness Campaigners are now looking to prevent them from being used in future football and sporting events.

There is already many different risks to people in the UK regarding noise induced hearing loss, adding to it with the use of Vuvuzelas is not something health campaigners will be happy to let happen. Work place noise induced hearing loss is a common problem here in the UK, having the Vuvuzela present in leisure time could see many people suffering.

If working in a noisy environment has affected your hearing, then you may have a case for a noise induced hearing loss. Visit the What’s My Deafness Claim Worth site to learn more about how to begin anindustrial deafness claim.

Allergy occurs in many little school-age children. Up to 30% of children have symptoms of nasal allergic reaction, including runny nose, crusty and stuffy nose, exhausting sneezing, and itchiness. The source of allergies in children can be house dust mite or food.

Allergy also demonstrates in recurring and heavy coughing that can last up to two weeks. In some cases, the allergic attack can occur at nighttime, with the child’s sleep being distressed by persistent, irritating and exhausting coughs, accompanied with choking and purging. This type of allergic manifestation is both hard for the kid and for the parents. Because the child misses sleep, she finds it hard to wake up in the morning, thereby impacting her school performance, her mood, and setting her physical activity. With the child being irritable, parents are more prone to being cranky and losing their patience over the child’s needs.

There is also the emotional challenge of the parents watching the child battle with and suffer from the allergy. Parents face the challenge of the requirements on their time, patience, and physical exertion because indeed, managing with a child’s allergy may take away a lot of time from rest and other recreational activities. Children on the other hand also face a rather challenging time playing the games they used to play or doing other physical activities because of the restrictions of their freshly acquired allergic response.

To attempt help, parents can turn to eyes, ears, nose, and throat doctors and other specialists who can care allergy with treatments. These may take on introducing ways to take away potential source of allergens at home, and administration of anti-allergies medications like antihistamines, nasal sprays, nebulisation, and others.

Parents can do easy touch ups at home to help keeping the cause of allergens away, like clearing the dust off regularly, letting more fresh air through the windows as long as the pollens are kept outside, and keeping indoor air quality in top shape with the airconditioning on.

With help from doctors, every parent can successfully care for allergy of their young school-age children. For allergic responses aggravating into asthma, parents should see a paediatrician right away.

When a child coughs, parents are troubled and fearful especially with coughing that persists up to two weeks and which bother and beat the child. Some coughing also comes with vomiting, and leaves the child beaten. In fact, a child can cough the hardest at night, and this robs her of rest which her body needs to recuperate and become strong for the cough again.

A fact about cough that parents need to appreciate is that it is not a disease that necessitates a cure. Coughing is the body’s ready reflex to release phlegm from the lungs and the throat where, mixed with bacteria, it may cause an infection. Coughing is indeed good. And kids who know how to cough without aid from parents are doing great releasing the nasty sputum. There should generally be no worries over coughing that lasts up to 2-3 days and where the sputum is clean and not yellowish.

In coping with a child’s cough, the best thing parents can do is to assist the kid become strong. Coughing can be so strenuous, and with lack of sleep, the kid’s immune system may drop, leading to vulnerability to diseases and viral infections. Taking lots of water and juices, fruits, rest, and doing frequent hand washing can help the child’s body become terrific to manage the bad results of hard and recurring cough. This natural water therapy can be reliable for a duration of one week.

Coughs that persist for over two weeks signal an alarm. In this case, parents should see a physician for a thorough diagnosis of what illness the cough may be providing a symptom of. The physician may prescribe medication which will be allotted for one week.

If this still fails, then going to a medical specialist is important. The cough may be indicating an allergic reaction, or worse, asthma.

A word of caution to parents: Never give children an adult OTC cough medicine as these have bad effects on the kid. Cough medicines also do not heal the cough, they simply ease the child of the irritations related with coughing such as runny nose, sore throat, losing breath, fever and tiredness.

Bring the child to a physician for the most trusted approach to cough management.

Like me, most people have faked our way through school chorus and church choir by mouthing our way all because we can’t sing very well. While they may actually enjoy the act of singing, such as in the car or while taking a shower, they’re sure to do it only when they’re alone. But if you think of yourself as being tone deaf, you’re certainly not alone. There are about one in seven people that believe they are tone deaf.

Most people think being tone deaf means you just can’t sing, but actually lots of lousy singers have no problems whatsoever hearing music, and they like to listen to it just as much as anyone. When the actual meaning of tone deaf is used, which is just for those who are not able to understand music, the number of people who are actually tone deaf is decreased. In some studies, it has been discovered that approximately only 1 out of every 20 people actually suffers from tone deafness. Tone deafness means that you are unable to distinguish between different pitches, that is how high or how low a note is, making it nearly impossible to identify even a simple tune.

Those who are severely tone deaf are referred to as having “amusia” amongst medical professionals. When you are born tone deaf, you are considered to have congenital amusia. Montreal Battery for the Evaluation of Amusia is a series of tests that researchers created to comb through the different kinds of musical deficiencies. Fascinating research using imaging tests make it possible to compare the brains of those with what are considered normal music abilities with those of a bona fide musician.

Genuine curiosity concerning the functions of the brain relating to the form of music encourages a large percentage of such studies. Currently, there are no researchers working on finding a cure for the tone deaf. Through discovering the mysteries of amusia, scientists hope that they will solve other challenges, including learning disabilities, and they believe that amusia itself could help one day with treating a number of alternative developmental disabilities.

In terms of the organizational structure of music, in the Western world we use half steps (also referred to as semitones) to classify the difference between musical notes. The majority of humans are able to detect the differences between musical notes easily; in fact, many of us are able to recognize fractional changes between semitones. Differences in pitch are much more difficult for those with amusia to distinguish, and often requires a considerable tonal difference before it is detected.

Pitch contour, pitch direction and pitch isolation seem to elude the hearing abilities of the tone deaf. The changes in the contour of a pitch are what ultimately form the melody of a song. Distinguishing changes in pitch within a musical phrase is an especially challenging task for those who have been classified as amusic.

The mechanics of rhythm seem as difficult to grasp for one who suffers from amusia as melody and pitch. However, if the music played is monotone with no variations in pitch, amusics display a good rythmic sense. Because rhythm and music are usually rather intrinsic, it’s certainly understandable that the pitch of the musical piece would hinder those with amusia, causing them to have trouble following the beat.

The HSE have announced a brand new initiative aimed at encouraging manufacturers to make quieter machinery and businesses to use the quieter machinery. They have done this in a bid to try to reduce the amount of noise related health problems created in the workplace.

It has been estimated that 170,000 people within the UK suffer from hearing complications due to being exposed to high levels of noise in the workplace. The initiative ‘Buy Quiet’ has been designed to educate people to what they can do in order to reduce noise levels.

The HSE are particularly interested in building a closer working relationship with manufacturers and understanding what can be done to make reductions at work.

An event was held in March 2010 where the relevant businesses and organisations met up to debate how noise plays a big role in their daily lives and how it can impact on your hearing.

The workshop aimed to give information on the legal rules regarding noise levels and to help employers acknowledge the risk factors that are associated with noise induced hearing loss.

By law employers are required to monitor noise levels under The Control of Noise at Work Regulations Act. There are duties that employers have to fulfil in order to look after the interests of their employees. All employers must assess the risk to their employees and take action to reduce the noise levels if the risk assessment shows there is a need to. In some cases employers will be required to provide their employees with protective hearing protection if the noise levels cannot be controlled any other way. A duty of care is owed to employees and noise levels must be controlled and not exceeding the recommended safe level. Health surveillance tests should be undertaken when there is said to be a risk to the health of any employee.

Deafness claims can be pursued via a qualified solicitor. Tinnitus Claims are also often pursued by people suffering from work place hearing damage.

Glue ear is a common condition where glue-like fluid collects in the middle ear, behind the eardrum. It is the most common cause of partial deafness in children. About one out of four children get affected by glue ear at one point of their childhood. It is more common in boys, being the most affected between ages two to five. However, there are still risks it can occur at later stages, including adulthood.

Glue ear, unfortunately, is sometimes overlooked. There are some signals though, such as temporary hearing loss and a stuffy feeling in the ears.

Glue ear is very common though. One occurrence predicts another. It has been known that children who have had one episode of glue ear are more likely to have recurrent episodes.

Other risk factors that may contribute to higher risk of glue ear include:

- constant exposure to nicotine smoke

- often having cough & cold

- glue ears is common in the family; and

- as a baby, he or she was bottle fed rather than breast fed

The most common symptom of glue ear is having dulled hearing. Sometimes, children who are affected might end up deaf completely. Hearing loss can vary from mild to severe. If it persists, it will affect the child’s normal intellectual development.

Pain is a very uncommon symptom, but mild earache may happen from time to time. Some affected children might pull at their ears if they have pain.

Children who have glue ear tend to show slower speech development and even behavioral problems. These are commonly caused by the fact that their hearing is impaired.

Fortunately, glue ear can be treated. Also, most glue ears will heal on their own. However, if glue ear persists, surgery may be required to remove the glue-like fluid from the middle ear and to place a ‘grommet’ (ventilation tube) in the ear drum. It sits across the eardrum, connecting the middle and outer ears, hence allowing pressure in the middle ear to normalize or equalize with the atmosphere.

There’s likely nothing that stimulates one’s curiosity about the cough. Cough can be wet, whopping or dry. You could fake a cough to relieve you from embarrassment, or blast dagger looks at someone coughing to your face; worse, you could be having a coughing fit. But really, there seems to be a lot more you many not recognize about the cough.

Super fast is how cough travels, that is why it is common. Cough moves swifter than a mere mortal. It’s at 60 miles per hour, the speed of cough!

Here’s one intriguing information about the cough: snail gunk could be a remedy for it. In Chile, snail guck is commercialized as a treatment for the common cough. Avers the proprietor of the snail farm, antibiotics are in these slimey secretions and they work well against cough. In Chile, at least, cough medications from snail slime come in strawberry and avocado flavors.

But long before the snail and its gunk, otc and prescription cough syrup formulations were derived from addicting substances… or didn’t you know? Yes, drugs were given freely then, even to children! Opiates and heroine were the origin of cough syrup in the 1800s!

The destinies of cough syrup and Jello looked to have been intertwined, too. Closing his factory of cough syrup, Pearl B. Wait decided to venture into something else. He opted to better the nasty-tasting gelatine and gave the world Jello, in fruity flavors.

Cough even caused execution- a not-so-known trivia. Yes, in 1799, Napoleon was ruminating whether to free his 1,200 Turkish captives or not. But he coughed and cried “Ma sacr toux!” (translation: My darned cough!) But his soldiers believed he pronounced, “Massacrez tous!,” which meant “kill them all!” And so, they did.

Does coughing bring on hearing deterioration, as well?

Nasal polyps are small, soft, jelly-like nodules within the nasal passages. Smaller nasal polyps are quite harmless, but large ones make breathing difficult because of the blockage they create.

Knowing the early warning signs can help you get diagnosed and treated immediately. Here are 7 symptoms or warning signs that you have nasal polyps. Should you experience them, inform your doctor (an ears, nose and throat or ENT specialist) as soon as possible. He can perform tests and detect your problem right away.

1. Breathing through the mouth – Any obstruction of the nasal passageways can force you to breathe through your mouth. However, if mouth breathing has become chronic, or if it is not associated with a cold, nasal polyps may be causing this.

2. Runny nose – A runny nose with no other associated symptoms may be caused by nasal polyps as well. Allergies can cause a runny nose, but they may also cause enlargement of present polyps. This makes symptoms more noticeable.

3. Persistent stuffiness – Nasal polyps may also cause a stuffy feeling in the nose. It can cause your passages to be blocked, affecting one or both nostrils.

4. Chronic sinus infections – Chronic sinus infections may also be caused by nasal polyps. These infections are more likely to happen after a cold, because nasal polyps can become infected and cause passageways to hold more mucus than normal.

5. Sense of smell is lessened or lost – Nasal polyps can cause loss of smell, because they cover the membranes that lets the human body detect odors.

6. Dull headaches – If you experience a lot of dull headaches, similar to a sinus headache, nasal polyps may be the cause. Nasal polyps create pressure in the nasal passages, triggering the headaches.

7. Snoring – Snoring has several causes, but chronic snoring is often caused by nasal polyps.

Remember that only an ENT doctor can identify and diagnose nasal polyps. The above mentioned are just some early symptoms that suggest you may have them. If you have these symptoms, speak to your ENT doctor at once.
