Occupational Hearing Loss

Prolonged exposure to noise at or above 90 decibels especially if the noise is high-pitched, can damage the sensitive hair cells lining the cochlea, the innermost part of the ear. This may cause partial to severe hearing loss. Some occupations that are particularly hazardous to unprotected ears are heavy construction, driving a tractor, and working around very noisy equipment. Exposure to loud rock music over long periods of time also endangers your hearing.

What should be Done?

Sensorineural hearing loss that is caused by damage to the cochlea is irreversible. Therefore, prevention is crucial. If you are exposed to dangerous levels of noise, you should wear suitable ear protectors. Ear muffs that are designed for the purpose are the most effective. They resemble earphones and almost totally insulate the ears from noise. If the wearer needs to communicate with colleagues, as on the flight deck of an airplane, a small microphone and earphones can be added to the muffs. The second most effective protectors are ear plugs made of foam, plastic, wax or rubber.

If you work in very noisy conditions, have your physician test your hearing at regular intervals. If you detect loss of hearing early. you can take steps to prevent further damage to your ears. If you think that the noise level where you work is too high, you can contac: the person responsible for safety in your plan: or your union representative. You can also contact the local office of the Occupational Safety and Health Administration (OSHA) or the local health department, and file a complaint.

Labyrinthitis – Curing Labyrinthitis

Labyrinthitis - Treatment and Fast Cure for Labyrinthitis

In labyrinthitis, the labyrinth, a group of fluid-filled chambers that controls balance, becomes infected. The infection is usually caused by a virus. It inflames the labyrinth and totally disrupts its function.

What are the symptoms?

The main symptom is extreme vertigo, or dizziness. You feel off balance, and everything seems to be spinning in a circle. Your eyes move slowly sideways, then flick back to their original position. If you move your head, even only slightly, the vertigo gets worse. In some cases, there is extreme nausea and vomiting.

What are the risks?

Although labyrinthitis can be very debilitating, it is not a dangerous condition when cared for properly. The symptoms are often so distressing that few people who have it do not seek help.

What should be done?

If you have severe vertigo, see your physician at the first opportunity. If you cannot travel, ask your physician to come to you. The doctor will try to determine whether the vertigo has some cause other than labyrinthitis. One possibility is an infection that has spread from the middle ear.

What is the treatment?

You will probably have to rest quietly in bed for several days. Y our physician will probably prescribe a tranquilizer and a drug that is used to combat nausea. The symptoms of labyrinthitis can be frightening, but they will probably disappear. Most cases clear up completely, within one to three weeks.
