Stem Cells Restore Toddler's Congenital Hearing Loss

In a potentially revolutionary treatment, a two years old toddler born deaf has had her hearing restored after receiving stem cells from her banked umbilical cord blood. (Reported in ABC News)

Madeline Connor at age 1 year old was completely deaf in the right ear and had severe hearing loss on the left. Normally hearing aids or cochlear implant would have been the only options.

However, in January 2012 at the age of 2 years old, Madeline underwent a "simple" experiment whereby stem cells were infused into her damaged inner ear. The stem cells were derived from umbilical cord blood that was banked at the time of her delivery at the Memorial Hermann-Texas Medical Center.

Over the next 6 months, there has been dramatic improvement in her hearing. She is also now talking for the first time.

Madeline also is not the only child who has undergone this revolutionary stem cell treatment. Apparently, there are ten other children who are being followed after undergoing similar stem cell infusion derived from banked cord blood.

It must be stressed that though Madeline's progress is quite amazing, it is still too early to say if this is a "bona fide" treatment for congenital hearing loss.

• Will the improvement continue and more importantly, last over years to decades?
• Will it work for other children?
• What is the expected hearing improvement with stem cell infusion?
• Will it treat ALL forms of nerve-damaged hearing loss?
• Does it have to be stem cells derived from cord blood or are stem cells derived from other sources possible (i.e., skin)?
• Can adults with non-congential hearing loss also benefit?

I eagerly await the outcome of this FDA approved trial which hopefully will be published at some point in the near future.

I also eagerly await the protocol used to obtain and infuse the stem cells. I suspect the infusion of stem cells is similar to that done when steroids are infused into the ear for sudden hearing loss as shown in this video below. However, this is just a guess of mine.

Katie Couric Gets a Hearing Test

On July 10, 2012, Katie Couric reported on a personal story during which she obtained a hearing test.

In a modern society like the United States, there are many sources for hearing loss with our alarms, lawn-mowers, and loud music.

As the article correctly pointed out, damage due to loud noises is due to two factors: loudness and duration.

The louder something is, the shorter time of exposure before hearing damage can occur. The quieter something is, the longer a person can listen before suffering noise-induced hearing loss.

Otherwise, hearing aids may be in your future... even if you are in your 20s or 30s!

Phone App That Measures How Loudly You Listen to Your Music!

There are plenty of sound meters in the market for iPhone and Android smartphones that tell a user how  loud the surrounding noise is. Many of these apps are free.

However, rather than recording the loudness of the surrounding environment, there is now a new phone app called Safe and Sound (only for Android phones) that measures the decibel level of the sound emitted from headphones and gives the user a clear indication of how loud their music really is. Furthermore, it also records the user's listening history and alerts them when they are close to their daily recommended dose of noise exposure.

It is free as well!

Listening to loud music has become an increasing concern as hearing loss is being seen at earlier and earlier ages with increasing need for hearing aids. Complaints of tinnitus is also present.
