Celine Dion Cancels Shows Due to Laryngitis

In late Feb 2012, Celine Dion who was to have performed in Las Vegas Feb 22, 2012, cancelled her show at the last minute at the Caesar's Palace due to laryngitis on the advice of her doctors. According to media reports, her doctors instructed her to rest for 7 days to ensure full recovery due to vocal cord inflammation caused by a virus.

What does that mean exactly?

When a virus infects the mucosa of the upper airway, it causes inflammation of the mucosa lining including the vocal cords. With inflammation, the vocal cords swell.

That's why with laryngitis, the pitch of the voice decreases and it becomes more effortful to talk. To use an analogy, think of a violin string where the thicker string has a deeper pitch than a thin string. It also takes more power to play the thicker string. Watch the video below of normal vocal cord functioning:



In order for voice production to occur, the lining of the vocal cords vibrates very quickly when they come together. If the vocal cords are swollen, they don't vibrate as easily.

Here's what inflamed vocal cords might have looked like for Celine Dion. Note the slight bend to the vocal cords and overall dull appearance.

Below is what her vocal cords might look like when they are at peak health!

Voice rest is absolutely important for vocal recovery as quickly as possible. With talking/singing during active laryngitis, further trauma may occur to the vocal cord lining promoting even more inflammation and swelling. It may also lead to another vocal disorder known as muscle tension dysphonia.

Natural Remedies for a Sore Throat, Cough, and Viral Infections

Homeopathy and alternative medicine often get a bum rap, but they have come up with some treatments for sore throats and upper respiratory viral illnesses that actually have been proven to work.

Here's a few...

1) Honey

Sore throats (and coughing) can be soothed by swallowing honey straight-up or slightly diluted with warm water with honey to make it easier to swallow. The best time to do this is at bedtime given it will stick around for awhile (eating/drinking will wash away the coating). The purpose of honey is to create a throat barrier to ease the discomfort.

Think of it like chapstick to coat irritated lips, but meant for the throat.

Use of honey is also recommended by the World Health Organization which has also published a monogram on viral colds and the various treatments explained. Pay particular close attention to Annex 3 (Page 11) which gives various recipes to treat pediatric cough including the use of honey.

2) Humidification

Dry cool air increases risk of viral infections as well as giving it to others. As such, add room humidification to a bedroom and keep the door closed (small room humidifiers can't humidify an entire house... so keep door closed!).

Why does this help? Increased humidification inactivates viruses!

Humidification also helps minimize a persistent dry cough worse at night often due to reactive airway disease triggered by breathing in dry air.

However, keep in mind that if you actively have a viral illness, it is too late for humidity to help. It is best used as a preventative measure.

3) Gargling and Saline Flushes

Gargle with saline water... or even just tap-water on a daily basis. Why does this help prevent viral infections? It washes away the viral particles before it gets a chance to cause problems.

It's also probably why drinking lots of fluids also helps since the viruses get deactivated in the stomach from the acidic digestion.

Unfortunately, gargling only helps with the throat... saline flushes are required to help with sino-nasal problems.

4) Xylitol

This naturally-occurring sugar substitute apparently has all sorts of anti-bacterial as well as anti-fungal properties and has been known to doctors and scientists but hardly marketed or promoted in any fashion.

However, the importance of this compound is that it DOES appear to significantly decrease the incidence of ear infections and sinus infections when used regularly. It comes in nasal spray form as well as gum.

Conclusion

Sometimes the BEST medicine are things you can do at home without need for a physician visit... and is based on fact rather than anecdotal evidence.

Test That Distinguishes Between Bacterial or Viral Infections

From the pages of CSI: Miami... a commonly used forensic chemical called luminol to identify traces of blood at crime scenes has been modified to be used in a novel medical test that can help differentiate a viral infection from a bacterial infection.

Why is this important?

Not uncommonly, it is sometimes hard to differentiate between a bacterial infection which is treated with antibiotics from a viral infection which is NOT treated with antibiotics. Unfortunately, in the healthcare system, too often, antibiotics are given if an infection is present whether viral or bacterial which is leading to multi-drug resistant infections like MRSA.

Well with this test, physicians can potentially use it to determine whether antibiotics should be provided or not. Such a test may also be reassuring to patients who desire antibiotics, but can be told with confidence that it is not necessary and at worst, dangerous.

The way this test works is by identifying the characteristic glow "signature" after luminol is applied to a suspect infection. If it glows a certain way... it's a viral infection. If it glows in a different way... it's a bacterial infection.

For those scientifically inclined and curious, the glow is due to a byproduct of the body's defenses fighting off infection called "Reactive Oxygen Species". The luminol reacts with this byproduct creating a glow.

Of note, the test is not yet available, but perhaps soon???
