The Importance of Vaccines

There has recently been a serious outbreak of measles, with over 100 confirmed cases across 10 states.  I thought we should talk about the importance of having your children, and yourself, vaccinated for measles along with other infectious diseases.

Measles and other infectious diseases are still common in some parts of the world.  We often forget how serious these diseases can be, because we don't see them much anymore due to previously high vaccination rates.  Childhood infectious diseases are no joke.  They are serious infections that can be deadly.

Prior to the introduction of the measles vaccine in the mid-1960s, there were 3 to 4 million cases of measles in the US every year, leading to about 48,000 hospitalizations each year, about 1,000 cases of brain damage each year, many cases of deafness, and a minimum of 450 deaths every year just from the measles.

When vaccines were first developed, parents often stood in very long lines waiting to get their children vaccinated, because they knew how serious these infections could be.  They had seen children die or have very serious complications which caused lifelong disabilities.  They could not wait for their children to be protected.

Through vaccination, measles had actually been totally eliminated in the US by the year 2000.  Unfortunately, something very bizarre was happening around that same time.  People started spreading fake claims that vaccines were bad for us.  First they claimed that vaccines caused autism.  Now that this claim has been thoroughly debunked by reputable science, their tactic has changed leading to other false claims about vaccines.

The spreading of ignorant, false information puts all of our children at risk!

The vaccination schedule is developed by the CDC, based on recommendations from the Advisory Committee on Immunization Practices (ACIP).  The ACIP is a group of medical and public health experts that are carefully chosen based on the expertise in various fields of medicine, including vaccinology, immunology, pediatrics, virology, infectious disease, and other fields.  Certain people are not considered for ACIP membership, including people who have any link whatsoever to a vaccine manufacturer.  This committee meets three times every year and reviews all of the vaccine research and scientific data related to vaccine effectiveness and safety.  Between the meetings, they work in groups all through the year to stay up-to-date on all of the latest research.  The committee makes recommendations based on a wealth of scientific information, with consideration given to the safety and effectiveness of a vaccine when given at specific ages, the severity of the disease, and the number of children who get the disease if there is no vaccine.  This is a rigorous process designed to protect the health of our children.

One example of the great impact vaccines can have is the total eradication of polio in the US.  Polio was once the most feared disease in America, causing death and paralysis across the country, with over 55,000 cases confirmed in 1952 in the US.  Thanks to vaccination, there are no reports of polio in the US today.

Here are some basic facts about vaccines to keep in mind…
  • Vaccines are both safe and effective.  Although any vaccine can cause side effects, for the most part, these are minor and resolve within a few days at most.  To see a comprehensive list of potential side effects from any vaccine, use this link.   https://www.cdc.gov/vaccines/hcp/vis/current-vis.html
  • Vaccination is the best way to protect children from preventable diseases.
  • Vaccines protect the children who get them, and their families.
  • High vaccination rates in healthy children can also protect children who are still too young to be vaccinated or who are unable to get vaccines due to serious medical conditions.
  • There is a high cost, both financially and medically, associated with vaccine-preventable diseases.
As infectious diseases threaten to reappear, we should be vaccinating more, not less.

Valentine's Day Heart Trivia

Since Valentine's Day falls this week, I thought the heart seemed like a good theme for this week's Health Tip.  Here are a few interesting items about your heart that you might not know.

How big is your heart?
Throughout your lifetime, your heart is about the same size as your fist.  It grows at about the same rate as your fist grows.

How long does it take for blood to get around the body and back to the heart?
About once every minute and a half your blood makes a complete round trip through your body.  That is about 1,000 times every day.

When was the first heart surgery performed?
In 1893, a prominent African American surgeon named Daniel Hale Williams performed the first cardiac surgical procedure in the US when he successfully repaired a tear of the outer layer of the heart.

Is chocolate good for your heart?
The answer is that chocolate can be both beneficial and harmful.  Consuming chocolate in moderate amounts has been shown to be associated with a reduced risk of cardiovascular disease.  Unfortunately, consuming chocolate in higher amounts actually cancels out the benefits, and then some, as a result of the higher sugar consumption.  Dark chocolate does contain less sugar, so you can eat a little more dark chocolate than milk chocolate.  Chocolate also contains a small amount of a cardiac stimulant, so for some patients, chocolate has been linked to a type of arrhythmia of the heart.

Is there a link between your heart rate and how long you will live?
There is actually abundant evidence that in all warm-blooded mammals, including humans, there is a link between heart rate and longevity.  The higher your resting heart rate, the lower your life expectancy.  Resting heart rate is most likely a result of both genetic factors and your lifestyle.  Regular exercise for instance, typically causes your resting heart rate to decrease.

Can you really die from a broken heart?
There is a type of cardiomyopathy, Takotsubo syndrome, which is also called "stress cardiomyopathy" or "broken heart syndrome."  This cardiomyopathy is a result of severe emotional or physical stress.  Severe stress causes elevation of pro-inflammatory chemicals in the blood which significantly increase the level of inflammation in the body.  Individuals who experience profound grief as a result of the loss of a spouse can have levels of inflammation high enough to cause heart damage.

What is Holiday Heart Syndrome?
Holiday heart syndrome is an acute disturbance of the heart's rhythm which is linked to excess alcohol consumption.  People often consume excess alcohol around certain holidays, leading to increased arrhythmias during or shortly after a holiday.  Atrial fibrillation is the most common arrhythmia seen.  The most common holidays associated with this condition are Thanksgiving, Christmas, and New Year's Eve.  It does not appear to be linked to Valentine's Day.

Does laughter benefit your heart?
It is true that laughter is good for your heart.  A hearty laugh can prompt blood vessels to expand then contract, which can increase your blood flow by up to 20%.  That can promote healthy blood vessels, which can help to ward off cardiovascular disease.  Laughter also helps to relax the whole body and trigger the release of endorphins.  It can lower blood pressure, reduce stress hormone levels, and improve immune function.  Sustained laughter is actually a good cardio workout.  It gets your heart pumping and burns about as many calories per hour as walking at a slow to moderate pace.  Laughter may really be the best medicine!

Dry Skin – Is It Serious?

Most people will have dry skin from time to time.  Some people do have more serious dry skin conditions, but for most of us, dry skin is caused by environmental factors that can be addressed or controlled.  You can do a lot to improve the condition of your skin, without seeing your doctor.

What are the symptoms of dry skin?

Symptoms can vary depending on your age, where you live, your overall health, as well as many other factors.  Here are some of the most common symptoms of dry skin:
  • Tightness of the skin
  • Skin that feels or looks rough
  • Itching
  • Flaking, scaling, or peeling of the skin
  • Cracking of the skin, which can sometimes be severe enough to bleed
  • Redness
  • Gray or ashy appearance
What can cause dry skin?
  • Low atmospheric humidity - If you live in a desert region, the air is dry all year round.  In other areas, the humidity levels plummet during the winter.
  • Heat - Central heating, wood-burning stoves or fireplaces, and space heaters can all reduce the humidity in your home.
  • Hot showers - Taking long, hot showers can wash all of the protective oils off your skin.
  • Harsh soaps or detergents - Many soaps and shampoos can strip the oils from your skin.
  • Exposure to chemicals - Cleaning products contain drying chemicals.  Chlorine in pools also causes drying of the skin.
  • Medical skin conditions - Patients with eczema or psoriasis are prone to dry skin.
How can you prevent or treat dry skin?
  • Humidify the air - If your local humidity is very dry, whether seasonally or year-round, consider a humidifier for your home.
  • Moisturize - Use a thick moisturizing cream every day, especially just after your bath or shower to keep moisture from escaping through your skin.  If you have to wash your hands frequently, consider using a small amount of moisturizer after each washing.
  • Limit water exposure - Keep baths or showers to 10 minutes or less, and try warm water instead of hot.  Wear rubber gloves if you have to expose your hands to water frequently.
  • Avoid soaps or shampoos that are drying - Try soaps with added moisturizers; try a moisturizing shampoo; use a moisturizing conditioner after you shampoo; avoid antibacterial soaps.
  • Avoid hand sanitizers and other alcohol-based products on your skin as much as possible.
  • Avoid folding clothes that have just come out of the dryer.
If your dry skin does not improve despite all of these measures, you might have a more serious medical skin condition, such as eczema.  If you have open sores, large areas of redness, peeling or scaling skin, or itching that interferes with your sleep, you should see your doctor to have it evaluated.
