Children and Indoor Molds
(More Information on Children and Mold HERE)
Asthma is increasing in alarming numbers
across the country. The clinical diagnosis of asthma includes a variable
airflow and an increased sensitivity in the airways. This condition can
develop after a reaction to a specific agent (allergen) and may cause a
life-threatening situation within a very short period of exposure. It can
also develop after a long-term exposure to irritating agents that cause an
inflammation in the airways in the absence of an allergen.
Several environmental agents have been shown
to be associated with the increased incidence of childhood asthma. They
include allergens, cat dander, outdoor as well as indoor air pollution,
cooking fumes, and infections. There is, however, increasing evidence that
mold growth indoors in damp buildings is an important risk factor. About
30 investigations from various countries around the world have
demonstrated a close relationship between living in damp homes or homes
with mold growth, and the extent of adverse respiratory symptoms in
children. Some studies show a relation between dampness/mold and objective
measures of lung function. Apart from airways symptoms, some studies
demonstrate the presence of general symptoms that include fatigue and
headache and symptoms from the central nervous system. At excessive
exposures, an increased risk for hemorraghic pneumonia and death among
infants has been reported.
The described effects may have important
consequences for children in the early years of life. A child's immune
system is developing from birth to adolescence and requires a natural,
physiologic stimulation with antigens as well as inflammatory agents. Any
disturbances of this normal maturing process will increase the risk for
abnormal reactions to inhaled antigens and inflammagenic agents in the
environment.
The knowledge about health risks due to mold
exposure is not widespread and health authorities may not be aware of the
serious reactions mold exposure can provoke in some children. Individual
physicians may have difficulty handling the patients because of the lack
of recognition of the relationship between the often complex symptoms and
the indoor environment

The Anatomy Of Your
Respiratory System
Your lungs are amazing machines that give
your body all the oxygen it needs to live. Your lungs are made up of many
parts, and they are all important for your lungs to work right.
Nose and Mouth:
Your mouth and nose are very important, because they let air into your
body. Did you know that your nose and mouth are connected? Your nose
connects to the back of your mouth through two tubes. The air you breathe
in goes from your mouth and nose down to your trachea and into your lungs.
Your nose is really neat, because it is able to block some of the dirt and
germs in the air. Your nose has hair in it that can block some of the
stuff, but the most amazing part is the mucus that your nose makes. The
dirt and germs in the air get stuck in the mucus in your nose, and they
can't enter your lungs. When you blow your nose, you're getting rid of all
the bad germs and dirt that your nose stopped from getting into your body!
The Trachea:
Your trachea is the tube that connects your mouth and nose to your lungs.
You can also call it the windpipe. It is in the front of your neck, and is
very hard with tough rings around it. Feel the front of your neck. Can you
feel your trachea? Only air goes into your trachea. Food and drinks go
down a different tube called the esophagus. The esophagus is behind your
trachea, and you can't feel it from the outside of your neck. You have a
special flap of skin that covers the trachea when you're eating or
drinking. This little flap makes sure none of your food gets into your
lungs. That's why you can't swallow and breathe at the same time!
Sometimes the flap doesn't cover the trachea well enough, and stuff gets
into your lungs. It's probably happened to you. You start coughing a lot
because your lungs are trying to get the food out!
Bronchial Tubes:
When the air you breathe in
goes down your trachea, it comes to a fork in the road. These are the
bronchial tubes. One tube goes into your right lung, and the other goes
into your left lung. The bronchial tubes go into your lungs and keep
branching off into smaller and smaller tubes until the sacs at the end
called alveoli are reached. Your bronchial tubes not only bring the air
from your trachea to your alveoli, they also help clean your lungs. Your
bronchial tubes are covered with mucus, which sticks to dirt and germs
that get into your lungs. Next, millions of tiny hairs called
cilia act like tiny brooms to sweep out the bad stuff caught in the
mucus. Each cilium sweeps back and forth about ten times every second!
That's 36,000 every hour, 24 hours a day! They do this to keep your lungs
clean.
The Alveoli:
When air
enters your lungs, it goes through a maze of smaller and smaller tubes
until it reaches tiny sacs called alveoli. The sacs look like bunches of
grapes at the end of the bronchial tubes. The alveoli are where the oxygen
from the air enters your blood, and the carbon dioxide from your body goes
into the air. Alveoli are very tiny, but you have a lot of them in your
lungs. In fact, you have 300,000,000 alveoli in each lung. That's six
hundred million in total - and your body needs them all to get enough
oxygen into your blood!
The Diaphragm:
The diaphragm is a big
sheet-like muscle that's at the bottom of your chest cavity. The diaphragm
helps you get air in and out of your lungs by moving up and down. When
your diaphragm moves down, you breathe in. When your diaphragm moves up,
you breathe out! Try taking a really deep breath. Can you feel a
stretching feeling in your stomach? That's your diaphragm moving down as
you breathe in. Now try breathing out all the air in your lungs. Keep
pushing out air until no more comes out. The tightness you feel below your
chest is your diaphragm pushing up to get the air out! Without your
diaphragm, your lungs couldn't fill up with air or push old air out!
