Our topic is impetigo
and impetigo is a
superficial skin infection.
It could be caused by
either strep or staph.
there are a couple of things that I
want to make sure that we go through
or that we’re clear
about in micro.
You have cellulitis, you have
erysipelas, and then you have impetigo.
Make sure that you’re clear about those
three presentations before we move on.
And all three could be caused by strep.
Cellulitis would be a
little bit deeper.
Erysipelas would be extremely rapid
caused by most likely strep A.
Fiery red, we call that St.
And here we have impetigo.
Either strep or staph.
Often in children and usually
on the central face.
And if you take a look
at the picture here,
you’ll notice that it’s
extremely distinctive and
characteristic for impetigo.
Honey-crusted lesions that we’re seeing
here specifically in the perioral area.
Now, if in fact that it is going
to be a strep A infection
and approximately, let’s
say four weeks later,
the patient, the child starts having, let’s
say, blood that appears in the urine.
This is the discussion
that we’ve had earlier
where if this impetigo is in fact being
caused by group A streptococci or pyogenes,
that approximately four weeks later,
we have now developed post
Are we clear?
Clinical appearance, no doubt.
And it cannot be diagnosed
with serologic test for strep.
Oral antibiotics and you have
topical mupirocin ointment.
Topic here is staph scalded
skin or scalded skin syndrome.
We have exfoliation caused by toxin
produced by Staph aureus infection.
So our topic is Staphylococcal
scalded skin syndrome.
We have a toxin of the Staph aureus which
is going to cause an issue in whom?
and unfortunately, most common with
infants and those with renal failure.
Scalded skin syndrome.
With staph, the management
with IV antibiotics,
either vanco or nafcillin,
and supportive care.
