in dermatology we'll take a look at
those that are infectious in nature a
lot of repetition here with microbiology
as well as you can imagine begin our
topic by looking at folliculitis and I
want to make sure that by the time were
completed with our discussion that
you're quite clear as to what is it what
does it mean to have it for the colitis
and a41 called carbuncle and abscess sin
and so forth first thing comes
follicular unit and that basically is
going to have your hair right so think
about the hair that's coming out of your
skin and it's coming to a follicular
unit so in section of the hair follicle
is but what folliculitis is usually
refers to bacteria folliculitis usually
so that's where you want to go with this
and it's continuum of four uncles
carbuncles and abscissas you think of it
as such from henceforth you'll be in
good shape so say that you had an
infection of the silikal unit and it
wasn't properly managed and at some
point in time you can imagine that the
infection is going to get more severe
and with the continuum it's the for
uncle carbuncle end and apps information
on the skin which could then also
include the follicular unit are we clear
about the big picture of folliculitis
and if you take a look at the image that
has been provided and that I'm showing
you folliculitis where a hair follicle
unit has been infected the demographics
can occur at any age group can involve
terminal and the vilas hairs almost all
cases are caused by staph aureus that's
where your focus should be on cases in
the growing may be caused by what son as
your gram-negative type of bacteria a
degree of inflammation then dictates the
presentation the culture must be done so
that you could then look for your
particular organism management of
folliculitis oral antibiotics
such as a duck quacks ofin or a
selection consider culture for those
that are non responding and 25
occurrence in all comers anyway
incision and drainage for large
fluctuations imagine that now the silica
lettuce then goes on to become an
abscess and drainage is necessary
tacking and Mar civilization rarely
required so please do not choose this as
being an answer choice it would be a
distractor when it comes to folliculitis
differential diagnosis if it's acne
vulgaris remember at this would be a
condition that's taking place in your
Roberto age of population add narky use
your on the face and upper trunk only
and the fact that you've comedone as
being a feature of acne not of
folliculitis from the folliculitis
you're focusing upon the hair unit
another differential diagnosis here is
called perago nodule which is more or
less at neurodermatitis type of
excoriation not necessarily follicular
based and the fact that it's limited to
those areas that are reachable because
here you're thinking about this being a
neural derma kaduk type of condition a
differential
also known as your prickly key and by
that we mean malaria and with malaria
occlusion of your eccrine sweat duct not
referring to malaria but this military
exercise ation of sweat into your dermis
with inflammation and often the body
folds and areas in contact with the
occlusion
