10 years ago,
I got a phone call that
changed my life.
At the time, I was
cardiologist at UCLA,
specializing in cardiac
imaging techniques.
The call came from a veterinarian
at the Los Angeles Zoo.
An elderly female chimpanzee
had woken up with a facial droop
and the veterinarians were worried
that she had had a stroke.
They asked if I could
come to the zoo
and image the animal's heart
to look for a possible cardiac cause.
Now, to be clear, North American
North American zoos
are staffed
by highly qualified,
board-certified veterinarians
who take outstanding
care of animal patients.
But occasionally, they do reach into
the human medical community,
particularly for some
speciality consultation,
and I was one of the lucky physicians
who was invited to help.
I had a chance to rule out
a stroke in this chimpanzee
and make sure that this gorilla
didn't have a torn aorta,
evaluate this macaw
for a heart murmur,
make sure that this californian sea lion's
paracardium wasn't inflammed,
and in this picture, I'm listening
to the heart of a lion
after a lifesaving collaborative procedure
with veteranarians and physicians.
We drained 700 CCs of
fluid from the sack
in which this lion's
heart was contained.
And this procedure, which I have
done on many human patients,
was identical with the exception
of that paw and that tail.
Now most of the time, I was
working at the UCLA Medical Center
with physicians, discussing symptoms
and diagnoses and treatments
for my human patients.
But some of the time, I was
working at the Los Angeles Zoo
i was working at the
Los Angeles Zoo with veteranarians
discussing symptoms,
diagnoses and treatments
for their animal patients.
And occasionally, on
the very same day,
I went on rounds at the
UCLA Medical Center
and at the Los Angeles Zoo,
and here's what started coming
into very clear focus for me.
Physicians and veterinarians
were essentially taking care
of the same disorders in :their
animal and human patients
congestive heart failure, brain tumors,
lukemia, diabetes,
arthritis, ALS, breast cancer,
even psychiatric symptoms like depression,
anxiety, compulsions, eating disorders
and self injury.
Now, I've got a confession to make.
Even though I studied comparative
physiology and evolutionary biology,
as an undergrad,
I had even written my senior
thesis on darwinian theory,
learning about the
significant overlap
between the disorders of
animals and humans.
It came as a much needed
wake up call for me.
So I started wondering,
with all of these overlaps,
how was it that I had never
thought to ask a veterinarian,
or consult the veterinary literature,
for insights into one
of my human patients?
Why had I never, nor had any of my physician
friends and colleagues who I asked,
ever attended a veterinary conference?
For that matter, why was
any of this a surprise?
I mean look, every single physician
accepts some biological connection
between animals and humans.
Every medication that we prescribe
or that we've taken ourselves
or we've given to our families
has first been tested on an animal.
But there's something very different
about giving an animal a
medication or a human disease
and the animal developing
congestive heart failure
or diabetes or breats cancer on their own.
Now maybe some of the surprise
comes from the increasing
separation in our world
between the urban and the non-urban.
You know, we hear about
these city kids who
think that wool grows on trees
or that cheese comes from a plant.
Well today's human hospitals
are turning into increasingly
these gleaming cathedrals
of technology.
And this creates a psychological
distance between the human patients
who are being treated there
and animal patients who
are living in oceans
and farms and jungles.
But I think there's an even deeper reason.
Physicians and scientists, we accept,
intellectually that our species
homo sapien, is merely one species
no more unique or
special than any other.
But in our hearts, we don't
completely believe that.
I feel it myself when I'm
listening to Motzart
or looking at pictures of the
Mars Rover on my MacBook.
I feel that tug of
human exceptionalism,
even as I recognize the
scientifically isolating cost
of seeing ourselves as a
superior species apart.
Well, I'm trying these days.
When I see a human patient
now, I always ask,
"what do the animal doctors know
about this problem that I don't know?"
and "Might I be taking better
care of my human patient
if I saw them as a human
animal patient?"
Here are a few examples of the
kind of exciting connections
that this kind of t
thinking has led me to:
fear-induced heart failure.
Around the year 2000,
human cardiologists "discovered"
emotionally induced heart failure.
It was described in a gambling father
who had lost his life's savings
with the roll of a dice,
in a bride who had
been left at the alter.
But it turns out that this
"new human diagnosis"
was neither new, nor
was it uniquely human.
Veterinarians had been diagnosing,
treating, and even preventing
emotionally-induced
symptoms in animals,
ranging from monkeys to flamingos,
to deer to rabbits,
since the 1970s.
How many human lives
might have been saved
if this veterinary knowledge had
been put into the hands
of ER docs and cardiologists?
Self injury.
Some human patients harm themselves.
Some pluck out patches of hair.
Others actually cut themselves.
Some animal patients
also harm themselves.
There are birds that pluck out feathers.
There are stallions that repetitively
bite their flanks until they bleed.
but veterinarians have very specific
and very effective ways of treating and even preventing self injury
in their self injuring animals
shouldn't this veterinary knowledge be
put into the hands of psychotherapists
and parents and patients
struggling with self injury
post pardem depression and post pardem psychosis
sometimes,
soon after giving birth, some women
become depressed and sometimes
they become seriously depressed and sometimes
psychotic
they may neglect ehri newborn
and in some extreme cases,
even harm the child
Equine veteranarians also
know that a mare, soon
after giving birth
will neglect the foul
refusing to nurture it
and in some instances
kick the foul even to death.
But veterinarians have divised
an intervention to deal with
this foul rejection syndrom
that involves increasing oxytocin in the mare
oxytocin is the bonding hormone
and this leads to renewed interest
on the part of the mare in her foul
shouldn't this information
be put into the hands of OBGYNs
and family doctors and patients
who are struggling with post pardem depression
and psychosis?
well despite all of this promise
unfortunately, the gulf between our fields
remains large
to explain it, I'm afraid
I'm going to have to air
some dirty laundry
some physicians can be
real snobs
about doctors who are not MDs
I'm talking about dentists
and optomitrists and psychologists
but maybe especially, animal doctors
of course, most physicians
don't realize that it's harder
to get into vet school these days
than medical school
and that when we go to medical school,
we learn everything there is to konw
about one species, homo sapiens
but veterinarians need to learn
about health and disease
in mammals, amphibians,
reptiles, fish and birds
so, i don't blame the vets
for feeling annoyed by
my profession's condescension
and ignorance
but here's one from the vets
what do you call a veteranarian
who can only take care of one species?
a physician.
closing the gap has become a passions for me
and I'm doing this through programs
like darwin on rounds at UCLA
where we're bringing animal experts and
evolutionary biologists
and embedding them on our medical teams
with our interns and our residents
and through zoobiquity conferences
where we bring medical schools together
with veterinary schools
for collabortive discussions
of the shared diseases and disorders
of animal and human patients
at zoobiquity conferences,
participants learn how treating
breast cancer in a tiger can
help us better treat breast cancer in a kindergarten teacher
how understanding polycistic overies in a hole steen cow
can help us better take care
of a dance instructor with painful periods
and how better understanding the
treatment of separation anxiety
in a high strung shelty
can help a high strung child on his first days of school
in the united states and now internationally
at zoobiquity conferences
physicians and veteranarians check
their attitudes and their preconceptions at the door
and come together as colleagues
as peers,
as doctors
after all, we humans
are animals, too
and it's time for us physicians to embrace
our patients and our own animal natures
and join veterinarians
in a species-spannign approach to health
because it turns out
some of the best and most humanistic medicine
is being practiced by doctors whose
patients aren't human
and one of the best ways we can take care
of the human patient is by paying close
attention to how the other patients on the planet
live, grow, get sick and heal
Thank you.
(Applause).
