- 0:42so my first tip is taking a good history
- 0:46this is so important it's fundamental
- 0:49it's the groundwork
- 0:50that gives you the best chance to be
- 0:53successful with the case
- 0:55but it's amazing how many people quickly
- 0:58run over it and don't pay any attention
- 0:59the dog comes or the cat comes into the
- 1:01room
- 1:02and immediately you want to touch the
- 1:04animal and find out what the problem is
- 1:07now many times in my career by taking a
- 1:10really good history
- 1:12i almost knew what the diagnosis was
- 1:14before i even looked
- 1:16at the dog or the cat i'll give you an
- 1:19example
- 1:21two young gps came in with a dog that
- 1:24very itchy had been seen by their own
- 1:27vets
- 1:28they couldn't come up with a diagnosis
- 1:30but by taking a careful history i found
- 1:32out that the gps were itching themselves
- 1:36by seeing where the dog was mainly
- 1:37itching i immediately made a diagnosis
- 1:40of scabies
- 1:41and was able to sort the dog's problem
- 1:43out very very quickly
- 1:47so histories are really important and i
- 1:49would encourage you to spend time
- 1:52finding out what the animal's diet is
- 1:55obviously its signalment its age
- 1:59looking at if there are other people in
- 2:01the house that are affected
- 2:04does the dog have diarrhoea as well this
- 2:07might be indicative of a food allergy
- 2:09with
- 2:09other skin signs all of these things are
- 2:13important
- 2:13spend time spend five to ten minutes
- 2:16taking a good history
- 2:18and it can save you a lot of time in the
- 2:20future
- 2:22my second tip concerns cats particularly
- 2:25allergic cats
- 2:27and it is amazing to me how often i i've
- 2:30seen a cat
- 2:31that obviously has an allergy of some
- 2:34description but when i
- 2:35ask about the flea treatment that's
- 2:38being given
- 2:38it's really not adequate and this can be
- 2:42sometimes because the vet has said i
- 2:45can't see any fleas
- 2:46therefore it can't be a flea allergy
- 2:50of course we know that cats that are fly
- 2:52allergic
- 2:53are very very effective at removing
- 2:56fleas from them
- 2:58by licking and swallowing them and in
- 3:00fact sometimes
- 3:01the best place to find a flea in a
- 3:05in an allergic cat is in the feces
- 3:09so i would encourage you always when you
- 3:12see
- 3:13a cat that is allergic even if you can
- 3:16see no fleas
- 3:17to consider that fleas are involved
- 3:19until
- 3:20proven otherwise and treat appropriately
- 3:26my third tip is around fleet treatment
- 3:32obviously over the last 25-30 years
- 3:34there's been an explosion
- 3:37in the number of products that we can
- 3:38use to treat fleas
- 3:40when i first qualified we had new van
- 3:43top the orange tin
- 3:45that hissed when you squirted it on the
- 3:47cat and the cat actually recognized
- 3:49the new van top and would be very
- 3:51difficult to catch
- 3:53it also killed pretty quickly but didn't
- 3:56last for very long
- 3:58so if two or three days later fleas came
- 4:01onto the cat again
- 4:02they wouldn't be killed by the spray now
- 4:06we have many products that act
- 4:08quickly but also last for a prolonged
- 4:10period
- 4:12and so i'd encourage you to go for one
- 4:14of the better
- 4:15veterinary recommended flea treatments
- 4:18obviously now there is the option to
- 4:20treat
- 4:21with spot on collars
- 4:25also with tablets and there are
- 4:28many many options out there but look at
- 4:31speed of kill
- 4:32and how long the product will last for
- 4:35and make sure that you follow the
- 4:36instructions
- 4:38of the manufacturers
- 4:43of course one of the major problems that
- 4:45we face
- 4:46and this is what i'm going to talk about
- 4:47with the fourth tip is
- 4:49antibiotic resistance i was reading a
- 4:52recent
- 4:53article about penguins in melbourne and
- 4:56one of the biologists has actually
- 4:58tested for antimicrobial resistance
- 5:01within the penguins who've never had
- 5:02antibiotics
- 5:04and she could find that there was
- 5:06antibiotic resistance
- 5:08to some of the bacteria that she found
- 5:10with them
- 5:11so this is a real global problem and i
- 5:13think we as vets need to take our
- 5:15responsibility seriously
- 5:18in large animal but also in small animal
- 5:20medicine
- 5:22and my key tip with antibiotics is that
- 5:25we use them appropriately
- 5:27very often i see people treating with
- 5:30a lower dose than is required for the
- 5:32weight of the animal
- 5:34and not for long enough so a dog comes
- 5:37in
- 5:38it's treated for seven days
- 5:41the skin looks better the vet or the
- 5:43client
- 5:44doesn't come back and the animal doesn't
- 5:48get the required three to four weeks
- 5:50that i think that you need to treat with
- 5:52to actually get rid of an infection
- 5:56obviously with mild infections we can
- 5:58try shampoos
- 5:59but otherwise we should not be afraid of
- 6:02treating
- 6:03adequately for a long enough period
- 6:06with the proper dose
- 6:12my fifth tip concerns using antibiotics
- 6:15and steroids concurrently
- 6:18i really don't recommend this when i
- 6:22was a young vet i experimented with this
- 6:25in a practice where
- 6:26i would just use antibiotics for three
- 6:28weeks whereas my colleagues often were
- 6:30using them for 10 days
- 6:32along with steroids of course after 10
- 6:35days the skin looked a lot better
- 6:37the steroids had reduced the
- 6:38inflammation and the antibiotics have
- 6:40probably killed a few bacteria
- 6:43but of course steroids
- 6:46will actually hide the real extent of
- 6:49the disease by removing that
- 6:51inflammation
- 6:52and will also make it very difficult for
- 6:54you to make a diagnosis
- 6:55during the diagnostic phase so i
- 6:59very very rarely if ever we'll use
- 7:01steroids and antibiotics together
- 7:04and yet i see this happening a lot in
- 7:06practice so i would encourage you
- 7:09to only use steroids after making a
- 7:12diagnosis
- 7:12or any of the anti-paritic
- 7:16drugs that are out there
- 7:19and then ideally not with steroids
- 7:22because i believe that that will make
- 7:25will often help to reduce immunity and
- 7:27and make it more difficult to control
- 7:30the pioderma in the first place so treat
- 7:33the pioderma
- 7:34see what you're left with treat
- 7:37concurrent
- 7:38potential allergies with food trialling
- 7:40and flea treatment
- 7:42and then quite often after three weeks
- 7:44you will find as i did that the dogs or
- 7:47that were only on antibiotics
- 7:50often did a lot better than those that
- 7:52were on antibiotics and steroids so
- 7:55think very carefully about using those
- 7:58two drugs together
- 7:59it is not good practice
- 8:04my sixth tip is about demodex
- 8:08we've made such strides over the last
- 8:10years
- 8:11in treating demodex again
- 8:14when qualifying it was a really really
- 8:16difficult disease to treat and in fact
- 8:18sometimes we had to
- 8:20put dogs to sleep that had demodex
- 8:23because they were so bad
- 8:25and that treatment has definitely
- 8:27developed over the years
- 8:30very much the revolution has happened
- 8:32with the um
- 8:34discovery and and the development of the
- 8:37isoxazoline
- 8:38so all of those drugs seem to have an
- 8:41activity
- 8:42against emoticosis and can be delivered
- 8:46you know on a monthly or or a quarterly
- 8:49basis
- 8:50and will give fantastic results i think
- 8:52you have to remember with demodex that
- 8:54there are two forms of demodex there's
- 8:56juvenile onset dermadecosis
- 8:59and there's adult-onset dermaticosis
- 9:03we think that juvenile onset
- 9:04dermatitosis is something to do with
- 9:06with a an immature immune system and
- 9:09sometimes if we can
- 9:10kick that immune system into place or as
- 9:13if the dog gets older it develops it it
- 9:15can sort
- 9:16the problem out itself whereas the adult
- 9:19onset dermaticosis usually means there's
- 9:21an underlying problem
- 9:23uh treatment with steroids for example
- 9:26could cause dermadicosis or perhaps
- 9:28a dog that is developing cushing's
- 9:30disease or hyperthyroidism so
- 9:33an older dog with dermadecosis needs to
- 9:36be
- 9:37really worked up to see what the
- 9:40underlying problem is
- 9:41but with a young dog then we we consider
- 9:45the dermatocosis to be the main problem
- 9:47and if we treat the
- 9:49and treat it adequately for long enough
- 9:52usually with the ice oxazolines now we
- 9:55will get
- 9:56really high treatment success
- 9:59prior to that of course we were using
- 10:01drugs like milbamycin
- 10:03ivamectin which were unlicensed and
- 10:07potentially
- 10:08could have side effects i think we all
- 10:11know about the potential for
- 10:13ivamectin to cause death in sheepdogs or
- 10:16in sheepdog crosses so it's a
- 10:18it's a drug that thankfully we can avoid
- 10:21now due to the great success of the ice
- 10:23oxazolines
- 10:25in the treatment of dermidicosis so
- 10:27please
- 10:28do use those as a first line
- 10:32but of course i've also seen studies
- 10:35where people are using
- 10:36isoxazolines with great results but then
- 10:40using the dam and messiah from that
- 10:43litter
- 10:44to continue breathing because they can
- 10:46sort the problem out
- 10:48with an ice oxazoline dose we know that
- 10:50this will lead to
- 10:52greater problems down the line so please
- 10:55also remember that when a dermadicosis
- 10:58litter is produced
- 11:00the diamond messiah should not be bred
- 11:02again
- 11:04my seventh tip is all about rabbits
- 11:07i think the key message with rabbits is
- 11:09please please don't use fipronil spray
- 11:11on them
- 11:12it can be a really serious issue
- 11:15uh rabbits have died because of being
- 11:18sprayed with fipronil
- 11:19very effective at obviously getting rid
- 11:21of their
- 11:23their fleas or their their mites or
- 11:25their lice
- 11:26but unfortunately can
- 11:30lead to really tragic consequences so
- 11:32don't use it there are
- 11:34other products out there like
- 11:35imidacloprid that you can use
- 11:38for fleas and obviously the other key
- 11:40point is always be checking your
- 11:42rabbit regularly particularly in the
- 11:44summer because we know
- 11:46how traumatic it can be for everybody
- 11:49including the rabbit when there is
- 11:51flight strike
- 11:52so carefully looking at a rabbit on a
- 11:55daily basis turning it over
- 11:57to to look for any wet patches
- 12:00but particularly with flea and
- 12:03ectoparasite treatment
- 12:05please don't use fipronil spray
- 12:12my eighth tip concerns testing for
- 12:15allergy we know that out there there are
- 12:17skin tests
- 12:19intradermal skin tests and blood tests
- 12:22which is the better one i think the
- 12:24first question we have to ask is why are
- 12:26we using the test
- 12:27i've seen very often that vets can use
- 12:30the test
- 12:31as a diagnostic tool to make a diagnosis
- 12:34of atp
- 12:36and actually atp is a disease entity
- 12:38that's diagnosed by
- 12:40ruling out the other issues
- 12:43so i think it's really important that we
- 12:45understand whether we use a skin test or
- 12:47a blood test that we're doing it
- 12:50to decide on what the dog
- 12:53or cat is specifically allergic to
- 12:56with a view to creating a vaccine
- 12:59there can be other reasons why i might
- 13:01skin test for example
- 13:03if it's a summer allergy and i know that
- 13:06by finding out
- 13:07which particular pollens the dog or cat
- 13:10is allergic to
- 13:11i can help the owner avoid those pollens
- 13:14so
- 13:15i always take the dog for a walk through
- 13:17this oak forest
- 13:18if the dog is allergic to oak let's
- 13:22change the walk pattern but it once
- 13:25we've
- 13:26made the diagnosis of atp and we're
- 13:28thinking about using
- 13:30intradermal vaccines to create
- 13:35a desensitized animal then i think there
- 13:38are
- 13:39measures and values in skin testing
- 13:42or in blood testing when i had my own
- 13:44practice i used
- 13:46r2 skip skin tests and i used hesca
- 13:50blood test that's because i thought they
- 13:52were the best on the market
- 13:55i think it's really important that
- 14:00you use the one that you you're best
- 14:02able to skin testing is very
- 14:04difficult to do if you're not doing a
- 14:06large number of them
- 14:07so i think it is a test that you
- 14:09probably leave to your dermatologist
- 14:12whereas a blood test using a good
- 14:14quality blood test that will
- 14:16measure properly and not create a lot of
- 14:19false positives
- 14:20is obviously open to many more vets
- 14:23in my own practice i often used both
- 14:26tests so that i had
- 14:27the most information i could get to then
- 14:32by looking at the history deciding
- 14:35which were most likely to be the most
- 14:37significant allergy so there's quite a
- 14:39lot of
- 14:39art and science in that creation of a
- 14:42vaccine and it's why i think that i
- 14:45often found this to be a very successful
- 14:47treatment whereas
- 14:49vets in general practice may find it
- 14:51less effective
- 14:53because of some of the subtle nuances
- 14:55that i've talked about there
- 14:56so both can be good
- 15:00you can use both together or you can go
- 15:04with skin
- 15:05or allergy testing i think the key is to
- 15:07use a test that you know
- 15:09is accurate and is not creating a lot of
- 15:12false positives or negatives
- 15:17my ninth tip is all about treating
- 15:20for long enough do you know often
- 15:25seeing referrals i was seeing seeing
- 15:27dogs and cats with quite chronic disease
- 15:29and the first thing that you almost have
- 15:31to do is set
- 15:32owner's expectations that this is going
- 15:34to be a long journey
- 15:36in some cases with allergy
- 15:40this is a diagnosis that you make that
- 15:42says
- 15:43we will control this dog or this cat
- 15:46symptoms and this will be a lifelong
- 15:49potential issue but with appropriate
- 15:52treatment we can actually keep things
- 15:53together
- 15:55obviously with things like deep
- 15:57piodermas it's really important to treat
- 16:01well beyond clinical cure so you
- 16:03continue with antibiotics particularly
- 16:05feet dermatocosis sometimes those deep
- 16:08piodermas that we could see could take
- 16:11several months to really get better
- 16:13because of the fibrosis
- 16:15getting the antibiotics into the deep
- 16:17tissue
- 16:18and actually having a clinical cure so i
- 16:22would encourage you with all treatments
- 16:23that
- 16:24this is also about compliance we often
- 16:26find that
- 16:28clients don't come back we don't follow
- 16:30them up they're lost to follow up we
- 16:32don't ring them to come in for more
- 16:33antibiotics
- 16:35and we end up again with a problem where
- 16:37we're not sorting it and of course we're
- 16:39more likely to create immunity
- 16:43you know antibiotic resistance and so on
- 16:46so
- 16:48do always think about treating for long
- 16:50enough with these conditions
- 16:53that they can be quite long lasting and
- 16:56will need aggressive treatment
- 17:02my tenth and final tip is all about
- 17:06using the right shampoo i am a real
- 17:09advocate of shampooing
- 17:11i think it can really help quicken the
- 17:14actual
- 17:15progression to cure but i think
- 17:18sometimes shampoos get a bad press
- 17:21because
- 17:22vets don't understand all of the
- 17:24different types of shampoos and can use
- 17:26the wrong
- 17:27shampoo at the wrong time with bad
- 17:29results
- 17:31and of course this puts them off using
- 17:33shampoos in the future
- 17:36with pioderma i think it's
- 17:39well recognized using an antibacterial
- 17:41shampoo
- 17:44will really help to quicken up
- 17:47the the cure and in fact in some cases
- 17:50particularly if you have an mrsp case a
- 17:53a methicillin-resistant staph assumed
- 17:55intermedius
- 17:56where you can't use antibiotics then
- 17:58chlorhexidine
- 18:00on its own sometimes can affect a cure
- 18:02so
- 18:03it's really good to understand how
- 18:07how shampoos can be used we also have
- 18:10the colloidal oatmeal shampoos that can
- 18:12be antipruritic and and can help to
- 18:16reduce itch particularly in those dogs
- 18:19that perhaps you're not
- 18:20giving any antiprotics to like steroids
- 18:24because you're about to test them for
- 18:26for skin allergy and so on
- 18:28so do look at shampoos as your friend
- 18:31if you've had a bad experience it's
- 18:34possibly been because you've
- 18:35you've used the wrong shampoo in the
- 18:37wrong place
- 18:39we know for example that with malassezia
- 18:42problems
- 18:42quite often shampooing once twice a week
- 18:46might be enough to keep that dog's itch
- 18:49which can be quite severe with
- 18:50malassezia
- 18:51under control so do think about
- 18:55shampoos as part of your treatment
- 18:57regime when treating
- 19:00dermatology cases
- 19:03now that you know about my top 10 tips
- 19:05in dermatology
