Transcript
- 0:01I'm Holly Wayment and this is Pediatrics Now.
- 0:05And back on the show is Dr. Tess Barton. She's our pediatric infectious disease expert.
- 0:11Tess, thank you so much for being back on Pediatrics Now. Thanks for having me.
- 0:16So what about tics? Do you want to say anything there about tics?
- 0:21I know I went, I was on the East Coast and staying with one of my friends from
- 0:25Northwestern when I was in graduate school. She has two kids now.
- 0:28They have this beautiful backyard, all these gorgeous trees.
- 0:31But I got the sense they avoid going outside at all.
- 0:35Like even, she was so worried about ticks that we stayed inside at their house.
- 0:42Yes. So ticks also transmit some diseases. They can transmit some diseases.
- 0:49And some of those Those are also, you know, fairly serious diseases.
- 0:54The one that people always worry about is Lyme disease.
- 0:58Although we are lucky in Texas that we really don't have Lyme disease.
- 1:04Like it's quite rare here.
- 1:06We have the ticks and we have the deer, but that particular bacteria is not abundant here.
- 1:16We have its cousins. So we have other species of that that's not Lyme disease
- 1:25that can sometimes cause a fever illness or a rash illness.
- 1:30A variety of different things can be transmitted by ticks.
- 1:34And so, yes, if you've been in a wooded area or doing a lot of outdoor stuff,
- 1:41particularly in the country or in long grasses,
- 1:45It's a good idea to do a tick check after you've been and just make sure that
- 1:51you try to pick off any ticks that you see.
- 1:55And again, if you have household pets, if they're getting ticks because they
- 1:59go outside and stay there a little bit more frequently, that's usually a sign
- 2:04that you need to do some tick control.
- 2:06The good thing is that DEET actually repels both mosquitoes and ticks. Yes.
- 2:11So, and when you were talking about fleas, if we're doing flea prevention with
- 2:16our animals, though, it still could be in the grass because of other animals.
- 2:20It could be, but, you know, for animals, there's a variety of different flea
- 2:24preventions that are available.
- 2:25And the ones that, usually it's the ones that are by mouth, but even some of
- 2:29the drops, the way that they work is actually by sterilizing the fleas.
- 2:33And so if you do them for a month or two, you
- 2:36actually reduce the overall flea population on your
- 2:39property because even if there are fleas that are
- 2:42there they they become sterilized so
- 2:45of course you can't control the fleas that are
- 2:48on the raccoons or whatever but but you will actually decrease the flea infestation
- 2:52just by doing the like the oral flea treatments of course you can yeah and of
- 2:58course you can double that up with having you know a pest control company come
- 3:02out and spray your grass and and if you you know you spray the grass for a couple of months
- 3:07and do the flea control on your animals for a couple of months,
- 3:11you'll get rid of your fleas.
- 3:13And do that if you're noticing the bites on the ankles?
- 3:16Yeah. Yeah. Or if you notice that your animal has fleas.
- 3:20Do you want to talk about tests? What about the cousins of ticks or anything
- 3:24else in the next few minutes that we haven't covered? The cousins of Lyme disease?
- 3:30No. No. No, maybe, maybe what I'll, yes.
- 3:37So, so we, so Lyme disease is caused by a bacteria called Borrelia burgdorferi,
- 3:43and it is seen in other parts of the country very commonly.
- 3:46So in the Midwest and the Northeast are kind of the hotspots for Lyme disease.
- 3:51And, and it, it is, it's this sort of, you know, complex life cycle where that
- 3:57involves a deer and a tick and a human.
- 4:01And so And so we get it transmitted from the tick bite.
- 4:09As I mentioned, we don't really have endemic Lyme disease in Texas,
- 4:14but we do have other Borrelia's.
- 4:18And the most common one causes a thing that's called STARI, which is S-T-A-R-I,
- 4:26is the acronym, which is a Southern Tick Associated Rash Illness.
- 4:31So starry will freak everybody out because they'll think that they have Lyme disease.
- 4:37Because starry, where the tick bit you, you get that same ring around the bite
- 4:43that you get with Lyme disease.
- 4:47And so it looks like the rash of Lyme disease, but it doesn't usually have all
- 4:51of the systemic illness, the
- 4:54fever and the joint pains or the brain infection or any of those things.
- 4:58So it's usually a very limited illness, but it looks in the initial stage just
- 5:03like the Lyme disease rash.
- 5:06And one of the reasons that's important is because we don't have a test for that illness.
- 5:12But when somebody freaks out and they test for Lyme disease,
- 5:16the tests for those bacteria are cross-reactive.
- 5:19So if you've been exposed to one of these other Borrelia's that we do have here
- 5:28in Texas, your Lyme disease testing can be false positive.
- 5:33And it usually gets sort of sorted out with the sort of next round of testing
- 5:37that we do to be more specific.
- 5:40But people will waste a lot of their money and a lot of their time on chasing
- 5:46down an inappropriate test for Lyme disease.
- 5:53Well, and I remember as a child switching to chiggers. So I remember we did
- 5:57a lot of camping when I was a child.
- 5:59And I would worry about, because my parents would tell us about chiggers and
- 6:02I was so worried about getting them.
- 6:04And I remember getting them one time and it seemed like these like small bumps, a lot of them.
- 6:09And then if I'm remembering correctly, I think my parents put clear nail polish on them.
- 6:15Is that still a good, was that terrible to do? Or what do you say there? No, that's fine.
- 6:22Chiggers are also quite common and we do see chiggers in the sort of deep of summer.
- 6:27Chiggers are a mite. It also lives in the grass.
- 6:31They don't jump, they crawl. So again, they usually start on your feet.
- 6:36Or if you've been, you know, sitting in the grass to have your picnic or something,
- 6:40they may start on your behind or your back.
- 6:44Chiggers are similar, similar in some ways to scabies. So they actually burrow into your skin.
- 6:52And that's where they, yeah, so they basically just get right underneath your
- 6:55skin and they start sort of crawling around, looking for places to,
- 7:00you know, lay their eggs and make the babies.
- 7:03And they're almost microscopic. You can actually sort of see them.
- 7:09If you really look close, you can see these, you know, little teeny,
- 7:13teeny, tiny, you think they might be a tick, right?
- 7:15There's these little teeny, tiny, like, spots that crawl around.
- 7:19So and they're extremely extremely itchy
- 7:22and so yeah the treatment for chiggers traditionally
- 7:27is to you you can use you can use insecticide like treatments like creams that
- 7:33you would the same things that you might use for scabies but you can also smother
- 7:37them which is what the nail polish was about right so you basically trap them
- 7:42underneath you know where they are so that they They can't keep,
- 7:46you know, coming out and eating. And then they die because they're smothered.
- 7:51My grandma was a fan of using like ivory soap and Vaseline.
- 7:57And that's how, yeah, and that's how she cured the triggers.
- 8:00And the ivory soap is very drying.
- 8:02So I think it like clean, you know, you clean off, you know,
- 8:05you clean off any bacteria or whatever.
- 8:07You dry up the areas and then Vaseline sort of smothered them under the skin.
- 8:13But you can also use the same types of permethrin creams that you use for scabies
- 8:20on triggers and that will probably get rid of them more quickly than all these other remedies,
- 8:25well yes and and my mom who's a grandma now of course but a lot of these old-fashioned,
- 8:31recipes so to speak can be really helpful sounds like oh i love grandma medicine.
- 8:38Medicine on that grandma medicine yeah medicine
- 8:42is is is great you know like the
- 8:45the chicken soup and all those things they're they're they're valid yes we need
- 8:51that when we have a virus and i remember the giant when the smoke like playing
- 8:55in the backyard not the the smoke isn't the right word but the mosquito truck
- 8:59would come and spray the fog of mosquito repellent,
- 9:04I don't see that much anymore in the United States and the places I've been in.
- 9:08Yes, they do it. They do it when there's a West Nile.
- 9:13But they don't do it routinely anymore. But yeah. Because it's probably harmful
- 9:19for our lungs, I'm guessing.
- 9:22Yeah, very irritating. We did go inside. Yeah, that.
- 9:27So anything else, Tess? This has been so wonderful. Thank you for sharing your
- 9:31knowledge. Anything else you want the pediatric practitioner to know about if
- 9:35you see this particular sting or bite?
- 9:40No, I think, I mean, I think for the, for the pediatrician, probably just,
- 9:45you know, familiarizing yourself with the, with the patterns that can help you
- 9:51to distinguish from the bites.
- 9:53So, you know, like I mentioned, mosquito bites are on exposed areas.
- 9:57Bed bug bites are not on, like they, they will be on any area,
- 10:02including your face and under your clothes.
- 10:06Flea bites are you know usually if
- 10:09you pick them up in the grass they're on your ankles but
- 10:12they're also in exposed areas whereas chiggers
- 10:15chiggers actually they you know
- 10:18they they crawl somewhere and then they they actually like little
- 10:21tight spaces so they'll make they'll make
- 10:24their rash in the like in
- 10:27your sock line or your underwear line so there'll
- 10:30be like a line of of all the bites
- 10:33in those places and that's where chiggers will sort
- 10:36of congregate you know ticks
- 10:39ticks will crawl under your under your clothing and
- 10:43and so they can be anywhere including the scalp
- 10:46which most of these other things don't usually bite you on your scalp and and
- 10:51scabies you know most most pediatricians are super familiar with scabies but
- 10:58you know the scabies rash very typically between in the webbing of the fingers or the toes.
- 11:04And usually other people have it because it's quite contagious from person to person.
- 11:10And spiders...
- 11:12Usually have, because if it's a venomous spider, particularly,
- 11:16they will have a large reaction with that sort of blackening center where the
- 11:24tissues are getting destroyed by the spider venom.
- 11:27So there's, you know, there's little clues that you can use if the parents are
- 11:32asking, what bit my child, to try to get an answer.
- 11:37You may never know, but that, you know, Trying to do some pattern recognition
- 11:43can sometimes be the key.
- 11:45And for the venomous spider, if it's looking like that, what would you advise to do next?
- 11:51So interestingly, I mean, usually it's just wound care to keep things clean.
- 11:57If it is turning into a larger blackened thing or there's a lot of redness around
- 12:04it, they should go to the emergency room or the urgent care.
- 12:08And they may need antibiotics and they definitely may need some wound care as
- 12:15far as, you know, potentially debriding.
- 12:19Although mostly for spider bites, we say to leave it alone and not to do a lot of stuff to it.
- 12:25It will look terrible, but will eventually get better.
- 12:29The time to be worried is that both brown recluse bites are the ones that give
- 12:36you kind of a big, you know, blackened, horrible-looking lesion.
- 12:41But their venom can also get into the bloodstream and cause fever and other systemic signs.
- 12:50And those kids actually need to be seen because there is an anti-venom that's available.
- 12:55Available black widow and venomations there's not usually much of a impressive
- 13:00bite but they also can be in in the bloodstream and and cause you know up,
- 13:06paralysis and other neurologic symptoms
- 13:10so wow so if yeah so those
- 13:13are those are the those are the kind of bites that that
- 13:17you know should should warrant emergent attention and again with pattern recognition
- 13:23spider bites because they are bites and not stings they typically have their
- 13:28fang marks so if you see those two little dots as a fang mark then then that's
- 13:34a a clue that you're dealing with a spider bite.
- 13:36And then if there's a lot of swelling that's happening, then that could be urgent.
- 13:42Yes, yes. Swelling or definitely if you're having feelings of illness, right?
- 13:48So fever or dizziness or headaches or weakness or something like that,
- 13:53those are signs that the spiders not only caused a little local skin problem,
- 13:58but actually has injected its venom into your blood.
- 14:01Okay. And I get the sense that a lot of parents come in very worried.
- 14:06And it's, is it a lot though, like the, the saying in medicine,
- 14:10if you hear hoof beats, it's, you know, think horse.
- 14:13If it looks like a mosquito bite, it's probably a mosquito bite.
- 14:17Yes. Yes. Do you want to say anything just really quickly about hand, foot and mouth disease?
- 14:22I know that our listeners are seeing a lot of that. I know it has nothing to
- 14:25do with insects, right? Right. But it's about washing hands.
- 14:30Yeah, I mean, we have been seeing little outbreaks of hand, foot,
- 14:35and mouth, often associated with daycares.
- 14:40And it can look really variable.
- 14:44Some kids have stuff in the mouth and some don't. Some have spots,
- 14:49a few spots, and some have tons of spots.
- 14:52So there's sort of a wide variety of what that looks like.
- 14:57And i don't know what to say about it but yeah
- 15:01so i yeah so i think i think you
- 15:04know practicing the other you know i mean this is a virus that gets transmitted
- 15:07from person to person so all of the usual things that we do to prevent viruses
- 15:11from getting transmitted from person to person are the key to not getting hand
- 15:14foot mouth so yes good good hand washing if if a child has as hand, foot, mouth,
- 15:22they should not go to daycare.
- 15:24They should stay home with another caregiver so that they don't infect others around them.
- 15:30Don't go to the children's museum. Yeah, don't go to the children's museum. Exactly, exactly.
- 15:36So, yeah. And rest, or is there anything new treatment-wise?
- 15:42Yeah, it's just, you know, let it run its course of the treatment.
- 15:46Is there any type of insect that makes you worry the most? Is it a mosquito?
- 15:51So here, here in the United States, in Texas, the insect that actually worries
- 15:58me the most are, are fleas.
- 16:01And because they're, because they are the ones that are transmitting,
- 16:05you know, the, the most, the most significant illnesses, that's also fairly
- 16:09common. And, you know, traveling abroad, absolutely the mosquito, right?
- 16:15So if I'm in a place where dengue is a thing that occurs or malaria,
- 16:24then it becomes imperative to do the mosquito protection.
- 16:30Dr. Tess Barton, thank you so much for being back on Pediatrics Now today.
