WEBVTT 00:00:06.059 --> 00:00:09.800 Welcome to the bed. We'll go ahead and give you 00:00:09.800 --> 00:00:12.580 the story. This is all going to happen super 00:00:12.580 --> 00:00:47.250 fast. Welcome to the emergency room. Welcome 00:00:47.250 --> 00:00:50.270 back to the Deep Dive. We are shifting gears 00:00:50.270 --> 00:00:52.710 today. Usually we take a pretty broad look at 00:00:52.710 --> 00:00:55.759 a topic, you know, history, tech. culture, but 00:00:55.759 --> 00:00:58.259 today I feel like I've been handed a clipboard 00:00:58.259 --> 00:01:00.619 and a stethoscope. You basically have, yeah. 00:01:01.039 --> 00:01:02.979 Today isn't just about learning something, it's 00:01:02.979 --> 00:01:05.939 really about learning how to think like a clinician. 00:01:06.840 --> 00:01:09.640 We are diving into the, well, the very high stakes 00:01:09.640 --> 00:01:11.959 world of pediatric nursing. I have to admit, 00:01:12.060 --> 00:01:14.239 when I saw the stack of research you sent over, 00:01:14.379 --> 00:01:17.700 I mean textbooks, CDC protocols, vaccine inserts, 00:01:18.040 --> 00:01:20.359 I felt a little overwhelmed. It's dense stuff. 00:01:20.480 --> 00:01:23.299 It is. Who is this actually for? Is this just 00:01:23.299 --> 00:01:25.239 for, you know, the nursing students sweating 00:01:25.239 --> 00:01:26.939 over their boards, or should the rest of us stick 00:01:26.939 --> 00:01:28.579 around? Oh, it's for the students, absolutely. 00:01:28.700 --> 00:01:31.099 But it's also for parents. It's for the person 00:01:31.099 --> 00:01:33.060 who wants to understand why their doctor says 00:01:33.060 --> 00:01:36.560 no to antibiotics for a cold. Okay. It's for 00:01:36.560 --> 00:01:38.159 anyone who really wants to get the mechanics 00:01:38.159 --> 00:01:41.500 of how a virus can hijack the human body. Because 00:01:41.500 --> 00:01:44.420 the disease we're covering today, mumps, is practically 00:01:44.420 --> 00:01:46.840 the prototype for these kinds of viral infections. 00:01:47.099 --> 00:01:50.590 Mumps. The chipmunk disease. Exactly. It sounds 00:01:50.590 --> 00:01:54.010 quaint, doesn't it? Almost retro. But it is a 00:01:54.010 --> 00:01:56.310 perfect case study. It has these really distinct 00:01:56.310 --> 00:01:58.629 stages. It has specific targets in the body. 00:01:58.870 --> 00:02:01.409 And it has some genuinely terrifying safety traps 00:02:01.409 --> 00:02:03.769 that, if you miss them, can lead to tragedy. 00:02:04.530 --> 00:02:06.250 That is where I want to start. You mentioned 00:02:06.250 --> 00:02:08.509 a mission for this deep dive. We aren't just 00:02:08.509 --> 00:02:10.289 reading the textbook. We are doing something 00:02:10.289 --> 00:02:13.509 you called the Pareto 8020 review. Right. And 00:02:13.509 --> 00:02:16.280 this is a concept that saves lives and Honestly, 00:02:16.400 --> 00:02:19.300 it saves exam scores. The Pareto principle, you 00:02:19.300 --> 00:02:21.699 know, it says that 80 % of your results come 00:02:21.699 --> 00:02:24.240 from 20 % of your efforts. Okay, the 80 -20 rule. 00:02:24.479 --> 00:02:27.159 Exactly. In medicine, that means we cannot memorize 00:02:27.159 --> 00:02:29.719 every single line of the textbook. It's impossible. 00:02:29.979 --> 00:02:32.319 If you try to memorize, like, the molecular weight 00:02:32.319 --> 00:02:34.240 of the mumps virus, you are just wasting brain 00:02:34.240 --> 00:02:36.740 space. That's the nice -to -know stuff. Correct. 00:02:37.199 --> 00:02:39.229 We are hunting for the need -to -know. That's 00:02:39.229 --> 00:02:41.729 the 20 % of information that answers 80 % of 00:02:41.729 --> 00:02:44.930 the exam questions and critically prevents 80 00:02:44.930 --> 00:02:47.129 % of the bad outcomes at the bedside. We're looking 00:02:47.129 --> 00:02:49.449 for the red flags and the safety stops. I love 00:02:49.449 --> 00:02:51.370 that. I'll be the learner here. I'm going to 00:02:51.370 --> 00:02:52.889 ask the dumb questions so the listener doesn't 00:02:52.889 --> 00:02:55.789 have to. I want to understand the why behind 00:02:55.789 --> 00:02:58.650 these rules, not just memorizing the rules themselves. 00:02:58.789 --> 00:03:00.550 That is the best way to learn. It really is. 00:03:00.830 --> 00:03:02.229 If you understand the why, you don't have to 00:03:02.229 --> 00:03:04.539 just memorize the what. So let's look at the 00:03:04.539 --> 00:03:07.659 map. We're calling this section A the master 00:03:07.659 --> 00:03:11.199 80 -20 map. When you look at mumps through this 00:03:11.199 --> 00:03:14.000 80 -20 lens, what are we actually looking at? 00:03:14.120 --> 00:03:16.840 It's not just swollen cheeks, is it? No, not 00:03:16.840 --> 00:03:19.580 at all. Mumps is the prototype for what we call 00:03:19.580 --> 00:03:21.719 the viral glandular and respiratory pattern. 00:03:22.039 --> 00:03:24.560 That is your first mental hook. Glandular and 00:03:24.560 --> 00:03:26.800 respiratory? Yes. It enters through the breathing 00:03:26.800 --> 00:03:29.060 tubes, it hits the blood, and then it goes hunting. 00:03:29.979 --> 00:03:32.960 It's a hunter. It is. And on our map, there are 00:03:32.960 --> 00:03:36.099 four massive landmarks. These are the things 00:03:36.099 --> 00:03:38.680 that if you were a nurse, a parent, whatever, 00:03:39.500 --> 00:03:41.139 you cannot miss them. Okay, lay them out for 00:03:41.139 --> 00:03:43.759 me. What is landmark number one? Landmark one 00:03:43.759 --> 00:03:47.199 is the isolation window. This is pure... public 00:03:47.199 --> 00:03:49.460 health. You have to know exactly when that child 00:03:49.460 --> 00:03:52.419 is, well, radioactive, so to speak. If you get 00:03:52.419 --> 00:03:55.240 this wrong, you send a contagious kid back to 00:03:55.240 --> 00:03:57.639 school, and suddenly you don't have one case, 00:03:57.860 --> 00:04:00.199 you have an outbreak. Okay, so timing is everything. 00:04:00.259 --> 00:04:02.919 What's number two? Number two is the can't miss 00:04:02.919 --> 00:04:07.060 safety item. For mumps, and really for any viral 00:04:07.060 --> 00:04:10.460 thing in kids, it is the aspirin trap. I've heard 00:04:10.460 --> 00:04:12.319 this, don't give kids aspirin, but I've never 00:04:12.319 --> 00:04:14.180 really understood why. It's just a painkiller, 00:04:14.280 --> 00:04:17.019 right? We are gonna go deep on that because the 00:04:17.019 --> 00:04:20.019 mechanism is, well, it's frightening. It involves 00:04:20.019 --> 00:04:22.199 the liver and the brain basically shutting down. 00:04:22.199 --> 00:04:24.279 It's called Ray syndrome. Okay, you have my attention. 00:04:24.339 --> 00:04:27.019 That sounds incredibly high stakes. What is landmark 00:04:27.019 --> 00:04:29.399 number three? Number three is the anatomy of 00:04:29.399 --> 00:04:31.980 complications. This is where we move beyond the 00:04:31.980 --> 00:04:34.480 chipmunk cheeks. You need to know that the virus 00:04:34.480 --> 00:04:37.439 has a specific set of keys and it's looking for 00:04:37.439 --> 00:04:41.639 specific locks in the body. It unlocks the tests. 00:04:41.949 --> 00:04:44.990 the ovaries, the pancreas, and the lining of 00:04:44.990 --> 00:04:46.910 the brain. So it's a systemic invader. It goes 00:04:46.910 --> 00:04:50.389 everywhere. It does. And finally, number four 00:04:50.389 --> 00:04:53.430 is vaccine contraindications. We have a live 00:04:53.430 --> 00:04:57.250 vaccine, the MMR. But because it is live, there 00:04:57.250 --> 00:04:59.290 are certain people who absolutely cannot handle 00:04:59.290 --> 00:05:02.240 it. Giving it to the wrong person is a catastrophic 00:05:02.240 --> 00:05:04.939 error. So that's our roadmap. Isolation, aspirin 00:05:04.939 --> 00:05:07.300 safety, systemic targets, and vaccine rules. 00:05:07.420 --> 00:05:10.180 If we master those, we've got the 80%. You've 00:05:10.180 --> 00:05:11.699 got it. That's the core. All right. Let's move 00:05:11.699 --> 00:05:14.560 into section B. This is a deep dive lecture. 00:05:14.680 --> 00:05:16.740 Let's start with a definition. If I'm walking 00:05:16.740 --> 00:05:18.959 into a patient's room and I just need a one -liner 00:05:18.959 --> 00:05:22.180 to ground me, what is it? OK, here is the clinically 00:05:22.180 --> 00:05:25.379 accurate one -liner. Mumps is an acute viral 00:05:25.379 --> 00:05:28.259 illness caused by a paramexovirus. It primarily 00:05:28.259 --> 00:05:30.600 causes perititis. That's the swelling of the 00:05:30.600 --> 00:05:32.860 salivary glands. But it has the potential for 00:05:32.860 --> 00:05:35.759 really serious systemic complications like orchitis 00:05:35.759 --> 00:05:38.860 and meningitis. And it is preventable via a live 00:05:38.860 --> 00:05:42.519 attenuated vaccine. OK. Pyramixovirus. Keratitis. 00:05:42.839 --> 00:05:44.339 Systemic complications. Let's step that down. 00:05:44.500 --> 00:05:46.699 Talk to me about the pathology in plain English. 00:05:46.800 --> 00:05:48.339 You mentioned it enters through the respiratory 00:05:48.339 --> 00:05:51.240 tract. Walk me through the journey of that virus. 00:05:51.740 --> 00:05:55.360 OK. So imagine you are the virus. You were floating 00:05:55.360 --> 00:05:58.439 in a microscopic droplet of saliva. Maybe someone 00:05:58.439 --> 00:06:02.019 sneezed, or more likely, a kid shared a water 00:06:02.019 --> 00:06:06.259 bottle at soccer practice. Gross, but yeah, standard 00:06:06.259 --> 00:06:09.180 kid behavior. Extremely standard. So you enter 00:06:09.180 --> 00:06:12.060 the new host through the nose or mouth. You land 00:06:12.060 --> 00:06:14.360 in the nasopharynx, the back of the throat. This 00:06:14.360 --> 00:06:16.420 is your beach head. You start replicating the 00:06:16.420 --> 00:06:18.480 air in the local lymph nodes. You are building 00:06:18.480 --> 00:06:21.050 your army. And does the kid feel sick yet? At 00:06:21.050 --> 00:06:23.829 this point? Not really, no. This is the incubation 00:06:23.829 --> 00:06:26.810 period. And it takes a while, usually 16 to 18 00:06:26.810 --> 00:06:29.649 days on average. 16 to 18 days? That's a long 00:06:29.649 --> 00:06:32.350 time. It is a very long time. Wow, over two weeks. 00:06:32.629 --> 00:06:35.129 So the kid who sneezed on you is long gone from 00:06:35.129 --> 00:06:37.310 your memory. Exactly. And that's why tracking 00:06:37.310 --> 00:06:40.029 it's so hard. So after you've built your army 00:06:40.029 --> 00:06:41.930 in the lymph nodes, you launch the invasion, 00:06:42.430 --> 00:06:44.850 you enter the bloodstream. This is called veramia. 00:06:44.990 --> 00:06:47.889 Viramia, the virus is in the blood. Right. Now 00:06:47.889 --> 00:06:49.889 you are on the superhighway. And this is where 00:06:49.889 --> 00:06:53.470 the hunter thing comes in. Yes. The virus is 00:06:53.470 --> 00:06:55.810 circulating. It's surfing the blood. But it doesn't 00:06:55.810 --> 00:06:58.490 just attack random tissues. It ignores the muscles. 00:06:58.750 --> 00:07:02.329 It ignores the bones. It is specifically looking 00:07:02.329 --> 00:07:05.089 for glandular tissue. It has a chemical affinity 00:07:05.089 --> 00:07:07.110 for it. It's like a lock and key mechanism. So 00:07:07.110 --> 00:07:09.610 it finds the salivary glands first. Right. The 00:07:09.610 --> 00:07:11.610 parotid glands. That's the classic number one 00:07:11.610 --> 00:07:14.529 target. But it also finds the pancreas. It finds 00:07:14.529 --> 00:07:17.910 the testes in boys. It finds the ovaries in girls. 00:07:18.850 --> 00:07:21.149 And, frighteningly, it can cross the blood -brain 00:07:21.149 --> 00:07:24.170 barrier and find the meninges. That's the lining 00:07:24.170 --> 00:07:26.949 of the brain. It sounds incredibly precise for 00:07:26.949 --> 00:07:29.430 something that's just a microscopic germ. Evolution 00:07:29.430 --> 00:07:32.029 is a master engineer. It's very, very specific. 00:07:32.189 --> 00:07:34.509 Now, does this invasion look the same in everyone? 00:07:34.610 --> 00:07:36.970 If a toddler gets it versus a teenager, is it 00:07:36.970 --> 00:07:39.410 the same experience? No. And this is a massive 00:07:39.410 --> 00:07:42.350 exam point. Age matters a lot in young children. 00:07:42.589 --> 00:07:45.509 you know, infants, toddlers, preschoolers. Mumps 00:07:45.509 --> 00:07:47.569 is often what we call subclinical, or just really 00:07:47.569 --> 00:07:49.389 mild. They might seem a little fussy, maybe a 00:07:49.389 --> 00:07:51.370 little fever. They bounce back quickly. OK, so 00:07:51.370 --> 00:07:53.850 it's not a huge deal for them. Not usually. But 00:07:53.850 --> 00:07:56.209 once you hit puberty, the game completely changes. 00:07:56.649 --> 00:07:58.689 In adolescents and adults, the complications 00:07:58.689 --> 00:08:01.050 are much more frequent and much, much more severe. 00:08:01.350 --> 00:08:04.060 The virus just hits harder. Why is that? Well, 00:08:04.300 --> 00:08:07.540 it's partly the immune response being more robust 00:08:07.540 --> 00:08:10.579 and causing more inflammation, and partly the 00:08:10.579 --> 00:08:13.079 maturity of the tissues themselves. For example, 00:08:13.120 --> 00:08:15.360 orchitis, that inflammation of the testicles, 00:08:15.500 --> 00:08:17.680 it's extremely rare in a five -year -old. Right. 00:08:18.180 --> 00:08:21.540 But in a post -pubertal male, it happens in up 00:08:21.540 --> 00:08:24.379 to 30 % of unvaccinated cases. One in three. 00:08:24.500 --> 00:08:27.040 One in three. And that is a significant, painful, 00:08:27.240 --> 00:08:29.430 and psychologically distressing event. We are 00:08:29.430 --> 00:08:30.910 definitely going to talk more about that, because 00:08:30.910 --> 00:08:32.929 that sounds like an absolute nightmare for a 00:08:32.929 --> 00:08:35.509 teenage boy. But let's stick to the assessment 00:08:35.509 --> 00:08:38.009 for a second. I'm the nurse. A parent brings 00:08:38.009 --> 00:08:40.789 their child in. What am I actually seeing? What 00:08:40.789 --> 00:08:43.570 does parotitis look like in real life? You are 00:08:43.570 --> 00:08:45.809 looking at the jawline. The parotid gland sits 00:08:45.809 --> 00:08:48.190 right in front of the ear, and it sort of wraps 00:08:48.190 --> 00:08:50.970 around the angle of the jaw. When it swells, 00:08:51.090 --> 00:08:53.610 it just obliterates that sharp jawline definition. 00:08:53.830 --> 00:08:55.850 It pushes the earlobe upward and outward. So 00:08:55.850 --> 00:08:58.039 they look puffy. They look like they are storing 00:08:58.039 --> 00:09:00.779 nuts for winter, hence the chipmunk nickname. 00:09:01.259 --> 00:09:03.779 It's very accurate, but before you even see the 00:09:03.779 --> 00:09:06.139 swelling, there's a telltale sign. The child 00:09:06.139 --> 00:09:08.580 will often complain of an earache. An earache. 00:09:08.600 --> 00:09:10.799 So you'd think it was an ear infection. Exactly. 00:09:11.139 --> 00:09:13.539 And that's a common misdiagnosis at first because 00:09:13.539 --> 00:09:15.679 the gland is swelling and it's pushing against 00:09:15.679 --> 00:09:18.240 all the structures of the ear canal. So you look 00:09:18.240 --> 00:09:20.860 in the ear with your otoscope and the eardrum 00:09:20.860 --> 00:09:23.480 looks perfect. It's pearly gray, no infection. 00:09:24.009 --> 00:09:26.730 But the kid is screaming in pain. That's the 00:09:26.730 --> 00:09:29.110 clue. It's not the ear. It's the pressure on 00:09:29.110 --> 00:09:32.549 the ear. Precisely. And if you palpate, you know, 00:09:32.669 --> 00:09:34.129 gently touch the angle of the jaw, they will 00:09:34.129 --> 00:09:36.929 jump off the table. Chewing hurts. Talking hurts. 00:09:37.309 --> 00:09:39.690 Anything that stimulates saliva hurts. There's 00:09:39.690 --> 00:09:41.129 actually an old school trick called the pickle 00:09:41.129 --> 00:09:43.289 test. The pickle test? You're kidding! Not at 00:09:43.289 --> 00:09:44.889 all. You give the kid something sour, like a 00:09:44.889 --> 00:09:48.210 pickle or a drop of lemon juice. Sour foods stimulate 00:09:48.210 --> 00:09:51.129 a massive rush of saliva from the gland. If the 00:09:51.129 --> 00:09:53.730 gland is inflamed and the duct is blocked, that 00:09:53.730 --> 00:09:56.809 rush of fluid causes intense sharp pain. That 00:09:56.809 --> 00:09:59.509 sounds incredibly mean. We don't really do it 00:09:59.509 --> 00:10:01.769 anymore because it's cruel, but it illustrates 00:10:01.769 --> 00:10:04.350 the physiology perfectly. The gland is blocked 00:10:04.350 --> 00:10:06.490 and angry. Okay, so I've got a kid with a puffy 00:10:06.490 --> 00:10:10.389 jaw, ear pain, and he hates pickles. I'm worried 00:10:10.389 --> 00:10:13.409 about complications now. You mentioned the brain. 00:10:13.610 --> 00:10:16.590 What am I checking for there? You are doing a 00:10:16.590 --> 00:10:18.870 neurological assessment. You are checking for 00:10:18.870 --> 00:10:21.259 neutral rigidity. Fancy word. It just means a 00:10:21.259 --> 00:10:23.759 stiff neck. You ask them, can you touch your 00:10:23.759 --> 00:10:26.480 chin to your chest? If they can't, or if trying 00:10:26.480 --> 00:10:29.799 causes a shooting pain, that suggests the meninges 00:10:29.799 --> 00:10:32.179 are inflamed. OK. Then you check for a severe 00:10:32.179 --> 00:10:35.000 headache, and for photophobia, that's sensitivity 00:10:35.000 --> 00:10:37.159 to light. Are they squinting in a normally lit 00:10:37.159 --> 00:10:39.480 room? Those are the red flags for meningitis. 00:10:39.679 --> 00:10:42.059 OK. And now. Let's talk about the boys. He said 00:10:42.059 --> 00:10:45.299 30 % of post -pubertal males get orchitis. How 00:10:45.299 --> 00:10:48.460 do we assess that without completely traumatizing 00:10:48.460 --> 00:10:51.279 the poor kid? This requires high emotional intelligence. 00:10:51.399 --> 00:10:53.559 It really does. You are dealing with an adolescent 00:10:53.559 --> 00:10:55.919 male. He is already self -conscious about everything. 00:10:56.419 --> 00:10:58.799 Now his testicle is swelling to potentially double 00:10:58.799 --> 00:11:02.500 its size. And it is excruciatingly painful. Double 00:11:02.500 --> 00:11:06.919 the size? Yes. It can be very dramatic. And with 00:11:06.919 --> 00:11:10.000 that comes a huge fear. The fear of sterility. 00:11:10.139 --> 00:11:12.399 Well, is that a valid fear? I mean, if your testicle 00:11:12.399 --> 00:11:14.919 doubles in size and gets that inflamed, I would 00:11:14.919 --> 00:11:17.100 assume it's being destroyed. This is probably 00:11:17.100 --> 00:11:19.620 the biggest exam writer favorite and counseling 00:11:19.620 --> 00:11:23.000 trap in the entire topic. Listen closely. About 00:11:23.000 --> 00:11:26.080 50 % of the time, orchitis leads to testicular 00:11:26.080 --> 00:11:29.720 atrophy. Atrophy means shrinking. Yes. After 00:11:29.720 --> 00:11:31.740 the swelling goes down, the testicle will shrink 00:11:31.740 --> 00:11:34.720 and lose some of its mass. However, and you need 00:11:34.720 --> 00:11:37.620 to underline this mentally, sterility is actually 00:11:37.620 --> 00:11:40.850 rare. Wait, really? How can both of those be 00:11:40.850 --> 00:11:43.950 true? Yes. Because even if the affected testicle 00:11:43.950 --> 00:11:46.769 shrinks, it usually retains enough hormonal function 00:11:46.769 --> 00:11:49.929 and sperm production to be functional. Or, more 00:11:49.929 --> 00:11:52.509 commonly the other, unaffected testicle completely 00:11:52.509 --> 00:11:55.429 compensates. Total sterility from mumps or chytus 00:11:55.429 --> 00:11:57.830 is a very, very rare outcome. That is a massive 00:11:57.830 --> 00:11:59.950 distinction. It is everything. Imagine you are 00:11:59.950 --> 00:12:02.210 the nurse. You have a terrified 17 -year -old 00:12:02.210 --> 00:12:04.919 and his terrified father in a room. If you imply 00:12:04.919 --> 00:12:07.080 that he's going to be infertile, you are causing 00:12:07.080 --> 00:12:09.200 serious psychological damage that just isn't 00:12:09.200 --> 00:12:11.100 supported by the evidence. So what's the right 00:12:11.100 --> 00:12:12.960 way to say it? You have to explain it clearly. 00:12:13.240 --> 00:12:15.559 You say, I know this is scary and very painful. 00:12:15.840 --> 00:12:18.220 The swelling will go down. It is possible that 00:12:18.220 --> 00:12:21.039 it might get smaller afterwards, but you will 00:12:21.039 --> 00:12:23.259 very likely still be able to have children in 00:12:23.259 --> 00:12:25.519 the future. That is the need to know right there. 00:12:25.779 --> 00:12:28.580 Atrophy does not equal sterility. Precisely. 00:12:28.779 --> 00:12:31.220 Write it in stone. OK, let's talk about interventions. 00:12:31.460 --> 00:12:34.559 We know what it is. What do we do? Do we give 00:12:34.559 --> 00:12:37.440 antibiotics? Absolutely not. And if you see an 00:12:37.440 --> 00:12:39.620 exam question listing amoxicillin as an option, 00:12:40.139 --> 00:12:42.620 run away from it. It is a virus. Antibiotics 00:12:42.620 --> 00:12:44.740 do nothing but kill the good bacteria in your 00:12:44.740 --> 00:12:47.879 gut. So we are helpless? No, we are supportive. 00:12:48.440 --> 00:12:50.659 We treat the symptoms. We manage the pain and 00:12:50.659 --> 00:12:53.000 the fever. And this brings us to the biggest 00:12:53.000 --> 00:12:56.539 safety trap of the entire deep dive. The aspirin 00:12:56.539 --> 00:12:59.259 trap. Yes, you warned us about this. Why can't 00:12:59.259 --> 00:13:01.779 I give a 10 -year -old with a fever some aspirin? 00:13:01.899 --> 00:13:04.840 It works for me. Because you are an adult. Your 00:13:04.840 --> 00:13:07.500 liver works differently. In children and teenagers, 00:13:07.899 --> 00:13:10.440 if you introduce aspirin, the chemical name is 00:13:10.440 --> 00:13:13.820 salicylates, during a viral infection like influenza, 00:13:14.399 --> 00:13:17.960 chickenpox, or mumps, you can trigger a metabolic 00:13:17.960 --> 00:13:20.409 disaster called race syndrome. Break down the 00:13:20.409 --> 00:13:22.429 mechanism for me. What actually happens? The 00:13:22.429 --> 00:13:24.950 aspirin, combined with the stress from the virus, 00:13:25.570 --> 00:13:28.049 damages the mitochondria inside the liver cells. 00:13:28.850 --> 00:13:30.529 The mitochondria are the little power plants 00:13:30.529 --> 00:13:33.590 of the cell. When they fail, the liver stops 00:13:33.590 --> 00:13:36.309 doing its job. It stops processing toxins. Okay, 00:13:36.350 --> 00:13:38.789 that sounds really bad. It gets much worse. A 00:13:38.789 --> 00:13:40.970 toxin called ammonia begins to build up in the 00:13:40.970 --> 00:13:43.110 blood because the liver isn't filtering it out. 00:13:43.610 --> 00:13:46.620 That ammonia travels to the brain. and it causes 00:13:46.620 --> 00:13:48.960 cerebral edema brain swelling. So you go from 00:13:48.960 --> 00:13:51.679 a common fever to brain swelling. Rapidly. The 00:13:51.679 --> 00:13:53.840 child will start vomiting uncontrollably, become 00:13:53.840 --> 00:13:56.399 confused, then aggressive, then lethargic, and 00:13:56.399 --> 00:13:58.480 then they can slip into a coma. It has a very 00:13:58.480 --> 00:14:00.840 high mortality rate. That is absolutely terrifying. 00:14:01.059 --> 00:14:03.679 It is. And that is why we have a hard and fast 00:14:03.679 --> 00:14:07.620 rule in pediatrics. No aspirin. Use acetaminophen, 00:14:07.759 --> 00:14:10.519 which is Tylenol, or ibuprofen, which is Motrin. 00:14:11.039 --> 00:14:13.279 Never aspirin. And you have to watch out for 00:14:13.279 --> 00:14:15.139 things like Pepto -Bismol. because that contains 00:14:15.139 --> 00:14:17.539 cellulose lids, too. Peptobismal. I would not 00:14:17.539 --> 00:14:19.460 have even thought of that. That's a classic hidden 00:14:19.460 --> 00:14:21.860 trap. A parent trying to treat an upset stomach 00:14:21.860 --> 00:14:25.120 accidentally causes a huge problem. OK, so supportive 00:14:25.120 --> 00:14:29.240 care, pain meds, but not aspirin, hydration. 00:14:29.600 --> 00:14:31.700 What about ice packs for the jaw? Or warm packs? 00:14:32.000 --> 00:14:34.220 Honestly, whatever feels better for the child, 00:14:34.779 --> 00:14:37.519 there is no hard rule there. It's about comfort. 00:14:37.720 --> 00:14:40.779 Now, let's go back to landmark number one, isolation. 00:14:41.159 --> 00:14:43.879 The kid is sick. Can they go to school? Absolutely 00:14:43.879 --> 00:14:47.379 not. This is a strict public health rule. A person 00:14:47.379 --> 00:14:49.480 with mumps is contagious from about two days 00:14:49.480 --> 00:14:52.240 before the swelling stops until five days after 00:14:52.240 --> 00:14:54.039 the swelling starts. But we don't know they are 00:14:54.039 --> 00:14:56.559 sick two days before. Right. And that's the tricky 00:14:56.559 --> 00:14:58.879 part. That's why outbreaks spread so easily. 00:14:59.379 --> 00:15:01.600 But once you identify the swelling, the parotitis, 00:15:02.000 --> 00:15:05.039 the clog starts. You must isolate them for five 00:15:05.039 --> 00:15:07.440 days from the onset of that swelling. Why five 00:15:07.440 --> 00:15:09.759 days? Why not seven or ten? Because the viral 00:15:09.759 --> 00:15:12.419 load in the saliva drops off precipitously after 00:15:12.419 --> 00:15:15.830 day five. The risk of transmission becomes negligible 00:15:15.830 --> 00:15:19.009 at that point. So five days is the scientifically 00:15:19.009 --> 00:15:21.570 determined balance point between public safety 00:15:21.570 --> 00:15:24.110 and getting the kid back to their life. Got it. 00:15:24.149 --> 00:15:26.330 Five days. Write that down. And droplet precautions. 00:15:27.429 --> 00:15:29.350 If you are the nurse in the hospital, you wear 00:15:29.350 --> 00:15:32.450 a mask. The virus travels in spit and sneezes. 00:15:32.850 --> 00:15:36.159 Let's pivot to Section B, Part 5. Development. 00:15:36.419 --> 00:15:38.700 We always talk about how these diseases impact 00:15:38.700 --> 00:15:41.779 development. How does mumps mess with the child's 00:15:41.779 --> 00:15:43.600 milestones? Well, let's start with the toddler. 00:15:43.759 --> 00:15:45.860 We mentioned hearing loss is a complication. 00:15:45.919 --> 00:15:48.679 Right. From the meningitis or encephalitis. Exactly. 00:15:49.080 --> 00:15:51.340 The mumps virus can directly damage the hair 00:15:51.340 --> 00:15:54.100 cells in the cochlea of the inner ear. It can 00:15:54.100 --> 00:15:57.259 cause permanent unilateral that means one -sided 00:15:57.259 --> 00:16:00.220 deafness. That's huge for a toddler who is just 00:16:00.220 --> 00:16:02.320 learning to speak. It is a massive deal. If you 00:16:02.320 --> 00:16:04.179 have a two -year -old who recovers from mumps 00:16:04.179 --> 00:16:06.419 and suddenly they start responding when you call 00:16:06.419 --> 00:16:08.600 them from the other room or their speech starts 00:16:08.600 --> 00:16:11.840 to slur or even regress, that is a massive red 00:16:11.840 --> 00:16:13.679 flag. You need a hearing screen immediately. 00:16:14.000 --> 00:16:16.080 And for the adolescent, what's the developmental 00:16:16.080 --> 00:16:19.379 impact there? It's social and emotional. First, 00:16:19.659 --> 00:16:21.860 missing five plus days of school is stressful 00:16:21.860 --> 00:16:25.259 for a teenager. But the body image issues associated 00:16:25.259 --> 00:16:28.460 with orchitis are profound. Developmentally, 00:16:28.700 --> 00:16:31.600 teenagers are in Erickson's stage of identity 00:16:31.600 --> 00:16:33.840 versus role confusion. They just want to fit 00:16:33.840 --> 00:16:36.220 in. They want to fit in more than anything. Having 00:16:36.220 --> 00:16:38.320 a medical condition that affects their genitals 00:16:38.320 --> 00:16:41.399 makes them feel other or broken at a time when 00:16:41.399 --> 00:16:43.440 they are most vulnerable. So the nurse isn't 00:16:43.440 --> 00:16:45.299 just treating the swelling, they are treating 00:16:45.299 --> 00:16:48.879 the teenage ego. You absolutely are. Privacy 00:16:48.879 --> 00:16:51.659 is paramount. You do not discuss his testicular 00:16:51.659 --> 00:16:53.279 swelling in the hallway where his classmates 00:16:53.279 --> 00:16:55.960 might hear. You create a safe space for him to 00:16:55.960 --> 00:16:58.120 ask embarrassing questions. Good advice. Let's 00:16:58.120 --> 00:17:01.120 move to section C, the vaccine. This is our main 00:17:01.120 --> 00:17:04.400 weapon against mumps, the MMR. Measles, mumps, 00:17:04.559 --> 00:17:06.000 rubella. And there's a version with chickenpox 00:17:06.000 --> 00:17:09.920 too, right? MMRV. Yes. And this is a really important 00:17:09.920 --> 00:17:12.259 nuance that pediatric nurses need to know. We 00:17:12.259 --> 00:17:14.960 have two ways to give these shots to a baby at 00:17:14.960 --> 00:17:17.619 their one -year checkup. We can give MMR and 00:17:17.619 --> 00:17:20.539 varicella as two separate pokes, or we can combine 00:17:20.539 --> 00:17:23.220 them into one shot, the MMRV. One shot sounds 00:17:23.220 --> 00:17:25.279 better. Less crying, right? You would think so. 00:17:25.599 --> 00:17:28.180 And parents often prefer it. But the data shows 00:17:28.180 --> 00:17:31.099 something very interesting in toddlers. specifically 00:17:31.099 --> 00:17:34.299 in that 12 to 23 month age group. The combined 00:17:34.299 --> 00:17:38.000 MMRV shot has a slightly higher risk of febrile 00:17:38.000 --> 00:17:41.279 seizures. Seizures caused by fever. Yes. The 00:17:41.279 --> 00:17:43.700 immune response is so robust to the four viruses 00:17:43.700 --> 00:17:46.660 at once that the fever can spike higher and faster 00:17:46.660 --> 00:17:48.859 than with separate shots and that can trigger 00:17:48.859 --> 00:17:51.319 a simple febrile seizure in susceptible toddlers. 00:17:51.480 --> 00:17:54.519 The risk is about 1 in 2 ,300 kids. That's small, 00:17:54.539 --> 00:17:57.240 but it's not zero. Correct. So the official recommendation 00:17:57.240 --> 00:17:59.579 from the CDC is this. For the first dose, the 00:17:59.579 --> 00:18:01.380 one -year -old dose, it's preferable to give 00:18:01.380 --> 00:18:03.920 them separately. MMR in one leg, varicella in 00:18:03.920 --> 00:18:06.180 the other. It lowers that fever risk. And for 00:18:06.180 --> 00:18:08.180 the older kid, the four -year -old getting their 00:18:08.180 --> 00:18:11.119 kindergarten shots. By age four, the risk of 00:18:11.119 --> 00:18:14.160 febrile seizures drops to almost zero. So for 00:18:14.160 --> 00:18:17.299 the second dose, you can absolutely use the MMRV 00:18:17.299 --> 00:18:21.049 combo. Save them a poke. That is such a specific 00:18:21.049 --> 00:18:23.789 high -yield detail. Separate for baby, combo 00:18:23.789 --> 00:18:26.029 for pre -K. Exactly the kind of thing they'd 00:18:26.029 --> 00:18:29.369 ask on an exam. Now, contraindications. Who absolutely 00:18:29.369 --> 00:18:32.049 cannot get this vaccine? Remember, it is a live, 00:18:32.250 --> 00:18:35.809 attenuated virus. That's key. It means the virus 00:18:35.809 --> 00:18:39.190 in the shot is alive, just significantly weakened. 00:18:39.450 --> 00:18:41.289 It has to replicate a little bit in your body 00:18:41.289 --> 00:18:43.349 to teach your immune system what to do. So if 00:18:43.349 --> 00:18:46.480 your immune system is... Well, garbage. The vaccine 00:18:46.480 --> 00:18:48.660 can actually make you sick. The weakened virus 00:18:48.660 --> 00:18:52.180 can become a real infection. So severe immunocompromise 00:18:52.180 --> 00:18:54.900 is a hard stop. We're talking about chemotherapy 00:18:54.900 --> 00:18:57.180 patients, children with advanced HIV who have 00:18:57.180 --> 00:19:00.420 very low CD4 counts, or kids on high -dose steroids 00:19:00.420 --> 00:19:03.279 for a long time. How about pregnancy? Pregnancy 00:19:03.279 --> 00:19:06.170 is an absolute contraindication. Theoretically, 00:19:06.349 --> 00:19:08.250 the rubella component could harm the developing 00:19:08.250 --> 00:19:11.130 fetus. So we tell women to avoid getting pregnant 00:19:11.130 --> 00:19:13.130 for at least four weeks after they get the vaccine. 00:19:13.269 --> 00:19:15.029 And if they are already pregnant and need the 00:19:15.029 --> 00:19:17.190 vaccine? They have to wait until after they deliver 00:19:17.190 --> 00:19:19.769 to get vaccinated. No exceptions. OK. I have 00:19:19.769 --> 00:19:22.809 to ask about the controversy. We can't talk about 00:19:22.809 --> 00:19:25.130 MMR without talking about autism. No, we have 00:19:25.130 --> 00:19:28.309 to address it. Every nurse, every provider will 00:19:28.309 --> 00:19:30.730 face this question from a parent. And you need 00:19:30.730 --> 00:19:33.490 to have a script ready that is compassionate, 00:19:33.740 --> 00:19:36.579 but firm on the science. What is that script? 00:19:36.880 --> 00:19:39.480 The script is something like I understand you 00:19:39.480 --> 00:19:41.710 are trying to protect your child That is my goal, 00:19:42.009 --> 00:19:44.230 too. I can tell you that this question has been 00:19:44.230 --> 00:19:46.329 studied more than almost any other medical question 00:19:46.329 --> 00:19:48.970 in history. Millions of children across multiple 00:19:48.970 --> 00:19:50.910 countries have been tracked. The National Academy 00:19:50.910 --> 00:19:53.769 of Medicine, the CDC, the World Health Organization, 00:19:54.109 --> 00:19:56.390 they have all concluded there is no link between 00:19:56.390 --> 00:19:59.470 the MMR vaccine and autism. The original study 00:19:59.470 --> 00:20:01.589 from the 90s that suggested a link was found 00:20:01.589 --> 00:20:04.349 to be fraudulent and the doctor lost his license. 00:20:04.569 --> 00:20:07.369 Clear, definitive, but respectful. You have to 00:20:07.369 --> 00:20:09.869 be. Shaming a parent never changes their mind. 00:20:10.079 --> 00:20:12.980 But you cannot waver on the science. The science 00:20:12.980 --> 00:20:15.359 is settled. One more specific trap regarding 00:20:15.359 --> 00:20:19.440 the vaccine. Blood products. Ah, yes. This is 00:20:19.440 --> 00:20:22.440 the antibody interference rule. It's a bit tricky. 00:20:22.940 --> 00:20:25.259 If a child has received a blood transfusion, 00:20:25.440 --> 00:20:28.359 or IVG, that's intravenous immunoglobulin recently, 00:20:29.119 --> 00:20:31.400 their blood is full of someone else's antibodies. 00:20:31.619 --> 00:20:33.619 Okay, so they have passive immunity. Exactly. 00:20:33.940 --> 00:20:36.509 And if you give a live vaccine... While those 00:20:36.509 --> 00:20:38.930 donor antibodies are still floating around, those 00:20:38.930 --> 00:20:41.769 antibodies will attack the vaccine virus and 00:20:41.769 --> 00:20:44.250 kill it before the child's own immune system 00:20:44.250 --> 00:20:46.690 can learn from it. It effectively neutralizes 00:20:46.690 --> 00:20:49.240 the vaccine. It completely neutralizes it. So 00:20:49.240 --> 00:20:51.119 the vaccine won't work, you have to wait. Sometimes 00:20:51.119 --> 00:20:52.980 it's three months, sometimes it's up to 11 months, 00:20:53.079 --> 00:20:54.519 depending on what blood product they got and 00:20:54.519 --> 00:20:56.980 at what dose. That is a great deeper level check. 00:20:57.339 --> 00:21:00.059 Have you had a blood transfusion lately before 00:21:00.059 --> 00:21:02.359 giving the shot? It's a standard screening question 00:21:02.359 --> 00:21:05.039 on the vaccine forms for that exact reason. Okay, 00:21:05.200 --> 00:21:07.380 section D, cross -linking. We are in the differential 00:21:07.380 --> 00:21:10.180 diagnosis phase. A kid comes in with a swollen 00:21:10.180 --> 00:21:13.559 jaw. Is it always mumps? No. Definitely not. 00:21:13.700 --> 00:21:15.779 And this is where good clinical detective work 00:21:15.779 --> 00:21:19.180 comes in. Parotitis, the swelling, can be caused 00:21:19.180 --> 00:21:21.180 by a bunch of other things. Like what? Epstein 00:21:21.180 --> 00:21:24.460 -Barr virus, which causes mono, can do it. Influenza 00:21:24.460 --> 00:21:27.319 A can do it. Even HIV, in some cases, can present 00:21:27.319 --> 00:21:29.700 with parotid swelling. What about non -viral 00:21:29.700 --> 00:21:32.359 things? Absolutely. You can have salithiasis. 00:21:32.480 --> 00:21:35.299 Sal what? Salithiasis. It's a salivary duct stone, 00:21:35.779 --> 00:21:37.940 just like a kidney stone, but it forms in the 00:21:37.940 --> 00:21:40.700 saliva duct. It blocks the flow of saliva, and 00:21:40.700 --> 00:21:42.900 the gland swells up behind the blockage. How 00:21:42.900 --> 00:21:44.599 do you tell the difference between a stone and 00:21:44.599 --> 00:21:48.019 mumps? A stone is usually unilateral, so just 00:21:48.019 --> 00:21:50.460 one side. And the pain and swelling often get 00:21:50.460 --> 00:21:52.759 much worse right when they start eating, because 00:21:52.759 --> 00:21:54.700 that's when the gland is trying to secrete saliva. 00:21:55.299 --> 00:21:57.339 Mumps is viral, so you usually have that fever 00:21:57.339 --> 00:22:00.920 and body ache prodrome. Also, mumps is epidemic. 00:22:01.339 --> 00:22:03.640 If five kids in the same third grade class have 00:22:03.640 --> 00:22:06.839 swollen cheeks, it's not stone. It's mumps. Right. 00:22:07.059 --> 00:22:08.859 Another interesting differential, especially 00:22:08.859 --> 00:22:12.420 in adolescence, is bulimia nervosa. Really? An 00:22:12.420 --> 00:22:14.839 eating disorder? How does that cause it? Yes. 00:22:15.579 --> 00:22:17.700 The chronic vomiting forces stomach acid into 00:22:17.700 --> 00:22:20.680 the mouth, which constantly irritates the parotid 00:22:20.680 --> 00:22:25.019 glands. Over time, you can get bilateral prodded 00:22:25.019 --> 00:22:27.019 hypertrophy. That's swelling in patients with 00:22:27.019 --> 00:22:29.660 bulimia. So if you see a teenage girl with puffy 00:22:29.660 --> 00:22:32.539 cheeks, but no fever, and you notice worn down 00:22:32.539 --> 00:22:34.900 tooth enamel from the acid. You need to be thinking 00:22:34.900 --> 00:22:38.039 about bulimia, not mumps. Wow. That is a crucial 00:22:38.039 --> 00:22:40.720 need to know. It is. Because it changes the entire 00:22:40.720 --> 00:22:43.000 care plan. You're not looking for a virus. You're 00:22:43.000 --> 00:22:44.660 looking at a serious mental health condition. 00:22:45.180 --> 00:22:47.220 Let's talk about breakthrough cases. We hear 00:22:47.220 --> 00:22:49.640 about these outbreaks on college campuses all 00:22:49.640 --> 00:22:52.279 the time. mumps outbreak at State University, 00:22:52.900 --> 00:22:54.960 and almost all the kids are vaccinated. Does 00:22:54.960 --> 00:22:57.720 that mean the vaccine is trash? No, but it does 00:22:57.720 --> 00:22:59.599 mean the vaccine isn't a magical force field. 00:22:59.779 --> 00:23:02.460 The MMR is about 88 % effective against mumps 00:23:02.460 --> 00:23:05.420 after two doses. That is very good, but it's 00:23:05.420 --> 00:23:08.380 not 100%. So 12 out of every 100 people are still 00:23:08.380 --> 00:23:11.740 vulnerable? Roughly. And we also know that immunity 00:23:11.740 --> 00:23:14.460 can wane over time. So if you got your last shot 00:23:14.460 --> 00:23:17.380 at age five, by the time you're 20, your antibody 00:23:17.380 --> 00:23:20.099 levels might be lower. Combine that with a college 00:23:20.099 --> 00:23:22.960 dorm. I mean, kids living on top of each other, 00:23:23.099 --> 00:23:25.579 sharing drinks, stressed out, not sleeping. And 00:23:25.579 --> 00:23:27.880 the dose of viral exposure can be high enough 00:23:27.880 --> 00:23:30.920 to overwhelm that waning immunity. But, and this 00:23:30.920 --> 00:23:32.980 is the key question, if a vaccinated kid gets 00:23:32.980 --> 00:23:36.119 it, is it the same disease? No. And this is the 00:23:36.119 --> 00:23:38.880 most important takeaway for parents. Breakthrough 00:23:38.880 --> 00:23:41.660 cases are consistently and significantly milder. 00:23:41.740 --> 00:23:44.420 They have less fever, the swelling lasts for 00:23:44.420 --> 00:23:46.619 a shorter time, and most importantly, they have 00:23:46.619 --> 00:23:48.779 significantly lower rates of complications like 00:23:48.779 --> 00:23:51.000 orchitis and meningitis. So the vaccine acts 00:23:51.000 --> 00:23:53.039 like a seatbelt. You might still get in a crash, 00:23:53.140 --> 00:23:55.019 you might get a dent, but you don't fly through 00:23:55.019 --> 00:23:57.200 the windshield. That is the perfect analogy. 00:23:57.480 --> 00:24:00.079 It converts a potential catastrophe into a manageable 00:24:00.079 --> 00:24:03.039 nuisance. This brings us to the final provocative 00:24:03.039 --> 00:24:05.000 thought for our outro. You mentioned it in your 00:24:05.000 --> 00:24:07.500 notes. The third dose. This is where the science 00:24:07.500 --> 00:24:10.079 is evolving in real time. Because of these college 00:24:10.079 --> 00:24:13.259 outbreaks, the CDC now recommends a third dose 00:24:13.259 --> 00:24:16.119 of the MMR vaccine for people who are identified 00:24:16.119 --> 00:24:18.359 as being part of an outbreak group. So if my 00:24:18.359 --> 00:24:20.259 dorm has a mumps case, I should go get a booster 00:24:20.259 --> 00:24:22.759 shot. Exactly. It's a public health strategy 00:24:22.759 --> 00:24:25.660 to quickly boost those antibody levels back up 00:24:25.660 --> 00:24:28.480 to fight off the high level of viral exposure 00:24:28.480 --> 00:24:31.339 in that close contact setting. It acknowledges 00:24:31.339 --> 00:24:34.099 that immunology isn't one and done. It's dynamic. 00:24:34.279 --> 00:24:36.660 I like that. It shows that medicine is always 00:24:36.660 --> 00:24:39.220 learning, always adapting. Always. You have to 00:24:39.220 --> 00:24:41.400 be. All right. Let's do a rapid fire recap. The 00:24:41.400 --> 00:24:43.920 elevator pitch for the month's 80 -20. Expert, 00:24:44.099 --> 00:24:47.180 take us home. OK. Five points. One, safety first, 00:24:47.359 --> 00:24:49.720 no aspirin, ever. Risk of race syndrome. Use 00:24:49.720 --> 00:24:52.619 Tylenol or Motrin. Got it. Isolation. Five days 00:24:52.619 --> 00:24:54.259 after the swelling starts. Not from the fever, 00:24:54.420 --> 00:24:56.660 from the swelling. Drop with precautions. OK. 00:24:57.220 --> 00:25:00.349 Three, assessment. Watch for his stiff neck. 00:25:00.630 --> 00:25:02.910 That's your meningitis red flag and in post puberty 00:25:02.910 --> 00:25:06.430 boys assess for testicular pain, which is orchitis. 00:25:06.730 --> 00:25:09.670 Neck and testes. Check it. Four. Counseling. 00:25:10.089 --> 00:25:13.789 On orchitis, remember, atrophy is common, but 00:25:13.789 --> 00:25:16.349 sterility is rare. You have to reassure the patient 00:25:16.349 --> 00:25:18.950 and the family with accurate information. Huge. 00:25:19.289 --> 00:25:24.029 And five. Vaccine. It's a live virus, so it's 00:25:24.029 --> 00:25:27.130 contraindicated in pregnancy and severe immunocompromise. 00:25:27.720 --> 00:25:30.079 And remember to recommend separate shots for 00:25:30.079 --> 00:25:32.380 babies to reduce the risk of febrile seizures. 00:25:32.660 --> 00:25:34.740 You nailed it. I feel like I could pass the NCLEX 00:25:34.740 --> 00:25:37.259 right now. Or maybe just the mumps section of 00:25:37.259 --> 00:25:39.180 it. One section at a time. That's how you do 00:25:39.180 --> 00:25:41.220 it. To our listeners, thank you for diving deep 00:25:41.220 --> 00:25:43.539 with us today. Whether you are scrubbing in for 00:25:43.539 --> 00:25:45.480 a shift or just trying to keep your family healthy, 00:25:45.839 --> 00:25:48.259 knowledge is the best PPE you have. Keep your 00:25:48.259 --> 00:25:50.460 patients safe. Check those ears. Check those 00:25:50.460 --> 00:25:52.579 vaccine records. And we will see you next time.
