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 --> 00:00:46.890 fast. Welcome to the emergency room. Welcome 00:00:46.890 --> 00:00:51.270 back to the Deep Dive. Today we are shifting 00:00:51.270 --> 00:00:54.250 gears just a little bit. Usually we take a broad, 00:00:54.369 --> 00:00:56.700 you know, a wide angle look. at a topic, sort 00:00:56.700 --> 00:00:58.979 of scanning the horizon. Yeah, the big picture. 00:00:59.179 --> 00:01:03.479 But today, today we are zooming in. We are putting 00:01:03.479 --> 00:01:06.560 on a very specific set of hats. That's right. 00:01:06.640 --> 00:01:09.420 We are we're donning the hats of the pediatric 00:01:09.420 --> 00:01:12.420 nursing educator and the exam coach. Exactly. 00:01:12.599 --> 00:01:14.379 Yeah. We've been looking at our listener feedback 00:01:14.379 --> 00:01:17.659 and we know that a huge portion of you are technically 00:01:18.140 --> 00:01:20.420 the learner. Right. You might be cramming for 00:01:20.420 --> 00:01:23.000 the NCLEX. You might be prepping for your CPN 00:01:23.000 --> 00:01:25.879 certification. Or honestly, you might just be 00:01:25.879 --> 00:01:27.900 about to step onto a pediatric floor for your 00:01:27.900 --> 00:01:29.799 first shift and you want to make sure your practice 00:01:29.799 --> 00:01:32.819 is safe. Exactly. And we know the struggle. You 00:01:32.819 --> 00:01:34.920 have textbooks that are literally a thousand 00:01:34.920 --> 00:01:37.099 pages long. Oh, I remember them well. You have 00:01:37.099 --> 00:01:39.359 PowerPoint slides from nursing school that are 00:01:39.359 --> 00:01:42.939 just lists of symptoms with absolutely no context. 00:01:43.000 --> 00:01:45.019 Just bullet points. Just bullet points. And you 00:01:45.019 --> 00:01:47.579 have that lingering anxiety of what is actually 00:01:47.469 --> 00:01:50.129 going to kill my patient or you know what is 00:01:50.129 --> 00:01:53.849 actually going to be on the exam and that is 00:01:53.849 --> 00:01:56.049 the noise we are here to cut through we're going 00:01:56.049 --> 00:01:58.310 to look for the signal the signal and the noise 00:01:58.310 --> 00:02:01.450 the safe practice signal and the topic we are 00:02:01.450 --> 00:02:04.769 diving into today is fascinating because it's 00:02:04.640 --> 00:02:07.260 is, well, it's a massive paradox. It really is. 00:02:07.280 --> 00:02:09.460 We're talking about rubella. Also known as German 00:02:09.460 --> 00:02:12.060 measles. And the paradox, and this is our initial 00:02:12.060 --> 00:02:14.560 hook here, is that if you are a five -year -old 00:02:14.560 --> 00:02:17.500 kid and you get rubella, it's usually a nothing 00:02:17.500 --> 00:02:20.500 burger. Right. It's mild. It's a rash. You're 00:02:20.500 --> 00:02:22.960 fine in three days. It's an inconvenience at 00:02:22.960 --> 00:02:25.580 most. Precisely. But, and this is the critical 00:02:25.580 --> 00:02:29.159 but, if you are developing fetus, rubella is 00:02:29.159 --> 00:02:31.699 catastrophic. Wow. It is arguably one of the 00:02:31.699 --> 00:02:34.580 most destructive viruses for the unborn. And 00:02:34.580 --> 00:02:36.639 that is why we talk about it. We don't study 00:02:36.639 --> 00:02:39.259 rubella for the sake of the kindergartner. No. 00:02:39.280 --> 00:02:41.120 We study it for the sake of the pregnant woman 00:02:41.120 --> 00:02:43.319 standing next to the kindergartner. So our mission 00:02:43.319 --> 00:02:46.360 today is to cross reference a stack of sources. 00:02:46.460 --> 00:02:49.280 I've got the CDC pink book, clinical profiles, 00:02:49.639 --> 00:02:52.280 lecture notes, and we're going to build the ultimate 00:02:52.280 --> 00:02:55.680 80 -20 study guide. The Pareto principle in action. 00:02:55.879 --> 00:02:58.759 Exactly, the 20 % of information that gives you 00:02:58.759 --> 00:03:01.319 80 % of the results on exams and in clinical 00:03:01.319 --> 00:03:04.120 practice. We have a roadmap for this. Part one 00:03:04.120 --> 00:03:06.740 is the master 80 -20 map. We need to understand 00:03:06.740 --> 00:03:08.879 the pattern exam writers love before we get into 00:03:08.879 --> 00:03:12.060 the weeds. Part two is the deep dive lecture 00:03:12.060 --> 00:03:15.159 system by system breakdown of rubella. And then? 00:03:15.319 --> 00:03:17.340 And part three is the cross -linking and differential 00:03:17.340 --> 00:03:20.539 diagnosis. How do you tell this apart from regular 00:03:20.539 --> 00:03:23.819 measles or scarlet fever? Because they can look 00:03:23.819 --> 00:03:26.479 similar. I love it. Let's jump right into part 00:03:26.479 --> 00:03:29.479 A, the master 80 -20 map. You always say that 00:03:29.479 --> 00:03:32.039 pediatric infections fall into patterns. What 00:03:32.039 --> 00:03:34.840 is the high -yield pattern for rubella? So before 00:03:34.840 --> 00:03:37.419 we even memorize a single symptom, you need to 00:03:37.419 --> 00:03:40.680 recognize the teratogenic pattern. Teratogenic, 00:03:41.240 --> 00:03:43.990 meaning harmful to a fetus. Exactly. This is 00:03:43.990 --> 00:03:46.310 the highest yield concept. In the world of pediatric 00:03:46.310 --> 00:03:48.610 exams and safety, rubella is almost always a 00:03:48.610 --> 00:03:50.629 question about pregnancy safety. OK, let's unpack 00:03:50.629 --> 00:03:52.629 this. Because usually when we talk about a sick 00:03:52.629 --> 00:03:54.750 kid, the focus is on the kid. But you're saying 00:03:54.750 --> 00:03:59.150 here the focus shifts. It has to, 100%. The most 00:03:59.150 --> 00:04:01.270 dangerous thing about a rubella patient isn't 00:04:01.270 --> 00:04:03.370 the patient standing in front of you. OK. It 00:04:03.370 --> 00:04:06.810 is the pregnant person in the room or even the 00:04:06.810 --> 00:04:09.379 one who might walk into the room. Wow. This leads 00:04:09.379 --> 00:04:12.199 to a critical decision point that exam writers 00:04:12.199 --> 00:04:15.620 absolutely love. It's all about assignment logic. 00:04:15.879 --> 00:04:17.939 Assignment logic. You mean, who takes care of 00:04:17.939 --> 00:04:21.540 whom? Exactly. Picture this question. You're 00:04:21.540 --> 00:04:24.240 the charge nurse. You have a patient in the ER 00:04:24.240 --> 00:04:27.379 with a fever and a rash, suspected rubella. OK. 00:04:27.660 --> 00:04:29.839 You have a staff of nurses. Yeah. One of those 00:04:29.839 --> 00:04:31.819 nurses is pregnant, or maybe she's mentioned 00:04:31.819 --> 00:04:34.660 she's trying to conceive. Can that nurse be assigned 00:04:34.660 --> 00:04:36.740 to the rubella patient? And the answer is a hard 00:04:36.740 --> 00:04:39.579 no. A definite no. It is a hard, non -negotiable 00:04:39.579 --> 00:04:41.779 no. You just don't take that risk. If a nurse 00:04:41.779 --> 00:04:43.980 is pregnant, she should never ever be assigned 00:04:43.980 --> 00:04:46.600 to a rubella patient, confirmed or even suspected. 00:04:46.899 --> 00:04:50.000 And why is the risk so high? The risk of congenital 00:04:50.000 --> 00:04:53.019 rubella syndrome, or CRS, if she's unvaccinated 00:04:53.019 --> 00:04:55.660 or maybe her immunity has waned over time, is 00:04:55.660 --> 00:04:58.060 just too high. Especially in the first trimester. 00:04:58.319 --> 00:05:00.720 The sources were very specific about that timing, 00:05:00.879 --> 00:05:04.230 right? The first 12 weeks? Yes. The pink book 00:05:04.230 --> 00:05:06.649 source, which is sort of the Bible for vaccines, 00:05:07.310 --> 00:05:10.449 specifically notes that the risk of CRS is highest 00:05:10.449 --> 00:05:14.589 and the defects are most severe if that infection 00:05:14.589 --> 00:05:17.089 occurs in the first 12 weeks of gestation. And 00:05:17.089 --> 00:05:19.709 that's because what's happening then? We're talking 00:05:19.709 --> 00:05:21.910 about the time when organogenesis is happening. 00:05:21.970 --> 00:05:24.370 The organs are being built. Literally. The heart 00:05:24.370 --> 00:05:27.649 is forming, the eyes, the ears, the brain. The 00:05:27.649 --> 00:05:30.319 virus gets in there and just... Well, it stops 00:05:30.319 --> 00:05:32.339 the process. It's like pulling the permit on 00:05:32.339 --> 00:05:34.480 a construction site while the foundation is being 00:05:34.480 --> 00:05:37.040 poured. That's a perfect analogy. If you stop 00:05:37.040 --> 00:05:39.860 the building process at week eight, you get a 00:05:39.860 --> 00:05:42.819 very different and much more devastating result 00:05:42.819 --> 00:05:45.000 than if you stop it at week 30. So that's the 00:05:45.000 --> 00:05:47.199 teratogenic pattern. That's number one. What's 00:05:47.199 --> 00:05:49.600 the next pattern on our map? The isolation pattern. 00:05:49.600 --> 00:05:51.939 This falls under infection control. And this 00:05:51.939 --> 00:05:53.720 is where people get tripped up on timelines. 00:05:53.860 --> 00:05:56.920 The priority action is droplet precautions. But 00:05:56.920 --> 00:05:59.579 here's the trap, the seven and seven rule. Seven 00:05:59.579 --> 00:06:01.920 and seven. Break that down for us. The sources 00:06:01.920 --> 00:06:04.379 are pretty consistent on this. A patient is contagious 00:06:04.379 --> 00:06:06.660 for about seven days before the rash appears. 00:06:06.939 --> 00:06:09.600 Before. And then for another seven days after 00:06:09.600 --> 00:06:12.600 the rash appears. Wait, wait. Seven days before. 00:06:12.680 --> 00:06:14.600 So they're walking around school, the grocery 00:06:14.600 --> 00:06:16.779 store, spreading the virus, and they don't even 00:06:16.779 --> 00:06:19.620 have a spot on them yet. Exactly. And that is 00:06:19.620 --> 00:06:22.000 the timeline trap. By the time you see the rash 00:06:22.000 --> 00:06:24.680 and think, oh, I should isolate this kid, they 00:06:24.680 --> 00:06:26.699 have already been spreading it for a full week. 00:06:26.939 --> 00:06:30.779 Wow. This is a classic exam setup. The question 00:06:30.779 --> 00:06:32.839 will describe an exposure that happened five 00:06:32.839 --> 00:06:36.180 days ago before the rash appeared and ask if 00:06:36.180 --> 00:06:39.199 the contact is at risk. And the answer is absolutely 00:06:39.199 --> 00:06:42.000 yes. Absolutely yes. That is terrifying from 00:06:42.000 --> 00:06:44.439 a public health perspective, but excellent to 00:06:44.439 --> 00:06:46.199 know for an exam. It sort of feels like closing 00:06:46.199 --> 00:06:48.860 the barn door after the horse is bolted. In terms 00:06:48.860 --> 00:06:51.980 of community spread, yes, it's tough. Yeah. But 00:06:51.980 --> 00:06:54.779 in the hospital, isolation is about preventing 00:06:54.779 --> 00:06:58.220 further spread. If that child is admitted, they 00:06:58.220 --> 00:07:00.240 are still a hazard to the other patients on the 00:07:00.240 --> 00:07:02.560 floor for another week. Let's clarify droplet 00:07:02.560 --> 00:07:04.319 precautions because I feel like students often 00:07:04.319 --> 00:07:06.879 confuse this with airborne. They do all the time. 00:07:07.699 --> 00:07:10.220 Robilla travels in large droplets from sneezes 00:07:10.220 --> 00:07:13.060 and coughs. Physics dictates these droplets are 00:07:13.060 --> 00:07:15.600 heavy. They fall to the ground within about three, 00:07:15.639 --> 00:07:18.319 maybe six feet. They don't hang in the air for 00:07:18.319 --> 00:07:21.300 hours like measles or tuberculosis, which are 00:07:21.300 --> 00:07:23.500 airborne. So for a droplet, you need a surgical 00:07:23.500 --> 00:07:26.879 mask, not an N95 respirator. Correct. But here 00:07:26.879 --> 00:07:30.519 is a clinical critical piece regarding cohorting. 00:07:30.720 --> 00:07:33.560 Putting patients in the same room. Right. If 00:07:33.560 --> 00:07:35.259 you're short on private rooms, which happens 00:07:35.259 --> 00:07:38.279 all the time in PEDS, can you put a rubella patient 00:07:38.279 --> 00:07:41.740 with someone else? I would think no. Only if 00:07:41.740 --> 00:07:44.019 the other patient has confirmed rubella. You 00:07:44.019 --> 00:07:47.000 absolutely cannot cohort a rubella suspect with 00:07:47.000 --> 00:07:49.220 an immunocompromised child or a child with a 00:07:49.220 --> 00:07:51.540 different virus. If you put a rubella kid in 00:07:51.540 --> 00:07:54.120 with an RSV kid, you have just created a disaster. 00:07:54.220 --> 00:07:56.000 You've cross -contaminated and made everything 00:07:56.000 --> 00:07:58.399 worse. Penentially worse. Okay, so we have our 00:07:58.399 --> 00:08:00.100 patterns, we know to watch out for pregnancy, 00:08:00.120 --> 00:08:02.180 and we know the tricky seven -in -seven rule. 00:08:02.660 --> 00:08:05.920 Now let's move to part B, the system -by -system 00:08:05.920 --> 00:08:09.339 lecture. Let's really get into rubella itself. 00:08:09.470 --> 00:08:11.550 Let's do it. We always like to start with a one 00:08:11.550 --> 00:08:14.069 -liner identifier. If rubella had a tagline, 00:08:14.089 --> 00:08:15.990 what would it be? It would be the three -day 00:08:15.990 --> 00:08:19.250 measles, or maybe the silent sniper. Ooh, I like 00:08:19.250 --> 00:08:21.970 silent sniper. Why that? Because clinically, 00:08:22.410 --> 00:08:26.029 for the child, it's a generally mild, self -limiting 00:08:26.029 --> 00:08:29.250 viral rash. It comes and goes quickly, hence 00:08:29.250 --> 00:08:31.569 three -day measles. Right. It's distinct from 00:08:31.569 --> 00:08:34.169 rubella, which is regular measles and much, much 00:08:34.169 --> 00:08:37.240 nastier. But it's a sniper. because while it 00:08:37.240 --> 00:08:39.919 looks mild on the surface, it's targeting the 00:08:39.919 --> 00:08:43.639 unborn with deadly accuracy. Let's get into the 00:08:43.639 --> 00:08:46.639 path though. Plain language, but accurate. What 00:08:46.639 --> 00:08:49.639 is actually happening inside the body? So the 00:08:49.639 --> 00:08:52.000 agent is the rubivirus. It's part of the toga 00:08:52.000 --> 00:08:54.539 viridae family and more recently classified under 00:08:54.539 --> 00:08:56.940 metanoviridae. But for your purposes, just know 00:08:56.940 --> 00:08:59.700 it's an RNA virus. And how does it get in? Respiratory 00:08:59.700 --> 00:09:01.860 route. You breathe it in, it enters through the 00:09:01.860 --> 00:09:04.019 nasopharynx, so the nose and throat. It sets 00:09:04.019 --> 00:09:06.500 up shop and starts replicating in the lymph nodes 00:09:06.500 --> 00:09:08.940 of the neck. That's its first stop. From there, 00:09:09.159 --> 00:09:11.379 it causes viremia. Which is just a fancy way 00:09:11.379 --> 00:09:12.960 of saying the virus spills into the bloodstream. 00:09:13.120 --> 00:09:15.159 Exactly. Virus in the blood. And once it's in 00:09:15.159 --> 00:09:17.419 the blood, it can go everywhere. The viremia 00:09:17.419 --> 00:09:20.370 spreads to the skin. which causes the rash we 00:09:20.370 --> 00:09:23.289 see. But critically, it spreads to the placenta. 00:09:23.389 --> 00:09:25.149 And this is where the real damage happens. This 00:09:25.149 --> 00:09:27.230 is where the damage is fascinating and horrifying. 00:09:27.950 --> 00:09:30.830 In a fetus, the virus acts by destroying cells 00:09:30.830 --> 00:09:34.509 and, crucially, by stopping cell division. Stopping 00:09:34.509 --> 00:09:37.070 cell division? You mean mitosis? Yes, mitosis 00:09:37.070 --> 00:09:40.110 arrest. It literally tells the cells to stop 00:09:40.110 --> 00:09:43.330 dividing. Imagine a developing heart or an eye 00:09:43.330 --> 00:09:45.730 that needs to grow a certain number of cells 00:09:45.730 --> 00:09:48.149 to form correctly. Right. It has a blueprint. 00:09:48.490 --> 00:09:50.470 It has a blueprint. Rubella comes in and says, 00:09:50.809 --> 00:09:54.350 stop. The cells don't divide. The organ doesn't 00:09:54.350 --> 00:09:57.029 grow. That leads to growth retardation and all 00:09:57.029 --> 00:09:59.820 kinds of structural defects. It's not just attacking 00:09:59.820 --> 00:10:02.360 tissue, it's preventing the tissue from ever 00:10:02.360 --> 00:10:04.259 being built in the first place. That explains 00:10:04.259 --> 00:10:06.639 why the timing matters so much. If you stop the 00:10:06.639 --> 00:10:08.980 building process at week 8, you get a very different 00:10:08.980 --> 00:10:11.519 result than if you stop it at week 30. Precisely. 00:10:11.700 --> 00:10:13.659 The earlier the infection, the more fundamental 00:10:13.659 --> 00:10:15.460 the damage. Okay, let's talk about presentation. 00:10:15.980 --> 00:10:18.080 How does this look when a patient walks in? Does 00:10:18.080 --> 00:10:20.220 it look different in a baby versus an adult? 00:10:20.659 --> 00:10:23.179 Huge difference. And this is a need -to -know 00:10:23.179 --> 00:10:26.399 distinction for exams. In infants and young children, 00:10:26.820 --> 00:10:29.759 they are Often asymptomatic or the symptoms are 00:10:29.759 --> 00:10:31.940 so so mild so you might not even know they're 00:10:31.940 --> 00:10:34.940 sick You might not usually the rash at the first 00:10:34.940 --> 00:10:38.940 sign so no warning just boom rash often. Yes 00:10:38.940 --> 00:10:41.500 Mom notices spots when she's giving a bath, and 00:10:41.500 --> 00:10:44.240 that's it but in older children adolescents and 00:10:44.240 --> 00:10:47.940 adults we see a prodrome. A prodrome. That's 00:10:47.940 --> 00:10:50.379 that period of feeling gross before the main 00:10:50.379 --> 00:10:52.360 event. Right. For about one to five days before 00:10:52.360 --> 00:10:54.799 the rash, they feel crummy, low -grade fever, 00:10:55.080 --> 00:10:58.200 malaise, headache, maybe some mild conjunctivitis, 00:10:58.299 --> 00:11:00.799 pink eye, and choriza, which is a runny nose. 00:11:01.240 --> 00:11:03.460 Just feels like a mild cold. There was a specific 00:11:03.460 --> 00:11:05.539 finding for adult females in the source material 00:11:05.539 --> 00:11:07.500 that caught my eye. It seemed really high, like 00:11:07.500 --> 00:11:10.200 70%. Yes. This is a major nice to know context 00:11:10.200 --> 00:11:12.259 that becomes need to know if you're treating 00:11:12.259 --> 00:11:15.860 adults. Up to 70 % of adult women who get rubella 00:11:15.860 --> 00:11:18.460 experience arthralgia or arthritis. So joint 00:11:18.460 --> 00:11:21.419 pain. Significant joint pain. Fingers, wrists, 00:11:21.620 --> 00:11:23.779 knees. It can be quite debilitating. It can last 00:11:23.779 --> 00:11:26.259 for a month or more. It's rare in children and 00:11:26.259 --> 00:11:29.059 rare in men. But for women, it's a hallmark. 00:11:29.309 --> 00:11:31.669 If you have an adult woman with a rash and her 00:11:31.669 --> 00:11:33.990 wrists are killing her, you have to think rubella. 00:11:34.289 --> 00:11:37.750 That is fascinating. Okay, let's get into the 00:11:37.750 --> 00:11:40.470 core of the exam content. The need -to -know 00:11:40.470 --> 00:11:43.350 assessment findings. We are standing at the bedside. 00:11:43.830 --> 00:11:46.169 What are we looking for? First, let's characterize 00:11:46.169 --> 00:11:49.870 a rash. It's macula papular. Which means? Flat 00:11:49.870 --> 00:11:52.809 red spots macules and raised bums papules. A 00:11:52.809 --> 00:11:55.730 mix of both. But the direction is key. It is 00:11:55.730 --> 00:11:58.529 cephalocautal. Fancy word for head to toe. Correct. 00:11:58.590 --> 00:12:00.529 It starts on the face and spreads down to the 00:12:00.529 --> 00:12:03.210 toes, and it moves fast. By the time it reaches 00:12:03.210 --> 00:12:05.610 the legs, it might already be fading from the 00:12:05.610 --> 00:12:07.529 face. And how long does it stick around? It's 00:12:07.529 --> 00:12:10.110 usually gone in about three days. Hence, three 00:12:10.110 --> 00:12:12.289 -day measles. And how does it look compared to 00:12:12.289 --> 00:12:14.950 regular measles? It's fainter. Regular measles 00:12:14.950 --> 00:12:18.470 rubiola looks angry, deep red, and the spots 00:12:18.470 --> 00:12:21.370 coalesce. They merge together into big blotches. 00:12:21.929 --> 00:12:24.389 Ugh. Rubella stays more distinct, more pink, 00:12:24.950 --> 00:12:28.440 less angry. And here's a weird clinical pearl 00:12:28.440 --> 00:12:30.820 from the sources. The rash can be more prominent 00:12:30.820 --> 00:12:33.740 after a hot shower or bath. Interesting. So if 00:12:33.740 --> 00:12:35.960 they come in overheated, it might look worse 00:12:35.960 --> 00:12:38.639 than it is. Exactly. Or a parent might notice 00:12:38.639 --> 00:12:40.860 it for the first time after a bath time. What 00:12:40.860 --> 00:12:43.240 about the lymph nodes? You mentioned they replicate 00:12:43.240 --> 00:12:46.720 there. This is a classic textbook clue. You are 00:12:46.720 --> 00:12:49.620 looking for distinctive swelling in three specific 00:12:49.620 --> 00:12:51.860 areas. Okay, what are they? Post -dericular, 00:12:52.139 --> 00:12:54.820 which is behind the ears. posterior cervical, 00:12:55.059 --> 00:12:57.759 on the back of the neck, and subcipital, right 00:12:57.759 --> 00:12:59.919 at the base of the skull. Behind the ears is 00:12:59.919 --> 00:13:01.679 the big one, I remember. That's the one they 00:13:01.679 --> 00:13:04.480 love to test. If you feel swollen nodes behind 00:13:04.480 --> 00:13:07.000 the ears combined with a rash, like we've described, 00:13:07.679 --> 00:13:10.059 rubella should be very high on your list of possibilities. 00:13:10.320 --> 00:13:12.700 And what about inside the mouth? We always hear 00:13:12.700 --> 00:13:15.559 about coplic spots with measles. Does rubella 00:13:15.559 --> 00:13:18.559 have an equivalent? Sort of. They're called Forsheimer 00:13:18.559 --> 00:13:22.960 spots. Forsheimer? Yeah, F -O -R -S -C -H. H 00:13:22.960 --> 00:13:27.100 -E -I -M -E -R. These are small red spots, or 00:13:27.100 --> 00:13:29.860 patechiae, on the soft palate. The back of the 00:13:29.860 --> 00:13:32.460 roof of the mouth. Exactly. Now, the source notes 00:13:32.460 --> 00:13:34.480 that these aren't 100 % diagnostic. They can 00:13:34.480 --> 00:13:36.840 happen in other things. But exam writers love 00:13:36.840 --> 00:13:39.639 to throw them in as a clue. If you see red spots 00:13:39.639 --> 00:13:42.600 on soft palate in a question stem, don't rule 00:13:42.600 --> 00:13:44.419 out rubella. How does that look different from 00:13:44.419 --> 00:13:46.480 strep throat? Strep gives you patechiae on the 00:13:46.480 --> 00:13:49.100 palate, too. It's hard visually. They can look 00:13:49.100 --> 00:13:52.700 very similar. But context is king. Strip throat 00:13:52.700 --> 00:13:55.240 usually has a high fever, a very sore throat, 00:13:55.519 --> 00:13:58.899 and classically no cough or runny nose. Rubel 00:13:58.899 --> 00:14:01.299 comes with the coriaceae, the runny nose, the 00:14:01.299 --> 00:14:03.940 cough, and then the body rash. You have to look 00:14:03.940 --> 00:14:05.419 at the whole patient, not just their palate. 00:14:05.639 --> 00:14:08.340 OK, so we suspect it. We see the rash, the nodes. 00:14:08.440 --> 00:14:10.659 How do we prove it? What are the key diagnostics? 00:14:10.879 --> 00:14:12.899 Well, clinical diagnosis is unreliable because 00:14:12.899 --> 00:14:15.360 so many viral rashes look alike. You need labs 00:14:15.360 --> 00:14:17.879 to be sure. What are we ordering? PCR from the 00:14:17.879 --> 00:14:20.580 nose, throat, or urine is the gold standard for 00:14:20.580 --> 00:14:23.639 detecting the actual virus. But for immune status, 00:14:23.899 --> 00:14:27.399 we look at IgM antibodies. And IgM means minute. 00:14:27.620 --> 00:14:30.009 Like, the infection is happening right now. I 00:14:30.009 --> 00:14:33.529 use Iimmediate. IgM indicates a recent acute 00:14:33.529 --> 00:14:36.190 infection. The optimal timing to draw this is 00:14:36.190 --> 00:14:38.950 about five days after symptom onset. Why the 00:14:38.950 --> 00:14:42.009 delay? If you draw it too early, the body hasn't 00:14:42.009 --> 00:14:43.950 had time to mount that antibody response, so 00:14:43.950 --> 00:14:45.990 you might get a false negative. Okay, so we have 00:14:45.990 --> 00:14:48.370 a diagnosis. We've done our assessment. What 00:14:48.370 --> 00:14:50.549 are our priority nursing interventions? What 00:14:50.549 --> 00:14:52.929 do we do first? Immediate isolation. That's number 00:14:52.929 --> 00:14:55.159 one. Get them into a room, put them on droplet 00:14:55.159 --> 00:14:58.159 precautions. Which means a mask for anyone entering 00:14:58.159 --> 00:15:01.059 the room. A mask for you and a mask for the patient 00:15:01.059 --> 00:15:02.860 if they have to leave the room for any reason. 00:15:03.480 --> 00:15:06.580 A private room is strongly preferred. And treatment. 00:15:06.899 --> 00:15:10.000 Is there a magic pill? Sadly no, it's viral. 00:15:10.620 --> 00:15:12.360 So supportive care is the name of the game. What 00:15:12.360 --> 00:15:14.909 does that entail? Fluids for hydration. because 00:15:14.909 --> 00:15:18.409 fever can dehydrate them. Antipyretics like acetaminophen 00:15:18.409 --> 00:15:20.490 or ibuprofen for the fever and that joint pain 00:15:20.490 --> 00:15:23.529 we talked about. No specific antiviral cure exists. 00:15:23.730 --> 00:15:26.309 It resolves on its own. And school. When can 00:15:26.309 --> 00:15:28.350 they go back? This goes back to the seven and 00:15:28.350 --> 00:15:31.289 seven rule. But for exclusion, the official CDC 00:15:31.289 --> 00:15:33.190 guidance is to keep them home from school or 00:15:33.190 --> 00:15:35.889 child care for seven days after the rash onset. 00:15:36.009 --> 00:15:38.169 OK. Now we need to talk about the crash list, 00:15:38.210 --> 00:15:39.730 the complications. You mentioned it's usually 00:15:39.730 --> 00:15:42.340 mild, but things can go wrong. They can. While 00:15:42.340 --> 00:15:44.259 CRS is the big one for the fetus, the patient 00:15:44.259 --> 00:15:47.399 themselves can have issues. One is thrombocytopenia. 00:15:47.779 --> 00:15:50.340 Low platelets. Right. It happens in about 1 in 00:15:50.340 --> 00:15:53.700 3 ,000 cases. So as a nurse, you are watching 00:15:53.700 --> 00:15:57.039 for bruising, petechia on the skin, or bleeding 00:15:57.039 --> 00:15:59.460 from the gums or nose. The really scary one. 00:16:00.059 --> 00:16:03.100 Encephalitis. Brain inflammation. It's rare, 00:16:03.240 --> 00:16:06.159 about 1 in 6 ,000 cases, but it can be devastating 00:16:06.159 --> 00:16:08.259 or fatal. What are the signs of that? You're 00:16:08.259 --> 00:16:10.379 watching for any change in level of consciousness, 00:16:10.659 --> 00:16:13.460 confusion, seizures, or a severe, unrelenting 00:16:13.460 --> 00:16:15.600 headache with a stiff neck. That's a neurological 00:16:15.600 --> 00:16:17.720 emergency. But let's go back to the exam writer 00:16:17.720 --> 00:16:19.659 favorite. The biggest complication isn't for 00:16:19.659 --> 00:16:22.399 the child. It's for the fetus. Congenital Rubella 00:16:22.399 --> 00:16:25.419 Syndrome, CRS. We need to drill this down. What 00:16:25.419 --> 00:16:28.620 does a CRS baby look like? There is a classic 00:16:28.620 --> 00:16:32.419 triad of defects you must memorize. If you memorize 00:16:32.419 --> 00:16:35.740 nothing else about CRS, memorize this triad. 00:16:35.740 --> 00:16:38.799 Okay, I'm ready. One. Deafness. sensor neural 00:16:38.799 --> 00:16:40.879 hearing loss. This is the most common finding. 00:16:41.519 --> 00:16:44.600 Two, eye abnormalities, most commonly cataracts, 00:16:44.679 --> 00:16:47.279 which are cloudy lenses, but also glaucoma or 00:16:47.279 --> 00:16:51.080 retinopathy. And three, cardiac defects, specifically 00:16:51.080 --> 00:16:54.879 patent ductus arteriosus, PDA, or pulmonary artery 00:16:54.879 --> 00:16:58.100 stenosis. Deafness, eyes, heart, got it. That's 00:16:58.100 --> 00:17:00.980 the triad. But there's a distinctive skin finding 00:17:00.980 --> 00:17:03.299 too, which is also high yield. The blueberry 00:17:03.299 --> 00:17:05.660 muffin rash. That sounds cute, but I assume it's 00:17:05.660 --> 00:17:08.720 not. Not cute at all. It represents dermal erythropoiesis. 00:17:08.819 --> 00:17:11.059 Meaning? Basically, the baby is making red blood 00:17:11.059 --> 00:17:13.079 cells in the skin because the bone marrow isn't 00:17:13.079 --> 00:17:15.299 working right or is just overwhelmed by the infection. 00:17:15.599 --> 00:17:17.539 It looked like purple or blue nodules scattered 00:17:17.539 --> 00:17:19.859 over the skin. Like little bruises under the 00:17:19.859 --> 00:17:22.079 skin. Exactly. It's a sign of severe systemic 00:17:22.079 --> 00:17:24.259 infection. If we see a blueberry muffin baby, 00:17:24.339 --> 00:17:26.079 what are we thinking? We are immediately thinking 00:17:26.079 --> 00:17:30.009 a torch infection. Yes. TORCH, toxoplasmosis, 00:17:30.369 --> 00:17:33.569 other rubella, CMV, herpes. It triggers an immediate 00:17:33.569 --> 00:17:36.210 massive workup. OK, let's pivot to prevention. 00:17:36.309 --> 00:17:38.730 This is all preventable, right? 100%. We have 00:17:38.730 --> 00:17:43.210 the MMR vaccine measles, mumps, rubella, or the 00:17:43.210 --> 00:17:47.029 MMRV, which adds varicella, or chickenpox. It's 00:17:47.029 --> 00:17:50.089 a live attenuated vaccine. And live is the key 00:17:50.089 --> 00:17:52.250 word there. Huge key word. It's so important. 00:17:52.849 --> 00:17:55.710 Because it's live, it carries specific contraindications 00:17:55.710 --> 00:17:58.240 you have to know. Number one has to be pregnancy. 00:17:59.000 --> 00:18:01.359 Absolutely. You cannot give a live virus vaccine 00:18:01.359 --> 00:18:03.720 to a pregnant woman. The theoretical risk to 00:18:03.720 --> 00:18:05.720 the fetus is just too high. And the second big 00:18:05.720 --> 00:18:08.420 one. Severe immunocompromise. Someone with advanced 00:18:08.420 --> 00:18:12.140 HIV and very low CD4 counts or someone on high 00:18:12.140 --> 00:18:14.859 dose chemotherapy. Their body can't handle even 00:18:14.859 --> 00:18:16.960 a weakened virus. What about the timeline for 00:18:16.960 --> 00:18:19.339 pregnancy? If a woman gets the shot, how long 00:18:19.339 --> 00:18:21.640 does she need to wait to get pregnant? She must 00:18:21.640 --> 00:18:24.000 avoid pregnancy for four weeks after vaccination. 00:18:24.250 --> 00:18:27.089 The CDC recommendation used to be three months, 00:18:27.390 --> 00:18:29.170 but they've shortened it to four weeks based 00:18:29.170 --> 00:18:32.089 on data. This is a standard discharge instruction. 00:18:32.250 --> 00:18:34.349 I saw a trap in the notes about egg allergies. 00:18:34.950 --> 00:18:37.410 Yes, this is a classic myth that just won't die. 00:18:38.029 --> 00:18:39.990 People think because some vaccines are grown 00:18:39.990 --> 00:18:43.150 in egg cultures, you can't give MMR to kids with 00:18:43.150 --> 00:18:45.690 egg allergies. And the answer is? The source 00:18:45.690 --> 00:18:49.230 explicitly states that egg allergy is not a contraindication. 00:18:50.220 --> 00:18:53.140 Even a child with a history of anaphylaxis to 00:18:53.140 --> 00:18:57.759 eggs can and should receive the MMR vaccine, 00:18:58.359 --> 00:19:00.180 usually in a setting where they can be monitored. 00:19:00.480 --> 00:19:02.220 That is a point for the listeners to highlight. 00:19:02.319 --> 00:19:04.619 Don't fall for the egg trap. Another trap is 00:19:04.619 --> 00:19:07.319 confusing it with other allergies, neomycin or 00:19:07.319 --> 00:19:09.500 gelatin allergies. These are components of the 00:19:09.500 --> 00:19:11.829 vaccine. So if the question says the kid had 00:19:11.829 --> 00:19:14.710 an anaphylactic reaction to gelatin, then you 00:19:14.710 --> 00:19:17.130 hold the vaccine. But not for eggs. Not for eggs. 00:19:17.250 --> 00:19:19.650 I want to talk about side effects because parents 00:19:19.650 --> 00:19:22.250 call about this all the time. The mini measles 00:19:22.250 --> 00:19:25.069 reaction. Yes. This is a massive parent education 00:19:25.069 --> 00:19:27.190 point. It's so important to set expectations. 00:19:27.569 --> 00:19:29.769 You give the MMR shot, the parent goes home, 00:19:30.190 --> 00:19:32.410 then seven to 12 days later the phone rings. 00:19:32.529 --> 00:19:34.910 And they're panicked. Panicked. My child has 00:19:34.910 --> 00:19:36.710 a fever and a rash. You gave them the measles. 00:19:36.730 --> 00:19:38.230 And you have to talk them off the ledge. You 00:19:38.230 --> 00:19:41.519 do. But this is an expected physiological response. 00:19:42.059 --> 00:19:45.079 About 5 % to 15 % of kids will get a fever, sometimes 00:19:45.079 --> 00:19:48.200 as high as 103 degrees Eris. And about 5 % get 00:19:48.200 --> 00:19:50.519 a rash. It happens roughly a week and a half 00:19:50.519 --> 00:19:52.539 after the shot. Why that delay? It's not like 00:19:52.539 --> 00:19:54.420 with a Tylenol reaction that happens right away. 00:19:54.539 --> 00:19:56.940 Because it's a live virus. It has to replicate 00:19:56.940 --> 00:19:58.859 a little bit to stimulate the immune system. 00:19:59.279 --> 00:20:01.940 That replication process takes time. And this 00:20:01.940 --> 00:20:04.900 is critical. This is not... the contagious wild 00:20:04.900 --> 00:20:08.220 type disease. It is a vaccine reaction. It's 00:20:08.220 --> 00:20:10.859 non -transmissible in the standard sense. The 00:20:10.859 --> 00:20:13.460 child is not contagious. So the advice to the 00:20:13.460 --> 00:20:16.160 parent is? Don't panic. This is normal. Treat 00:20:16.160 --> 00:20:18.279 the fever with acetaminophen or ibuprofen. It 00:20:18.279 --> 00:20:20.880 will pass in a day or two. This is a good sign. 00:20:21.099 --> 00:20:23.059 It means the vaccine is working and their immune 00:20:23.059 --> 00:20:25.079 system is building protection. We have to address 00:20:25.079 --> 00:20:27.680 the autism link. We absolutely have to be definitive 00:20:27.680 --> 00:20:29.900 here. The Institute of Medicine, which is now 00:20:29.900 --> 00:20:32.039 the National Academy of Medicine, has reviewed 00:20:32.039 --> 00:20:34.900 the evidence extensively. They explicitly refute, 00:20:35.000 --> 00:20:37.299 and that is the word the source uses, refute 00:20:37.299 --> 00:20:40.240 any causal relationship between the MMR vaccine 00:20:40.240 --> 00:20:42.750 and autism. It's important to have that firm 00:20:42.750 --> 00:20:45.630 language. Refute. Not, we think it's unlikely, 00:20:45.829 --> 00:20:49.190 but the data says no. Correct. The original study 00:20:49.190 --> 00:20:52.329 was retracted for fraud. There is no link. But 00:20:52.329 --> 00:20:55.569 there is a real, albeit rare risk we need to 00:20:55.569 --> 00:20:58.690 be honest about, febrile seizures. Talk to me 00:20:58.690 --> 00:21:01.269 about that. The risk of a febrile seizure is 00:21:01.269 --> 00:21:04.549 about one in every 3 ,000 to 4 ,000 doses of 00:21:04.549 --> 00:21:07.039 MMR. Which is tied to that high fever it can 00:21:07.039 --> 00:21:09.220 cause. Exactly. It's slightly higher if you use 00:21:09.220 --> 00:21:11.819 the combined MMRV with the varicella component 00:21:11.819 --> 00:21:14.539 as the first dose in toddlers. So from 12 to 00:21:14.539 --> 00:21:17.019 15 months. Wait, really? I thought one poke was 00:21:17.019 --> 00:21:20.740 always better. Usually, yes, but the data shows 00:21:20.740 --> 00:21:23.440 that for that specific age group, 12 to 47 months, 00:21:23.980 --> 00:21:26.059 the risk of febrile seizure is about twice as 00:21:26.059 --> 00:21:29.440 high with MMRV compared to giving MMR and varicella 00:21:29.440 --> 00:21:31.700 as two separate shots on the same day. That's 00:21:31.700 --> 00:21:34.400 fascinating. It is. For the second dose of four 00:21:34.400 --> 00:21:36.960 to six years, MMRV is preferred because that 00:21:36.960 --> 00:21:38.920 increased risk disappears. It's a very specific 00:21:38.920 --> 00:21:41.099 age -related phenomena. That is a deep dive nugget 00:21:41.099 --> 00:21:44.190 right there. Absolutely. Got it. Now, I want 00:21:44.190 --> 00:21:46.029 to move to a section that is specific to our 00:21:46.029 --> 00:21:48.190 master class approach. We need to connect this 00:21:48.190 --> 00:21:52.250 disease to development and milestones. How does 00:21:52.250 --> 00:21:56.109 rubella, specifically CRS, impact a child's development? 00:21:56.509 --> 00:21:59.089 This is critical. If we are looking at acquired 00:21:59.089 --> 00:22:02.329 rubella in a healthy school -aged kid, the impact 00:22:02.329 --> 00:22:04.829 is minimal. Right. Short -term disruption of 00:22:04.829 --> 00:22:06.990 school. Maybe they miss a soccer game. There 00:22:06.990 --> 00:22:08.930 are no long -term developmental issues usually. 00:22:09.289 --> 00:22:12.440 But for the CRS baby, The developmental threat 00:22:12.440 --> 00:22:15.079 is global. It affects everything. Let's break 00:22:15.079 --> 00:22:18.000 that down. Think about the triad again. Deafness. 00:22:18.460 --> 00:22:20.779 Hearing is the absolute foundation of speech 00:22:20.779 --> 00:22:23.779 and language acquisition. If a baby is born deaf 00:22:23.779 --> 00:22:26.619 from CRS, they will have profound speech delays 00:22:26.619 --> 00:22:28.799 unless we intervene very, very early with things 00:22:28.799 --> 00:22:31.579 like hearing aids or cochlear implants and sign 00:22:31.579 --> 00:22:34.279 language. And the eyes. The cataracts. Visual 00:22:34.279 --> 00:22:36.400 impairment impacts motor development. Babies 00:22:36.400 --> 00:22:38.319 learn to reach and crawl by seeing things they 00:22:38.319 --> 00:22:40.589 want. If they have cataracts, that motor drive 00:22:40.589 --> 00:22:44.130 is blunted. Plus, visual tracking is a huge cognitive 00:22:44.130 --> 00:22:46.789 milestone. So the nursing action here isn't just 00:22:46.789 --> 00:22:49.490 treat the virus. No. The virus has already done 00:22:49.490 --> 00:22:52.950 its damage in utero. The nursing action is early 00:22:52.950 --> 00:22:56.230 intervention referral. Immediately. These babies 00:22:56.230 --> 00:23:00.319 need audiology, ophthalmology, cardiology. physical 00:23:00.319 --> 00:23:03.500 therapy, occupational therapy, and speech therapy 00:23:03.500 --> 00:23:06.359 from day one. We are playing catch up from the 00:23:06.359 --> 00:23:08.039 moment they were born. There was also a chilling 00:23:08.039 --> 00:23:11.099 rule about the contagious baby. Yes. This is 00:23:11.099 --> 00:23:14.099 a massive safety and developmental issue. Babies 00:23:14.099 --> 00:23:17.059 born with CRS shed the virus in their urine and 00:23:17.059 --> 00:23:20.299 secretions for a very long time. How long? Up 00:23:20.299 --> 00:23:23.019 to one year. Sometimes longer. One year. So this 00:23:23.019 --> 00:23:26.160 baby is basically a walking or crawling biohazard 00:23:26.160 --> 00:23:28.640 to susceptible people. Exactly. The virus has 00:23:28.640 --> 00:23:30.400 integrated into their system and they're constantly 00:23:30.400 --> 00:23:32.359 shedding it. Think about the developmental and 00:23:32.359 --> 00:23:34.539 social impact of that. It's huge. We have to 00:23:34.539 --> 00:23:36.880 isolate this baby from susceptible populations. 00:23:37.319 --> 00:23:39.680 Grandparents. If they aren't immune, that's a 00:23:39.680 --> 00:23:42.920 risk. But especially pregnant aunts, family friends, 00:23:43.519 --> 00:23:46.309 daycare providers. So no standard daycare. This 00:23:46.309 --> 00:23:48.950 baby cannot be in a standard daycare setting 00:23:48.950 --> 00:23:51.210 if there are unimmunized children or pregnant 00:23:51.210 --> 00:23:54.109 staff. It creates this bubble of isolation around 00:23:54.109 --> 00:23:56.789 the family that can severely impact bonding and 00:23:56.789 --> 00:23:59.250 social support at a time when they need it most. 00:23:59.750 --> 00:24:01.529 Is there an off -ramp before the one -year mark? 00:24:01.789 --> 00:24:04.890 Can they be cleared? Yes. The protocol is that 00:24:04.890 --> 00:24:07.069 infants should be screened monthly after they 00:24:07.069 --> 00:24:10.109 turn three months old. If you get two consecutive 00:24:10.109 --> 00:24:12.829 negative tests on nasopharyngeal swabs or urine 00:24:12.829 --> 00:24:15.490 collected at least one month apart, then you 00:24:15.490 --> 00:24:17.450 can consider them non -contagious. But until 00:24:17.450 --> 00:24:19.869 then, strict contact and droplet precautions. 00:24:20.009 --> 00:24:23.160 Yes. And that is heavy. It really reinforces 00:24:23.160 --> 00:24:25.559 why vaccination is a community responsibility, 00:24:26.000 --> 00:24:28.920 not just an individual choice. Absolutely. Okay, 00:24:28.960 --> 00:24:31.539 let's move to Part C, cross -linking and consensus. 00:24:31.680 --> 00:24:33.339 We need to make sure we don't confuse rubella 00:24:33.339 --> 00:24:35.180 with its lookalikes. Let's do a quick comparison. 00:24:35.559 --> 00:24:38.279 Rubella versus rubella, German measles versus 00:24:38.279 --> 00:24:40.460 regular measles. Okay, visualize a table in your 00:24:40.460 --> 00:24:43.299 mind. Column A, rubella. Column B, rubella. Let's 00:24:43.299 --> 00:24:46.640 do it. For rubella. The rash lasts three days. 00:24:46.920 --> 00:24:50.079 The fever is low grade. The keynote finding is 00:24:50.079 --> 00:24:52.440 post -curricular, behind the ears. And the kid 00:24:52.440 --> 00:24:55.799 generally feels, you know, okay, mildly ill. 00:24:56.000 --> 00:24:59.180 And for rubeola. Rubeola. Yeah. The rash lasts 00:24:59.180 --> 00:25:01.200 five to six days or longer. The fever is H -I 00:25:01.200 --> 00:25:04.819 -G -H, 103, 104 degrees Fahrenheit. The key mouth 00:25:04.819 --> 00:25:07.660 finding is couplic spots. Those little white 00:25:07.660 --> 00:25:10.079 spots inside the cheek. The three C's? The three 00:25:10.079 --> 00:25:13.039 C's. Cough, cariesa, and severe conjunctivitis. 00:25:13.480 --> 00:25:15.519 With rubeola, the patient looks devastatingly 00:25:15.519 --> 00:25:17.920 sick. They're miserable. So rubeola is the big 00:25:17.920 --> 00:25:20.319 bad wolf, and rubella is the sneakier, quieter 00:25:20.319 --> 00:25:22.160 cousin. That's a great way to put it. Rubeola 00:25:22.160 --> 00:25:24.079 knocks you down hard. Rubella might just tap 00:25:24.079 --> 00:25:25.720 you on the shoulder, but it carries a knife for 00:25:25.720 --> 00:25:27.900 the fetus. What about scarlet fever? That's another 00:25:27.900 --> 00:25:30.579 red rash. Right. But the scarlet fever is bacterial. 00:25:30.680 --> 00:25:32.819 It's from group A strep. The key differentiator 00:25:32.819 --> 00:25:35.319 is the texture of the rash. Texture. Scarlet 00:25:35.319 --> 00:25:37.579 fever feels like sandpaper. If you run your hand 00:25:37.579 --> 00:25:40.480 over the child's chest, it feels rust. Rubella 00:25:40.480 --> 00:25:44.000 is smooth maculopapular. Also, scarlet fever 00:25:44.000 --> 00:25:46.559 has the strawberry tongue and often a very red 00:25:46.559 --> 00:25:49.740 sore throat. Rubella does not. Sandpaper versus 00:25:49.740 --> 00:25:52.039 smooth, that's a great exam differentiator. One 00:25:52.039 --> 00:25:54.480 note on consensus from our sources. We notice 00:25:54.480 --> 00:25:56.779 a slight discrepancy in the incubation period. 00:25:57.079 --> 00:26:01.039 Some sources say 1223 days, others say 1421. 00:26:01.200 --> 00:26:03.660 What's the safe answer for an exam? The safe 00:26:03.660 --> 00:26:07.319 exam answer and the average is 14 days. If you 00:26:07.319 --> 00:26:09.059 stick with two weeks, you're usually in the clear. 00:26:09.299 --> 00:26:11.240 And the arthritis rates? Also very slightly. 00:26:11.500 --> 00:26:14.059 Some said 25 percent, others up to 70 percent 00:26:14.059 --> 00:26:16.559 in women. The qualitative fact is what matters. 00:26:16.779 --> 00:26:19.019 It is common in adult women and rare in children. 00:26:19.440 --> 00:26:21.380 Don't get hung up on the specific percentage, 00:26:21.720 --> 00:26:24.319 just know the demographic. What about rosiola? 00:26:24.910 --> 00:26:28.450 another rash disease. Ah, yes. Exansum subitum. 00:26:28.769 --> 00:26:31.210 Rosiola is the high fever then rash disease. 00:26:31.349 --> 00:26:34.430 Okay, explain that. Rosiola starts with a terrifyingly 00:26:34.430 --> 00:26:37.509 high fever, like 103, 104, for three to five 00:26:37.509 --> 00:26:40.210 days. But the kid often acts surprisingly normal, 00:26:40.269 --> 00:26:42.170 they're not that sick. Then the fever breaks, 00:26:42.289 --> 00:26:44.390 it just vanishes, and boom, the rash appears. 00:26:44.690 --> 00:26:47.490 So the rash comes after the fever is gone. Exactly. 00:26:47.890 --> 00:26:50.329 Rubell is the opposite. The fever and rash happen 00:26:50.329 --> 00:26:53.180 together. or the ash comes after a mild prodrome. 00:26:53.559 --> 00:26:56.140 If the fever goes away and then the rash starts, 00:26:56.740 --> 00:26:58.700 you should be thinking roseola, not rubella. 00:26:58.940 --> 00:27:02.700 Fever breaks, rash takes. That's roseola. That's 00:27:02.700 --> 00:27:04.480 a great mnemonic. We are coming up on the end 00:27:04.480 --> 00:27:06.359 of our deem dive. Let's bring it all home with 00:27:06.359 --> 00:27:09.079 a summary. What are the key takeaways our listeners 00:27:09.079 --> 00:27:11.019 need to walk away with? Okay, let's distill it. 00:27:11.240 --> 00:27:14.359 Number one, rubella equals German measles equals 00:27:14.359 --> 00:27:16.819 three -day measles. It's generally mild for the 00:27:16.819 --> 00:27:18.799 kid, but incredibly dangerous for the fetus. 00:27:18.900 --> 00:27:21.440 Number two. The rash starts on the face and moves 00:27:21.440 --> 00:27:24.480 down, cephalocautal, and you'll see those swollen 00:27:24.480 --> 00:27:27.279 post -curricular lymph nodes. Three. The vaccine, 00:27:27.579 --> 00:27:30.740 MMR, is a live virus, which means no giving it 00:27:30.740 --> 00:27:33.559 to pregnant women or the severely immunocompromised. 00:27:34.160 --> 00:27:36.160 And women need to wait four weeks after the shot 00:27:36.160 --> 00:27:40.400 to conceive. Four. The CRS triad. Deafness, cataracts, 00:27:40.460 --> 00:27:42.960 and cardiac defects. Know it, love it, don't 00:27:42.960 --> 00:27:46.779 miss it. And five. Isolation. Droplet precautions. 00:27:47.620 --> 00:27:50.839 The patient is contagious from seven days before 00:27:50.839 --> 00:27:53.900 the rash to seven days after. And that blueberry 00:27:53.900 --> 00:27:56.859 muffin rash in a newborn is a sign of severe 00:27:56.859 --> 00:27:59.839 congenital infection. Perfect summary. And for 00:27:59.839 --> 00:28:01.660 that final provocative thought, you know, we 00:28:01.660 --> 00:28:04.549 read these statistics. And one of them just really 00:28:04.549 --> 00:28:06.390 stood out. It did. The one from the clinical 00:28:06.390 --> 00:28:09.509 profile source. It said that 25 to 50 percent 00:28:09.509 --> 00:28:12.009 of rubella cases are asymptomatic. Up to half 00:28:12.009 --> 00:28:14.609 of all cases have no symptoms. Up to half. So 00:28:14.609 --> 00:28:16.950 imagine a world where we stop vaccinating because 00:28:16.950 --> 00:28:19.250 it's a mild disease. We get that sometimes. It's 00:28:19.250 --> 00:28:21.940 just a little rash. In that world, you have people 00:28:21.940 --> 00:28:24.619 walking around in grocery stores, on buses, in 00:28:24.619 --> 00:28:26.660 doctor's waiting rooms, shedding this virus, 00:28:26.960 --> 00:28:28.960 completely unaware that they are infected. And 00:28:28.960 --> 00:28:30.599 standing right next to them is a woman in her 00:28:30.599 --> 00:28:32.839 first trimester of pregnancy, who maybe couldn't 00:28:32.839 --> 00:28:34.960 get the vaccine for some reason, or whose immunity 00:28:34.960 --> 00:28:37.220 has faded. And she has no idea she's being exposed? 00:28:37.500 --> 00:28:40.420 None. The vaccine isn't just for the child who 00:28:40.420 --> 00:28:43.200 gets the shot. It's a shield for the unborn. 00:28:43.720 --> 00:28:46.480 When you vaccinate a child against rubella, you 00:28:46.480 --> 00:28:49.440 are actively protecting a future baby from being 00:28:49.440 --> 00:28:52.390 born blind, or deaf, or with a heart that needs 00:28:52.390 --> 00:28:55.730 multiple surgeries to fix. That is the real weight 00:28:55.730 --> 00:28:57.789 of this topic. That puts it all into perspective. 00:28:57.849 --> 00:29:00.230 It's not just about the patient in the bed. It's 00:29:00.230 --> 00:29:02.809 about the entire community, present and future. 00:29:03.109 --> 00:29:05.589 Exactly. Thank you for unpacking this with us. 00:29:05.710 --> 00:29:08.150 To all our learners out there, whether you're 00:29:08.150 --> 00:29:10.109 cramming for finals or prepping for your shift, 00:29:10.309 --> 00:29:12.829 you've got this. You really do. Trust your training. 00:29:13.170 --> 00:29:15.809 Look for these patterns we talked about and always, 00:29:15.849 --> 00:29:18.049 always keep your patients safe. We'll see you 00:29:18.049 --> 00:29:20.509 on the next Deep Dive. Close the textbook, take 00:29:20.509 --> 00:29:22.670 a breath, good luck. You've got this.
