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 --> 00:00:47.170 fast. Welcome to the emergency room. Welcome 00:00:47.170 --> 00:00:49.070 back to the deep dive. It's great to have you 00:00:49.070 --> 00:00:51.750 with us today. We were doing something a little 00:00:51.750 --> 00:00:55.109 different and Frankly, I am really excited about 00:00:55.109 --> 00:00:57.090 it. Usually we take a stack of articles, maybe 00:00:57.090 --> 00:00:59.490 a big nonfiction book or some tech reports, and 00:00:59.490 --> 00:01:02.609 we pull out the insights. But today, today we're 00:01:02.609 --> 00:01:04.730 going to medical school, well, nursing school 00:01:04.730 --> 00:01:07.170 specifically. That's right. We're pivoting to 00:01:07.170 --> 00:01:10.730 look at a very specific high stakes area of pediatric 00:01:10.730 --> 00:01:13.030 health care. And honestly, this is some of the 00:01:13.030 --> 00:01:15.129 most complex material you can encounter in a 00:01:15.129 --> 00:01:17.230 clinical setting. We're tackling the pediatric 00:01:17.230 --> 00:01:19.450 immune system. And before you tune out thinking 00:01:19.450 --> 00:01:21.430 this is just going to be a dry biology lecture, 00:01:21.510 --> 00:01:24.170 let me stop you. We're looking at a source specifically 00:01:24.170 --> 00:01:27.010 designed as a, well, a clinical survival guide. 00:01:27.530 --> 00:01:30.109 We're calling this the exam hack session. We 00:01:30.109 --> 00:01:32.329 have a massive stack of notes here covering chapter 00:01:32.329 --> 00:01:35.329 25, which deals with alterations in immunity. 00:01:35.849 --> 00:01:38.090 It really is a survival guide. The material we 00:01:38.090 --> 00:01:40.689 have is dense. It covers everything from kids 00:01:40.689 --> 00:01:44.129 with literally zero immune system to kids whose 00:01:44.129 --> 00:01:46.230 immune systems are overactive and attacking their 00:01:46.230 --> 00:01:49.430 own bodies. It's a whole spectrum of invisible 00:01:49.430 --> 00:01:51.900 warfare happening inside these children. So, 00:01:52.120 --> 00:01:54.260 our mission today is simple. We're applying the 00:01:54.260 --> 00:01:57.200 Pareto Principle, the 80 -20 rule. We want to 00:01:57.200 --> 00:01:59.700 extract the 20 % of the immune concepts that 00:01:59.700 --> 00:02:02.000 are going to answer 80 % of the exam questions 00:02:02.000 --> 00:02:04.439 and, you know, more importantly, keep kids safe 00:02:04.439 --> 00:02:06.719 on the hospital floor. Exactly. We aren't trying 00:02:06.719 --> 00:02:08.979 to memorize the entire textbook line by line. 00:02:08.979 --> 00:02:10.939 That's just not practical. We're looking for 00:02:10.939 --> 00:02:14.000 the patterns. In pediatrics, spotting the pattern 00:02:14.000 --> 00:02:16.120 early before the labs come back, before the crash 00:02:16.120 --> 00:02:18.400 happens, that's the difference between a good 00:02:18.400 --> 00:02:20.639 outcome and a tragedy. And we've got a heavy 00:02:20.639 --> 00:02:23.080 hitters lineup today. We're talking SCID, the 00:02:23.080 --> 00:02:26.219 bubble boy disease, we're talking lupus, juvenile 00:02:26.219 --> 00:02:29.800 arthritis, the terrifying ascending paralysis 00:02:29.800 --> 00:02:32.560 of Guillain -Barre syndrome, and of course anaphylaxis 00:02:32.560 --> 00:02:34.900 and latex allergies. It's a mix of chronic management 00:02:34.900 --> 00:02:36.840 and immediate life -threatening emergencies. 00:02:37.099 --> 00:02:39.360 It covers the genetic, the autoimmune, and the 00:02:39.360 --> 00:02:42.240 environmental. Huge topic. So here is the setup 00:02:42.240 --> 00:02:44.699 for today. I'm gonna be the curious learner. 00:02:44.939 --> 00:02:46.780 I'm the one on the floor who has read the book 00:02:46.780 --> 00:02:48.759 but hasn't seen the patient yet. I'm gonna ask 00:02:48.759 --> 00:02:51.900 the obvious questions. You are the expert. You're 00:02:51.900 --> 00:02:54.259 the pediatric nursing coach. You need to tell 00:02:54.259 --> 00:02:58.159 me what matters and what is just noise. I can 00:02:58.159 --> 00:03:00.300 do that. My goal is to help you synthesize this 00:03:00.300 --> 00:03:02.360 so when you see a question or a patient the answer 00:03:02.360 --> 00:03:04.479 just clicks. We need to bridge that gap between 00:03:04.479 --> 00:03:08.120 textbook theory and bedside reality. Perfect. 00:03:08.759 --> 00:03:10.400 Let's dive into what we're calling the master 00:03:10.400 --> 00:03:13.280 80 -20 map. Before we get into the specific diseases, 00:03:13.580 --> 00:03:15.960 you mentioned there are really only four patterns 00:03:15.960 --> 00:03:18.219 or landscapes we need to understand. Walk me 00:03:18.219 --> 00:03:20.699 through this terrain. Right. If you zoom out, 00:03:21.020 --> 00:03:23.139 pediatric immunology really falls into four buckets 00:03:23.139 --> 00:03:25.639 of risk. If you can identify which bucket your 00:03:25.639 --> 00:03:27.919 patient is in, you know your safety priority 00:03:27.919 --> 00:03:30.240 immediately. It just simplifies the chaos. Okay, 00:03:30.300 --> 00:03:32.000 lay them on me. What's pattern number one? Pattern 00:03:32.000 --> 00:03:34.240 number one is the absent defense. This is the 00:03:34.240 --> 00:03:36.680 infection risk pattern. The prototype here is 00:03:36.680 --> 00:03:39.939 SEID, Severe Combined Immune Deficiency. Absent 00:03:39.939 --> 00:03:43.780 defense. That sounds ominous, like a council 00:03:43.780 --> 00:03:47.620 with no walls. It is exactly that. In this pattern, 00:03:47.800 --> 00:03:50.259 the child simply cannot fight. They have no shield. 00:03:50.699 --> 00:03:53.080 The walls are down, the mode is dry, and the 00:03:53.080 --> 00:03:56.159 gate is wide open. So for the exam and for the 00:03:56.159 --> 00:03:58.699 bedside, the priority is the environment. If 00:03:58.699 --> 00:04:00.539 they can't fight the infection, you have to make 00:04:00.539 --> 00:04:02.740 sure the infection never touches them. It's all 00:04:02.740 --> 00:04:05.080 about strict isolation. So if I see a question 00:04:05.080 --> 00:04:08.080 about absent defense, the answer is almost always 00:04:08.080 --> 00:04:10.300 about keeping things sterile. Correct. You are 00:04:10.300 --> 00:04:12.560 the wall, the nurse, the room, the equipment. 00:04:12.819 --> 00:04:15.620 That becomes the immune system. Right. And the 00:04:15.620 --> 00:04:18.339 can't miss here, the thing that kills the patient 00:04:18.339 --> 00:04:20.839 is recognizing that this is a medical emergency. 00:04:20.939 --> 00:04:22.480 You can't just wait and see. They need a stem 00:04:22.480 --> 00:04:25.360 cell transplant or they die. It's binary. OK. 00:04:25.620 --> 00:04:27.480 Pattern two. Pattern two is the self -attack. 00:04:27.540 --> 00:04:29.240 This is chronic inflammation. We're talking about 00:04:29.240 --> 00:04:32.850 systemic. lupus erythematosus, SLE, and juvenile 00:04:32.850 --> 00:04:35.329 idiopathic arthritis, JIA. So instead of having 00:04:35.329 --> 00:04:38.189 no shield, the shield is bashing them in the 00:04:38.189 --> 00:04:40.110 face. That is a great analogy. It's friendly 00:04:40.110 --> 00:04:42.529 fire. The immune system is hyperactive. It's 00:04:42.529 --> 00:04:44.930 confused and it's attacking the body's own tissues. 00:04:45.949 --> 00:04:48.149 The exam priority here shifts completely. It's 00:04:48.149 --> 00:04:50.610 a balancing act. You have to suppress the immune 00:04:50.610 --> 00:04:53.389 system with drugs to stop the damage, but you 00:04:53.389 --> 00:04:55.350 have to keep them healthy enough to grow and 00:04:55.350 --> 00:04:58.209 develop. And what's the can't miss for this pattern? 00:04:58.430 --> 00:05:01.430 organ damage, and function loss. In lupus, it's 00:05:01.430 --> 00:05:03.709 the kidneys. You have to save the kidneys. In 00:05:03.709 --> 00:05:06.370 JIA, it's the loss of mobility. You're fighting 00:05:06.370 --> 00:05:08.829 to preserve function while taming the immune 00:05:08.829 --> 00:05:11.790 system. Got it. Pattern three. Pattern three 00:05:11.790 --> 00:05:15.129 is the ascending threat. This is strictly neurological 00:05:15.129 --> 00:05:18.110 and airway. The condition is Gaia -Barré syndrome 00:05:18.110 --> 00:05:21.250 or GBS. Ascending is the key word here. It's 00:05:21.250 --> 00:05:23.949 the only key word. The paralysis starts at the 00:05:23.949 --> 00:05:26.670 feet and moves up. The exam priority is tracking 00:05:26.670 --> 00:05:29.269 that direction because, and this is the can't 00:05:29.269 --> 00:05:32.310 miss, as it moves up, what does it hit eventually? 00:05:32.550 --> 00:05:34.750 The lungs. The diaphragm, respiratory failure. 00:05:34.850 --> 00:05:36.949 That's the crash point. You watch the toes to 00:05:36.949 --> 00:05:38.769 save the lungs. OK, that's terrifying because 00:05:38.769 --> 00:05:41.870 it feels like a ticking clock. And pattern four. 00:05:42.129 --> 00:05:45.180 Pattern four is the immediate collapse. This 00:05:45.180 --> 00:05:48.160 is shock. We're talking anaphylaxis and latex 00:05:48.160 --> 00:05:50.879 allergy. This is the speed round. It is. The 00:05:50.879 --> 00:05:52.920 priority is speed of onset. We're talking 5 to 00:05:52.920 --> 00:05:56.259 10 minutes and airway management. The can't miss 00:05:56.259 --> 00:05:58.819 is the administration technique of epinephrine. 00:05:59.540 --> 00:06:02.300 If you hesitate, you lose the airway. There's 00:06:02.300 --> 00:06:04.920 no time to consult a textbook here. Okay, I love 00:06:04.920 --> 00:06:07.500 that framework. Absent defense, self -attack, 00:06:07.699 --> 00:06:10.620 ascending threat, and immediate collapse. Now 00:06:10.620 --> 00:06:12.240 that you have the map, let's zoom in. We're going 00:06:12.240 --> 00:06:14.839 to do a deep dive on each of these, cross -referencing 00:06:14.839 --> 00:06:17.160 the disease process with the developmental impact, 00:06:17.500 --> 00:06:19.660 because this is PEDS and kids aren't just small 00:06:19.660 --> 00:06:22.120 adults. Exactly. You cannot treat the disease 00:06:22.120 --> 00:06:24.579 without treating the development. A four -year 00:06:24.579 --> 00:06:26.579 -old with arthritis is a completely different 00:06:26.579 --> 00:06:28.800 clinical picture than a 40 -year -old with arthritis. 00:06:29.180 --> 00:06:30.959 The stakes are totally different. Let's start 00:06:30.959 --> 00:06:34.470 with the absent defense, SCID. Severe combined 00:06:34.470 --> 00:06:36.529 immune deficiency. Give me the one -line identifier. 00:06:36.910 --> 00:06:39.829 This is the bubble boy disease. It is a potentially 00:06:39.829 --> 00:06:43.050 fatal absence of both T cell and B cell function. 00:06:43.350 --> 00:06:46.410 Okay, let's unpack the patho in plain English. 00:06:47.089 --> 00:06:49.649 I know T cells and B cells are immune things, 00:06:49.689 --> 00:06:51.769 but what's actually happening? Why do we need 00:06:51.769 --> 00:06:54.569 both? Think of the immune system like a highly 00:06:54.569 --> 00:06:58.329 organized military. The T cells are your soldiers. 00:06:58.930 --> 00:07:00.629 They're the infantry that goes out and hunts 00:07:00.629 --> 00:07:03.620 down the intruders. the viruses, the fungi, the 00:07:03.620 --> 00:07:06.579 bacteria. They engage in hand -to -hand combat. 00:07:06.860 --> 00:07:09.500 OK, T cells are the grunts, the front line. Right. 00:07:09.519 --> 00:07:11.420 Now, the B cells are your intelligence officers. 00:07:11.500 --> 00:07:13.879 They remember the intruders. They take a snapshot 00:07:13.879 --> 00:07:16.680 of the enemy and produce antibodies so that if 00:07:16.680 --> 00:07:19.240 that enemy ever shows up again, the response 00:07:19.240 --> 00:07:21.399 is instant. They provide long -term memory and 00:07:21.399 --> 00:07:24.279 protection. And an SCID? You have neither. No 00:07:24.279 --> 00:07:27.120 soldiers, no intel. The child has essentially 00:07:27.120 --> 00:07:29.660 zero immune system. It's not just weak, it's 00:07:29.660 --> 00:07:31.800 absent. When do we see this? Does the baby come 00:07:31.800 --> 00:07:34.040 out sick? That's the tricky part, and that's 00:07:34.040 --> 00:07:37.680 the exam trap. Usually, no. SEID typically presents 00:07:37.680 --> 00:07:40.000 within the first six months of life, but rarely 00:07:40.000 --> 00:07:42.519 in the first month. Why the delay? If they have 00:07:42.519 --> 00:07:44.180 a new immune system, shouldn't they get sick 00:07:44.180 --> 00:07:46.199 the moment they take their first breath? You 00:07:46.199 --> 00:07:47.819 would think so, but they have a borrowed shield. 00:07:48.720 --> 00:07:52.079 Maternal antibodies. Mom passes on some protection, 00:07:52.579 --> 00:07:56.120 specifically IgG, through the placenta. That 00:07:56.120 --> 00:07:58.680 borrowed immunity protects the infant for the 00:07:58.680 --> 00:08:01.100 first three to four months. Ah, so they are running 00:08:01.100 --> 00:08:04.199 on mom's battery power. Exactly. But as that 00:08:04.199 --> 00:08:06.480 battery fades around month four or five or six, 00:08:06.839 --> 00:08:09.259 the infant is left defenseless. That's when the 00:08:09.259 --> 00:08:12.519 chronic severe infections start. Okay, so let's 00:08:12.519 --> 00:08:15.199 hit the need to know core. What are the top findings 00:08:15.199 --> 00:08:17.680 we're looking for clinically? You're looking 00:08:17.680 --> 00:08:20.560 for a young infant, let's say five months old, 00:08:21.000 --> 00:08:23.589 with a history of chronic infections. And I don't 00:08:23.589 --> 00:08:26.290 mean a sniffle. I mean ear infections that antibiotics 00:08:26.290 --> 00:08:29.569 won't touch. Persistent oral thrush, that white 00:08:29.569 --> 00:08:31.670 coating in the mouth that just won't go away. 00:08:32.029 --> 00:08:34.289 Severe diaper rashes, pneumonia. That's just 00:08:34.289 --> 00:08:36.570 one thing after another, a constant battle. Yes. 00:08:36.690 --> 00:08:39.750 And specifically, we look for opportunistic infections. 00:08:39.909 --> 00:08:42.190 These are bugs that wouldn't hurt you or me because 00:08:42.190 --> 00:08:43.990 our immune systems would squash them instantly. 00:08:44.549 --> 00:08:47.610 But in a SEID baby, they can be lethal. Think 00:08:47.610 --> 00:08:50.049 things like pneumocystis pneumonia. And how do 00:08:50.049 --> 00:08:52.580 we confirm it? What's the diagnostic path? It's 00:08:52.580 --> 00:08:55.279 genetic. There are five different types classified 00:08:55.279 --> 00:08:58.639 by the exact genetic defect X -linked or autosomal 00:08:58.639 --> 00:09:01.659 recessive, but the diagnosis comes down to looking 00:09:01.659 --> 00:09:04.700 at the blood and seeing absent T and B cells. 00:09:05.279 --> 00:09:07.399 The lymphocyte count will be incredibly low. 00:09:07.840 --> 00:09:09.500 In many places now, it's actually part of the 00:09:09.500 --> 00:09:11.460 newborn screen, so we can catch it before they 00:09:11.460 --> 00:09:13.580 even get sick. You mentioned earlier this is 00:09:13.580 --> 00:09:16.440 fatal without treatment. What is the intervention? 00:09:16.899 --> 00:09:20.960 The immediate bridge is IVIG intravenous immunoglobulin. 00:09:21.179 --> 00:09:24.080 We are literally infusing them with someone else's 00:09:24.080 --> 00:09:26.179 antibodies to buy time. We're refilling that 00:09:26.179 --> 00:09:29.799 battery. But the cure, the only cure, is a hematopoietic 00:09:29.799 --> 00:09:33.100 stem cell transplant, an HSCT. We have to replace 00:09:33.100 --> 00:09:35.100 their bone marrow so they can build their own 00:09:35.100 --> 00:09:37.279 immune system. Here is a question for the exam 00:09:37.279 --> 00:09:39.379 side of things. If I see a question describing 00:09:39.379 --> 00:09:42.519 a rare X -link disorder with absent B and T cells, 00:09:42.879 --> 00:09:45.519 I shouldn't hesitate. Don't hesitate. It's SCID. 00:09:45.899 --> 00:09:47.860 And remember, X -link means it's much more common 00:09:47.860 --> 00:09:50.450 in boys. Now let's talk development. Because 00:09:50.450 --> 00:09:52.529 if I'm a nurse caring for a baby who has to be 00:09:52.529 --> 00:09:54.990 in strict isolation, that sounds like a developmental 00:09:54.990 --> 00:09:57.929 nightmare. It is. Think about how an infant learns. 00:09:58.590 --> 00:10:02.009 They learn through touch. through putting things 00:10:02.009 --> 00:10:04.070 in their mouth, through seeing facial expressions. 00:10:04.389 --> 00:10:07.049 If everyone entering the room is in a gown, mask, 00:10:07.129 --> 00:10:09.970 and gloves, and the baby is kept in a sterile 00:10:09.970 --> 00:10:12.110 bubble. They miss out on bonding. They miss out 00:10:12.110 --> 00:10:14.250 on the human connection, all those little cues. 00:10:14.450 --> 00:10:17.149 Huge risk for failure to thrive. Not just physically, 00:10:17.269 --> 00:10:19.350 but socially. They can become withdrawn. They 00:10:19.350 --> 00:10:21.909 don't learn those early social interaction skills. 00:10:21.990 --> 00:10:24.110 So what's the nursing action? How do we fix that? 00:10:24.149 --> 00:10:26.350 What can we actually do? We have to facilitate 00:10:26.350 --> 00:10:28.860 sterile bonding. We encourage parents to be in 00:10:28.860 --> 00:10:31.500 the room, but we teach them rigorous scrub techniques. 00:10:31.720 --> 00:10:33.940 We use sterile toys. We can't just leave them 00:10:33.940 --> 00:10:36.139 in the crib. We have to provide sensory stimulation 00:10:36.139 --> 00:10:39.500 safely. We talk to them. We play music. We use 00:10:39.500 --> 00:10:42.259 high contrast cards. We find ways to interact 00:10:42.259 --> 00:10:44.299 through the barrier. It's a balance of keeping 00:10:44.299 --> 00:10:47.240 them alive versus keeping them, well, human. 00:10:47.600 --> 00:10:50.100 Precisely. And for the nice -to -know category, 00:10:50.639 --> 00:10:52.840 while there are different genetic types, the 00:10:52.840 --> 00:10:55.500 clinical management is the consensus. Protect 00:10:55.500 --> 00:10:58.580 the child with isolation, bridge with IVAG, and 00:10:58.580 --> 00:11:01.259 cure with a transplant. That's the core pathway. 00:11:01.460 --> 00:11:04.919 Got it. Let's move to pattern two, the self -attack. 00:11:05.159 --> 00:11:08.679 We'll start with SLE. Systemic lupus erythematosus. 00:11:08.799 --> 00:11:11.620 What's the identifier here? The butterfly disease. 00:11:12.279 --> 00:11:15.179 It's a multi -system autoimmune condition with 00:11:15.179 --> 00:11:17.679 unpredictable flares. Multi -system is a word 00:11:17.679 --> 00:11:19.899 that scares students. It means it's everywhere. 00:11:20.100 --> 00:11:22.419 It means the body creates antibodies against 00:11:22.419 --> 00:11:25.970 its own DNA and tissues. And since your DNA is 00:11:25.970 --> 00:11:28.710 in every cell, the inflammation can happen anywhere 00:11:28.710 --> 00:11:31.850 there's connective tissue. Joints, skin, kidneys, 00:11:32.129 --> 00:11:34.870 brain, heart, you name it. But the hallmark, 00:11:34.990 --> 00:11:37.490 the thing that screams lupus on a test? The malarra 00:11:37.490 --> 00:11:39.870 rash. Yeah. A red rash that spreads across the 00:11:39.870 --> 00:11:42.009 cheeks and bridge of the nose in the shape of 00:11:42.009 --> 00:11:44.529 a butterfly. It's very distinctive. Okay. So, 00:11:44.590 --> 00:11:46.929 need to know. Top findings. Aside from the rash, 00:11:46.970 --> 00:11:48.750 you're looking for a course of remission and 00:11:48.750 --> 00:11:51.200 exacerbation. They have quiet periods and then 00:11:51.200 --> 00:11:54.899 flares. So a kid might have joint pain, a low 00:11:54.899 --> 00:11:56.799 -grade fever, and that rash for a few weeks and 00:11:56.799 --> 00:11:58.860 then goes away. What triggers a flare? What makes 00:11:58.860 --> 00:12:01.240 it come back? Stress is a big one. Any kind of 00:12:01.240 --> 00:12:03.960 infection. But a huge exam point is sunlight. 00:12:04.480 --> 00:12:07.379 UV exposure can trigger a loop as flare. These 00:12:07.379 --> 00:12:09.980 kids need to be very careful in the sun. Sun's 00:12:09.980 --> 00:12:12.679 green, hats, long sleeves. And the treatment 00:12:12.679 --> 00:12:14.779 isn't one size fits all, right? I imagine it's 00:12:14.779 --> 00:12:17.379 pretty complex. No. It's stratified by severity. 00:12:18.039 --> 00:12:20.899 If it's mild to moderate, mostly joint pain or 00:12:20.899 --> 00:12:24.200 skin issues, we use NSAIDs and maybe low -dose 00:12:24.200 --> 00:12:26.700 corticosteroids. We might use anti -malarials 00:12:26.700 --> 00:12:29.179 like hydroxychloroquine, which is surprisingly 00:12:29.179 --> 00:12:31.279 effective for controlling the skin rashes and 00:12:31.279 --> 00:12:33.919 joint pain. But if it's severe, if it's attacking 00:12:33.919 --> 00:12:36.100 major organs? If the organs are being attacked, 00:12:36.320 --> 00:12:38.700 specifically the kidneys or the brain, we go 00:12:38.700 --> 00:12:41.059 to high -dose corticosteroids and immunosuppressives, 00:12:41.259 --> 00:12:43.360 things like mycophenolate or cyclophosphamide. 00:12:43.519 --> 00:12:45.639 We have to bring out the big guns to stop the 00:12:45.639 --> 00:12:47.600 organ damage. Let's talk about that exam tip 00:12:47.600 --> 00:12:49.379 you mentioned earlier regarding the can't miss, 00:12:49.500 --> 00:12:53.500 the kidneys. Yes. Lupus nephritis. This is the 00:12:53.500 --> 00:12:56.500 major cause of morbidity and mortality in pediatric 00:12:56.500 --> 00:12:59.240 lupus. If a child with lupus starts having high 00:12:59.240 --> 00:13:03.179 blood pressure or dark foamy urine, that's hematuria 00:13:03.179 --> 00:13:05.960 and protein area or swelling, edema in the face 00:13:05.960 --> 00:13:09.090 and hands, that is the priority. The rash is 00:13:09.090 --> 00:13:11.750 annoying. The kidney failure is deadly. So if 00:13:11.750 --> 00:13:13.490 I'm the nurse, I'm watching the urine output 00:13:13.490 --> 00:13:15.909 and the blood pressure like a hawk. Daily weights, 00:13:16.149 --> 00:13:18.509 too. Absolutely. Yeah. Strict intake and output. 00:13:18.889 --> 00:13:21.350 Daily weights. You are monitoring for renal failure. 00:13:21.610 --> 00:13:24.210 Now development. Lupus often hits in adolescence, 00:13:24.230 --> 00:13:26.129 right? It's much more common in girls, often 00:13:26.129 --> 00:13:28.009 presenting around puberty. Hormones seem to play 00:13:28.009 --> 00:13:30.009 a role. And think about being a 15 -year -old 00:13:30.009 --> 00:13:32.870 girl. Oh, man. Body image is everything. Fitting 00:13:32.870 --> 00:13:35.370 in is everything. Exactly. You have this butterfly 00:13:35.370 --> 00:13:37.269 rash on your face. You might be losing hair, 00:13:37.330 --> 00:13:39.629 which is called alopecia. Yeah. And the treatment, 00:13:40.149 --> 00:13:43.230 high -dose steroids. Which cause moon face and 00:13:43.230 --> 00:13:46.690 weight gain and acne, the trifecta of teenage 00:13:46.690 --> 00:13:49.330 nightmares. It is devastating. The non -compliance 00:13:49.330 --> 00:13:51.309 rate in adolescents with lupus is incredibly 00:13:51.309 --> 00:13:53.669 high because they hate the side effects of the 00:13:53.669 --> 00:13:55.950 drugs. They would rather feel sick than look 00:13:55.950 --> 00:13:58.990 different. That's a huge nursing insight. If 00:13:58.990 --> 00:14:01.570 you have a teen whose lupus is flaring, and they 00:14:01.570 --> 00:14:03.750 swear they are fine, ask if they're actually 00:14:03.750 --> 00:14:05.809 taking their meds. Right. And you have to approach 00:14:05.809 --> 00:14:08.230 it without judgment. I know the prednisone makes 00:14:08.230 --> 00:14:11.190 you feel puffy. It sucks. But we need to save 00:14:11.190 --> 00:14:14.370 your kidneys. It's a constant negotiation. And 00:14:14.370 --> 00:14:16.879 school is another factor. The fatigue during 00:14:16.879 --> 00:14:20.179 a flare is real. It's not just, I'm tired. It's 00:14:20.179 --> 00:14:22.720 bone -deep exhaustion. They might need a modified 00:14:22.720 --> 00:14:25.299 schedule, late starts or rest periods. They aren't 00:14:25.299 --> 00:14:28.179 being lazy. Their body is fighting a civil war. 00:14:28.360 --> 00:14:30.139 Okay, let's stay in the self -attack pattern 00:14:30.139 --> 00:14:33.779 but move to the joints. Juvenile Adiopathic Arthritis, 00:14:34.159 --> 00:14:36.919 or JIA. Is this just grandma's arthritis but 00:14:36.919 --> 00:14:39.879 in a kid? Definitely not. Grandma's arthritis 00:14:39.879 --> 00:14:42.820 is osteoarthritis wear and tear. The cartilage 00:14:42.820 --> 00:14:46.230 wears down over 70 years. JIA is autoimmune. 00:14:46.409 --> 00:14:48.809 The immune system is actively targeting the synovial 00:14:48.809 --> 00:14:51.070 fluid in the joints, causing massive inflammation. 00:14:51.570 --> 00:14:54.169 It's an attack, not wear. So the joint is swollen, 00:14:54.490 --> 00:14:57.929 hot, red, and painful. Exactly. And unlike grandma's 00:14:57.929 --> 00:14:59.870 arthritis, which gets worse the more she uses 00:14:59.870 --> 00:15:02.570 it, JIA stiffness is often worse in the morning 00:15:02.570 --> 00:15:04.889 after inactivity. We call it morning gelling. 00:15:05.210 --> 00:15:07.409 What's the goal here? What are we trying to achieve? 00:15:07.710 --> 00:15:10.230 The priority goal is to promote a normal lifestyle. 00:15:10.570 --> 00:15:12.379 That's what you're looking for in an exam. That 00:15:12.379 --> 00:15:14.639 seems ambitious if your joints hurt all the time. 00:15:14.820 --> 00:15:17.580 It is, but it's critical. If a child with JIA 00:15:17.580 --> 00:15:20.460 stops moving because it hurts, the joints stiffen 00:15:20.460 --> 00:15:22.700 up, they get contractures where the joint freezes 00:15:22.700 --> 00:15:25.379 in a bent position, they lose muscle mass. So 00:15:25.379 --> 00:15:28.159 the management is pain control plus maintenance 00:15:28.159 --> 00:15:30.139 and mobility. It's move it or lose it. Literally. 00:15:30.379 --> 00:15:32.379 We want them in physical therapy, occupational 00:15:32.379 --> 00:15:35.899 therapy, playing, going to school. So the meds, 00:15:36.019 --> 00:15:39.360 we see a similar list to lupus. Similar. NKIs 00:15:39.360 --> 00:15:42.399 like naproxen or ibuprofen are first line for 00:15:42.399 --> 00:15:45.299 inflammation. Corticosteroids for flares may 00:15:45.299 --> 00:15:47.460 be injected right into a joint to calm it down. 00:15:47.940 --> 00:15:51.000 But here we see a heavy reliance on DR's disease 00:15:51.000 --> 00:15:53.639 -modifying anti -traumatic drugs. Things like 00:15:53.639 --> 00:15:56.899 methotrexate and the biologics like etanercept. 00:15:57.080 --> 00:15:58.899 We'll get to the specifics of those in the med 00:15:58.899 --> 00:16:01.740 module, but for the JIA section, what's the need 00:16:01.740 --> 00:16:04.539 to know exam tip regarding outcomes? The goal 00:16:04.539 --> 00:16:07.500 isn't just stop the pain. If an exam question 00:16:07.500 --> 00:16:10.500 asks what the outcome goal is, it's participation 00:16:10.500 --> 00:16:12.980 in school and activities. It's keeping them moving. 00:16:13.399 --> 00:16:16.159 The answer isn't pain score of zero, it's child 00:16:16.159 --> 00:16:19.019 attended school all day. Developmentally, how 00:16:19.019 --> 00:16:22.100 does this play out? What are the risks? Physically, 00:16:22.240 --> 00:16:24.279 we worry about delayed motor skills. If a toddler 00:16:24.279 --> 00:16:26.519 has JIA in their knees, they might not want to 00:16:26.519 --> 00:16:28.519 walk. They might revert to crawling. That's a 00:16:28.519 --> 00:16:31.860 red flag. It can also affect bone growth. One 00:16:31.860 --> 00:16:34.059 leg might grow longer than the other if the knee 00:16:34.059 --> 00:16:36.240 joint has chronic inflammation. And socially. 00:16:36.480 --> 00:16:39.299 Recess. Sports. If you can't keep up with your 00:16:39.299 --> 00:16:41.659 peers, you get isolated. You become this sick 00:16:41.659 --> 00:16:43.580 kid who sits on the bench. It could really impact 00:16:43.580 --> 00:16:46.659 their self -esteem. So a nursing action might 00:16:46.659 --> 00:16:49.179 be coordinating meds around school? Exactly. 00:16:49.580 --> 00:16:51.700 Give the NSA aids or a warm bath in the morning. 00:16:52.120 --> 00:16:54.179 The heat helps loosen the stiff joints so they 00:16:54.179 --> 00:16:56.340 aren't hobbling when they get to school. Make 00:16:56.340 --> 00:16:58.620 sure pain control is active during recess time. 00:16:58.960 --> 00:17:01.620 It's about planning ahead to maximize function. 00:17:02.039 --> 00:17:04.319 And there is a weird nice -to -know complication 00:17:04.319 --> 00:17:09.059 with JA involving the I's. Yes, uveitis or iridocyclitis. 00:17:09.700 --> 00:17:12.500 Inflammation of the eye. It can be totally asymptomatic, 00:17:12.539 --> 00:17:15.660 but can cause adhesions and visual loss, even 00:17:15.660 --> 00:17:19.059 blindness if untreated. These kids need regular 00:17:19.059 --> 00:17:21.980 slit -lamp eye exams with an ophthalmologist, 00:17:22.160 --> 00:17:24.299 even if their joints feel fine. It's a silent 00:17:24.299 --> 00:17:27.920 threat. That is a great nugget. Moving on, pattern 00:17:27.920 --> 00:17:31.279 three, the ascending threat, Guillain -Barré 00:17:31.279 --> 00:17:34.220 syndrome, GBS. This is one of the most distinctive 00:17:34.220 --> 00:17:36.700 patterns in medicine. Once you see it, you never 00:17:36.700 --> 00:17:39.279 forget it. One -liner. The ascending paralysis 00:17:39.279 --> 00:17:41.599 that follows a virus. Okay, break down the timeline. 00:17:41.720 --> 00:17:43.720 You said it follows a virus. Yes. The history 00:17:43.720 --> 00:17:46.400 taking is key here. The child usually had a stomach 00:17:46.400 --> 00:17:48.799 bug like Campylobacter or a respiratory infection 00:17:48.799 --> 00:17:50.839 about two or three weeks ago. They got better, 00:17:51.279 --> 00:17:53.140 but the immune system got revved up to fight 00:17:53.140 --> 00:17:55.559 the virus and then it got confused. It's called 00:17:55.559 --> 00:17:58.480 molecular mimicry. Confused how? It starts attacking 00:17:58.480 --> 00:18:00.960 the myelin sheath of the peripheral nerves. The 00:18:00.960 --> 00:18:02.839 proteins on the nerve sheath look similar to 00:18:02.839 --> 00:18:04.779 the proteins from the virus. The myelin sheath 00:18:04.779 --> 00:18:07.089 is like the insulation on a wire, right? Correct. 00:18:07.670 --> 00:18:10.390 It helps the electrical signal travel fast. Without 00:18:10.390 --> 00:18:12.490 it, the signal leaks out or moves too slowly. 00:18:12.809 --> 00:18:15.309 The nerve stops working. It's called demyelination. 00:18:15.450 --> 00:18:18.869 And the direction is key. Ascending. Always ascending. 00:18:19.170 --> 00:18:21.250 It starts in the toes and feet. The child might 00:18:21.250 --> 00:18:23.289 complain of tingling or their legs feeling heavy. 00:18:23.650 --> 00:18:25.750 Then they start tripping. Then they can't climb 00:18:25.750 --> 00:18:27.930 stairs. Then they can't walk. No, it just keeps 00:18:27.930 --> 00:18:32.430 moving up. Legs. Then hips. Then torso. Then 00:18:32.430 --> 00:18:36.160 arms. Then face. which affects swallowing and 00:18:36.160 --> 00:18:38.940 facial expressions. And the need to know crash 00:18:38.940 --> 00:18:41.440 point. Respiratory failure. If that paralysis 00:18:41.440 --> 00:18:43.839 reaches the diaphragm, which is a muscle controlled 00:18:43.839 --> 00:18:46.740 by peripheral nerves, they cannot breathe. They 00:18:46.740 --> 00:18:48.779 literally suffocate because their muscles can't 00:18:48.779 --> 00:18:51.119 pull air in. So if I have a patient admitted 00:18:51.119 --> 00:18:54.279 with weakness in legs suspected of GBS, what 00:18:54.279 --> 00:18:56.400 is my priority assessment? Am I checking their 00:18:56.400 --> 00:18:59.319 reflexes? Reflexes will be absent. Yes, that's 00:18:59.319 --> 00:19:03.200 a diagnostic clue. Aeroflexia. But your priority 00:19:03.200 --> 00:19:06.759 is respiratory effort and swallowing. You are 00:19:06.759 --> 00:19:08.920 watching for the ascent. You're checking their 00:19:08.920 --> 00:19:11.420 respiratory rate, their oxygen saturation, and 00:19:11.420 --> 00:19:13.339 asking them to cough. Can they manage their own 00:19:13.339 --> 00:19:16.140 saliva? You need to anticipate the crash before 00:19:16.140 --> 00:19:18.420 it happens. You keep the intubation kit nearby. 00:19:18.859 --> 00:19:21.019 What is the treatment? Do we give antibiotics? 00:19:21.880 --> 00:19:24.420 No, it's not an active infection anymore. It's 00:19:24.420 --> 00:19:26.960 an immune response. The management is symptomatic, 00:19:27.000 --> 00:19:29.799 supporting the body while the nerves heal. We 00:19:29.799 --> 00:19:32.359 treat the immune response with high -dose IVIG 00:19:32.359 --> 00:19:35.779 or plasmapheresis. Plasmapheresis is like dialysis 00:19:35.779 --> 00:19:37.859 for the blood. Sort of. It filters the blood 00:19:37.859 --> 00:19:39.740 to remove the bad antibodies that are attacking 00:19:39.740 --> 00:19:42.140 the nerves, but mostly it's supportive care. 00:19:42.480 --> 00:19:44.960 Ventilation, nutrition, skin care, preventing 00:19:44.960 --> 00:19:47.599 blood clots. And the timeline for recovery. It 00:19:47.599 --> 00:19:51.059 is slow. Weeks to months, sometimes years. And 00:19:51.059 --> 00:19:54.019 interestingly, it heals in reverse. It descends. 00:19:54.299 --> 00:19:56.259 Function returns from the head down to the toes. 00:19:56.660 --> 00:19:59.240 The arms get better before the legs. Let's talk 00:19:59.240 --> 00:20:01.700 development. Imagine a four -year -old who was 00:20:01.700 --> 00:20:03.900 running around yesterday and is bedbound today. 00:20:04.180 --> 00:20:06.960 It is terrifying for them. Yeah. High anxiety. 00:20:07.700 --> 00:20:10.329 Fear. Their brain is working perfectly. They 00:20:10.329 --> 00:20:13.130 are fully conscious, but they are trapped in 00:20:13.130 --> 00:20:15.869 a body that won't move. Regression must be huge. 00:20:15.950 --> 00:20:18.190 It is. A potty -trained child might start wetting 00:20:18.190 --> 00:20:20.009 the bed because they lose bladder control. They 00:20:20.009 --> 00:20:22.289 might want to pacify her again. They lose their 00:20:22.289 --> 00:20:24.250 independence completely. And looking long -term? 00:20:24.430 --> 00:20:27.349 Missed school. A ton of rehab to relearn motor 00:20:27.349 --> 00:20:29.789 milestones. They might have to learn how to walk 00:20:29.789 --> 00:20:31.990 again, how to ride again. The nurse needs to 00:20:31.990 --> 00:20:34.190 be the cheerleader here, validating their fear 00:20:34.190 --> 00:20:37.480 but tracking their progress. Look! You wiggled 00:20:37.480 --> 00:20:40.119 your big toe today. That's huge. Okay. Pattern 00:20:40.119 --> 00:20:42.980 four, the immediate collapse. Yeah. Anaphylaxis 00:20:42.980 --> 00:20:45.359 and latex allergy. This is the hyper response. 00:20:45.579 --> 00:20:48.240 This is the body overreacting to a specific trigger. 00:20:48.480 --> 00:20:50.940 Patho in plain language. The body sees an allergen 00:20:50.940 --> 00:20:54.779 latex, bee sting, peanut, and the immune system, 00:20:55.079 --> 00:20:57.839 specifically IgE antibodies, triggers mast cells 00:20:57.839 --> 00:20:59.799 to dump a massive amount of histamine and other 00:20:59.799 --> 00:21:02.380 chemicals. Histamine causes two main things, 00:21:02.859 --> 00:21:05.920 vasodilation and bronchoconstriction. Vasodilation 00:21:05.920 --> 00:21:09.460 means Blood vessels widen and become leaky. Fluid 00:21:09.460 --> 00:21:12.119 leaks out into the tissues. Blood pressure plummets. 00:21:12.539 --> 00:21:15.160 That is shock. And bronchoconstriction means? 00:21:15.319 --> 00:21:17.400 The smooth muscles around the airways tighten. 00:21:17.859 --> 00:21:21.119 The airway swells. No air gets in. A deadly combination. 00:21:21.319 --> 00:21:23.819 Within five to ten minutes. It's incredibly fast. 00:21:24.059 --> 00:21:27.339 So, need to know. Symptoms? Hives. We call that 00:21:27.339 --> 00:21:30.680 urticaria. Wheezing, cough, shortness of breath, 00:21:31.039 --> 00:21:34.289 nasal congestion. But look for the feeling. The 00:21:34.289 --> 00:21:37.029 sense of impending doom. Kids often say something 00:21:37.029 --> 00:21:40.089 feels wrong, or my throat feels itchy, or my 00:21:40.089 --> 00:21:41.890 tongue feels thick. You have to listen to that. 00:21:42.250 --> 00:21:44.470 And the latex specifics. The source material 00:21:44.470 --> 00:21:48.029 highlights this. Why latex? Latex is a specific 00:21:48.029 --> 00:21:50.529 allergy. Often seen in kids who have had multiple 00:21:50.529 --> 00:21:52.769 surgeries, like children with spina bifida, because 00:21:52.769 --> 00:21:55.029 they've been exposed to so much latex tubing 00:21:55.029 --> 00:21:57.390 and gloves early in life, their body becomes 00:21:57.390 --> 00:21:59.450 sensitized to it. And the priority intervention. 00:21:59.549 --> 00:22:02.289 There's only one. Right. Epinephrine. Yeah. The 00:22:02.289 --> 00:22:04.579 EpiPen. It's the only thing that will reverse 00:22:04.579 --> 00:22:07.099 both the vasodilation and the bronchoconstriction. 00:22:07.299 --> 00:22:08.880 Do we wait to see if it gets worse? Maybe get 00:22:08.880 --> 00:22:11.880 some Benadryl first. Never. If there is airway 00:22:11.880 --> 00:22:14.279 involvement or circulatory collapse, you give 00:22:14.279 --> 00:22:17.480 the epi. Better to give it and not need it than 00:22:17.480 --> 00:22:19.980 need it and be too late. Antihistamines like 00:22:19.980 --> 00:22:22.619 Benadryl are not enough for anaphylaxis. They 00:22:22.619 --> 00:22:24.799 are way too slow and they don't support blood 00:22:24.799 --> 00:22:27.140 pressure. Developmentally, how does a severe 00:22:27.140 --> 00:22:30.789 allergy affect a kid? It creates fear. a constant 00:22:30.789 --> 00:22:34.710 low -level anxiety, fear of food, fear of birthday 00:22:34.710 --> 00:22:37.430 parties, fear of the environment. Can I eat this 00:22:37.430 --> 00:22:40.390 cupcake? Will it kill me? So education is the 00:22:40.390 --> 00:22:42.569 intervention. Teaching the child age appropriately 00:22:42.569 --> 00:22:45.150 how to avoid triggers, teaching the parents how 00:22:45.150 --> 00:22:47.910 to read labels, and teaching everyone, the child, 00:22:48.049 --> 00:22:50.210 parents, school nurse, teachers, how to use the 00:22:50.210 --> 00:22:53.049 auto injector. Blue to the sky, orange to the 00:22:53.049 --> 00:22:55.269 thigh. Okay, we've covered the diseases. Now 00:22:55.269 --> 00:22:57.250 I want to move to the medication module. We have 00:22:57.250 --> 00:23:00.029 a specific list of drugs from Chapter 25. I want 00:23:00.029 --> 00:23:02.069 to do a rapid -fire review, but specifically 00:23:02.069 --> 00:23:04.390 focused on the pediatric pearls, the stuff that 00:23:04.390 --> 00:23:06.890 is different for kids. Let's do it. First up, 00:23:07.289 --> 00:23:10.250 5E immunoglobulin, IVIG. We mentioned this for 00:23:10.250 --> 00:23:12.549 SCID and GBS. Right. It's either replacing the 00:23:12.549 --> 00:23:14.809 defense or modulating the immune system. What's 00:23:14.809 --> 00:23:16.910 the PD -specific pearl? What do I need to watch 00:23:16.910 --> 00:23:19.599 for? The administration. You have to watch these 00:23:19.599 --> 00:23:22.460 kids like a hawk during the infusion. Vitals 00:23:22.460 --> 00:23:25.619 every 15 minutes at the start. Reactions, fever, 00:23:26.039 --> 00:23:29.180 chills, headache, nausea, can happen fast. In 00:23:29.180 --> 00:23:31.920 a baby with SCID, that reaction can be destabilizing. 00:23:32.680 --> 00:23:35.599 Also, hydration is key. IVG is thick. It can 00:23:35.599 --> 00:23:37.819 be hard on the kidneys. They need to be well 00:23:37.819 --> 00:23:41.640 hydrated before you even start. Next, corticosteroids. 00:23:42.339 --> 00:23:45.380 Prednisone. We use this for lupus and JIA. The 00:23:45.380 --> 00:23:47.660 mechanism of action is anti -inflammatory and 00:23:47.660 --> 00:23:49.759 ameosuppressive. It puts out the fire. Petty 00:23:49.759 --> 00:23:51.980 pearl. Growth. Long -term steroid use stunts 00:23:51.980 --> 00:23:54.720 height. It affects bone density, leading to osteoporosis 00:23:54.720 --> 00:23:57.180 later, and it causes that Cushingoid appearance, 00:23:57.319 --> 00:23:59.160 the moon face, the buffalo hump, the central 00:23:59.160 --> 00:24:01.720 obesity. So if a parent asks, will this stunt 00:24:01.720 --> 00:24:04.859 his growth? The honest answer is it might, but 00:24:04.859 --> 00:24:06.619 we weigh that against the organ damage from the 00:24:06.619 --> 00:24:09.730 lupus. It's a trade -off. Also, Safety, steroids, 00:24:09.869 --> 00:24:11.869 vasconfection. A kid on steroids might have a 00:24:11.869 --> 00:24:14.369 raging infection, but no fever. The usual alarm 00:24:14.369 --> 00:24:16.549 bells don't ring. You have to be hypervigilant 00:24:16.549 --> 00:24:18.670 for subtle signs of sickness, like just being 00:24:18.670 --> 00:24:23.049 more tired or irritable. Third, NSAIDs, ibuprofen, 00:24:23.190 --> 00:24:27.690 naproxen, for mild lupus and JIA. Goal is pain 00:24:27.690 --> 00:24:30.529 control to allow mobility. They reduce inflammation. 00:24:30.710 --> 00:24:33.549 T .D. Pearl, GI upset. Kids often won't say, 00:24:33.569 --> 00:24:35.890 I have heartburn. They'll just refuse to eat 00:24:35.890 --> 00:24:39.200 or say their tummy hurts. Always give NSAIDs 00:24:39.200 --> 00:24:42.240 with food or milk and watch for easy bruising 00:24:42.240 --> 00:24:45.220 as they can affect platelets slightly. And never, 00:24:45.259 --> 00:24:47.980 ever give aspirin to a child with a viral illness 00:24:47.980 --> 00:24:53.069 because of the risk of Ray's syndrome. Methotrexate, 00:24:53.250 --> 00:24:55.750 etanercept. These are the heavy hitters for JIA. 00:24:56.029 --> 00:24:58.269 These suppress the immune system significantly. 00:24:58.670 --> 00:25:00.769 Methotrexate is actually a chemo drug used in 00:25:00.769 --> 00:25:03.710 lower doses for arthritis. Etanercept is a biologic 00:25:03.710 --> 00:25:06.150 that blocks a specific inflammatory protein called 00:25:06.150 --> 00:25:08.819 TNF -alpha. The exam warning. What's the biggest 00:25:08.819 --> 00:25:10.759 danger? If a child on methotrexate develops a 00:25:10.759 --> 00:25:12.640 fever, it is a medical emergency. They are at 00:25:12.640 --> 00:25:14.359 risk for sepsis. They don't have the reserves 00:25:14.359 --> 00:25:16.079 to fight it. You don't just give Tylenol and 00:25:16.079 --> 00:25:18.839 weight. You go to the ER for a full workup. Also, 00:25:19.039 --> 00:25:21.119 for adolescent girls, methotrexate is teratogenic, 00:25:21.500 --> 00:25:23.319 causes severe birth defects. You have to talk 00:25:23.319 --> 00:25:25.319 about pregnancy prevention, which is an awkward 00:25:25.319 --> 00:25:28.519 but necessary conversation. Finally, epinephrine. 00:25:28.859 --> 00:25:32.279 For anaphylaxis, it's a non -selective adrenergic 00:25:32.279 --> 00:25:36.180 agonist teaching the child. Even a young child 00:25:36.180 --> 00:25:39.559 can be taught that the pin is their friend. And 00:25:39.559 --> 00:25:41.720 parents need to know it goes in the outer thigh, 00:25:42.119 --> 00:25:44.480 the vastus lateralis muscle, and you have to 00:25:44.480 --> 00:25:47.119 hold it there. Hold it for how long? Count to 00:25:47.119 --> 00:25:49.400 three or ten, depending on the brand, but hold 00:25:49.400 --> 00:25:52.099 it firmly in place. Don't just jab and pull. 00:25:52.460 --> 00:25:54.660 You need to ensure the full ghost is delivered 00:25:54.660 --> 00:25:57.920 into the muscle. And always call 911 after using 00:25:57.920 --> 00:26:00.500 it, because a second reaction can happen. Okay, 00:26:00.579 --> 00:26:02.299 we're in the home stretch. I want to do some 00:26:02.299 --> 00:26:04.339 cross -linking. We've hinted at these, but let's 00:26:04.339 --> 00:26:06.660 make the connections explicit. Great. This is 00:26:06.660 --> 00:26:08.599 where the patterns really come together. Connection 00:26:08.599 --> 00:26:12.170 one. The latex food connection. Why do we care 00:26:12.170 --> 00:26:15.210 about food if the kid is allergic to latex gloves? 00:26:15.549 --> 00:26:17.589 Because of cross -reactivity. The proteins in 00:26:17.589 --> 00:26:20.130 latex look very similar to the proteins in certain 00:26:20.130 --> 00:26:23.029 foods. It's a case of mistaken identity by the 00:26:23.029 --> 00:26:24.809 immune system. Which foods are we talking about? 00:26:25.009 --> 00:26:27.289 We call it the tropical fruit salad. Bananas, 00:26:27.589 --> 00:26:30.890 avocados, kiwis, chestnuts, papaya. So if I have 00:26:30.890 --> 00:26:33.049 a latex -allergic kid, I'm taking the banana 00:26:33.049 --> 00:26:36.170 off their lunch tray. Absolutely. You treat those 00:26:36.170 --> 00:26:38.910 foods as potential allergens. And conversely, 00:26:39.210 --> 00:26:41.690 if a kid has a severe allergy to bananas, you 00:26:41.690 --> 00:26:44.349 should be suspicious of latex and use non -latex 00:26:44.349 --> 00:26:54.190 gloves. In conditions like SLE and JIA, the treatment 00:26:54.190 --> 00:26:57.009 can feel worse than the disease to the child. 00:26:57.720 --> 00:27:01.380 The mood swings from steroids, roid rage, plus 00:27:01.380 --> 00:27:03.759 the weight gain, plus the acne. It creates a 00:27:03.759 --> 00:27:06.059 compliance battle. It does. And as a nurse, you 00:27:06.059 --> 00:27:08.059 have to validate that. You cannot just dismiss 00:27:08.059 --> 00:27:11.180 their vanity. To a teenager, appearance is reality. 00:27:11.519 --> 00:27:13.180 I know you hate this medicine, but we need to 00:27:13.180 --> 00:27:15.099 save your kidneys. It's a hard conversation, 00:27:15.500 --> 00:27:17.420 but empathy is the key to compliance. You have 00:27:17.420 --> 00:27:19.819 to be on their team. Connection three, the infection 00:27:19.819 --> 00:27:22.680 loop. This is the biggest safety takeaway. SCID 00:27:22.680 --> 00:27:26.009 patients have no immune system naturally. SLE 00:27:26.009 --> 00:27:28.650 and JIA patients have suppressed immune systems 00:27:28.650 --> 00:27:30.670 artificially because of the meds we give them. 00:27:31.009 --> 00:27:32.769 So the result is the same. They're both vulnerable. 00:27:33.309 --> 00:27:36.849 Exactly. Both groups require a neutropenic precautions 00:27:36.849 --> 00:27:40.210 mindset. Fever is the enemy. Crowds are the enemy. 00:27:40.710 --> 00:27:43.660 And here's the big one. Live vaccines. Tell me 00:27:43.660 --> 00:27:45.680 about live vaccines. Which ones are those? Live 00:27:45.680 --> 00:27:48.880 vaccines like MMR for measles mumps, rubella, 00:27:49.039 --> 00:27:52.019 varicella for chicken pox, rotavirus, and the 00:27:52.019 --> 00:27:54.940 nasal flu spray are generally contraindicated 00:27:54.940 --> 00:27:57.220 because their body can't handle even the weakened 00:27:57.220 --> 00:27:59.700 virus. You could actually give them the disease 00:27:59.700 --> 00:28:01.880 you were trying to prevent. That is a massive 00:28:01.880 --> 00:28:04.920 exam point. No live vaccines for the immunosuppressed 00:28:04.920 --> 00:28:08.130 kids. Massive. Can't miss it. If you see an order 00:28:08.130 --> 00:28:11.690 for MMR on a CID baby or a kid on high -dose 00:28:11.690 --> 00:28:14.490 steroids or methotrexate, you question that order. 00:28:14.890 --> 00:28:17.109 You protect your patient. We have covered a ton 00:28:17.109 --> 00:28:19.309 of ground. We've mapped the landscape, dived 00:28:19.309 --> 00:28:21.670 into the diseases, reviewed the meds, and connected 00:28:21.670 --> 00:28:23.730 the dots. We have. It's a lot of information, 00:28:23.789 --> 00:28:25.930 but remember the patterns. It helps organize 00:28:25.930 --> 00:28:28.049 everything. Before we wrap up, I want to leave 00:28:28.049 --> 00:28:29.740 the listeners with a final thought. Something 00:28:29.740 --> 00:28:31.720 to chew on. I'd like to challenge everyone to 00:28:31.720 --> 00:28:33.660 think about the concept of invisible illness. 00:28:34.140 --> 00:28:36.740 In pediatrics, we're used to looking for the 00:28:36.740 --> 00:28:40.500 obvious. The crying baby. The bleeding wound. 00:28:40.980 --> 00:28:43.680 The high fever. But the conditions we discuss 00:28:43.680 --> 00:28:47.799 today, JIA or early GBS, or even lupus between 00:28:47.799 --> 00:28:50.839 flares, often present quietly. They don't look 00:28:50.839 --> 00:28:53.829 sick at first glance. Right. A child with JIA 00:28:53.829 --> 00:28:55.809 who doesn't want to run at recess might just 00:28:55.809 --> 00:28:58.650 look lazy to a teacher. A baby with GBS who's 00:28:58.650 --> 00:29:01.329 getting floppy might just seem tired or fussy 00:29:01.329 --> 00:29:03.970 to a parent. A teen with lupus fatigue might 00:29:03.970 --> 00:29:06.130 just look like a moody teenager sleeping all 00:29:06.130 --> 00:29:09.289 day. And the nurse's job? Your job is to look 00:29:09.289 --> 00:29:12.220 past the surface, to see the pattern. to notice 00:29:12.220 --> 00:29:14.359 that the laziness is actually stiffness that's 00:29:14.359 --> 00:29:17.259 worse in the morning, to notice that the fussiness 00:29:17.259 --> 00:29:19.680 is actually ascending weakness, to notice that 00:29:19.680 --> 00:29:22.339 the moodiness is pathological fatigue. You have 00:29:22.339 --> 00:29:24.400 to be the detective before the crash happens. 00:29:24.500 --> 00:29:26.339 That gives me chills. It's not just about passing 00:29:26.339 --> 00:29:28.480 the test. It's about being the one who notices. 00:29:28.839 --> 00:29:31.660 Exactly. That is the essence of pediatric nursing. 00:29:32.000 --> 00:29:33.960 You are the voice for the child who can't explain 00:29:33.960 --> 00:29:36.059 why they feel wrong. Thank you. This has been 00:29:36.059 --> 00:29:38.819 an incredible survival guide. My pleasure. To 00:29:38.819 --> 00:29:42.309 our listeners, take these patterns. Absent defense. 00:29:42.630 --> 00:29:45.690 Self -attack. Ascending threat. Immediate collapse. 00:29:45.869 --> 00:29:48.170 Keep them in your pocket. Ace that exam. But 00:29:48.170 --> 00:29:49.970 more importantly, keep those kids safe on the 00:29:49.970 --> 00:29:52.730 floor. You've got this. See you next time. This 00:29:52.730 --> 00:29:55.029 has been The Deep Dive, signing off.
