  • The Limping Child

    The Limping Child
    Sep 4 2025
    Limping is a common complaint in pediatric emergency care, but the differential is broad and the stakes are high. In this episode, we walk through a detailed, age-based approach to the evaluation of the limping child. You’ll learn how to integrate the Kocher criteria, when imaging and labs are truly necessary, and how to avoid being misled by small joint effusions on ultrasound. We also highlight critical mimics like appendicitis, testicular torsion, and malignancy—and remind you why watching a child walk is one of the most valuable parts of the exam. Whether it’s transient synovitis, septic arthritis, or something much more concerning, this episode gives you the tools to manage pediatric limps with confidence. Learning Objectives Apply an age-based approach to the differential diagnosis of limping in children.Demonstrate diagnostic reasoning by integrating history, physical exam, imaging, and lab findings to prioritize urgent conditions like septic arthritis and SCFE.Appropriately select and interpret imaging and lab studies, including understanding the utility and limitations of ultrasound, MRI, and the Kocher criteria.

Transcript Note: This transcript was partially completed with the use of the Descript AI and the Chat GPT 5 AI Welcome to PEM Currents, the Pediatric Emergency Medicine podcast. As always, I’m your host, Brad Sobolewski, and in this episode we’re gonna tackle the evaluation of a child presenting with limp. We’ll cover, age-based differential diagnosis. How to take a high yield history and do a detailed physical exam, imaging strategies, lab tests, and when to worry about systemic causes. We’ll also talk about the Kocher criteria for septic arthritis and how to use and not misuse ultrasound when you’re worried about a hip effusion. After listening to this episode, I hope you will all be able to apply an age based. Approach to the differential diagnosis of limp in children. Demonstrate diagnostic reasoning by integrating history, physical exam, imaging, and lab findings to prioritize urgent conditions like septic, arthritis, and scfe, and appropriately select and interpret imaging and lab studies, including understanding the utility and limitations of ultrasound MRI and the Kocher criteria. So let me start out by saying that a limp isn’t a diagnosis, it’s a symptom. It can result from pain, weakness, neurologic issues, or mechanical disruption. So think of limping as the pediatric equivalent of chest pain. In adults. It’s common, it’s broad, and it’s sometimes could be serious. And the key to a good workup is a thought. Age-based approached and kids under three think trauma and congenital conditions between three and 10 transient synovitis range Supreme and over 10 think SCFE and systemic disease. And your differential diagnosis always starts with history. So you gotta ask the family, when did the lymph start? Was it sudden or gradual? Is there a preceding viral illness or an injury? Is the limp worse in the morning? Does it get better with activity? Do the kid complain of pain or are they just favoring one leg? And then are there any systemic symptoms such as fever, rash, weight loss, fatigue, or joint swelling elsewhere? And you wanna find out whether or not the kid is actually bearing any weight at all. Have they had recent travel or known tick exposure? Are they potty trained and are they having accidents now? Have they had any prior episodes of joint swelling or limping like this in the past? And don’t forget a developmental history, especially in kids under preschool age. Most children begin to stand at nine to 12 months. Cruise at 10 to 12 months and walk independently by 12 to 15 months. A child who has never walked normally may have a neuromuscular or congenital problem. When you are evaluating limp, obviously you wanna watch the kid walk, get them outta the exam room if needed. First of all, your exam room is small. Kid may feel confined and they might be more willing to take some steps. If you have ’em out in the hallway, obviously have the caregiver nearby and a toy, a phone, some object of enticement. You wanna watch their stance phase, or they just avoiding bearing weight on one limb. When they’re standing the swing ...

  • Managing Pain in Sickle Cell Vaso-Occlusive Crises

    Managing Pain in Sickle Cell Vaso-Occlusive Crises
    Jul 28 2025
    Vaso-occlusive pain episodes are the most common reason children and adolescents with sickle cell disease present to the Emergency Department. Prompt, protocol-driven management is essential starting with early administration of IV opioids, reassessment at 15–30 minute intervals, and judicious hydration. Understanding the patient’s typical pain pattern, opioid history, and psychosocial context can guide more effective care. This episode walks through the pathophysiology, clinical presentation, pharmacologic strategy, discharge criteria, and complications to watch for helping you provide evidence-based, compassionate care that improves outcomes. Learning Objectives Describe the pathophysiology of vaso-occlusive crises in children and adolescents with sickle cell disease and how it relates to clinical symptoms.Differentiate uncomplicated vaso-occlusive crises from other acute complications of sickle cell disease such as acute chest syndrome, splenic sequestration, and stroke.Implement evidence-based strategies for early and effective pain management in vaso-occlusive crises, including appropriate use of opioid analgesia, reassessment intervals, and disposition criteria.

I’m your host, Brad Sobolewski. In this episode, we’re digging into a common but complex emergency department challenge: pain management for vaso-occlusive crises in children and adolescents with sickle cell disease. These episodes are painful—literally and figuratively. But with thoughtful, evidence-based care, we can make a big difference for our patients. Overview and Epidemiology Vaso-occlusive crises, or VOCs, are the most frequent cause of emergency visits and hospitalizations for individuals with sickle cell disease (SCD). They are responsible for more than 70 percent of ED visits among children with SCD and account for substantial healthcare utilization and missed school days. Most children with homozygous HbSS will experience their first painful episode before the age of 6. Recurrent VOCs are associated with higher risks of chronic pain, opioid use, and diminished quality of life. Why Do VOCs Happen? Sickle cell disease is caused by a point mutation in the beta-globin gene, leading to hemoglobin S. Under stress—such as infection, dehydration, or even cold exposure—red blood cells polymerize, sickle, and become rigid. These sickled cells obstruct capillaries and small vessels, leading to local tissue ischemia, inflammation, and pain. It’s not just about the blockage—the inflammatory cascade, endothelial damage, and cytokine release all contribute to the pain experience. What Does the Pain Feel Like? Ask kids and teens with sickle cell disease, and they’ll describe their pain as deep, throbbing, stabbing, or aching. It often feels bone-deep and can be relentless and exhausting. Many say it’s unlike any other pain—they may compare it to being “hit with a bat,” “bone being crushed,” or “...

  • Penetrating Neck Injuries

    Penetrating Neck Injuries
    Jun 25 2025
    Penetrating neck injuries in children are rare—but when they happen, the stakes are high. In this episode of PEM Currents: The Pediatric Emergency Medicine Podcast, we explore the clinical pearls behind “no-zone” management, how to distinguish hard and soft signs, when to image versus operate, and why airway always comes first. Get ready for a focused, evidence-based deep dive into pediatric neck trauma. Learning Objectives Understand the shift from zone-based to “no-zone” management in pediatric penetrating neck injuries and describe the rationale behind this transition.Apply ATLS principles to the initial assessment and stabilization of children with penetrating neck injuries, including decisions regarding imaging and airway management.Evaluate clinical findings to determine the need for operative intervention versus observation in stable pediatric patients with soft versus hard signs of vascular or aerodigestive injury.

As always, I’m your host, Brad Sobolewski, and in this episode we are diving into a high-stakes but fortunately rare topic in pediatric trauma — penetrating neck injuries. Now these injuries make up less than 1% of all pediatric trauma, but when they occur, they demand precision and vigilance in terms of diagnosis and management. As you know, the neck packs some vital organs, vessels, the airway, esophagus, and nerves into a tiny little area, so even a seemingly minor wound can injure multiple structures. Now you remember — way back when — where you learned about the zones of the neck, and this is the traditional teaching, which chopped the neck up into three zones. You’ve got Zone I, which is the area between the clavicle and cricoid. You’ve got the subclavian arteries and vein, the carotid, and the apices of the lungs. Zone II, the cricoid to the angle of the mandible — this includes the carotids, jugulars, the vagus nerve, the trachea, and the esophagus. And then you have Zone III, which is the angle of the mandible to the base of the skull — you’ve got the distal carotid, the vertebral artery, and cranial nerves IX through XII. Now, you may recall some teaching that you got in medical school or residency where the management was dictated by which zone was injured. And admittedly, a lot of this evidence is in adults, and more penetrating trauma is seen in adults as well. But now practice is leaning towards the “no zone” approach, where imaginary lines on the skin surface are not dictating management as much as presentation, symptoms, and deciding when to go to the OR versus using CT angiography. So let’s talk about mechanisms of injury for a minute. Toddlers can injure their neck when they fall with something in their mouth, like pencils or chopsticks. School-age kids may take a bike handlebar to the neck, or they’re trying to run or jump over a fence and they get impaled on that — that sounds painful. Adolescents, unfortunately, are subject to assaults, stabbings, and gunshot wounds, as well as clothesline-type injuries or other high-velocity injury where the neck is injured as they’re riding a bike. So low-velocity mechanisms dominate pediatric penetrating neck injuries. Force matters, because depth and tissue cavitation decide the overall injury pattern. In terms of assessing the patient with a penetrating neck injury, it all starts with the ABCs. Is the patient’s airway patent? Are they protecting and maintaining it? Look for signs such as hoarseness, stridor, aphonia (they can’t talk at all), a bubbling wound, or an expanding hematoma. For breathing, patients should be breathing comfortably with no distress. Look for any signs of asymmetry on chest rise, feeling of crepitus or subcutaneous air, or diminished breath sounds — obviously the latter two indicating a pneumothorax or even hemothorax. For circulation, if the wound is bleeding, apply direct pressure. Some surgeons will use a Foley balloon tamponade method if they need to stop bleeding before going to the operating room. Patients will need large bore IVs and fluids — and especially blood product resuscitation. Only immobilize the C-spine if a patient has neurologic deficits or a high injury mechanism. Think — somebody that was ...
