What’s the best maneuver for reducing a dislocated shoulder? My guess is as good as yours. There are multiple maneuvers that work – and work well for anterior (AKA anterior-inferior) dislocations. This episode reviews how to manage shoulder dislocations in the Pediatric population.

Welcome to PEM Currents, the Pediatric Emergency Medicine Podcast. As always, I’m your host, Brad Sobolewski, and this episode focuses on the management of children with metabolic disorders who present to the emergency department. I know that this is a subject that makes us all a little bit nervous, and you’re just hoping that the parents have a good laminated sheet to tell you everything that you need to do.



Unfortunately, that’s not always the case. And, let’s face it, there are some great principles that you can apply across metabolic diseases to make sure that you are safely taking care of these children. And you’re thinking, hey! Brad’s not a pediatric medical geneticist. No, I’m not. So I called in a ringer.



Or, well, the ringer called me. So my special guest host on this episode is a trainee in pediatrics and medical genetics. Her name is Emily Groopman, and she’s a current resident at Children’s National Hospital. After doing her MD PhD at Columbia University, where she investigated the genetic diagnosis of kidney disease, she started her residency training with the long term goal of being a physician scientist caring ...

Metabolic Disorders


Newborn infants need intramuscular injections of Vitamin K in order to produce critical clotting factors. If they don’t get it they can have potentially life threatening bleeding.

Welcome to PEM Currents, the pediatric emergency medicine podcast. As always, I’m your host, Brad Sobolewski. Today, we’re gonna talk about vitamin k deficient bleeding, also known as hemorrhagic disease of the newborn. This is a bleeding disorder that manifests in the first few days to weeks of life after delivery. Under the umbrella are a whole range of hemorrhagic diseases, but the most important is vitamin k deficient bleeding.



I’ll get into why in a moment. Vitamin k itself is a fat soluble vitamin mainly synthesized by gut bacteria. Newborns have minimal vitamin k reserves in a sterile gut. And there’s insufficient placental transfer and breast milk is deficient in vitamin K, so that’s why infants need vitamin K at birth. Without it, they can’t produce clotting factors 2, 7, 9, and 10.



You need all those. In brand newborns, the levels are about 20 percent or less of adult values, but within a month after birth, they arise to within normal limits. Other causes of hemorrhagic disease of the newborn include hereditary clotting factor deficiencies such as hemophilia A or B. And the most common item on the differential, especially for late onset, which we’ll talk about in a moment, is trauma, non accidental or accidental trauma. So why am I covering this topic?



Well, a lot of people out there are actually refusing vitamin k for their newborns. Why? Well, families state that they have concerns about the preservative in the injection, maybe that it could cause autism. It doesn’t. The pain from the injection could be harmful to the infant.



They perceive that the intramuscular vitamin k is a vaccine. It’s not. The dose of intramuscular vitamin K is too high. It isn’t. A potential for adverse reactions to an injection like anaphylaxis.



Anaphylaxis can happen after IV infusion and it̵...

Vitamin K Deficient Bleeding (Hemorrhagic disease of the newborn)


This episode will help you recognize cellulitis and even differentiate it from erysipelas which is totally a different thing. You’ll also learn about treatment, whether or not a blood culture is necessary, and a whole lot more.

 Welcome to another episode of PEM Currents, the Pediatric Emergency Medicine Podcast. As always, I’m your host, Brad Sobolewski, and today’s episode is all about cellulitis. What is it? Well when a break in the skin occurs, normal skin, flora, and bacteria can enter the subcutaneous tissue, where they do not belong, and they can also invade the lymphatic system.



And although this podcast episode is entitled cellulitis, I’m also going to talk about erysipelas. The two terms are not interchangeable. but both manifest as areas of skin, erythema, edema, and warmth. Cellulitis involves the deeper dermis and subcutaneous fat. Whereas erysipelas involves the upper dermis and there’s a more clear demarcation between the involved and uninvolved tissue.



There’s a fun fact, since the ear doesn’t have deep or dermal tissue, it’s always. ear-a-sipelas. I’ll pause for laughter. Anyway, a skin abscess, which is not the focus of this episode, is a collection of pus deep within the dermis or subcutaneous space. Impetigo, also not included in this episode, is a very superficial infection with that honey crusted drainage. There are also bullous versions. So cellulitis tends to develop in a bit more of an indolent fashion over a few to several days, whereas erys syphilis is more acute. You get systemic symptoms faster, such as fever. Chills, severe malaise, and headache. These can precede the onset of the local skin changes and start just in a matter of hours.



Clinically, for both, you’ll see areas of skin erythema. edema and warmth.

Cellulitis


Laryngomalacia, is the most common cause of infant stridor. Early diagnosis is crucial as it can impact a child’s growth and development. Most infants get better on their own, but those with severe symptoms need surgical interventions like supraglottoplasty. Learn all about diagnosis and management of this common problem in this brief podcast episode.

Welcome to another episode of PEMCurrents, the pediatric emergency medicine podcast. As always, I’m your host, Brad Sobelewski. Your time is valuable and was mine, and that’s why I release these brief episodes, focus on a single topic, get you in, get you out, teach you something. Today, let’s talk about The most common cause of noisy breathing in newborns and infants, laryngomalacia. You’ve all seen this, or should I say you’ve all heard this, And you will hear the symptoms of stridor and noisy breathing, often positional, and it can impact growth and development.



Now I always thought it was just because airways are small and they’re floppier and therefore noisier, but All infants have small airways and all of their cartilage is soft, so there’s more to the picture. So why does this happen? Well, it could be neurologic function. You could have abnormal tone of the laryngeal nerve. You might have an imbalance of demand supply during inhalation in some infants.



And reflux isn’t a direct cause, but approximately sixty percent of infants with laryngomalacia do also have gastroesophageal acid reflux disease. And we know that reflux can irritate and swell the upper airway, potentially worsening obstructive symptoms. So the incidence is unknown, but it’s probably about one in two to three thousand infants. But it might underestimate it because lots of mild cases don’t actually present clinically, and they’re not diagnosed endoscopically. In the past, we thought there was a male predominance, But it’s equally common in female infants, and black and Hispanic infants may have a higher risk compared with white infants.



Low birth weight has also been suggested to be a contributing factor. So when you’re looking at an infant with possible laryngomalacia, You need a very detailed birth history. So were there any surgical procedures or intubations?

Laryngomalacia


Meckel diverticulum is a congenital anomaly of the small intestine that can present with various clinical manifestations, including rectal bleeding and obstruction. Recognizing the characteristic features and understanding the differential diagnosis is crucial in managing patients with lower gastrointestinal bleeding. This episode will help you recognize and diagnose this surgical condition that you probably remember because the “rule of twos.”

Welcome to PEMCurrents: The Pediatric Emergency Medicine Podcast. As always, I’m your host, Brad Sobolewski. Your time is valuable and so is mine. And that’s why I release these brief, succinct episodes focused on a single clinical topic, get you in, get you out, teach you something. Today I’m going to talk about Meckel diverticulum. If you haven’t seen it clinically, you have seen it on a test and it is absolutely something that you should be thinking about when you see a patient with bloody stools in the emergency department.



So Meckel diverticulum is a congenital abnormality of the small intestine and it’s the most common cause of significant lower GI bleeding in children. It arises from an incomplete involution of the vitelline duct during embryonic development. You didn’t think I’d say that during this podcast.



Typically occurring during the seventh week of gestation. It’s characterized by a blind ending true diverticulum, a pouch, that contains all of the layers typically found in the ileum. So especially relevant to board exams, Meckel diverticulum follows the rule of twos. So it affects approximately 2 percent of the population.



It’s located about two feet from the ileocecal valve. It’s usually about two inches long. Only about 2 percent of cases actually become symptomatic. It is most commonly diagnosed by the age of two years, with 45 percent of symptomatic cases occurring in this age group. It is two times as common in boys, and there are two types of epithelium found in the meckle diverticulum, gastric and pancreatic.



So the clinical presentation of Meckel can vary depending on the complications that arise. The most common presentation in children Under the age of five years is rectal bleeding, which may be intermittent or just massive,
