Today we discuss pediatric fractures in the emergency department.  We focus on how to identify fractures that may be indicative of child abuse versus those caused by accidental trauma or other medical conditions.This episode was written by UCD pediatric resident Mariama Lei Poquiz, with content support from pediatric emergency medicine and child abuse specialist Julia Magaña and additional help and guidance from pediatric hospitalist Lidia Park. Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.Follow us on Twitter/X @Pediagogypod, Instagram/Threads @pediagogy, Bluesky @pediagogypodcast.bluesky.social, and connect with us at [email protected] points:·       Pediatric fractures may be the cause of accidental, medical, or non-accidental causes. Evaluation of pediatric fractures caused by non-accidental trauma can be done by taking a thorough history, a meticulous physical exam, and clinical judgement supplemented by imaging and laboratory data.  ·       While there are no pathognomonic fractures indicative of child abuse, there are high risk features that increase the suspicion for child abuse. Additionally, there are fractures with higher specificity for child abuse than others. These high specificity fractures include those in the ribs, pelvis, scapula, sternum, classic metaphyseal lesions, and long bones in non-ambulatory children.  ·       Toddler’s fractures are accidental fractures that may mimic child abuse.  ·       The radiographic skeletal survey is the standard screening tool for evaluating children under 2 years old who are suspected of being abused. It is important to also do a follow up skeletal survey approximately 2 weeks after the initial one if the first skeletal survey was positive, equivocal, or negative, but with persistent clinical suspicion. These specific findings can be found in the American College of Radiology guidelines. Other work-up can include head imaging and laboratory studies.    Sources:   Auerbach, M., Coombs, C., Lindberg, D., Magaña, J., Ornstein, A., Sharma, S., & Tiyyagura, G.

When do we use inflammatory markers? What do they tell us? Learn how these lab values make a difference in your clinical decision making!This episode was written by pediatricians Lidia Park and Tammy Yau as well as pediatrics resident Anjali Doshi, with content support from Natasha Nakra, pediatric infectious disease physician.

It is non-specific and doesn’t always indicate infection. CRP is an acute phase reactant that can be useful in inflammation or infection, but is also non-specific. This can be useful in trending if an infectious process or inflammation is improving.Recent studies now show that procalcitonin is a non-specific marker for bacterial infections and more clinicians are leaning away from using this marker.It is important before ordering these markers to assess which is needed and if a normal or elevated level will change your clinical plan before ordering unnecessary tests.References:Pihl AF, Balamuth F, Michelson KA.

The threshold needed to prevent large scale measles outbreaks is 95%. Only 92.7% of kindergarteners in the US received both MMR shots for the 2023-2024.Symptoms of measles includes cough, conjunctivitis, coryza (rhinorrhea), Koplik spots (white spots in the mouth), and rash spreading from the face down, Serious complications include death (1-3 deaths per 1000 cases), encephalitis (20% mortality), and subacute sclerosing panencephalitis (SSPE) which is almost universally fatal.Sources:“What’s Old is New Again: Measles”. Pediatrics (2025) 155 (6): e2025071332. https://doi.org/10.1542/peds.2025-071332“CDC Confirms Worst Year for Measles since 1992”. AAP News. Sean Stangland. Jul 9 2025.“Vaccines Matter: Measles and Its Complications”. Pediatrics (2025) 156 (1): e2025071622. https://doi.org/10.1542/peds.2025-071622Mina MJ, Metcalf CJE, de Swart RL, Osterhaus ADME, Grenfell BT.

Opioid use disorders affect babies and children in all ways. In newborns, it can present as neonatal opioid withdrawal syndrome (also known as NOWS). Learn how hospital systems are managing infants with NOWS with the Eat, Sleep, Console protocol in our episdoe today!Key Points:Eat Sleep Console (ESC) focuses on non-pharmacological intervention first before initiating medication. This includes limiting excessive stimulation, keeping the room dark and quiet, swaddling, rocking, swaying, and giving babies a pacifier or feeding.Compared to using the Finnegan scoring system, ESC results in shorter or equal length of hospital stay for infants with NOWS. However, some critics of ESC raise the concern for undertreating infants with NOWS.Morphine, clonidine, and phenobarbital are common agents used to treat infant with NOWSSources:Neoreviews (2025) 26 (4): e223–e232. https://doi.org/10.1542/neo.26-4-010Hosp Pediatr (2025) 15 (3): e121–e125. https://doi.org/10.1542/hpeds.2024-008094Hosp Pediatr (2025) 15 (3): e99–e101. https://doi.org/10.1542/hpeds.2025-008332Kaltenbach K, O'Grady KE, Heil SH, et al.

Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation. Key Points:Vaccine benefits largely outweigh risks.Vaccines do not cause autism. The frequently cited study that reportedly links vaccines to autism was funded by an anti-vaccine group and only looked at 12 children.Thimerisol is a preservative that is not used in routine vaccinations other than certain influenza vaccines. Anti vaccine groups raise the concern for ethylmercury toxicity from thimerisol but studies looking at mercury levels after vaccination with thimerisol containing vaccines showed the peak mercury levels to still be within the normal EPA range.Oral rotavirus is associated with an increased risk of intussusception. A history of intussusception is a contraindication to the rotavirus vaccineSources:Pediatrics (2016) 138 (3): e20162146. https://doi.org/10.1542/peds.2016-2146Pediatrics (2024) 153 (3): e2023065483. https://doi.org/10.1542/peds.2023-065483Desai R, Cortese MM, Meltzer MI, et al.

With increasing awareness and diagnosis of autism, there has also been an increase in misinformation regarding autism. The goal of today's episode is to provide a brief overview on autism and provide evidenced based information to better inform listeners!Follow us on Twitter/X @Pediagogypod, Instagram/Threads @pediagogy, Bluesky @pediagogypodcast.bluesky.social, and connect with us at [email protected] episode was written by pediatricians Tammy Yau and Lidia Park with content support from Kathleen Angkustsiri (UC Davis developmental and behavioral pediatric specialist). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation. Key Points:Autism diagnostic criteria have changed to increase detection of milder cases. Asperger's is included in autism. Per the DSM-5, autism is a condition with impairments in social communication (social and emotional reciprocity, non-verbal communication, and relationships) and restrictive and repetitive behaviors.  Autism diagnosis also requires 2 out of 4 restrictive or repetitive behaviors: 1. Restrictive or repetitive patterns of behavior, interests, or activities 2. Insistence of sameness, inflexible adherence to routines, ritualized patterns 3. Highly restricted, fixated interest abnormal in intensity or focus. 4. Hyper or hyporeactivity to sensory input or unusual interest in sensory aspects of the environmentAutism can present as regression of social and/or language skills.The Modified Checklist for Autism in Toddlers – Revised with Follow-up (MCHAT-R/F) is the most widely known and validated screening tool for autism for ages 16-30 months. A score of 8 or more is high risk for autismSources:Pediatrics (2020) 145 (1): e20193447. https://doi.org/10.1542/peds.2019-3447

Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation. Key points:Genetic testing may seem relatively benign and non-invasive but is actually fraught with unforeseen issues such as surprise consanguinity and non-paternity.Racial and economic disparities are prevalent with genetic testing and their interpretation. For example most test value interpretations are based on people of European and Asian descent.We cannot easily predict outcomes and prognosticate even with genetic testing. Prognosis is often fraught with the issue of promoting "ableism".Sources:Katharine P. Callahan, Ellen W. Clayton, Amy A. Lemke, Bimal P. Chaudhari, Tara L. Wenger, Allison N. J. Lyle, Kyle B.

Marijuana, cannabis, THC, and CBD are among the many common words and forms of cannabis that pediatric patients are being exposed to in our current day and age. Keep up to date about the official AAP policy and recommendations with today's episode. Follow us on Twitter/X @Pediagogypod, Instagram/Threads @pediagogy, Bluesky @pediagogypodcast.bluesky.social, and connect with us at [email protected] This episode was written by pediatricians Tammy Yau and Lidia Park. Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.  Key Points: At the time of this episode release, marijuana is considered a schedule I drug at the federal level meaning here is high potential for abuse, no medical use, and/or lack of safety with using this drug. The official AAP stance is to avoid cannabinoid use in most children. More studies need to be done to determine the long term effects. Cannabis plants generally have both THC and CBD which are types of cannabinoids. THC can cause intoxication, analgesia, and antiemesis. CBD is less intoxicating and anxiolytic.  Cannabis intoxication can cause tachycardia, hypertension, red eyes, dry mouth, orthostatic hypotension, increased appetite and thirst, drowsiness, insomnia, anxiety, short term memory loss, ataxia, stroke, nystagmus, hypothermia, hypotonia, and rarely respiratory depression. Treatment is supportive. THC can be detected in breastmilk. There is not enough information about long term safety and implications of THC exposure in utero or while breastfeeding.  In children, epidiolex is the only plant derived cannabinoid FDA approved for use of severe seizures in children. Sources: Ammerman S, et al.

Have you ever wondered if your patient's snoring is concerning or not? Learn about how we screen for obstructive sleep apnea in pediatric patients in this episode.Follow us on Twitter/X @Pediagogypod, Instagram/Threads @pediagogy, Bluesky @pediagogypodcast.bsky.social, and connect with us at [email protected] episode was written by pediatricians Lidia Park, Tammy Yau, and Jessica Ahn with content support from Ambika Chidambaram (UCD pediatric pulmonology). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.   Key PointsObstructive sleep apnea (OSA) occurs when there is either complete or partial narrowing of the upper airway during sleep that causes an awakening from sleep and/or results in at least 3% drop in oxygen saturation and lasts 2 breath lengths.Symptoms of OSA can include episodes of apnea, gasping, choking, frequent awakenings, sleep enuresis, attention difficulties, behavioral problems, daytime sleepiness.On physical exam, watch out for enlarged tonsils and/or adenoids, micrognathia, retrognathia, or hypotonia.Untreated OSA is an independent comorbid factor for many conditions such as failure to thrive, obesity, and cardiovascular diseases like insulin resistance, fatty liver disease, and hypertension.Disorders associated with OSA include Down syndrome, Duchenne Muscular Dystrophy, Prader Willi, achondroplasia, hypothyroidism, and acromegaly.The gold standard for diagnosis of OSA is polysomnography and is based off of AHI scores: 1-5 is mild, 6-10 is moderate, and 11 or greater is severe.First line treatment for most children is adenotonsillectomy. If this fails, second line treatment is CPAP or BiPAP. ReferencesKrishna J, Kalra M, McQuillan ME. Sleep disorders in childhood.

Unequal blood pressures in the extremities and unequal brachial vs femoral pulses? Consider coarctation of the aorta. What’s that? Learn more in today's episode!  This episode was written by pediatricians Lidia Park and Tammy Yau with content support from Jay Yeh (UC Davis pediatric cardiologist). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.   Key Points: Coarctation of the aorta is narrowing of the aorta near the ductus arteriosus (which closes and becomes the ligamentum arteriosum). Most cases occur in the first month of life.  Symptoms of coarctation of the aorta are tachypnea, poor feeding, fussiness, and sweating with feeds. Blood pressure is elevated in the right upper extremity compared to the lower extremity. Babies can develop congestive heart failure which can lead to shock.  CCHD does not always catch coarctations of the aorta!  Sources: Raza S, Aggarwal S, Jenkins P, et al.

Don’t miss this “ear”-resistible episode on outer ear infections, also known as otitis externa or swimmer’s ear!This episode was written by Dr. Tammy Yau and Dr. Lidia Park with content support from Dr. Lena van Der List. Drs. Tammy and Lidia take full responsibility for any errors or misinformation. Key Points:Think otitis externa when your patient has ear pain, ear drainage, decreased hearing, and swelling or debris in the ear canal. Treat otitis externa with otic aminoglycosides (neomycin, polymyxin B, trimethoprim-sulfate) when you have an intact tympanic membrane or fluoroquinolone (ciprofloxacin, ofloxacin) if you can’t visualize the tympanic membrane or there is a perforationSources:Pediatrics in Review 2013, https://doi.org/10.1542/pir.34-3-143

Get a real ear-full of information today when we talk about the 2nd most common diagnosis in the pediatric emergency department, acute otitis media (AOM)!This episode was written by Dr. Tammy Yau and Dr. Lidia Park with content support from Dr. Lena Van der list. Drs. Tammy and Lidia take full responsibility for any errors or misinformation. Key Points:Ear pain with a red bulging tympanic membrane and decreased tympanic membrane mobility is our diagnosis for acute otitis media. AOM can be due to bacteria (S. pneumoniae, H. influenza, and Moraxella) and viruses (influenza, adenovirus, human metapneumovirus)Treat AOM with high dose amoxicillin (cephalexin or azithromycin if penicillin allergy) or amoxicillin-clavulanate. Avoid complications like mastoiditis or tympanic membrane perforationSources:Pediatrics 2013, https://doi.org/10.1542/peds.2012-3488Stat Pearls 2023, https://www.ncbi.nlm.nih.gov/books/NBK470332/ World Journal of Pediatrics 2024, https://doi.org/10.1007/s12519-023-00716-8 University of Illinois Chicago: https://dig.pharmacy.uic.edu/faqs/2022-2/december-2022-faqs/what-evidence-supports-the-recommendation-for-high-dose-amoxicillin-in-children-with-acute-otitis-media/

Drs. Lidia and Tammy take full responsibility for any errors or misinformation.  Key Points: Perinatal hepatitis C exposure is the most common cause of pediatric hepatitis C infection NAT testing for hepatitis C RNA can be done as early as 2 months of life to detect hepatitis C infection in pediatric patients rather than waiting until 18 months of life when hepatitis C antibody testing can be done Hepatitis C positive moms can still breastfeed but should halt breastfeeding temporarily if breasts are cracked or bleeding Sources: CDC: CDC Recommendations for Hepatitis C Testing Among Perinatally Exposed Infants and Children — United States, 2023 | MMWR AAP Red Book 2024: Hepatitis C  

Ever wonder what CCHD meant on a newborn discharge summary? Learn about how we screen for Critical Congenital Heart Defects in newborns (and which ones we miss!) in this episode. This episode was written by Dr. Lidia Park and Dr. Tammy Yau with content support from Dr. Heather Siefkes. Drs. Lidia and Tammy take full responsibility for any errors or misinformation.  Key Points: Critical Congenital Heart Defects (CCHD) screening looks for heart defects that can be life threatening in infancy such as coarctation of the aorta, single ventricle defects like hypoplastic left heart syndrome, Tetralogy of Fallot (ToF), pulmonary atresia, total anomalous pulmonary venous return (TAPVR), transposition of the great arteries (TGA), and tricuspid atresia (TA). CCHD screening does not detect atrial septal defects (ASD), ventricular septal defects (VSD), or atrioventricular septal defects (AVSD) CCHD screening is performed by checking the pulse oximeter of the right hand and either foot of a newborn. SpO2 less than 90% is an automatic fail. SpO2 differences of 3% or more or SpO2 91-95% should be repeated twice before counting as a fail. Failed CCHD’s should be followed up with an echocardiogram. Sources: CDC: Clinical Screening and Diagnosis for Critical Congenital Heart Defects | Congenital Heart Defects (CHDs) | CDC BMC Pediatric 2021, Jullien S.

Did you know that if you exercise while you have a fever, you probably meet SIRS criteria? The new Phoenix sepsis scoring systems aims to better categorize sepsis through specific categories based on the patient’s vitals, labs, and medications. Learn with us as we walk through this new scoring system in today’s episode. This episode was written by Dr. Lidia Park and Dr. Tammy Yau with content support from Dr. Alexis Toney. Drs. Lidia and Tammy take full responsibility for any errors or misinformation. Key Points:  The Phoenix sepsis score is based out of 13 points. 2 or more points meets sepsis criteria. The score is based on 4 categories: respiratory, cardiovascular, coagulation, and neurologic. The Phoenix sepsis score is better at predicting mortality than SIRS criteria but does not predict morbidity Sources: JAMA 2024, Schlapbach,“International Consensus Criteria for Pediatric Sepsis and Septic Shock”: doi: 10.1001/jama.2024.0179. Hospital Pediatrics 2023, Kusma, “Effect of Viral Illness on Procalcitonin as a Predictor of Bacterial Infection in Febrile Infants”: doi: 10.1542/hpeds.2022-007070
