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".

This episode was written by pediatric resident Victoria Tran Toft and pediatricians Tammy Yau and Lidia Park with content support from Natasha Nakra (UC Davis pediatric infectious disease). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.

Key points:

• Osteomyelitis can present as limp or hesitancy with movement; this can occur with or without fevers and localizing signs.
• Main diagnostics include CRP, which also aids in assessing treatment response.
• Treatment is a long course of antibiotics. Typically, starting empiric IV antibiotics in the hospital and then transitioning to oral agents.

Key Points:

• Typical diaper rash is an irritant contact dermatitis due to excess moisture, pH imbalance, and excessive friction. It can be a red patch or red macules and papules in the diaper region that spares the skin folds
• Candidal diaper rashes involve the skin folds and have satellite lesions
• Don’t forget in your differential: perianal strep, hand foot mouth syndrome, psoriasis, eczema, scabies, and Langerhans cell histiocytosis

This episode was written by pediatricians Tammy Yau and Lidia Park with content support from Dean Blumberg (UC Davis pediatric infectious disease). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.

Key Points:

• Peritonsillar abscess (PTA) is a suppurative infection of the tissue between the palatine tonsil capsule and the pharyngeal muscles
• Symptoms include fever, sore throat, uvular deviation, trismus, voice changes, drooling, unilateral tonsillar swelling with deviation of the uvula to the contralateral side
• Diagnosis can be clinical but imaging is often obtained
• Treat with antibiotics (empiric amoxicillin, cephalosporin, or clindamycin but adjust based on cultures) and incision and drainage

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.

Don't miss this cause of anemia in your differential in today’s episode about autoimmune hemolytic anemia!

Follow us on Twitter/X @Pediagogypod, Instagram/Threads @pediagogy, Bluesky @pediagogypodcast.bsky.social, and connect with us at pediagogypod@gmail.com

This episode was written by pediatricians Tammy Yau and Lidia Park with content support from Anjali Pawar (UC Davis pediatric hematology). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.

Key Points:

• Autoimmune hemolytic anemia is an extravascular hemolysis
• Symptoms can include pallor, fatigue, lightheadedness, jaundice, tachycardia, acrocyanosis, dark urine, splenomegaly, and gallstones with labs showing anemia with schistocytes, reticulocytosis, hyperbilirubinemia, elevated LDH, elevated AST, and positive Coombs testing.
• AIHA can be triggered by infections, underlying autoimmune diseases, malignancy, immunosuppression, and medications.
• Treatment is steroids or rituximab for warm AIHA and avoiding the cold for cold AIHA. In refractory cases, splenectomy or stem cell transplant may be needed. Transfusions are generally not recommended due to ongoing hemolysis unless anemia is severe.

This episode was written by pediatricians Tammy Yau and Lidia Park with content support from Dean Blumberg (UC Davis pediatric infectious disease). Pediatricians Tammy and Lidia take full responsibility for any errors or misinformation.

Key Points:

• The influenza vaccine is important every flu season!
• Anti-viral neuraminidase inhibitors like oseltamivir/Tamiflu (oral), zanamavir (inhaled), and peramavir (IV) prevent the flu virus from fusing with infected cell membranes preventing the release of the virus
• Baloxivir is a endonuclease inhibitor that inhibits mRNA synthesis that can be given as a one time dose to treat influenza infections.
• Otitis media, PNA, retropharyngeal abscesses, Pott puffy tumors, empyema, meningitis, encephalitis, GBS, acute cerebella ataxia, transverse myelitis, myositis, pericarditis, and myocarditis are all serious complications that can occur with influenza infections
