Paediatrics: Hypothyroidism: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Hypothyroidism in Children🎧 A clear, high-yield breakdown of this common but crucial endocrine condition – perfect for exam prep and real-life paediatrics.🧠 Key Learning Points📌 Definition• Paediatric hypothyroidism = underactive thyroid in children, leading to reduced T3/T4 → growth + developmental delays.📌 Causes & Risk Factors• Congenital Hypothyroidism (CH) – most common• Hashimoto’s thyroiditis (autoimmune)• Iodine deficiency• Pituitary or hypothalamic dysfunction• Transient maternal antibody/medication effects• Genetic syndromes (e.g. Down, Turner)🧠 Mnemonic: "HIP TAG"Hashimoto’sIodine deficiencyPituitary defectsTransient causesAgenesic glandGenetic syndromes📌 Pathophysiology• ↓ T3/T4 → impaired metabolism• Disruption in growth, neurodevelopment, and puberty• Severity depends on timing (congenital vs acquired)📌 Symptoms• Fatigue, weight gain, constipation• Poor growth, delayed puberty• Dry skin, cold intolerance• Infant: prolonged jaundice, hypotonia, somnolence, large fontanelles🧠 Mnemonic (Infant): "JUMP COLD"JaundiceUmbilical herniaMacroglossiaPoor feedingCry (weak)Overly sleepyLarge fontanellesDevelopmental delay📌 Differential Diagnosis• Growth hormone deficiency• Chronic illness/malnutrition• Delayed puberty• Medication interference• Congenital syndromes📌 Diagnosis• Newborn screening: Heel prick (TSH, T4)• TFTs: ↑ TSH, ↓ free T4• Thyroid autoantibodies (Hashimoto’s)• Ultrasound for thyroid anatomy• Radionuclide scan for gland function• Genetic testing if indicated🧠 Tip: Low T4 + high TSH = primary hypothyroidism📌 Management✅ Levothyroxine (L-thyroxine) lifelong• Start early to prevent neurodevelopmental damage• Dose adjusted to maintain free T4 in upper half of age range✅ Monitoring• Regular TFTs• Growth charts + developmental milestones⚠️ Watch for over/under treatment → hyper/hypo symptoms• Transient cases: treat if TSH remains high after 2 weeks; review at 3–5 months📌 Complications• Irreversible intellectual disability• Short stature, delayed puberty• Goitre, bradycardia, pericardial effusion• Psychosocial issues: low self-esteem, depression📌 Prognosis• 🌟 Excellent with early diagnosis + adherence to treatment• Delayed treatment = risk of cognitive disability, gait issues, speech delay📎 More MSRA Resources for Hypothyroidism in Children📝 Revision Notes:https://www.passthemsra.com/topic/hypothyroidism-in-children-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/hypothyroidism-in-children-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/hypothyroidism-in-children-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/hypothyroidism-in-children-rapid-quiz/🎓 Full Course:https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRAHypothyroidism #MSRAFlashcards #MSRAQandANotes #MSRAQuiz #Paediatrics #HypothyroidismInChildren #PassTheMSRA #MSRAAccordions #MSRAOnlineRevision #MultiSpecialtyRecruitmentAssessment
