Paediatrics: Precocious Puberty: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Precocious Puberty: Paediatric Endocrinology Essentials🎧 Fast, focused audio revision for MSRA, GP trainees, paediatrics exams, and anyone prepping for paediatric endocrine cases.🧠 Key Learning Points📌 Definition• Precocious puberty = onset of secondary sexual characteristics before age 8 in girls, before age 9 in boys• Two main types: – Central (gonadotrophin-dependent): Premature activation of the HPG (hypothalamic-pituitary-gonadal) axis; high LH/FSH – Peripheral (gonadotrophin-independent): Hormone production from outside the brain’s control; low LH/FSH📌 Causes & Risk Factors• Central (most common, esp. girls): – Usually idiopathic (no identifiable cause) – Can be due to CNS tumours, trauma, congenital brain abnormalities• Peripheral: – Congenital adrenal hyperplasia, hormone-secreting tumours (adrenal, ovarian/testicular), McCune-Albright syndrome, exogenous hormones• Risk factors: – Female sex (10:1 ratio), family history, some ethnicities (e.g. African descent), possibly obesity📌 Pathophysiology• Central: Early signal from brain → increased LH/FSH → ↑ oestrogen/testosterone → early sexual development• Peripheral: Hormones produced independently of the pituitary📌 Clinical Features• Girls: Early breast development (thelarche), pubic/axillary hair, rapid growth, emotional changes• Boys: Testicular enlargement, pubic/axillary hair, rapid growth, body odour, acne• Both: Advanced bone age on x-ray, possible behaviour changes📌 Differential Diagnosis• Normal variant (early but normal puberty)• Benign variants: Isolated premature thelarche, adrenarche, or menarche• Hypothyroidism (can mimic or alter puberty)• Tumours (CNS, gonadal, adrenal), congenital adrenal hyperplasia, genetic syndromes (e.g. McCune-Albright)📌 Assessment & Investigations• History: Timing, progression, family history, neuro symptoms• Exam: Height, weight, Tanner staging, neuro exam• Labs: LH, FSH, oestradiol/testosterone, TFTs, adrenal androgens• Imaging: Bone age x-ray (wrist/hand), MRI brain (to exclude CNS cause), pelvic/testicular/adrenal US if indicated• Stimulation tests: GnRH stimulation (central vs peripheral)📌 Management• Central: GnRH analogues (monthly injections) to pause progression• Peripheral: Treat the underlying cause (e.g. surgery for tumours, steroids for CAH, aromatase inhibitors for rare conditions)• Support: Psychological support for child/family• Multidisciplinary approach—tailored to individual & underlying aetiology📌 Prognosis & Complications• If untreated: Early bone maturation → short adult stature, psychological distress, possible behaviour/mental health impact• With treatment: Can often achieve normal adult height and minimise psychosocial difficulties• Prognosis depends on cause—idiopathic central has best outlook📚 Full Precocious Puberty MSRA Resources:📝 Revision Notes: https://www.passthemsra.com/topic/precocious-puberty-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/precocious-puberty-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/precocious-puberty-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/precocious-puberty-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #PrecociousPuberty #Paediatrics #MSRARevision #GPRevision #PaedsEndocrinology #Puberty #MSRAFlashcards #MSRAQuiz #NICEGuidelines #PaedsEndo
