🧬 MEN Syndromes — Distinguish Them in 60 Seconds ⸻ 1️⃣ MEN 1 — Wermer Syndrome The “3 Ps” 🔸 Pituitary Tumour → e.g., Prolactinoma 🔸 Parathyroid Hyperplasia → most common initial presentation → hypercalcaemia 🔸 Pancreatic Islet Cell Tumours → Gastrinoma (Zollinger–Ellison) + Insulinoma 🧬 Gene: MEN1 (Chromosome 11) → Tumour suppressor mutation ⸻ 2️⃣ MEN 2A — Sipple Syndrome The “2 Ps + 1 M” 🔸 Parathyroid Hyperplasia → hypercalcaemia 🔸 Phaeochromocytoma → adrenal gland tumour 🔸 Medullary Thyroid Carcinoma (MTC) 🧬 Gene: RET proto-oncogene (Chromosome 10) → Activating mutation ⸻ 3️⃣ MEN 2B — Mucosal & Marfanoid The “1 P + 2 Ms” 🔸 Phaeochromocytoma 🔸 Medullary Thyroid Carcinoma → most aggressive form, early onset 🔸 Mucosal Neuromas + Marfanoid Habitus ⚠️ NO parathyroid disease — key distinguishing feature! 🧬 Gene: RET proto-oncogene (Chromosome 10) → Activating mutation ⸻ 4️⃣ The Master Comparison ➊ MEN 1 → Pituitary + Parathyroid + Pancreas (MEN1 gene, Chr 11) ➋ MEN 2A → MTC + Pheo + Parathyroid (RET gene, Chr 10) ➌ MEN 2B → MTC + Pheo + Neuromas/Marfanoid — NO parathyroid (RET gene, Chr 10) ⸻ 🧩 Exam Pearls 🔹 MEN 2B is the MOST aggressive — presents earliest with MTC 🔹 Phaeochromocytoma rule → ALWAYS give alpha-blocker BEFORE beta-blocker to prevent hypertensive crisis 🔹 MEN 1 vs MEN 2 genetics → Tumour suppressor (MEN1) vs Activating oncogene (RET) 🔹 Hypercalcaemia in MEN → think Parathyroid (MEN 1 and 2A only — NOT 2B) ⸻ 📚 Master MEN syndromes and all of endocrinology in our high-yield endocrinology book: 🔗 mediconotes.com ⸻ #MENSyndrome #usmle #Endocrinology #MedicalEducation #doctor

🌀 7 CAUSES OF VERTIGO Vertigo is a symptom, not a diagnosis. When a patient complains of “dizziness,” the key question is: ❓ Is this true vertigo (a false sensation of movement) or something else? Correctly distinguishing peripheral from central causes is essential, as some causes are benign, while others may represent a neurological emergency. 🔑 Common Causes of Vertigo 1️⃣ BPPV (Benign Paroxysmal Positional Vertigo) • Most common cause • Brief episodes triggered by head movement • No hearing loss • Positive Dix-Hallpike test • Treated with the Epley manoeuvre 2️⃣ Vestibular Neuritis • Acute severe vertigo lasting days • Often follows a viral illness • Nausea and vomiting common • No hearing loss 3️⃣ Ménière Disease • Recurrent episodes of vertigo • Fluctuating hearing loss • Tinnitus and aural fullness • Usually unilateral 4️⃣ Vestibular Migraine • Vertigo associated with migraine features • Photophobia, phonophobia, aura • May occur without headache 5️⃣ Labyrinthitis • Vertigo + hearing loss • Often post-viral • Auditory and vestibular symptoms occur together 6️⃣ Acoustic Neuroma (Vestibular Schwannoma) • Progressive unilateral hearing loss • Tinnitus • Gradual onset imbalance or vertigo 7️⃣ Central Causes 🚨 • Stroke • Multiple sclerosis • Cerebellar tumours • Brainstem lesions ⚠️ Red Flags Suggesting a Central Cause 🚨 Diplopia 🚨 Dysarthria 🚨 Limb weakness 🚨 Severe ataxia 🚨 New headache 🚨 Persistent neurological deficits 🩺 Clinical Approach ✔️ Take a careful history ✔️ Examine for nystagmus ✔️ Perform the HINTS examination when appropriate ✔️ Assess hearing ✔️ Look for focal neurological signs 💡 High-Yield Pearl Peripheral vertigo is common, but never miss a central cause. Remember: 🧠 Acute vertigo + neurological signs = Stroke until proven otherwise. 📚 Save this post and visit our website for innovative high-yield medical notes: MedicoNotes.com #Vertigo #Neurology #BPPV #MeniereDisease #vestibularneuritis
