🧬 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)

🌀 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.

💡 Guide to Hypothyroidism Management

⸻

1️⃣ Clinical Features

🔹 Common Symptoms
➊ Cold intolerance
➋ Fatigue
➌ Weight gain
➍ Constipation
➎ Bradycardia
➏ Mental slowing

📌 Suspect hypothyroidism in patients with metabolic slowing and fatigue

⸻

2️⃣ Diagnosis — TSH is the Gold Standard

🧪 Primary Hypothyroidism
⬆️ TSH + ⬇️ Free T4

🧪 Subclinical Hypothyroidism
⬆️ TSH + Normal Free T4

🧪 Central Hypothyroidism
⬇️/Normal TSH + ⬇️ Free T4

⚠️ Central causes suggest pituitary/hypothalamic disease

⸻

3️⃣ Investigating the Cause

🔬 Common Tests
➊ Anti-TPO antibodies
➋ Anti-thyroglobulin antibodies

📌 Hashimoto thyroiditis is the most common cause

🧠 In suspected central disease, assess:
• ACTH/cortisol
• Prolactin
• LH/FSH & GH

⸻

4️⃣ Treatment of Choice

💊 Levothyroxine (T4)

📌 Initial Dosing
➊ Healthy adults → ~1.6 mcg/kg/day
➋ Elderly/CAD → Start low (12.5–25 mcg/day)
➌ Pregnancy → Increase dose by 30–50%

⸻

5️⃣ Important Dosing Tips

⏰ Take on an empty stomach

🚫 Separate from:
• Iron
• Calcium
• Antacids

📌 Recheck TSH every 6 weeks after dose changes

⸻

6️⃣ Subclinical Hypothyroidism

✅ Usually treat if:
• TSH >10 mIU/L
• Symptomatic
• Positive antibodies
• Pregnancy/fertility concerns

⸻

7️⃣ Myxedema Coma 🚨

⚠️ Features
• Hypothermia
• Bradycardia
• Hypotension
• Altered mental status

🚑 Management
➊ Airway/supportive care
➋ Warm IV fluids
➌ IV levothyroxine
➍ IV hydrocortisone

⸻

💡 Clinical Pearls

➊ High TSH + low FT4 = overt hypothyroidism
➋ Low/normal TSH + low FT4 = central hypothyroidism
➌ Exclude adrenal insufficiency before high-dose thyroid replacement
➍ Pregnancy increases levothyroxine requirements

🧠 Stroke Localization Made Simple

⸻

1️⃣ MCA Stroke (Middle Cerebral Artery)

➊ Face & arm weakness > leg weakness
➋ Contralateral sensory loss
➌ Dominant side → Aphasia
➍ Non-dominant side → Neglect

💡 Remember:
MCA = “M” for Mouth & aRM involvement

⸻

2️⃣ ACA Stroke (Anterior Cerebral Artery)

➊ Leg weakness > arm weakness
➋ Personality changes
➌ Abulia (loss of motivation)
➍ Urinary incontinence

💡 Think:
ACA affects the medial brain → lower limb area

⸻

3️⃣ PCA Stroke (Posterior Cerebral Artery)

➊ Contralateral homonymous hemianopia
➋ Visual symptoms
➌ Alexia without agraphia
➍ Macular sparing

💡 Classic clue:
“I can write… but I can’t read”

⸻

4️⃣ Lateral Medullary Syndrome (PICA)

➊ Dysphagia & hoarseness
➋ Vertigo, nystagmus, ataxia
➌ Ipsilateral facial sensory loss
➍ Contralateral body pain/temperature loss
➎ Horner syndrome

💡 Crossed findings = brainstem lesion

⸻

5️⃣ Medial Medullary Syndrome (ASA)

Remember the “3 M’s”:

➊ Medial lemniscus → ↓ vibration/proprioception
➋ Motor pathway → contralateral weakness
➌ Medulla CN XII → tongue deviation

⸻

🎯 Stroke localization becomes easy when you recognize the pattern!

💡HYPOXIA: LOW O₂, MANY CAUSES!

Hypoxia is a sign, not a diagnosis. Understanding the mechanism helps you identify the cause and treat it quickly.

⸻

1️⃣ V/Q Mismatch

📍 Most common cause of hypoxia

🔹 Ventilation and perfusion are mismatched
🔹 Seen in asthma, COPD, pneumonia

💎 Pearl:
Improves with supplemental oxygen.

⸻

2️⃣ Shunt

📍 Blood bypasses ventilated alveoli

🔹 No gas exchange occurs
🔹 Seen in ARDS, severe pneumonia, atelectasis

💎 Pearl:
Does NOT significantly improve with oxygen.

⸻

3️⃣ Diffusion Defect

📍 Impaired gas transfer across alveolar membrane

🔹 Pulmonary fibrosis
🔹 Interstitial lung disease

💎 Pearl:
Worse during exercise.

⸻

4️⃣ Hypoventilation

📍 Reduced alveolar ventilation

🔹 CNS depression
🔹 Neuromuscular disorders
🔹 Obesity hypoventilation

💎 Pearl:
↑ PaCO₂ + ↓ PaO₂

⸻

5️⃣ Low FiO₂

📍 Reduced inspired oxygen

🔹 High altitude
🔹 Poorly ventilated environments

💎 Pearl:
Improves with increased FiO₂.

⸻

6️⃣ Pulmonary Embolism (PE)

📍 Perfusion defect

🔹 Sudden dyspnea
🔹 Pleuritic chest pain
🔹 Tachycardia

💎 Pearl:
Ventilation present, perfusion absent.

⸻

7️⃣ ARDS

📍 Diffuse alveolar injury

🔹 Severe hypoxemia
🔹 Pulmonary edema
🔹 Reduced lung compliance

💎 Pearl:
Refractory hypoxemia despite oxygen therapy.

⸻
💎 High-Yield Exam Pearls

🫁 V/Q Mismatch → Most common

🫁 Shunt → Doesn’t improve with O₂

🫁 Diffusion Defect → Worse on exertion

🫁 Hypoventilation → High CO₂

🫁 Low FiO₂ → High altitude

🫁 PE → Ventilation without perfusion

🫁 ARDS → Refractory hypoxemia
