A patient's lactate continues to rise despite normalization of blood pressure. What important assumption should be questioned?

Laryngeal Nerve Injury 🔵 1. Superior Laryngeal Nerve (SLN) 🔸 External Branch → Cricothyroid ➡️ Injury Leads To: • Weak/soft voice • Loss of pitch (monotone voice) • Vocal cord movement largely preserved 🔸 Internal Branch → Sensory (Supraglottic) ➡️ Injury Leads To: • ↓ Cough reflex • Aspiration risk 🔴 2. Recurrent Laryngeal Nerve (RLN) 🎯 Motor: All intrinsic laryngeal muscles (except cricothyroid) 🎯 Sensory: Below vocal cords ➡️ Unilateral Injury: • Hoarseness • Weak voice • Vocal cord in paramedian position ➡️ Bilateral Injury: • Stridor • Severe airway obstruction • Emergency airway may be required 🧠 Mnemonic 🔁 "RECurrent = REst of muscles" 🎵 "SLN External = Singer's Loss (pitch)" Concepts.

🚨 #TrapOfTheDay 🫁 Asthma patient eosinophilia neuropathy sinusitis 👉 Don’t stop at “allergic asthma” ❗ ❌ Allergic asthma ❌ Simple eosinophilia ✅ EGPA (Churg–Strauss Syndrome) 📌 Classic Clues: • Severe asthma • Peripheral eosinophilia • Chronic sinusitis • Vasculitis with neuropathy 🧠 What is EGPA? A small-vessel necrotizing vasculitis associated with eosinophilic inflammation. 📌 Common Features: ✅ Asthma (almost always present) ✅ Mononeuritis multiplex / neuropathy ✅ Pulmonary infiltrates ✅ Skin purpura ✅ Eosinophilia 🧪 Important Marker: p-ANCA (MPO-ANCA) may be positive ⚠️ MCQ Trap: Asthma eosinophilia ≠ simple allergy ❌ 👉 Add neuropathy/vasculitis → Think EGPA 💡 Exam Pearl: Asthma eosinophils vasculitis = EGPA until proven otherwise 👍 = Clear 🔥 = Corrected mistake #Medicine #EGPA #ChurgStrauss #Vasculitis #Pulmonology #Rheumatology #NEETPG #INICET #Medx26 #MedEd

🚨 #ECGRevision | P Wave Abnormalities 🫀 P Mitrale = Left Atrial Enlargement (LAE) 📌 ECG Clues: • Broad, notched “M-shaped” P wave • Duration > 0.12 sec • Best seen in Lead II 📌 Lead V1 clue (Morris Index): Terminal negative P component ✅ Depth >1 mm ✅ Duration >0.04 sec 📌 Common Causes: • Mitral stenosis • LV failure • Dilated cardiomyopathy 🫁 P Pulmonale = Right Atrial Enlargement (RAE) 📌 ECG Clues: • Tall, peaked P wave • Height > 2.5 mm • Best seen in Lead II 📌 Common Causes: • Pulmonary hypertension • COPD • Tricuspid stenosis • Pulmonary stenosis 🧠 Memory Trick (Exam Gold): ✅ P Pulmonale = Peaked ✅ P Mitrale = M-shaped ⚠️ MCQ Trap: Tall P wave ≠ LAE ❌ 👉 Broad/notched = LAE 👉 Tall/peaked = RAE 💡 Exam Pearl: “M” in Mitrale = M-shaped P wave 👍 = Revision done 🔥 = ECG concepts clear #ECG #Cardiology #PMitrale #PPulmonale #NEETPG #INICET #Medx26 #MedEd

✅ Correct Answer: B) Allergic Contact Dermatitis ⚠️🖤 This is the classic reaction seen with “Black Henna” tattoos. 🔬 Why? Natural henna is usually reddish-brown and relatively safe 🌿 But so-called black henna often contains: 🧪 Para-phenylenediamine (PPD) —a potent sensitizer added to make the tattoo: ⚫ Darker ⚡ Faster drying ⏳ Longer lasting Unfortunately, PPD is notorious for causing: 🔥 Allergic Contact Dermatitis (Type IV hypersensitivity) --- 🩺 Clinical Clues in This Image 📍 Lesion perfectly matches the tattoo pattern 📍 Erythematous, raised, eczematous plaque 📍 Delayed hypersensitivity appearance after exposure This geometric “exact-outline” reaction is highly characteristic of contact allergy. --- ❌ Why the Other Options Are Wrong A) Irritant Contact Dermatitis Usually: ⚠️ More immediate ⚠️ Burning > itching ⚠️ Less immune-mediated Black henna reactions are classically allergic. --- C) Phytophotodermatitis ☀️🌿 Occurs after plant psoralen exposure UV light: 🍋 Lime juice 🌱 Celery 🌿 Parsley Typically causes: 🟤 Hyperpigmented streaks/blisters —not a sharply tattoo-shaped eczematous plaque. --- D) Tinea Corporis 🍄 Would show: ⭕ Annular scaly plaques ⭕ Central clearing ⭕ Fungal spread pattern Not a tattoo-conforming dermatitis. --- 🧠 High-Yield Pearl: ⚠️ Black henna ≠ pure henna Whenever you see severe inflammation exactly matching a temporary tattoo pattern, think: 🖤 PPD-induced Allergic Contact Dermatitis

Brivaracetam binds with high affinity (15–30x stronger than levetiracetam) to synaptic vesicle protein 2A (SV2A) in the brain. This modulates neurotransmitter release (mainly reducing excessive excitatory release like glutamate) during high-frequency neuronal firing, which helps prevent seizures. It acts primarily presynaptically on recycling synaptic vesicles.
