Myasthenia Gravis Poster

Presentation · PPTX

What's on the Poster

The poster is a single wide-format slide (13.3" × 7.5", print-ready) with a deep navy blue design scheme and three full content columns:

🧠 Column 1 — Pathophysiology & Epidemiology

  • Full antibody profile: Anti-AChR (80-90%), Anti-MuSK, Anti-LRP4 with clinical correlations
  • Mechanism: complement activation, receptor destruction, postjunctional fold degeneration
  • Real NMJ diagram from Harrison's showing SNARE proteins, ACh vesicles, agrin, AChE
  • Epidemiology: prevalence, bimodal age distribution, thymus-MG association

🩺 Column 2 — Clinical Features, MGFA Classification & Investigations

  • Cardinal symptoms including ptosis, fatigable weakness, bulbar involvement, respiratory failure
  • MGFA Class I–V classification table
  • Three clinical photographs from medical literature:
    • Ptosis + RNS decrement + CT thymoma triad
    • Tensilon (edrophonium) test — before/after ptosis reversal
    • Ice pack test — bedside cooling test
  • Full investigations table: AChR Ab, anti-MuSK, edrophonium, ice pack, RNS, SF-EMG, CT chest

💊 Column 3 — Treatment, Myasthenic Crisis & Drug Warnings

  • Treatment table: Pyridostigmine → steroids → azathioprine → eculizumab → efgartigimod → thymectomy
  • Crisis management: ICU, plasma exchange, IVIG, hold AChEI, airway protection
  • Drugs to avoid in MG (aminoglycosides, fluoroquinolones, Mg²⁺, β-blockers, checkpoint inhibitors)
