A vibrant, color-coded medical study sheet titled "🦠 BACTERIAL INFECTIONS OF CNS β€” 5-Minute Revision Sheet" designed like a premium medical poster with multiple sections: TOP SECTION (dark navy header): Large title "BACTERIAL INFECTIONS OF THE CNS" with subtitle "Meningitis | Brain Abscess | Spinal Epidural Abscess" with small bacteria icons SECTION 1 β€” MIND MAP (coral/orange background): Central bubble "Bacterial CNS Infections" branching out to: Meningitis, Brain Abscess, Spinal Epidural Abscess (SEA), Tuberculous Meningitis. Each branch with small colored sub-nodes. SECTION 2 β€” COLOR-CODED TABLE "ORGANISMS BY AGE GROUP" (teal header): | Age Group | Key Organisms | Empirical Antibiotic | | Neonates (<1mo) | Group B Strep, E. coli, Listeria | Ampicillin + Cefotaxime | | Children 1mo–18yr | N. meningitidis, S. pneumoniae, H. influenzae | Vancomycin + Ceftriaxone | | Adults <50yr | S. pneumoniae, N. meningitidis | Vancomycin + Ceftriaxone | | Adults >50yr / Immunocomp. | + Listeria monocytogenes | + Ampicillin | | Post-neurosurgery/Trauma | Staph aureus, GNB, Pseudomonas | Vancomycin + Cefepime | Table rows alternating white and light teal. SECTION 3 β€” FLOWCHART "PATHOGENESIS" (purple background): Nasopharyngeal colonization β†’ Mucosal invasion β†’ Bacteremia β†’ Cross BBB into CSF β†’ Bacterial proliferation β†’ Cytokine release β†’ Inflammation + Cerebral edema β†’ ↑ICP β†’ Brain herniation (if untreated) With small arrows between each step in a horizontal flow, color gradient from light to dark purple. SECTION 4 β€” CSF COMPARISON TABLE (yellow/amber header): | Parameter | Bacterial | Viral | TB | Normal | | Cells | PMNs 100–1000s | Lymphocytes 50–1000 | Lymphocytes | <5 | | Glucose | <40 mg/dL / <50% serum | Normal | Very low | 45–80 mg/dL | | Protein | >100 mg/dL | Mildly elevated | Very elevated | 15–45 mg/dL | | Pressure | Elevated | Normal/↑ | Elevated | 7–18 cmH2O | | Gram stain | Positive 60–90% | Negative | AFB stain | Negative | SECTION 5 β€” CLINICAL FEATURES + COMPLICATIONS (green section): Classic triad: πŸ”₯ Fever + πŸ€• Headache + πŸ”’ Neck stiffness (Kernig's & Brudzinski's signs) Complications box: SIADH | Cerebral edema | Vasculitis | Hydrocephalus | Deafness | Brain abscess SECTION 6 β€” TREATMENT FLOWCHART (red/orange): Suspected Bacterial Meningitis β†’ Blood cultures β†’ CT (if focal neuro signs) β†’ LP β†’ Start empirical ABx within 60 min β†’ Add Dexamethasone (before/with 1st ABx dose) β†’ De-escalate based on culture/sensitivity Treatment box: Vancomycin + Ceftriaxone Β± Ampicillin (for Listeria coverage >50yr) Dexamethasone 0.15 mg/kg q6h Γ— 4 days SECTION 7 β€” BRAIN ABSCESS MINI-TABLE (pink section): Sources: Sinusitis (frontal lobe), Otitis media (temporal lobe/cerebellum), Hematogenous (multiple), Trauma/Surgery Organisms: Strep, Staph aureus, Bacteroides, mixed anaerobes Treatment: Drainage + Vancomycin + Ceftriaxone + Metronidazole BOTTOM FOOTER β€” KEY MNEMONICS (light blue): "SHiNE" β†’ S. pneumoniae, H. influenzae, N. meningitidis, E. coli (common meningitis organisms) Kernig's sign = Knee kept extended (pain on extension from 90Β° hip flex) Brudzinski's sign = Bending neck β†’ Bending knees Overall design: Clean, medical textbook style, richly color-coded with distinct colored headers per section, small medical icons, readable fonts, professional layout fitting an A3 portrait poster. High detail, no blurry text.

Bacterial Infections of CNS - 5-Minute Revision Sheet
Here is your complete Bacterial Infections of CNS visual study sheet, built from authoritative textbook content (Goldman-Cecil Medicine, Bradley & Daroff's Neurology, Rosen's Emergency Medicine, Jawetz Medical Microbiology). Here's what's packed into it:

What's covered in this sheet:

πŸ”΅ Mind Map - Central branching of all CNS bacterial infections: Meningitis, Brain Abscess, SEA, TB Meningitis
🟒 Age-Based Organism Table
  • Neonates: Group B Strep + E. coli + Listeria
  • Children: N. meningitidis dominant
  • Adults <50: S. pneumoniae (70%+ of cases) + N. meningitidis
  • Adults >50 / immunocompromised: Add Listeria coverage with Ampicillin
  • Post-op/trauma: Staph aureus + GNBs
🟣 Pathogenesis Flowchart Nasopharyngeal colonization β†’ BBB breach β†’ CSF proliferation β†’ Cytokine storm β†’ Cerebral edema β†’ ↑ICP
🟑 CSF Comparison Table Bacterial vs Viral vs TB vs Normal - cells, glucose, protein, pressure, gram stain
πŸ”΄ Treatment Algorithm Blood cultures β†’ CT if needed β†’ LP β†’ Empirical ABx within 60 min β†’ Dexamethasone (before/with 1st dose)
🩷 Brain Abscess Quick Table Source β†’ lobe affected β†’ organisms β†’ drainage + triple therapy
πŸ”΅ Mnemonics
  • SHiNE for common organisms
  • Kernig's vs Brudzinski's sign differentiation
Note: Apurba Sastry's "Review of Microbiology & Immunology" is not in the library database, so this sheet was compiled from equivalent standard references covering the same exam-relevant content.
