Temperature from which area more accurately reflect core body temperature?
Rectal temperature (0.4 C higher than oral and 0.8 C higher than axillary)
The most common definition of fever uses a core temperature of
38.3 C and above
Palpable lymph nodes in this area are always pathologic
Epitrochlear nodes

• S → Salmonella typhi
• F → Francisella tularensis
• B → Brucella spp.
• C → Coxiella burnetii (Q fever)
• L → Leptospira interrogans
• L → Legionella pneumophila
• M → Mycoplasma pneumoniae
• R → Rickettsia spp.
• C → Corynebacterium diphtheriae

What is the normal CSF profile?
WBC <5/µL (mostly lymphocytes)
• Gram stain: Negative
• Glucose: 40–85 mg/dL
• Protein: 15–45 mg/dL
• Opening pressure: 50–180 mmH₂O
CSF profile in bacterial meningitis?
• WBC: >1000/µL
• Cells: ↑ PMNs (≥80%)
• Gram stain: Positive (>60% cases)
• Glucose: <40 mg/dL
• Protein: >100 mg/dL
• Opening pressure: >300 mmH₂O
• Common causes: Streptococcus pneumoniae, Neisseria meningitidis
CSF profile in viral meningitis?
• WBC: 25–500/µL
• Cells: Predominantly lymphocytes
• Gram stain: Negative
• Glucose: Normal
• Protein: 20–80 mg/dL
• Opening pressure: 100–350 mmH₂O
• Common causes: Enteroviruses
CSF profile in fungal meningitis
• WBC: 40–600/µL
• Cells: Lymphocytes or PMNs (depending on organism)
• Gram stain: Rarely positive
• Glucose: ↓ to normal
• Protein: 150–300 mg/dL
• Opening pressure: 160–340 mmH₂O
• Common causes: Candida, Cryptococcus, Aspergillus
CSF profiles summary
• Bacterial = PMNs + ↓ glucose + ↑↑ protein + very high pressure
• Viral = Lymphocytes + normal glucose + mild protein ↑
• Fungal/TB = Lymphocytes + ↓/low glucose + ↑ protein + high pressure
• Parasitic = Eosinophils + normal glucose + ↑ protein + normal pressure
• Encephalitis = Lymphocytes + normal glucose + mild ↑ protein + pressure normal/↑
