Episode notes
TB's Stealthy Survival Mechanism
- Mycobacterium tuberculosis evades the immune system using mycolic acid and grows very slowly compared to typical bacteria.
- Latent TB involves dormant bacteria within immune granulomas, asymptomatic and non-transmissible.
Assess TB Risk and Symptoms
- Screen patients' social history thoroughly for TB risk factors like exposure and living conditions.
- Ask about chronic respiratory and constitutional symptoms for TB disease suspicion.
Comprehensive TB Physical Exam
- Conduct thorough physical exams focusing on cachexia, lymphadenopathy, lung auscultation, and search for extra-pulmonary signs.
- Remember TB can affect almost any organ, so tailor exam accordingly.
