1

What's septic shock?

* Mostly hypovolemic, histamine makes the capillaries leaky which causes the drop in blood volume
* SIRS (Systemic Inflammatory Response Syndrome)

2

Anthrax is caused by?

Bacillus anthracis, it's the spores you have to worry about

What are the three types of anthrax?

* Cutaneous anthrax
* GI anthrax
* Inhalation (pulmonary) anthrax

5

What is pulmonary edema?

Fluid in the lungs

6

What causes pulmonary edema?

Capillaries leakage, 100% mortality rate if untreated

7

What's GAS gangrene caused by?

Clostridium perfringens

8

How do you treat GAS gangrene?

Antibiotics and hyperbaric chamber

9

What does a hyperbaric chamber do?

Big tank with pressurized air, you're forcing air into the wounds, 02 is toxic to anaerobes

10

Who's at risk for GAS gangrene?

Diabetics and chronic wounded individuals

11

What are the two types of black plague?

1) Bubonic plague
2) Pneumonic plague

12

What causes Lyme disease?

* Ticks

What's the best way to diagnose the malaria?

Blood smear and if you see any protozoans including the ring stage in the blood smear, it's a definite diagnosis.

20

What are the three different stages of Lyme disease?

1) Muscular rash
2) Neurological complications (Facial tics, Facial paralysis, meningitis encephalitis)
3) Athro symptoms (arthritis in the joins)
