Question 2
You work in a remote, resource-poor location in Southeast Asia and your 24 year old patient comes in with fever, aggressive behavior and hydrophobia. You suspect rabies.
What are the chances of survival in this patient?
A: Negligible
B: 5 percent
C: 10 percent
D: 20 percent
The correct answer is A.
Rabies is caused by a neurotropic lyssavirus and is transmitted via saliva of infected animals.
The chance of survival once symptoms appear are negligible.

Question 3
A bite by which of the following animals is the most common cause of rabies in the previously (question 2) described patient?
A: Rabbit
B: Reindeer
C: Dog
D: Bat
The correct answer is C.
In resource-poor countries, rabid dogs account for 90 percent or more of reported cases of rabies transmitted to humans. Reindeer actually can carry rabies. It cannot be carried by reptiles, amphibians, rabbits, or insects.
EM@3AM: Rabies
Question 4
Okay, bonus question on rabies. A very controversial and aggressive treatment protocol that includes therapeutic coma, ketamine infusion and amantadine was developed in 2004. Experts advise against the use of this treatment combination due to lack of supportive evidence.
What is the name of this protocol?
A: Madison protocol
B: Chicago protocol
C: Minneapolis protocol
D: Milwaukee protocol
The correct answer is D.
Rabies was covered on EM@3AM last week.
The Milwaukee protocol was used to treat a 15 year old girl in 2004. The girl survived. However, the effectiveness of this protocol remains very poor in subsequent studies.
EM@3AM: Rabies

Question 6
Fitz-Hugh Curtis Syndrome (FHCS), also known as perihepatitis is characterized by inflammation of the liver capsule and surrounding peritoneum with “violin-string” adhesion formation.
Which of the following patients is most likely to contract FHCS?
