Chapter 24 - Clinical Corner

You are an avid jogger and living in New York, and Central Park is the place you love to run. It has great scenery and you enjoy watching the horse-drawn carriages taking tourists on sightseeing trips through the park. One morning as you enter the park you are told that it is closed for mosquito spraying and will not be open again for several days because of West Nile virus. Although this ruins your jogging plans, you understand the problem. Several other joggers and drivers of the carriages are not so understanding and demand to know what the problem really is. You want to be helpful.

A. What do you tell them about West Nile virus?

B. Why are they spraying for mosquitoes?

C. Who are the people most at risk of this infection?

D. When one of the joggers points out that the Nile River is thousands of miles away, how do you explain to him about West Nile virus being found in New York City’s Central Park?



Your patient presents complaining of headache and dizziness, which have been going on for more than a month. He has also become forgetful to the point that he can no longer manage the automotive parts store he owns. His medical history shows that he received a kidney transplant two years ago but he has no signs of an infection of the transplanted kidney. He is not taking any medication other than the immunosuppressants required to prevent the rejection of his transplanted kidney. Tests have shown no indication of cardiovascular abnormalities.

A. What are some of the possible explanations for his problems?

B. Does the fact that he is a transplant recipient mean anything?
