Discussion: Sinusitis.

1) On July 8, a woman was given an antibiotic for presumptive sinusitis. However, her condition worsened, and she was unable to eat for 4 days because of severe pain and tightness for the jaw. On July 12, she was admitted to a hospital with severe facial spasms. She reported that on July 5, she had incurred a puncture wound at the base of her big toe; she cleaned the wound but did not seek medical attention. What caused her symptoms? Was her condition due to an infection or an intoxication? Can she transmit this condition to another person?

2) Explain whether each of the following examples is a food infection or intoxication. What is the probable etiological agent in each case?

a) Eighty-two people who ate shrimp in Louisiana developed diarrhea, nausea, headache, and fever from 4 hours to 2 days after eating

b) Two people in Vermont who ate barracuda caught in florida developed malaise, nausea, blurred vision, breathing difficulty, and numbness 3 to 6 hours after eating.

3) Cancer patients undergoing chemotherapy are normally more susceptible to infections. However, a patient receiving an anti tumor drug that inhibited cell division was resistant to salmonella. Provide a possible mechanism for the resistance.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.

Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.

Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.

The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument
