Textbook Question
Chapter 23, Problem 1CCS
A 20-year-old student was admitted to his college’s student health center with headaches and fever shortly after beginning the fall semester. He had spent his summer working with an international aid organization in Nigeria and had returned to the United States only one week earlier. Gross examination revealed a diffuse rash and numerous insect bites. The young man had spent most of his summer outdoors in rural areas, had taken no prophylactic antimalarial medication, and had spent some time on African game reserves working with the families of local guides. The patient could not specifically remember receiving any of the bite wounds on his body, and he did not always use insect repellent in the field. The young man was admitted to the local hospital, where intermittent fever, nausea, and headache continued. Initial blood smears proved negative for malaria.
- 1. What are some possible protozoan diseases the patient could have contracted in Africa?
- 2. Can this disease be identified from the symptoms alone?
- 3. Based on the pictured blood smear, what would you conclude about the cause of the disease?
- 4. What would the treatment be if the patient had tested positive for malaria?
- 5. What treatment would you now recommend?
- 6. What prevention would you have suggested to this individual?
- 7. Is there a local threat of anyone else contracting this disease from the young man?

Julie Rogers, a 47-year-old patient, calls her physician’s office after leaving her workplace because she quite suddenly felt very tired and nauseated and noticed that her urine was dark. An associate at her workplace told Julie that the sclera of her eyes looked “yellow.” When she contacted her physician, she was told to come directly to the physician’s office for evaluation. When she arrived, as a precaution, Julie was taken to an exam room reserved with a protocol for strict infection control. Her vital signs were temperature 101.6, pulse 94, respirations 26, and blood pressure 148/88. Julie stated that her muscles felt sore. A urine specimen was collected and sent to the laboratory. On physical examination, liver enlargement was noted, as well as mild jaundice of the sclera. Julie’s clinical history was unremarkable, except that she mentioned that she had recently spent time at summer camp as a youth counselor. During this time, she was living in close quarters.

This 19-year-old college student went to the Student Health Services because she had a slowly developing rash on both earlobes, hands and wrist, and around her neck.
Her medical history revealed that she had eczema in childhood. During her early teens, she had facial acne, for which she was given tetracycline. Physical examination revealed a rash of erythema and small blisters, with marked excoriation because of the itching. Her hands were red, scaly, and dry. The rash on her hands was different from the eruptions on her neck and ears. A contact hypersensitivity was suspected.
Follow-up patch tests included a standard battery of agents—rubber, cosmetics, plant extracts, perfumes, nickel, and makeup. Strongly positive reactions for rubber and nickel were observed.
The student was advised to eliminate contact with rubber (e.g., rubber gloves) used at home or on the job. Her jewelry probably contained nickel and was believed to be the source of the irritation to her earlobes, neck, and…
