For each scenario below, choose the most appropriate answer from the list above. Each option may be used once, more than once or not at all.

 

1. A patient presents with rigors and a temperature of 40°C. After several hours, he begins to perspire excessively, and there is a gradual fall in temperature. Upon taking his history, it is found that he had similar symptoms 18 months ago after returning from a holiday in Brazil. How regularly would the cycle of symptoms be expected to occur?

 

2. An 18-year-old Indonesian female is admitted with a fever and nausea. She says she has had such symptoms for a few years, and also mentions that her urine has sometimes been red in colour. What is the diagnosis?

 

3. A 25-year-old male has returned from a holiday to Papua New Guinea 3 weeks ago. He has a distended abdomen and complains of feeling hot and sweaty. Microscopy of the thin blood film reveals Schüffner’s dots. What is the likely diagnosis?

 

4. A 15-year-old male has just returned from a family holiday visiting relatives in Nigeria. He complains of a headache, nausea and abdominal pain. His mother, who travelled with him, has no symptoms. What component of his mother’s blood explains her lack of symptoms?

 

5. A 46-year-old female has just returned from a tour of Asia. She complains of a fever and malaise. She says her symptoms occur in cycles every few days, but cannot be specific about the timings. What finding in her blood would make a diagnosis of P.ovale most likely?
