Clinical Case Study What's Ailing the Bird Enthusiast?
A 72-year-old man arrives at a hospital emergency room with signs and symptoms of serious pulmonary infection. He complains of a deep cough, blood-tinged sputum, night sweats, and weight loss. His liver and spleen feel enlarged upon physical examination. X-ray studies of his chest suggest tuberculosis, but a tuberculin skin test is negative, as is an HIV test. The man, an Ohio native, has recently traveled to Africa and Asia. In addition, he is an avid bird enthusiast who likes to feed pigeons. He also keeps many bird feeders on his balcony, which attracts numerous birds, and he spends an hour a day cleaning up bird droppings.
Skin tests are positive for histoplasmosis but inconclusive for coccidioidomycosis and blastomycosis.
- 1. What is the most likely infecting agent? How do you suppose this individual acquired the disease?
- 2. Is this disease unusual in people who work with birds?
- 3. Given that some tests were inconclusive, what other tests or lab work would aid in arriving at a specific diagnosis?
- 4. What treatment would most likely be prescribed?

A journalist returning from a trip experienced severe fever, vomiting, chills, and muscle aches, followed by symptoms of meningitis and kidney failure. Early tests were negative for septicemia; throat cultures were negative; and penicillin was an effective treatment. Doctors believed the patient’s work in the jungles of South America was a possible clue to his disease. What do you think might have been the cause?arrow_forwardCLINICAL CASE STUDY: A 65-year-old woman recently discharged from the hospital following a myocardial infarction (heart attack) returns to the hospital emergency room complaining of the sudden onset of pain in her right lower extremity. The attending physician noticed that the patient leg is also pale and cool from the knee distally. Furthermore, he is unable to detect a pulse over the posterior dorsal pedal and popliteal arteries. A good femoral pulse, however, is palpable in the inguinal region. Upon questioning, the patient states that she was discharged from the hospital with blood- thinning medication because tests had revealed that the heart attack had caused a blood clot to form within her heart. She added that the doctors were worried that a piece of the clot could break off and go to other parts of the body. QUESTIONS: 1. Explain how the patient heart attack several weeks earlier could have led to her current leg complaints. 2. In which side of her…arrow_forward
