Review the subsequent clinical profiles highlighting distinct environmental or occupational exposures. Select the most appropriate infectious etiology for each patient based on their detailed medical and social history.
- A 32-year-old livestock farmer who recently assisted in birthing sheep and now presents with a sudden-onset high fever, severe headache, and signs of atypical pneumonia.Coxiella burnetii
- A 28-year-old meatpacker working in a cattle processing facility who reports a multi-week history of undulating fevers, profound night sweats, and diffuse arthralgias.Brucella species
- A 45-year-old landscaper who developed a painless erythematous papule that ulcerated after clearing wild brush, followed by painful regional lymphadenopathy.Francisella tularensis
- A 50-year-old avid cave explorer presenting with fever, nonproductive cough, and bilateral hilar lymphadenopathy after a recent expedition in the midwestern United States.Histoplasma capsulatum
Cevap
The livestock farmer with atypical pneumonia matches Coxiella burnetii; the meatpacker with undulating fever matches Brucella species; the landscaper with an ulceroglandular lesion matches Francisella tularensis; and the cave explorer with hilar lymphadenopathy matches Histoplasma capsulatum.
Each diagnosis is established through distinct elements of the patient's medical and social history. Exposure to infected sheep placentas causes Q fever. Abattoir workers handling cattle are at risk for Brucellosis. Landscaping exposes workers to vectors carrying Tularemia, presenting as ulceroglandular disease. Spelunking in the Midwest exposes explorers to Histoplasma in bat guano.
