You are a fourth-year medical student and super-excited to be doing your first supervised central line procedure on an actual patient. You have done so many central lines on mannequins and simulations. You feel ready. In your excitement, however, you stick yourself with the 22 gauge finder needle after you successfully get a flash-back of the patient’s venous blood. After handing off the procedure to your senior resident, you go into a mild panic. Your patient is a known HIV patient with an unknown CD4 count and viral load. After taking off your gloves and washing your hands, you report this to the attending. Should you start post-exposure prophylaxis medications for HIV?

It’s difficult to concentrate when faced with so many questions whirling in your mind.

Did you know that there was an unexplained spike in Legionnaire’s disease (pneumonia caused by Legionella pneumophila) during the 2009 H1N1 flu pandemic? Since the flu season is rapidly approaching, I thought I would review what Legionnaire’s disease looks like. Yes, they will have a fever, cough, and pneumonia on CXR. These patients are generally pretty sick and almost always need hospitalization. What makes it unique? The trick is to look for extrapulmonary findings, which help to distinguish it from other atypical pneumonias. Relative bradycardia is a sure tip.
