Mustard

A patient with systemic lupus erythematosus and systemic vasculitis is being counseled about taking the drug shown above. Within days to weeks of treatment, she will need her blood count closely followed because she may have decreased granulocytes, followed by thrombocytopenia, followed by anemia. Obviously, this increases her risk of infection. She is also counseled that this drug may cause premature ovarian failure, ovarian fibrosis, and permanent infertility. A pregnancy test is checked because the drug is highly teratogenic. Long-term, she needs to watch for lymphoma and other malignancies as well as cystitis and bladder cancer resulting from a toxic metabolite excreted in the urine.

Bat Man

A 40 year old man presents with insidious gradual shortness of breath. He gets dyspneic on exertion and has a cough, fatigue, weight loss, and low-grade fever. His physical exam is pretty much normal. His labs show polycythemia, hypergammaglobulinemia, and increased LDH. Chest X-ray is below:

High resolution CT scan shows homogeneous ground glass opacities. Pulmonary function tests show a restrictive ventilatory defect. A bronchioalveolar lavage results in an opaque milky fluid which settles upon standing.

Challenge: Aha! Your diagnosis is...?

Ouch

Oops - this case was scheduled to post last Thursday but didn't trigger.

A child is brought in by ambulance as a major trauma. He was hit by a slow moving car which pinned him against the wall. When EMS found him, his chest was pinned against the bumper. There was no injury at the neck. He is stable on your primary survey of airway, breathing, circulation, disability, and exposure. On your secondary trauma survey, you note bilateral conjunctival hemorrhage, facial edema, ecchymoses, and petechiae on the upper chest and face. Fortunately, the prognosis for this is generally favorable.

Challenge: What happened?

Leave It Up To

As I just certified in advanced trauma life support, this week will be trauma cases.

A woman is brought into your emergency department after a car crash. She was only wearing a lap belt, and it was positioned a little high, above her pelvic bones. She has a clear seat belt sign on her abdomen. Her neurologic exam is grossly normal. Lumbar spine films are shown above. By chance, you also order a CT abdomen which shows duodenal injury. She's taken immediately to the operating room.

Challenge: Your intern asks what the radiologist has arrowed on the X-ray. What fracture does she have?
