Yikes! This is an older patient who has diabetes, hypertension, atrial fibrillation, chronic constipation, and a recent URI who had no eye symptoms and was quite unaware of this finding until he looked in a mirror. His visual acuity is unchanged. There is no photophobia, discharge, or foreign body sensation.

Number the Stars

This 19 month old girl was brought in for 4 days of fever to 104 degrees (40C). She was slightly irritable, but otherwise active, well-appearing, and alert. The mother was concerned about the fever, but this morning the fever broke abruptly. However, you do notice this rash, starting on the neck and trunk and spreading to the face and extremities. It is blanching, flat, and not itchy.

Challenge: What's the cause of these symptoms?

A patient comes to your office complaining of longstanding depressed mood for at least several years. He feels "depressed" on "many days," and this is accompanied by poor appetite, poor sleep habits, low energy, poor self esteem, and poor concentration. However, he does not feel this way for "most of the day nearly every day for two consecutive weeks." Instead, it appears to be more of a chronic feeling rather than an episodic one. He does not have psychomotor agitation or retardation, thoughts of guilt or worthlessness, thoughts of suicide, or symptoms of mania.

Two Passengers

A 30 year old G2P1 woman at 28 weeks gestation is taken to the emergency department after a car accident. She was T-boned by a car which hit the passenger's side, but likely she was on the driver's side. On arrival, she says she "can't catch her breath."

The patient is afebrile. Heart rate is 100, blood pressure 100/60, respiratory rate 14, O2 sat 100% on room air. Extremity exam shows mild peripheral edema and a small water hammer pulse (rapid rise and brisk collapse). The JVP is easily visible. The apical impulse of the heart is at the fourth intercostal space, midclavicular line; it feels relatively hyperdynamic, though not sustained. Heart sounds are easily audible including a widely split S1, an S3, and a 2/4 systolic ejection murmur over the pulmonary and tricuspid areas. There is also a venous hum.

EKG shows a left axis deviation, left atrial enlargement, and an inverted T wave in lead III. The CXR shows mild cardiomegaly with increased pulmonary vascular markings. Hemoglobin is 11, hematocrit is 31, WBC 14,000, platelets 250. ABG shows a PaCO2 of 32, PaO2 of 107, and calculated HCO3 of 20. Creatinine is 0.4.

Challenge: The attending says, "I checked out the fetus and the fetus is fine, but tell me about the mother."
