Anti-NMDA-Receptor Encephalitis
Anti-NMDA-receptor encephalitis is a severe and treatable immune-mediated disorder which presents with a rapid progression of psychiatric and neuropsychiatric symptoms. Although only first reported as a diagnosis in 2007, an exponential number of cases have since been described, suggesting that the disease is not rare but rather under-diagnosed. Emergency physicians play an important role in recognizing this disorder, as prognosis is largely dependent on early treatment with immunotherapy. [+]

I was a slave to the machinations of my aberrant brain. We are, in the end, a sum of our parts, and when the body fails, all the virtues we hold dear go with it.” – Brain on Fire, Susannah Cahalan [+]
Trick of the Trade: Knee Arthrocentesis
A patient comes into the ED and you suspect septic arthritis to the knee. As you consent the patient for arthrocentesis, you can tell s/he has reservations about a needle being inserted into their knee and left in place while you aspirate. You also think in the back of your mind how tricky it is to sometimes change syringes while keeping the needle in the correct location. Is there another way of tapping the knee without a needle? [+]
