I picked up an old issue of the New England Journal of Medicine and came across a couple of interesting picture stories. The first was on a serious HF accident (free access). The poor victim was cleaning an old facility used for glass etching when a pipe containing 70% HF burst on him. The treatment involved pumping Mg²⁺ and Ca²⁺ into his veins and arteries.  You can actually see the calcified precipitates on his skin. Yum: 

The second pict-o-story was based on a tub of fluorescent urine.  When admitted to the ER, the urinator was believed to have ingested anti-freeze.  The doctors noted that the patient’s pee fluoresced under UV light, and they concluded that this was probably the result of the anti-freeze’s being spiked with dye.  The wording of the paper made it seem like the doctors suspected the chromaphore was fluorescein, which is often added to anti-freeze to aid in the detection of radiator leaks.

The only problem is that the fluorescence was blue, not green, which is the color you’d expect from fluorescein.  Some other guys noticed the same thing and sent a letter to the editor, so who knows what’s going on?  In their defense, the doctors noted that there are plenty of opportunities for false negatives and false positives if this were to actually be used as a test for anti-freeze ingestion, so it appears the only reason this story was published was as an excuse to run a pretty picture of glowing urine.  I can respect that.

Lastly, I should add that both of the patients survived and apologize for ruining your appetites.
