|The detective sits facing the window while he awaits the arrival of his trainees.|
|Henle||Here’s a case that is going to make you smile.|
|Nephron||(curious): Finally. Anyone for some Coke?|
|Henle||I shall take some Coke, thanks. By the way, it’s a case of hypophosphatemia.|
|Nephron||(smiling): Ah, yes. Electrolyte disorders. The best part of nephrology, and phosphate stuff is always entertaining.|
|Aldo||This is a 71-year-old woman with a phosphorus level of 1.4 mg/dL, but ranging from 1.4 to 2.4 mg/dL.|
|Nephron||(interrupting): That would be good enough.|
|Henle||Yes, Dr. Nephron, we did want to let you know that she has a GFR >60 mL/min, and there’s no mention of any diarrhea.|
|Henle||(whispering to Aldo): He likes to stop at only one electrolyte value.|
|Nephron||How do we categorize the causes of hypophosphatemia?|
|Aldo||Renal loss, extrarenal loss, and shifting; works for all electrolytes in nephrology (almost all).|
