This is why internists are invaluable. And why you can't just read an article or two, or take 500 hours of clinical preceptorships from 8am to 5 pm for a year or "freshen up" after years of taking out gallbladders once the hands are crippled and expect to offer competent independent quality care to patients who don't know the difference between hypertension and hypernatremia. Internal medicine is beast all by itself. As any internist will tell you.
