Hyponatremia is commonly defined as a serum sodium concentration below 135 meq/L but can vary to a small degree in different clinical laboratories [1,2]. The dilutional fall in serum sodium is in most patients associated with a proportional reduction in the serum osmolality (ie, to a level below 275 mosmol/kg), but there are some exceptions.
The iron worker, Gary Russo, sounded like Frank Sinatra and wowed pedestrians a few years ago with his singing by a 2nd Avenue subway construction site in Manhattan during his lunch breaks.
He was singing there in early 1939, when he was talent spotted by trumpeter Harry James, who had organized his own big band after leaving Benny Goodman, which was another famous big band leader of that era. Harry James hired Sinatra as a singer in his band and Frank made his first recording on July 13, 1939.
