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 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.
While the song was written in 1936, and sang by various artists of that era, Frank Sinatra didn't sing the song until 1946 while performing You'd Be So Easy to Love on his early radio show. The first studio recording of I've Got You Under My Skin by Sinatra was in 1956 for the album Songs for Swingin' Lovers!. At the time, it became known as one of Sinatra's greatest and signature hits. Several years after, Sinatra re-recorded this song in his 1963 Reprise album, Sinatra's Sinatra.
