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].

Sinatra's music has been considered timeless by many. He is one of the best-selling music artists of all time, having sold more than 150 million records worldwide. Born in Hoboken, New Jersey, to Italian immigrants, he began his musical career in the swing era with Harry James and Tommy Dorsey. He found success as a solo artist after being signed by Columbia Records in 1943, becoming the idol of the bobby soxers. He released his first album, The Voice of Frank Sinatra, in 1946.
