Doctor's Day
In the U.S., National Doctor's Day always falls on March 30th. National Doctor's Day observance dates back to 30 March 1933 when it was first conceived by Eudora Brown Almond of Winder, Georgia. The day marks the anniversary of the first use of general anesthesia that occured in 1842. The U.S. House of Representatives adopted a resolution commemorating Doctor's Day on 30 March 1958. National Doctor's Day was, however, not established until March 30, 1990 when President Bush signed the resolution into law. The first Doctor's Day was celebrated nationwide in the U.S. on March 30, 1991.

Pleural Empyema
Pleural empyema refers to the infection of pleural space, which is located between two lining sheets that wrap around lungs. In healthy people, this pleural space is deflated and does not contain fluid. This space, however, may expand and contain abnormal fluid which usually leaks in from infected or injured lungs. If pus or bacteria are found in this abnormal fluid, pleural empyema is diagnosed.

Pleural empyema can become deadly if left untreated.
Treatment requires the placement of a chest tube which helps drain pus or infected fluid. Also, 4-6 weeks of antibiotics that help kill both aerobes and anaerobes are required.
In some cases empyema walls become thickened scars that prevent lungs from expanding properly, even after infection is successfully treated. These conditions are called "trapped lungs" and treating doctors may recommend decortication.
