Scrofula was therefore also known as the King's Evil . From 1633, the Book of Common Prayer of the Anglican Church contained a ceremony for this, and it was traditional for the monarch (king or queen) to present to the touched person a coin – usually an Angel , a gold coin the value of which varied from about 6 shillings to about 10 shillings. In England this practice continued until the early 18th century, and was continued by the Jacobite pretenders until the extinction of the House of Stuart with the death of the pretender Henry IX . King Henry IV of France is reported as often touching and healing as many as 1,500 individuals at a time.

Pericarditis caused by tuberculosis is difficult to diagnose, because definitive diagnosis requires culturing Mycobacterium tuberculosis from aspirated pericardial fluid or pericardial biopsy , which requires high technical skill and is often not diagnostic (the yield from culture is low even with optimum specimens). The Tygerberg scoring system helps the clinician to decide whether pericarditis is due to tuberculosis or whether it is due to another cause: night sweats (1 point), weight loss (1 point), fever (2 point), serum globulin > 40g/l (3 points), blood total leucocyte count <10 x 10 9 /l (3 points); a total score of 6 or more is highly suggestive of tuberculous pericarditis.  Pericardial fluid with an interferon-γ level greater than 50 pg /ml is highly specific for tuberculous pericarditis.
