|
o Clubbing
|
produced by soft tissue growth at the nail bed and identified by noting a greater anterior-posterior distance at the nail bed as compared to the same distance at the distal interphalangeal joint (also creates a nail-finger angle >180 degrees). Clubbing typically occurs in response to thoracic disease, including cyanotic congenital heart disease, cystic fibrosis, pulmonary fibrosis, lung cancer, and severe hepatic cirrhosis (with hepato-pulmonary syndrome). Although reported in severe COPD, other pathology (e.g. lung cancer) must be excluded before accepting COPD as the sole cause.

|
|
o Hyperextensibility
|
defined as ability to stretch the skin >4 cm at forearm or neck before feeling resistance; this is a finding in Ehlers-Danlos syndrome
