Abnormal Nail Folds may Suggest Abnormal Pulmonary Function

Abnormal nail folds with a pattern indicating systemic sclerosis (SSc) is common in patients with Raynaud's syndrome, shows a study recently published in the Journal of Rheumatology. It can also be present in patients with other forms of connective tissue disease, such as primary Sjögren syndrome, systemic lupus erythematosus, rheumatoid arthritis and mixed connective tissue disease. An SSc abnormal nail growth pattern was also found to be associated with abnormal pulmonary function tests (PFT). Learn more here in this slideshow.
