Measurements of Laser Doppler flow were performed on the fingertip during heating in a group of normals and in a group of patients with different types of Raynaud's phenomenon. During heating a group of 24 normals was distinguished from a group of 29 primary Raynaud's patients. A group of 17 patients with secondary Raynaud's phenomenon due to scleroderma and 8 patients with arteriographically proven severe vascular occlusive disease of the fingers showed a significantly lower response in comparison to the two above-mentioned groups. Patients with or without slight or severe trophic skin lesions were identified. In patients with scleroderma the maximal vasodilation during heating was inversely related to the number of organs affected. In conclusion, measurements of the hyperaemia during heating may play a role in determining the degree of obstructive vascular involvement in Raynaud's phenomenon.

Botulinum toxin (BoNT) has traditionally been utilized to relieve tension in muscular and connective tissue diseases (CTD). However, its usage has rapidly expanded and now encompasses usage for neurological, gastrointestinal, psychological, cardiovascular, ophthalmology, orthopedics, and more. More recently, its usage has been utilized for sequelae of CTDs such as Raynaud's disease and reduced oral aperture secondary to scleroderma/systemic sclerosis.

Raynaud's phenomenon (RP) is a vascular disease characterized by exaggerated vasoconstriction in response to stressors, mainly cold and emotional stress. This vasoconstriction is mediated solely by alpha 2C-adrenoceptors (α-AR) expressed in vascular smooth muscle cells of dermal arterioles. Several factors, among which is cigarette smoking, are associated with aggravated symptoms of and increased risk for RP.

Montefiore Medical Center, Albert Einstein College of Medicine, Rheumatology, Bronx, NY, USA.
Background: The anti-melanoma differentiation-associated gene 5 (anti-MDA5) antibody-positive dermatomyositis is known for its association with rapidly progressive interstitial lung disease (RP-ILD) and ulcerative skin lesions, often presenting with or without muscle involvement. The aim of this study was to identify distinct clinical and laboratory features that could be used to evaluate disease progression in an ethnically diverse cohort of anti-MDA5 dermatomyositis patients at a U.S.
