Raynaud syndrome, also known as Raynaud's phenomenon, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. [1] Typically the fingers, and, less commonly, the toes, are involved. [ 1 ]
Many health conditions can cause autonomic neuropathy. Some common causes of autonomic neuropathy include: Diabetes, which is the most common cause of autonomic neuropathy, can gradually cause nerve damage throughout the body. Injury to nerves caused by surgery or radiation to the neck.
CREST syndrome, also known as the limited cutaneous form of systemic sclerosis (lcSSc), is a multisystem connective tissue disorder.The acronym "CREST" refers to the five main features: calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia.
Raynaud’s phenomenon, which causes parts of the body like the fingers and the toes to go cold and numb, likely stems from two genes, a study published Thursday in the journal Nature ...
Peripheral cyanosis may be due to the following causes: [5] All common causes of central cyanosis; Reduced cardiac output (e.g., heart failure or hypovolemia) Cold exposure; Chronic obstructive pulmonary disease (COPD) Arterial obstruction (e.g., peripheral vascular disease, Raynaud phenomenon) Venous obstruction (e.g., deep vein thrombosis)
The most prevalent skin change is Raynaud's phenomenon, which usually appears early in the course of the disease. [14] Swollen digits are a common sign, and on occasion, the complete hand swells. [15] [16] Acrosclerosis, also known as sclerodactyly, can develop with or without proximal scleroderma and is usually a later symptom of the condition ...
One hypothesis suggests that the underlying cause may be a subtle decrease in blood flow to the optic nerve, which is enough to cause swelling of the nerve fibers but not severe enough to disrupt vision through tissue death and permanent damage to the optic nerve. When considering the possible causes for spontaneous NAION, the list includes ...
One form of the condition, known as CREST syndrome, classically results in calcium deposits, Raynaud's syndrome, esophageal problems, thickening of the skin of the fingers and toes, and areas of small, dilated blood vessels. [1] The cause is unknown, but it may be due to an abnormal immune response. [2]
