Raynaud's Disease is a rare disorder that affects the arteries. Arteries are blood vessels that carry blood from your heart to different parts of your body. Raynaud's is sometimes called a disease, syndrome, or phenomenon. The disorder is marked by brief episodes of vasospasm (narrowing of the blood vessels). Vasospasm of the arteries reduces blood flow to the fingers and toes. In people who have Raynaud's, the disorder usually affects the fingers. In about 40 percent of people who have Raynaud's, it affects the toes. Rarely, the disorder affects the nose, ears, nipples, and lips.
Children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems, a UC Davis Health study has found.
The arctic cold snap affecting the Midwest and the Northeast this weekend should not be taken lightly, says David Holmes, MD, clinical associate professor of family medicine in the University at Buffalo School of Medicine and Biomedical Sciences.
Vibration-induced white finger disease (VWF) is caused by continued use of vibrating hand held machinery (high frequency vibration >50 Hz), and affects tens of thousands of people. New research published in BioMed Central's open access journal Clinical Epigenetics finds that people with a genetic polymorphism (A2191G) in sirtuin1 (SIRT1), a protein involved in the regulation of endothelial NOS (eNOS), are more likely to suffer from vibration-induced white finger disease.
Cold feet-those chilly appendages that plague many people in the winter and an unlucky few all year round-can be the bane of existence for singles and couples alike. In a new study, scientists led by Selvi C. Jeyaraj of the Research Institute at Nationwide Children's Hospital have identified a biological mechanism that may be responsible for icy extremities: an interaction between a series of molecules and receptors on smooth muscle cells that line the skin's tiny blood vessels.
A "genetic accelerator" is responsible for the most severe cases of Lupus (systemic lupus erythemathosus), an autoimmune disease: the accelerator, called enhancer HS1.2, speeds up the activity of some critical genes of the immune system involved in the disease.
Systemic scleroderma has slowed Tracy Zinn but it has not stopped her from working. Thanks in part to determination and an accommodating employer, Zinn is now in her 13th year as an account executive for a firm that produces educational software. But, many with the incapacitating disease are not as fortunate.
Cold weather triggers a painful and sometimes debilitating disorder for millions of Americans who suffer from Raynaud's disease (also known as Raynaud's syndrome or phenomenon). Raynaud's is an autoimmune disorder in which spasms in the blood vessels can interrupt blood flow to the fingers, toes, nose and ears. Exposure to cold triggers the spasms, typically causing the affected area to turn white, then blue, then bright red. Emotional stress can also cause an attack.
There's a medical reason behind cold fingers and toes, when a chill seems to instantly turn extremities white.
German researchers have discovered yet another use for Viagra (sildenafil), they say it relieves the symptoms and improves the circulation of patients with Raynaud's phenomenon.
