Q and A: about health and research

Cutaneous vasculitis is an inflammatory condition affecting the small blood vessels in the skin, often triggered by an abnormal immune response. It may occur as an isolated skin disease or as part of a broader systemic vasculitis involving internal organs. Recognizing and understanding this condition is crucial, as its manifestations can range from mild skin changes to serious tissue damage. What Are the Symptoms of Cutaneous Vasculitis? Because the skin is directly involved, cutaneous vasculitis is often visibly identifiable—if you know what to look for. Common symptoms include: Purpura : Red or purple spots caused by bleeding into the skin, which do not blanch (disappear) when pressed. Petechiae : Very small, pinpoint bleeding spots that typically start on the lower legs. Ulcerations : Painful skin ulcers that develop quickly and can progress rapidly. Necrosis : Tissue death around wounds due to disrupted blood supply. Swelling and redness : Particularly in areas where ...

This is a  collection of skeletal muscle weakness-related illnesses. β-Hydroxybutyrate Elicits Favorable Mitochondrial Changes in Skeletal Muscle   The clinical benefit of ketosis has historically and almost exclusively centered on neurological conditions, lending insight into how ketones alter mitochondrial function in neurons. However, there is a gap in our understanding of how ketones influence mitochondria within skeletal muscle cells.  https://pubmed.ncbi.nlm.nih.gov/30071599/ The ketone body β-hydroxybutyrate (BHB) is synthesized in the liver from fatty acids and represents an essential carrier of energy from the liver to peripheral tissues when the supply of glucose is too low for the body's energetic needs . https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6640868/  Post-polio syndrome and muscle weakness Post-polio syndrome (PPS) is a disorder of the nerves and muscles. It happens in some people many years after they have had polio. PPS ma...
