Tissue ischemia can also occur in the absence of atherosclerosis or other abnormalities of arteries. One example of a condition in which the blood vessels themselves are not damaged isRaynaud's disease, which is believed to occur due to spasms in blood vessels brought on bystressor acoldenvironme...
then a healthy AV node can do so at a rate of about 40, and if needed, the ventricles themselves can generate heartbeats at a rate of about 20 per minute. This may occur if the cells of the upper
When you have a chest pain, the first thing you should try to clarify is whether it indicates an anginal pain, or pain of cardiac ischemia (heart attack).Angina pectorispresents some typical characteristics that can be used to remove or raise the suspicion of cardiovascular disease. Anginal p...
Neoplastic and vascular disorders of the brain are further discussed in Chapter 12. Asymmetry often is associated with inflammatory, immune-mediated, neoplastic, and ischemic disorders. Diffuse and symmetric involvement is seen with degenerative, metabolic, and toxic disorders. The acute or chronic ...
Both focal and systemic ischemia cause neuronal damage detectable as a leakage of NFL into the CSF proportional to the severity of the injury [5, 7, 8]. In chronic disorders the release of NFL is less pronounced but still raised to several times normal in active degeneration of white matter...
*It is often worth clarifying with the patient the normal position of their testes in their scrotum (i.e. which testis normally sits higher) The TWIST Score The TWIST score (Testicular Workup for Ischemia and Suspected Torsion) is increasingly being used to differentiate between patients who re...
Importantly, these changes can be identified with commonly used nuclear stains and used as markers of poor perfusion-fixation. Although frozen sections are widely used, no markers are available to ensure that the observed changes were not confounded by perfusion-induced hypoxia/ischemia. Moreover, ...
What are the symptoms of passing a kidney stone? How do gallstones cause pancreatitis? What are the symptoms of myocardial ischemia? What is acute intestinal ischemia? What happens when a gallstone blocks the bile duct? Where does an abdominal aortic aneurysm occur? What cause...
(squeezed by musculature), bile usually goes out through the bile ducts into the GI tract; however, if gallstones or gallstone sludge is present, there can be partial or complete blockage of the ducts with pressure on the surrounding tissue, sometimes enough to cause local ischemia (inadequate...
