Hyperalgesia (/ ˌ h aɪ p ər æ l ˈ dʒ iː z i ə / or /-s i ə /; hyper from Greek ὑπέρ (huper) 'over' + -algesia from Greek ἄλγος (algos) 'pain') is an abnormally increased sensitivity to pain, which may be caused by damage to nociceptors or peripheral nerves and can cause hypersensitivity to stimulus.
Loeffler's and the latter cases had pathological features of eosinophil infiltrations not only into the heart's myocardium but also its epicardium (i.e. lining of the heart chambers). Although eosinophilic myocarditis due to other underlying causes may show little or no eosinophil infiltrations into the endocardium, Loeffler endocarditis is ...
Allergic ACS is a syndrome involving two components. One component is immune-mediated resulting in hypersensitivity, allergy, and an anaphylactic or anaphylactoid reaction. The second component involves cardiac signs and symptoms seen with acute coronary syndrome (ACS). Cardiac symptoms vary depending on the type of variant the patient presents ...
Underlying structural valve disease is usually present in patients before developing subacute endocarditis, and is less likely to lead to septic emboli than is acute endocarditis, but subacute endocarditis has a relatively slow process of infection and, if left untreated, can worsen for up to one year before it is fatal.
Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory hyperesthesia". In the context of pain, hyperaesthesia can refer to an increase in sensitivity where there is both allodynia and hyperalgesia .
The original 2009 Lake Louise Criteria had a 74% sensitivity and 86% specificity in the diagnosis of myocarditis, but when adding the 2018 update to the criteria (in which T1 signal intensity was found to have high diagnostic sensitivity), the sensitivity and specificity in the diagnosis of myocarditis increased to 88% and 96% respectively.
Hypersensitivity (also called hypersensitivity reaction or intolerance) is an abnormal physiological condition in which there is an undesirable and adverse immune response to an antigen. [ 1 ] [ 2 ] It is an abnormality in the immune system that causes immune diseases including allergies and autoimmunity .
Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone. [4] [5] OIH is not necessarily confined to the original affected site. [6]
