Erythema ab igne (Latin for 'redness from fire') EAI, also known as hot water bottle rash, [2] is a skin condition caused by long-term exposure to heat (infrared radiation). [3] Prolonged thermal radiation exposure to the skin can lead to the development of reticulated erythema , hyperpigmentation , scaling, and telangiectasias in the affected ...
Miliaria, commonly known as heat rash, sweat rash, or prickly heat, [1] is a skin disease marked by small, itchy rashes due to sweat trapped under the skin by clogged sweat-gland ducts. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer. [ 2 ]
The rash may appear reddish, tan, or brown, with flaking, rippling, peeling, iridescence, or cracking skin. [14] If the person is hairy, hair follicles can become inflamed resulting in some bumps (papules, nodules and pustules) within the plaque. The plaque may reach the scrotum in men and the labia majora and mons pubis in women.
Non-pharmacological treatment: In the absence of sweat, cold-water sprays and wet towels can be used to increase the evaporative loss of heat from the skin. Shifting to a cooler or air-conditioned environments when necessary can also reduce discomfort.
Cold urticaria (essentially meaning cold hives) is a disorder in which large red welts called hives (urticaria) form on the skin after exposure to a cold stimulus. [1] The hives are usually itchy and often the hands, feet and other parts of the body will become itchy and swollen as well.
Topical treatments may be used to reduce inflammation and the painful or itchy sensation or flare-ups locally at the site on the skin. Topical treatments are typically safe for the geriatric population. [12] [13] Topical treatments may include: corticosteroids; immunomodulators; menthol; local anesthetics
There are documented cases using both conservative and invasive treatments, including skin grafting and/or the application of nonadhesive dressing alongside topical corticosteroids to reduce inflammation. However, the use of steroids may exacerbate fungal infections if the aerosol product used is an antifungal medicine.
Erythema nodosum (EN) is an inflammatory condition characterized by inflammation of subcutaneous fat tissue, resulting in painful red/blue lumps or nodules that are usually seen symmetrically on both shins, on the thighs, arms, and elsewhere. [1] It can be caused by a variety of conditions but 20 to 50% of cases are idiopathic.
