Cholinergic urticaria may significantly impair quality of life, especially in relation to normal day to day activities. It is caused by an overreaction of the immune system to the release of histamine, mast cells, and other chemicals in response to the small nerve fibers throughout the body due to the increase in body temperature being allergic ...
Most researchers believe this condition is actually skin sensitivity to additives in the water, such as chlorine. Water urticaria is diagnosed by dabbing tap water and distilled water to the skin and observing the gradual response. Aquagenic urticaria is treated with capsaicin (Zostrix) administered to the chafed skin.
Cholinergic urticaria (CU) is one of the physical urticaria (hives) which is provoked during sweating events such as exercise, bathing, staying in a heated environment, or emotional stress. The hives produced are typically smaller than classic hives and are generally shorter-lasting.
Cholinergic urticaria or sharp pain over the entire body induced by elevated body temperature was reported in 32 cases (50%). Of 28 cases tested, 12 (43%) displayed elevated serum IgE levels. Skin biopsy was performed in 53 cases, with normal findings in 20 cases (38%), and cellular infiltrates in sweat glands or ducts in 23 cases (43%).
Plus, new research is finding that low rep ranges (1 to 5 reps), typically associated with training power, can still help you build muscle. Win-win, if you ask us. Win-win, if you ask us. Race ...
The report also called on technology companies to be more transparent about data that can help researchers understand the impact of technology on social cohesion. It also encouraged tech companies ...
Researchers believe this is happening because hair follicle stem cells (HFSCs) required for hair growth cannot handle the oxidative stress caused by the body switching from using glucose to fat ...
However, the understanding of urticaria as an autoimmune condition is a relatively recent development in medical history. [14] The term autoimmune urticaria refers to a subset of chronic spontaneous urticaria (CSU) cases where the immune system appears to play a significant role. This understanding began to evolve in the mid to late 20th ...
