Cure For Prickly Heat( Miliaria)
Miliaria (miliaria rubra, sweat rash or prickly heat) is a skin disease marked
by small and itchy rashes. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season. Although it affects people of all ages, it is especially common in children and infants due to their underdeveloped sweat glands.
Pathology
Miliaria (Prickly Heat) occurs when the sweat gland ducts get plugged due to dead skin cells or bacteria such as Staphylococcus epidermidis, a common bacterium that occurs on the skin which is also associated with acne. The trapped sweat leads to irritation (prickling), itching and to a rash of very small blisters, usually in a localised area of the skin.
Clinical features
Symptoms of miliaria include small red rashes, called papules, which may itch or more often cause an intense ''pins-and-needles'' prickling sensation. These rashes may simultaneously occur at a number of areas on a sufferer''s body, the most common including the face, neck, under the breasts and under the scrotum. Other areas include skin folds, areas of the body that may rub against clothing, such as the back, chest, and stomach, etc. A related and sometimes simultaneous condition is folliculitis, where hair follicles become plugged with foreign matter, resulting in inflammation.
Other types of miliaria
In a similar mild condition called miliaria crystallina, instead of small rashes, there are tiny blisters that look like beads of perspiration. miliaria profunda, sometimes referred to as Wildfire due to the rapid spread and severe burning sensations, is a severe form of miliaria caused by a complication due to repeated outbreaks of miliaria rubra, the sweat ducts are completely blocked. This inability to sweat may cause the patient to be prone to heat exhaustion. Once triggered, a severe attack of miliaria commonly lasts 5-6 weeks because the plugs which form in the sweat duct openings can only be cast off by the outward growth of the sweat duct cells.The most severe forms of prickly heat have very similar symptoms to severe burns. The term Wildfire is used because the generation of excess heat and the inability to expel the heat can lead to a cascade effect where the trapped sweat causes blisters to break, the immune system, adrenal system, and patient psychological response to the pain and panic response to the rapidly spreading rash causes additional biological activities and heat and the entire system cascades (or breaks down).
Prevention
Prickly heat can be prevented by avoiding activities that induce sweating, using air conditioning to cool the environment, wearing light clothing and in general, avoiding hot and humid weather. If that is not possible, and especially if air conditioning is unavailable or unaffordable, then taking multiple showers throughout the day (and night as well if needed) to unplug and clean the sweat glands is the best defense against it.
Treatment
There is currently little in the way of specific medical treatment, but in most cases the rashes disappear by themselves. Severe infections can last weeks. Early and continuous treatment of minor infections can effect recovery within a matter of days. Staying in an air-conditioned environment to avoid sweating will speed-up the healing process and lessen symptoms. Anti-itch lotions, such as calamine and topical steroid creams can be used to sooth and control the itching. Use caution however as anything which blocks the release of sweat and heat and in particular oil based products block the glands and slow the defoliation process and should be avoided. Antibiotics and topical antiseptics are used to prevent bacterial blooms, reducing the chances of the sweat glands being plugged and causing inflammations. In some cases, vitamin A and C supplements can help shorten the duration and severity of the symptoms. Prickly heat powders, using antibacterial agents and ingredients enthol and camphor with mild analgesic and cooling properties, can be applied to the affected areas to relieve the itching and discomfort. Healing takes time even when bacteria are reduced as new sweat gland cells need time to regrow as the damaged cells defoliate.In the cases where the rash has caused open blisters to form a doctor should be consulted immediately as the open sores are almost certain to infect and cause secondary problems without preventative measures.
