Description, Causes and Risk Factors:
Alternative Name: Miliary fever, sweat rash, prickly heat.
Types may include:
In normal conditions, the skin functions as body temperature adjustment with environmental temperature. In the skin, the function of sweat glands (the coil glands of the skin that secrete the sweat to enable evaporative cooling in a hot environment or in response to emotion) help the body to adjust the temperature. Miliaria is a bumpy rash cause when sweat glands in the skin are blocked. Miliaria looks like tiny bumps surrounded by a zone of red skin. It usually occurs on clothed parts of the body, such as the back, abdomen, neck, upper chest, groin, or armpits. Although it affects people of all ages, it is especially common in children and infants due to their underdeveloped sweat glands.
Miliaria begins with excessive perspiration usually in a hot, humid environment. The perspiration damages cells on the surface of the skin forming a barrier and trapping sweat beneath the skin, where it builds up causing the characteristic bumps. As the bumps burst and sweat is released, you may feel the prickly, or stinging.
Factors that influence the occurrence of miliaria may include:
A lack of good air ventilation.
Too thick and tight clothes.
High humidity allows your body sweat.
Symptoms of miliaria include small red rashes, called papules, which may itch or more often cause an intense ''pins-and-needles'' prickling sensation.Your child may feel fatigued and become irritable and intolerant of heat, due to little or no sweating at the affected areas.
Differential diagnosis may include:
Erythema toxicum neonatorum.
Miliaria is typically diagnosed based on the characteristic appearance of the affected area. Other testing is not generally required.
In most cases, the heat rash goes away on its own, without any medication. However, some severe forms of the rash may need to be treated with medication. The use of Calamine lotion and other topically applied steroids can help prevent the rash from recurring. The best way to relieve the heat rash symptoms and prevent it from occurring again by keeping the skin clean, cool and dry at all times. Prickly heat powders, using antibacterial agents and ingredients menthol and camphor with mild analgesic and cooling properties, can be applied to the affected areas to relieve the itching and discomfort.
Remove any occlusive clothing, limit activity, and seek air conditioning or any cooler environment.
Cool compresses can also help with the discomfort of heat rash.
Make sure your child is drinking lots of fluids.
Prevention and treatment of miliaria consist of controlling heat and humidity.
