Miliaria

miliaria

Inflammatory skin disorder, with multiple small sites at sweat pores. Blockage of ducts causes sweat to escape into various levels of the skin and produce different inflammatory reactions. The most common type, known as prickly heat, results when sweat escapes into the epidermis. Pinhead blisters or pimplelike bumps occur mostly on the trunk and limbs and cause itching and burning. It mainly affects infants in tropical climates. See also perspiration, sweat gland.

Miliaria 

a condition resulting from intensified perspiration caused by overheating during hot weather or by wearing excessive clothing. The condition is observed most often in nursing infants and young children who are in poor physical condition or afflicted with such diseases as rickets, tuberculosis, or exudative diathesis. Tiny vesicles appear on the externally unchanged skin of the torso; subjective sensations are absent. Miliaria rubra (prickly heat), or itching inflamed nodules with surface vesicles, may arise. A secondary infection may develop, resulting in tiny pustules that dry into scabs. Treatment involves removal of the basic cause, good care of the skin, and observance of the rules of personal hygiene. Unctuous antiseptic powders should be applied locally.
