Miliaria

Miliaria is an acute dermatitis that occurs most commonly on the trunk and intertriginous areas. A hot, moist environment is the most frequent cause. Bedridden febrile patients are susceptible. Plugging of the ostia of sweat ducts occurs, with consequent ballooning and ultimate rupture of the sweat duct, producing an irritating, stinging reaction. Increase in numbers of resident aerobes, notably cocci, apparently plays a role.

Symptom of Acne vulgaris

The usual symptoms are burning and itching. In severe cases, fever, heat prostration, and even death may result. The lesions consist of small, superficial, red, thin-walled, discrete but closely aggregated vesicles (miliaria crystallina), papules (miliaria rubra), or vesicopustules or pustules (miliaria pustulosa). The reaction occurs most commonly on covered areas of the skin.

Treatment of Acne vulgaris

Triamcinolone acetonide, 0.1% in Sarna lotion, or a mid-potency corticosteroid in a lotion or cream—but not ointment—base, should be applied two to four times daily. Secondary infections (superficial pyoderma) are treated with dicloxacillin, 250 mg four times daily by mouth. Anticholinergic drugs given by mouth may be helpful in severe cases, eg, glycopyrrolate, 1 mg twice daily.
