inflammatory areola, thus giving the whole
eruption a bright red appearance--_miliaria rubra_. Later, the areolae
fade, the transparent contents of the vesicles become somewhat opaque
and yellowish-white, and the eruption has a whitish or yellowish
cast--_miliaria alba_. In long-continued cases, especially in children,
boils and cutaneous abscesses sometimes develop; and it may also develop
into a true eczema.

Itching, or a feeling of burning, slight or intense, is usually present.

#What is the course of the eruption?#

The vesicles show no disposition to rupture, but dry up in a few days or
a week, disappearing by absorption and with slight subsequent
desquamation; the papular lesions gradually fade away, and the
affection, if the exciting cause has ceased to act, terminates.

#What is the cause of miliaria?#

Excessive heat. Debilitated individuals, especially children, are more
prone to an attack. Being too warmly clad is often causative.

#What is the nature of the disease?#

The affection is considered to be due to sweat-obstruction, with mild
inflammatory symptoms as a cause or consequence, congestion and
exudation taking place about the ducts, giving rise to papules or
vesicles, according to the intensity of the process.

#How would you distinguish miliaria from papular and vesicular eczema,
and from sudamen?#

The papules of eczema are larger, more elevated, firmer, slower in their
evolution, of longer duration, and are markedly itchy.

The vesicles of eczema are usually larger, tend to become confluent, and
also to rupture and become crusted; there is marked itchiness, and the
inflammatory action is usually severe and persistent.

In sudamen there is absence of inflammatory symptoms.

#What is the prognosis of miliaria?#

The affection, under favorable circumstances, disappears in a few days
or weeks. If the cause persists, as for instance, in infants or young
children too warmly clad, it may result in eczema.

#What is the treatment of miliaria?#

Removal of the cause, and in debilitated subjects the administration of
tonics; together with the application of cooling and astringent lotions,
as the following:--
