e discontinued for a few
days and soothing applications made. Resorcin, in lotion, 3 to 25 per
cent strength, is through the exfoliation it provokes, frequently of
value; the resorcin paste referred to in acne can also be used for this
purpose.

Moderately strong applications of the Faradic current, repeated once or
twice weekly, are sometimes of service; also weak to moderately strong
applications of the continuous and high-frequency currents. Roentgen-ray
treatment can also be resorted to in extremely obstinate cases.

In occasional instances sulphur preparations not only fail to do good,
but materially aggravate the condition. In such cases, if resorcin
preparations also fail, the mercurial lotion and ointment employed in
acne may be prescribed. Mercurial and sulphur applications should not be
used, it need scarcely be said, within a week or ten days of each other,
otherwise an increase in the comedones and a slight darkening of the
skin result from the formation of the black sulphuret of mercury.

#Milium.#
(_Synonyms:_ Grutum; Strophulus Albidus.)

#What is milium?#

Milium consists in the formation of small, whitish or yellowish,
rounded, pearly, non-inflammatory elevations situated in the upper part
of the corium.

#Describe the clinical appearances.#

The lesions are usually pin-head in size, whitish or yellowish,
seemingly more or less translucent, rounded or acuminated, without
aperture or duct, are superficially seated in the skin, and project
slightly above the surface.

They appear about the face, especially about the eyelids; they may occur
also, although rarely, upon other parts. But one or several may be
present, or they may exist in numbers.

#What is the course of milium?#

The lesions develop slowly, and may then remain stationary for years.
Their presence gives rise to no disturbance, and, unless they are large
in size or exist in numbers, causes but slight disfigurement.

In rare instances they may undergo calcareous metamorphosis,
constituting the so-called _cutaneous calculi_.

#What is the anatomical seat of milium?#

The sebaceous gland (probably one or several of the
superficially-situated acini), the duct of which is in some manner
obliterated, the sebaceous matter collects, becomes inspissated and
calcareous, forming the pin-head lesion. The epidermis is the external
covering.
