scalp it is always a stubborn
affection, and, as a rule, requires several months to a year of
energetic treatment to effect a cure. In this latter region the disease
will disappear spontaneously as the age of fifteen or sixteen is
reached. Tinea sycosis yields in most instances in the course of several
weeks or a few months.

#Is ringworm of these several parts treated with the same remedies?#

As a rule, yes; but the strength must be modified. The scalp will stand
strong applications, as will likewise the bearded region; upon non-hairy
portions the remedies should be used somewhat weaker. They should be
applied twice daily; ointments, if used, being well rubbed in, and
lotions thoroughly dabbed on.

#How would you treat ringworm of the general surface?#

By applications of the milder parasiticides, such as a ten to fifteen
per cent. solution of sodium hyposulphite; carbolic acid, five to thirty
grains to the ounce of water, or lard; a saturated solution of boric
acid; ointments of tar, sulphur and mercury, official strength or
weakened with lard; and tincture of iodine, pure or diluted.

When occurring upon the upper and inner part of the thighs (so-called
eczema marginatum), the same remedies are to be employed, but usually
stronger. Deserving of special mention is a lotion of corrosive
sublimate, one to four grains to the ounce; or the same remedy, in the
same proportion, may be used in tincture of myrrh or benzoin, and
painted on the parts.

#How would you treat ringworm of the scalp?#

By occasional soap-and-hot-water washing; by extraction of the involved
hairs, when practicable; by carbolic acid or boric acid lotions to the
whole scalp, so as to limit, as much as possible, the spread of the
disease; and by daily (or twice daily) applications to the patches and
involved areas of a parasiticide. The following are the most valuable:
the oleate of mercury, with lard or lanolin, in varying strength, from
ten to twenty per cent.; carbolic acid, with one to three or more parts
of glycerine or oil; corrosive sublimate, in solution in alcohol and
water, one to four grains to the ounce; sulphur ointment; and citrine
ointment, with one or two parts of lard. Chrysarobin is a valuable
remedy, but is to be employed with care; it may be prescribed as a
rubber plaster, or in a solution of gutta-percha, or as an ointment, ten
to fifteen per cent. strength. [beta]-naphthol in ointment form, five
to fifteen per cent.
