mmediate neighborhood of one or both nostrils is met
with, taking its origin from an inflammation of the hair-follicles just
inside the margin of the nose; constitutional symptoms are usually
wanting. Somewhat similar, doubtless, is the erysipelatous inflammation
(_erysipeloid_) observed on the fingers and hands of butchers, etc.,
starting from a wound, apparently as a result of infection from putrid
meat or fish.

#What is erysipelas migrans (or erysipelas ambulans)?#

A variety of erysipelas which, after a few hours or days, disappears at
one region and appears at another, and so continues for one or several
weeks.

#What is the cause of erysipelas?#

The disease is due to a specific streptococcus--the streptococcus of
Fehleisen. Depression of the vital forces and local abrasions are
predisposing factors.

#State the diagnostic points.#

The character of the onset, the shining redness and swelling, the
sharply-defined border, and the accompanying febrile disturbance.

#What is the prognosis in erysipelas?#

In most instances the disease runs a favorable course, terminating in
recovery in one to three weeks. Exceptionally, in severe cases, a fatal
termination ensues.

#What is the treatment of erysipelas?#

_Internally_, a purge, followed by the tincture of the chloride of iron
and quinia, and stimulants if needed. _Locally_, one to three per cent.
carbolic-acid lotion or ointment, a saturated solution of boric acid, or
a ten- to twenty-per-cent. aqueous solution or ointment of ichthyol may
be employed.

In some cases the spread of the disease is apparently controlled by
painting the bordering healthy skin with a ring of tincture of iodine or
strong solution of nitrate of silver.

#Phlegmona Diffusa.#

#What do you understand by phlegmona diffusa?#

Phlegmona diffusa is a more or less extensive inflammation of the
cutaneous and subcutaneous tissues presenting symptoms partaking of the
nature of both deep erysipelas and flat carbuncles, and usually attended
with varying constitutional disturbance. Suppuration at several points
takes place, and sloughing may ensue. Recovery usually finally results,
but a fatal issue is possible.

Treatment is based upon general principles.
