d Finsen light plans have, in a
measure, supplanted the previous methods of treatment. They are slow,
however, and might be, especially the _x_-ray, more satisfactorily
employed as a supplementary measure.

#Ainhum.#

#Describe ainhum.#

Ainhum is a disease of the African race, met with chiefly in Brazil, the
West Indies, and Africa, and consists of a slow but gradual linear
strangulation of one or more of the toes, especially the smallest,
resulting, eventually, in spontaneous amputation. The affected toes
themselves undergo fatty degeneration, often with increase in size, and
are, when strangulation is well advanced, considerably misshapen. The
nature of the disease is obscure.

_Treatment_ consists, in the early stages, of incision through the
constricting band; when the disease is well advanced, amputation is the
sole recourse.

#Mycetoma.#
(_Synonyms:_ Fungous Foot of India; Madura Foot; Podelcoma.)

#Decribe mycetoma.#

It is a disease involving usually the foot, and is met with chiefly in
India. It is characterized by swelling and the formation of tubercular
or nodular lesions which break down and form the external openings of
sinuses which lead to the interior of the affected part. These
discharge, and are studded with, whitish granules or black, roe-like
masses, mixed with a sanious or sero-purulent fluid. The whole part is
gradually disintegrated, the process lasting indefinitely. Its nature is
obscure; it is thought to be due to a fungus.

_Treatment_ consists in the early stages, when the disease is limited,
of thorough curetting and cauterization; later, after the part is more
or less involved, amputation, at a point well up beyond the disease,
becomes necessary. Potassium iodide internally may exert a favorable
influence.

#Perforating Ulcer of the Foot.#

#Describe perforating ulcer of the foot.#

Perforating ulcer of the foot is a rare disease, consisting of an
indolent and usually painless sinus leading down to diseased bone. The
external opening, which is through the centre of a corn-like formation,
is small, and may or may not show the presence of granulations. The
affected part is commonly more or less anaesthetic and of subnormal
temperature. One or several may be present, either on one or both feet.
The most common site is over the articulation of the metatarsal bone
with the phala
