#What treatment would you prescribe for ichthyosis?#

Treatment that has in view removal of the scaliness and the maintenance
of a soft and flexible condition of the skin.

In mild cases frequent warm baths, simple or alkaline, will suffice; in
others an application of an oily or fatty substance, such as the
ordinary oils or ointments, made several hours or immediately before the
bath may be necessary. In moderately developed cases the skin is to be
washed energetically with sapo viridis and hot water, followed by a warm
bath, after which an oily or fatty application is made. In some of the
more severe cases the following plan is often useful: The parts are
first rubbed with a soapy ointment consisting of one part of
precipitated sulphur and seven parts of sapo viridis; a bath is then
taken, the skin wiped dry, and a one to five per cent. ointment of
salicylic acid gently rubbed in.

Glycerine lotions, one or two drachms to the ounce of water, are also
beneficial; as also the following:--

[Rx] Ac. salicylici, ...................... gr. x-xl
Glycerini, ........................... [dram]ss-[dram]j
Lanolin,
Petrolati, .................. [=a][=a] [Oz]ss

In severe cases of ichthyosis hystrix it may be necessary, also, to
employ caustics or the knife.

#What systemic treatment would you prescribe?#

Constitutional remedies are practically powerless; occasionally some
good is accomplished by the internal administration of linseed oil and
jaborandi.

#Describe onychauxis.#

Onychauxis, or hypertrophy of the nail, may take place in one or all
directions, and this increase may be, and often is, accompanied by
changes in shape, color, and direction of growth. One or all the nails
may share in the process. As the result of lateral deviation of growth,
the nail presses upon the surrounding tissues, producing a varying
degree of inflammation--_paronychia_.

#What is the etiology of hypertrophy of the nail?#

The condition may be either congenital or acquired. In the latter
instances it is usually the result of the extension to the matrix of
such cutaneous diseases as psoriasis and eczema; or it is produced by
constitutional maladies, such as syphilis.
