#State the diagnostic features of pompholyx.#

The distribution and the peculiar characters and course of the eruption.

It is to be differentiated from eczema.

#What is the prognosis?#

For the immediate attack, favorable, recovery taking place in several
weeks or a few months. Recurrences at irregular intervals are not
uncommon.

#What is the treatment of pompholyx?#

The general health is to be looked after, and the patient placed under
good hygienic conditions. Remedies of a tonic nature, directed
especially toward improving the state of the nervous system, are to be
prescribed. _Locally_, soothing and anodyne applications, such as
lead-water and laudanum, boric-acid lotion, oxide-of-zinc, boric-acid
and diachylon ointments, are most suitable; or the parts may be
enveloped with the following:--

[Rx] Pulv. ac. salicylici, ................ gr. x
Pulv. ac. borici,
Pulv. amyli, .......... [=a][=a] ..... [dram]ij
Petrolati, ........................... [dram]iv. M.

In fact, the external treatment is similar to that employed in acute
eczema.

#Herpes Simplex.#
(_Synonym:_ Fever Blisters.)

#What is herpes simplex?#

An acute inflammatory disease, characterized by the formation of
pin-head to pea-sized vesicles, arranged in groups, and occurring for
the most part about the face and genitalia.

#Describe the symptoms of herpes simplex.#

In severe cases, malaise and pyrexia may precede the eruption, but
usually it appears without any precursory or constitutional symptoms. A
feeling of heat and burning in the parts is often complained of. The
vesicles, which are commonly pin-head in size, are usually upon a
hyperaemic or inflammatory base, and tend to occur in groups or clusters.
Their contents are usually clear, subsequently becoming more or less
milky or puriform. There is no tendency to spontaneous rupture, but
should they be broken a superficial excoriation results. In a short time
they dry to crusts which soon fall off, leaving no permanent trace.

#Is the eruption in herpes simplex abundant?#

No. As a rule not more than one or two clusters or groups are observed.

#Upon what parts does the eruption occur?#

Usually about the face (_herpes facialis_), and most frequently about
the lips (_herpes labialis_); on the
