Corns are localized callosities or horny thickenings of the skin usually resulting from ill-fitting shoes. They are protective in nature. Where excessive impact, friction, or pressure has existed there usually results in an area of tenderness, a. blister or an abrasion. To remedy the existing evil and to prevent a repetition, nature causes to be formed a hard horny layer of skin which protects the particular part from further injury. If the cause continues the layers of hardened skin multiply and increases the thickness of the corn. Finally, prolongations downward into the sensitive true skin are formed and pressing on nerves cause pain. These callosities are most commonly found on the tops of the toes, between the toes, on the outer aspect of the little toe, on the ball of the foot under the anterior arch and on the margin of the heel.

The importance of this subject consists in its unusual and extreme prevalence; and disabling features which do much to reduce the marching ability of a military organization. The cause of corns is found in ill-fitting shoes worn at the time of examination or previously, To determine this is imperative because if the cause is not removed there will certainly be a recurrence of the condition. To remedy the latter, the shoes, if not suitable to adjustment, should be discarded or the shoe stretcher used in satisfactory shoes to remove friction and pressure.

It requires almost constant attention to bring relief from corns if their entire removal is not contemplated. The feet are soaked in warm water for a period of fifteen minutes and the corn pared down every week or so, care being taken not to be overzealous in cutting deep and drawing blood. When this is done measures must be taken immediately to check any infection because infections of the feet are very serious. Apply to the area from which the blood is oozing Tr. I ot..ne 3101 per cent., then alcohol and cover with adhesive or apply directly the salicylic acid-collodion. The pairing of corns is a temporary, not a permanent measure, and is not recommended. To soften the horny tissue so that the whole corn will in a short time come out and be cured permanently nothing is better than the following combination.

Flexible collodion Oz. 1 ounce

This is supplied by the medical department and is often superior to any patented remedy on the market. The claims of manufacturers of corn remedies to remove a corn in a night are false and the opportunity is here taken to inform officers of the service that such is so. The solution above given is inflammable and should not be near lighted matches, cigarettes, etc. The bottle should be kept tightly corked as evaporation is rapid when the contents are exposed to the air. The method of removing corns is as follows:

(a) Wash the foot thoroughly.

(b) Immerse in hot water about 15 minutes. When withdrawn note that the color of the corn is white and is soft to the touch.

(c) Dry the foot thoroughly.

(d) Apply the saIcylic-collodion to the corn and about one-eighth of an inch around. Allow to dry. Apply another layer. The application is made with a glass rod or wooden applicator.

(e) Apply adhesive plaster.

This should be done on an average every day for four treatments. Sometimes even four treatments do not suffice and applications must be continued. Where the upper layer of the corn is particularly hard a thin slice may be paired off so that the salicylic acid-collodion can affect the tissue. At the end of the course of treatment, it will be found that the corn has a dead white appearance. With the end of tissue forceps or the back of the blade of a knife slide it under the loose dead skin at the margin of the corn and proceed around the corn. Take care while paying the corn loose from the tissue not to cut the roots of prolongations which extend downward into the flesh because if these are severed the corn will recur. The whole treatment is directed toward removing the whole corn en masse with its roots and not piece-meal. 13leed-ing should not be caused when the corn is pulled out completely down to the derma or true skin (the quick). The treatment described is best done while the men are in barracks; and should a march be taken immediately or soon after the sensitive areas, formerly occupied by corns, may be covered with adhesive.

As callouses and corns are similar the treatment directed to remedying the former is the same as the latter. Lastly, attention should be given to the fact that the cause, ill-fitting shoes, must be removed or the condition will recur.
