Erythema Nodosum

This is a much more important but also rarer affection than the preceding one. The disease is characterized by the eruption of reddish tumors, from the size of a bean to that of a small egg, and usually situated upon the lower extremities, between the knee and ankle. For a day or two the depth of color increases, then becomes somewhat purplish, and with the "black-and-blue" appearance which ac­companies hemorrhagic effusions, and finally passes into the stage of green and yellow, like an ordinary bruise. A week or ten days may be occupied by these processes; and, as the color changes, diminution of size takes place, and in about two weeks complete resolution is effected. Suppuration very rarely occurs. The number of the nodes is usually limited to three or four, but may reach nine or ten, and may appear on the thighs and upper extremities as well as the parts already named. The swellings are usually a little painful for the first day or two, but not afterward. Relapies may prolong the disease for several months. Occasionally the eruption is ushered in by febrile action, but not In all cases. It usually occurs in young females, and is not unfrequently accompanied by menstrual derangement. In many cases, however, the eruption is preceded by or complicated with arthritic pains. This has led many writers to believe the affection to be more or less closely connect­ed with rheumatism.

Tht: disease is self-limited, requiring no special treatment Other than sedative applications to the affected parts.

In erythema multiforme the allopaths claim that "Unless the cause of the affection be discovered, little need or can be dene in the way of treatment, and the affection may be left to run its course, which it will usually do in two or three weeks, and may not return until the following season, for in some persons this disease appears to affect a predilection for the spring and autumn months, returning annually at one or the other of these seasons."

Treatment
When there is much itching and burning either a carbolic acid or veratrum viride lotion may he used. When the opposing surfaces are much inflamed they may be protected by dusting with buckwheat powder, or equal parts of starch and zinc oxide. Especial attention should be paid to cleanliness, and all irritants should be removed. Poultices are apt to do more harm than good, and better be avoided. Particular attention must be paid to the diet; such food as cornflour, maizena, and the like must be forbidden, and proper nutritive substitutes be given to children in conjunction with a suitable quantity of milk.

In the erythemata dependent upon general causes you must always remember the effect of ingesta; that a gouty or rheumatic habit, disordered menstrual function, dentition, delicacy of skin, or lymphatic temperament, are present in greater or less degree. It is important to allow the patient the use of an unstimulating diet only, to forbid him spirits, wine, and beer, to clear out the bowels, and in the early stage to adopt a soothing regime, with tepid sponging and emollient baths.


Bed-sores are best treated by attempting io "harden" the skin in the early stage by spirit applications, removing pressure as much as possible at later stages by pads, cushions, and water-beds, and by using charcoal poultices or soap plaster spread on soft leather to the sores. For chilblains, equal parts of turpentine and tincture of Aconite, and soap liniment, together with the indicated re­medy, constitute the best treatment.

Mr. M., a very large and fleshy man of exceedingly good habits and with no history of specific trouble, presented himself for a long standing and obstinate erythema. The case had been prescribed for under nearly every conceivable diagnosis, the majority of physicians claiming it was due to syphilis. During a fishing expedition, some years ago, he thought he had been poisoned while in bathing, and since that time he has been exceedingly troubled with this persistent local inflammation. His unusual flesh had been a constant irritant, and being obliged to work for his living he had almost despaired of recovery.


In the folds of his right groin and extending back between the nates an immense phlegmonous surface was visible. So long had it existed that fissures and ulcerations, and excessive secretions of sweat and pus had complicated what might have been a short enduring, and simple sore. A. rash, like measles, extended over the surrounding healthy skin. Extreme local itching and general aching pains made him exceedingly restless. These symptoms were always worse after midnight and during wet or cold weather.

With these indications he was given Rhus tox. 30 four times daily for a week. He was directed to use a local wash of warm water and lanoline soap, being careful to wipe the parts to perfect dryness. He was then to use a dusting powder of aristol and wear an abdominal sup­porter to relieve any chafing. In four weeks he was entirely well.
