The inflammation starts simultaneously from numerous points, from the hair-follicles, sweat-glands or sebaceous glands. The inflammatory centres break down, and the pus finds its way to the surface; finally the process ends in gangrene of the whole area.
How would you distinguish carbuncle from a boil?
By its flat character, greater size, and multiple points of suppuration.
What is the prognosis of carbuncle?
Occurring in those greatly debilitated or in late life, and in those cases in which two or more lesions exist, or when seated about the head, the prognosis is always to be guarded, as a fatal result is not uncommon. In fact, in every instance the disease is to be considered of possible serious import.
What constitutional treatment is usually employed in carbuncle?
A full nutritious diet, the use of such remedies as iron, quinia, nux vomica, with malt and stimulants, if indicated. Calx sulphurata, one-tenth to one-fourth grain every two or three hours, appears, in some instances, to have a beneficial effect. If the pain is severe, morphia or chloral should be given.
What external measures are employed?
In the early part of the formation, injection of a five or ten per cent. carbolic acid solution, or covering the whole area with a twenty-five per cent. ichthyol ointment, may be employed. When it has broken down the pus may be drawn out with a cupping-glass, and carbolized glycerine or carbolized water introduced into each opening, and the ichthyol ointment superimposed. If the whole part has sloughed, it should be removed as rapidly as possible, and antiseptic dressings used. Or, if its progress is slow, and grave systemic disturbance be present, the whole part may be incised and curetted, and then treated antiseptically. Mild exposure to the x-rays is also to be commended.
