The peculiar appearance, the course and character of the patches, of morph[oe]a are quite distinctive. #Give the prognosis of scleroderma.# It should always be guarded. In many instances recovery takes place, whilst in others the disease is rebellious, lasting indefinitely. The prognosis of the variety known as morph[oe]a is less unfavorable than general scleroderma, and recovery more frequent. #What is the treatment of scleroderma?# Tonics, such as arsenic, quinia, nux vomica, and cod-liver oil; conjointly with the local employment of stimulating, oily or fatty applications, friction, and electricity. Roentgen-ray treatment is often of value, more especially in the morph[oe]a type. #Elephantiasis.# (_Synonyms:_ Elephantiasis Arabum; Pachydermia; Barbadoes Leg; Elephant Leg.) #Give a descriptive definition of elephantiasis.# Elephantiasis is a chronic hypertrophic disease of the skin and subcutaneous tissue characterized by enlargement and deformity, lymphangitis, swelling, [oe]dema, thickening, induration, pigmentation, and more or less papillary growth. [Illustration: Fig. 35. Elephantiasis of moderate development.] #What parts are commonly involved in elephantiasis?# Usually one or both legs; occasionally the genitalia; other parts are seldom affected. #Describe the symptoms of elephantiasis.# The disease usually begins with recurrent (at intervals of months or years) erysipelatous inflammation, with swelling, pain, heat, redness and lymphangitis; after each attack the parts remain somewhat increased in size, although at first not noticeably so. After months or one or two years the enlargement or hypertrophy becomes conspicuous, the part is chronically swollen, [oe]dematous and hard; the skin is thickened, the normal lines and folds exaggerated, the papillae enlarged and prominent, and with more or less fissuring and pigmentation. #What is the further course of the disease?# There is gradual increase in size, the parts in some instances reaching enormous proportions; the skin becomes rough and warty, eczematous inflammation is often superadded, and, sooner or later, ulcers, superficial or deep, form--which, together with the crusting and moderate scaliness, present a striking picture. There may be periods of comparative inactivity, or, after reaching a certain development, the disease may, for a time at least, remain stationary. #Are there any subjective symptoms?# A variable degree of pain is often noted, especially marked during the inflammatory attacks. The general health is not involved. #State the cause of elephantiasis.#
