866 Eczema. 



mind the possibility of an intoxication, only small surfaces 

 should be treated at one time. In order to avoid phenol pois- 

 oning Glauber's salts may be given in small doses internally. 

 Creolin and lysol are effective and applied in the same form as 

 tar. Still creolin should be used with caution, as contrary to the 

 experience of Frohner, the authors have often seen poisoning 

 after its employment. In this stage good effects are also pro- 

 duced by naphthol and naphthaline (5 to 15% ointment [both 

 of little use for the horse on account of danger from poison- 

 ing]), glycerinated iodine (1 part tincture of iodine and 4 parts 

 glycerine), resorcin, salicylic acid (5 to 15% ointment), especial- 

 ly in marked thickenings of the horny layer or in seborrheic 

 eczema. All these remedies cause a separation of the horny 

 layer, lessen the itching and promote the absorption of the exu- 

 date from the tissue of the cutis. In obstinate chronic eczema 

 of the horse with cracking of the skin, Eoder saw good effects 

 from sulphur and mercury ointment with the addition of can- 

 tharides, while Sehindelka often obtained very good results in 

 chronic seborrheic eczema of dogs by using sulphur baths and 

 bran baths w^ith the addition of sulphurated potash. In chronic 

 greasy heel of the horse, Storcli found lead nitrate efficacious 

 when he used it after removing the granulomas from the 

 cleansed skin, pressing it down with the finger in a layer as 

 thick as the back of a knife blade and securing it with a bandage 

 that w^as changed 3 or 4 times daily. Sommer healed very severe 

 cases of eczema of the fetlock with Dealin (a combination of 

 oxygen and fatty substances) in x)owder form. 



If the disease process is already considerably improved and 

 only few scales desquamate from the skin, which has regained 

 its softness and elasticity, then the process of desquamation is 

 hastened by rubbing in of bland remedies (olive oil, ungu. 

 simplex). Any itching that may still be present at this stage 

 may be controlled by nafalan, naftalan or sapolan. 



In every kind of eczema internal treatment requires full 

 consideration, especially if at the same time symptoms are pres- 

 ent pointing to a disease of the digestive organs. In this con- 

 nection the disinfection of the digestive canal or the employ- 

 ment of mild purgatives is proper. Thus Sehindelka obtained 

 good results in many cases in dogs through internal medicines 

 (1.0 gm. of cinnamon powder, 1.5 gm. eucalyptol, 30 drops of 

 oil of peppermint: 1.5-5 gm. daily in five doses). Arsenical 

 preparations have always been ascribed a favorable influence 

 (of Fowler's solution a tablespoonful for horses, 5 to 10 drops 

 a day for dogs). This good influence is confirmed by recent 

 o])servations. Paron and Urechie among others saw recovery 

 occur in man after the internal use of calcium chlorate (3 gm. 

 daily) in solution; improvement commenced the next day, and 

 in five days the itching had disappeared. Care must be taken 

 to secure the suitable feeding of the animal with non4rritating 

 and easily digested food stuffs.
