The PROGNOSIS is in the highest degree unfavorable, and in those cases, few, indeed, in number, in which there were symptoms like leukæmia and which disappeared under treatment, the doubt remains whether they were true examples of the disease. When once established, the spleen and glands enlarged, the hemorrhages and dropsies present, and the blood condition marked, death is the only termination to be expected. Specially unfavorable signs are a tendency to hemorrhage, persistent diarrhoea, early dropsy, rapid increase in the splenic tumor, great excess of colorless corpuscles, and high fever. Temporary improvement may occur for weeks or even months, and the white blood-corpuscles reduce in number, but such breaks are usually transient.

TREATMENT.—If, as some writers hold, chronic malarial poisoning is an important factor in the induction of leukæmia, we should take special pains with patients so affected, and endeavor by the use of quinine and arsenic to free the system and reduce the volume of the spleen. There certainly may be danger of the development of leukæmia in any case of chronic splenic tumor, though my own experience has been that in these cases the production of anæmia of high grade, without increase in the white blood-corpuscles, is more common. It is a mistake to suppose that anæmia always accompanies chronic splenic enlargement: it may persist for years with a percentage of red corpuscles little if at all below normal, but grave anæmia or leukæmia are probabilities to be dreaded.

In an early stage, when the spleen is moderately enlarged, the lymph-glands scarcely swollen, and the leucocytosis not intense, there is a hope that by the persistent use of quinine, iron, and arsenic a cure may be effected; but when the disease is fully established and the leukæmia marked, a recovery is rarely if ever witnessed, and the treatment is largely palliative and symptomatic. To reduce the volume of the spleen various remedies are recommended, and so long as the organ is only moderately enlarged and hardened some of them may be beneficial. Quinine should be given a full and prolonged trial, as undoubtedly under its use the organ may reduce in size. As anæmia is almost always present, iron may be administered at the same time. That the quinine has any special influence over the production of the white corpuscles, as some think, I have not been able to satisfy myself. To be of use, it must be employed early and in large doses. Ergotin internally and by injection into the spleen has been recommended. I have not seen any permanent benefit from its use. Local measures, such as inunction of biniodide of mercury ointment over the spleen, the interrupted voltaic current, the application of cold, either ice or the cold douche, may be employed. Moderate reduction in the volume may be effected by these means—most effectually by the electricity and mercurial inunction.

Arsenic should always be given a trial, and pushed for several months in increasing doses. Several cases are reported in which the improvement lasted for many months. Direct injections into the spleen are also of service. Phosphorus, from which much was expected after the favorable reports of Broadbent and Wilson Fox, has not proved of much value. There are very curious remissions in the course of the disease which render therapeutical deductions somewhat fallacious. I have seen the most marked improvement occur without any special treatment: ascites and dyspnoea disappear, the white corpuscles decrease in number, and the patient from a bed-ridden, wretched condition get up, attend to light duties, and walk half a mile to hospital (Case IX.). In Case VIII. there were also during eighteen months remarkable variations, depending more on the state of the gastro-intestinal canal than the blood condition.

Transfusion has proved useless. Leukæmic blood to the amount of several ounces has been withdrawn and other healthy blood substituted.

Excision of the spleen has been frequently practised in leukæmia. Collier146 gives a résumé of 16 cases, and concludes that it is a useless and unjustifiable operation, as all of them proved fatal. A successful case, however, is reported from Italy. If performed early, there is a possibility of success, but when the organ is enormously enlarged and the blood intensely leukæmic, the conditions are most unfavorable.

Gastric symptoms and diarrhoea call for careful treatment, as the comfort of the patient depends largely on the condition of the primæ viæ. Hemorrhage is frequent, and is a dangerous symptom, particularly when it depends upon engorgement of the portal system, and calls for appropriate remedies. Purgatives are to be employed with caution. The dragging pain in the left hypochondrium, and the sense of weight and distension after eating, are very distressing, and the splenic pain may require sedatives. Inhalations of oxygen relieve the dyspnoea and have been found to check the progress of the disease.
