CHLOROSIS AND HYDRÆMIA.

Recent investigations show that qualitative and quantitative changes occur in the constitution of the blood of the normal pregnant woman. The red corpuscles, albumen, and iron diminish, while the white corpuscles, fibrin, and aqueous elements increase. Virchow describes this increase in the number of white corpuscles as a physiological leucocytosis dependent upon the growth of the lymph-vessels and corresponding hypertrophic changes in the pelvic and lumbar lymphatic glands. The total blood-mass is also increased—a change especially notable in the second half of pregnancy. When the number of red blood-corpuscles is abnormally diminished the woman becomes chlorotic. If, in addition, the albumen is abnormally diminished, hydræmia results. Chlorosis and hydræmia can only be regarded as independent affections in the absence of cardiac and renal lesions. They are seldom traceable to pregnancy in the absence of individual predisposition. Effusions into the subcutaneous connective tissue, pleural and peritoneal cavities, are liable to occur. Sudden exudations into the pleural cavity are particularly dangerous, while effusions into the subcutaneous tissue of the abdomen, vulva, and lower extremities are annoying and may interrupt pregnancy.

TREATMENT.—The indications for treatment are obvious. The quality of the blood must be improved, elimination of the aqueous elements attempted, and local disturbances alleviated. Nutritious food, iron in combination with non-irritant diuretics, fulfil the first two indications. Blaud's pill, which Niemeyer and Spiegelberg extol so highly, is an excellent tonic preparation. Basham's iron mixture is admirable in its effects.

PROGRESSIVE PERNICIOUS ANÆMIA.

Gusserow2 was the first to observe and describe a peculiar form of progressive pernicious anæmia occurring during gestation. The disease is of rare occurrence, and nothing is known as to its etiology. Chlorosis and hydræmia, however, may be mentioned as predisposing causes.

PATHOLOGY.—The alterations in the constitution of the blood are identical with those in anæmia and hydræmia, and produce similar effects. Evidences of fatty degeneration are found in the musculature of the heart, intima of the arteries, and portions of the capillary walls; retinal hemorrhages are constant lesions. The number of white corpuscles is not increased, and signs of leukæmia—splenic tumor, swelling of the lymphatic glands—are wanting. The condition is that of oligæmia or oligocythosis.

The prodromal symptoms occur during the first half of pregnancy, are obscure, and cannot be distinguished from the effects of chlorosis and hydræmia. After the disease has passed through its incipient stages, food, iron, and tonics seem to have no influence upon its course. During the second half of pregnancy abortion or premature labor usually occurs spontaneously. Under these conditions the shock and hemorrhage resulting from parturition are sufficient to cause a lethal issue in many cases.

PROGNOSIS.—Graefe3 has collected 25 cases of this rare affection: 1 case recovered, 2 cases were discharged improved; the others died before or shortly after labor. The prognosis is obviously grave.
