=Malformation of the uterus= may possess an obstetric interest at times. The double uterus (uterus didelphys) and the uterus with a rudimentary horn (uterus bicornis) are examples. These are congenital conditions, due to imperfect development, and pregnancy may take place in one or both sides. If in one side only, the other half will also exhibit the softening and other changes as in normal cases. Binovular twins may be the result of a pregnancy in each side. =Pressure Symptoms.=—_Edema_ of legs and sometimes of the vulva occurs during the last trimester. It is due to increased intraabdominal pressure and to direct interference with the return circulation by the pressure of the heavy uterus on the iliac veins at the brim of the pelvis. The urine should be examined for albumin and the patient put in the horizontal position if the edema is troublesome. _Varicose veins_ of legs and vulva may cause much distress. The limbs should be bound with flannel spirals or with rubber bandages in the recumbent position, or elastic stockings may be obtained. Operation during pregnancy is not to be considered. The vulva can only be relieved by a double bandage, which is sewed at the point where it crosses the vulva, and buckled or tied to a waistband above the hips, both before and behind. This brings support to the vulva. If the veins rupture, the part should be elevated and compressed with an aseptic pad. _Hæmorrhoids_ may either appear or grow worse late in pregnancy. If they protrude, they should be replaced. Ointments and iced applications may be used and the bowels kept loose. _Cramps_ may occur in the muscles of the legs, due sometimes to the varicose veins and sometimes to pressure on the lumbosacral plexus. =Moles.=—Mole is the name given to an ovum which is destroyed by disease of its coverings during the early months of gestation. Two kinds are known, the blood mole (carneous mole, fleshy mole, or hæmatoma mole) and the hydatidiform mole (vesicular mole). The blood mole results from progressive or recurrent slight hæmorrhages during the first three months of pregnancy, but hæmorrhages insufficient in quantity to produce an abortion. The blood forms a clot, which may be retained for several months and become solidified. Hydatidiform mole is a disease of the young chorionic villi, characterized by the growth of an immense number of irregular clusters and chains of grape-like cysts from the very minute to bodies four-fifths of an inch in diameter. The causation is unknown. Both forms occur in the first half of the pregnancy and are characterized by undue enlargement of the uterus and hæmorrhagic discharge.
