Hyperinvolution.—A condition known as superinvoluiionor hyperinvolution, depending upon a prolongation of the fatty degenerationand atrophy of the parturient uterus, has been known to exist. It is veryinfrequent. In very rare cases the uterus may almost disappear. It is prob-ably the result of profound anemia; protracted lactation may coexist. Thesymptoms are usually not pronounced. Menstruation may not return. Diag-nosis should be made by bimanual examination. For treatment, the child mustbe weaned, tonics administered, the diet made nutritious and generous, andhygienic measures instituted, such as a change of air and scene, with massageor carefully regulated exercises. 3.

This subject, rarely mentioned by obstetricians, hasbeen described by Vineburg. It is known that in connection with involution the uterus becomes smallerat one period than even the non-parous organ; and that it undergoes regener-ation either during or after the lactation period. The period of minimum sizehas been placed by various authorities at any time between six and twentyweeks. This phenomenon is best seen in the multipara, and is much lessmarked in primiparae. Although known as lactation-atrophy, something of thesame sort is seen in mothers who do not nurse their children, although in amuch less degree. If the uterus is studied microscopically during t
