Vitamin K deficiency bleeding and early infant male circumcision in Africa.

Background: Early infant (1-60 days of life) male circumcision is being trialed in Africa as a human immunodeficiency virus prevention strategy. Postcircumcision bleeding is particularly concerning where most infants are breastfed, and thus these infants are at increased risk of vitamin K deficiency bleeding.

Case: During a circumcision trial, one infant bled for 90 minutes postprocedure.
