Placental chorioangioma: a rare cause of fetomaternal transfusion with maternal hemolysis and fetal distress.

Multiple placental chorioangiomas in a 31-year-old woman led to a severe, acute fetal-to-maternal transfusion and maternal hemoglobinuria from hemolysis of the fetal red blood cells. Fetal distress was manifest by a sine wave fetal monitor pattern. A severely asphyxiated infant was delivered by cesarean section. The infant did well after transfusion therapy.

Congenital nephrogenic diabetes insipidus in a baby girl.

A 6-week-old girl with fever, hypernatraemia, dehydration, and polyuria failed to concentrate urine in response to exogenous vasopressin administration. There was no family history of nephrogenic diabetes insipidus. When she was 15 months old, the infusion of vasopressin did not produce an increase in urinary cyclic-AMP.
