Two pregnant women with vomiting and fits, ,

Two women with hyperemesis gravidarum were first seen with a short history of confusion diplopia, unsteadiness, and fits caused by Wernickeʹs encephalopathy. The neurologic presentation had been precipitated by a carbohydrate load inadvertently administered without vitamin supplementation. We stress the importance of prescribing thiamine supplements to all women with prolonged vomiting during pregnancy.(Am J Obstet Gynecol 1997;177:1539-40.)
