Correction: Interactive case report: Treatment of nausea and vomiting during pregnancy

The use of “primiparous” in an interactive case report (31 January, p 276) seems to have caused confusion. A subsequent rapid response advising that we had wrongly used the word primiparous in the report prompted us to publish a correction (27 March, p 762). It now seems that perhaps primiparous was correct after all. Dorland's Illustrated Medical Dictionary (30th edition) defines primiparous as “bearing or having borne but one child” (as was the case in our article) and “primipara” as “a woman who has had one pregnancy that resulted in a fetus that attained a weight of 500 g or a gestational age of 20 weeks, regardless of whether the infant was living at birth.”
