Nit Picker's Corner 1

There has been a lot of news this week about the Duchess of Cambridge suffering from hyperemesis gravidum. This was described by the BBC and elsewhere (http://www.dailyrecord.co.uk/news/uk-world-news/duchess-of-cambridge-leaves-king-edward-1475838) as 'acute morning sickness'. Medically, however, acute means 'short lasting' (it's the opposite of chronic or 'long lasting'). They obviously mean't 'severe' and did correct it in later bulletins.
