For those at the cutting edge of computers and parturition, there is a gem of an article by Errol Norwitz from Yale (AJOG 2006;194:1510-2). It is about how computers can extract patterns from data fed into them and recognise sequences that are too complex to be picked up by standard computer programmes or our brains. This artificial intelligence resembles human intelligence but can hold and connect more variables simultaneously than can our innate software.
The multi-factorial initiation of labour may yield to such scrutiny and the unravelling may have already begun. These sophisticated programmes make in silico redictions - a term Norwitz uses to describe the complex solutions the computers come up with, as compared to in vitro or in vivo evidence. Presumably in silico will take its place in our new lexicon, so drop it into a ward round casually to impress non JASS readers.
For those needing to be conversant with the modern views of the onset of labour, this editorial is highly recommended.
