The Lancet has published the results of the Procedural Pain in Premature Infants (Poppi) study, which was run by the Paediatric Neuroimaging Group and co-ordinated by the National Perinatal Epidemiology Unit (Clinical Trials Unit).

Mother holding her premature baby's hand

The year-long study examined the effects of morphine as an analgesic for premature non-ventilated babies undergoing routine eye examinations. Thirty-one infants were enrolled in the trial, and assigned to either morphine or placebo treatment.

The results show that administration of oral morphine to non-ventilated premature infants prior to retinopathy of prematurity screening has the potential for harm without suggestion of analgesic efficacy. Difficulties in measuring infant pain are widely recognised, and the methodology used to measure both analgesic efficacy and side effects of a pharmacological intervention in the Poppi trial sets new standards for the conduct of clinical trials of analgesics in infants.

New evidence for how our brains handle surprise

A new study from the Bruno Group is challenging our perceptions of how the different regions of the cerebral cortex function. A group of ‘quiet’ cells in the somatosensory cortex that rarely respond to touch have been found to react mainly to surprising circumstances. The results suggest their function is not necessarily driven by touch, but may indicate an important and previously unidentified role across all the major cortices.

Language learning difficulties in children linked to brain differences

A new study using MRI has revealed structural brain changes in children with developmental language disorder (DLD), a common but under-recognised difficulty in language learning. Children with DLD aged 10-15 showed reduced levels of myelin in areas of the brain associated with speaking and listening to others, and areas involved in learning new skills. This finding is a significant advance in our understanding of DLD and these brain differences may explain the poorer language outcomes in this group.
