Studies on maturity in newborn infants. IX. Further observations on the use of external characteristics in estimating gestational age

Acta paediatrica Scandinavica

A simple method for assessing maturity based on 8 external characteristics has previously been described. Some new results with the use of this method are now presented. The precision in estimating gestational age is sufficiently good, more than 95% of the infants were correctly estimated within +/- 3 weeks. Reducing the criteria to seven and thereby excluding the ophthalmoscopic examination did not significantly change the precision of the estimation. The examination based on external characteristics is a very simple and useful method for maturity assessment, even in sick newborn infants. Tables for transforming maturity score into gestational age are presented.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
