Verdigris and variants on normal. Archimedes August 2019

Last month we asked about newborn baby checks being enhanced with pulse oximetry - this month we’re asking “What should you do with a sacral dimple?” (The answer is not “Throw it in the brig until it’s sober”). The answer - in terms of ultrasounding or not - can be found here (https://adc.bmj.com/content/104/8/816.1). You might also be wondering about the mineralisation of your jejunally fed kids too… I know I’ve spent many minutes wondering about how to spell that .. and if copper really is a trace element of importance beyond it’s pretty rusting. This knowledge thirst too can be slaked - here (https://adc.bmj.com/content/104/8/817) And if that’s not enough, we chat about the sometimes tricky issue of balancing the benefits against the harms of an intervention (or test, or measurement), which involves maths, but only those we teach to primary school children (https://adc.bmj.com/node/208810)

If you do want to know other things, and we’ve not covered them, why just write your own Archi and submit it to us?
