Forefoot ultrasounds

Today's little pile of reference links comes from an apparently normal ultrasound in the context of dodgy clinical presentation with a funny black area between the metatarsal heads (?neurovascular bundle? but it seems too big).

So apparently the interwebs are full of people also wanting to know about forefoot sonography.

Here are some places to start looking:

Our little case was a little less homogenous than this neuroma

I'm still lost as to why what I see in the pictures isn't a neuroma or bursa, but at least these few resources are a good place to start in terms of looking at forefoot sonography.

CKD Staging: A Reminder...

I spent a little bit of time working in renal but it's been a few years since then, and my brain failed on telling me to eGFR cutoffs for staging of CKD, so here they are. Thanks Kidney Health Australia!

>60 not CKD if no microalbuminuria, haematuria or structural kidney disease
Stage 1 >/= 90
Stage 2 60-89
Stage 3a 45-59
Stage 3b 30-44
Stage 4 15-29
Stage 5 <15 or on dialysis
