<Renfrew, Woolridge and Ross McGill, in their invaluable book 'Enabling
Women
to Breastfeed' (2000) -- been discussed before on lactnet, a review of
evidence, no one in the UK should be thinking of practicing without it, use
the terminology, which I believe they may have taken from Mavis Gunther, a
doc who was writing in the 50's, 'obstructive' and 'infectious'
mastitis....>

Thanks Magda. I agree "obstructive" and "infectious" is probably more
accurate than "infectious" and "non-infectious". Obstructive mastitis may
occur when part of the breast is not well-drained (eg tight clothes, baby
not feeding well), and may be relieved by improved drainage, or may develop
into infective mastitis if the milk can't be moved.

I've just reread the mastitis section of the Renfew et al book to see if
they come to any conclusion about definitions, but they don't really. And
unfortunately their lit search ended in 1997, and we have some more
publications on mastitis since then (eg Cathy Fetherston's work). Let's hope
they get funding to keep updating their review.
