  In this talk I first present a short review of fluctuations in
$e^+e^-$-annihilations. I then describe some new results on FD correlations.
Experimental analyses of $pp$ and $\Lambda\Lambda$ correlations indicate a very
small production radius. This result relies very strongly on comparisons with
MC simulations. A study of the approximations and uncertainties is these
simulations imply that it is premature to draw such a conclusion from the data.
