Ellie, I hope your Father does well. The "enzyme" therapy
is discussed in a previous thread "Collagenase" posted
most recently Nov 9, 2004 (as of this posting.) Auxilium
is the pertinant subject. In a nutshell, in my opinion,
"enzyme" therapy is still years off in the future (if ever)
for Dupuytrens treatment. I believe that trials are still
in progress at Stoney Brook and Stanford Universities in
the US. Financial incentives seem to be the barrier to
progress. Drug companies have more incentive to treat
chronic illnesses affecting large populations rather than
short term treatment for a relatively smaller population.
Statins is a good example of the former. BTC is not Merk nor
Pfizer. NA is the best alternative at present for most of us. Some individuals may still benefit from traditional surgery. Hopefully,Doctors and patients work out those details in the patient's best interest. Good luck.
