Have you tried the Panamanian Embassy to see if they can put you in touch with the appropriate department?
I've found some embassies to be very helpful, others to be almost useless, but it's worth a try.
I can't find a website or e-mail address, but the Panama Embassy in the U.S. is at:
2862 McGill Terrace, NW, Washington DC 20008
Telephone: (202) 483-1407
