Answers: 1—B; 2—D; 3—C; 4—A; 5—B

1. Franz Wegener was a member of the Nazi party and may have been involved in human experiments in one of the Jewish ghettos. Hans Reiter (Reiter’s syndrome) also was found guilty of involvement in the deaths of hundreds of inmates at the Buchenwald concentration camp.
2. The Finkelstein test is the classic diagnostic test for de Quervain tendinosis. It determines if there is tenosynovitis in the abductor pollicis longus and extensor pollicis brevis tendons of the wrist. Ulnar deviation of the wrist causes pain along the course of these tendons when the thumb is held in the fisted hand.
3. Same explanation as above.
4. Trevor disease (dysplasia epiphysealis hemimelica) is a rare developmental disorder affecting the epiphyses in young children. It is most commonly found around the knee, talus, tarsal navicular, and cuneiform joints. A continuous increase in the size of the lesion can cause pain and deformity, requiring excision of the mass.
5. Cornelia de Lange syndrome is a congenital condition that usually includes growth retardation, developmental delay, hirsutism, limb abnormalities, and facial growth discrepancies. Professor de Lange lived and worked in Amsterdam.
