Three months later, the 3D group still had significantly higher mean percentage scores than did the 2D group for lesion recognition (47 vs 40, P =.

Immediately after the teaching intervention, the 3D group had significantly higher mean percentage scores than did the 2D group for overall performance (71 vs 65, P =. Mean scores in the domains of morphology, lesion and rash recognition, lesion and rash management, and overall performance assessed at baseline, immediately after, and 3 months after each group's respective teaching intervention. University of Massachusetts Medical School.Ī 1-hour teaching intervention using a lecture with 2D images (2D group) or using 3D prosthetic mimics of lesions and eruptions (3D group). To evaluate the effectiveness of a teaching method that uses 3-dimensional (3D) silicone-based prosthetic mimics of common serious lesions and eruptions and to compare learning outcomes with those achieved through the conventional method of lectures with 2-dimensional (2D) images. This paper aims (i) to outline Erich Hoffmann's role for and his contribution to the moulage collection and (ii) to give the first biographic details about the two outstanding dermatologic moulage makers of the collection of Bonn. Kaltschmidt has only been known to have worked as moulage maker in Rostock, while the biographic details of both her and H. Two excellent wax moulage makers, Auguste Kaltschmidt and Hermann Hessling, produced most of these masterpieces between 19. This almost unknown collection consists of more than 1,000 delicate and well conserved wax models. He founded one of the largest moulage collections in Germany. In 1910 Erich Hoffmann, who discovered Spirochaeta pallida together with Fritz Schaudinn, became head of the department of dermatology in Bonn. Dermatology departments all over the world created wax moulages collections to teach students and doctors as well as to document research. The tradition of wax models in Dermatology, also named moulages, is about 200 years old.
