Beauty and the Biologic: Artistic Documentation of Scientific Breakthrough in Psoriasis.

The making of wax moulages was an exclusive and sought-after art that was primarily used for teaching, but also to document clinical and laboratory research during the first half of the 20th century. Applying the technique of moulage-making to document a case of psoriasis improvement for posterity, a moulage of the trunk of a patient with psoriasis vulgaris was taken prior to treatment with biologics - adalimumab, a TNF-α antagonist - and again 3 month after adalimumab was first given. Our modern moulage shows in the most realistic way the science-driven improvement of psoriasis achievable nowadays with biologics.

History of lasers in dermatology.

In the 1950s, based on the theory of stimulating radiant energy published by Albert Einstein in 1916, the collaboration of physicists and electrical engineers, searching for monochromatic radiation to study the spectra of molecules, led to the invention of the first laser in 1960. Ophthalmologists and dermatologists were the first to study the biological effects and therapeutic possibilities of laser beams. The construction of new laser systems emitting energy at different wavelengths or with different durations, as well as the development of new concepts of the biomedical effects, led to its broad use in surgery in the treatment of vascular and pigmented lesions as well as cosmetic applications.

Traces of Marion B. Sulzberger in the Museum of Wax Moulages in Zurich and their importance for the history of dermatology.

Marion B. Sulzberger was one of the most famous American dermatologists. He had received his training in dermatology in Zurich (Switzerland) from 1926 to 1929.
