Resumo
OBJECTIVE
To critique Rudolf Virchow's medical school dissertation on rheumatism and the cornea and to determine whether it might have anticipated his remarkable career in medicine.
METHODS
Review of the English translation of Rudolf Virchow's de Rheumate Praesertim Corneae written in 1843.
RESULTS
The dissertation was more than 7000 words long. Virchow considered rheumatism as an irritant disorder not induced by acid as traditionally thought but by albumin. He concluded that inflammation was secondary to a primary irritant and that the "seat" of rheumatism was "gelatinous" (connective) tissues, which included the cornea. He divided kerato-rheumatism into different varieties. The prognosis of keratitis was variable, and would eventually lapse into "scrofulosis, syphilis, or arthritis of the cornea."
CONCLUSIONS
Virchow's dissertation characterizes rheumatism in terms of chemical and tissue interactions that make little sense in the context of today's knowledge of rheumatic disease and keratitis. Ironically, many of these concepts were made obsolete by the cellular model of disease that Virchow championed. Virchow decided to pursue the study of rheumatism through the cornea because he thought that the cornea was an ideal tissue to study disease. This discernment was passed on to his students whose seminal contributions to general pathology were based on research with the cornea. It is debatable whether Virchow's insight into the importance of the cornea in biomedical research at such an early stage of his career could have predicted his monumental contributions to medicine.
