[Clinical tests of medications aimed at healing: proposal for a methodology. Classification of leg ulcers].

: The author analyses the difficulties encountered in practical medicine when, attempting to obtain the cicatrization of leg ulcers. He underlines the necessity, in order to evaluate the action of a drug in a controlled experiment, to impose and to impose upon oneself, certain restrictions so as to be able to observe closely their development and to compare cases, some being tested with an active drug and others with a placebo. Telethermography would seem to be non-surgical instrumental method of great benefit for following the development of the ulcer and assessing the effectiveness of a treatment. Whilst aware of both ethical and economic problems, the author proposes an analytical formula defining the indications of clinical and telethermographical seriousness and a classification of leg ulcers in the light of such an analysis.
