New concepts in the measurement of itch

We tend not to rely on ‘measurements’ much in dermatology. We might record the dimensions of a naevus for later reference, but when making a diagnosis or monitoring the success of treatment, we usually have to rely on ‘softer’ signs; for example, does the patient report more or less itch? The problem with this approach is that it is difficult to relate one person’s interpretation of intensity to another’s.
