Diagnosis and management of scalp ringworm

Our preference for spelling out abbreviations led to an editing slip in this Clinical Review article by L C Fuller and colleagues (8 March, pp 539-41). We expanded “id reaction” to “identity reaction” in both the text and the legend to figure 3; sadly this made no sense. An id reaction is an immunological response that occurs at some distance from the original infection and may be triggered at the start of treatment.
