Treatment of persistent painful nodules of hidradenitis suppurativa with cryotherapy.

We report outcomes for 10 patients with persistent painful nodules of hidradenitis suppurativa treated with cryotherapy. Eight patients reported improvement and to date have had no recurrence of lesions at the treated sites. Most patients had significant pain during and after treatment. Eight patients had post-treatment ulceration, infection or both. The average number of days for the treatment areas to heal was 25. Seven patients rated cryotherapy as better than oral antibiotics and eight patients would consider this treatment again in the future. Cryotherapy can be an effective treatment for patients who have limited but persistent painful nodules. However, patients must be warned about pain, prolonged healing time and risk of infection after the procedure.

Diluted Compositae mix versus sesquiterpene lactone mix as a screening agent for Compositae dermatitis: a multicentre study.

The objective of this study was to compare diluted Compositae mix with sesquiterpene lactone mix as a marker for Compositae dermatitis. Patients undergoing diagnostic patch testing in 8 British Isles patch test centres were also patch tested to sesquiterpene lactone mix (0.1% pet.) and Compositae mix (3% pet. or 0.6% pet.). Of a total of 5574 patients tested, 71 (1.3%) reacted to Compositae mix, 57 (1.0%) reacted to sesquiterpene lactone mix, and 45 to both. Diluted Compositae mix remained a more sensitive screening marker for Compositae allergy. We recommend that patients are patch tested to both agents.

Survey of patch testing in Scotland.

We have surveyed Scottish dermatologists to establish the extent of patch testing, to assess the reasons for referral and to document resources and methods used by dermatologists. 104 questionnaires were sent to members of the Scottish Dermatological Society. 82 questionnaires (79%) were returned. 50% of respondents were consultants, 27% were trainees and 23% held staff grade or clinical assistant positions. The mean waiting time for a patch test appointment was 4.5 months. The most frequent reasons for patch testing were localized eczema, eczema not responding to conventional treatment, occupational eczema, history of contact sensitivity and eczema of uncertain cause. 17 of 82 respondents (21%) were the principal clinicians supervising patch testing in their hospitals. 11 of 17 read reactions at 2 and 4 days. Mean time spent on advising patients was 13 min per patients. 7 of 17 were dissatisfied with resources available for patient education and 16 of 17 felt they would benefit from a central source for patient information. Only 4 of 17 centres recorded patch test results on a database and 3 centres regularly reviewed their patch test results. In conclusion, we have identified areas of patch testing that require further improvement.
