Diagnosis of pigmented skin lesions by dermoscopy: web-based training improves diagnostic performance of non-experts.

BACKGROUND: Dermoscopy has been shown to enhance the diagnosis of melanoma. However, use of dermoscopy requires training and expertise to be effective. OBJECTIVES: To determine whether an Internet-based course is a suitable tool in teaching dermoscopy, and to evaluate the diagnostic value of pattern analysis and diagnostic algorithms in colleagues not yet familiar with this technique. METHODS: Sixteen colleagues who were not experts in dermoscopy were asked to evaluate the dermoscopic images of 20 pigmented skin lesions using different diagnostic methods (i.e. pattern analysis, ABCD rule, seven-point checklist and Menzies' method), before and after an Internet-based training course on dermoscopy. Mean +/- SEM sensitivity, specificity and diagnostic accuracy, and kappa (kappa) intraobserver agreement were evaluated for each diagnostic method before and after training for the 16 participants. Differences between mean values were assessed by means of two-tailed Wilcoxon rank-sum tests. RESULTS: There was a considerable improvement in the dermoscopic melanoma diagnosis after the Web-based training vs. before. Improvements in sensitivity and diagnostic accuracy were significant for the ABCD rule and Menzies' method. Improvements in sensitivity were also significant for pattern analysis, whereas the sensitivity values were high for the seven-point checklist in evaluations both before and after training. No significant difference was found for specificity before and after training for any method. There was a significant improvement in the kappa intraobserver agreement after training for pattern analysis and the ABCD rule. For the seven-point checklist and Menzies' method there was already good agreement before training, with no significant improvement after training. CONCLUSIONS: We demonstrated that Web-based training is an effective tool for teaching dermoscopy.

Type I lamellar ichthyosis improved by tazarotene 0.1% gel.

The efficacy of tazarotene 0.1% gel in a 30-year-old woman with type I lamellar ichthyosis is reported. The drug was applied to 15% of the total body surface area as follows: once daily for 2 weeks, three times a week for further 2 weeks, followed by a once weekly maintenance application. During the first week of treatment there was partial improvement obtained and in the next 14 days further reduction of scaling within the tazarotene-treated areas was observed. After 4 months of maintenance application, there was a marked overall improvement in the treated areas. Side-effects consisted only of mild pruritus, slight burning and irritation. In essence, the therapeutic benefit obtained was comparable with that of systemic retinoids but without the adverse systemic side-effects. As noted in other reports, tazarotene 0.1% gel seems to be a valuable and safe therapeutic option for this severe genodermatosis.

Pyoderma vegetans and ulcerative colitis.

Pyoderma vegetans (PV) is a chronic, vegetating pustular disorder characterized clinically by erythematous vesiculopustular vegetating cutaneous plaques. Marked epidermal hyperplasia, intraepidermal and subepidermal neutrophilic microabscesses and a dermal inflammatory infiltrate are the prominent histopathological findings. We describe a patient with PV associated with ulcerative colitis and mammary Paget's disease. Pustular eruptions associated with ulcerative colitis are reviewed.

The use of high-dose immunoglobulin in the treatment of pyoderma gangrenosum.

BACKGROUND: Immunosuppressive medications such as corticosteroids and cyclosporin are the most commonly employed therapies in pyoderma gangrenosum. We describe a patient with multiple ulcers of pyoderma gangrenosum on the lower extremities in whom immunosuppressive therapy caused serious side effects and had to be discontinued but who was subsequently treated successfully with high dose intravenous immunoglobulin (IVIG). METHODS: IVIG was given intravenously at a dose of 400 mg/kg per day for 5 consecutive days. After 1 week there was an arrest in the progression of the ulcers and a marked reduction in pain. Two weeks later clinical improvement of the ulcers was observed. Subsequently, IVIG was given at a dose of 1 g/kg per day for 2 consecutive days. RESULTS: The treatment induced a dramatic clinical improvement of one ulcer and healing of the others. Side effects were minimal and well tolerated, and consisted of chills and a slight fever, which resolved with the administration of acetaminophen. CONCLUSION: We feel that IVIG can be used in patients with pyoderma gangrenosum in whom conventional therapies are ineffective or produce serious side effects.
