Inequalities in the patterns of dermoscopy use and training across Europe: conclusions of the Eurodermoscopy pan-European survey.

BACKGROUND: Dermoscopy is a widely used technique, recommended in clinical practice guidelines worldwide for the early diagnosis of skin cancers. Intra-European disparities are reported for early detection and prognosis of skin cancers, however, no information exists about regional variation in patterns of dermoscopy use across Europe. OBJECTIVE: To evaluate the regional differences in patterns of dermoscopy use and training among European dermatologists. MATERIALS & METHODS: An online survey of European-registered dermatologists regarding dermoscopy training, practice and attitudes was established. Answers from Eastern (EE) versus Western European (WE) countries were compared and their correlation with their respective countries' gross domestic product/capita (GDPc) and total and government health expenditure/capita (THEc and GHEc) was analysed. RESULTS: We received 4,049 responses from 14 WE countries and 3,431 from 18 EE countries. A higher proportion of WE respondents reported dermoscopy use (98% vs. 77%, p<0.001) and training during residency (43% vs. 32%) or anytime (96.5% vs. 87.6%) (p<0.001) compared to EE respondents. The main obstacles in dermoscopy use were poor access to dermoscopy equipment in EE and a lack of confidence in one's skills in WE. GDPc, THEc and GHEc correlated with rate of dermoscopy use and dermoscopy training during residency (Spearman rho: 0.5-0.7, p<0.05), and inversely with availability of dermoscopy equipment. CONCLUSION: The rates and patterns of dermoscopy use vary significantly between Western and Eastern Europe, on a background of economic inequality. Regionally adapted interventions to increase access to dermoscopy equipment and training might enhance the use of this technique towards improving the early detection of skin cancers.

Ultraviolet-B treatment for cutaneous lichen planus: our experience with 50 patients.

BACKGROUND: Previous small reports suggested the role of ultraviolet (UV)-B in the management of cutaneous lichen planus. OBJECTIVE: To summarize our experience with UVB in a relatively large study group looking specifically into predictive factors for complete response and the long-term relapse rates. METHODS: A retrospective analysis of 50 patients with generalized cutaneous lichen planus, treated by broad or narrow band UVB. RESULTS: Seven and 43 patients were treated by broad and narrow band UVB, respectively. Complete response was achieved in 70% and 85% of those were still in remission after a median of 34.7 months. The complete response rate and the need for higher cumulative exposure doses were not influenced by sex, age, skin type, presence of additional diseases, failure of previous treatment or disease duration. LIMITATIONS: This is a retrospective non-randomized analysis of a usually self-limiting disease. CONCLUSION: UVB is a safe and efficient treatment option for generalized cutaneous lichen planus.

Pigmented lesions clinic for early detection of melanoma: preliminary results.

BACKGROUND: Early detection of malignant melanoma of the skin is the most important factor in patient survival. Naked-eye diagnostic sensitivity and specificity are low. Patients with multiple nevi are at high risk to develop melanomas and the clinical follow-up of such patients is difficult, resulting in missed melanomas on the one hand and unnecessary biopsies on the other. OBJECTIVES: To describe the set-up of a special clinic aimed at early detection of melanoma and follow-up of high risk patients and preliminary results from 20 months of operation. METHODS: We established a pigmented lesions clinic based on a digital photography studio enabling documentation and comparison over time of full body photography and dermoscopy. RESULTS: In the first 20 months of work, 895 patients were seen, 206 of them for follow-up visits. A total of 29,254 photos were taken. Altogether, 236 lesions were suspicious (either clinically or dermoscopically) and the patients were advised to excise them. Seven melanomas were found in this initial examination (which did not include long-term follow-up). CONCLUSIONS: With multimode photographic cutaneous surveillance, early detection of melanoma in high risk patients has been reported. Our clinic utilizes the same techniques and diagnostic algorithm as other leading clinics throughout the world, thus enabling us to deliver better follow-up for those patients.

Patterns of recurrence in patients with melanoma after radical lymph node dissection.

HYPOTHESIS: Previous interventions (excisional biopsy, incomplete dissection) in the regional basin that drain a melanoma site prior to definitive surgical procedures significantly increase the risk of melanoma recurrence in the surgical field. DESIGN: Retrospective analysis. SETTING: Tertiary care referral center. PATIENTS: One hundred forty-one consecutive patients who underwent radical lymph node dissection (RLND) either in the groin or the axilla owing to malignant melanoma were followed up for a median period of 41 months. INTERVENTIONS: All of the 141 patients received either elective or therapeutic RLND. Their medical records were analyzed for demographic data, disease history, previous treatments, recurrence patterns, and survival. MAIN OUTCOME MEASURES: Patterns of first recurrence after RLND and survival. RESULTS: Radical lymph node dissection was performed on 148 lymph node basins (141 patients; 86 axillae and 62 groins). Nineteen patients (13%) received previous open interventions in the lymph node basin (tampering) other than radical dissection. Radical lymph node dissection was performed prophylactically in 38 basins (26%), for palpable disease in 75 (51%), and for a positive sentinel node in 35 (24%). There were 74 failures (52%) of RLND: 51 patients (70%) with systemic disease, 12 (16%) with recurrence in the surgical field, 9 (11%) with in-transit metastases, and 2 (3%) with local recurrence. On multivariate analysis, the only significant predictors of recurrence after RLND were Breslow thickness of greater than 4 mm (P = .02), tampering (P = .01), and lymph node capsular invasion (P = .001). Tampering was the only independent prognosticator of failure in the surgical field, as tampering was noted in 10 (83%) of 12 patients with failure in the surgical field as compared with 6 (10%) of 62 patients with other types of first failures (P<.001). This effect did not translate into a survival difference (P = .54). Failure in the surgical field was not detected in any of the patients who underwent sentinel lymph node biopsy. CONCLUSIONS: Previous interventions (excisional biopsy, incomplete dissection) in the regional basin that drain a melanoma site prior to definitive surgical procedures significantly increase the risk of melanoma recurrence in the surgical field, and they should be avoided. Fine-needle aspiration and sentinel node biopsy, performed with strict surgical oncologic techniques, are safe with regard to failure in the surgical field.
