Patients with moderate to severe psoriasis are undertreated. To solve this persistent problem, the consensus programme was performed to define goals for treatment of plaque psoriasis with systemic therapy and to improve patient care. An expert consensus meeting and a collaborative Delphi procedure were carried out. Nineteen dermatologists from different European countries met for a face-to-face discussion and defined items through a four-round Delphi process. Severity of plaque psoriasis was graded into mild and moderate to severe disease. Mild disease was defined as body surface area (BSA) ≤10 and psoriasis area and severity index (PASI) ≤10 and dermatology life quality index (DLQI) ≤10 and moderate to severe psoriasis as (BSA > 10 or PASI > 10) and DLQI > 10. Special clinical situations may change mild psoriasis to moderate to severe including involvement of visible areas or severe nail involvement. For systemic therapy of plaque psoriasis two treatment phases were defined: (1) induction phase as the treatment period until week 16; however, depending on the type of drug and dose regimen used, this phase may be extended until week 24 and (2) maintenance phase for all drugs was defined as the treatment period after the induction phase. For the definition of treatment goals in plaque psoriasis, the change of PASI from baseline until the time of evaluation (ΔPASI) and the absolute DLQI were used. After induction and during maintenance therapy, treatment can be continued if reduction in PASI is ≥75%. The treatment regimen should be modified if improvement of PASI is <50%. In a situation where the therapeutic response improved ≥50% but <75%, as assessed by PASI, therapy should be modified if the DLQI is >5 but can be continued if the DLQI is ≤5. This programme defines the severity of plaque psoriasis for the first time using a formal consensus of 19 European experts. In addition, treatment goals for moderate to severe disease were established. Implementation of treatment goals in the daily management of psoriasis will improve patient care and mitigate the problem of undertreatment. It is planned to evaluate the implementation of these treatment goals in a subsequent programme involving patients and physicians.

Although the population screened during Euromelanoma was relatively young, high rates of clinically suspected melanoma were found. The efficacy of Euromelanoma could be improved by targeting high-risk populations and by better use of dermoscopy and full body skin examination.

Long-term therapy with emollient is effective and well tolerated for the treatment of xerosis in children with atopic dermatitis.

Haemostasis-maintaining platelets are also recognized as important modulators in the regulation of immune response. Activated platelets expressing P-selectin (CD62P) are involved in the extravasation of leucocytes. This study evaluated platelet P-selectin expression as a biomarker for cutaneous inflammation. P-selectin expression was assessed by flow cytometry in 147 successive patients suffering from an inflammatory or infectious skin condition at the day of admission for in-patient treatment as well as a day prior to demission. Forty-one patients admitted for allergy testing served as controls. A commercially available ELISA was used in 17 patients to determine soluble P-selectin in the plasma. In patients with psoriasis, the Psoriasis Area and Severity Index (PASI) was documented as a measure for disease severity. We observed a significant increase in platelet P-selectin expression in patients with inflammatory or infectious disorders, when compared to the control group (3,01% vs. 1,46%; P < 0.000001). Successful treatment resulted in a significant decrease in P-selectin expression to the level of the control group. In the case of psoriasis (n = 47), we found highly significant correlation between P-selectin and PASI (r = 0.51; P < 0.000001), as well as between the change in the PASI and the change in P-selectin expression (r = 0.4; P = 0.006). Platelet P-selectin expression as determined by flow cytometry correlated well with the results of soluble P-selectin, determined by ELISA (r = 0.63; P < 0.01). Thus, platelet P-selectin expression may be used as an efficacy biomarker to monitor treatment success in psoriasis. As platelet P-selectin correlates with soluble P-selectin in patient plasma, which can be measured by ELISA, the latter is feasible also for routine use.

Cathepsin (Cat) L is an important lysosomal proteinase involved in a variety of cellular functions including intracellular protein turnover, epidermal homeostasis and hair development. Hurpin (serpinB13) is a cross-class specific serine protease inhibitor of Cat L. We have analysed the expression and localization of Cat L and hurpin in various inflammatory and neoplastic diseases by immunohistochemistry. Whereas Cat L expression in normal skin was below detection limit, immunoreactivity was detected in chronic inflammatory dermatoses. The highest expression of Cat L was found in psoriasis, atopic eczema and squamous cell carcinoma (SCC) samples. Samples of Lupus erythematosus, folliculitis, acne inversa, chronic leg ulcers and pyoderma gangrenosum demonstrated similar but lower expression for Cat L. In malignant cells of SCC, basal cell carcinoma and malignant melanoma, characteristic staining patterns were observed for Cat L, with more abundant expression at the periphery of the tumor. Expanding our previous work, we found that the expression of hurpin was confined mainly to the basal layer in normal skin samples, whereas hurpin was overexpressed and redistributed in diseased skin. The localization of hurpin in dermatoses and neoplasias differed from that in normal skin in that the highest expression was found in the outermost layers of the granular and upper spinous layers. Similarly to Cat L, the highest expression for hurpin was found in psoriasis and SCC. The results presented here summarize for the first time the expression of the protease Cat L and its inhibitor hurpin in a broad spectrum of skin diseases.

Photodermatoses are skin disorders induced or exacerbated by light. They can be broadly classified into four groups: (i) immunologically mediated photodermatoses (idioapathic); (ii) drug- and chemical-induced photosensitivity; (iii) defective DNA repair disorders; and (iv) photoaggravated dermatoses. The exact pathomechanism of those diverse skin reactions to light radiation remains unclear. Immunologically mediated photodermatoses are the most common dermatoses among all photosesnsitive disorders. The management of photodermatoses starts with clinical recognition of characteristic lesions localized predominantly in light exposed skin. Detailed history-taking, phototesting and photopatch testing are required to establish a correct diagnosis, especially if patients present in disease-free intervals. Classification and short description of distinctive clinical features of most common photodermatoses, several practical aspects of evaluation and management of the patient with photosensitivity will be outlined.

The incidence of BCC in Lithuania is lower than that reported in Northern and Western Europe. The population-based data for BCC from Lithuania are closely comparable, with regard to age, tumour localization and place of residence, with the existing literature from other European cancer registries.
