Papillon-Lefèvre syndrome is an autosomal recessive disorder characterized by palmoplantar hyperkeratosis and aggressive periodontitis. The aim of the study was to identify underlying cathepsin C mutations in 39 subjects with Papillon-Lefèvre syndrome and to explore any phenotypic associations. Genotyping and mutation analyses were performed using standard molecular techniques, and dermatologic ...

Hyperreactivity on re-exposure of previous allergic contact dermatitis skin areas has been previously demonstrated. This study aimed to investigate in methyldibromoglutaronitrile (MDBGN) allergic patients whether skin with previous allergic dermatitis from MDBGN showed an augmented response on re-exposure by both a patch test challenge and a use test with a liquid soap preserved with MDBGN. MDBGN ...

We studied the effects of prolonged topical application of tacrolimus on immediate hypersensitivity reactions. Tacrolimus, betamethasone or petrolatum was applied to the footpad of mice for up to 28 days after immunization, and the foot-swelling response to allergen was estimated. The reactions in tacrolimus-treated mice decreased significantly from day 14, while those in betamethasone-treated mi ...

The aim of this study was to evaluate the association between psoriasis severity and concentrations of matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in plasma and scales from psoriatic lesions, measured with an enzyme immunoassay in 24 patients and analysed with respect to psoriasis area and severity index (PASI). The mean plasma concentrations of both pr ...

Palmoplantar psoriasis is a chronic disease, which is very resistant to treatment and often leads to severe disabilities. Photochemotherapy employing psoralens combined with UVA irradiation (PUVA) is a well-accepted therapy for palmoplantar psoriasis. Its topical application (bath PUVA; cream PUVA) avoids the typical side effects of orally applied psoralens. We compared the efficacy of cream PUVA ...

Preclinical data suggest that topical methyl aminolevulinate photodynamic therapy may have potential in preventing new skin lesions in transplant recipients. An open intra-patient randomized study investigated the prevention potential of this treatment in 27 renal transplant patients with actinic keratoses and other skin lesions in two circular contralateral areas (5 cm diameter). The treatment a ...

The efficacy and safety of 0.3% tacrolimus gel and 0.5% tacrolimus cream compared with calcipotriol ointment were evaluated in adults (n =124) with mild to moderate plaque psoriasis. Treatment was twice daily for a maximum of 12 weeks. Clinical efficacy was assessed by the percentage change in the local psoriasis severity index of a target lesion between baseline and week 12. By week 12, the medi ...

Topical pimecrolimus and narrowband ultraviolet B (UVB) are both known to be effective in treating atopic dermatitis. We compared the clinical efficacy of monotherapy with either twice daily topical 1% pimecrolimus cream or twice weekly narrowband UVB, and combination therapy in 26 children and adolescents with moderate to severe atopic dermatitis in a half-side manner for 6 weeks. Twenty-four pa ...

Langerhans’ cell histiocytosis summarizes a spectrum of diseases on the basis of histogenetic criteria. These are characterized by an accumulation of cells with Langerhans’ cell phenotype in one or multiple organs. Up to 50% of patients with either single or multi-organ manifestation of Langerhans’ cell histiocytosis initially present with cutaneous symptoms. Nevertheless, cutaneous Langerha ...

A 64-year-old woman with a clinically diagnosed ‘lentigo simplex’ on her right cheek was dermatologically treated several times with a CO 2 laser. Three years later she showed a metastasis of a malignant melanoma in her right parotid gland. Considering this case, as well as other published cases reporting malignant melanomas occurring after laser treatment, we again underscore that naevomelan ...

Epidemiological studies on cutaneous melanoma in Mediterranean countries are scarce. Our aim was to perform a descriptive analysis of melanoma cases diagnosed in Valencia, Spain, and to evaluate the relationship between Breslow thickness and some clinical features. A total of 1571 patients with histologically confirmed cutaneous malignant melanoma diagnosed at the two main referral melanoma centre ...
