Recent genome-wide association studies (GWASs) have identified >20 new loci associated with the susceptibility to psoriasis vulgaris (PsV) risk. We investigated the association of PsV and its main clinical subphenotypes with 32 loci having previous genome-wide evidence of association with PsV (P < 5e-8) or strong GWAS evidence (P < 5e-5 in discovery and P <(More)
BACKGROUND Sunscreens have long been used to protect against the acute effects of UV radiation. They can also have protective effects on chronic UV-induced changes, such as photoaging and skin cancer. Recent studies have focused on marine organisms as a source of natural bioactive molecules and some UV-absorbing algal compounds are under investigation as(More)
In an attempt to decrease the risk of fascial dehiscence, a new suture technique for fascial closure is proposed, referred to as the "secured" stitch. The secured interrupted stitch is performed by taking a double bite of fascia at each traditional site of fascial puncture. Relative strength of the secured interrupted stitch in comparison with the simple(More)
BACKGROUND The CD30 (Ki-1)-positive lymphoproliferative disorders show a non-epidermotropic infiltrate of large-sized pleomorphic T cells, being extremely rare those that develop from B cells. CLINICAL CASE A 51-year-old white man presented with a 8x10 cm lobulated scalp tumor that had developed during the previous 8 months. Histopathology demonstrated a(More)
A case of leiomyosarcoma of the penis in a farmer aged 70 is described. The patient was treated by excision/biopsy, and six months later three little tumors recurred on the glans and prepuce. A wide local excision and direct suture was carried out. No troubles happened in the next eight months. The ultrastructural study confirmed the histogenesis showing:(More)
BACKGROUND Surgical excision is the preferred method of eradicating Bowen´s disease (BD). Photodynamic therapy (PDT) has been successfully used for treatment of actinic keratosis, basal cell carcinoma, and BD. OBJECTIVE Our aim was to evaluate the efficacy and tolerability of PDT for treatment of extensive BD. METHOD Eighteen patients with 23(More)
BACKGROUND Leishmania coinfection is frequently seen in human immunodeficiency virus (HIV)-infected patients in endemic areas, and from time to time the protozoan is detected in cutaneous biopsies. OBJECTIVE To establish the characteristics and possible ethiologic role of the presence of Leishmania in these lesions. METHODS We studied 12 cutaneous(More)
A calcipotriol/hydrocortisone combination ointment has been developed for treating psoriasis on sensitive skin areas such as the face. The efficacy and safety of two calcipotriol/hydrocortisone dose combinations were compared with two concentrations of calcipotriol in the same ointment vehicle in patients with psoriasis on the face and body. Patients were(More)
BACKGROUND Several questionnaires have been used to measure health related quality of life (HRQoL) in patients with psoriasis, few have been adapted for use in Spain; none of them was developed specifically for the Spanish population. The purpose of the study was to validate and assess the sensitivity to change of a new questionnaire to measure HRQOL in(More)
