A Single-Center Retrospective Study of Pediatric Vitiligo in a Tertiary Hospital.

Vitiligo is a common disorder; however, its management is unknown by many primary-care doctors and pediatricians. Most articles focus on adults; we analyze the characteristics and impact on children. A single-center retrospective study was conducted over 10 years on 254 children diagnosed with vitiligo.

Thermography as a Method for Bedside Monitoring of Infantile Hemangiomas.

Infantile hemangiomas occur in 3 to 10% of infants. To predict the clinical course and counsel on treatment, it is crucial to accurately determine the hemangiomas' extension, volume, and location. However, this can represent a challenge because hemangiomas may present irregular patterns or be covered by hair, or their depth may be difficult to estimate.

Vulvar dermatoses: a cross-sectional 5-year study. Experience in a specialized vulvar unit.

Background: Vulvar diseases are common in the general population and have a negative impact on the quality of life.

Objectives: To describe our experience as dermatologists in the management of vulvar dermatosis consultations.

Methods: A retrospective observational study was conducted with patients who attended monographic vulvar consultations over a 5-year period.

Inter- and intra-observer variability in the selection of therapy for infantile hemangiomas among pediatric dermatologists in Spain.

Background: Guidelines and expert recommendations on infantile hemangiomas (IH) are aimed at increasing homogeneity in clinical decisions based on the risk of sequelae.

Objective: The objective was to analyze the inter- and intra-observer agreement among pediatric dermatologists in the choice of treatment for IH.

Methods: We performed a cross-sectional inter-rater and intra-rater agreement study within the Spanish infantile hemangioma registry.

Novel Non-Invasive Quantification and Imaging of Eumelanin and DHICA Subunit in Skin Lesions by Raman Spectroscopy and MCR Algorithm: Improving Dysplastic Nevi Diagnosis.

Malignant melanoma (MM) is the most aggressive form of skin cancer, and around 30% of them may develop from pre-existing dysplastic nevi (DN). Diagnosis of DN is a relevant clinical challenge, as these are intermediate lesions between benign and malignant tumors, and, up to date, few studies have focused on their diagnosis. In this study, the accuracy of Raman spectroscopy (RS) is assessed, together with multivariate analysis (MA), to classify 44 biopsies of MM, DN and compound nevus (CN) tumors.

Sequelae following infantile haemangiomas treated with propranolol.

Background: Oral propranolol accelerates the involution of infantile haemangiomas (IHs). However, it is not clear whether IHs treated with oral propranolol are associated with fewer sequelae than when left untreated.

Objectives: To quantify and describe sequelae associated with IHs treated with oral propranolol, and to explore whether treated IHs are associated with fewer sequelae than untreated IHs.

Unilateral clubbing-like digital thickening as a clinical manifestation of low-flow vascular malformations: a series of 13 cases.

Background: Digital clubbing is a well-known clinical sign characterized by thickening of the distal phalanges of the fingers and toes. Unilateral clubbing occurs less frequently. A previous report showed for the first time two cases of unilateral clubbing as a clinical manifestation of lower limb venous malformation.

Efficacy and Safety of Topical Timolol for the Treatment of Infantile Hemangioma in the Early Proliferative Stage: A Randomized Clinical Trial.

Importance: Treatment of infantile hemangioma (IH) with topical timolol in the first 2 months of life (early proliferative phase) may prevent further growth and the need for treatment with oral propranolol. To our knowledge, no studies have determined whether beginning early treatment with timolol for IH is better than in other proliferative stages.

Objective: To evaluate the efficacy and safety of timolol maleate solution, 0.

Direct-to-consumer, store-and-forward teledermatology with dermoscopy using the pharmacist as patient point-of-contact.

Objective(s): To evaluate the frequency of nonmelanoma skin cancer (NMSC), NMSC precursors, and melanoma on a store-and-forward dermatology model featuring the pharmacist as the patient's point-of-contact. The secondary objective was to define lesion changes and symptoms perceived by patients (clinical prediction rules by nonexpert observers) that can be predictive of malignity.

Methods: A cross-sectional study of teledermatology consultation was performed.

Long-lasting contact dermatitis in patients with atopic dermatitis or psoriasis.

Background: The aetiology of contact dermatitis, a common inflammatory skin disorder, is often complex and multifactorial.

Objectives: To describe the characteristics of patients with contact dermatitis who also have concomitant atopic dermatitis or psoriasis.

Methods: Between 2000 and 2011, adult patients with chronic contact dermatitis (six months or more), which also had concomitant atopic dermatitis or psoriasis, were recruited for a descriptive retrospective study in a tertiary care Spanish hospital.

Recalcitrant trametinib-induced paronychia treated successfully with topical timolol in a pediatric patient.

Paronychia has been described as a side effect in patients undergoing treatment with MEK (mitogen activated protein kinase enzyme) inhibitors. It is usually a recurrent condition that can have a significant impact in the quality of life. Topical beta blocker treatment has been described as an effective therapy in antineoplastic-induced pyogenic granulomas and in antineoplastic-induced paronychia.

Expression patterns of aquaporin 1 in vascular tumours.

Background: Aquaporins (AQPs) are a family of water channels expressed in various body tissues. Beyond osmotic balance, AQPs have recently been confirmed to be involved in processes related to cancer (tumour proliferation, angiogenesis, etc.).

High SLC7A11 expression in normal skin of melanoma patients.

Background: Melanoma is one of the highest metastatic cancers and its incidence is rapidly increasing. A great effort has been devoted to determine gene mutations and expression profiles in melanoma cells, but less attention has been given to the possible influence of melanin synthesis in melanocytes on melanomagenesis. SLC7A11 encodes the cystine/glutamate antiporter xCT and its expression increases the antioxidant capacity of cells by providing cysteine that may be used for glutathione (GSH) synthesis.

Expression Pattern of Aquaporin 1 and Aquaporin 3 in Melanocytic and Nonmelanocytic Skin Tumors.

Objectives: Study of aquaporin 1 (AQP1) and aquaporin 3 (AQP3) expression to understand its potential role in the pathophysiology of skin cancer.

Methods: Analysis of AQP1 and AQP3 expression by immunohistochemistry of 72 skin biopsy specimens from melanocytic skin tumors, nonmelanocytic tumors, or healthy samples.

Results: AQP1 showed strong labeling in 100% of benign common melanocytic nevi.
