Hair follicle sulfotransferase activity and effectiveness of oral minoxidil in androgenetic alopecia.

Background: Androgenetic alopecia (AGA) is common. While topical minoxidil remains the only FDA-approved therapeutic for AGA, its efficacy is limited in stimulating clinically significant hair regrowth over the longer term. Oral minoxidil, which is used off-label, is a promising alternative; however, its effectiveness and underlying mechanisms warrant further investigation.

Assessing the Efficacy of Monthly 308 nm Excimer Lamp Double-Stacked Pulse Adjusted Therapy for Alopecia Areata.

Introduction: Alopecia areata (AA) is an autoimmune disease characterized by T cell-mediated attack on the hair follicle. Although there are a wide range of therapies, the majority of them are not satisfactory due to side effects, pain due to intralesional injections or limited efficacy. In this study, we sought to evaluate the efficacy, influence factors, and safety of 308 nm excimer lamp used in a monthly basis in a double-stacked pulse manner for the treatment of AA.

Value of the Lymphocyte Transformation Test for the Diagnosis of Drug-Induced Hypersensitivity Reactions in Hospitalized Patients with Severe COVID-19.

In the first wave of COVID-19, up to 20% of patients had skin lesions with variable characteristics. There is no clear evidence of the involvement of the SARS-CoV-2 virus in all cases; some of these lesions may be secondary to drug hypersensitivity. To analyze the possible cause of the skin lesions, we performed a complete allergology study on 11 patients.

Randomized double-blind placebo-controlled clinical trial to evaluate the effect of a mixture of probiotic strains on symptom severity and use of corticosteroids in children and adolescents with atopic dermatitis.

Background: The intestinal microbiota is altered in patients with atopic dermatitis (AD) when compared with those of the healthy population. Some interventions with specific probiotic preparations already demonstrate a change in composition of this microbiota accompanied by improvement in the disease.

Objectives: This research work was designed to evaluate clinical efficacy of the probiotic preparation, and to measure the effect of the intervention on the total dose of corticosteroids administered to subjects.

Methyl Aminolaevulinic Acid versus Aminolaevulinic Acid Photodynamic Therapy of Actinic Keratosis with Low Doses of Red-Light LED Illumination: Results of Long-Term Follow-Up.

Photodynamic therapy (PDT) treatment for multiple actinic keratosis (AK) has been found effective when lower doses of red light were used with methyl aminolaevulinic acid (MAL). The aim of this study was to compare the results of lower doses of red light conventional PDT (h-PDT, 16 J/cm2) with MAL and aminolaevulinic acid (ALA) in a long-term follow-up. Patients with more than five symmetrical AK on the scalp who were candidates for PDT were selected and divided randomly between MAL and ALA treatment and patients were followed at 3 and 12 months.

A patient with COVID-19 and a skin rash.

A woman presented to the emergency department during the COVID-19 pandemic, reporting a slightly pruritic rash that had developed five days after the onset of fever, cough and malaise.

Prescribing Habits for Androgenic Alopecia among Dermatologists in Spain in 2019-2020: A Cross-Sectional Study.

Background: In 2017, we carried out a cross-sectional study with the aim of describing androgenic alopecia (AGA) prescription habits among dermatologists who practice in Spain. Three years later, we repeated this study with the aim of describing the current situation and comparing it with previous data.

Material And Methods: Descriptive cross-sectional study using online questionnaires autocompleted by dermatologists working in Spain.
