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.

Clinical Characterization and Treatment Response of Folliculitis Decalvans Lichen Planopilaris Phenotypic Spectrum: A Unicentre Retrospective Series of 31 Patients.

Folliculitis decalvans and lichen planopilaris phenotypic spectrum has been described as a form of cicatricial alopecia. The aim of this study is to describe the clinical and trichoscopic features and therapeutic management of this condition in a series of patients. A retrospective observational unicentre study was designed including patients with folliculitis decalvans and lichen planopilaris phenotypic spectrum confirmed with biopsy.

Safety of Low-Dose Oral Minoxidil in Patients With Hypertension and Arrhythmia: A Multicenter Study of 264 Patients.

Background And Objective: Systemic adverse effects (AE) are a major concern of low-dose oral minoxidil (LDOM) treatment, especially in patients with arterial hypertension or arrhythmia. The objective of this study was to evaluate the safety of LDOM in patients with hypertension or arrhythmia.

Patients And Methods: Retrospective multicenter study of patients with hypertension or arrhythmia treated with LDOM for any type of alopecia.

Recommendations on the Clinical Management of Androgenetic Alopecia: A Consensus Statement From the Spanish Trichology Group of the Spanish Academy of Dermatology and Venererology (AEDV).

Androgenetic alopecia can be challenging to treat due to the wide range of available treatments, most of which are not based on evidence from clinical trials. In addition many of the options do not include androgenetic alopecia among the approved indications according to their summaries of product characteristics. A panel of 34 dermatologists from the Spanish Trichology Society of the Spanish Academy of Dermatology and Venereology (AEDV) used the Delphi method to develop a consensus statement on the management of androgenetic alopecia.

Genotyping of the rs1800440 Polymorphism in CYP1B1 Gene and the rs9258883 Polymorphism in HLA-B Gene in a Spanish Cohort of 223 Patients with Frontal Fibrosing Alopecia.

The pathogenesis of frontal fibrosing alopecia has been linked to specific genetic variants. CYP1B1 codes for a component of the cytochrome p450 machinery that is involved in the metabolism of xenobiotic oestrogens. The study of the prevalence of polymorphisms in this gene may help to understand their role in the development of frontal fibrosing alopecia.

Safety of Low-Dose Oral Minoxidil in Patients With Hypertension and Arrhythmia: A Multicenter Study of 264 Patients.

Background And Objective: Systemic adverse effects (AE) are a major concern of low-dose oral minoxidil (LDOM) treatment, especially in patients with arterial hypertension or arrhythmia. The objective of this study was to evaluate the safety of LDOM in patients with hypertension or arrhythmia.

Patients And Methods: Retrospective multicenter study of patients with hypertension or arrhythmia treated with LDOM for any type of alopecia.

Sonidegib as a Locally Advanced Basal Cell Carcinoma Therapy in Real-life Clinical Setting: A National Multicentre Study.

Background: Basal cell carcinoma (BCC) is the most prevalent cancer. A minority of BCCs have an aggressive behaviour (laBCC) and may require hedgehog pathway inhibitors such as sonidegib as its treatment.

Objective: To describe the use of sonidegib in a large number of patients and provide more data on its real-life efficacy and safety profile.

Prognostic factors for satellitosis or in-transit metastasis in cutaneous squamous cell carcinoma: A multicentric cohort study.

Background: Satellitosis or in-transit metastasis (S-ITM) has clinical outcomes comparable to node-positivity in cutaneous squamous cell carcinoma (cSCC). There is a need to stratify the risk groups.

Objective: To determine which prognostic factors of S-ITM confer an increased risk of relapse and cSCC-specific-death.

Folliculitis Decalvans Has a Heterogeneous Microbiological Signature and Impaired Immunological Response.

Background: Folliculitis decalvans (FD) is a rare primary neutrophilic scarring alopecia whose etiology has not been completely elucidated yet.

Objective: The aim of the study was to determine if the follicular microbiota residing in FD-affected hair follicles had a distinct microbiological signature and if an aberrant immune response was present in the pathogenesis of FD.

Methods: We conducted a cross-sectional study of 10 patients affected by FD.

Mesotherapy With Dutasteride for Androgenetic Alopecia: A Retrospective Study in Real Clinical Practice.

Background: 5-alpha inhibitors are an effective treatment for androgenetic alopecia. Mesotherapy with dutasteride has been proposed as an effective method to improve hair loss and reducing systemic absorption.

Objective: The main objective was to describe the safety profile of mesotherapy with dutasteride in real clinical practice in a large cohort of patients with androgenetic alopecia.

Imiquimod-enhanced immunotherapy with diphencyprone for patients with alopecia areata.

Topical immunotherapy with dyphencyprone (DPCP) is widely used in patients with alopecia areata (AA). It can produce a contact dermatitis that is believed to decrease Th1 response, predominant in AA. It has been shown that imiquimod (IMQ), a topical immunomodulator drug, can produce sensitization to DPCP in patients that do not show signs of contact dermatitis when exposed to DPCP.

Epidermis as a Platform for Bacterial Transmission.

The epidermis constitutes a continuous external layer covering the body, offering protection against bacteria, the most abundant living organisms that come into contact with this barrier. The epidermis is heavily colonized by commensal bacterial organisms that help protect against pathogenic bacteria. The highly regulated and dynamic interaction between the epidermis and commensals involves the host's production of nutritional factors promoting bacterial growth together to chemical and immunological bacterial inhibitors.

Atypical Congenital Triangular Alopecia (Brauer Nevus): Case Report and Review of Literature in Occipital and Mid-Frontal Localizations.

Introduction: Brauer nevus, also known as congenital triangular alopecia (CTA) is a localized alopecia that rarely affects the occipital or mid-frontal region. CTA is a localized follicular hypoplasia, commonly misdiagnosed as alopecia areata. Although named congenital, onset in adulthood is possible.
