Enhanced Insights into Frontal Fibrosing Alopecia: Advancements in Pathogenesis Understanding and Management Strategies
Full text linkFrontal fibrosing alopecia (FFA) represents a distinctive form of primary lymphocytic scarring alopecia characterized by fronto-temporal hair recession and eyebrow hair loss. While predominantly affecting postmenopausal women, FFA also occurs in women of reproductive age and men, with variations observed across different ethnic groups. Genetic predisposition, environmental factors and inflammatory pathways contribute to its pathogenesis, with evolving diagnostic criteria enhancing accuracy. FFA treatment lacks standardization, encompassing topical, systemic and physical therapies, while hair transplantation remains a temporary solution. This article reviews the current understanding of FFA, aiming to provide clinicians with updated insights for its management
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Penile melanocytoma
No full textDiagnosing mucosal pigmented lesions poses challenges due to the necessity of considering various differential entities. We present the case of an 18-year-old man with a histologically confirmed pigmented epithelioid melanocytoma (PEM) of the penile shaft, describing its clinical presentation, dermoscopy and histology. PEM is a rare neoplasm predominantly observed in young individuals and adults, typically found on the trunk and extremities, but it can also affect oral and genital mucosae. Its diagnosis and management present considerable challenges, necessitating a multidisciplinary approach
