IL-36-driven pustulosis: Transcriptomic signatures match between generalized pustular psoriasis (GPP) and acute generalized exanthematous pustulosis (AGEP).

Background: Due to similarities, the distinction between generalized pustular psoriasis (GPP) and acute generalized exanthematous pustulosis (AGEP) has been a matter of debate for a long time.

Objectives: Our aim was to define the molecular features of GPP and AGEP.

Methods: We analyzed skin biopsy samples and clinical data from 125 patients with AGEP, GPP, palmoplantar pustulosis (PPP), plaque psoriasis (PSO), and nonpustular cutaneous adverse drug reactions (ADRs), as well as from healthy skin controls using RNA-sequencing and blinded histopathologic analyses.

SCALPDEX Questionnaire: creation and validation of the Polish language version.

Introduction: Assessing the quality of life (QoL) in patients with various diseases is essential for understanding their well-being and guiding clinical management. Dermatological conditions, particularly those affecting the scalp, significantly impact QoL due to their visible nature, which can affect appearance and social interactions. While general QoL instruments like the Dermatology Life Quality Index (DLQI) exist, disease-specific tools like SCALPDEX are necessary for capturing the unique challenges faced by patients with scalp disorders.

Clinical Utility of Various Formulations of Calcipotriene and Betamethasone Dipropionate for the Treatment of Plaque Psoriasis in Patients Aged 12 Years or Older.

Plaque-type psoriasis is a chronic immune-mediated inflammatory skin disease of uncertain etiology, significantly impacting patient well-being. This chronic condition not only contributes to stigmatization and mental health challenges but also poses an independent risk for cardiovascular and other comorbid diseases. Affecting approximately 60 million people globally, psoriasis manifests primarily as mild-to-moderate disease in about 80% of cases, where topical therapy is pivotal.

Importance: Prurigo nodularis (PN) is a chronic and debilitating skin condition, characterized by intense itch with multiple nodular lesions. Nemolizumab demonstrated significant improvements in itch and skin nodules in adults with moderate to severe PN in a previous 16-week phase 3 study (OLYMPIA 2).

Objective: To assess the efficacy and occurrence of adverse events in adults with moderate to severe PN treated with nemolizumab vs those receiving placebo.

Porokeratoses-A Rare Group of Dermatoses.

Porokeratoses represent a rare group of skin diseases characterized by abnormal keratinization. The condition may have a genetic background and can be triggered by environmental factors, including UV exposure and infections. Several clinical variants of porokeratosis can be distinguished, including Mibelli's porokeratosis, disseminated superficial actinic porokeratosis, superficial disseminated porokeratosis, and porokeratosis palmaris plantaris et disseminata.

Phase 2b randomized clinical trial of amlitelimab, an anti-OX40 ligand antibody, in patients with moderate-to-severe atopic dermatitis.

Background: Amlitelimab, a fully human nondepleting mAb targeting OX40 ligand on antigen-presenting cells, could prevent T-cell-driven inflammation seen in atopic dermatitis (AD).

Objective: This trial evaluated the efficacy and safety of amlitelimab in adults with AD.

Methods: In this 2-part, phase 2b, randomized, double-blinded placebo-controlled trial (ClinicalTrials.

Applying the Atomic Force Microscopy Technique in Medical Sciences-A Narrative Review.

Penetrating deep into the cells of the human body in real time has become increasingly possible with the implementation of modern technologies in medicine. Atomic force microscopy (AFM) enables the effective live imaging of cellular and molecular structures of biological samples (such as cells surfaces, components of biological membranes, cell nuclei, actin networks, proteins, and DNA) and provides three-dimensional surface visualization (in X-, Y-, and Z-planes). Furthermore, the AFM technique enables the study of the mechanical, electrical, and magnetic properties of cells and cell organelles and the measurements of interaction forces between biomolecules.

Evaluation of hair surface structure and morphology of patients with lichen planopilaris (LPP) by atomic force microscopy (AFM).

Background: Lichen planopilaris (LPP) is a chronic lymphocytic skin disease manifested by progressive scarring alopecia. The diagnosis of LPP is made based on histopathological examination, although it is not always definite. The current study evaluates the effectiveness of non-invasive atomic force microscopy (AFM) hair examination in detecting morphological differences between healthy and diseased hair.

Pruritus in Lichen Planopilaris and Frontal Fibrosing Alopecia-Clinical Characteristics and Dermoscopic Correlations.

An Update on Non-Invasive Skin Imaging Techniques in Actinic Keratosis-A Narrative Review.

Nonmelanocytic skin cancers (NMSCs) are currently the most common group of human cancers and include all tumors that are not melanomas. Increased exposure to sunlight over the past few years, the lack of regular and proper use of sunscreen, the aging of the population, and better screening techniques are the reasons for the escalation in their diagnosis. Squamous cell carcinoma (SCC) comprises nearly 37% of the tumors in this group and can originate from actinic keratosis (AK), which usually presents as pink, often scaly plaques, usually located on the face or scalp.
