Article Synopsis
  • - Merkel cell carcinoma (MCC) is often linked to the Merkel cell polyomavirus (MCPyV), particularly when the virus integrates into the host's DNA and leads to mutations in the Large T antigen (LT), which is essential for the virus's cancer-causing properties.
  • - In recent cases involving MCC combined with skin tumors called trichoblastoma and poroma, researchers found evidence of MCC developing from epithelial cells and identified both mutated and wild-type LT sequences.
  • - The findings indicate that some MCC cases may contain intact MCPyV genomes and express certain viral proteins, suggesting a more complex interaction between the virus and cancer than previously understood.

Data regarding elderly melanoma patients treated with anti-PD-1 or anti-CTLA-4 antibodies are in favor of tolerability outcomes that are similar to those of younger counterparts. However, there are very few studies focusing on elderly patients receiving nivolumab combined with ipilimumab (NIVO + IPI). Here, we ask what are the current prescribing patterns of NIVO + IPI in the very elderly population and analyze the tolerance profile.

Merkel cell carcinoma (MCC) is an aggressive skin cancer for which Merkel cell polyomavirus integration and expression of viral oncogenes small T and Large T have been identified as major oncogenic determinants. Recently, a component of the PRC2 complex, the histone methyltransferase enhancer of zeste homolog 2 (EZH2) that induces H3K27 trimethylation as a repressive mark has been proposed as a potential therapeutic target in MCC. Because divergent results have been reported for the levels of EZH2 and trimethylation of lysine 27 on histone 3, we analyzed these factors in a large MCC cohort to identify the molecular determinants of EZH2 activity in MCC and to establish MCC cell lines' sensitivity to EZH2 inhibitors.

Introduction: Despite the existence of multiple assessment scores for psoriasis severity, skin disease with limited skin lesions but significant impairment of quality of life can be difficult to classify, leading to under- or overtreatment. Our objective was to obtain consensus on clinical criteria to classify psoriasis severity in French clinical practice, with a focus on moderate disease, using a modified Delphi method.

Methods: A steering committee (SC) formulated a 22-item questionnaire to classify moderate psoriasis.

Purpose: Hidradenitis suppurativa (HS) is an inflammatory skin disease characterized by recurrent or chronic painful and suppurating lesions in the apocrine gland-bearing regions. The lack of knowledge about HS and its extremely heterogeneous clinical presentation, in terms of both lesion appearance and sites of involvement, frequently delay its diagnosis for several years. Objectives: in this study, using the latent class analysis, it was demonstrated that severity of HS could be evaluated not only with clinical or surgical characteristics but also with gender specificities.

Paediatric psoriasis has been associated with school absenteeism, limitation of physical activities, psychiatric disorders and, in the longer term, with sexual dysfunction and addictions. This raises the hypothesis that childhood onset psoriasis may affect patients' educational development, and further social and professional outcomes. This study evaluated the relationship between childhood onset psoriasis and patients' educational and socioeconomic characteristics, and the development of addictions in adulthood.

Article Synopsis
  • Merkel cell carcinoma (MCC) is a serious skin cancer linked to the Merkel cell polyomavirus (MCPyV) in 80% of cases, with the remaining 20% associated with UV exposure; both types involve the inactivation of the RB1 gene leading to increased SOX2 expression.
  • In a study of 196 MCC tumors, it was found that RB1 loss was present in 27% of MCC cases, indicating a strong correlation with MCPyV-negative status, whereas MCPyV-positive cases remained RB1-positive.
  • SOX2 was shown to be a key diagnostic marker, with 92% of MCC tumors expressing it diffusely compared to only 2% in non-neuro

Although cemiplimab has been approved for locally advanced (la) and metastatic (m) cutaneous squamous-cell carcinomas (CSCCs), its real-life value has not yet been demonstrated. An early-access program enrolled patients with la/mCSCCs to receive cemiplimab. Endpoints were best overall response rate (BOR), progression-free survival (PFS), overall survival (OS), duration of response (DOR) and safety.

Article Synopsis
  • - This study explored how body mass index (BMI) influences the choice and effectiveness of first-line biologic therapies in psoriasis patients, particularly comparing obese (BMI ≥30 kg/m2) and non-obese individuals.
  • - Results showed that while BMI did not affect the choice of most biologics prescribed, obese patients experienced significantly shorter drug survival, primarily due to higher rates of treatment inefficacy.
  • - The findings suggest a need for more tailored pharmacological approaches in treating obese psoriasis patients to improve therapy effectiveness and longevity.

Background: Acne vulgaris has increased in women over the past 10 years; it currently affects 20-30% of women. The physiopathology of adult female acne is distinguished from that of teenagers essentially by two factors: hormonal and inflammatory. On a therapeutic plan, the four types of systemic treatment approved for female acne include cyclines (leading to bacterial resistance); zinc salts (less effective than cyclines); and antiandrogens (risks of phlebitis).
