AI Article Synopsis
- * Previous research suggested that human papillomavirus (HPV) might play a role in the development of NS by infecting stem cells, prompting further investigation into this possible connection.
- * This study analyzed 16 NS samples for HPV DNA and related changes, finding no evidence of HPV infection, thus concluding that HPV is likely not a cause of NS.
Article Abstract
Nevus sebaceus (NS) is a common congenital cutaneous hamartoma that typically presents on the scalp and face at birth or in early childhood. Occasionally NS can be associated with the Schimmelpenning-Feuerstein-Mims syndrome, which presents with concomitant severe neurologic, skeletal, cardiovascular, ophthalmic, and genitourologic disorders. In a previous study, maternal transmission of the human papillomavirus (HPV) and infection of ectodermal stem cells by HPV was postulated to result in the development of NS. In this study we aimed to determine the incidence of HPV infection in pediatric NS samples to further clarify the potential link between HPV and the pathogenesis of NS. NS tissue samples (N = 16) were analyzed for HPV DNA using type-specific, real-time polymerase chain reaction (PCR) targeting HPV 6, 11, 16, and 18 and conventional PCR with modified general primers designed for broad-range HPV detection. The tissues were also histologically evaluated for evidence of HPV infection. HPV DNA was not detected in any of the NS tissue samples using PCR and HPV-associated histopathologic changes were absent in all 16 NS tissues. HPV infection is an unlikely etiologic cause of NS.

Department of Pathology, West China Second University Hospital, Sichuan University, Chengdu, China.
Background: Understanding the HPV genotype distribution in invasive cervical cancer (ICC) is essential for vaccine optimization. This study presents a comprehensive analysis of HPV genotypes in ICC tissues from patients in western China, with the aim of informing regional vaccine policy and prevention strategies.
Methods: DNA was extracted from 1,908 paraffin-embedded ICC samples, and 23 HPV genotypes were detected via PCR and reverse dot hybridization gene chip assays.

Objectives: As one type of vaccine policy, the effectiveness and spillover effects of the US CDC vaccine recommendations are inadequately evaluated. This study aims to fully evaluate its impacts on male adults, in addition to children, using better data.
Design: A before-after study design to examine the CDC's 2011 HPV vaccine recommendation for men aged 11-21.

Evidence increasingly indicates that HPV infection plays a pivotal role in the initiation and progression of bladder cancer (BC). Yet, determining the predictive value of HPV-associated genes in BC remains challenging. We identified differentially expressed HPV-associated genes of BC patients from the TCGA and GEO databases.

Introduction: Immunocompromised persons have high risk of persistent human papillomavirus (HPV) infection and HPV-related diseases, and lower immune response to vaccines. This study evaluated the immunogenicity and safety of administering a fourth dose of quadrivalent (4v)HPV vaccine in immunosuppressed women who did not seroconvert after three doses.
Methods: An open-label, not-controlled trial included immunosuppressed women (solid organ transplant patients and women receiving treatment for SLE) who did not seroconvert to at least one of the four HPV vaccine types after three 4vHPV vaccine doses.
Epigenetic Modification of Muscarinic Acetylcholine Receptors in Squamous Cell Carcinoma of the Head and Neck.
Anticancer Res
January 2025
Department of Otolaryngology/Head and Neck Surgery, Hamamatsu University School of Medicine, Shizuoka, Japan;
Background/aim: The five members of the mammalian muscarinic acetylcholine receptor family are encoded by the cholinergic receptor, muscarinic, 1-5 (CHRM1-5) genes. CHRM genes are incriminated in formation of various cancer types, but their roles in head and neck squamous cell carcinoma (HNSCC) are improperly understood. Aberrant epigenetic modifications of specific tumor-suppressor genes and oncogenes are known to promote cancer development.
