RESUMEN
This report presents two cases of patients with long-standing, treatment-resistant Hailey-Hailey disease (HHD) who experienced significant symptom relief through a combination therapy of oral naltrexone and dupilumab injections. The therapeutic potential of targeting the Th2 pathway and Ca2+ signaling with dupilumab in managing HHD manifestations is highlighted. The findings suggest that Th2 blockade with dupilumab, in conjunction with naltrexone, effectively controls recalcitrant HHD, indicating a role of cytokine response in altering disease pathogenesis. This case contributes to the growing body of literature on biologic treatments for HHD and suggests avenues for further research in HHD management.
RESUMEN
Background: Many women's shelters across the nation have programs that emphasize and empower women through career workshops and skills training. However, what is not typically addressed is their dermatological and mental health needs, which are equally important. Objective: Through this pilot project, we aim to address the diverse interrelated issues concerning the whole woman and her body/mind systems including skin cancer awareness, skincare, healthy sun habits, self-esteem, mental health, and stress management. By addressing the woman holistically, we hope to positively impact the way she views and values herself. Methods: We partnered with a local women's shelter to host a seminar focused on dermatological and mental health education. Pre- and post-seminar surveys were collected from participants. Surveys were anonymous and aimed to evaluate the success and efficiency of the workshop to guide and improve future seminars. The seminar had three workshops: skin cancer and sun protection, skincare, and mental health and wellness. Upon completion of the seminar, the attendees were provided with the opportunity to receive free skin examinations by two board-certified dermatologists, and referrals were made to Northeast Ohio Medical University's Student-Run Free Clinic. Upon completion of the seminar, attendees were provided with items such as sunscreen, skincare, and mental health resources. Results: The "Skincare from the Inside Out" pilot project proved to be beneficial to residents of both Norma Herr Women's Shelter. Limitations: Limitations of this study were the small sample size (n = 15), due to participation limitations during the COVID-19 pandemic. Conclusion: Ultimately, to reduce the morbidity and mortality of dermatologic conditions associated with homelessness, it is imperative to address upstream social determinants of health. Future development of this pilot project will aim toward educating medical professionals on the unique and complex dermatologic and mental health needs of women experiencing homelessness.
RESUMEN
Carbon nanotube (CNT) fiber electrodes have become increasingly popular electrode materials for neurotransmitter detection with fast-scan cyclic voltammetry (FSCV). The unique properties of CNT fiber electrodes like increased electron transfer, sensitivity, waveform application frequency independence, and resistance to fouling make them ideal biological sensors for FSCV. In particular, their resistance to fouling has been observed for several years, but the specific physical properties which aid in fouling resistance have been debated. Here, we investigate the extent to which the presence of defect sites on the surface attenuate both chemical and biological fouling with FSCV. We compared traditional carbon-fiber microelectrodes (CFMEs) to pristine CNTs and functionalized CNTs. CFMEs and functionalized CNTs are highly disordered with a great deal of defect sites on the surface. The pristine CNTs have fewer defects compared to the purposefully functionalized CNTs and CFMEs. All electrode surfaces were characterized by a combination of scanning electron microscopy (SEM), Raman spectroscopy, and energy dispersive spectroscopy (EDS). Chemical fouling was studied using serotonin, a popular neurotransmitter notoriously known for electrode fouling. To assess biological fouling, electrodes were implanted in brain tissue for 2 h. Defect sites on the carbon were shown to resist biofouling compared to pristine CNTs but were detrimental for serotonin detection. Overall, we provide insight into the extent to which the electrode surface dictates fouling resistance with FSCV. This work provides evidence that careful considerations of the surface of the CNT material are needed when designing sensors for fouling resistance.
