Although pure oats are inherently gluten-free, the widespread contamination with gluten-containing grains like wheat, barley, or rye during agricultural and processing stages introduces the potential for gluten exposure through topical application. This raises important questions about whether gluten proteins, when applied to damaged skin, might penetrate the epidermal barrier and contribute to immune responses in genetically predisposed celiac patients, given that even minute amounts of gluten can trigger systemic symptoms. Emerging evidence suggests that transdermal absorption of gluten peptides through impaired skin integrity might bypass the gastrointestinal route, yet the precise mechanisms and clinical significance of this pathway remain poorly understood. The role of compromised skin in facilitating gluten absorption and the possible activation of CD4+ T-cells, mimicking gastrointestinal pathways, warrants further investigation. Additionally, the ability of gluten peptides to reach deeper dermal layers and potentially enter the systemic circulation remains speculative, though theoretically possible in severely disrupted skin barriers. Without clinical and molecular studies to determine the risk of topical gluten exposure, particularly in celiac patients with skin injuries, there remains a potential for undetected immune activation and subsequent adverse health outcomes in this sensitive population.展开更多

Environmental and occupational risk factors, including prolonged exposure to heat, friction, and certain chemicals, have been identified as exacerbating conditions for HS. Yet, there remains a lack of tailored recommendations for modifying work environments to alleviate these triggers. This review presents novel suggestions for work modifications to reduce HS flare-ups, such as implementing breathable, friction-reducing workwear, ergonomic adjustments to minimize pressure on affected areas, and introducing low-irritant hygiene protocols in workplaces with chemical exposure. These recommendations are grounded in emerging evidence linking specific occupational exposures to the exacerbation of HS symptoms. The novelty of this approach lies in its proactive stance, shifting from reactive management of HS symptoms to preventative environmental modifications. Future studies should explore the long-term efficacy of these modifications and investigate the potential for personalized work environment adjustments based on individual patient profiles. Targeted workplace interventions may significantly improve the quality of life for HS patients, highlighting the need for multidisciplinary collaboration between dermatologists, occupational health specialists, and employers.展开更多
