As a prototype, we present a first-in-kind fully humanized 3D bioprinted skin model as an alternative to animal testing for preclinical research. This model utilizes a plant-derived recombinant human collagen and human skin fibroblasts, melanocytes, and keratinocytes. The 3D bioprinted human skin model expresses involucrin and cytokeratin 14, contains melanin granules, and structurally resembles human skin. However, the morphology of keratinocytes is slightly different, containing a thicker layer of proliferative keratinocytes and a thinner layer of differentiated, cornified keratinocytes. Nevertheless, the model shows epidermal stratification, which indicates skin maturation. Further, the model lacks skin appendages such as hair follicles and sweat glands, as current bioprinting technology cannot deliver distinct cells at the single-cell resolution. Recent advances in 3D bioprinting such as spheroid-based bioprinting show potential to address these limitations. Hence, 3D bioprinting of skin using plant-derived recombinant human collagen, presents significant advantages, including high-throughput production of personalized human skin models, reduction of animal testing, and potential applications in regenerative medicine.</p></div>","PeriodicalId":8203,"journal":{"name":"Archives of Dermatological Research","volume":"317 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A statistically significant reduction in IGA, lesions count, and erythema score was found in both treated sides (p-value < 0.001). Improvement of IGA and non-inflammatory lesions count was better in laser side more than TXA side after end of treatment and follow-up (p-value < 0.05). Improvement of inflammatory lesions count was non-significant in both sides after end of treatment, while after follow-up it was better on laser side. Improvement of erythema score was non-significant between both therapy modalities after end of treatment and follow-up. 1064 nm long-pulsed Nd: YAG laser and intralesional TXA are effective, and safe treatment modalities for acne.

This review article discussed recent advances and challenges of microneedle technology for enhanced topical treatment of skin disorders. It discussed the effective and safe use of microneedles for treating different types of skin conditions like acne, scars, alopecia, melasma, skin rejuvenation, and photo-damage. The drug delivery through the skin was enhanced and rare or permanent adverse effects were not mentioned, while temporary redness and post-inflammatory hyperpigmentation were frequently seen. Microneedling seems to be a generally reliable and secure treatment choice for various skin conditions. More extensive and randomized clinical trials were necessary to ensure their safety and efficacy across diverse populations, conditions, and treatment durations. This trial helps to identify optimal dosages, long-term outcomes, and any adverse effects that may not appear in smaller studies. They also enable comparisons with existing therapies, ensuring the technology’s generalizability and value.

However, patients with delayed regional metastasis from scalp/facial CSCC do very poorly. Historically, prophylactic treatment of the N0 neck for the T1-T2 (as staged in the AJCC 7th edition) face/scalp cancers has not been recommended. This study aims to determine predictors of delayed regional metastases in < 4 cm CSCC of the face and scalp. Methods: We retrospectively analyzed medical records of patients diagnosed regional metastasis of CSCC of the scalp/face at least 6 months after the diagnosis of the primary CSCC at a tertiary academic head and neck clinic during a period between 2012 and 2018. Results: A total of 50 patients with CSCC of the face/scalp were diagnosed and treated for delayed cervical lymph node metastasis during a 6-year period. All patients were male. Areas affected were the scalp, cheeks, and forehead. No patient had neck lymph node metastases at initial presentation for their scalp/face cancer. The presence of perineural invasion in the primary tumor was the only observed predictor of delayed neck lymph node recurrence. We did not observe an association between diameter/depth of the primary skin tumor or lymphovascular invasion and the presence of regional lymph node recurrence. Conclusion: In our review, perineural invasion (PNI) was the one factor predictive of delayed regional lymph node metastasis. This observation confirms the use of PNI to upstage even small CSCC to T3. Prophylactic treatment of the neck in patients with small scalp/face cancers with PNI should be strongly considered, especially in the age of immunotherapy.</p></div>","PeriodicalId":8203,"journal":{"name":"Archives of Dermatological Research","volume":"317 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00403-025-04224-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143821973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We performed a systematic review using PubMed, Scopus and Google Scholar to look at the use of actigraphy in research into psoriasis and sleep disorders.

Actigraphy consistently revealed strong links between pruritus nighttime arousal, and poorer subjective sleep, although next-day psoriasis symptoms did not always worsen. Systematic analyses emphasized actigraphy’s role in measuring nocturnal scratching, supported by emerging smartwatch apps. Psoriatic arthritis studies likewise reported significant sleep disruptions, though evidence remains limited. From these studies, actigraphy presented as a useful tool in both clinical and research contexts, for diagnosing and monitoring sleep disorders among psoriatic patients.
