Background And Aim: The association of microbiota changes with sensitive skin remains controversial until now. Although a strong correlation is detected between skin microbiota distribution and biophysical parameters, there is little knowledge on the link between sensitive skin and skin microbiota in Chinese women. This study aimed to unravel the correlation between facial skin microbiota distribution and skin barriers in Chinese women with sensitive skin.
Materials And Methods: In total, 34 volunteers were enrolled, including 24 subjects with sensitive skin (SS group) and 10 subjects with non-sensitive skin (NS group). The cuticle moisture content, transepidermal water loss (TEWL), and facial skin sebum secretion were measured, and the facial skin surface morphology was evaluated. Sensitive skin samples were collected from the facial (SS-F group) and chest skin of subjects in the SS group (SS-C group), while non-sensitive skin samples were collected from the facial skin of subjects in the NS group (NS-F group). All skin samples were subjected to sequencing.
Results: sequencing detected Actinobacteria, Firmicutes, and Proteobacteria as the three most common microbiota phyla and , , and as the three most common microbiota genera, and there were no significant differences in the relative frequency of Actinobacteria, Firmicutes, or Proteobacteria, or , , or among the SS-F, SS-C, and NS-F groups (>0.05). We detected no significant difference in the diversity of bacterial communities among the SS-F, SS-C, and NS-F groups; however, the Shannon's diversity index was significantly higher in the NS-F group than in the SS-C group. In addition, Spearman correlation analysis showed a correlation between the microbiota genera and skin physiological parameters (<0.05).
Conclusion: This study preliminarily unravels the skin microbiota of sensitive skin using a high-throughput tool, and there are no microbiota genera with strong associations with skin physiological parameters.

Neurofibromatosis type 1 (NF1, formerly Recklinghausen's disease) is a genetic tumor predisposition syndrome in which the mutation of a tumor suppressor gene (neurofibromin) leads to the development of mostly benign neurofibromas of the skin and the central and peripheral nervous systems and malformations or tumors of other organ systems. Patients with NF1 should receive lifelong interdisciplinary care in specialized centers and important treatment decisions should be made by a regularly meeting interdisciplinary panel of experts. Plastic surgery plays an important role in the multidisciplinary management of all clinical forms of NF1-associated peripheral nerve sheath tumors, from cutaneous and subcutaneous to deep nodular and diffuse plexiform neurofibromas.

Objectives: There is no consensus on elective lymphatic dissection of the parotid and neck for nonmelanoma skin cancer (NMSC) due to challenges in detecting occult spread to these regions. This study aimed to summarize clinical data and evaluate correlations between risk factors, nodular metastasis, and the need for elective parotidectomy in patients with cutaneous squamous cell carcinoma (CSCC), Merkel cell carcinoma (MCC), and apocrine carcinoma (AC) of the head and neck, all with clear surgical margins and negative imaging results for regional metastases.
Study Design: We retrospectively reviewed 166 patients with CSCC, one with MCC, and one with AC of the head and neck, all treated surgically between September 2006 and July 2022.
