Eruptive xanthomas in a patient with severe hypertriglyceridemia: A case report.

BACKGROUND: Xanthomatosis, a metabolic disorder causing yellow growths (xanthomas), poses challenges in lipid metabolism. This case study introduces the first documented instance within China's Yi population, emphasizing the need to explore dietary habits and treatment strategies tailored to this specific community. CASE SUMMARY: Xanthomatosis is a metabolic disorder where lipid metabolism goes awry, resulting in the development of yellowish growths called xanthomas. A male patient, 47 years of age, from China's Yi population, who is obese, visited our dermatology clinic complaining of widespread, non-painful rashes that have been present for two weeks. The patient works as a chef and has a diet that frequently includes oily and greasy foods. This case represents the initial documentation of xanthomatosis within the Yi population in China, offering a theoretical foundation for understanding dietary patterns and treatment options specific to the Yi community. CONCLUSION: The first report of xanthomatosis in the Yi population in China lays a theoretical foundation for understanding Yi dietary patterns and treatment.

Autologous follicular unit extraction transplant for postburn cicatricial alopecia: A single-center's retrospective case series.

BACKGROUND AND RATIONALE: Cicatricial alopecia not only affects patients' appearance but also has negative effects on their physical and mental well-being, as well as their daily lives. Therefore, it is essential to provide proactive treatment to patients. OBJECTIVE: To explore the clinical effects of autologous follicular unit extraction (FUE) transplantation in the treatment of secondary scarring alopecia caused by burn, and to evaluate its effectiveness. METHODS: A retrospective observational study has been conducted, which included 41 patients with secondary scarring alopecia caused by burn. All patients underwent initial autologous FUE hair transplantation surgery, and the occurrence of postoperative complications was monitored. Patient satisfaction was evaluated after 12 months post-surgery. RESULTS: Satisfaction assessments were conducted for all 41 patients. Out of the total, 31 individuals expressed being very satisfied, 7 individuals reported being satisfied, and 3 individuals indicated being not very satisfied. Among the patients, 3 experienced complications, including herpes in the donor area for one patient, temporary hair loss for another patient, and thick scab for the third patient. CONCLUSION: FUE hair transplantation yields positive results for secondary scarring alopecia caused by burn. It offers natural hair growth patterns, minimal trauma, quick recovery, high patient satisfaction, and few complications.

Clinical effects of autologous follicular unit extraction transplantation in the treatment of secondary cicatricial alopecia after infections.

OBJECTIVE: To explore the clinical effects of autologous follicular unit extraction (FUE) transplantation in the treatment of secondary scarring alopecia caused by infections, and to evaluate its effectiveness. METHODS: A retrospective observational study has been conducted, which included nine patients with secondary scarring alopecia caused by infections. All patients underwent initial autologous FUE hair transplantation surgery, and the occurrence of postoperative complications was monitored. Patient satisfaction was evaluated after 12 months post-surgery. RESULTS: At the follow-up, postoperative satisfaction was 88.9% in nine patients, with only one case of postoperative infection and no incidence of skin necrosis, significant bruising and swelling, unnatural appearance or temporary hair loss. CONCLUSIONS: Autologous FUE hair transplantation is an effective method for treating secondary scarring alopecia caused by infections. This procedure is minimally invasive, resulting in high patient satisfaction and minimal complications postoperatively.

Astragaloside IV Promotes Antiphotoaging by Enhancing the Proliferation and Paracrine Activity of Adipose-Derived Stem Cells.

Photoaging is a degenerative biological process. As a kind of pluripotent stem cells, adipose-derived stem cells (ADSCs) are widely used in the treatment of photoaging. Therefore, we aimed to find an effective way to improve the antiaging ability of ADSCs. In this study, we isolated ADSCs and assessed multilineage differentiation ability and markers. Cultured ADSCs were preconditioned with astragaloside IV (ASI) at 10-7, 10-6, and 10-5 M. Cell proliferation was assessed by CCK-8 assay and cytokine secretion by enzyme-linked immunosorbent assay (ELISA). A fibroblast photoaging model was established and cocultured with normal ADSCs or ASI-treated ADSCs. Matrix metalloproteinase-1 (MMP1) and type I procollagen (PC-I) secreted by human dermal fibroblasts were measured by ELISA. The effects of ASI-treated ADSCs on skin texture, including dermal thickness, collagen content, and microvessel density, in a photoaging animal model were analyzed using H&E staining, Masson staining, and CD31 immunohistochemistry, respectively. We found that 10-6 M ASI could significantly promote cell proliferation and stimulate robust secretion of growth factors in ADSCs. Furthermore, our data showed that ASI-treated ADSCs could markedly reverse the ultraviolet B-induced decrease of PC-I secretion and increase of MMP-1 release in fibroblasts. Moreover, in photoaged skin of nude mice, ASI-treated ADSCs significantly increased dermal thickness, collagen content, and microvessel density.
